LAS VEGAS, Jan. 7, 2013 /PRNewswire/ -- Today at the International Consumer Electronics Show (CES), Texas Instruments (TI) (NASDAQ: TXN) DLP® Products, to carry on TI's longstanding commitment to the automotive industry, has revealed its latest vision for the future of in-car/vehicle infotainment with groundbreaking augmented reality (AR) head-up displays (HUD), digital dashboards, and center console systems enabled by TI DLP technology. These next-generation systems from TI mark TI DLP's first official entry into the automotive industry, and represent a notable shift forward with regards to higher resolution and brightness, expanded field of view, tactile feedback, distraction-reduced functionality, and interior design flexibility that breaks the design barriers of existing technology. Together with a number of automotive suppliers and manufacturers, TI will be demoing some of the new-era systems across the show floor during CES 2013 to offer a glimpse of what drivers and passengers can possibly experience in their cars in as little as a few years.
To view the multimedia assets associated with this release, please click http://www.prnewswire.com/news-releases/texas-instruments-dlp-technology-set-to-deliver-greater-in-car-infotainment-with-new-innovative-head-up-display-center-console-and-dashboard-systems-185819001.html
Further supporting TI DLP's expansion into the automotive space, Strategy Analytics noted in its automotive electronics report* that through 2018, "High growth application areas (with unit CAAGRs in excess of 50%) include: Pure electric vehicles, head-up displays, drowsiness detection, front LED lighting, stop/start, lane departure warning, and blind spot monitoring."
"DLP technology has long been known as a leader in digital image quality and intelligent display capabilities across a variety of products and applications," said Kent Novak, senior vice president and general manager, Texas Instruments DLP Products. "For us, the world of in-vehicle infotainment, especially augmented reality head-up displays in the near future, can benefit greatly from what we can do with DLP technology, combined with TI's proven automotive processors, sensors and other products. With our partners, we're delivering the same connected, immersive experiences that consumers expect from smartphones, tablets, gaming systems, and more into the cabins of modern cars and vehicles, but in a less distracting and more usable way."
With the unique micromirror structure of DLP technology, TI has been able to develop a compact HUD system with higher brightness and clarity amid driving conditions, a much wider field of view and increased color reproduction over other display types. Software-based augmented reality elements, such as navigational indicators, real-time landmark details, or safety warnings, can be shown in relation to real-world objects in view to help keep the driver focused on the road ahead. Additionally, the size of the HUD image can also be adjusted and positioned on the windshield to best match the line of vision depending on their seating position, and thus improve the driver's ability to stay focused and alert.
For console and dashboard displays, the speed and accuracy of DLP technology, combined with infrared cameras and other TI components, such as the new "Jacinto 6" processor, allow for multipoint, touchscreen interactivity across the entire surface of the console, scalability to any size and shape, including curves, and true tactile comfort and familiarity via integration of physical dials and buttons. Additionally, full-color, high resolution video, animations, and static images to indicate vehicle information, navigation, in-car entertainment, and HVAC controls can be shown simultaneously and even repositioned to best suit the driver and passengers. Additional TI sensors can determine whether it is the driver's or a passenger's hands approaching the console and adjust the images and available functions accordingly for safety.
All DLP-powered HUD, dashboard, and console setups will be able to display content from whatever software programs and formats that manufacturers may choose, whether proprietary or 3rd party commercial/open source.
To experience all of these automotive displays firsthand, along with other new and upcoming products and advancements made possible with TI DLP technology, be sure to check us out at the following CES 2013 events, and visit our partners' exhibits throughout the show floor:

Picture: Vincent Pastore at The Who's Tommy: 15th Anniversary Concert held at the August Wilson Theatre New York City, USA - 15.12.08
Actor Vincent Pastore has settled the $5.5 million (£3.7 million) civil lawsuit filed against him by his ex-fiancee, who accused him of assault.The 62-year-old's former partner, Lisa Regina, 47, alleged Pastore hit her during a dispute in April 2005.
Pastore - who played Salvatore 'Big Pussy' Bonpensiero hit mob show The Sopranos - pleaded guilty in 2005 to attempted assault on Regina and was sentenced to 70 hours of community service.
On Friday (06Feb09), Pastore gave an emotional testimony as part of the trial, admitting they did have a blazing row during a drive to New Jersey; but insisting the argument never turned physical.
The presiding Manhattan judge excused jurors on Tuesday (10Feb09) after announcing the settlement. The terms were not disclosed as WENN went to press.

