I believe this was the second full length book that Agatha Christie wrote and this may be the reason it appears slightly muddled however it is definitely not her worst and as the first of the T and T novels it offers some important background to some of her following books including the EXCELLENT N or M.I thoroughly enjoyed this book but I do not recommend it as a first time 'Christie' read.

The support assembly is rotatably mounted to the main body for allowing the main body to be rolled along a surface. The support assembly also houses a component of the appliance, such as a motor for driving a surface-agitating device. Alternatively, or additionally, the support assembly may accommodate a fluid inlet for receiving fluid flow, a fluid outlet for exhausting fluid and a device for acting on the fluid flow received by the inlet such as a filter or suction apparatus.
11. A vacuum cleaner comprising the surface treating appliance of claim 1. Description
REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. Ser. No. 11/868,809, filed Oct. 8, 2007, now U.S. Pat. No. 7,581,285, and a continuation of U.S. Ser. No. 10/522,339, filed Jan. 25, 2005, now U.S. Pat. No. 7,610,653, which is a national stage application under 35 USC 371 of International Application No. PCT/GB2003/003132, filed Jul. 18, 2003, which claims the priority of United Kingdom Application No. 0218426.5, filed Aug. 9, 2002, the contents of all of which are incorporated herein by reference.
FIELD OF THE INVENTION This invention relates to a surface treating appliance, such as a vacuum cleaner.
BACKGROUND OF THE INVENTION Surface treating appliances such as vacuum cleaners and floor polishers are well known. The majority of vacuum cleaners are either of the �upright� type or of the �cylinder� type, called canister or barrel cleaners in some countries. An example of an upright vacuum cleaner manufactured by Dyson Limited under the name DC04 (�DC04� is a trade mark of Dyson Limited) is shown in FIG. 1. The vacuum cleaner comprises a main body 102 which houses the main components of the vacuum cleaner. A lower part 106 of the main body houses a motor and fan for drawing dirty air into the machine and the main body also houses some form of separating apparatus 104 for separating dirt, dust and other debris from a dirty airflow drawn in by the fan. The main body 102 also houses filters for trapping fine particles in the cleaned airflow. A cleaner head 108 is rotatably mounted, about points A, to the lower end of the main body 102. The axis about which the cleaner head rotates is horizontally directed. A supporting wheel 107 is mounted on each side of the lower part 106 of the main body, in a fixed relationship to the main body 102. In use, a user reclines the main body 102 of the vacuum cleaner and then pushes and pulls a handle 116 which is fixed to the main body of the cleaner. The vacuum cleaner rolls along the floor surface on the supporting wheels 107.
A further, less common, type of vacuum cleaner is a �stick vac�, which is so-called because it has a very slender stick-like main body. An example is shown in EP 1,136,029.
SUMMARY OF THE INVENTION The present invention seeks to provide a surface treating appliance with improved maneuverability.
The term �surface treating appliance� is intended to have a broad meaning, and includes a wide range of machines having a head for travelling over a surface to clean or treat the surface in some manner. It includes, inter alia, machines which apply suction to the surface so as to draw material from it, such as vacuum cleaners (dry, wet and wet/dry), as well as machines which apply material to the surface, such as polishing/waxing machines, pressure washing machines, ground marking machines and shampooing machines. It also includes lawn mowers and other cutting machines.
DETAILED DESCRIPTION OF THE INVENTION FIGS. 3-13 show a first embodiment of a vacuum cleaner 200 with a main body 210, a roller assembly 220 and a cleaner head 230.
The shape of the arcuate region 585 of the roller surface is also selected such that the distance between the centre of mass 590 of the roller assembly and a point on the surface of the roller shell increases as one moves along the arcuate surface away from the central region 580. The effect of this shape is that it requires an increasingly greater force to turn the roller, as the roller is turned further from the normal straight running position. The diameter of the roller shell 510 at each end of its longitudinal axis determines the extent to which the main body can roll to one side. This is chosen such that there will be sufficient clearance between the main body�and particularly the ducts 531, 535 at the point at which they enter the roller assembly�and the floor surface in this most extreme position.
Part of a further alternative connection between the main body and the cleaner head is illustrated in FIGS. 29 a, b and c. As before, the connection comprises a yoke 901, each end portion 902, 903 of the yoke being connectable to the main body about the rotational axis of the roller assembly. The central portion of the yoke comprises a joint 904 that is connectable to a cleaner head (not shown), either directly or via an intermediate arm, such as those illustrate in FIGS. 7 and 27. The connection further comprises a locking arm 905 that is pivotably attached to the yoke 901 at the end portions 902, 903, and extends along it. The locking arm 905 has a central extending portion 906, which may be rigid with respect to the arm or may be pivotably attached to it. The central portion 906 can be received by a complementary notch arrangement 907 in the joint 904, so as to �lock� the joint and prevent it from being rotated when, for example, the appliance is in the standing position. The linkage is shown in the locked position in FIG. 29 a. Thus, the cleaner head itself provides extra stability to the appliance in the standing position. Resilient means (not shown) may be provided to bias the central portion 906 of the locking arm 905 towards the joint when the appliance is in the standing position, so as to provide automatic locking of the joint.

