Abstract: A defibrillator (112) is designed for implantation in a patient and for program-ming certain of its parameters after im-plantation, including energy content of a shock waveform and timing of delivery of the shock waveform. A shock waveform generator (59) of the device is responsive to a trigger signal for timed production of a shock waveform having a programmable shape and energy content designed for ter-minating atrial or ventricular fibrillation (AF or VF) of the patient. A detection circuit (50, 55, 56) processes a sensed car-diac signal of the patient to determine the relative timing of various portions of the cardiac signal, including the P-wave and the T-wave. In a test mode of the device, the energy content of a shock waveform is programmed to a magnitude exceeding the upper limit of vulnerability (ULV) of the patient, and the trigger signal times the delivery of a shock waveform of proper magnitude relative to the occurrence of a selected event in the cardiac signal, such as a cardiac stimulus, the P-wave or QRS complex, for application to the patient's heart coincident with the vulnerable period of a P-wave or a T-wave. The probable ULV of the patient's heart is determined or estimated, the defibrillator is set to deliver a shock of sufficient energy to exceed the probable ULV, and delivery of the shock is initiated into the vulnerable period of the P-wave or T-wave. The defibrillator (12) is selected with the capacity to deliver a shock of maximum energy exceeding the probable ULV by a margin deemed to provide an adequate safety margin for the patient.  The occurrence of the vulnerable period of the P-wave or T-wave is precisely timed from a predetermined event in the patient's cardiac signal.

Abstract: Altimètre radar Doppler à compensation de retard, qui élimine la courbe de retard relatif associée à l'énergie réfléchie par un diffuseur (x3, x2, xn) situé dans la direction longitudinale d'une plate-forme aérienne (10), pour lequel on désire une estimation plus précise de l'altitude. Par décalage Doppler de chaque écho, la portée indiquée pour chaque diffuseur sur son historique d'illumination est égale à la portée minimale xh obtenue quand la vitesse relative entre le radar aérien (10) et le sol est réellement nulle. La compensation de chaque signal, de façon que la totalité de son historique longitudinal puisse être utilisée pour l'estimation de son altitude, amène un avantage de plus de 10 dB dans l'amélioration du gain par rapport aux systèmes existants et provoque moins de dégradation depuis la topographie de surface (13).

Abstract: An electro-optical detection system for detecting objects within the boundaries of a monitored zone, comprises a plurality of LED emitter and photodetector pairs. Each emitter (12) emits a beam of pulses of light energy into the monitored zone, and its paired photodetector (14) detects light energy including light energy from the beam that is reflected from an object within the monitored zone and generates light detection signals. A controller (10) operates the emitter and photodetector pairs and evaluates the light detection signals to discriminate between light energy of beams reflected from an object within the monitored zone and other light energy. The controller can selectively adjust the evaluation of the light detection signals to adjust the effective boundaries of the monitored zone.

Abstract: In electronic devices containing microprocessors, including data processing systems, logic is loaded to storage registers within a microprocessor or other suitable non-volatile storage medium during the manufacturing process. The logic provides for detecting the presence of a battery employed to power an interval timer. Also, the logic provides pre-set time intervals that operate in conjunction with the interval timer and existing or installed device state sensing devices. One time interval provides a warning to a user that the protected device will be deactivated within a specified period of time if a preset authorization code is not entered into the device.  Another interval is provided to carry out deactivation if the preset code is not entered. Types of automatic deactivation include: partial deactivation, which comprises allowing communication via modem with a service center to obtain authorization; fully deactivated state requiring entry of a key code to reactivate the device and destructive deactivation which destroys circuits within the device necessary to operation.