A Read-only database in a jar?
In Norway, all wines and liquors and beers stronger than 4.75 volume percent are sold at Vinmonopolet a state monopoly (Literally "The Wine Monopoly").
What has this to do with a read only database? Well, I once had an application on my Palm which contained Vinmonopolet's complete catalogue. Every now and then I updated the catalogue and was the able to search for information about their products (they carry a very impressive selection of good wines). The querying possibilities was somewhat limited. E.g. I could only search for wines within certain fixed price ranges, search for wines from only one country/district/area etc.
What I really wanted was an application with poweful searching possibilities: E.g. Show all Pinotage wines from South Africa and all Shiraz wines from Australia where the price is between NOK 130 and 150. Since I'm a programmer this power could be given me by the means of SQL. Yes, I admit that it would not be very user-friendly for the average wine-consumer, but one could imagine SQL queries as an "advanced option".
Ok. To the point. This application could be implemented as a small Java application on top of a SQL database. And yes, it's easy to make such an application with Apache Derby.
The follwing list shows roughly the steps needed to implement my favourite wine application:
- Create an application that populates a database for the intended purpose. Remember to do a proper shutdown of this database. This ensures that the database is checkpointed (see the Derby Reference Manual under the shutdown=true url attribute).
- Create the user application (of course..... ;-)
- Pack the database files and the user application into one jar file. The Derby property derby.storage.tempDirectory needs to be set, and the application need to do the above described shutdown when it is exited (Since a read-only database can be used from several Derby instances simultaneously, eavch instance will create a unique directory under the tempDirectory which will be deleted during shutdown). The database is accessed with the url jdbc:derby:classpath:<path to database>
- Ship your combined application/database jar file together with derby.jar and there you go.
Easy, isn't it? And I can envision a lot of other applications for a read only database. Can you?
2005-10-04 11:20:00 CEST: jwenting's comment is kind of right, so I changed from "read only database" to "read only database in a jar" in title and blurb to make the blog entry more precise.

If you want to dual boot, keeping win8's setup and running `gummiboot --install` and adding an arch entry to ${esp-partition}/loader/entries/ should work fine.Also note that when you try using gummiboot you need your kernel/initrd installed to the ESP so that gummiboot has access to the files.

Kimberley, Kuruman and Zimbabwe
Prayer and Praise Update
Dear Friends
We praise God for the safe returns of our Mission teams and a series of successful seminars, services and shipments throughout Southern Africa.
Mission to Zimbabwe
Border crossings into Marxist Zimbabwe always present a challenge! Corruption, confusion and chaos create daunting obstacles that are frustrating, intimidating and time-wasting. Even after overcoming the bureaucratic obstacle course at the border, there are multiple roadblocks within the country. On this recent Mission, our team passed through over 50 police and army roadblocks!
Mission to Europe Launched the Reformation Society
10 Years ago the Lord led me on an 11 nation Mission to Europe. This was my Report on that watershed event, which led to the establishing of The Reformation Society and Livingstone Fellowship.
Mission to Europe - 2005
This Mission to Europe was both heart-breaking and heart-warming. I travelled across a continent in decline and crisis. Secular Humanism with its materialism and unbelief is pervasive, and, in many surprising places, Islam is on the ascendancy. Yet I had the privilege of ministering in some of the brightest outposts of vibrant spiritual life and dynamic faith.
Crisis and Contrasts
While Europe has a dynamic and rich Christian heritage, most of its inhabitants today barely seem to give it a thought. Most Europeans seem to have forgotten or rejected their Christian heritage. Yet, I witnessed strongholds of Protestant Christianity and dynamic evangelistic churches as far afield as Northern Ireland and Romania.
The Armenian Genocide in Turkey - 100 Years Ago
This article is also viewable as a PowerPoint here.
24 April 2015 marks the 100th anniversary of the launch of the systematic extermination of the Christian Armenians by the Ottoman Turks. The Jihad began with the arrest of 250 Christian leaders in Constantinople (what is today called Istanbul), on 24 April 1915. Over 1.5 million Christians were slaughtered by the Muslims in Turkey during 1915.
