  • Patent number: 6819225
    Abstract: A novel paging technology allows a group of subscribers to share and take advantage of bargain, promotion, and special pricing information that may otherwise be difficult to obtain or only useful for a very limited time. A service provider collects and stores such information. The information is then compared to a profile for each subscriber detailing what type of information that subscriber is interested in receiving. Information matching the interest profile of each subscriber this then transmitted to that subscriber's pager. Each subscriber's pager may include an input device, such as a virtual keyboard, so that each subscriber can submit information to the system to be shared with other subscribers.

  • Patent number: 6816095
    Abstract: A high speed, high accuracy parallel/serial conversion circuit, wherein a PLL circuit 50 receives as input and locks a clock CLK, and supplies the same to different parts of an apparatus; the PLL circuit 50 controls a 16-tap ring oscillator 60 to shift the phase of a clock frequency-locked to a reference clock so as to generate 32 types of phase shift pulses CK0 to CK31 shifted in phase by increments of {fraction (1/32)} of the clock width from the reference clock by the differential outputs of the 16 taps and supplies the same to a P/S conversion circuit 70; and the P/S conversion circuit 70 generates fine width pulses with {fraction (1/32)} pulse widths based on the 32 types of phase shift pulses shifted in phase by increments of {fraction (1/32)}. Further, the fine width pulses are used to convert parallel signals output from a RAM 30 and a decoder 40 to a serial signal.

  • Patent number: 6813778
    Abstract: A method and system manages and controls the download of programming, i.e., code objects, to a set-top terminal connected to a cable television system so as to prevent disruptions to service that may arise if only some of the objects specified are successfully downloaded and might, therefore, function improperly or conflict with existing applications. When the message to download new or additional code objects lists two or more objects to be acquired, the set-top terminal will only enable and execute downloaded objects if all the listed objects are successfully acquired. If only some of the objects the terminal has been instructed to download are acquired, those downloaded objects may either be purged or stored in memory without being enabled and executed. The system operator may specify in the message instructing the terminal to acquire new objects, whether the listed objects must be implemented as a group or not at all.