Associated Press Hundreds of riot police officers in Iran beat protesters and fired tear gas Monday to contain the most significant street protests since the end of the 2009 uprising there, as security forces around the region moved — sometimes brutally — to prevent new unrest in sympathy with the opposition victory in Egypt.The size of the protests in Iran was unclear. Witness accounts and news reports from inside the country suggested that perhaps 20,000 to 30,000 demonstrators in several cities defied strong warnings and took to the streets.The unrest was an acute embarrassment for Iranian leaders, who had sought to portray the toppling of two secular rulers, Zine el-Abidine Ben Ali in Tunisia and Hosni Mubarak in Egypt, as a triumph of popular support for Islam in the Arab world. They had refused permission to Iranian opposition groups seeking to march in solidarity with the Egyptians, and warned journalists and photographers based in the country, with success, not to report on the protests.Iranian demonstrators portrayed the Arab insurrections as a different kind of triumph. “Mubarak, Ben Ali, now it’s time for Sayyid Ali!” Iranian protesters chanted in Persian on videos posted online that appeared to be from Tehran, referring to the country’s supreme leader, Ayatollah Ali Khamenei.
The Iranian authorities have shown that they will not hesitate to crush demonstrations with deadly force. Other governments across the Middle East and the Persian Gulf also moved aggressively to stamp out protests on Monday. Continue reading the main story
In Egypt, the army stuck to its promise not to attack demonstrators, but the death toll during the protests leading to Mr. Mubarak’s downfall reached about 300 people, according to the United Nations and human rights organizations. Most fatalities appeared to have occurred when pro-government thugs attacked demonstrators.On Monday, the police in Bahrain fired rubber bullets and tear gas into crowds of peaceful protesters from the Shiite majority population. So much tear gas was fired that the officers themselves vomited. In Yemen, hundreds of student protesters clashed with pro-government forces in the fourth straight day of protests.In the central Iranian city of Isfahan, many demonstrators were arrested after security forces clashed with them, reports said, and sporadic messages from inside Iran indicated that there had also been protests in Shiraz, Mashhad and Rasht.Numbers were hard to assess, given government threats against journalists who tried to cover the protests. Aliakbar Mousavi Khoeini, a former member of Parliament now living in exile in the United States, said that 20,000 to 30,000 people had taken part across the country.Ayatollah Khamenei and the Iranian establishment have tried to depict the Arab movements as a long-awaited echo of the 1979 Islamic Revolution, though Islamist parties had a low profile in both the Egyptian and Tunisian uprisings. The Iranian opposition has painted the Arab protests as an echo of its own anti-government movement in 2009, when citizens demanded basic rights like freedom of assembly and freedom of speech after the disputed re-election of President Mahmoud Ahmadinejad.Mehdi Karroubi, an opposition leader, said in an interview last week that the opposition had decided to organize a day of demonstrations to underscore the double standard of the government in lauding protesters in Arab countries while suppressing those at home. Mr. Karroubi has been put under house arrest, with outside communication links severed, opposition reports said, as has Mir Hussein Moussavi, the other main opposition leader.The Fars news agency, a semiofficial service linked to the Islamic Revolutionary Guards Corps, indirectly confirmed the protests by saying an unspecified number of demonstrators had been arrested. It called participants “hypocrites, monarchists, ruffians and seditionists” and ridiculed them for not chanting slogans about Egypt, the nominal reason for the protests.
The crackdown came as the protests flared in Yemen and Bahrain. While those outbreaks were reported in some official Iranian state news media, which had also covered the 18-day Egyptian uprising selectively, there was no immediate mention of the clashes in Tehran and elsewhere on such state broadcasters as the English-language Press TV in Tehran.Iran’s Islamic government gradually stamped out the 2009 protests through the shooting of demonstrators, mass trials, torture, lengthy jail sentences and even executions of those taking part.Reports from inside Iran on Monday were harvested from a special Facebook page set up for the day called 25 Bahman, Twitter feeds, telephone calls and opposition Web sites.They indicated that one tactic for sympathizers hoping to avoid a beating at the hands of the police was to drive to the demonstrations, with huge traffic jams reported in Tehran. Security forces on motorcycles tried to run down protesters, witnesses said.Callers to the BBC Persian service television program called “Your Turn” said demonstrators had tried to gather in small knots until the police turned up in force, at which point they would run into traffic to seek refuge with strangers who opened their car doors.“It has not turned into a big demonstration mostly because they never managed to arrive at the main squares,” said Pooneh Ghoddosi, the program’s host.Cellular telephone service was shut off around the main squares and the Internet slowed to a crawl, activists said. Echoing tactics in Egypt and Tunisia, sympathizers outside Iran set up the 25 Bahman Facebook page — named for Monday’s date on the Iranian calendar — to collect videos, eyewitness accounts and any information.Twitter feeds informed demonstrators to gather quickly at a certain intersection, then disperse rapidly. One video showed them burning a government poster as the chant against Ayatollah Khamenei rang out.
The authorities had made no secret of their resolve to stop the demonstrators. “The conspirators are nothing but corpses,” Hossein Hamadani, a top commander of the Revolutionary Guards, said last week in comments published by the official IRNA news agency. “Any incitement will be dealt with severely.”Monday’s clashes erupted as the Turkish president, Abdullah Gul, was in Iran. Speaking at a news conference alongside President Ahmadinejad, he said, “We see that sometimes when the leaders and heads of countries do not pay attention to the nations’ demands, the people themselves take action to achieve their demands.”
A Reuters report said he did not refer directly to Iran. “In this age of communication, in an age where everybody is aware of each other, the demands and desires of the people are very realistic,” he said in a response to a question about events in the Middle East.In Washington, Secretary of State Hillary Rodham Clinton said, “We wish the opposition and the brave people in the streets across cities in Iran the same opportunity that they saw their Egyptian counterparts seize in the last week.”

