Patent number: 6238089Abstract: A probe tip in combination with a seal assembly that prevents debris and other contaminants from entering the probe tip. In the preferred embodiment, the seal comprises a tube with a filter holder assembly attached at the distal end of the holder. The filter holder assembly includes an infrared filter seated inside a screw-on member that is attached to a holder member with a sealing member located directly behind the infrared filter. During manufacturing, a predetermined force is applied to the proximal end of the tube which drives the distal end of the tube and filter holder assembly against the probe tip opening, thereby forming a watertight seal thereto. In alternative embodiments, the seal assembly may be comprised of a collar and gasket combination instead of a filter holder assembly.Type: GrantFiled: August 25, 1998Date of Patent: May 29, 2001Assignee: Sherwood Services AGInventors: John Vodzak, John J. Korff, Gary J. O'Hara, Frederick F. Schweitzer, Jr., Mark A. Davis

Patent number: 5980451Abstract: A sanitary protective cover or sheath for the ear canal probe of a tympanic thermometer. The speculum has a generally tubular body portion and an infrared transparent membrane attached to and sealing the forward end of the body portion. While the tubular body portion is being injection molded of plastic material such a polypropylene or polyethylene, a film of a similar plastic material is mated to the forward end of the membrane and is thus severed from the film and one side thereof thermally bonded to the tubular body portion. At the same time a bonding ring of roughly the same diameter as the forward end of the tubular body portion is injection molded. The ring is thermally bonded to the opposite side of the film in alignment with the forward end of the tubular body portion.Type: GrantFiled: January 12, 1998Date of Patent: November 9, 1999Assignee: Sherwood Services AGInventors: Gary J. O'Hara, David B. Phillips, Kishan G. Hingorani

Patent number: 5293877Abstract: A body temperature thermometer has a probe head assembly (8) which includes a first sensor (10), such as a thermopile, for generating a first output signal representative of an amount of infrared radiation impinging thereon The probe head assembly further includes a waveguide (16) and a surrounding hollow probe (14) for receiving infrared radiation emitted by a biological surface tissue, such as the external ear canal and tympanic membrane of a patient, and directing the radiation to the first sensor. A second sensor (12) is mounted in the probe head assembly for generating a second output signal representative of a temperature of the first sensor. A third sensor (26) is thermally coupled to the waveguide for providing a third output signal representative to the temperature thereof.Type: GrantFiled: March 11, 1992Date of Patent: March 15, 1994Assignee: Sherwood IMS, Inc.Inventors: Gary J.

Patent number: 4790324Abstract: A hand held probe unit has an infrared sensitive thermopile mounted in a metal housing kept at a constant reference temperature by a regulator circuit. A waveguide tube, surrounded by a thermally insulative probe, directs infrared emissions to the thermopile. The thermopile and regulator circuit of the probe unit are electrically connected to processing circuitry in a chopper unit. Prior to taking a patient's temperature, the probe unit is mated with the chopper unit so that the thermopile detects infrared emissions from a reference target which is also kept at a constant reference temperature by another regulator circuit. The processing circuitry repeatedly acquires the output level of the thermopile and stores calibration data. The probe unit is then removed from the chopper unit, the probe is covered with an IR transparent, disposable speculum, and is inserted in the patient's external ear canal.Type: GrantFiled: March 25, 1987Date of Patent: December 13, 1988Assignee: Intelligent Medical Systems, Inc.Inventors: Gary J.

Patent number: 4223893Abstract: An electronic backgammon game includes an illuminated display which is energized utilizing a microprocessor programmed according to the rules of the game of backgammon. The display includes pictorial representations of pips of a backgammon board, and first, second, and third sets of electrically responsive visual indicators. The first set of visual indicators manifest a substantially randomly determined chance value, the second set of visual indicators indicates the occupancy of a given pip during the play of the game, and the third set of indicators indicates which contestant is to enter the next in sequence play instruction. The microprocessor energizes the third set of indicators according to a value given by the first set of indicators to indicate which contestant is to enter the first instruction.Type: GrantFiled: November 11, 1975Date of Patent: September 23, 1980Assignee: Tryom, Inc.Inventors: Tim A.
