Abstract: A method for communicating data from one or more remote computerized coin telephone auditing devices to a central computer via a telephone line, which comprises the steps of receiving input data signals at a remote computerized auditing device, decoding the input data signals into digital data, and processing and storing the data signals. The digital data are then retrieved. The processing, storing and retrieving steps are accomplished by reading and writing the digital data from volatile memory to a non-volatile memory, and from non-volatile memory to volatile memory. The digital data is coded into corresponding output data signals, and are transmitted to the central computer via the telephone line. The receiving and transmitting steps are accomplished by the exchange of a predetermined sequence of data signals, whereby the remote computerized device and the central computer correctly identify each data signal.

Abstract: A portable, automatic external defibrillator, comprising a plurality of capacitors; a capacitor charging circuit; connections from the capacitors to a patient body; and a plurality of semiconductor switches arranged to connect the capacitors to the charging circuit and to the patient body.
Abstract: The invention provides a sealed package system for housing at least one medical electrode apparatus and for enabling the periodic testing thereof, comprising a thin, generally flat flexible envelope constructed and arranged to form an interior cavity for enclosing a conductive gel contact surface of an electrode apparatus, the envelope having at least one continuous layer of a homogeneous, non-conductive, polymeric material, the envelope further having first and second sides; and a structure for conducting current across the envelope to the interior cavity, the conductive structure being electrically connectible to the electrode conductive contact surface.
Abstract: A telecommunications adapter for use with a 110-type patch cord, comprising: a printed circuit board; at least two contact blades for making electrical contact with the 110-type patch cord, the blades having a predetermined configuration and being mounted to the primed circuit board; an electrical connection cable connected to the printed circuit board; and a housing structure having an interior cavity enclosing a predetermined portion of the printed circuit board, the housing structure having a connection end for contact with the 110-type patch cord, the connection end having a stabilizing end for the contact blades and a pair of clamps to engage the 110-type patch cord.
Abstract: A device for sealing an opening or puncture in the wall of a blood vessel or other percutaneous openings. The device includes a shaft section of a small diameter, with an expandable balloon and atraumatic tip at its distal end. The proximal end of the device has an inflation/deflation port which is utilized to inflate the balloon once it is in place within the blood vessel or other body cavity. The entire device is typically placed through a vascular sheath, which is used during invasive percutaneous vascular procedures. The balloon is inflated and withdrawn until it engages the inner surface of the blood vessel or body cavity. The sheath is withdrawn from within the blood vessel or other body cavity to the outside of the body. A fixation collar loaded onto the shaft of the device allows for securement in place, within the blood vessel or other body cavity.
Abstract: A package transport mechanism having a plurality of phase adjustable lug-type flights. The mechanism is incorporated in a continuous motion packaging assembly for loading article groups into cartons or other carriers which comprises an article infeed mechanism supplying at least one stream of articles; an article group selection and transport mechanism intersecting the article infeed mechanism to form and transport a longitudinal stream of article groups of a predetermined pattern; a package supply mechanism synchronized and moving parallel with the article group selecting mechanism to provide packages with open ends facing the moving article groups; and an article group transfer mechanism which is constructed and arranged to move the article groups into the open ends of the packages.
