  • Publication number: 20160161601
    Abstract: Various implementations of the invention compensate for “phase wandering” in tunable laser sources. Phase wandering may negatively impact a performance of a lidar system that employ such laser sources, typically by reducing a coherence length/range of the lidar system, an effective bandwidth of the lidar system, a sensitivity of the lidar system, etc. Some implementations of the invention compensate for phase wandering near the laser source and before the output of the laser is directed toward a target. Some implementations of the invention compensate for phase wandering in the target signal (i.e., the output of the laser that is incident on and reflected back from the target). Some implementations of the invention compensate for phase wandering at the laser source and in the target signal.

  • Publication number: 20150293211
    Abstract: A laser radar, or “lidar” system, employs an asymmetric single-ended detector to detect received signals reflected back from targets. The asymmetric single-ended detector benefits from a reduced part count and fewer optical splices while nearly achieving a same gain as a symmetric differential detector.

  • Patent number: 8851328
    Abstract: Viscous compositions are metered discontinuously into storage vessels such as tubes, tubs, or cartridges, from a stable volume container free of dead space wherein the calculated volume, expressed as the mathematical product of adiabatic compressibility coefficients of the composition, the outlet pressure, and volume of the container exceed the metered volume.

  • Patent number: 7798374
    Abstract: In a process for producing crosslinkable organopolysiloxane compositions, in particular organopolysiloxane compositions which can be crosslinked at room temperature, the organopolysiloxane compositions are stored in a storage unit before being packed in moisture-proof containers, the storage having a storage capacity of at least 15 minutes of production capacity of the mixture, the essentially dead-space-free storage unit continually having an internal pressure of more than 1200 hPa during filling.

  • Patent number: 7555567
    Abstract: A keyboard/video/mouse (KVM) switching protocol is disclosed in which KVM information is applied to a network of workstations. At least one data converter communicates on the workstation network and retrieves KVM information from the workstation network that is addressed to a server assigned to the converter. The converter places the KVM information in a format suitable to the assigned server and applies the converted KVM information to the appropriate standard device ports of the server. The system provides motherboard access to the servers that is characteristics of KVM switches but provides essentially unlimited scalability not known in traditional KVM switches.

  • Patent number: 5724238
    Abstract: A power supply circuit generates an alternating driving voltage for switching a pane or panel between a transparent state and a substantially opaque state. The pane or panel is, for example, a window with a variable transparency in an aircraft cabin divider. The circuit converts a D.C. voltage that is available, for example, from the aircraft's on-board power supply, into a positive and negative D.C. voltage. These voltages pass through a push-pull output amplifier that is under the control of a clock signal generator to produce the alternating driving voltage at the output of the push-pull amplifier connected to transparent electrodes of the pane or panel that contains liquid crystals. Status sensors may influence the operation of the clock signal generator and/or of the push-pull amplifier.

  • Patent number: 5195428
    Abstract: A press for the production of pressed board with injection of steam utilizes press platens to which the steam is fed to the steam-feed channels from opposite sides in a collision flow, the channels communicating with steam-nozzle bores opening at the pressing surface and such that the cross section of each channel is equal to at least 60% of the total flow cross sections of the boards communicating with that channel. Before the pressing commences, the channels are through-flushed with steam to flush air from the channels and bores and to evacuate air from the pressed mat by a venturi effect.
