Abstract: A radar system includes a hybrid-power amplifier and a power control unit coupled to the hybrid-power amplifier. The power control unit is configured to control the amplification of a chirp signal output by the radar system based upon an assessment of an interchirp time provided by a chirp profile. The interchirp time is a time difference between a first chirp signal and a second chirp signal that are to be output by the hybrid-power amplifier. When the power control unit determines that the interchirp time is less than an interchirp time threshold, a fast-power loop control configuration is used to control the transmitted output power at hybrid amplifier level. When the power control unit determines that the interchirp time is equal to or greater than the interchirp time threshold, a slow-power loop configuration or a combination of the slow-loop configuration and the fast-loop configuration is used to control the transmitted output power at the hybrid-power amplifier.

Abstract: A security platform includes a security tag having a wireless communication circuitry configured to receive a user identification (ID) from an ID tag. After receiving the user ID, the security tag tracks the distance the security tag moves away from a predetermined point. The security tag then compares the determined distance to a predetermined distance threshold to determine whether the security tag is within a range. In response to the determined distance being greater than the predetermined distance threshold, the security tag determines that the security tag is outside of the range and activates an alarm. The alarm of the security tag continues to be active until a second user ID having appropriate access rights is received.
