Abstract: A microwave heating apparatus is used for heating a chromatographic column assembly containing a microwave absorbing material. The microwave heating apparatus includes an antenna transmitting a microwave signal and a resonant cavity containing the chromatographic column assembly and the antenna. The chromatographic column assembly extends relative to predetermined electromagnetic field strength contours within the resonant cavity to provide a predetermined heating profile along the length of the chromatographic column assembly. For example, a single-mode chromatographic column microwave oven can be used to heat a coiled chromatography column to a desired temperature gradient along its length. Oven design embodiments utilizing coaxial transmission line structures, coaxial resonators, and cylindrical resonators are described. To control the electromagnetic field gradient in the axial direction, the oven designs provide for varying some part of the oven geometry in the axial direction.

Abstract: A system for producing virtual camera motion in a motion picture medium in which an array of cameras is deployed along a preselected path with each camera focused on a common scene. Each camera is triggered simultaneously to record a still image of the common scene, and the images are transferred from the cameras in a preselected order along the path onto a sequence of frames in the motion picture medium such as motion picture film or video tape. Because each frame shows the common scene from a different viewpoint, placing the frames in sequence gives the illusion that one camera has moved around a frozen scene (i.e., virtual camera motion). In another embodiment, a two-dimensional array of video cameras is employed. Each camera synchronously captures a series of images in rapid succession over time. The resulting array of images can be combined in any order to create motion pictures having a combination of virtual camera motion and time-sequence images.

Abstract: A codec supports PCM modem communications (e.g., V.90, X2, or K56flex protocols) over a universal digital loop carrier (UDLC) having an analog interface to the central office (CO). The codec includes an analog-to-digital converter (ADC) that is synchronized to the CO clock, and an equalizer that has been trained to provide a transfer function to compensate for the distortion introduced by the CO line interface reconstruction filter and connecting circuits, to minimize resampling error. The features allow the codec to output a PCM stream that accurately reproduces the PCM data at the central office, at data rates sufficient to support PCM modem communications, as well as voice and conventional modem communications.

Abstract: A method of operating of controller-based progressive gaming system having a plurality of gaming machines wherein each gaming machine generates unit bet information indicative of a number of unit bets supplied to a machine for playing a game. The method comprises the steps of randomly selecting a bonus mode activation value between a high and low limit, providing a current value, providing a base value, incrementing the current value when the gaming machines are played so that the current value is incremented by a fixed amount of each unit bet received by each gaming machine. A bonus mode time period is entered when the incremented current value is equal to or exceeds the bonus value. Eligible machines are locked-in and random bonus jackpots are made during the bonus time period. Each bonus award decrements the current value by the amount of each award and the bonus mode time period is ended when the current value is less than or equal to the base value.

Abstract: A Pachinko bonus game system for an underlying game machine. The Pachinko bonus game has a playing field with a plurality of rows of pegs. A ball is launched onto the playing field by a launch mechanism when an initiate condition occurs during play of the underlying game. A row of lanes are provided on the playing field. The ball, after traversing among the pegs on the playing field, eventually travels through one of the lanes. At each lane is randomly displayed a bonus payoff value. The lane the ball travels through senses the presence of the ball and the value displayed for that lane is added to the credit meter in the underlying game. The bonus payoff values are randomly changed from game to game which eliminates any mechanical bias present in the Pachinko game. A stand-alone Pachinko game as well as using a Pachinko game as a coin dispenser is also provided.

Abstract: A programmable wavelength router having a plurality of cascaded stages where each stage receives one or more optical signals comprising a plurality of wavelength division multiplexed (WDM) channels. Each stage divides the received optical signals into divided optical signals comprising a subset of the channels and spatially positions the divided optical signals in response to a control signal applied to each stage. Preferably each stage divides a received WDM signal into two subsets that are either single channel or WDM signals. A final stage outputs optical signals at desired locations. In this manner, 2.sup.N optical signals in a WDM signal can be spatially separated and permuted using N control signals.

