  • Publication number: 20190133493
    Abstract: A method for analyzing gait is provided for a system including multiple accelerometers. The method includes: for each time point and each accelerometer, calculating a root mean square (RMS) value according to the accelerations sensed on sensing axes of the corresponding accelerometer; calculating a cross correlation coefficient according to the RMS values of a first accelerometer and a second accelerometer; calculating a first auto-correlation coefficient of the RMS values of the first accelerometer; calculating a second auto-correlation coefficient of the RMS values of the second accelerometer; and calculating a first gait index according to the cross correlation coefficient, the first auto-correlation coefficient, and the second auto-correlation coefficient.

  • Patent number: 7444451
    Abstract: The present invention relates to an adaptive interrupts coalescing system with recognizing minimum delay packets. The adaptive interrupts coalescing system of the invention comprises a first calculating device, a packet header parser, a second calculating device, and an interrupt controller. The first calculating device is used for calculating packet information of a plurality of packets. The packet header parser is used for recognizing the type of service field in each packet and for generating a minimum delay control signal. The second calculating device is used for determining a coalescing interrupt number signal according to the packet information and the minimum delay control signal. The interrupt controller is used for transmitting an interrupt control signal to process the packet according to the coalescing interrupt number signal.

  • Patent number: 7174374
    Abstract: The present invention discloses a multi-priority media access control method for a multi-channel slotted ring network. In the slotted ring networks, each node has one tunable transmitter and one fixed receiver for data channels, and is able to inspect slot status on all channels. The header slot format defines the slot priorities on ring networks and limits which packets can be transmitted through the slots. By assigning slot priority based on two thresholds to raise and lower slot priority, multiple priority packets can be transmitted.
