  • Patent number: 7710061
    Abstract: A motor control amplifier for position feedback control is provided utilizing the inherent inductor and/or resistor dynamics of the motor. The motor control amplifier applies a voltage to the motor equivalent to the electrical motor resistance multiplied by the current of the motor, canceling out the electrical motor resistance, and thereby providing position feedback control through motor inductance. A command term/voltage could be added to make the position feedback control relative to a setpoint. Further, a motor control amplifier for feedback control to arbitrary dynamics is provided. The motor amplifier applies a voltage proportional to a wave command signal. The motor amplifier has a sensing component to provide a wave return signal to construct a wave transformer from the electrical motor resistance.

  • Patent number: 7707486
    Abstract: A computerized spreadsheet system includes a set of cells and a separate set of logical constraints on the values of cells. The constraints may be many-to-many relationships that permit omni-directional propagation of values between cells. The constraints may be expressed in a language encompassing first-order logic. Cells are dynamically reclassified as base cells or computed cells as a user specifies values for cells. Non-explosive consequences of the base cell values are computed and displayed in computed cells, even when the values in the base cells are inconsistent with the constraints. The spreadsheet system may also include an auto-complete feature that automatically fills in empty cells with values consistent with the logical constraints and an auto-deconflict feature that automatically changes values in cells to reduce conflicts with the logical constraints.

  • Patent number: 7700218
    Abstract: A simple, inexpensive and highly efficient fuel cell has boundary structures made of a photo-sensitive material in combination with selective patterning. Printed circuit board (PCB) fabrication techniques combine boundary structures with two and three dimensional electrical flow path. Photo-sensitive material and PCB fabrication techniques are alternately or combined utilized for making micro-channel structures or micro stitch structures for substantially reducing dead zones of the diffusion layer while keeping fluid flow resistance to a minimum. The fuel cell assembly is free of mechanical clamping elements. Adhesives that may be conductively contaminated and/or fiber-reinforced provide mechanical and eventual electrical connections, and sealing within the assembly. Mechanically supporting backing layers are pre-fabricated with a natural bend defined in combination with the backing layers' elasticity to eliminate massive support plates and assist the adhesive bonding.

  • Patent number: 7694552
    Abstract: A mechanical resonator capable of providing an intrinsically high mechanical quality factor in immersion is provided. The resonator includes a membrane attached at its perimeter to a frame, such that a front side of the membrane is in contact with the liquid, and the back side of the membrane is not in contact with the liquid or the frame. The membrane can act as a mechanical resonator. The quality factor of this resonator is enhanced by providing a pressure release boundary region on the frame in proximity to the membrane and in contact with the liquid. The pressure release boundary region provides a soft boundary condition, in the sense that a mechanical impedance on the solid side of the solid-liquid interface is less than the liquid mechanical impedance. Providing such a soft boundary condition reduces the mechanical energy loss due to excitation of waves in the liquid, thereby improving resonator quality factor. Such high-Q resonators are particularly useful for sensor applications.

  • Patent number: 7683334
    Abstract: A phoswich radiation detector for simultaneous spectroscopy of beta rays and gamma rays includes three scintillators with different decay time characteristics. Two of the three scintillators are used for beta detection and the third scintillator is used for gamma detection. A pulse induced by an interaction of radiation with the detector is digitally analyzed to classify the type of event as beta, gamma, or unknown. A pulse is classified as a beta event if the pulse originated from just the first scintillator alone or from just the first and the second scintillator. A pulse from just the third scintillator is recorded as gamma event. Other pulses are rejected as unknown events.

  • Patent number: 7680212
    Abstract: A method, processor and system for linear precoding for a multiple-input communication channel described in terms of an effective mean and an effective correlation is provided. The effective mean and correlation can be the sample mean and correlation of the channel, or they can also include an estimate of the channel and a quality parameter of the estimate. The precode is derived by minimizing a Chernoff bound on the pairwise error probability. It is assumed the channel code is a matrix block code, which includes spatial multiplexing and space-time block codes (STBCs) as special cases. In some cases (e.g., an orthogonal STBC) the codeword separation matrix is a scaled identity matrix. In these cases, the precode that minimizes the Chernoff bound can be determined analytically. It may be necessary to perform a “dynamic water-filling” procedure in order to satisfy constraints on the optimization. In other cases, the codeword separation matrix is not a scaled identity matrix.

    Abstract: A nodule registration system useful for tracking lung nodules in computed tomography (CT) scans is presented. The system registers a small sphere centered on a detected nodule in one scan with another scan under a rigid transformation assumption using a fast registration scheme. The registration scheme employs very fast simulated annealing (VFSA) with constraints to maximize a tunable cross-correlation (TCC) coefficient, enabling the system to register, with minimal registration error, all nodules within their maximum diameter. The system achieves an average registration time of 10 seconds or less on a 3.06 GHz computer programmed to implement the present invention.