Abstract: A system for modifying job control language (JCL) parameters optimizes data storage allocations for datasets by collecting historical data concerning actual data storage space requirements and use patterns for each dataset. JCL statements are parsed to find references to datasets and their requested data storage space allocations. The system then generates revised JCL statements with revised space allocation requests and dataset migration information for each dataset based on historical space requirements and usage patterns. Optionally, the system can display each proposed change to the JCL statements for approval by the user. The system can also revise JCL statements requesting allocation of space for each dataset in predetermined data storage areas grouped by predetermined size ranges. Alternatively, some operating systems include a JCL interpreter that translates JCL statements into control blocks having predetermined parameter fields.

Abstract: An apparatus enables a conventional bicycle to be interfaced to a computer to serve as a controller for electronic games and the like. The apparatus includes a rear wheel support that removably holds the bicycle in an upright position while allowing rotation of the rear wheel. A rear wheel sensor detects rotation of the rear wheel of the bicycle as the rider peddles and generates an electrical signal indicating the rotational speed of the rear wheel. The apparatus also includes a front wheel sensor that detects the direction of the front wheel of the bicycle for the computer through the computer interface. For example, the front wheel of the bicycle can be removably supported by a front support member that rotates about a vertical axis as the front wheel is turned by the handle bars. A potentiometer is used to measure rotation of the front support member, and therefore the direction of the front wheel of the bicycle.

Abstract: Contrast agents developed specifically for x-ray diagnostics provide dose-enhanced radiotherapy and radiosurgery. The presence of heavy elements from these contrast agents, even small quantities, leads to a major dose increase in target tissue. When combined with in vivo calibration of the amount of contrast agent, the procedure is quick, accurate, and safe. The technique can also be used in combination with other techniques, such as focused x-rays, to achieve further enhancement of therapeutic ratio. Through optimization of the equipment it is possible to achieve very large ratios of dose in target to dose in healthy tissue up to 10:1.

The game table system of the present invention includes a sensor located at each bet region for detecting the value of the ante placed by the player at that location, a reader identifying each card dealt during the play of the game to the player and to the dealer, a computer connected to the sensor and the reader and the progressive jackpot for adding a predetermined percentage of the value of the ante to the progressive jackpot when a predetermined game event (such as the dealer going bust during the game of blackjack) occurs while preserving the value of the ante during the conventional play of the game.

Abstract: A system for dealing with faults in wavelength division multiplexed (WDM) optical communications between two terminals connected by at least two optical fibers monitors the status of communications over both optical fibers. If both optical fibers are operating normally, a first set of channels is routed over the first optical fiber and a second set of channels (which is mutually exclusive of the first set of channels) is routed over the second optical fiber. However, if a fault is detected in either optical fiber, the first terminal combines the first and second sets of channels and routes the combined channels over the remaining optical fiber to the second terminal. The second terminal separates the combined channels to recreate the first and second sets of channels. Wavelength slicers can be used to multiplex and demultiplex the channels at both terminals. This architecture allows the first and second sets of channels to be interdigitally spaced.

Abstract: A control system stabilizes the flexible body bending modes of a space, airborne, or ground-based system, while providing angular position control of an oscillating mass connected to a counter-oscillating counterbalance. The actuating mechanism uses two drive motors to exert torques on the mass and counterbalance, respectively, under the control of a feedback controller. The controller has a first control channel generating a first torque command signal for the first drive based on the angular position of the mass, and a second control channel generating a second torque command signal for the second drive based on the angular position of the counterbalance and a torque cross-feed signal from the first control channel. The second control channel includes a notch filter for removing input frequencies in a predetermined bandwidth about the frequency of the first torque command signal.

Abstract: A new class of x-ray optic suitable for use in x-ray proximity lithography employs many mirror facets arranged in a grazing incidence geometry at a relatively large distance from the mask. Each mirror facet is substantially flat in that its radius of curvature is substantially larger than the target. Each facet creates an optically independent channel that covers the entire target. The facets are arranged so that many channels can simultaneously illuminate the target, thereby achieving high flux at the target with high uniformity. Constraints on local and global divergence at the mask are met by making the optic sufficiently small and placing it sufficiently distant from the target.
