cavity structure increases light transmittance, however, layer structure of the existing microcavity structure is complicated and it is required to manufacture microcavity structures with different thicknesses for regions corresponding to color filters of each color so that the manufacturing process is complicated. 1. Field of the Invention
This invention relates to cellular communications and specifically to frequency calibration in cellular devices.
2. Background
Cellular systems typically have a stringent frequency requirement to enable them to provide a very accurate frequency reference to radio systems.
Previous cellular devices experience frequency shifts when internal signals are turned on or off. These frequency shifts interfere with optimal operation of the cellular devices.
What is needed are methods and systems for enabling a cellular device to continue to operate at an optimal frequency when internal signals experience a change in power.
Features and advantages of the present invention will become more apparent from the detailed description set forth below when taken in conjunction with the drawings, in which like reference characters identify corresponding elements throughout. In the drawings, like reference numbers generally indicate identical, functionally similar, and/or structurally similar elements. The drawing in which an element first appears is indicated by the leftmost digit(s) in the corresponding reference number. Vehicle instrument panels typically include numerous switches, such as variable potentiometers, which are inserted through apertures formed in the instrument panel and are electrically connected for providing various electrical operations in the vehicle, such as instrument panel light dimming, heating ventilation and air conditioning (HVAC) control, etc. These switches typically include a metal spring installed with the switch which engages the rear surface of the instrument panel for retaining the switch in the instrument panel aperture. Typically, the switch assemblies are installed in the vehicle by hand, therefore low insertion forces are required. Additionally, electrical connectors are subsequently attached to the rear of the switch assembly once it has been installed in the instrument panel aperture, therefore high retention forces are required to prevent inadvertent removal during such subsequent attachment. For example, typically at least approximately 80 Newtons of minimum push-out force is required to prevent unwanted detachment of the switch assembly from the instrument panel aperture. An additional requirement for such switch assemblies is that they must be removable for servicing.
A problem with the metal springs referenced above is that they add cost by requiring the manufacture, handling and assembly of such spring components.
Accordingly, it is desirable to eliminate the metal spring from the assembly to reduce cost while maintaining low insertion forces and high retention forces.