Corruption and Cruelty
The Ottoman Empire declined into corruption and degeneracy from the beginning. When Sultan Murab III died in AD 1595, his son Muhammad had his 19 brothers murdered to prevent them from claiming "his throne". He also had seven of his father's pregnant concubines sown into sacks and thrown into the river. Many of his nephews were incarcerated in "the cage". Sultan Ibrahim threw his grand Vizier into a cistern. One morning, after an orgy, Ibrahim had all 300 women of his harem put into sacks and thrown into the Bosporus. Only one survived by being picked up by a ship bound for France. When Ibrahim was finally assassinated, the Ottoman Empire was torn apart by more corruption, nepotism, inefficiency, misrule and power struggles.

Publius Aelius Aelianus
Aelianus (P. Aelius Aelianus) was a senior officer in the Roman Army in the mid-Third Century AD who rose from relatively lowly origins to become the prefect of a legion under the Emperor Gallienus He was one of the earliest beneficiaries of Gallienus's policy that effectively excluded senators from army commands in favour of career-soldiers of equestrian rank. His later life is obscure.
He was possibly procurator (i.e. Chief Financial Officer) of Epirus in the late-260s, but the foremost authorities query this identification. However, there are stronger grounds for believing that he was appointed a praeses (provincial governor of equestrian rank) ) in Africa, most likely under the Emperor Probus.
The sum total of our knowledge of this man derives from five epigraph inscriptions from:
(a) A commemorative stone found in Poetovio in Pannonia Superior (now Ptuj in present-day Slovenia); [1]
(b) The sarcophagus Aelianus dedicated to the memory of his parents found at Obuda, a district of modern Budapest on the west bank of the River Danube which was the site of Aquincum Castrum, the base of Legio II Adiutrix;[2]
(c) An altar dedicated to Herculi Augusti - i.e. to the Majestic Hercules - from Szentendre, the site of Ulcisia Castra an auxiliary fortress 12 km north of Aquincum;[3]
(d) A stone from Photike in the Roman province of Epirus, nowadays a province of Greece;[4] and
(e) A stone from Zucchabar in Algeria, in the Roman province of Mauritania Caesaensis.[5]
The last four of these inscriptions are analysed in great detail by T. Nagy.[6] This article largely reflects Prof. Nagy's findings and conclusions.
It is likely that Aelianus was born at Aquincum in Pannonia Inferior which, as noted above, was the base of Legio II Adiutrix. His father was Martialis (P. Aelius) who had been a Custos Armorum (i.e. Warden of the Armoury) of Legio II (obviously he was described as ex custode armorum - i.e.'formerly Warden etc.' on his tomb) and his mother Fl. Agathe.
The gentilicum 'Aelius' suggests that the family was either descended from one of the settlers who arrived in Pannonia in the century after the Roman conquest or from one of many native Pannonian clans that was given Roman citizenship when the future Emperor Hadrian was governor in the early years of the second century AD (around 106AD).[6] If the Aelius ancestor was indeed enfranchised during the reign of Hadrian or his successeor, Antoninus Pius he would have taken the name of the imperial dynasty as his own nomen as was the custom of the day. Thus by this interpretation of the onomastics Aelianus's clan had been Roman citizens for well over 100 years by the time he dedicated his parents' sarcophagus and possibly more than 150 years and it is likely that the family had had connections with Legio II for generations.
Early career[edit]
It can be safely assumed that, as a castrensis (i.e. 'Son of the Camp' - born of a serving soldier), Aelianus would have enlisted at the earliest age – i.e. 18-20 – probably in his father's legion. It is likely that he would have risen ex caliga – i.e. 'from the ranks of those who wear hobnailed sandals' (the footwear of legionary rankers).[6] However, given that patronage and influence were the major determinants of advancement in the Roman Army, it is not unreasonable to suppose that, as the son of a principalis, Aelianus would have enjoyed some advantages vis-à-vis his fellow-recruits that would have helped promote his career.
Nevertheless, the inscriptions cited make it clear beyond all doubt that Aelianus showed himself a highly capable soldier and probably a lucky one as well who prospered in the conditions of crisis that prevailed on Rome's northern frontiers in the middle years of the Third Century AD.
Although he probably enlisted in Legio II and certainly commanded it at a high point of his career, he is unlikely to have served solely with that legion. Like many of the soldiers who rose to prominence in his era, it seems safer to postulate that he rose through the centurionate receiving progressively more senior postings in different legions before he achieved primipilaris status (i.e. had been promoted primus pilus of a legion and had served a year at that rank) and then continued his career as an equestrian officer[7]
Apogée in the Balkans[edit]
The first Aelianus inscription cited above is incomplete, but mentions an 'Aelius Aelianus', a man of egregius equestrian rank, who was the commander of detachments drawn from the four legions of the Pannonian provinces at Poetovio, a highly strategic fortress commanding the approaches to Italy through the Julian Alps. Whether or not this Aelianus was that who is the subject of this article is uncertain. Prof. Nagy and Jones et al. did not make the connection. However, Fitz believed that they were one and the same person).[8] Fitz also suggests that the inscription is dated around about the early 260s AD - i.e. around the time that Gallienus recovered the region after the death of the usurper Regalianus.