python - Regex how to use 'or' for string matching - Stack Overflow
I want to parse a web page and find specific patterns using regex on Python.
My Example page have:
<input type="checkbox" name="some name....">
<input type="text", name="somemore name...">
<input type="radio" name="other name...">
And i want to find all matcihng name values of radio and checkbox inputs.
<input type="checkbox" name="(.*?)".*?>
<input type="radio" name="(.*?)".*?>
But i can not figure out how to combine these to regex to a single one?
EDIT: That question might switch to other directions. But it is better for me to tell what i want to do and is my choice of regex usage really suitable for that...
I must query a subscriber and get some basic info about the subscriber and a list of available loans and charges of the sbscriber. RElated module has many scripts that do that kind of job with regex. I also use SGMLparser for some part in my code. But i sometimes see SGML parser fails to parse HTML (did not dig it why it fails but basic reason is unexpected char type errors). So, i must be sure that i van either handle all type of HTML code, or keep on doing this by regex.
CONCLUSION: It is the best choice to use HTMLParser, and using regex is simple a verry bad idea... That is what i get from this question... But since the Question itself is more about regex matcihng then regex usage in thml, i decided to accept the answer abour regex...
python regex share|improve this question edited Sep 10 '12 at 14:17

Just in case you decide to use xml parser, try xml.dom.minidom module, specially getElementsByTagName function and attributes attribute or Attrs method.
<input type="(?:checkbox|radio)" name="(.*?)".*?>
While this works... It is not very robust...
<input type="(checkbox|radio)" name="(?P<name>.*?)".*?>
I've also put a capture group name in there for ease of extraction.
But the old rule applies, don't use regex for parsing html. It's very fragile. What if the code you are parsing changed to be <input class="aha" type="checkbox" name="some name...."> overnight? Use the HTMLParser class or BeautifulSoup.
You should never process HTML with Regex... there are plenty of threads here showing you why. Maybe you can check out this previous SO thread in which various HTML parsers for Python are discussed.

