  • Patent number: 10315037
    Abstract: Devices that communicate using wireless proximal communications measure pulse width to find distortion in the received signal. The distortion may be due to the devices being too close to one another for a transmission power level currently being used which causes ringing of a receiving coil. The distortion may be used to find a correction that the receiving device may use to correct for the distortion in the received pulse train when decoding the pulse train. The distortion may be used to adjust a transmission power level of the receiving device and/or to send an instruction to the transmitting device to adjust the power transmission power level of the transmitting device. The distortion may be used for other purposes including determining a device depth and/or location for an implanted device, such as an implantable medical device within a body of a patient.

  • Patent number: 3976213
    Abstract: A loader for elevating a boat and shifting it over the top of a vehicle to a stowed position is disclosed. The loader includes a first load supporting frame attachable to the vehicle and includes an upright frame member, a winch and a pulley at its upper end through which a cable extends. A second load supporting frame has a wheeled dolly at one end attachable to the stern of the boat and means to pivotally connect it to the first load supporting member. The cable extends from the pulley through releasable cable guide means and is attached adjacent the stern of the boat so that reeling in of the cable causes the stern of the boat and second frame to move toward the first frame where it is attached and the cable removed from the guide means and continued reeling in of the cable lifts the stern upwardly and slides the boat to the stowed position. Other features are disclosed.
