The ambient temperature used in the function is assumed at about 80° F. but modified with detector temperature weighted by 20%.

Abstract: An infrared radiation ear thermometer has an optical system, an infrared detector, an ambient temperature sensor, and display unit, a signal processing section. Wherein, the infrared detector further includes an infrared sensor and a temperature reference sensor; the infrared sensor is deposition on the substrate and the temperature reference sensor is mount near the substrate of the infrared detector to convert the infrared signal into an electrical signal and sense the reference temperature separately. The ambient temperature sensor is set in the space near the optical system to detect the fast change of the ambient temperature. The signal processing section receives the signals from these temperature sensors to produce an offset by a mathematical algorithm. The offset is used to correct the temperature reading and maintain a high precision even though the ear thermometer suffers from an extreme temperature change.

Abstract: A computer-based method of determining a thermal exposure of a product disposed within a shipping container to determine whether a conditioned environment is required for shipping. A shipping route is defined from a first geographic location to a second geographic location. The thermal characteristics of the shipping container are provided, as is a historical weather database. Ambient temperatures, cloud cover and humidity from the historical weather database are retrieved which correspond to the shipping route. A system of mathematical equations are generated to correspond the retrieved ambient temperature to an ambient temperature within the shipping container and to the product temperature. The corresponding product temperature is compared to a thermal exposure profile for the product to determine if the corresponding product temperature is within the thermal exposure profile.

The detector generates a signal corresponding to a detected temperature. A microprocessor receives the signal and processes it in accordance with a programmed characteristic. The processed signal is delivered to an output switch which produces a control signal for controlling the delivery of roll material to a roller of the rolling mill.

Abstract: A game player is allowed to punch a punching ball and the shape of a captured image is transformed in conformity with the punching force applied to the ball. An image is captured by a camera or memory card reader. The player punches the punching ball, causing the shape of the captured image to be transformed. The larger the acceleration of the punching ball when it is punched, the greater the transformation in the shape of the captured image. The transformed image is displayed on a display unit and may be printed if desired. The player can experience a game more realistic than one in which the shape of a computer-graphics image is transformed.

Abstract: An improved prediction-type medical thermometer that provides an accurate estimate of a patient's temperature in substantially reduced time as compared to prior thermometers of this kind. This improved performance is achieved by using a special hollow probe tip having a low heat capacity and incorporating a resistive heater that is actuated only upon removal of the probe from a base housing. In particular, a processor measures an initial temperature upon the probe's removal and applies to the heater an initial electrical signal having prescribed parameter, e.g., pulse duration, that varies according to the initial temperature measurement. This warms the probe to a prescribed temperature at or near about 93.degree. F., after which the processor applies a sequence of pulses to the heater, to controllably regulate the probe's temperature to the prescribed value.

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.
