  • Patent number: 7086855
    Abstract: The invention is an apparatus that is a synergistic combination of a windshield and a pilot light assembly for a gas burner heater. The apparatus provides reliable operation of the gas burner heater in high air flow conditions, where the air flow would normally cause the pilot light to be extinguished. The windshield, which is a partially perforated tubular chamber, provides a protected zone against high velocity air infusion for the entire pilot light assembly. The apparatus works in concert with the pilot light assembly, which also has components that provide protection from wind and can be quickly removed allowing quick cleaning and easy maintenance. The major components of the pilot light assembly are a pilot light orifice with a flame, a vented pilot housing (stack), a flame deflector cap, a pilot light gas line, a thermocouple with connecting electrical leads, a pilot base, a mounting bracket, and a windshield that surrounds the pilot light and the thermocouple.

  • Patent number: 7039072
    Abstract: Multiple streams of bits are received. One or more bits are selected from a stream of bits based, at least in part, on a space control register value and a time control register value. In one embodiment, a time control register stores a value indicating a selected bit from a sequence of bits, a counter counts bits in the sequence of bits from a predetermined bit, and a comparator is coupled to the time control register and to the counter to generate a load signal when a value stored in the time control register and a value provided by the counter are equal. The load signal causes the latch to load a value output by the multiplexer.

  • Patent number: 7039046
    Abstract: The present invention reduces the cost of a minimally configured network device by providing a network device with a distributed switch fabric. Such a network device locates a portion of the switch fabric functionality on each forwarding card allowing the minimal network device configuration to include less than the entire switch fabric functionality. The cost of the minimal configuration is, therefore, reduced allowing network service providers to more quickly recover the initial cost of the network device. As new services are requested, additional functionality, including both forwarding cards and universal port cards may be added to the network device to handle the new requests, and the fees for the new services may be applied to the cost of the additional functionality. Consequently, the cost of the network device more closely tracks the service fees received by network providers.

  • Patent number: 7039361
    Abstract: A method and system for reducing electromagnetic interference emanating from and existing within a network device is provided. A layer of foam having a high insertion loss in the range of electromagnetic interference generated by the network device is provided on at least a portion of an inner surface of the telecommunication device. Electromagnetic interference generated by the components of the device is at least partially absorbed by the foam. The foam may be applied to the inner surface of the chassis of the device, or it may be applied on or near a high speed integrated circuit chip, or both.

  • Patent number: 7039045
    Abstract: A switch element is configured to extend communications between data lines. The switch element has an ingress stage, a center stage, and an egress stage. The switch element connects to two sets of data lines. Time slots are identified on each set of data lines. Time slots from one set of data lines are assigned to ingress and egress edges on a center stage device. The time slots from each set of data lines are also mapped to one another, so that each time slot in one set of data lines is mapped to only one corresponding time slot in the other set of data lines.
