  • Patent number: 9712368
    Abstract: A chip-to-chip communications circuit which is particularly well-suited for short range communication (less than a few inches) from one integrated circuit (chip) to another is presented. The circuits preferably utilize multi-frequency quadrature amplitude modulation (QAM) mechanisms for converting digital data bits from a parallel form into a serial analog stream for communication over a chip I/O connection. Differential current mode modulation in the transmitter, and demodulation in the receiver, are utilized which reduce latency and power-consumption while increasing manufacturing yields and resilience to process variations.

  • Publication number: 20170189773
    Abstract: A ball-returning net comprises a vertical wire frame, a vertical net, a floor wire frame, a slope net, two side barrier nets, and a detachable strap. The vertical net is fixed to the edge portion of the vertical wire frame and blocking the opening of the vertical wire frame. The slope net is disposed over the floor wire frame so as to be tilted from an elevated lower portion of the vertical net to a front edge portion of the floor wire frame, so as to be configured that a ball hitting the vertical net falls down on the slope net and rolls down in a direction of the front edge portion of the floor wire frame. The detachable strap holds the slope net and the vertical wire frame tightly, bending a rear portion of the slope net in a V shape.
