  • Low jitter clock recovery circuit
    Patent number: 8995598
    Abstract: A clock recovery circuit includes a first phase detector for measuring the phase difference between a first clock signal from a voltage controlled oscillator (VCO) and a data signal. A phase shifter responsive to a control signal based on this phase difference adjusts the phase of an incoming clock signal to yield a second clock signal. The phase difference between the first clock signal and the second clock signal is measured and the resulting signal is low-pass filtered to derive a control signal for controlling the VCO. The phase locked loop including the VCO filters out jitter.

  • IPv6-over-IPv4 architecture
    Patent number: 8976963
    Abstract: Mobile clients can execute IPv6 applications in an IPv4 environment without the need for any specialized IPv6 hardware or upgrades to the network infrastructure. The architecture provides a seamless, disruption-free connectivity experience for mobile clients. Mobile clients are automatically connected to other mobile clients irrespective of their network connectively, whether wireless, wire line, IPv4, IPv6, public or private. Mobile clients communicate with other mobile clients using a secure, end-to-end IPv6 tunnel. This creates a persistent VPN connection between two clients using software.

  • Frequency responsive bus coding
    Patent number: 8498344
    Abstract: A data system 102 permits bus encoding based on frequency of the bus; an encoding scheme may be implemented to avoid undesirable frequency conditions such as a resonant condition that may lead to degradation in system performance. The device or integrated circuit will typically include an encoder; in one embodiment, the encoder is a data bus inversion (DBI) circuit that selectively inverts all lines of a data bus. A detector that may include a band-pass or stop-band filter that, for example, evaluates data for transmission on the bus to detect frequency, for example, a predetermined frequency or a frequency range. The detector provides a control signal for the encoder to selectively apply an encoding scheme as a function of frequency.

  • Planetary arrangement of motors, masses around a axis of a flywheel
    Publication number: 20130174691
    Abstract: A powered binary masses flywheel assembly device that will extract gravitational energy and store it together with the energy inputted externally into the flywheel in the form of rotational kinetic energy while rotating in the substantially vertically plane. The device can be used as part of a drive motor assembly to power machinery or as an electrical generator assembly. The binary masses arrangement in the flywheel enables the system to rotate at ever higher rpm using less power input per revolution the higher the rpm. This phenomenon starts to take place when the kinetic energy being stored in the rotating flywheel disc is exceeded by the kinetic energy stored in the binary masses attached to the flywheel disc which form the flywheel assembly.