Fitz's supposition that the Aelianus referred to was our Aelianus seems plausible, partly because: (i) it seems highly unlikely that there would have been two very senior officers of that name commissioning lapidary inscriptions in Pannonia within a very short period yet making no attempt to differentiate themselves from each other; and (ii) the Poetovio posting seems a highly probable career move for a man who was soon to be re-manifested as one of Gallienus's legionary prefects.
As the Praefectus Legionis II Adiutricis referred to on the Aquincum sarcophagus, Aelianus is likely to have been one of the earliest beneficiaries of Gallienus's policy of excluding senators from army commands in favour of professional equestrian officers who would, more often than not, have risen from the ranks. Nagy points out that, as a non-senator, Aelianus would not have been given this posting prior to the Persian captivity in 260 AD of Gallienus's father and senior Augustus, the Emperor Valerian. The measures that opened the legionary commands to equestrian officers were taken by Gallienus during his sole reign - possibly in 261 AD. Nor could he have been given it after 267 in which year we know that Valerius Marcellinus was in command of Legio II.[9] Nagy is inclined to ascribe Aelianus's promotion to the earlier part of this five year 'window'.
The Ulcisia altar describes the dedicator, P. Aelius Aelianus, as prefect of the Second legion, thus confirming that he was the same man as the one who had commissioned the sarcophagus of Martialis and Fl. Agatha. It adds the additional information that he was protector nostri augusti Gallieni – i.e. 'Protector of Our Majestic Lord Gallienus'. He was, thus, one of the earliest known recipients of that title. However, that the honorific should refer to 'Our Majestic Gallienus' rather than to 'Our Majestic Lords' (i.e. Valerian and Gallienus) as in the case of L. Petronius Taurus Volusianus shows that the inscription can be dated to the period of Gallienus's sole reign, but in the early part of that period when the honour was still awarded to senior officers rather than centurions as was later the case.(See Protectores Augusti Nostri. His possession of the title also suggests that when he commanded Leg. II Adjutrix that unit was brigaded with the Imperial comitatus rather than serving with the provincial garrison of Pannonia Inferior - its usual station during High Empire period.[10]
More important, perhaps, the inscription states that he was praefectus legionis agens vice legati – i.e. 'Prefect of the Legion acting on behalf of the (senatorial) legate' who we know was never to be appointed. However, the use of this terminology - presumably a formula to ensure that the prefect had the legal authority of a legate - seems to throw doubt on the proposition advanced by many historians [11] that Gallienus had always intended the removal of senators from legionary commands as a permanent reform as opposed to an expedient resorted to in the crisis following the captivity of Valerian that was never reversed. In other words, it suggests Aurelius Victor was mistaken when he said that Gallienus had issued an edict incorporating the change in law.[12] If such a law had been promulgated the formula agens vices legati would surely have been superfluous. Recent scholarship has suggested that the real purpose of Gallienus's Edict was not to exclude senators from army appointments - otherwise why did he continue to appoint senatorial provincial governors with supreme military authority within their provinciae(?) - but to make it possible for the Emperor to appoint equestrian officers to these positions thus broadening his powers choice at a time when the Empire was under particular pressure to find commanders with adequate military experience.[13]
Later career[edit]
The Photike inscription is in Greek and it identifies an 'Aelius Aelianus' as the chief financial officer (Lat. Procurator) of the province of Epirus sometime in the period 275-80 AD who had previously taken part in the census of the frontier province of Noricum. Nagy does not believe that the Aelianus who was a legionary prefect before 266 could have held these offices at a later date as the posts were lower in the equestrian career structure.
