Appl. No.:

10/643260

International Classification:

A63B057/00
A63B069/36

US Classification:

434/252000, 434/347000, 473/221000

Abstract:

The present invention concerns a club for impacting an object. The club may have a club head having a club face. At least one microprocessor in communication with a plurality of infrared sources is also provided. There are also a plurality of infrared sensors, and indicators configurable in a configuration indicating proper club face alignment and a configuration indicating club face misalignment. The infrared sources are periodically pulsed by a microprocessor between an activated and deactivated state. The sensors are configured on the club head to receive infrared from the infrared sources and to generate a signal in response to the infrared received. The device may be used outside, even in the presence of sunlight. By filtering direct current, the false readings caused by sunlight may be reduced. Pulsing the infrared sources, e.g., at 2-6 kilohertz, also helps reduce the detrimental effects sunlight has on the operation of the device. The microprocessor is programmed to receive signals from the sensors when the infrared sources are activated. The microprocessor is programmed to activate the indicators in an aligned or misaligned configuration.

International Classification:

A61B 500

US Classification:

128736

Abstract:

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. A processor (30) is connected to the sensors for processing the output signals to determine a body temperature of the patient utilizing a calibration mapping of a plurality of target temperatures to corresponding output signals taken over a predetermined range of ambient temperatures. A display (34) is driven by the processor for providing a user with a visual indication of the determined body temperature.

International Classification:

G01K 100

US Classification:

374208

Abstract:

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.

International Classification:

G01K 700

US Classification:

702131

Abstract:

The present invention is directed to an electronic device for sensing and indicating the presence of electromagnetic interference in the vicinity of a electronic thermometer and preventing the display of a core body temperature reading when the electromagnetic interference exceeds a predetermined threshold. Disclosed is a tympanic thermometer comprising circuitry and a microprocessor that takes a a plurality of voltage readings from the null input of an operational amplifier in the circuitry. After taking into account ambient temperature conditions into the temperature calculations, the microprocessor compares the average value of the voltage readings taken from the null input against a predetermined threshold in the memory of the microprocessor. If the value exceeds the predetermined threshold, then the microprocessor prevents the display of the core body temperature and directs a display to write an error message. However, if the value does not exceed the predetermined threshold, the microprocessor directs the displays the core body temperature taken by the tympanic thermometer.
