  • Method and apparatus for detecting loss and location of a portable communications device
    Publication number: 20050046580
    Abstract: A portable communication device (10) includes a transceiver (12 and 14), an acceleration sensor (20) coupled to the transceiver, and a processor (16) coupled to the acceleration sensor. The processor is programmed to monitor (32) an acceleration profile of the portable communication device and compare (48 and 52) the acceleration profile of the portable communication device with at least one pre-stored acceleration profile (18).

  • Knee laxity measurement
    Publication number: 20040260208
    Abstract: A device for measuring a varus rotation angle in a knee comprises a femoral reference member configured to be positioned medially of the knee, a first arm hingedly engaged to the femoral reference member, and a first potentiometer to output an angular relationship between the femoral reference member and the first arm. The device also includes a second arm hingedly engaged to the first arm, and a second potentiometer to output an angular relationship between the first and second arms, wherein the varus rotation angle is determinable from the outputs of the first and second potentiometers. Furthermore, a joint-space opening of the knee joint may be determined using the outputs of the first and second potentiometers.
