    摘要： A system for high density holographic storage announced by Cal Tech is improved. The basic Cal Tech system records successive holograms by physically shifting the recording medium relative to the paired reference and signal beams. By depending on Bragg selectivity, successive holograms may be overlapped and still differentiated in the direction of overlap--in the "x-direction". The claimed system improves storage density by tilting the holographic plane to introduce a Bragg component in the y-direction, thereby enabling differentiation of overlapping holograms in that direction as well.

    摘要： A device for detecting intrusion for security or inventory control purposes includes a mat having loosely superposed metallic foil sheets separated by a sheet of paper or plastic foil dielectric to form a capacitor, and circuitry connected to provide a voltage differential to the capacitor and to detect a change in capacitance caused by weight applied to or removed from the mat. The circuit includes a voltage regulator to regulate the applied voltage differential, a unity gain amplifier to isolate the mat capacitor from change signal amplifier circuitry, a comparator to compare the amplified change signal with user settable thresholds, and a one-shot multivibrator for initiating an alarm signal pulse when one of the thresholds is exceeded. The sheets are preferably aluminum foil backed with plastic film and, in one form, are wrapped one around the other.

    摘要： A tester for a relay comprises an enclosure, a testing circuit that includes a controller, electronic switch components, a power source, indicator LEDs, a test start switch, a relay selector switch, and five electric leads each connected with one terminal of the relay. With the relay selector switch toggled to indicate the type of relay being tested, with power supplied to each lead, and with the test start switch actuated, the controller sets each lead to ground, in turn, and then count the number of other leads that are grounded as a result. The controller then illuminates the at least one indicator to indicate either the passing relay test or the failed relay test based on the counts measured. Once the leads connected to the relay coil are identified, cyclic testing of the relay can be performed.

    摘要： Disclosed herein are techniques for the reduction speckle of a projection display system using novel lenslet integrators and related methods. In one embodiment, a lenslet integrator system for reducing speckle on a display screen may comprise a first lenslet array configured to receive incoming light for use in displaying an image on a display screen. Specifically, the first lenslet array has motion sufficient to reduce speckle by averaging multiple speckle patterns across its array. Such an exemplary system may also include a second lenslet array configured to receive light that is roughly focused from the moving first lenslet array, due to the motion of the first array. In addition, such systems may also include an output lens configured to receive light focused from the second lenslet array for output from the system for illumination of the display screen.

    摘要： To provide an optical recording apparatus capable of effectively suppressing useless fixation to an information-unrecorded area during a fixing process with a simple structure, and an optical head. Upon recording information, a movable lens of an expander lens 104 is positioned in an information recording position. In an information fixing process, the movable lens of the expander lens 104 is positioned in a fixing-process position. In this case, a range of irradiation to the recording medium with the data light becomes somewhat wider than that in the information recording process. Accordingly, it is possible to fix the information to an area irradiated with the data light in the information recording process without fail. In addition, the irradiation range is only somewhat wider than that in the information fixing process, making it possible to minimize the region uselessly subjected to the fixing process.

    摘要： A hologram apparatus comprises a vibration detection beam generation unit to apply a vibration detection beam, incoherent to the data and reference beams and to detect the presence/absence of vibrations, to the hologram recording medium; a light reception/determination unit to receive the vibration detection beam emitted from the medium after the beam is applied to and propagates through the medium and to determine whether the beam receiving position is within a preset range; and an interruption unit to interrupt at least one of the data and reference beams from being applied to the medium, when this unit has determined that the position of beam reception is not within the preset range.

    摘要： The present invention provides a method and system for the reference, archival and retrieval of symbolically linked information despite idiosyncratic symbol usage. A master symbol database stores a plurality of master symbols, wherein each master symbol is formatted according to a predetermined structure. Each master symbol in the master symbol database is linked to a parent identifier that identifies a unique object. Users may archive or retrieve symbolically linked information in an information database by providing an input symbol. The input symbol is normalized and the master symbol database is searched to find a matching master symbol. The parent identifier linked to the matching master symbol is then used to retrieve or archive information in the information database.
