Abstract: Non-idealities of input circuitry of a receiver signal chain can significantly degrade the overall performance of the receiver signal chain. A digital nonlinearity correction (NLC) can be implemented in a receiver signal chain having an ADC. Digital NLC can be designed as a drop in signal preconditioner for existing RF ADC wideband receiver signal chains. A unique equalizer can compensate for a variety of mixer spurs. Accordingly, digital NLC can correct nonlinearities due to mixers and any amplifiers preceding or following the ADC, potentially improving receive chains performance by 15-25 dB. Such a digital NLC solution can be particularly beneficial in defense and instrumentation applications which demand the greatest performance.

Abstract: The battery monitoring techniques described herein may be used for detection of battery anomalies or faults. Also, the battery monitoring techniques described herein may be used to generate estimates of total battery capacity. The battery monitoring techniques may employ an alternating current frequency response (ACFR) of the battery. The ACFR response of the battery may be used to detect anomalies and/or estimate a total capacity of the battery.

Abstract: Modular temperature tracking techniques can be used to estimate internal battery temperatures of battery packs. For example, an electric vehicle can contain a plurality of battery packs. Battery packs of electric vehicles can be composed of several modules each of which may contain multiple batteries in series. A plurality of independent temperature trackers for each cell can be used instead of a single large estimator.
