Abstract: An infrared imaging microscope, particularly of the type used to carry out FT-IR measurement, has a detector in the form of a small detector array of individual detector elements. The outputs of the detector elements are fed in parallel to processing means which process the output signals. The use of a small array means that the outputs can be processed without the need for complex multiplexing or perhaps no multiplexing at all thus avoiding the reduction in signal to noise ratio which is associated with large scale multiplexing. The small detector array will generally have between 3 and 100 detector elements. Typically the upper limit will be 64 and a preferred arrangement has 16 detector elements.

Abstract: Access Control Lists (ACLs) are used to describe the permitted actions (permissions) on protected network computer system resources or objects associated with an client or user identity. An identity may be an individual user or group of users. The actions are used to represent the different access methods available on a particular projected object or resource. A new action grouping mechanism is provided which tags each action with an action group name. The grouping of actions facilitates a larger permission set to be defined in an ACL, whereas action permission indicators can be reused for unique action definitions within various action groups. This effectively extends the finite total number of permissions available within a security system, allows a more descriptive and extensible permission mechanism in an Access Control List, as well as aiding in the simplification of management and definition of security policies.

Abstract: A receiver for high-speed serial communication that uses an interface such as XAUI is disclosed with automatic lane assignment. The receiver analyzes incoming data packets and determines the lanes based on the data packets. The lanes are then automatically reordered. The receiver allows the lanes to be connected to the receiver arbitrarily, thereby providing additional layout freedom to circuit board and ASIC designers.

Abstract: An entertainment console installed in a vehicle includes a docking bay for docking portable entertainment devices, such as portable media players (PMPs). A base of the console may be attached to the passenger compartment ceiling, with a display that can be flipped down from the base. A docked PMP can be played through the console. Video may be rendered on the console screen, while audio may be played through the console speaker(s), headphone jacks available on the console, or the speakers of the vehicle's audio system. Power for the PMP's operation is provided by the vehicle's electrical system. The console may also include additional docking bay(s), enabling simultaneous docking of multiple PMPs that may be played at the same time. A presentation from one PMP (e.g., a DVD player) can also be recorded on another PMP (e.g., a hard drive-based player). The screen may rotate around the vertical axis.

Abstract: A turbocharged internal combustion engine comprising: a turbocharger (15) actuators for opening and closing the exhaust valves (a, b) and an electronic controller which controls operation of the actuators to thereby control opening and closing of the exhaust valves (a, b). The exhaust valves comprise a first exhaust valve (a) connected to a first exhaust duct (14) and a second exhaust valve (16) connected to a second exhaust duct (16). The first exhaust duct (14) is connected to the turbocharger (15) so that exhaust gases passing through the first exhaust duct (14) drive the turbocharger (15). The second exhaust duct (16) bypasses the turbocharger (15) and the combusted gases flowing through the second exhaust duci are exhausted without passing through the turbocharger (15).

Abstract: An antenna disposed within a shielded enclosure, the antenna being disposed adjacent an electromagnetically transmissive closure member which covers a non-shielded aperture in the shielded enclosure. The electromagnetically transmissive closure member may, depending upon its dielectric properties, provide electromagnetic amplification for the antenna disposed thereunder to increase the effective signal propagation or reception.

Abstract: A switched reluctance drive is supplied from a power source. The phases of the machine are controlled by a current controller which uses an excitation strategy to minimize the supply current drawn for a particular output. The strategy alternates the excitation between two phases for a given time until the rotor moves to a desired position. A method of starting a switched reluctance motor having a stator with at least two phases, a moveable part, and a position transducer includes determining from transducer output a plurality of phases that are available to produce force in a desired direction, energizing a first phase of the available phases for a predetermined time period that is independent of the transducer output, and energizing a second phase of the available phases after energization of the first phase is initiated.

