Title: Steer-drive for vehicles
Inventor: ALEXANDER WARREN R
IPC: B63H25/10
Filed: 2001-12-06
Abstract: A steer-drive interposes respective left and right orbital gear drives (20, 22) into the vehicle drivetrain between the engine/transmission (10, 12) and the respective propulsion axles associated with each side of the vehicle. The orbital drive units comprise only an input gear (54) and an output gear (58) interconnected by at least one orbiting cluster gear (60, 61) that is supported in a rotating housing and also meshes only with the input and output gears. The orbital units are designed so that (a) when rotation of the housing (64) is prevented, driving torque is transferred at speed ratios selected to be as close to 1:1 as is practical, and (b) when steering torque causes rotation of the housing, the steering torque is added simultaneously in equal and opposite directions to the orbital units, causing the drive on one side of the vehicle to slow down at the same rate. The steer-drive is appropriate for the drivetrains of tracked vehicles, boats and airplanes.

Abstract: A tubular manifold adapted for engagement onto the suction wand of a conventional household vacuum cleaner. The upper bore of said manifold is adapted for hermetic fixation to the vacuum cleaner's suction wand and its lower bore is adapted for hermetic engagement onto the standard screw-capped aperture of a motor-oil shipping container, gasoline "ferry-can" or similar recycled liquid container. One end of a small-diameter flexible tube, thin enough for insertion down the oil dipstick tube of an engine is inserted through a close-fitting aperture pierced through the side of said manifold.  When the mated suction wand exerts negative pressure within the mated liquid container, used crankcase oil is drawn into the liquid container through the mated small-diameter tube. Threaded or conical adaptor rings may be provided to enable mating the manifold to different sizes of liquid containers and to different sizes of vacuum wands.  Vents through the manifold wall may also be provided to prevent the collapse of thin walled liquid containers. When changing the engine's oil filter, means are provided for capturing oil held in the old filter before it spills onto the ground.

Abstract: Cette invention est fondée sur la découverte selon laquelle des compositions et des préparations polymériques injectables et compatibles avec de l'acide nucléique peuvent être mises au point structurellement pour réguler in vivo l'activité de l'acide nucléique ou l'expression génique, par exemple, par régulation de la biodisponibilité de l'acide nucléique par modulation de la biodégradabilité et de la densité de réticulation du réseau formé par les constituants de la préparation. Le réseau polymérique encapsule l'acide nucléique, et non seulement régule la libération de l'ADN, mais le protège également de la dégradation. L'invention constitue une amélioration par rapport au modes de libération génique antérieurs, en ce que l'expression génique peut être régulée par modulation d'un réseau polymérique formé par combinaison d'au moins deux constituants solubles dans l'eau pouvant réagir l'un avec l'autre. L'acide nucléique d'intérêt est incorporé dans le réseau pour être libéré de manière constante, en fonction du niveau et de la durée d'activité ou d'expression voulus.

Filed: 2002-03-01
Abstract: Methods, systems, and computer programs for improved quality video compression. Image quality from MPEG-style video coding may be improved by preserving a higher number of bits during intermediate encoding and decoding processing steps. Problems of inverse discrete cosine transform (IDCT) mismatch can be eliminated by exactly matching the IDCT function numerical algorithm of the decoder to the IDCT function numerical algorithm used for the decoding portion of the encoder. Also included is an application of high precision compression to wide dynamic range images by extending the range of the "quantization parameter" or "QP". The extension of QP may be accomplished either by increasing the range of QP directly, or indirectly through a non-linear transformation. Also included is an application of extended intermediate processing precision and an extended QP range to reduced contrast regions of an image to extend the precision with which the low-contrast portions are compression coded.

Abstract: The error compensating system and method is used in electric power monitoring systems, e.g. protective relays, and includes a test unit (34) for applying a test signal to the front end of a data acquisition section of the power monitoring system and a phase reference module (30) which converts the test signal to a square wave having falling and rising edges corresponding to transitions between the positive and negative portions of the test signal. A  programmable logic device (20) determines the zero crossings of the sampled digital signal from the data acquisition system and then determines the time difference between a falling edge of the module output signal and the zero crossing (52) of the sampled digital signal. The time difference (54) is representative of the phase shift produced by the data acquisition components (16,18). A compensation circuit adjusts the digitally sampled signals with the amount of the determined phase shift.
