Abstract: Methods and apparatus for taking autofluorescence images with a fundus camera capable of a field of view of at least 30 degrees and preferably 50 degrees or more using high quality thin film optical interference filters. In one embodiment, a filter set is disclosed for achieving this functionality. Using these methods and/or apparatus, a practitioner can (among other procedures, which are described) take high-quality autofluorescence images of the fundus using a CCD camera that does not have to be cooled, take such images without exciting damaging photochemical reactions in the retina, detect accumulation of fluorophores in the retina prior to the significant accumulation of fluorophores in the retinal pigment epithelium, and topographically localize and quantitate retinal abnormalities and retinal pigment epithelium abnormalities.

Abstract: A method and apparatus for using satellite positioning systems to more precisely locate the position of a portion of an attachment on an earthmoving machine is disclosed. More specifically, satellite positioning system antennas are mounted to an arm or other point relative to the arm of an illustrative excavator. A reference point relative to these antennas is used to determine the precise location of a portion of an attachment to the excavator, such as the prongs of a bucket. In one embodiment, an angle sensor or inclinometer is used to ascertain the position of the prongs when the bucket is scooped. In another embodiment, an angle sensor or inclinometer is used to measure the tilt of the body of the excavator, such as would occur when the excavator is resting on a sloped surface.

Abstract: In an elevator system that has an elevator hoistway, a plurality of hoistway doors arranged above each other each with at least one horizontally moveable hoistway door panel, and an elevator car with a car door that has at least one horizontally movable car door panel, fastened to the car door panel is a vertically extending barrier rail. In each of the areas lying in the vertical direction between the hoistway door panels of adjacent hoistway doors two locationally fixed stopping dogs that are vertically spaced from each other are arranged so that in each case one of the stopping dogs limits the opening movement of the barrier rail, and thereby of the car door panel, when the position of the elevator car deviates in the upward direction or in the downward direction by a certain minimum distance from the intended stopping position.

Abstract: The invention relates to a device for processing an edible product in the form a viscous to pasty mass (1), especially an edible product based on a fat mass, such as chocolate, or based on water, such as ice cream. Said device comprises a dosing unit (2) for the dosed delivery of a specific volume of the mass (1) to shaping units (13). The movement of the displacement element (6) determining the dosage volume is performed via servo drive (9) while an inlet (4) and an outlet (5) are closed and opened via servo drive or pneumatic drive, respectively. Preferably, the displacement element is embodied as a combined lifting/rotating plunger (6) which can perform a linear movement for a suctioning lift and a dosing lift while being able to perform a rotary movement for opening and closing the inlet (4) and the outlet (5), i.e. a valve function.

Abstract: Disclosed is a method and apparatus for processing signals in a satellite/laser positioning system capable of generating location coordinates from received satellite signals and a received laser signal. A height coordinate bias value is maintained by a filter processor during periods when the laser signal is available. The height coordinate bias value represents an estimated difference between a satellite signal derived height coordinate and a laser signal derived height coordinate. During periods when the laser signal is available, the laser signal derived height coordinate is output. During periods when the laser signal is not available, a corrected height coordinate value is generated by applying the height coordinate bias value to the satellite signal derived height coordinate.

Abstract: Disclosed is a signal analyzer that can receive a signal generated by an external system. The signal has a plurality of frequency components. The signal analyzer generates a suppressed phasor domain representation of the signal by selectively removing at least one component for use as a reference. The signal analyzer then displays the suppressed phasor domain representation of the signal. In one embodiment, the signal analyzer removes the component of greatest magnitude. The signal analyzer can also (or alternatively) remove a user selected component. In addition to the suppressed phasor domain, the signal analyzer can simultaneously display the frequency domain, the time domain, the numerical domain, and/or the modulation domain.

Abstract: Disclosed is a method and apparatus for determining the relative position of a mobile unit that moves from an initial location to a plurality of successive positions. The mobile unit receives signals from a plurality of navigation satellites and tracks the carrier phases of the signals during movement. For each of the received signals, carrier phase increments are calculated over a plurality of epochs. Anomalous carrier phase increments are determined and eliminated from further calculations. The non-eliminated carrier phase increments are then used to calculate coordinate increments for each of the time epochs. If, after elimination, the remaining number of carrier-phase increments is less than a threshold for a particular epoch, then coordinate increments for the particular epoch may be extrapolated using data from prior epochs. In various embodiments, least squares method and Kalman filtering may be used to calculate the coordinate increments.

Abstract: A method for detecting a preinjection in an internal combustion engine with a common-rail system, including individual accumulators, in which an individual accumulator pressure distribution is detected in a measurement interval and is used to determine an injection end of the main injection, in which a virtual injection start of the main injection is computed by a mathematical function as a function of the injection end, and in which the virtual injection start is set as the actual injection start of the main injection. With the preinjection activated, an actual injection delay for the main injection is determined as a function of the actual injection start, an injection delay deviation of a set injection delay from the actual injection delay is computed, and the injection delay deviation is used to determine whether a preinjection has occurred.

Abstract: The invention concerns a controlling and/or monitoring device, comprising a plurality of peripherals (Pa, Pb, Pc, Pn), a central control unit (4) and a communication network (5) connecting the central unit (4) to the various peripherals (Pa, Pb, Pc, Pn). The central control unit (4) comprises one or two transmission controllers (41, 42) connected to the various peripherals through a transmission channel (50), each transmission controller (41, 42) comparing context codes (Ka, Kb, Kc, Kn) received from the peripherals with stored reference codes (Ra, Rb, Rc, Rn) to set a security circuit (6) in a security configuration or in a fault configuration, depending on whether or not the compared codes show identical one-to-one correspondence.

Abstract: A device and method is disclosed for creating a customized chinrest for a violin or a viola, molded to conform to the precise idiosyncrasies of a player's chin and jaw, rendering greater comfort, support, range of motion, and control to the player. The chinrest of this invention is comprised of a rigid, flat, edgeless base upon which a removable, firm, but flexible silicone, custom molded top is adhered. The method of impression taking records complex contours, angles, and a range of motion created by head pivot of the player's chin and jaw while in the act of playing.
