An apparatus for enhancing hygiene comprises a sensor for generating a first signal upon automatically sensing that an individual has entered a washroom and for generating a second signal upon automatically sensing that the individual has exited the washroom. The hygiene enhancing apparatus further comprises a monitoring device for automatically monitoring an individual upon his entry into the was...

A laser radar apparatus for producing a pulse modulated transmitted light beam and receiving reflected light beams from road mounted retroreflectors. In the preferred embodiment, a floodlight beam illuminates a portion of a roadway from 20 to 150 in front of a vehicle. Reflected beams from retroreflectors mounted in the roadway are received by the radar unit which calculates distance D and angle t...

A system which includes a microprocessor (or microcontroller) and an auxiliary chip which monitors the system power supply voltage and performs related functions for the microprocessor. In one mode of operation (for use with a low-power CMOS processor), the auxiliary chip sends an interrupt to the microprocessor when the power supply falls to a first level, and also resets the microprocessor when ...

Title METHOD AND APPARATUS FOR INSURING OPERATION OF A MULTIPLE PART SYSTEM CONTROLLER Inventor John L. Hartman In a system controller having multiple parts including a microprocessor, a main program for execution upon the microprocessor, and at least one clock interrupt handler portion, a method and apparatus for insuring proper operation comprised of providing a main counter and a delay counter ...

In one broad aspect, the invention provides a method of receiving instructions for an implement, for example, a drill string stabilizer, mounted on a drill string, which instructions are transmitted by varying the rate of flow of, or pressure exerted by, the fluid in the bore of the drill string in accordance with one of a plurality of predetermined sequences; the method comprising the steps of: a...

A power unit for a vehicle has an engine (10) coupled to a multi ratio gear box (13). The fuel supply to the engine is controlled by a fuel control system (11) and the selected ratio of the gear box is determined by a ratio selection control system (15A). The unit includes maps (19) in which is stored pre-recorded data relative to engine fuel consumption and exhaust emissions. For a given vehicle ...

Disclosed herein is a diamond synthesizing method comprising the steps of introducing a mixed gas of hydrocarbon gas and hydrogen gas into a reaction vessel (9) which is maintained under a pressure of 1 to 100 Torr and causing dc discharge across a cathode (1) and an anode (2), thereby depositing diamond on a substrate (3) which is placed on the cathode (2). A positive column of H alpha > CH is p...

A method of treating solid waste in soil or solid disposed waste containing unacceptable levels of leachable metals, such as lead, cadmium, arsenic, zinc, copper and chromium, includes mixing the solid waste or soil in place with a phosphate source or a carbonate source or ferrous sulfate. After the solid waste and the additive are mixed, if needed an additional pH controlling agent is mixed into ...

A composition is provided comprising an epoxy resin, a nitroparaffin and a sulfonic acid. The presence of the sulfonic acid retards gellation of nitroparaffin-containing epoxy compositions intended for use in water-dispersible coating formulations cured with modified polyamine resins.

A film with properties such as good thermal stability, enhanced extrudability, improved oxygen barrier properties, and reduced stickiness to metal surfaces is made by the use of a vinylidene chloride composition with small amounts of a plasticizer (such as epoxidized oil or epoxidized alpha olefin), and acrylate/styrene polymer (such as methyl methacrylate/butyl acrylate/styrene polymer) or poly(a...

Free-flowing granules of thermoplastic elastomers are obtained by applying a finely divided mineral powder, namely a silicate from the group comprising wollastonite, kaolinite or mica, in an amount of from 0.005 to 0.5%, based on the amount of elastomer, to the surface of the granules.