On the other hand, Nagy considers that the 'Aelius Aelianus' who was identified as praeses provinciae Mauritaniae Caesarensis (i.e. 'Governor of the province of Mauritania Caesarensis') in around 276 could well have been the same man as the praefectus legionis II in Aquincum of a dozen years earlier. This would have been a promotion quite compatible with what we know of the equestrian career structure. Furthermore, it would also fit in with the known tendency to appoint military men to governing posts in Africa from the later years of the Emperor Probus onwards to deal with increased restlessness on the part of the Berber tribes of the Mauretanian interior. As Nagy observes, the Aelianus who cut his teeth fighting the Sarmatian steppe nomads in Illyria would have been well qualified to deal with the Moorish raiders of Rome's west African provinces.[14]
Social status[edit]
It is interesting to note that when he held this office Aelianus was still a Vir Egregius (i.e. 'Select Man') indicating that he was still a member of the Third Class of the Roman equestrian order just as he has been as Praefectus Legionis. In this he may be compared with Lucius Flavius Aper who had governed Pannonia Inferior at this status. On the other hand Lucius Aurelius Marcianus had governed Dalmatia as a Vir Perfectissismus - i.e. a member of the Second Class of the Equestrian Order - although he may have had that status before his appointment. This may indicate that there was no necessary connection between an officer's substantive rank and his social status which depended more on his relations with the Imperial court.

This invention relates generally to temperature compensation of field devices, and in particular to compensation utilizing a temperature-averaging sensor that characterizes an extended region of the field device.
The term "field device" refers to a broad range of process management devices designed to measure and control process parameters such as pressure, temperature and flow rate. Field devices include both transmitters, which are configured to measure or sense a process parameter with a sensor module, and controllers, which are configured to modify or control such a parameter with a control module (for example, by positioning a valve or regulating a pressure). Field devices also include multi-sensor transmitters such as pressure/temperature transmitters, and integrated controllers comprising both sensor modules and control modules (for example, integrated flow controllers). Field devices can also utilize more generalized field modules, which can incorporate a range of related measurement and control functions (as, for example, in an integrated hydrostatic tank gauge system).
Field devices have broad utility in applications that include manufacturing, fluid processing, food preparation and environmental control, and are applied to a wide range of process materials including air, water, liquid hydrocarbon fuels, natural gas, glues, resins, thin films, and thermoplastics such as polyvinyl chloride (PVC). Most of these applications require at least some form of temperature compensation, which in general must address both direct and indirect effects. Direct effects include temperature dependencies in the process material itself, particularly with respect to pressure and volume-related measurements. Indirect effects include temperature dependencies in the field device, such as thermoelectric sensor response, temperature dependencies in analog-to-digital (A/D) or digital-to-analog (D/A) converters, and other related effects.
Direct temperature compensation requires measurement of the process material, which often implicates large inventories and flow volumes. This is particularly true, for example, in energy-sector applications like petroleum refining and bulk fuel transportation, where process temperatures may vary substantially even within a single flow unit or storage volume. Direct temperature compensation therefore employs multi-spot temperature sensors, or, alternatively, temperature-averaging sensors that characterize an extended region of the process material.
Temperature compensation directed toward field devices, on the other hand, has traditionally relied upon single-spot compensation sensors. Field devices are generally small as compared to typical process volumes, and, in the idealized case, temperatures may not vary significantly on this scale. Moreover, because field devices emphasize simple, compact, and robust design methods, it can in any case be difficult for them to incorporate complex multi-spot compensation systems.
Nonetheless, under actual operating conditions significantly non-uniform temperature conditions do arise. Process heat flow, maintenance operations, and changing ambient conditions all produce temperature gradients, which can sometimes exceed 10-20� C. across a typical field device. Under such conditions a single-point sensor may not adequately characterize the field device, resulting in signal drift, bias, and other effects. Thus there remains a need for a temperature compensation technology that can overcome this deficiency, and so improve upon the prior art.
An average-temperature compensated field device utilizes a sensor module to characterize a process parameter associated with a process material, and a temperature-averaging sensor to characterize an extended region within the field device. The sensor module and temperature-averaging sensor produce analog signals, which are digitized by an analog-to-digital (A/D) converter. A microprocessor generates a compensated output as a function of the digitized signals, and an interface transmits the output utilizing a commercially-available communication protocol.
In various embodiments the sensor module comprises a pressure transducer, a thermocouple transducer, a flow meter, a level sensor, or another form of sensor. Alternatively, the field device is a multi-sensor device, combining a number of such functionalities. The temperature-averaging sensor typically comprises a flexible resistance-temperature device (or RTD), and the communication protocol is a standard analog protocol, a hybrid analog-digital (or HART�) protocol, or a digital protocol such as Fieldbus, and employs either a wireless or hard-wired control bus technology.
