  • Publication number: 20140028111
    Abstract: An improved wireless transmission system for transferring power over a distance. The system includes a transmitter generating a magnetic field and a receiver for inducing a voltage in response to the magnetic field. In some embodiments, the transmitter can include a plurality of transmitter resonators configured to transmit wireless power to the receiver. The transmitter resonators can be disposed on a flexible substrate adapted to conform to a patient. In one embodiment, the polarities of magnetic flux received by the receiver can be measured and communicated to the transmitter, which can adjust polarities of the transmitter resonators to optimize power transfer. Methods of use are also provided.

  • Publication number: 20090218883
    Abstract: A power distribution system comprises a DC bus supplied by an electrical generator and a resistive load connected to the DC bus. A switching device connects to the DC bus and the load and is configured to periodically open the circuit between the resistive load and the DC bus for a reoccurring period of time. The switching device senses the load on the DC bus and changes the length of the period of time based on the sensed voltage.

  • Patent number: 7120480
    Abstract: An apparatus and method for determining if a forward voltage of an LED in a pulse oximeter is within a predetermined range. This is accomplished by measuring the current through the LED, and also by knowing the duty cycle of the pulse width modulator (PWM) drive signal to the LED.
