  • Patent number: 8065489
    Abstract: Method and apparatus for managing concurrent access among computers to a bitmap stored on disk storage. In some examples, a command is received from a requesting computer of the computers, the command indicating that one or more bits in the bitmap are to be cleared. The bitmap as stored on the disk storage is updated responsive to the command to clear the one or more bits in the bitmap. Synchronization data associated with the bitmap is stored. The synchronization data is configured to distinguish between a current generation and a previous generation of the bitmap, and to specify an action to be performed in response to receiving a subsequent command for accessing the bitmap if the subsequent command identifies a previous generation.

  • Publication number: 20100326903
    Abstract: A device (20) for improving drainline clearance for use with an ultra low flushing volume toilet (24). The device (20) includes a centrifuge separator means (30), for separating liquids (L) and solids (S), and a reservoir (42). The separator means (30) has a substantially horizontal inlet (32), adapted for connection to the outlet (26) of a toilet pan (24), an outlet (36) primarily for solids (S) and an outlet (38) primarily for liquids (L). The reservoir (42) is beneath the separator means (30) and has an inlet (38) in fluid communication with the liquids outlet (38) of the separator means (30). The reservoir (42) is adapted to syphonically empty substantially all of its contents into a sewerage drainline (22) after at least 2 flushes of the toilet (24). Further, the separator means (30) and the reservoir (42) have a combined vertical dimension less than the maximum height of the toilet pan outlet for installation adjacent the toilet (24) and substantially above the floor level (F) of the toilet (24).

  • Patent number: 7752480
    Abstract: A system and method for switching digital circuit clock net driver without losing clock pulses is presented. A device uses glitchless clock selection logic, which includes an edge detector, to select a clock signal to provide to device circuitry based upon the device circuitry's performance requirements. When the rising edges of a first clock signal and a second clock signal align, the edge detector momentarily pulses a clock switch signal, which is used to clock in a clock selection signal to a multiplexer. As a result, when the clock selection signal is high, the device waits until the clock edges are aligned before switching clock signals.

  • Patent number: 7719227
    Abstract: Electrical energy supply methods and electrical energy power supplies are described. According to one aspect, an electrical energy supply method includes providing first and second battery assemblies individually configured to store electrical energy, coupling the first and second battery assemblies to form a unitary device configured to supply electrical energy to a load, charging one of the first and the second battery assemblies using electrical energy from a supply at a first moment in time, discharging electrical energy from the first and second battery assemblies to the load at a second moment in time, and disabling discharging of electrical energy from the other of the first and second battery assemblies during the charging.