An average-temperature compensated controller comprises the average temperature sensor, an electronics module, and a control module. The electronics module is configured to receive a process control input, and to generate a compensated control output as a function of the process control input and the compensation signal from the temperature-averaging sensor. The control module is configured to influence a process parameter as a function of the compensated control output. In various embodiments the control module comprises a temperature controller, a pressure regulator, or a fluid level controller. In other embodiments the control module comprises a valve positioner or a valve actuator, and the controller further comprises a sensor module configured to characterize a flow rate. In these embodiments the controller comprises an integrated flow controller.
A method of temperature-averaging field device compensation comprises generating a process signal that characterizes a process parameter, sensing an average temperature over an extended region of the field device, compensating the process signal as a function of the average temperature, and generating an output as a function of the compensated process signal. In one embodiment the process signal comprises a sensor signal, and the output comprises a compensated output. In another embodiment the process signal comprises a process control input, and the output comprises a compensated process control output. Alternatively, the field device is an integrated controller, which combines such functionalities.
Housing 11 is comprised of a durable material such as metal or a durable plastic. The housing comprises internal mounting structures configured to secure internal components including sensors 12 and 13, and electronics module 14A. Housing 11 insulates these internal components, shields them from adverse environmental conditions such as moisture or corrosive agents, and protects them from contact with process machinery, tools, falling objects, or other potential hazards. Housing 11 also provides coupling structures configured to couple transmitter 11 to a process structure containing a process material.
Sensor module 12 is configured to generate an analog sensor signal that characterizes a physical parameter (a process parameter) associated with the process material. In various embodiments, for example, sensor module 12 comprises a pressure sensor such as a piezoresistive pressure sensor, a capacitive pressure sensor, or an electromechanical pressure sensor, each of which are configured to characterize (or measure) a process pressure. Alternatively, sensor module 12 comprises a temperature sensor such as a thermocouple temperature transducer, a flow meter such as a mass flow meter, a fluid level sensor, or another form of sensor. Transmitter 10 also has multi-sensor embodiments, such as a pressure/temperature transmitter which comprises a number of sensor modules 12.
Temperature-averaging sensor (Tavg sensor) 13 comprises a temperature-responsive element such as a resistance-temperature device (an RTD). Temperature-averaging sensor 13 has an extended sensitivity area, as distinguished from single-spot (or single-point) sensors in the prior art, and from multi-spot (or multi-point) sensors comprising a number of discrete single-spot sensors. Sensor 13 generates an analog compensation signal that characterizes an extended region within transmitter 10, providing a more representative compensation signal that is adaptable to a variety of field module geometries and field device applications.
In embodiments where sensor module 12 comprises a thermocouple temperature transducer, Tavg sensor 13 facilitates cold-junction compensation. Because Tavg sensor 13 is not limited in sensitivity to a single point proximate the thermocouple, however, it is also configurable to characterize temperature-dependent components in electronics module 14A, or other temperature-dependent elements of the field device. The Tavg sensor is further configurable to characterize regions of housing 11 that are proximate a process material, such that Tavg sensor 13 also characterizes a process temperature.
Electronics module 14A comprises analog-to-digital converters (A/Ds) 15A, microprocessor 16 and interface (I/F) 17. In some embodiments the electronics module also comprises pre-amplifier components for pre-amplifying analog signals from sensor module 12 and Tavg sensor 13. Alternatively, sensor module 12 or Tavg sensor 13 comprise integrated preamplifier components.
A/Ds 15A digitize analog signals from primary sensor 12 and Tavg sensor 13. The A/Ds have linear, bilinear and non-linear embodiments, as appropriate to the particular sensitivity and scale range of sensor module 12 and Tavg sensor 13. The A/Ds are variously flash A/Ds, utilize sigma-delta modulation, or employ another conversion architecture, as available from a variety of commercial vendors. In some embodiments electronics module 14A comprises a unitary A/D 15A, configured to digitize signals from both primary sensor 12 and Tavg sensor 13.
Microprocessor 16 clocks A/D 15A, and, optionally, sets A/D parameters such as bilinear breakpoint or conversion scale. The microprocessor also compensates the digitized sensor signal as a function of the digitized compensation signal, generating a compensated sensor output. Typically, compensation is initially performed as a pre-calibrated (factory-set) function of the digitized signals, but both transmitters and other, more generalized field devices typically provide for field-based calibrations as well.
