A frequency management scheme for a hybrid communications/positioning device, such as a cellular/GPS or other combined device, generates a local clock signal for the communications portion of the device, using a crystal oscillator or other part. The oscillator output may be delivered to a phase locked loop to drive a high-frequency clock for the cellular or other communications portion of the hybrid device. A processor may determine frequency error between the phase locked loop and base station or other reference, to derive a digital frequency tracking message. A Doppler search or other logical control message may likewise be communicated from the processor to a GPS or other positioning receiver. The GPS receiver circuitry may consequently adjust Doppler center, window width or other parameters to enhance time to first fix or other performance. The architecture eliminates the need for a second crystal or other direct oscillator in the GPS receiver portion of the hybrid device, while still maintaining GPS performance. The architecture of the design also eliminates the need for frequency correcting elements in the crystal oscillator or other base reference oscillator or clock. The invention can furthermore be used in any system, radio, modem, transceiver, or receiver that has two or more receivers that share one reference or base oscillator or clock.

This application describes a revolutionary device to help prevent the development of pressure ulcers. The device works by using a small number of sensors in the wheelchair or bed to determine and track the projection of the patient's center of gravity (COP) onto the plane of the chair or bed. The sensor data are processed by various algorithms which determine when the danger of pressure ulcer development arises and alerts an attendant to reposition the patient. The repositioning is likewise monitored, and if it is inadequate, a higher-level alarm is issued. This device also maintains a history of patient position and movement, which is potentially useful for diagnostic purposes, such as tracking the degree of improvement resulting from a course of treatment or therapy. The archival record can also provide verification of proper care in the event of lawsuits or insurance claims. Operation of the device is non-intrusive and does not disturb either the patient or the caregiver unless repositioning of the patient is needed. The invention is based on simple, fundamental principles of physics and engineering. It is implemented with a few force sensors, microprocessors, and wireless networking technology—all of which are readily available. The unique attributes of this apparatus are: Real time performance coupled with maintenance of an archival history. Inexpensive hardware platform. Fully self-contained apparatus. Flexible algorithms for processing the sensor data and tracking motion trajectories in a quantitative manner. The hardware portion of the apparatus may adapted to be placed in the wheelchair or bed under the normal cushions, for mobility-impair patients, or it may be used as a force platform, much like a bathroom scale, for standing stability monitoring or gait training. It transmits the instantaneous COP position information over a wired or wireless network to a processing and monitoring station. It does not employ any external components such as video cameras, local GPS transmitters, etc. Aside from a tool for prevention of pressure in mobility-impaired patients, various embodiments of this system has applications in physical and occupational therapy, gait training, mental training (biofeedback), sports and athletic training, (e.g., golf swing training, baseball batting practice), gymnastics, yoga, dance/ballet, sports paraphernalia design, and a host of other areas, etc.
