Abstract:
A sterilization system consisting of a mobile emitter, a sensing subsystem and a data logging subsystem is described. The emitter has one or more UV emitting lamps or devices. The sensing system comprises at least one remote UV sensor and at least one door sensor. The door sensor comprises a safety shut off door detector and may contain an emergency stop detector and arming detector to protect people from being exposed to UV energy. The system has a remote control for starting, stopping and setting system parameters which include but are not limited to: treatment time, dosage, room size, room number, unit number, floor, facility name, operator name, operator identification number, password, default dosage values, dosage, and patient identification number. The number of treatments per unit of time can be maximized because of the use of incident light measurement.

PROBLEM TO BE SOLVED: To accurately calculate an illuminance.SOLUTION: An imaging device comprises: an exposure control section for controlling plural exposure periods; a determination section for determining whether saturation has occurred, using at least one of plural pieces of data obtained in the exposure periods; and an illuminance calculation section which, if the determination section determines that the saturation has occurred, calculates the illuminance using a piece of data different from the piece of data used for the determination. If the average of the pieces of data is for example a threshold or more, the determination section determines that the saturation has occurred. This technique is applicable to an imaging device such as a CMOS.

Abstract:
A spectrophotometer apparatus (200) is adapted to provide spectral reflectance measurements of object samples. The apparatus (200) comprises a source light (254) and a reflection optics assembly (264, 268). Signals representative of reflected light are analyzed and data provided to an operator representative of the spectral response characteristics of the object sample (252). The apparatus (200) further comprises a side sensor (276) having a fixed spectral response characteristic for compensating the reflectance measurements in accordance with the light intensity emanating from the lamp. For purposes of calibration, a series of time-sequenced measurements are made of a reference sample. Utilizing these measurements, the apparatus (200) provides computations of compensation coefficients for each spectral segment. The compensation coefficients are utilized, with the side sensor measurements, to provide normalization of the reflectance measurements for each segment and for each measurement within the timed sequence. For each segment, a scale factor is then determined. The scale factors, compensation coefficients and side sensor measurements are employed to compensate actual reflectance measurements, with further compensation provided by a determination of temperature coefficients.

L'instrument utilise un microprocesseur (56) et un affichage digital (39) pour calculer et indiquer les differentes fonctions de temperature. Une compensation est prevue pour les effets des changements du pouvoir d'emission et de la temperature ambiante qui, autrement, entraineraient des lectures inexactes.

Abstract:
Un thérmomètre médical à infrarouge autonome possède une sonde allongée (15) pouvant effectuer un mouvement réciproque entre une position rétractée entièrement à l'intérieur de l'enceinte (11) du thermomètre et une position étendue à l'extérieur de l'enceinte. Lorsqu'elle est sortie, la sonde (15) est adaptée pour être introduite dans le canal auditif de l'oreil externe d'un patient pour mesurer la température du corps du patient. Lorsque la sonde est rétractée dans l'enceinte (11), une plaque de référence (21) pivote devant la sonde (15) pour faciliter le calibrage. L'avance de la sonde (15) vers sa position déployée de fonctionement fait pivoter automatiquement la plaque de référence (21) en l'éloignant de la sonde (15) qui avance et, de plus, fait avancer automatiquement un couvercle jetable protecteur (43) à partir d'un conteneur (45) contenant un grand nombre de ces couvercles vers une position où il s'étire automatiquement en recouvrant la sonde (15) pour assurer une protection hygiénique.
