  • Determining a characteristic of atomic particles affecting a programmable logic device
    Patent number: 7763861
    Abstract: Methods and systems are provided for determining a characteristic of an atomic particle affecting a programmable logic device (PLD). The PLD is configured to generate a value at one or more outputs. A source generates a packet of atomic particles. The departure from the source is indicated for the packet of the atomic particles. The PLD is impacted with the packet of the atomic particles. A change is detected in the value of one or more outputs of the PLD. The change in the value of the output or outputs is a result of the impact of the PLD by one of the atomic particles from the packet. A time interval is determined between the departure of the packet of the atomic particles from the source and the change in the value of the output or outputs.

  • Phase shift keying signaling for integrated circuits
    Patent number: 7512188
    Abstract: The present invention relates to a system for communicating between two integrated circuits (ICs) or within an IC. The ICs are either on the same circuit boards or on different circuit boards with a common backplane. The system comprises a first integrated circuit having an output circuit for generating phase shift keying signals and a second integrated circuit having an input circuit for decoding the phase shift keying signals. The output circuit may include a ring oscillator for generating multiple clock signals that are phase-locked to one another.

  • Frequency shift keying signaling for integrated circuits
    Patent number: 7349488
    Abstract: The present invention relates to a system for communicating between two integrated circuits (ICs) or within an IC. The ICs are either on the same circuit boards or on different circuit boards with a common backplane. A first integrated circuit has transmitter circuit that generates frequency shift keying signals using digital data and a second integrated circuit has a receiver circuit for recovering the digital data from the frequency shift keying signals.

  • Method and circuit for controlling an antenna system
    Patent number: 7088288
    Abstract: A method of controlling an antenna system of a wireless communication network having a plurality of cells is disclosed. The method comprises the steps of determining antenna weights to enable communication between a wireless communication network and the wireless communication device within the wireless communication network; storing the antenna weights in a programmable memory associated with the wireless communication network; and providing predetermined stored antenna weights to the antenna system based upon a location of the wireless communication device. A circuit and wireless communication network for controlling an antenna system are also disclosed.
