  • Patent number: 11899696
    Abstract: The technology disclosed relates to systems and methods for generating a multi-part place identifier with at least one part. The system includes logic to receive a location address and a place name wherein the location address is a validated address. The system includes logic to calculate a geocode for the location address and use the geocode to identify a geometrical boundary encompassing the location address. The system includes logic to convert the identified geometrical boundary to an alpha-numeric identifier forming a Where part of the multi-part place identifier. The system can use an input location address or a place name to match a previously generated and stored multi-part place identifier. The system can provide the generated or matched multi-part place identifier to a user for use in further analysis.

  • Patent number: 11762914
    Abstract: The technology disclosed relates to systems and methods for finding a multi-part place identifier with at least one part. The system includes logic to receive an input including an input location address and validate the input location address (e.g., using coding accuracy support system or CASS). The system includes logic to access a database storing records of validated addresses and corresponding multi-part place identifiers using the validated address. The system includes logic to match the validated input address to an address in the stored records in the database and retrieve corresponding matched multi-part place identifier with at least a Where part. The Where part includes an alpha numeric identifier indicating a geometrical boundary for the matched validated input address. The system can provide the matched multi-part place identifier with at least the Where part to a user for use in further analysis.

  • Patent number: 11184418
    Abstract: Technologies are described herein for event delivery and stream processing utilizing virtual processing agents. Upon receiving an event publication in a queue, a runtime system identifies one or more virtual processing agents that might be interested in, but have not explicitly subscribed to, the published event. Event information of the published event is then delivered to the identified virtual processing agents. Prior to the actual delivery, the runtime system further determines if the virtual processing agents have been activated and activates those processing agents that have not been activated. Based on the received event information, some of the virtual processing agents might decide to explicitly submit subscriptions to receive more events from the queue. The explicit subscriptions will trigger the runtime system to deliver the subscribed events to the processing agents, which might include past events that have been published in the queue before the explicit subscription is received.

  • Patent number: 8863028
    Abstract: A motion desktop, including a moving image, may be presented on a display screen of a processing device. Foreground items such as, for example, icons and associated text, or other information, may appear on a surface of the motion desktop. In embodiments consistent with the subject matter of this disclosure, foreground content may be rendered to a composing surface, which may be an alpha-enabled surface capable of presenting translucent items. A motion desktop module may render content for at least a portion of a background of the motion desktop to a respective shared memory, shared with a composer. The composer may periodically copy the rendered content from the shared memory to the composing surface, where the composer may compose and blend a scene from background and foreground content. The composed scene may then be presented as the motion desktop.

  • Patent number: 6958648
    Abstract: A programable gain amplifier (PGA) has an amplifier and a variable resistor that is connected to the output of the amplifier. The variable resistor includes a resistor that is connected to a reference voltage and multiple parallel taps that tap off the resistor. A two-stage switch network having fine stage switches and coarse stage switches connects the resistor taps to an output node of the PGA. The taps and corresponding fine stage switches are arranged into two or more groups, where each group has n-number of fine stage switches and corresponding taps. One terminal of each fine stage switch is connected to the corresponding resistor tap, and the other terminal is connected to an output terminal for the corresponding group. The coarse stage switches select from among the groups of fine stage switches, and connect to the output of the PGA.

  • Patent number: 6791379
    Abstract: A low jitter, high phase resolution phase lock loop incorporating a ring oscillator-type VCO is designed and constructed to operate at a characteristic frequency M times higher than a required output clock frequency. Multi-phase output signals are taken from the VCO and selected through a Gray code MUX, prior to being divided down to the output clock frequency by a divide-by-M frequency divider circuit. Operating the VCO at frequencies in excess of the output clock frequency, allows jitter to be averaged across a timing cycle M and further allows a reduction in the number of output phase taps, by a scale factor M, without reducing the phase resolution or granularity of the output signal.
