Abstract: A Raman spectroscopy apparatus comprises an imaging optical system that transmits light from an object to a spectrograph along an optical path. A scanning device intersects, and is movable with respect to, the optical path. Light is directed onto the scanning device to illuminate the object at a plurality of illumination points. The imaging optical system transmits Raman scattered light emitted from the object at the illumination points to an intermediate image plane, the scanning device being located at the intermediate image plane, and transmits the Raman scattered light from the intermediate image plane to the spectrograph. In comparison with conventional confocal Raman spectroscopy, the apparatus can perform Raman analysis of a sample more quickly, and in comparison with conventional line scan Raman spectroscopy the apparatus can perform Raman analysis more accurately.

Abstract: A display system 10 for displaying information at a point of product display in a retail outlet comprising a communicator 12 for transmitting display information to a remote display module 18, the display module 18 being adapted in a first, low power mode to display information and in a second, higher power mode periodically, in a predetermined manner, to communicate with the communicator 12, the system 10 preferably being configured to enable determination of the accuracy and automated correction of the synchronization of a periodic communication between the communicator 12 and the display module 18 while the display module 18 continues to switch between first and second modes of operation enabling a low overall consumption of power by the display module 18 and more preferably wherein the display module 18 is adapted to switch between first and second power modes between receipt of a synchronization signal and a display information signal from the communicator 12.

Abstract: A latch handle assembly includes a bezel disposed within a panel and a handle having a center portion, a first grip portion, and a second grip portion. The center portion is disposed between the first grip portion and the second grip portion. The center portion pivotally mounts the handle within the bezel.

Abstract: A seat identification system for passengers in a cabin of a commercial airliner. Four sign components, identified as the aisle, mile, row and seat components, are arranged and positioned throughout the airplane in a configuration that allows the passengers to receive information about their seats when needed. The aisle signage markers direct the passengers down the appropriate aisle which leads to their seat. The interval row markers or mile markers provide a general location of the particular row in the aircraft for the passenger's seats. The individual row markers are preferably located in the passenger service unit modules and in viewing channels in order to allow the markers to be visible from the aisle. The seat markers are located preferably on the headrest on each seat and are the final vindication that the passenger is in the correct seat.

Abstract: A scram signal generating circuit for nuclear reactor installations monitors a flow signal representing the flow rate of the liquid sodium coolant which is circulated through the reactor, and initiates reactor shutdown for a rapid variation in the flow signal, indicative of fuel motion. The scram signal generating circuit includes a long-term drift compensation circuit which processes the flow signal and generates an output signal representing the flow rate of the coolant. The output signal remains substantially unchanged for small variations in the flow signal, attributable to long term drift in the flow rate, but a rapid change in the flow signal, indicative of a fast flow variation, causes a corresponding change in the output signal. A comparator circuit compares the output signal with a reference signal, representing a given percentage of the steady state flow rate of the coolant, and generates a scram signal to initiate reactor shutdown when the output signal equals the reference signal.
