The present invention pertains to antibodies against a novel isoform of human PD1 protein (&#x394;42PD1) that contains a 42-nucleotide in-frame deletion in exon 2. The invention also pertains to methods of using the antibodies against &#x394;42PD1 for the treatment for autoimmune disorders. In certain embodiments, the antibodies against &#x394;42PD1 are monoclonal.

Antibodies against novel PD1 isoforms and uses thereof

A wireless charging receiver as described herein includes a configurable rectifier configured to convert an alternating current input to a direct current output in a single processing stage, wherein the configurable rectifier comprises one or more diodes, and a controller communicatively coupled to the one or more diodes and configured to select one of a plurality of mode cycling schemes and control a present operating mode of the active diodes according to a selected mode cycling scheme. Additionally, an active diode as described herein includes a comparator, a gate driver, a power transistor, and a delay compensation circuit for compensation of at least one of a turn-on delay and a turn-off delay of the active diode, the delay compensation circuit including analog feedback loops.

Wireless charging receiver

A differential difference amplifier Type-III compensator of a voltage-mode switching converter can be designed to help regulate an input voltage from a power source. A voltage-mode switching converter can comprise a power stage and a voltage-mode controller. A voltage-mode controller can comprise a compensator, which comprises a differential difference amplifier. The design of the differential difference amplifier Type-III compensator can reduce production costs and enhance power transfer efficiencies.
