  • Publication number: 20120163345
    Abstract: Methods and apparatus enabling seamless vertical handover between radio networks. In one embodiment, a mobile device in communication with multiple networks, scans the networks for suitable candidate networks for handover. If the mobile device experiences signal loss below a first threshold, the mobile device primes itself for a handover. Once the signal loss drops below a second threshold, the mobile device executes the handover. The priming of the device enables very low level hardware to detect and initiate the handover (rather than higher layer software). Consequently, software applications data loss is greatly improved (i.e., reduced) during a vertical handover.

  • Patent number: 7231227
    Abstract: A multi-mode receiver and methods are provided, which use blind source separation (BSS) analysis to distinguish the various wireless communication signals from each other. Specifically, different signal types can be identified by BSS. The different signal types can be in overlapping frequencies or they can be in completely different frequencies. The BSS analysis may use center or carrier frequency, bandwidth, modulation scheme, access scheme, or wireless communication resources as an input to assist in the BSS.

  • Patent number: 7221243
    Abstract: An apparatus and method are presented for combining electrical signals. The apparatus includes a phase-shift distributed element with an input to accept a first signal and an output to supply the first signal with a phase-shift; and a filter with a first signal port connected to the phase-shift element output, a second signal port to accept a second signal, and a third signal port to supply combined and filtered first and second signals. The phase-shift element has a signal path with a predetermined length and the phase-shift element output supplies the first signal with a phase angle shift responsive to the length of the signal path. In one example, the phase-shift element is formed from monoblock and coaxial elements, either singly or in combination, and is a tank circuit resonator in the filter.

  • Patent number: 7085585
    Abstract: A system and a method are provided for vibrating a portable device. The system includes a vibrator housing with stops, a vibrator circuit, and a controller. The controller has an output to supply alternating electric current. The vibrator circuit includes a vibrator coil and a magnetic vibrator rod. The vibrator coil is made of a conductive material and has an inside core space and inputs to accept the alternating electric current. The vibrator coil generates an alternating magnetic field through the core space in response to the alternating electric current and the vibrator rod moves in a reciprocating linear fashion in the core space in response to the alternating magnetic field. The vibrator rod has ends with audio damping pads impacting against stops in the vibrator housing. The vibrator housing vibrates in response to the vibrator rod impacting against the stops.

  • Patent number: 6208202
    Abstract: A power amplifier circuit arrangement including a driver amplifier, a switch, an amplifier path having a band pass filter and a power amplifier, and a bypass path which bypasses the power amplifier when excess gain and output power are not needed. When an RF-analog signal from the driver amplifier is switched to the amplifier path, the signal is band-pass filtered and amplified. Then the signal is split into an in-phase and a quadrature signal. Either the in-phase or the quadrature signal is inverted and summed with the other of the in-phase or quadrature signal, and the summed signal is transmitted to an output port. When the RF-signal from the driver amplified is switched to the bypass path, the power amplifier is turned off and the bypass path directs the signal to the output of the power amplifier, which appears as a high impedance to the signal. The signal reflects off the power amplifier to the output port.

  • Patent number: 6060949
    Abstract: A power amplifier circuit arrangement including a power amplifier, and a bypass network for bypassing an RF-input signal around the power amplifier when excess gain and output power are not needed. When the bypass network is used, the power amplifier is turned off. A circulator connects the bypass network to the power amplifier output, thus removing the requirement of an output switch. The RF-input signal enters the circulator which routes the signal toward the output of the power amplifier. Because the amplifier is off, its output appears as a high impedance and reflects the signal back to the circulator. The circulator routes the reflected signal the signal output.

  • Patent number: 5974041
    Abstract: An amplifier circuit for providing an amplified signal in response to an input signal. The amplifier circuit includes an input network for applying the input signal to a selected at least one of a plurality of amplifier stages. An output network is provided for coupling the amplified signal from the selected at least one amplifier stage. The appropriate amplifier stage is selected by a control circuit in response to a desired power value of the amplified signal. By selectively activating only the amplifier stage(s) that are necessary to provide the desired level of output power, increased DC efficiency can be accomplished in applications that require an amplifier which operates linearly over a wide dynamic range.
