Granted: 1995-12-26
Abstract: A conversion replacement apparatus for HID screw-in mercury vapor, metal halide or high or low pressure sodium lamps utilizes the reflector typically employed with such lamps.  The HID lamp is removed from the reflector.  A fluorescent lamp support frame then is attached to the base end of the inside of the reflector to extend to a point substantially one-fourth to one-half of the distance between the base end and the light-emitting end of the reflector.   The support includes a plurality of extensions for holding the bases of compact fluorescent  lamps arranged  in a general star configuration around the center line of the reflector. The  extensions  are  bent  at  an  angle  to  cause  the  compact fluorescent lamps to follow the outwardly-flared inside surface of the reflector.  Ballasts for the lamps are located in a housing attached to the base end of the reflector.  Additional controls are provided for selectively supplying power to different ones of the ballasts for the fluorescent lamps to effectively provide "dimming" of the overall light output from the fixture.

Title: Detection of bacteria in blood culture bottles by time-resolved light scattering and absorption measurement
Inventor: BERNDT KLAUS W
IPC: G01N21/59
Filed: 1993-03-30
Granted: 1999-12-21
Abstract: Methods and apparatus for detecting bacteria in samples using time-resolved light scattering and absorption measurement are disclosed. The present invention provides a system wherein a plurality of samples may be tested by providing a modulated excitation signal which is introduced into each sample and collected at a point disposed across each sample. The amplitude and phase of the collected signal are then processed to determine the time characteristics, modulation and phase of the signal after it has passed through the sample. By comparing this time characteristics, modulation and phase with the time characteristics, modulation and phase collected at a previous point in time or alternatively from a sample known to be free of bacteria, the presence of bacteria may be determined, since it has now been. found that the presence of bacteria causes a significant change in the time characteristics, modulation and phase. Preferably, diode lasers are used to introduce modulated electromagnetic radiation to the samples and a multichannel plate photomultiplier tube is used to provide a signal from which the phase and amplitude can be determined. Alternatively, in other embodiments of the present invention the modulated electromagnetic radiation may be introduced using an optical switch and the multichannel plate photomultiplier tube may be replaced by avalanche photodiodes disposed against each sample that also create a signal containing time-averaged intensity, amplitude, and phase information.      An improved optical switch is also disclosed.

Title: Programmable controller with fast i/o scan
Inventor: MEAD IAN D
IPC: G05B19/05
Filed: 1993-01-05
Granted: 1996-11-26
Abstract: A programmable controller (54) is disclosed for the purpose of controlling devices such as machine tools and other ma-chinery, and which is often mated with a host computer numerical controller (52). The programmable controller is configured such that certain users-designated "fast-scan" outputs can operate at much higher speeds than non-designed "normal" outputs, thereby greatly increasing the response time and efficiency of the operations that are controlled by those fast-scan outputs. the programmable controller uses a processor which scans through its user-definable program (including the value of all system in-puts and outputs) before it attempts to change the value of any of its outputs. The physical input/output (I/O) interfaces are lo-cated on I/O racks (60) each of which also includes an intelligent bus adaptor (70). The intelligent bus adaptor includes its own processor which periodically communicates with the processor in the programmable controller. The intelligent bus adaptor's pro-cessor controls the fast-scan output located on that particular I/O rack within very short time intervals, and allows for a response time that is an order of magnitude faster than the response time of normal outputs of the programmable controller.

Granted: 2001-06-12
Abstract: A method and apparatus for minimizing the effect of lateral velocity transients upon an aircraft inertial instrument calibration process of the type in which cross-track velocity is measured and utilized to correct for the east component of gyro bias error. A "cross-track position" value is obtained by integration of the cross-track velocity. A Kalman filter calculates a plurality of gain values corresponding to measurements of crab angle, lever arm, north and east velocity, heading angle and rate of change of heading angle and those gain values are applied to the cross-track position value to obtain error values for each of such parameters. The calculated error values are then employed as corrections to, or calibrations of, the inertial instrument outputs.

Title: Sheet processing system with neural network control
Inventor: CHROSNY WOJCIECH M
IPC: B65H7/06
Filed: 1993-10-07
Granted: 2005-01-25
Abstract: A sheet processing apparatus, which may be a mailing machine, inserter or similar system for producing mail pieces or may be a copier or printer or the like. The system includes a control mechanism for reducing the likelihood of jams as sheets are fed through a sheet handling apparatus included in the system. Preferably the control mechanism will include a neural network trained to response to a characteristic signal generated by a sheet feeder as a sheet is input to the apparatus. After training the network will produce a control signal output for controlling the processing rate of the apparatus to reduce the rate if there is a likelihood that the input sheet will jam. The network may also produce an outstacking signal for diverting sheets, in extreme cases, for corrective action. The drive current of a motor used to output the sheet from a sheet feeder is monitored to provide the characteristic signal which is sampled an input to the network. And additional signal representative of an external condition, such as temperature or humidity or operating history may also be input to the network.

Abstract: A shifter for a manual transmission of a vehicle includes a shift stick configured to operably engage the transmission, and a base adapted for mounting to the vehicle and configured to pivotally support the shift stick for movement about first and second orthogonal axes. In particular, a trunnion is pivotally mounted to the base for movement about the first axis, and the shift stick is configured to pivotally engage the trunnion for movement about the second axis, the shift stick being configured to move with the trunnion as a unit when pivoted about the first axis. A plate spring is compressively mounted on the base and the trunnion is configured to operably engage the spring so that the spring biases the trunnion and shift stick to a neutral position about the first axis but so that the spring does not bias the shift stick when pivoted about the second axis. The trunnion is configured so that the second axis is located closer to the transmission than the first axis so that the shift stick provides more mechanical advantage when shifting about the second axis than the first axis.
