Abstract: An anti-theft system that is capable of being tracked by and automatically notifies the appropriate authorities when leaving a designated geo-fence area. The anti-theft system includes a storage device having two opaque housing portions that can be secured together along their respective peripheries, providing a cavity. The housing portions are opaque except for a cutout in one of the housing portions. The cavity provides a GPS and a mounting display, wherein the mounting display secure a valuable so that it is partially visible through the cutout, while the GPS is not so visible. The GPS tracks and notifies according to predetermined criteria.

Abstract: A radio frequency (RF) system including: a modem configured to generate a first set of digital bits and to create an analog RF signal from those digital bits; a power amplifier configured to receive the analog RF signal and to amplify the analog RF signal, the power amplifier including an input for a biasing voltage; a feedback loop configured to sample an output of the power amplifier, generate a second set of digital bits corresponding to the first set of digital bits, digitally process the second set of digital bits to determine a linearity characteristic of the power amplifier, and to adjust the biasing voltage in response to determining the linearity characteristic.