Thank you, but what i need is more complex than i write in here. So that reason and some other reasons, my best choice is using regex.
Trust me. Trust us. Your need is almost certainly not unique. If it is, give us more details in the question (otherwise it may be closed as a duplicate)
May be its quite strict minded, but all job is done in that way up to today :D May be that why i do not want to change the basic structure of the sywstem. What i need to do is, query some subscriber id and get some subscirber info and a list of his loans...
Yes but where is the data coming from? If this is getting data from internal software, you are adding brittleness to the product and incurring technical debt for the company. If it is getting data from outside you are compromising business continuity and opening yourself up to trouble down the road.
Data comes from outside of our system. something like browsing Stackoverflow and checking Questions and returning myself a list of questions i am interested in...

The method includes accepting a digital input signal; amplifying the input signal (Vin); comparing the amplified signal to dc thresholds; measuring output errors; and, calculating the amplifier gain in response to the thresholds. More specifically, accepting a digital input signal includes accepting an input signal having an amplitude. Comparing the amplified signal to dc thresholds includes comparing the amplified signal to a low threshold and a high threshold. Measuring errors includes measuring a predetermined error condition in response to the high threshold and the low threshold. Then, calculating the amplifier gain in response to the thresholds includes calculating the amplifier gain in response to the high threshold, the low threshold, and the input signal amplitude.
We claim: 1. A method for measuring amplifier gain in a digital network, the method comprising:
accepting a digital input signal (Vin) having an amplitude; amplifying the input signal; comparing the amplified signal to a low threshold; comparing the amplified signal to a high threshold; measuring a predetermined error condition in response to the high threshold and the low threshold; and calculating the amplifier gain in response to the high and low thresholds and the input signal amplitude as follows: G=(Vth2−Vth1)Vin. 2. The method of claim 1 further comprising:
measuring the input signal amplitude; and wherein calculating the amplifier gain in response to the high and low thresholds and the input signal amplitude includes calculating the amplifier gain in response to the high threshold, the low threshold, and the measured input signal amplitude. 3. The method of claim 1 wherein accepting a digital input signal includes accepting an input signal with a data pattern; and,
wherein measuring digital output signal errors includes comparing the output of the high and low threshold comparisons to the data pattern. 4. The method of claim 3 wherein measuring digital output signal errors includes measuring a loss-of-lock condition.
5. The method of claim 3 wherein measuring digital output signal errors includes measuring a particular bit error rate (BER).
6. The method of claim 5 wherein measuring digital output signal errors includes measuring a BER selected from the group including 10−3, 10−6, 10−9, and 10−12.
7. The method of claim 3 wherein accepting a digital input signal includes accepting an input signal with a pseudorandom data pattern.
8. The method of claim 3 wherein accepting a digital input signal includes accepting an input signal with a data rate of greater than 10 gigabits per second (Gbs).
9. The method of claim 7 wherein accepting a digital input signal includes accepting an input signal with an amplitude in the range between 5 millivolts (mV) and 1.5 volts, peak to peak.
10. A method for measuring amplifier gain in a digital network, the method comprising:
accepting a digital input signal with an amplitude (Vin); amplifying the input signal; comparing the amplified signal to a low threshold (Vth1); comparing the amplified signal to a high threshold (Vth2); measuring a predetermined error condition in response to the high and low thresholds; and, calculating the amplifier gain as follows G=(Vth2−Vth1)/Vin. 11. A system for measuring amplifier gain in a digital network, the system comprising:
an amplifier having an input to receive a digital input signal (Vin) and an output to supply an amplified signal; a comparator having an input to accept the amplified signal, an input to accept a dc threshold level (Vth), and an output to supply an output signal; a bit error rate (BER) tester having an input to accept the output signal and an output to supply an error rate; and, a gain calculator having an input to receive the threshold level, and input to receive the error rate, and an output to supply an amplifier gain measurement. 12.

