Abstract: A catheter pulse device is disclosed which is activated by vacuum signals and which is used adjacent to or directly attached to a catheter 26 for withdrawing fluids from a patient's body cavity, such as the stomach. The device operates immediately following the normal cessation of suction in an intermittent suction system and returns a minute quantity of the withdraw fluid back into the catheter itself to clear the withdrawal passageways. The pulse device provides protection against an excess of vacuum from reaching the patients cavity by utilizing a specially designed valve that opens and closes the path between a source of regulated vacuum and the patient. That valve is balanced such that it initially opens at or approximately at the point the vacuum on the patient side of the valve reaches the regulated vacuum set by the doctor or other knowledgeable personnel, and thus the vacuum to the patient does not exceed a set amount. The pulse device 22 can therefore be used in a system where the device itself is located directly on or adjacent the catheter 26 itself, thus eliminating long distensible passageways between the pulse device and the patient and thereby minimizing the detrimental reservoir effect of such long passageways.

Abstract: Linearity and efficiency of a radio frequency two-stage power amplification device (10) are increased by employing two tuned circuits 16 and 18 in a driver stage (12) and two tuned circuits (22 and 24) in a high power stage (14). After selecting elements of tuned circuits (22 and 24) in order to optimize the high power stage (14) for efficiency, linearity and power output, elements are selected for tuned circuits (16 and 18) in order to cause the intermodulation output components associated with the driver stage (12) to have a 180° phase angle relative to the intermodulation output com­ponents associated with the individual high power stage (14). This phase angle relationship will cause the intermodulation output component products from the driver and high power stages (12, 14) to cancel.

IPC: H02H6/00

Abstract: A circuit breaker with over-temperature protector and low error I²t calculator is provided. The over-­temperature protector includes a fixed current source (Q016, Q111, Q112, Q113, Q114) which exists within the control circuit of the circuit breaker (10) to provide current to resistive elements (R100, R018) to produce a voltage thereacross which increases with a positive temper­ature coefficient as the surrounding temperature increases. The resistor is connected to the base-to-emitter circuit of a transistor (Q123). The base-to-emitter circuit has a minimum firing voltage which decreases with an increase in ambient temperature. The value of the resistive element, the amount of current provided by the fixed current source and the transistor base-to-emitter minimum firing voltage are chosen to cause a firing circuit (Q833) for the opening apparatus (FST) of the circuit breaker to be actuated when a predetermined ambient temperature which may be 90°C, for example, is obtained. There is also provided an active memory device (Q766) which is utilized to discharge a capacitor (C2) with a time constant which approximates the heat dissipating time constant associated with a conductor (L1, L2, L3) to be protected by the circuit breaker in question. The capacitive element is charged initially by a small charging current (iLDT) which is related to the square of the current flowing through the conductor to be   protected. Thus, the voltage developed across the capaci­tor is related to the amount of heat built up in the conductor to be protected and when this voltage reaches a predetermined level, the circuit breaker mechanism is actuated to cause the circuit breaker contacts (K1, K2, K3) to open to thus prevent further heat accumulation in the conductor to be protected. However, if the current which is causing conductor heat accumulation ceases or decreases, the need for opening the circuit breaker decreases accord­ingly. In order to account for the heat dissipation associated with the previous situation, the active memory element is utilized to discharge the capacitor as men­tioned. However, during the charging operation, the presence of the active memory element would provide a parallel path for the charging current for the capacitor this would introduce an error into the voltage across the capacitor. Therefore, the active element is disconnected from the circuit by an appropriate sensing current (R763, R4104, R762, Q764, Q784) so that during a charging opera­tion for the capacitor none of the charging current is lost through the memory device.

Abstract: A method of performing an integral transform operation (such as a Fast Fourier Transform), wherein the underlying algorithm is partitioned to provide an efficient sequence of data operations. Preferably the address calculations are performed separately from the data calculations, and the algorithm is partitioned so that the microcode sequence for all but the last few data calculations is constant. Thus, the bandwidth at the interface to the numeric processor is conserved, and control storage in the numeric processor is also efficiently conserved. Moreover, the preferred partition for performing Fast Fourier Transform manipulates data in reasonably large subsets (e.g. 8 floating-point words at a time). This turns out to use less data bandwidth than would be required using smaller data subsets.
