Abstract: The present disclosure relates to circuits, systems, and methods of operation for a memory device. In an example, a memory device includes a memory array including a plurality of memory cells, each memory cell having an impedance that varies in accordance with a respective data value stored therein; and a tracking memory cell having an impedance based on a tracking data value stored therein; and a read circuit coupled to the memory array, the read circuit configured to determine an impedance of a selected memory cells with respect to the impedance of the tracking memory cell; read a data value stored within the selected memory cell based upon a voltage change of a signal node voltage corresponding to the impedance of the selected memory cell.

Abstract: A locator beacon device for use with flying sport discs includes an over-molded housing that encloses a substrate, such as a printed circuit board (PCB) on which is mounted a computer-based processor, e.g., a microcontroller that is configured to control a sound generating device. The device is configured with a height that is less than the depth of an annular rim that extends from the circumferential edge of the disc.

Abstract: A lighting system for sports equipment is disclosed that includes one or more color-emitting light sources, which can be, for example, red-green-blue light-emitting diodes or flexible video displays, and a computer-based controller configured to vary emissions of said light sources. The sports equipment may be a snow board, snow skis, a skate board, water skis, and a wake board.