This invention generally relates to system gain measurement techniques and, more particularly, to a system and method for measuring amplifier gain in a digital network receiver front-end.
FIG. 1 is a schematic diagram of a conventional digital receiver front-end (prior art). The digital receiver is designed to receive a wide dynamic range input signal. Even if the format of the signal is digital, the wide dynamic range of the input signal gives it characteristics of an analog signal. The purpose of the amplifier is to supply an amplified output signal to an interfacing comparator. If the amplifier gain is too small, the signal may be too small to properly trigger the comparator. Too much gain may result in an amplified signal becoming saturated or distorted, so that it will also be unable to properly trigger the comparator. Either way, improper amplification can result in a bit of information being misinterpreted.
Due to fabrication process tolerances, the exact gain of the amplifier can vary. Therefore, the amplifier gain is monitored. If the signal strength is small, the amplifier gain is increased to optimize the drive level to the interfacing comparator. If the input signal strength is too large, the amplifier gain is minimized to provide the optimal drive to the comparator. However, this approach requires that an integrated circuit (IC) pin be dedicated to monitoring the amplifier output. As the size of ICs decreases, and their functionality increases, it becomes difficult to justify the dedication of a pin to any particular purpose.
Alternately, the receiver front-end may include an automatic gain control (AGC) circuit (not shown). However, AGC circuitry is complicated and can be difficult to calibrate. In other aspects (not shown), the amplifier gain is not monitored, but set assuming a predetermined gain and input signal amplitude. The simplicity of this approach is offset by the degradation of network performance in situations where the actual gain differs from the assumed gain.
It would be advantageous if the gain of a digital receiver front-end amplifier could be determined without having to directly monitor the amplifier output via a dedicated IC pin.
It would be advantageous if the gain of a digital receiver front-end amplifier could be optimized by analyzing the output of the interfacing comparator circuit.
SUMMARY OF THE INVENTION The present invention provides a system and method for determining the gain of a digital receiver front-end amplifier, without having to dedicate an IC pin for directly monitoring the amplifier output. The present invention simplifies the design of a digital receiver network, without degrading receiver sensitivity.
Accordingly, a method is provided for measuring amplifier gain in a digital network. The method comprises: accepting a digital input signal (Vin); amplifying the input signal; comparing the amplified signal to dc thresholds; measuring output errors; and, calculating the amplifier gain in response to the thresholds.
More specifically, accepting a digital input signal includes accepting an input signal having a predetermined (or measured) amplitude. Comparing the amplified signal to dc thresholds includes comparing the amplified signal to a low threshold and a high threshold. Measuring errors includes measuring a predetermined error condition in response to the high threshold and the low threshold. Then, calculating the amplifier gain in response to the thresholds includes calculating the amplifier gain in response to the high threshold, the low threshold, and the input signal amplitude.
Additional details of the above-described method, and a system for measuring amplifier gain in a digital network are provided below.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of a conventional digital receiver front-end (prior art).
FIG. 2 is a schematic block diagram of the present invention system for measuring amplifier gain in a digital network.
FIG. 3 is an exemplary signal diagram of the comparator input signals.
FIG. 4 is a flowchart illustrating the present invention method for measuring amplifier gain in a digital network.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a schematic block diagram of the present invention system for measuring amplifier gain in a digital network. The system 200 comprises an amplifier 202 having an input on line 204 to receive a digital input signal (Vin) and an output on line 206 to supply an amplified signal. Note that although only a single amplifier is shown for simplicity, the present invention system is applicable for use in the measurement of a plurality of amplifiers, or cascaded amplifiers. A comparator 208 has an input on line 206 to accept the amplified signal, an input on line 210 to accept a dc threshold level (Vth), and an output on line 212 to supply an output signal. For example, the comparator supplies a digital high in response to the amplified output signal exceeding the threshold level, and a digital low in response to the amplified signal being less than the threshold level. Typically, the amplifier 202 and comparator 208 are part of a digital receiver 213.
A bit error rate (BER) tester 214 has an input on line 212 to accept the output signal and an output on line 216 to supply an error rate. A gain calculator 218 has an input on line 210 to receive the threshold level, and input on line 216 to receive the error rate, and an output on line 220 to supply an amplifier gain measurement.
In operation, the comparator 208 receives a low threshold (Vth1) on line 210 and the BER tester 214 measures a first error condition in response to the low threshold. Then, the comparator 208 receives a high threshold (Vth2) on line 210 and the BER tester 214 measures the first error condition in response to the high threshold. The gain calculator 218 calculates the amplifier gain in response to the low and high thresholds.
