Patent number: 6070651Abstract: A thermal heating and cooling fan device for providing warm or cool air from the circulation of warm or cool fluid therethrough. The device includes a housing having a pair of opposite open ends. A first transfer coil is provided in the interior of the housing. Intake and output conduits are fluidly connected to opposite ends of the first transfer coil. The distal ends of the intake and output conduits are fluidly connectable to a fluid source. The distal end of the intake conduit is designed for drawing fluid into the intake conduit and the distal end of the output conduit is designed for discharging fluid from the output conduit. A pump is provided for pumping fluid from the input conduit through the first transfer coil to the output conduit. A fan is provided in the housing for moving air from one open end of the housing through the interior of the housing over the first transfer coil to another open end of the housing.Type: GrantFiled: July 30, 1998Date of Patent: June 6, 2000Inventors: Judith Phillips, David B.

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: 5680898Abstract: A heat pump and air conditioning system is provided with a thermal storage device, a variety of distribution devices for blocking or allowing flow of the system working fluid, and a controller for manipulating the distribution devices to control flow of the working fluid through the thermal storage device to allow thermal energy storage or thermal energy discharged depending upon sensed conditions. In addition, a thermal storage device is provided which is suitable for use in a heat pump and air conditioning system. The thermal storage device includes a container through which refrigerant coils pass. The container is filled with an unencapsulated phase change material having a first melt temperature and an encapsulated phase change material having a second melt temperature higher than the first melt temperature. Further disclosed is a method for conditioning a space by use of heat pump and air conditioning systems incorporating thermal storage.Type: GrantFiled: February 5, 1996Date of Patent: October 28, 1997Assignee: Store Heat and Produce Energy, Inc.Inventors: Alexander P.

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.

While the tubular body portion is being injection molded of a plastic material, a film of a similar plastic material is mated to the forward end of the tubular body portion. A portion of the film defining the membrane is thus severed from the film and thermally bonded to the tubular body portion.Type: GrantFiled: May 8, 1985Date of Patent: May 5, 1987Assignee: Intelligent Medical Systems, Inc.Inventors: Gary J.
