Abstract: A hydrostatic module is disclosed, including a pair of shafts rotatably supported by a frame. Two yokes are pivotally mounted on the frame, each having complimentary surfaces to the other yoke and to the frame, minimizing the space occupied by the yokes. Stop means are provided on the yokes and on the frame to limit the pivotal movement of the yokes. A hydrostatic power unit is carried by each yoke, each connected to one of the shafts. A control system, having a single piece control housing containing servo pistons, pivots the yokes. The servo pistons independently determine the orientation of the yokes. A single piece fluid control porting plate is secured to the control housing to route hydraulic fluid to multiple locations within the control housing. A fluid manifold serves as a main structural element, with intimate proximity between the manifold and the control housing allowing simplified fluid exchange therebetween.

Abstract: A ladder suspension bracket releasably receives and suspends a portable ladder for use, storage, and transportation if on a vehicle (FIG. 1, FIG. 7) comprising of a receiving bracket (FIG. 4, or FIG. 8) and a lower distance maintenance bracket (FIG. 5, or FIG. 9) optionally pivotable (45, 46) to hold step ladder substantially away from the ascension surface (49) or horizontal (5) as required for the ladder type. Bracket is configured such that ladder can easily be released of suspension mode (FIG. 7, FIG. 2) and used independent of this mounted position (FIG. 3). In addition to the claim of such a bracket a ladder having intentional configuration (2) to provide for suspension is also claimed, as is the combination thereof.

Abstract: The present invention relates to the design of libraries, such as combinatorial libraries, which may be used in the discovery of novel potentially useful compounds. The invention operates on a population of libraries that is refined iteratively. The refinement involves the following steps: calculating the relative dominance of the libraries in the population; selecting libraries for modification according to dominance; modifying the selected libraries using genetic operators; and inserting the modified libraries back in the population. The refinement steps are repeated until adequate convergence is deemed to have occurred or for a specified number of iterations. The Pareto optimal set of libraries in the final population is output for further processing such as storage or manufacture.

Abstract: A head structure for writing data on a magnetic media including a first pole having an upper surface and a write gap covering a portion of the upper surface. An upper pole tip formed on the write gap having a first width. A second pole having a second width greater than the first width and coupling to an upper surface of the upper pole tip. A conductive coil magnetically coupled to the first pole and the second pole to induce magnetic flux within the first and second pole in response to a current flowing in the coil.

Abstract: A system for managing replacement of x-ray tubes, such as in medical diagnostic systems, includes circuitry for monitoring operating parameters of the x-ray tubes, and circuitry for analyzing the monitored parameters and scheduling for tube replacement based upon predicted failure. The scheduling circuitry may be located in a remote service center and is linked to the diagnostic systems via a network connection. A failure prediction circuit may be located at the remote service center or local to the diagnostic system. Upon identifying a predicted tube failure, replacement of the tube is scheduled and shipment of a replacement tube is ordered. Service personnel may be notified automatically to coordinate tube replacement. Electronic messages may be transmitted to the service personnel and to personnel in the facility where the x-ray tube is installed to notify all parties of the scheduled tube replacement.

Abstract: A driver chip for use in an LED or other multi-element recording printhead includes a plurality of current driver channels. Data for determining recording durations for each of the current driver channels is provided on a data bus. A token bit is shifted through a shift register in association with image data to be latched by registers corresponding to a specific driver channel. The driver chip is operational in different recording resolution modes so that it may be connected to recording arrays of different resolutions. When operational in other than its highest or higher resolution, a by-pass signal is generated causing the token bit to by-pass certain stages of the shift register.

Abstract: A non-impact printhead having a plurality of driver IC chips and and a plurality of recording elements such as LEDs. Each driver IC chip includes a plurality of current-carrying channels that are operative for carrying current to respective recording elements on the printhead and a control for controlling operation of the driver.

Abstract: A method for connecting selected bonding pads of a universal current driver IC supporting a maximum resolution, e.g., 600 DPI, with the appropriate bonding pads of the same or a lower resolution LED chip array. The output pads of the current driver IC and the pads of the LED elements of each LED chip array or segment are matched so that wire bonding takes place between the physically closest pads. Consequently, the universal current driver IC may be employed with LED chips or segments of a certain standardized length that contain 96 LED elements for 300 DPI, 128 LED elements for 400 DPI, and 192 LED elements for 600 DPI or the like. The selection algorithm, in picking the physically closest IC current driver pad to be connected to an LED element pad leaves certain stages of the IC driver unconnected.

Abstract: In an LED printhead or the like, a plurality of LED arrays are arranged in a row. Opposite the LED arrays are driver IC chips providing current in respective current driving channels to respective LEDS. Current to an LED for recording of a pixel will be provided for say a duration related to a multibit image data signal. A data bus is provided for carrying the data signals. The data signals are latched in respective data registers associated with each current driving channel. A token bit shift register is provided for identifying a respective data register for latching of the multibit image data signal presently on the data bus. A direction of shifting of the token bit is determined through automatic self-sensing of the token bit itself as the token bit is moved from a boundary scan register that forms a part of a boundary scan test architecture.

Abstract: A method for producing a calibrated printhead having a plurality of light-emitting recording elements such as LEDs includes the steps of (a) burning-in the recording elements until a further aging characteristic of the recording elements is in a generally linear range; (b) measuring a light intensity emitted by each recording element after the burning-in in step (a); (c) establishing a target value for additional burning-in of at least those recording elements having measured light intensities above a minimum measured light intensity for a recording element; and (d) respectively providing additional burning-in to those recording elements towards the target value. An apparatus including the calibrated printhead has no data provided to the printhead which is corrected for relative non-uniformity of the recording elements to each other.

Abstract: A support substrate having an array of magnetically responsive sensors is mounted within the housing of a brushless DC motor in a plane perpendicular to the axis of the motor shaft having commutating magnets thereon. A ferromagnetic flux concentrating member in the form of a generally planar disc having an annular rim with radially inwardly directed spokes is mounted to the support substrate. Each spoke has a radial gap therein. A magnetically responsive sensor is received within each radial gap. The gap may divide the spoke into two discrete gap segments, or may alternatively form an enclosed recess with generally radially extending sidebars along each lateral edge of the spoke.

Abstract: An energy monitoring arrangement that is operatively associated with a centrifuge instrument monitors the magnitude of applied accelerating energy that is used to accelerate a rotor and to interrupt the continued application of accelerating energy if the magnitude of the applied accelerating energy exceeds a predetermined reference energy value. Preferably, the net applied accelerated energy to the rotor is monitored and used in the comparison with the energy reference. The invention may also be used in a predictive manner to provide, early in the centrifugation run, an indication of the energy of a rotor at an operator-ordered set velocity.