FIG. 3 is an exemplary signal diagram of the comparator input signals. The threshold is initially lowered until a predetermined (first) error condition is obtained, as measured by the BER tester. This threshold level is defined as Vth1. Then, the threshold is increased until the same error condition is obtained. This threshold level is defined as Vth2. The gain calculator also has an input (see FIG. 2) to accept the input signal amplitude measurement. The gain calculator 218 calculates the amplifier gain in response to the high threshold, the low threshold, and the input signal amplitude. As shown in FIG. 2, an assumption is made that the gain calculator performs the input signal amplitude measurement. However, in other aspects of the invention (not shown), additional external circuitry is used to measure the input signal amplitude on line 204 and that measurement is supplied to the gain calculator 218 on an independent line. Note that the threshold determination process may be reversed with the same results, with the high threshold (Vth2) being determined before the low threshold (Vth1)
The gain calculator 218 calculates the amplifier gain as follows:
G=(Vth2−Vth1)Vin. In some aspects of the system, the BER tester 214 has an input on line 204 to accept the input signal. Typically, the input signal follows a pseudorandom data pattern. Then, the BER tester 214 measures the error rate in response to comparing the input signal to the output signal. However, the invention is applicable to any type of information or test pattern. Alternately but not shown, there is no connection of the input signal to the BER tester 214, but the BER tester analyzes a known or predetermined pattern of input signal data against the output signal on line 212. For example, a pattern of alternating ones and zeros can be used.
In some aspects, the BER tester 214 measures a loss-of-lock condition as the first error condition. That is, Vth1 and Vth2 are found in response to the receiver entering a loss-of-lock condition. A loss-of-lock condition occurs in asynchronous communications when the data clock cannot be derived from the incoming data. Alternately, the BER tester 214 measures a particular bit error rate (BER) first error condition. For example, the BER tester can measure a BER such as 10−3 (1�10−3), 10−6, 10−9, or 10−12. However, the present invention system is not limited to any particular first error condition or BER.
The present invention system 200 is of particular interest for amplifier input signals with a data rate greater than 10 gigabits per second (Gbs). Likewise, the amplifier input signal amplitude is typically in the range between 5 millivolts (mV) and 1.5 V, peak to peak. However, the present invention system is not limited to any particular frequencies or signal strengths.
FIG. 4 is a flowchart illustrating the present invention method for measuring amplifier gain in a digital network. It should be understood that some of these steps may be skipped, performed in parallel, or performed without the requirement of maintaining a strict order of sequence.
The method starts at Step 400. Step 402 accepts a digital input signal (Vin). Step 404 amplifies the input signal. Step 406 compares the amplified signal to dc thresholds. Step 408 measures output errors. Step 410 calculates the amplifier gain in response to the thresholds.
In some aspects of the method, comparing the amplified signal to dc thresholds in Step 406 includes substeps. Step 406 a compares the amplified signal to a low threshold. Step 406 b compares the amplified signal to a high threshold. Then, measuring errors in Step 408 includes measuring a predetermined error condition in response to the high threshold and the low threshold. Further, calculating the amplifier gain in response to the thresholds in Step 410 includes calculating the amplifier gain in response to the high and low thresholds.
In other aspects, accepting a digital input signal in Step 402 includes accepting an input signal having a predetermined amplitude. Then, calculating the amplifier gain in Step 410 includes calculating the amplifier gain in response to the high threshold, the low threshold, and the (predetermined) input signal amplitude. Alternately, the input signal strength is not predetermined. Instead, the method includes the additional step of measuring (not shown). Then, calculating the amplifier gain in Step 410 includes calculating the amplifier gain in response to the high threshold, the low threshold, and the (measured) input signal amplitude.
More specifically in some aspects, calculating the amplifier gain in response to the high threshold, the low threshold, and the input signal amplitude in Step 410 includes calculating the gain as follows:
G=(Vth2−Vth1)/Vin. In other aspects of the method, accepting a digital input signal in Step 402 includes accepting an input signal with a data pattern. Then, measuring output errors in Step 408 includes comparing the output of the high and low threshold comparisons to the data pattern. In one instance, Step 408 measures a loss-of-lock condition. Alternately, Step 408 measures a particular bit error rate (BER), such as 10−3, 10−6, 10−9, or 10−12.
In some aspects, accepting a digital input signal in Step 402 includes accepting an input signal with a pseudorandom data pattern. In other aspects, an input signal with a data rate of greater than 10 gigabits per second (Gbs) is accepted. In yet other aspects, Step 402 accepts an input signal with an amplitude in the range between 5 mV and 1.5 V, peak to peak.
A system and method have been provided for measuring amplifier gain in a digital network. An example has been provided has to how the present invention can be applied to a specific problem. However, the invention is not limited to merely the recited example. Other variations and embodiments of the invention will occur to those skilled in the art.