Abstract: With reference to FIG. 1, the present invention provides an internal combustion engine which operates repeatedly a multi-stage combustion process, the engine having a combustion chamber, supply means (12) for supplying fuel and air to the combustion chamber and exhaust means (16) for exhausting combusted gases from the combustion chamber. During a first stage of combustion (FIG. 1(a)- FIG. 1(c)) the supply means (12) supplies fuel and air to the combustion chamber and the supplied fuel and air are combusted by a spark ignition Otto process or by a compression ignition Diesel process. Then (FIG. 1(d)) at least a majority of the combusted gases resulting from the first stage combustion are retained in the-combustion chamber, additional air is supplied to the combustion chamber(FIG. 1(e)) and the resulting mixture is combusted in a second combustion stage (FIG. 1(e) and FIG. 1(f))by homogeneous charge compression ignition.

Abstract: DC power savings in a mobile communication device can be achieved by dynamically adjusting the biasing for a receiver based on the communication link quality. The output signal levels of at least one low noise amplifier (LNA) are monitored to identify the DC operating conditions for the LNA. Closed loop control of the DC biasing is adjusted based on a comparison between the monitored DC operating conditions and a reference signal. The output of the LNA is also coupled to a radio receiver section that is configured (e.g., SW or HW) to evaluate the link quality based on various criteria such as inter-modulation distortion, noise, interference, fading, etc. The reference signal that is used to control the DC biasing of the LNA is adjusted (periodically, continuously, or on demand) in response to the evaluated link quality. The dynamic biasing yields acceptable signal reception with low DC power consumption.

Abstract: A system displays video to a user and has a display device with a field of pixels. It displays video to the user in the form of a series of discrete sequential frame images each made up of a first predetermined number of bit planes in which the pixels of the display are either off or have a color and intensity that is uniform over the field of pixels. The apparatus detects when a movement condition is present, such as rapid head movement or an object in the video crossing the display rapidly, in which condition the user's eye may tend to track across the display device at a rate at which perception of the video displayed may be reduced in quality, and it generates a condition-present signal when such a movement condition is detected. Responsive to generation of said condition-present signal, the apparatus causes the display device to display the frame images using fewer bit planes for each frame image than when said movement condition is not detected.

Abstract: The present invention relates (with reference to FIG. 1) to an internal combustion engine in which a combustion chamber (12) can be connected to a reservoir (16) for storing compressed air. Gas flow control valve means (15) controls flow between the chamber (12) and reservoir (16) so that air pressurised in the chamber (12) can be relayed to charge the reservoir (16) and pressurised air can be delivered to the chamber (12) to drive piston (10). The chamber (12) is also used for combustion of fuel. The invention also relates to a valve mechanism for controlling the flow of pressurised air between the chamber (12) and reservoir (16), in which a balancing force is applied to the gas flow control valve (115) to cancel the force on the valve (115) arising from the pressure applied to the back face of the valve (115).

Abstract: A display apparatus for displaying projected images to a user comprises an enclosure with an aperture between the interior and exterior of the enclosure. A projector adjacent the aperture projects light through the aperture and against a screen surface to form an image that is visible to the user at a viewing station. A mask blocks the light from the projector proceeding to the eyepoint of the user. The method of the invention comprises projecting an image through the aperture onto the projection screen and blocking a portion of the light that is scattered from the last lens surface with the mask while permitting the image to proceed to the projection screen to be viewed.

Abstract: A system and method for managing imaged documents includes a manager computer with a scanner and a database connected thereto. The manager computer includes a program for managing the imaged documents. Information within one or more predetermined zones within an imaged document is read and compared against a database of reference information so as to record each document as a “Main Document” or an “Attachment.” For freight documents, “Main Documents” are classified as an “Accounting Copy” or a “Delivery Receipt,” and Bill-of-Lading numbers are read and checked for validity; invalid numbers are flagged for manual recording. Optical character recognition or manual entry is used for textual information, or bar code recognition is used to read bar code information in the zones. Batches of documents are prepared in related document groupings for automated grouping of the electronic image records under related tracking numbers.
