Abstract: Technology for a biometric identification system is described. The biometric identification system can include an infrared (IR) illumination device, a thermal imager, and a controller. The controller can determine, using a defined thermal profile, when a thermal image captured by the thermal imager includes a face of a user. The controller can determine, based on the thermal image, when the face of the user is located within a selected range of distances from the thermal imager. The controller can instruct the IR illumination device to illuminate for a selected period of time when the face of the user is located within the selected range of distances from the thermal imager.

Abstract: Embodiments of methods and means for passively emulating channels in a multiple-input multiple output (MIMO) system are provided. Such embodiments include passively splitting a plurality of radio frequency signals into a greater plurality of such signals. Each of the greater plurality of radio frequency signals can then be selectively and passively attenuated, delayed and/or phase shifted. The resulting modified radio frequency signals are then recombined crossed over channels and coupled to a plurality of output nodes. Economical and versatile device and system testing is thus facilitated in a low-noise radio frequency environment without the need for complex up/down frequency or analog/digital conversions.

Abstract: A method of adjusting a power amplifier may include producing a power measure of an output signal of the power amplifier and estimating an estimated transmission error of the output signal from the power measure. The estimated transmission error may be compared with a maximum error that is associated with a data rate of the output signal. A bias voltage that is input to the power amplifier may be decreased if the comparing determines that the estimated transmission error is less than the maximum error.

Abstract: A high power, low loss RF strip transmission line coupling structure is provided. It includes a multi-layer printed circuit board (PCB), a top cover and a bottom cover. The top and bottom covers provide the ground reference for the strip transmission line coupling structure. The PCB is fastened to the top and bottom covers and is used for: creating the center conductor of an air dielectric strip transmission line and edge coupler; providing a means to transition from microstrip to air dielectric strip transmission line; supporting the air dielectric strip transmission line; routing of other signals; and passing ground to the top and bottom covers. To create an air dielectric strip transmission line, the PCB material is adequately removed to effectively form a rectangular bar of dielectric and metal layers. This rectangular bar is plated along the edges where the PCB material was removed to ensure that the top and bottom PCB metal layers are at the same potential.
