  • Harness with Integral Relief Loops for Suspension Trauma
    Publication number: 20150060195
    Abstract: A safety harness (10) is provided to be worn by a person and to allow the person to manipulate the harness (10) to alleviate the potential effects of orthostatic intolerance in the person while suspended by the harness (10). The harness (10) includes one or more hand engageable members (102) allow the person to selectively repositioning a strap (70, 80, 90) of the harness (10) from a first position where the strap (70, 80, 90) extends across an upper portion of a lower torso of the person and a second position where the strap (70, 80, 90) extends across a lower portion of the lower torso of the person.

  • Battery life extending technique for mobile wireless applications using bias level control
    Patent number: 7505742
    Abstract: An operating voltage applied to a transmitter's power amplifier in a mobile wireless transceiver is dynamically controlled so as to improve the efficiency of the transmitter at all output power levels. In one embodiment, the bias current levels within the transmitter are also varied to optimize the efficiency of the transmitter at all output power levels. In a preferred embodiment, a highly efficient switching regulator is controlled by a control circuit to adjust the operating voltage and/or bias current for the power amplifier in the transmitter. The control circuit has as its input any of a variety of signals which reflect the actual output power of the transmitter, the desired output power, or the output voltage swing of the transmitter.