Microprocessor 16 provides the compensated sensor output to interface (I/F) 17. Microprocessor 16 is also configurable to provide the compensation signal, in either digital or analog form, as well as a date stamp, a time stamp, or diagnostic signals representing the operating state of primary sensor 12 and Tavg sensor 13. In some embodiments, microprocessor 16 comprises additional functionality to linearize the sensor signal, re-range the transmitter, adjust damping characteristics, or provide additional diagnostic signals.
Interface 17 transmits the compensated output to a hand-held controller, a remote operator, or an automated control system such as DeltaV, as available from commercial vendors including Emerson Process Management. In one embodiment, I/F 17 supports a Profibus/Fieldbus communication protocol, which is a bi-directional digital protocol. In other embodiments, I/F 17 supports a standard 4-20 mA analog signal protocol, or a hybrid protocol such as HART�, which superimposes digital communications on the standard analog signal. The interface is also configurable to communicate via a wireless radio-frequency (RF) transmitter, for example a 902-928 MHz signal compatible with a HART-based 1420 Wireless gateway, also available from Emerson Process Management.
In operation of transmitter 10, primary sensor 12 and Tavg sensor 13 provide analog signals to A/D 15A. Microprocessor 16 clocks the A/Ds, which digitize the analog signals, converting them to digital signals. Microprocessor 16 compensates the digital sensor signal as a function of the digital compensation signal, generating a compensated sensor output for I/F 17. The interface transmits the compensated output according to one or more of the communication protocols described above.
In the HART and Fieldbus embodiments, I/F 17 receives digital control signals, which are used to request an A/D clock by microprocessor 16, to provide A/D conversion parameters, to set date and time stamp information, to facilitate calibration or diagnostics, or for other process management and control purposes. In these embodiments I/F 17 can also transmit various diagnostic signals in digital form.
Housing 11 and Tavg sensor 13 are operable as described above with respect to transmitter 10 of
Electronics module 14B comprises A/D 15A, microprocessor 16 and I/F 17, and may comprise pre-amplifier components as described above. Electronics module 14B also comprises digital-to-analog (D/A) converter 15B.
Control module 19 variously comprises, for example, a commercially available temperature controller, a pressure regulator, a fluid level controller, a valve positioner, a valve actuator, or a flow controller. Alternatively, control module 19 is a more generalized field module with both measurement and control functionality, such as a component of a hydrostatic tank gauge system. Regardless of particular embodiment, however, control module 19 applies temperature-dependent measurement and control technology to temperature-dependent process parameters, and so benefits from temperature compensation analogous to that described above for sensor module 12 and transmitter 10.
In operation of field device 18, I/F 17 is configured to receive a process control input via a standard analog, HART, or Fieldbus communication protocol. Microprocessor 16 compensates the control signal as a function of the compensation signal from Tavg sensor 13, and then clocks D/A converter 15B in order to produce a compensated (analog) control output for control module 19. The compensation function is either factory calibrated or field calibrated, or depends upon a combination of such calibrations as described above.
The compensated control output comprises a current level, a variable-width electronic pulse, a pneumatic pressure, or another control output. Control module 19 is configured to influence the process parameter as a function of the control output, for example by actuating or positioning a valve, or by providing current to a resistive heater. Essentially, whereas a sensor module is configured to passively characterize a process parameter (that is, by measuring it), control module 19 is configured to actively characterize the parameter (that is, by physically influencing or altering it).
Note that
In the embodiment of
The relative sizes, shapes and positions of the components in
Specifically, Tavg sensor 13 is configured to generate a compensation signal that characterizes an extended region of transmitter 10, or of any generalized field device. For example, Tavg sensor 13 is configurable to simultaneously characterize temperatures proximate both sensor module 12 and electronics module 14A, as well as regions of housing 11 proximate other temperature-dependent components, or, alternatively, a process material. This adaptability is particularly important when the field device is subject to non-uniform temperature effects.
The temperature gradient is described by isotherms T1, T2 and T3, which characterize a non-uniform temperature gradient that generally decreases from the top left of
Single-spot temperature compensation techniques, as are typical of the prior art, require a compromise between the optimal placement for temperature equilibrium (that is, when the temperature is the same everywhere inside the field device), and the unpredictable effects of non-uniform operating conditions like those in
Temperature-averaging sensor 13 is less subject to signal drift, because its extended sensitivity region simultaneously characterizes different temperature regions across the gradient. This provides a more representative compensation signal, and allows for faster response to changing temperatures. In a flexible-sensor embodiment, furthermore, Tavg sensor 13 can be conformed to the geometry of almost any field device, and specifically configured for both equilibrium and non-equilibrium temperature conditions.
