  • Publication number: 20050073955
    Abstract: Described are a system and method of adaptively managing bandwidth between services contending for the bandwidth on an optical link. Bandwidth is allocated to each service contending for bandwidth of the optical link. For each service, a current utilization metric representing a measure of current usage of the allocated bandwidth by that service is computed. Additional bandwidth is allocated to one of the services in response to the current utilization metric of that service if bandwidth usage of the optical link is currently at less than full capacity, otherwise the bandwidth allocation between the services is balanced in response to the current utilization metric of at least one of the services if the bandwidth usage of the optical link is currently at full capacity.

  • Patent number: 6837594
    Abstract: A low-power illumination apparatus may be used in areas where conventional incandescent illumination would be unsafe, especially to children or small pets. The apparatus may be configured to appear as a window candle and can be safely installed in windows which are easily accessible to children. Safe application is accomplished by supplying a low-wattage bulb with a low voltage, providing a resettably-fused bulb supply within the apparatus to prohibit the use of high-wattage bulbs and an interlocking base attached to the window frame which prevents the apparatus from being inadvertently removed or tipped over.

  • Patent number: 6749133
    Abstract: A substance delivery apparatus, such as a spraying apparatus, that includes an adjustment element for regulating the flow of at least one substance between at least one inlet and at least one outlet. The adjustment element is displaceable between a first position, corresponding to a first delivery condition of the at least one substance, and a second position, corresponding to a second delivery condition of the at least one substance, and the adjustment element comprises at least one sealing element for facilitating airtight fluid communication in association with at least one of the first and second delivery conditions.

  • Patent number: 6425534
    Abstract: A sprayer head is provided for attachment to a container containing a chemical product to be diluted by a carrier stream. The sprayer head includes a hose attachment member having structure for attaching the sprayer head to a source of the carrier stream. The sprayer head also includes a cap member, including structure for attaching the sprayer head to the container and a control mechanism movably connected to the cap member for controlling fluid communication between the cap member and the container. The control mechanism can be either reciprocated or rotated so that the sprayer head can be used either to spray a low viscosity liquid product in varying dilutions or to dilute and spray a mixture of high viscosity liquid, gelatinous or powdered product and carrier stream fluid. The control mechanism includes a seal member having product apertures of increasing sizes for controlling the varying dilutions.

  • Patent number: 5829869
    Abstract: An electric candle light system is provided wherein one or more lamp holders (20) are releasably coupled to a building structure (12) by respective number of bracket members (70). Each bracket member (70) includes a wireway (80) through which a power cord (100) is passed. Each lamp holder (20) includes an open channel (44) into which the respective bracket member (70) is received. A pair of insulation piercing terminals (50) disposed within the open channel (44) make an electrical connection between the lamp leads (26, 28) and the respective insulated conductors (104, 106) of the power cord (100).

  • Patent number: 5165171
    Abstract: A unitary metal pizza slice server has a triangular food support surface with a first handle portion projecting from its base and an overlying second handle portion resiliently joined at the distal end of the first portion to form a U-shape handle. The second handle portion terminates in a concave U-shaped food gripper facing the base of the triangular food support surface. The handle has a zone proximate the food support surface of a sufficient width and length in order to dissipate heat from a piping hot pizza slice on the food support surface so that the portion of the handle beyond this zone may be gripped by an unsheathed hand of a user. The handle is also sufficiently long to ensure sanitary serving of the pizza slice.
