Abstract: Un appareil utilisé en association avec une aiguille (32) de transfusion d'un liquide sert à détecter l'infiltration du liquide à travers la paroi vasculaire dans les tissus périvasculaires. L'appareil comprend un dispositif (10) non-invasif à antenne conforme de micro-ondes placé au-dessus de la zone de transfusion du liquide. Un radiomètre à micro-ondes (RD1) est connecté au dispositif à antenne (10) pour détecter la température sous-cutanée à cet endroit. Un dispositif à antenne de référence (R1) est également utilisé afin de permettre d'établir un différentiel de température approprié. Dans un autre mode de réalisation de l'invention, un dispositif commutateur (50) est prévu pour que, dès qu'une situation de danger est détectée, le liquide (54) puisse être immédiatement coupé et un agent neutraliseur (58) introduit dans l'aiguille (32).

Abstract: The present invention provides a method and system for transmitting a multi- frequency signal composed of discrete tones of constant envelope parts that are amplified by a bank of fully saturated tamplifiers operating in their most power efficient mode. After amplification and transmission, the signals are multiplexed in the air as opposed to multiplexing before amplification that allows for more efficient amplification as well. In a preferred embodiment, the system has two or more transmitting antennas, and the method comprises: (a) generating a first signal of a first carrier frequency and a second signal of a second carrier frequency; (b) transmitting the first signal of a first carrier frequency on a first antenna and the first signal of a second carrier signal on a second antenna for a predetermined time period; and (c) transmitting a second signal of the second carrier frequency on said first antenna and a second signal of the first carrier frequency on the second antenna for the predetermined time period. Preferably, the signals are transmitted using an amplifier that is essentially fully saturated.

Abstract: A process (100) of determining target parameters of an object within a field of detection of an automotive radar system, comprises the steps of (a) establishing a target range from a sequence of ranges (101); (b) dwelling on the target range for an initial dwell time to obtain sensor data (102); (c) determining if the sensor data corresponds to the presence of an object or to the absence of an object (103) at the target range based on probability density distributions of an object being present and being absent at the target range, and if such determination cannot be made, then repeating steps (b) - (c) until the determination can be made; (d) if the sensor data is determined to correspond to the presence of an object in step (c), then dwelling at the target range for an extended dwell time to obtain additional sensor data for determining the target parameters (104) of the object before proceeding to step (e); and (e) establishing the next of the sequence of ranges (105) as the target range before reiterating steps (b)-(e).