Quasi-steady-state gradients like that in
Temperature-averaging sensor 13 is less subject to bias than the prior art, because it has an extended sensitivity area that yields a more representative compensation signal than a single-spot sensor. Tavg sensor 13 is moreover configurable to provide a single compensation signal in a unified, compact package, as opposed to more complex multi-spot (multi-point) systems that require a number of discrete single-spot components.
Lead wires 41 and 42 are electrically coupled to opposite ends of wire core 44, such that lead wires 41 and wire core 44 form an electrical path along the length of Tavg sensor 13. Connections between the lead wires and external electronics are discussed with respect to
Sheath 43 is configured to protect and electrically insulate wire core 44. The sheath comprises a flexible conduit, a flexible hose, a flexible plastic coating, or another form of sheath material. The cross-sectional geometry of sheath 43 is variously substantially circular, substantially oblong, or otherwise, such that sheath 43 generally conforms to the cross-sectional geometry of wire core 44.
Wire core 44 is a resistive conducting wire core, comprised of DIN-grade (or European standard) platinum, reference-grade (at least 99.999% pure) platinum, nickel, copper, a nickel/iron alloy, or another material with temperature-dependent resistivity. Wire core 44 is typically wound around an insulating core winding (which is not shown), or, alternatively, coiled within a mandrel (also not shown). Such wire cores are provided with RTDs available from Weed Instruments of Round Rock, Tex.; RdF Corporation of Hudson, New Hampshire; Emerson Process Management, and other commercial vendors. Sheath 43, wire core 44 and the core winding or mandrel are typically flexible, allowing Tavg sensor 13 to conform to a variety of field device geometries as discussed above.
In the embodiment of
The preferential-sensitivity embodiment of
The two-wire bridge provides a relatively simple, robust output wiring configuration. Bridge resistors 51, 52 and 53 are coupled to lead wires 41 and 42, and to A/D converter 15A. Variable potential supply 54 provides current through Tavg sensor 13, as limited by bridge resistor 53. The average temperature along the RTD is a function of the resistance of wire core 44, which is determined from Ohm's Law:
As indicated by
Self-heating causes the wire core to have a slightly higher temperature than its surrounding environment, which changes its resistance and so introduces a self-heating component into the compensation signal. Self-heating can be corrected for by determining the self-heating index (SHI), which is simply the slope of the (approximately linear) relationship between RTD resistance and self-heating power. That is,
Essentially, the SHI is the ratio of the change in resistance to the change in self-heating power. The self-heating power is found via Eq. 2, using current I and voltage V as measured across the RTD, and the resistance is found via Ohm's Law (Eq. 1). Once the SHI is determined the RTD signal can be corrected for any current I and any voltage V, by reducing resistance R by AR in proportion to the self-heating power:
To autocorrect Tavg sensor 13 for the effects of self-heating, microprocessor 16 provides two different currents through the wire core, and calculates the self-heating index (SHI) via Eq. 3. The self-heating index is then used in the compensation function to correct resistance R for the effect of current flow through Tavg sensor 13, using Eq. 4 or another similar algorithm. This reduces the effect of self-heating on the compensation signal, and provides for a more accurate compensated sensor output.
The autocorrected embodiments of
The present invention has been described with reference to preferred embodiments. Workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.

Poll: What Was the Best Guitar Album of 2000?
Poll: What Was the Best Guitar Album of 2000?
The year opened with Prince playing "1999" at midnight in New York City. He vowed to never play the song live again.
It ended (releatively -- December 2) with what was supposed to be the Smashing Pumpkins' last show, at the Metro Club in Chicago.
In between, music events were a-plenty. Santana tied Michael Jackson's record for winning eight Grammy Awards in one night. Metallica sued Napster over copyright infringement, creating an internet media firestorm, and Rage Against the Machine split up after the departure of singer Zack de la Rocha.
And all these albums were released. In retrospect, it was a good year for electric guitar fans. Rock music was on something of an upswing, with high-profile releases from Pantera, Iron Maiden, Black Label Society and AC/DC -- who even appeared on MTV's Total Request Live with Carson Daly.
But for all 2000 brought, there can be only one fan-favorite guitar album, as voted by you. So check out the poll below and let us know what you think.
