Abstract:
A display apparatus displays projected images to a user. A viewing station comprising a dummy cockpit structure receives the user such that the eye of the user at a point in time is at an eyepoint in a viewing volume of possible eyepoints defined by the range of movement of the user at the viewing station. First and second projection screen portions face the eyepoint. A first projector directs light to shine through an aperture in the first projection screen portion so as to project an image on the second projection screen portion. A mask is adjustably supported between the aperture and the viewing station, and is configured so that it covers the part of a last lens surface of the projector viewable through the aperture when viewed from any eyepoint in a viewing volume of possible eyepoints of the user, and prevents the user seeing light scattered from the last optical surface of the projector. The second projector projects light on the first screen portion and an inside surface of the mask so as to form thereon a second image visible to the user.
Abstract:
A security system in a vehicle extends its protection to installed equipment of the vehicle, such as audio components, navigation systems, and entertainment systems. The installed equipment is armed and disarmed by the security system, preventing the equipment from normal functioning after unauthorized removal. The security system further enables programming, monitoring, and diagnosing of the installed equipment through the security system's remote control, through a configuration and maintenance tool that connects to the security system, or through other items of installed equipment within the vehicle, such as a rear-seat entertainment system.
Abstract:
An administration model is provided that uses access control lists to define permissions for users and groups of users. The model identifies a number of objects to be administered. Associated with each of these objects is a set of administrative operations that can be performed on the object. For each of these operations a permission in an access control list entry is defined. The protected resources are arranged in a hierarchical fashion and an access control list can be associated with any point in the hierarchy. The access control list provides fine-grained control over the protected resources. At the time an administrator requests to perform an operation, the administrator's identification is used to look up the prevailing access control list to determine whether the operation is permitted.
Abstract:
A circuit for processing the outputs of an array of photoconductive detectors, includes amplifiers (101) for amplifying the detector outputs and analogue-to-digital converters (109) for digitizing the amplified outputs. The A to D converters oversample the detector signals. A digital processor (110) then applies a linearity correction to the digitized signals. The circuit is particularly suitable for processing the signals from an array of photoconductive detectors in an FT-IR microscope.
Abstract:
The present invention provides a simulation for displaying a screen formulated from data, such as a FLIR sensor, relying on color definitions that are more readily supported by common image generators, most preferably 8-bit per channel RGB color processing and video output. The system has an image generator that transmits a video signal of at least two digital data channels, and a display system with a combiner circuit and a visual display device. The bit sets of the channels each represent a respective value of the data variable at a resolution for that channel, and the bit sets of the second channel each represent a respective value of the data variable at a second resolution higher than the resolution of the first channel. Combiner circuitry receives the channels of video output and processes these channels to select the channel which represents the accurate data unaffected by clamping. It is preferred to provide at least three channels of pixel data representing the value of the display data, in three different resolutions and ranges, high resolution; middle resolution and low resolution. In the preferred embodiment, the data displayed on the display device are simulated FLIR infra-red intensities, which correlate to the temperatures of the simulated objects being viewed. Preferably, the ranges of different resolution IR data encompass the ambient temperature being simulated, because attenuation of infra-red in reality tends to compress all detected infra-red temperatures to a narrow field around ambient temperature.
Abstract:
A manufacturing machine assembly and associated method for producing a coupon card. The machine assembly includes a support frame with a printing station for printing indicia on a top surface of a continuous sheet of stock in two parallel rows that define a first strip and a second strip of the stock. A forming station removes a release liner from the first strip to expose an adhesive layer. The forming station also moves the adhesive layer of the first strip into a bonded relationship with the release liner of the second strip to mate the first and second strips and form a continuous series of two-sided coupon cards. Exit rollers completely cut through the series of two-sided coupon cards for forming and separating individual coupon cards from the continuous sheet of stock. A first take-up roller collects a first continuous web of scrap stock. A scoring roller only cuts through a portion of the second strip of stock and a stripping roller removes the cut portion of the second strip of stock, which is now a second continuous web of scrap stock. A second take-up roller collects the second continuous web of scrap stock.
Abstract:
A plasma mass spectrometer comprises a plasma torch (1) for generating ions from a sample introduced into a plasma (2), a nozzle-skimmer interface (3,5) for transmitting said ions into a first evacuated chamber (11), ion guiding means (12), an apertured diaphragm (18) dividing said first evacuated chamber (11) from a second evacuated chamber, and an ion mass-to-charge ratio analyzer in the second chamber for producing a mass spectrum. The ion guiding means comprises a multipole rod-set (13,14,15), means for applying an AC voltage between rods in the set, and means (22) for introducing into said ion guiding means an inert gas selected from the group comprising helium, neon, argon, krypton, xenon and nitrogen so that the partial pressure of said inert gas inside said rod-set is at least 10−3 torr. Interfering peaks in the spectrum, such as Ar, are thereby reduced.
Abstract:
A current transducer includes a current transformer in which the conductor carrying the current to be monitored constitutes the primary. The transformer secondary is wound on a toroidal core. The transformer is operated below its cut-off frequency such that the output from the secondary is proportional to the differential of the current in the primary. The secondary output is integrated by an integrator to provide a measure of current in the primary and the integrator is initialized at predetermined intervals. A current measuring device for an electric machine, for example a reluctance machine, includes at least one of the current transducers.
Abstract:
Coating dispenser apparatus and methods which utilize a snuff back device for removing a small amount of coating material from the discharge passage of the dispenser upon shut-off thereof at the end of a coating run. A control is provided which discharges the material removed from the discharge passage back into the discharge passage upon a predetermined delay after the start of the next coating run. The disclosed methods contemplate the discharge of coating material back into the discharge passage in the middle of the next coating pattern, or depending on the application, during any segment of the next coating pattern after a defined leading edge of the pattern is created, during which segment the coating material discharged back into the discharge pattern smoothly blends into the coating pattern as it is applied to a substrate. The apparatus and methods are especially useful for applying conformal coating patterns onto circuit boards.
