  • Patent number: 7409702
    Abstract: A method of identifying programs in a digital video communication system, consistent with certain embodiment of the present invention involve generating an auxiliary program association table (PAT) and an auxiliary program map table (PMT), wherein the auxiliary PAT and auxiliary PMT relate at least one program identifier (PID) to a program. The auxiliary PAT and auxiliary PMT are packetized and identified using a designated PID. The designated PID is encoded as private descriptor in a network information table (NIT) that is transmitted to the Set-top boxes (STB) over an out of band channel. The STBs have an out of band modem that receives a network information table (NIT). A NIT parser parses the NIT to obtain a designated program identifier (PID) for packets containing an auxiliary program association table (PAT) and an auxiliary program map table (PMT).

  • Patent number: 7401317
    Abstract: The present invention is directed to a method and system for rapidly identifying physical locations of manufacturing defects on the surface of a semiconductor die. The method and system first retrieve information about an electrical failure from an IC's electrical test result and then identify a set of electrical elements from the IC's layout design including a start resource and an end resource. Next, the method and system identify a physical signal path between the start resource and the end resource using the IC's layout design. Finally, the method and system examine a corresponding region on the semiconductor die that covers the physical signal path for manufacturing defects that may be responsible for the electrical failure.

  • Publication number: 20050057417
    Abstract: A dual band, dual pol, variable downtilt, 90 degree azimuth beamwidth antenna (10). The antenna includes dipole elements (12, 14) forming both a PCS band and a cellular band antenna. The PCS band antenna has two sections disposed each side of the cellular band antenna, the elements of each being positioned 90° with respect to the other. A microstrip feed network formed upon a common PC board (18) feeds the respective dipole elements, and has serpentine portions with a corresponding dielectric member slideable thereover to establish the phase of the associated dipole antennas and achieve a linear downtilt of the respective antenna array. A slide rod adjustment assembly (100) provides unitary movement of the dielectric members between two different slide rods. These dielectric members are secured with adhesive to the respective slide rods to achieve good dielectric control and no use of hardware.

  • Publication number: 20020091568
    Abstract: Global Positioning System (GPS), Personal Data Assistant (PDA), and wireless communications are combines in order to create a more personalized advertising experience. The invention creates and presents advertising content founded on individual user profiles integrated with the physical geographic location of a consumer. The invention solves the problem of advertising tailored so that it is appropriate to both the user and their current location by including a customer's profile and his/her current location into the advertising message. Also, the invention integrates location tracking, e.g. GPS technology, with a personal electronic calendaring system. Further, an advertising message is more personalized by using a relative address/directions that start from the current customer's location. This information could be provided in the form of driving directions, using the current physical position of the user as a start address.

  • Publication number: 20020087182
    Abstract: An applicator device (10) is provided for applying a patch (44) having an array of microprotrusions (90) to the stratum corneum. The applicator device (10) includes a device body (12) and a piston moveable within the device body (12). A cap (16) is provided on the device body (12) for activating the device (10) to impact the stratum corneum with a microprotrusion array (44,90). The device (10) is capable of being cocked by one handed operation of the user which allows the device (10) to be used by patients having neither the strength nor the manual dexterity to cock other types of applicator devices.
