  • Patent number: 10278231
    Abstract: In an embodiment, a client proxy provides an operating-system-functions (OS-functions) interface to client applications. The client proxy and each of the client applications resides on a wireless transmit/receive unit (WTRU). The client proxy receives, via the OS-functions interface, respective registrations from each of a plurality of the client applications. Each respective registration indicates a respective keep-alive-message signaling rate for the corresponding registered client application. The client proxy determines an optimal signaling rate based on the respective keep-alive message signaling rates indicated by the respective registrations. The client proxy generates proxy keep-alive signaling messages that collectively convey keep-alive-message information on behalf of the registered client applications. The client proxy transmits the generated proxy keep-alive signaling messages to a network node at the determined optimal signaling rate.

  • Patent number: 10277122
    Abstract: A charge pump circuit and a phase-locked loop (PLL) system using the same are provided. The charge pump circuit includes an upper current source, a lower current source and a plurality of switches. The switches are turned on or off by an error signal to increase or decrease the control voltage of the voltage-controlled oscillator (VCO) and further control the frequency of the output signal of the VCO. When the reference frequency signal matches with the divided frequency signal from the VCO, the upper current source and the lower current source are bypassed to decrease the voltage across the MOSFET, thereby minimizes the influence of the leakage current on the control voltage of VCO. In this way, the output jitter can be reduced due to smaller magnitude of peak-to-peak voltage on the control voltage of VCO in the PLL system caused by the leakage current of the MOSFET.

  • Patent number: 10276258
    Abstract: A memory controller includes a clock delay generator, a set of flip-flops, and a control circuit, and is connected to a processor and a memory. The clock delay generator receives a clock signal from the processor, delays the clock signal by a set of delay time intervals, and generates a set of delayed clock signals. The flip-flops receive a test pattern and read data from the memory, sample the test pattern and the read data based on the delayed clock signals, and generate a set of sampled test patterns and a set of sampled read data. The control circuit identifies a sampled test pattern that is equal to the test pattern and the corresponding delayed clock signal as a read clock signal, and outputs the sampled read data that corresponds to the (delayed) read clock signal.

    Abstract: A system and method for identifying a potential parking violation for a location includes storing and rating parking violation related data, and notifying a user, by a computing system communicating with a user's computing device, of the potential parking violation and how to avoid receiving the potential parking violation citation. The data is stored in a database and clustered by data types. The user's computing device is used to identify user type, location, and time. A user engagement panel is used to share and rate parking violation related data and notifications, and rewards are allocated to a user for contributing useful data. Highly rated data may be incorporated into the notifications. The data is analyzed to predict or infer a violation. A notification corresponding to a current location and user type are generated when violations are predicted.
