Title: Method and apparatus for enhanced ion spectra generation and detection in ion mobility spectrometry
Inventor: SPANGLER GLENN EDWARD
IPC: G01N27/62
Filed: 1990-04-09
Granted: 2000-06-20
Abstract: A method for operating an ion mobility spectrometer in which an analyte sample is ionized in the spectrometer reaction chamber, and the analyte ions are permitted to flow freely from the reaction chamber into the spectrometer drift chamber. The ion current output from the spectrometer ion current detector is observed during this time. The ion flow from the reaction chamber to the drift chamber is then momentarily interrupted, and the time delay between the time of ion flow interruption and the appearance of a decrease in the ion current detector output is observed. Difference substances are characterized by different delays. The concentrations of the different substances may be determined by measuring the change in detected ion current after the ion flow interruption.

Title: Calibration system and method for color image scanning
Inventor: SMYTH WILLIAM K
IPC: H04N9/09
Filed: 1990-06-25
Granted: 2000-08-29
Abstract: A system and method for calibrating signals provided by individual cells in a photodetector array scanned by light originating at a low-cost variable light source and reflected from a subject to be replicated in digital form by processing photodetector cell signals in a manner so that individual cell signals are corrected to compensate for fluctuations in source light. The system and method is particularly applicable to a color balanced photodetector array in which individual photodetectors are arranged in sets with each set having a variable number of rows oriented in a direction transverse to the direction of scan and columns parallel to the direction of scan.      The invention is practiced by exposing the first few photodetectors in each row to the full spectrum of visible light reflected from a white reference patch.      During processing, as the photodetector signals are sequentially transferred, to a processor, the signals provided by the cells exposed to the white reference are compared with a fixed value to obtain a calibration factor. As the signals develop by cells in the same set but as a result of exposure to light reflected from the subject image, those signals are multiplied by the calibration factor so that the process signals are corrected for variations in source light on a real time basis.

Granted: 2003-10-14
Abstract: Continuous forms (e.g. computer paper with individual sheets separated by perforations) of one job are automatically folded and separated from the forms of the next job. Detectable marks are printed within a window onto the first form of one job, or the last of another, in a first mode, or the forms are counted in a second mode. The marks within the window are sensed by an LED sensor, which feeds information to a computer (microprocessor) control.      The computer control effects operation of a cutting blade to sever the last form of one job from the first form of the next. The forms are automatically folded in a festooning action by a Bunch folder.      Hall effect sensors are mounted for cooperation with notched discs on he same shaft as beaters of the Bunch folder, and function as end of travel limit switches for the folder swing chute, to provide relevant data to the microprocessor for proper operation of the cutting blade.
