US Patent:

49874292, Jan 22, 1991

Filed:

Jan 4, 1990

Appl. No.:

7/460735

Inventors:

Ronald B. Finley - San Francisco CA
Gene F. Day - Hillsborough CA
David J. Devine - San Jose CA

Assignee:

Precision Image Corporation - Redwood City CA

International Classification:

G01D 1506
G03G 2500

US Classification:

346157

Abstract:

A simplified color printing system and method is disclosed in which the printing system has a single applicator that is supplied with toner fluids or inks of different colors. The printing system is simplified by having a single pump employed in association with the applicator. Use of a single pump is made possible, because during a color change the pump and applicator are purged with air both before and after a wash fluid is circulated. The single pump is used to pump both the imaging fluids and the air. The present invention has application in both color electrostatic printers and copiers, and in color ink-jet printers.

International Classification:

G01R 3102

US Classification:

324 51

Abstract:

A test apparatus for locating electrical shorts that is especially suited for use while an electrical circuit is being fabricated or assembled. A ring counter derives input pulses from a squarewave oscillator. The outputs of the counter are fed through transistors to an array of light emitting diodes. Each diode is connected to an electrical conductor, such as a bus bar, that is to be tested. In the absence of a short between two electrical conductors the diodes are sequentially illuminated. When a short occurs, a comparator/multivibrator circuit triggers an alarm and stops the oscillator and the sequential energization of the diodes. The two diodes that remain illuminated identify the electrical conductors that are shorted.

Abstract:

Embodiments in accordance with the present disclosure are directed to configuring an analyzer apparatus for processing a particular sample-processing cartridge. The analyzer apparatus includes a portable container and sample-specific configuration circuitry. The portable container supports and integrates a sample-processing cartridge and the sample-specific configuration circuitry. The sample-specific configuration circuitry identifies configuration information specific to the sample-processing cartridge and configures the analyzer apparatus for a series of state configurations. The configuration can be performed by selecting which of a plurality of biological-sample stimulators to interact with the biological sample, identifying positions in the portable container for each of the selected ones of the plurality of biological-sample stimulators at different times, and while the selected ones of the plurality of biological-sample stimulators are in the identified positions, causing the interactions between the selected ones of the plurality of biological-sample stimulators and the biological sample.
