Inventor: AVRAMIDIS STELLIOS A
IPC: F16G13/04
Filed: 1990-02-26
Abstract: A power transmission chain (12) having a plurality of pin connected articulating and guide ranks (18) wherein each rank may include plain links (20) having a thickness that may vary from rank to rank. A group of plain links having a preselected thickness (A) is disposed in articulating ranks throughout the chain. Other groups of plain links having a different preselected thickness (B) are disposed in nonarticulating ranks of the chain. The combination of different thickness plain links disposed in a preselected manner coupled with elastic guide links throughout the chain is effective to minimise wear. The groups of plain links having preselected but different thicknesses cooperate with different thickness guide links (26) therein so as to improve load distribution thereacross, achieve equal deformation between the plain links and the guide links and maintain the transverse connecting pins (38) substantially parallel to each other. The plain links in this chain which are of the two toe variety are characterized by having nonidentical   toes (30,32). As a result of this difference, the dimensions from the center of the pins to the working surfaces of each toe vary with the result being that the timing between successive link and sprocket tooth engagements can be varied.

Title: System with a multi-function optical disk and drive for it
Inventor: CURTIS HOYLE L
IPC: G11B11/105
Filed: 1990-10-10
Abstract: Disclosed is an apparatus and method for defining magneto-­optical disk media (200) and an optical data storage device (126) that allows the media (200) to be convertible from writable to read-only. The media (200) has a media descriptor table contained within a control track (204) which is modified to define the media as a new media type. Previously manufactured drives will not recognize the media type, and therefore, will not read or write the media, so the data on the media is protected from being destroyed by such drives. The invention also defines a storage state bit within each sector of each track of the media, that defines whether the sector is writable or read-only. With this bit set into the writable state, the sector can be written many times. Once the bit is changed to read-only, however, the sector can no longer be written. The data storage device of the invention will not reset the bit, once it is set to the read-only state. The invention defines two locations for the storage state bit. In one embodiment of the invention the storage state bit is located in the sector mark field area of each sector, prior to the data portion of the sector. In a second embodiment of the invention, the storage state bit is placed in the data field area of each sector. Using the above described apparatus and method, the invention provides the same level of security as current WORM drives.

Abstract: Disclosed is a switch (116) that allows a peripheral device (106), such as a printer, to be shared by multiple computer systems (102,108). The switch (116) connects to each of the computer systems (102,108), and also to the peripheral device (106) being shared. The switch (116) stores the current state of the peripheral device for each to the computer systems (102,108), so that when a particular system requests access to the peripheral device (106), the switch can restore the state of the peripheral device to the last state established by the system requesting usage.

Abstract: A device for aligning a plane of polarization includes a birefringent crystal plate (3) and a polarizing filter plate (4). A beam of an incident linearly polarized light (7) having any direction of polarization is launched from an incident side optical fiber (1) and introduced through an incident side collimator (2) into the birefringent plate (3), which in turn splits the incident beam into two beams of light component linearly polarized (9, 10) and propagating in respective directions substantially perpendicular to each other. The two beams (9, 10) are introduced into the polarizing filter plate (4) and only a component of light linearly polarized is extracted that has a direction of polarization corresponding to the direction (20) in which light is passed and polarized in the polarizing filter plate (4). This is outputted to an output side optical fiber (6) through an output side collimator lens (5).

A container (10) having a closed bottom and sides and open top contains the powdered toner. The powder is fluidized by introducing air (at 11) through a pervious closed bottom (13) of the container and by vibrating the container. The toner is simultaneously stirred and electrically charged to a potential of greater than about 7kv (plus of minus polarity) by rotating elements 14) with radial pointed appendages in the container. Toner is transferred from the container to an image cylinder (41) at an exposed nine o'clock position of the image cylinder by a plurality of transfer cylinders (30). A first transfer cylinder (31) is mounted so that its periphery is just above the open top of the container and an applicator cylinder (33) has its axis below the axis of the first cylinder and its periphery adjacent both the first cylinder (31) and the image cylinder (41). A second cylinder (35) is for the removal of opposite sign charged toner and low charge toner from the applicator cylinder. Scrapers (32, 34) scrape unused toner from the first and applicator cylinders so that it falls into the open top of the container. A hopper (20) supplies fresh toner.

Abstract: Shapes are compared by obtaining a measure of dissimilarity based on near neighbor data. First, an image of one shape is analyzed to obtain, for each pixel position, a distance to the nearest pixel that meets a criterion, such as being a black pixel. Then, a sum of distances is obtained by totalling the distances of the pixel positions at which an image of another shape meets the criterion. The sum indicates dissimilarity. The near neighbor distances and sum can be obtained by hierarchical operations.

Abstract: The calibration cuvette apparatus for storing and calibrating a chemical sensor in a tonometered solution includes an upper cuvette section and a lower cylindrical valve section for alternatively sealing the cuvette section and admitting a gas mixture to the cuvette section. The upper cuvette section has relatively narrow diameter upper and lower ends on either side of a wide diameter middle portion. The cuvette section is adapted to receive the sensor and retain the sensor in a fluid bath in the cuvette section so that the chemical sensor portion is disposed approximately in the center of the wide middle portion of the cuvette section. The chamber formed within the cuvette section is thus shaped so as to maintain the sensor in a position in the fluid bath so that any gas bubbles within the chamber will not dry the sensor. A lower end portion of the cuvette section includes a gas communication inlet for introducing gas into said chamber to equilibrate the tonometered buffer solution.

Abstract: A buffer/quantizer controller (110) in a video coder (100) utilizes the average quantization step size employed for the previous frame, the average number of bits produced per pel by the video coder for the image contained in the previous frame and the current frame buffer (108) fullness level to obtain an indication of image complexity. A target current frame quantization step size to be employed by the video coder in encoding a current frame is based on the indication of image complexity. Optionally, the target frame quantization step size is adjusted by a mapping procedure, at predetermined intervals within each frame period, to account for the current buffer fullness. The map employed by the mapping procedure is adjusted in accordance with the target frame quantization step size.
