  • Publication number: 20210083522
    Abstract: A system and method of controlling inductive power transfer in an inductive power transfer system and a method for designing an inductive power transfer system with power accounting. The method of controlling inductive power transfer including measuring a characteristic of input power, a characteristic of power in the tank circuit, and receiving information from a secondary device. Estimating power consumption based on the measured characteristic of tank circuit power and received information and comparing the measured characteristic of input power, the information from the secondary device, and the estimated power consumption to determine there is an unacceptable power loss. The method for designing an inductive power transfer system with power accounting including changing the distance between a primary side and a secondary side and changing a load of the secondary side.

  • Patent number: 10862335
    Abstract: A system and method of controlling inductive power transfer in an inductive power transfer system with power accounting. Parasitic metal in proximity to the primary unit can be more accurately detected by accounting for changes in known power losses during operation. The amount of power loss during inductive power supply transfer in an inductive power supply system can vary depending on the alignment of the primary unit and the secondary device. The amount of power loss during inductive power supply transfer can also vary as a function of changes in the operating frequency of the switching circuit in the primary unit or as a function of changes in the secondary device load.

  • Patent number: 9154002
    Abstract: A wireless power supply system that detects communications in the input power to the switching circuit. In this aspect of the invention, the wireless power supply includes a detector for generating a signal indicative of the current in the input to the switching circuitry, a band-pass filter for filtering the detected signal, an amplifier for amplifying the filtered signal, a filter for filtering the amplified signal and a comparator for converting the final signal into a stream of high and low signals that can be passed to a controller for processing as binary data stream.

  • Patent number: 9106269
    Abstract: A wireless power transfer system with a remote device having a communication transmitter configured to initiate communications with a framing pulse to prevent noise from being mistaken for legitimate data. The communication system may employ a bi-phase modulation scheme, and the framing pulse may be generated to present no transitions in the communication signal during a specified period of time. The communication transmitter may produce the framing pulse by applying a load in the remote device. The present invention also provides a method for transmitting communication signals in a wireless power supply system including the general steps of: (a) preceding each communication with a framing pulse configured to present a bit sequence that does not exist in legitimate data communications, (b) maintaining the framing pulse for a period of time sufficient to effectively “reset” the communications receiver and (c) transmitting communications following the framing pulse.

  • Patent number: 8259428
    Abstract: A voltage clamp protection circuit to protect against overvoltage conditions where there is insufficient current to blow a fuse. The voltage clamp protection circuit includes a voltage clamp and a thermal cutoff. The voltage clamp clamps any overvoltage to a clamping voltage. If an overvoltage condition persists for too long the voltage clamp dissipates a sufficient amount of heat to activate the thermal cutoff creating an open circuit that protects the rest of the circuit. The voltage clamp protection circuit may be used in combination with a variety of other protection circuits to provide increased protection.

  • Patent number: 5600539
    Abstract: A drawer slide which is capable of moving in and out of the housing of a computer or other electronic apparatus is configured to receive an interface card which is connected into the circuitry of the computer when the drawer slide is in a fully inserted position. The drawer slide rides in a drawer guide which is secured to the computer structure. An interface connector is mounted on the drawer guide and engages a connector on the interface card for connecting the interface card to the remainder of the computer circuitry. A key lock mechanism prevents unauthorized movement of the drawer slide and the associated interface card out of the computer housing.

  • Patent number: 5294784
    Abstract: An apparatus which is a single portable device for scanning and downloading data. The apparatus employs a laser within an optical scanner to accomplish both scanning and downloading functions. In addition to the optical scanner, the apparatus employs control and communication circuitry for switching from scanning to downloading and for modulating an outgoing laser beam during downloading. A modulating material, such as a liquid crystal display or electrochromic lens, is excited to modulate the outgoing laser beam passing through it. The optical scanner also includes a motor-driven mirrored spinner which may be stopped to accomplish a high rate of data transfer during downloading using a highly directional beam.
