Abstract: A body armor assembly includes a plurality of rigid tiles that are supported in a manner to provide movement and flexibility while still providing the protection of rigid armor. In a disclosed example, a tile holder maintains a plurality of tiles in a selected alignment. The tile holder maintains a minimum overlap dimension between adjacent tiles. Some of the tiles are maintained by the tile holder in a manner that allows for the overlap dimension to increase beyond the minimum overlap dimension. In a disclosed example, at least two rigid layers have at least one ballistic material layer between them to provide a rigid armor material composition.

Abstract: A compact field programmable gate array (FPGA)-based digital motor controller (102), a method, and a design structure are provided. The compact FPGA-based digital motor controller (102) includes a sensor interface (206) configured to receive sensor data from one or more sensors (104) and generate conditioned sensor data. The one or more sensors (104) provide position information for a DC brushless motor (108). The compact FPGA-based digital motor controller (102) also includes a commutation control (210) configured to create switching commands to control commutation for the DC brushless motor (108). The commutation control (210) generates commutation pulses from the conditioned sensor data of the sensor interface (206). The compact FPGA-based digital motor controller (102) also includes a time inverter (208) configured to receive the commutation pulses.