14. The method of claim 13 which comprises the further step of curing the bonding material for at least about four hours at a temperature of at least about 65
After the bonding material is applied, it is permitted to cure at room temperature for at least one hour. The room temperature curing raises the viscosity of the bonding material so that subsequent exposure to a higher temperature in a curing cycle does not causes the bonding material to run off of desired locations. After the initial room temperature curing, the entire fixture 60 and the assembled array 20 are exposed to a temperature of 65 C. is an abnormally long cure for an epoxy bonding material such as the EPO-TEK 301 described hereinabove. However, this inordinately long cure time produces an advantageous hardness in the bonding material which is important in a subsequent finishing operation.

These folks sure give you a great time on these horses. If you have not ridden a horse before, not to worry, these guys will steer you right. The guide was very friendly and spoke great English. You start off with a typical Costa Rican breakfast - yum! We did the full tour which included a stop at a mountain spring fed watering hole (and nearby waterfall). There is a changing room at this site, so wear long pants for the ride and bring a backpack with your bathing suit and towel for the swim. And bring a camera -- plenty of awesome photo ops!

My daughter and I rode with Brisas del Nara on the recommendation of our hotel concierge. It was about a 30 min drive from the MA hotels along a progressively bumpy and small road to get to the ranch. Once there we were served Costa Rican breakfast and good coffee. The horses were quiet and well behaved but not the mindless follower-type horses you sometimes get on a tourist trail ride. Our guide was very friendly and kind to the horses, as were the other staff at the ranch. Saddles were comfortable (as saddles go). The Costa Rican saddle is a bit smaller and more comfortable than a typical Western saddle, I think. The ride was about 2h. We just got into a forest reserve (which I wished I could see more of), then it was time to head back to see the waterfall (which was absolutely beautiful). Although they do advertise change facilities for the swim, they are back at the ranch, so you need to ride out with your swimsuit under your jeans and bring a big towel or sarong to change under or else ride back in a wet swimsuit. I didn't bring a swimsuit and wished I had. Definitely swim the waterfall if you get the chance.

The tour started with them picking us up in a tour van from our villa in Quepos. There was an english speaking guide that rode along and pointed out points of interest and wildlife. They were happy to stop so we could get some good pictures. When we arrived at the ranch we were greeted by the family, and served a great costa rican breakfast. They were very accomodating to our three young grandchildren. We took the half day tour, which was perfect for the kids. We stopped to swim in the river, and our guide and the ranchers grandson swam with us and played with the kids. Our guide told us a lot about the Costa Rican culture, and was very friendly. When we returned to the ranch we were served a delicous lunch of fish, rice, potatoes, and vegetables. The guide sat with us during lunch, and by the time we left he felt like one of the family. I was actually a little sad to say good bye to everyone there.

Sen. Michael Bennet’s cancer surgery was ‘completely successful,’ spokeswoman says - The Washington Post

A spokeswoman for Sen. Michael F. Bennet (D-Colo.), who has been eyeing a White House bid, said Friday that the senator’s surgery last week for prostate cancer was “completely successful” and that he requires no further treatment.
“Michael and his family deeply appreciate the well wishes and support from Coloradans and others across the country, and he looks forward to returning to work after the recess,” spokeswoman Courtney Gidner said in a statement.
Sen. Michael Bennet has an ‘unanticipated hurdle’ in potential 2020 bid: prostate cancer
Bennet, 54, announced his diagnosis two weeks ago and said that if he were cancer-free after his surgery, he would plan to join the growing pool of Democratic presidential hopefuls.
“The work we have in front of us to restore a politics that is worthy of our kids and grandkids has never been more important,” Bennet said in a statement at the time. “This unanticipated hurdle only reinforces how strongly I feel about contributing to the larger conversation about the future of our country.”
