  • Patent number: 8317781
    Abstract: Switching power supplies made in accordance with the disclosed technology drive flash lamps of dermatologic treatment devices to emit a sequence of relatively small light pulses that are aligned with particular locations within the waveform of the AC line source. Such power supplies not only enable sufficient light energy in aggregate to therapeutically heat target chromophores in a skin region without causing undesired damage to surrounding tissue, but also provide the added benefit that the corresponding electrical energy need not be substantially drawn from any charged capacitor. The disclosed power supply further compensates for performance degradation of the flash lamps during their usable life, by modifying its operation based on predetermined values that are indicative of flash lamp aging/efficiency characteristics. The flash lamps and their associated stored values are preferably incorporated into a replaceable cartridge that facilitates user maintenance of the dermatologic treatment device.

  • Patent number: 8264970
    Abstract: An OAM link trace message is sent from a source node to a target node in a link state protocol controlled Ethernet network. The link trace message using an 802.1ag format except, as a destination address, it uses either the unicast Ethernet MAC node ID of the target node, or the multicast destination address of the service instance. A method of network topology verification in a link state protocol controlled Ethernet network checks the link state protocol database at a node to ascertain the control plane topology view of at least part of the network. It then executes one or more Ethernet OAM commands from the node to ascertain the data plane topology view of the same part of the network. The control plane topology view of the network is compared to the data plane topology view of the network to see if they match. An error is flagged if they do not match.

  • Patent number: 8225527
    Abstract: Described are an apparatus and a method for cooling a web. The apparatus includes an inner cylinder having a void therein and configured for coupling to a gas source. The apparatus also includes an outer cylinder having an inner surface, an outer surface to support a web and apertures between the inner and outer surfaces. The outer cylinder rotates about the inner cylinder so that gas provided to the void of the inner cylinder flows through the apertures that are adjacent to the void and passes to the outer surface of the outer cylinder to increase the heat transfer between the web and the outer cylinder. The volume of gas introduced into the vacuum deposition chamber during a process run is thereby limited. Advantageously, the apparatus enables higher deposition rates and increased productivity.

  • Patent number: 8219626
    Abstract: A system and method integrate synchronous electronic (e.g., chat) communications with asynchronous electronic communications in the form of body-less electronic mail messages (emails). Body-less emails have a subject line but lack a message body capable of receiving message content. When converting a synchronous electronic communication into a body-less email, a processor places each text message of the synchronous electronic communication into the subject line of the body-less email. When converting a received body-less email into a synchronous electronic communication, the processor places each text message in the subject line of the body-less email into a chat format. A user can readily transition between asynchronous and synchronous communications.

  • Patent number: 8205064
    Abstract: In certain systems, local requests require corresponding associated information to be present in order to be serviced. A local memory stores some of the associated information. There is latency associated with retrieval of associated information that is not immediately available. Logic operates for each local request to access the local memory to ascertain whether the associated information corresponding to the local request is present. If the associated information is present, a request is placed in an output request queue to service the local request. If the associated information is not present, a request is placed on a bypass path to retrieve the associated information. Requests issue from the bypass path with priority over requests from the output request queue. Useful work is thereby done during the latency of associated information retrieval. The arrangement is useful in a TLB in an MMU.

  • Patent number: 8204148
    Abstract: Described is a space-time digital power amplifier that can be used to generate an arbitrary waveform for a carrier signal. The space-time digital power amplifier employs temporal modulation of transmit signals generated by an array of transmitter modules. The RF signals transmitted from the array are spatially combined through free space propagation to generate the desired waveform. Advantageously, no digital-to-analog conversion is required and upconversion is unnecessary. The digital power amplifiers for the transmitter modules can be combined in a single chip package. The space-time digital power amplifier enables high power efficiency to be realized using pulse-shaped waveforms thus eliminating any need for the power amplifiers to operate over a wider bandwidth with a spectrally unconfined waveform.

  • Patent number: 8197076
    Abstract: Described is a magnetic membrane mirror having a flexible membrane comprising a magnetic material and having a high reflectance. The flexible membrane is secured over a frame to enclose a volume between the frame and membrane. A transmembrane pressure is established to achieve a desired mirror shape or curvature. Curvature can be changed by modifying the transmembrane pressure by increasing or decreasing the pressure in the enclosed volume. An array of electromagnetic actuators generates individually-controlled magnetic fields to cause localized displacements of the mirror surface. The magnetic membrane mirror can be constructed with inexpensive components and can be used as a dynamic component in an adaptive optical system.
