Appl. No.:

10/459267

Inventors:

Robert Mathews - San Diego CA, US

International Classification:

A61B005/04

US Classification:

600/372000

Abstract:

A system for measuring a biopotential signal produced by a body in free space at a location adjacent to the body, and if desired, through clothing, includes a probe that can be positioned adjacent to the body. The probe includes a conductive electrode to receive the biopotential signal and a conductor that is maintained at a fixed distance from the electrode. The potential of the conductor can be maintained substantially equal to the potential of the electrode to shield the electrode from stray electrical noise. The system further includes a high impedance first stage amplifier that is incorporated into the probe and electrically connected to the electrode using a relatively short connector to minimize connector noise. Functionally, the first stage amplifier compares the electrical potential of the electrode to a second potential (e.g. a local ground) and generates a signal that is indicative of the biopotential.

Abstract:

A self-service beverage dispenser which includes a cabinet, a plurality of dispensing heads mounted in upper portion of the cabinet and a support for bottles to receive the beverages that are dispensed from the dispensing heads. The support for the bottles includes a trough carried by the cabinet beneath the dispensing heads to receive and to carry away beverages spilled into the trough and a perforated positioning platform for a succession of bottles forming a screen cover for the spill trough. A support for a succession of bottles to receive beverage from a dispensing head. Optionally a positioning bracket secured to the cabinet is provided beneath each nozzle for holding a bottle with the filling opening in the neck thereof out of direct alignment of the gravity induced stream of beverage flowing from a dispensing head. Disposable funnels are provided for surrounding a nozzle at its upper, larger end and for entering the filling opening of the bottle supported on said perforated platform at its lower, smaller end, thus providing a flow path for beverage flowing from a dispensing head into the open end of the bottle to be filled.
