Patent CA-1269145-C (CA)
Title: Radiant beam coordinate detector system
Inventor: GOLBORNE CARLOS E
IPC: G06F3/033
Filed: 1985-11-08
Granted: 1990-05-15
Abstract: ABSTRACT RADIANT BEAM COORDINATE DETECTOR SYSTEM A crossed light beam coordinate detection and encoding system having a plurality of emitter/detector pairs along each axis of the display space is disclosed. The emitters are modulated in amplitude and the detectors are biased with a low load resistance to provide a wide dynamic range. The wide dynamic range and amplitude modulation detection provides immunity to unwanted interference. After band pass filtering, the carrier is amplified by high gain amplifier with auto bias control. The output of the amplifier generates a true/false output corresponding to the presence/absence of a beam. A single chip microprocessor controller checks the screen for interrupted beams and when not clear generates coordinates of the interrupted beams. The coordinates can be calculated as a weighted average of the interrupted beams for each axis or as the min and max coordinates along each axis. Reporting is done repeatedly at preselected time intervals. Error information is generated each time the coordinates are generated to report errors such as too large or too small an object or a discontinuous object. Repeated reportings beyond the initial reporting of a coordinate of the interrupted beams can be locked out in response to the position of the interrupted beams in the display space. Diagnostics of the system can be performed at 100% and 90% output levels of the emitters. This allows diagnostics to detect marginal operation of the screen.

Granted: 1990-04-24
Abstract: Abstract of the Disclosure A driver assembly for the pad of a high speed floor burnishing machine includes a flexible backing plate having a peripheral retaining skirt which centers the pad on the driver assembly and also prevents the edges of the pad from growing or expanding to a larger circumference during high speed rotary burnishing action. The backing plate adds stiffness to the pad when rotating at high speed, and it promotes uniform contact of the pad with the floor at the outer radial extremities of the pad where the velocity is greatest and the polishing is most effective. In the illustrated embodiment, the pad and driver assembly are surrounded by a shroud which is continuously evacuated by radial air flow generated by the motion of the driver assembly which includes a finned hub. The air flow carries debris generated by the burnisher to a collection bag or filter without leaving the machine.

Granted: 1992-01-14
Abstract: ABSTRACT           An improved electronic particle counter is described in which the electrodes and at least part of the signal processing circuitry are integrally formed on the pane in which the orifice is located.  The pane is formed from a wafer of sapphire of the grade  customarily used in the manufacture of silicon-on-sapphire integrated circuits.  A silicon layer is first formed epitaxially on one side of the wafer and integrated circuits are then formed in the silicon layer using conventional photolithographic techniques. illustratively, the integrated circuits provide the same particle counting and particle sizing functions that are available in separate packages with state-of-the-art particle counters.  An electrode is formed on the same side of the wafer as the integrated circuit by converting some of the epitaxial silicon to a conductive polysilicon or by depositing a metallic layer; and the electrode is connected to the signal input lead of the integrated circuit.  A second electrode is then formed on the opposite surface of the wafer by deposition of a metallic layer.  An orifice is formed in each pane in the sapphire by etching or drilling.  Finally the wafer is diced so as to separate the individual panes.
