  • Publication number: 20190290315
    Abstract: A direct stream hydrodynamic catheter system is provided for the removal of thrombus, lesions and the like including provisions for the infusion of drugs, lysing fluids and the like into a blood vessel. Physician controlled powered direct fluid jet streams emanate from a fluid jet emanatory in the form of robust radially directed fluid jet streams to impinge upon and ablate difficult and strong thrombus and lesions within a blood vessel. Effluent aspiration is controlled by an exhaust regulator in the form of a roller pump, but effluent removal can be assistingly influenced by the fluid pressure associated with the radially directed fluid jet streams.

  • Patent number: 10393045
    Abstract: A method and system for initiating regeneration of a diesel particulate filter (DPF) within a diesel engine system comprising the DPF, a data link connector (DLC), and an electronic control unit (ECU) such as an engine control unit includes an engine communication interface (ECI) device and a communication device that request and transmit DPF inhibit parameters that indicate whether initiation of regeneration of the DPF can be performed. The ECI device can comprise two connectors that are connectable to different types of DLC. The communication device can comprise a smart-phone. The ECI device can determine which DPF inhibit parameter are to be requested from the ECU and which vehicle communication protocol is required to communicate with the ECU. The communication device can receive the DPF inhibit parameters, determine whether initiation of regeneration of the DPF can be performed, and transmit a communication to request initiation of regeneration of the DPF.

  • Publication number: 20190196216
    Abstract: A device (100) for speckle reduction, comprising an optical cell (110) and a controller (130). The optical cell (110) comprises a first and second cell wall (121, 122) spaced apart by a gap, and a liquid crystal composition (114) in the gap. The controller (130) is configured to cause fluid turbulence in the liquid crystal composition. The fluid turbulence in the liquid crystal composition (114) results in time varying spatially random scattering of light (102) transmitted through the liquid crystal composition (114). The liquid crystal composition (114) has a chiral nematic phase.

  • Patent number: 10240643
    Abstract: A self-contained clutch for diesel engines for off-highway implementation is provided. A stationary friction disc, pressure plate and endplate sandwich a pair of rotating separator discs. Attenuation of vibration damping of the rotator discs may be achieved by a centrifugal weight. A pulse-width-modulated DC motor or valve is employed in association with a hydraulic actuator to control pressure to the clutch piston. An RFID tag uniquely identifies the nature and parameters of the clutch itself and is associated with the clutch such that the controller can most efficiently operate the clutch. Heat is dissipated by an oil pump servicing the support bearings and/or by the integration of a centrifugal fan into the heat disc stack.

  • Publication number: 20150129333
    Abstract: A selectively powered transport device such as an ambulatory stretcher-chair is presented. The stretcher-chair has a spring-biased Hall-effect mechanism controlled by an operator to command a desired direction and speed of mobility of the device. A power drive control unit senses a target direction and speed of movement and incrementally closes on that target. The power drive control unit senses the presence of ramps or inclines by monitoring instantaneous current to a drive motor and adjusts the motor operation accordingly. The power drive control unit further monitors thermal operational conditions of the drive motor by monitoring motor winding current and assessing energy dissipated as heat in the motor winding as a function thereof. The net accumulated heat energy associated with the motor is monitored and corrective action with respect to the current applied to the motor is taken accordingly.

  • Publication number: 20010052272
    Abstract: A process is provided for the production of titania rich slag from ilmenite. The ilmenite is fed together with carbonaceous reductant, and in the absence of fluxes, to the molten bath of a DC arc furnace. The molten bath of the furnace forms the anode and one or more electrodes in the roof of the furnace forms the cathode. A frozen lining is established and maintained between the refractory lining of the furnace and the molten bath and the process includes means to control the thickness of the frozen lining as well as the whole smelting process.

  • Patent number: 6150778
    Abstract: A system for detecting the position of a rotor for a switched reluctance (SR) machine having an irregular pole configuration. The system does not require the use of a conventional sensing device, and provides accurate position information, without disrupting operation of the machine. A voltage ratio is used to infer the position of the rotor relative to the stator.

  • Patent number: 6137256
    Abstract: A circuit for controlling the operation of switched reluctance machines (i.e., motor or generator) having a plurality of phase windings. The circuit slows down the initial "turn off" of the phase windings to eliminate an abrupt reduction in the current flowing therethrough. This reduces the impulse which excites mechanical oscillations in the motor/generator, reduces switching losses in the switching transistors, and reduces the number of harmonics.

  • Patent number: 5505543
    Abstract: Method and apparatus for measuring thermal radiation emitted by a sample, and for determining emissivity. The apparatus comprises a chamber in which the sample may be positioned, the chamber comprising a plurality of walls including a first wall containing an observation port. The chamber is located in a cold environment, and the walls of the chamber are brought to a selected temperature by circulating a temperature conditioned fluid through the walls. The sample is moved along a movement axis within the chamber past the observation port. As the sample is so moved, radiation emitted outwards through the observation port by the sample is measured.

  • Patent number: 5150170
    Abstract: Apparatus and method for determining velocity and range of a target within a field of view. A velocimeter and tracker (10, 100) includes a laser (12, 12') that produces modulated coherent light, a portion of which illuminates targets (22, 22') coming into a field of view (24, 24') of the velocimeter and tracker. Coherent light reflected from the target travels back along a detection path toward a phase conjugate mirror (40, 40') as a probe wave (26, 26'). A higher intensity portion of the coherent light produced by the laser is split into equal parts that are directed toward the phase conjugate mirror from opposite directions and interact with the probe wave to produce a phase conjugate light signal that travels back along the detection path and is also reflected from the target. Light reflected by the target experiences a Doppler phase shift as a function of target velocity.

  • Patent number: 5093834
    Abstract: Four-wave mixing is used to produce a steered optical phase conjugate wave. First and second pump waves are combined with a probe wave in a nonlinear medium within an optical conjugate, producing an optical phase conjugate wave. The magnitude of the wave vectors corresponding to the first and second pump waves are different, causing the optical phase conjugate wave to define a non-zero angle .theta..sub.0 relative to the probe wave. In a first embodiment, the wavelengths of the first and second pump waves are controlled to vary the angle, while in a second embodiment, the intensities of the two pump waves are modified.

  • Patent number: 4972186
    Abstract: A resolver driver circuit uses sine and cosine values stored in a read only memory to generate sine and cosine waveforms by sequentially reading the stored values and passing them through a clocked data latch to a digital-to-analog converter. The output of the digital-to-analog converter is filtered to remove quantization error. Phase error produced by the filtering and other sources is detected by timing the zero crossings of the sine and cosine waveforms and comparing them to a master synchronization signal. Phase error is corrected by controlling the timing of the latch which passes data to the digital-to-analog converter.
