摘要： A digital circuit both provides multiphasic timing signals and regulates the operating voltage of a non-ideal power source. In one embodiment, a delay line is provided whose delay characteristics vary inversely with operating voltage. Control gates are connected to selected outputs of the delay line to receive at differing times a control signal propagated through the delay line. In a preferred embodiment the control gates generate output signals the duration of which are determined by the delay characteristics of the delay line (and thus by the level of the operating voltage), such that the output signal duration increases in response to increases in operating voltage. The output signals activate current sinks or loads which increase the current drain on the non-ideal power source, thereby depressing its voltage. Regulation is optimized when the power source comprises a power supply having a significant output impedance at normal operating current levels, or the a power source is derived from a remote power supply coupled to said remote power supply by a high impedance or lossy coupling.

摘要： A door retainer for removably mounting on the folding steps of a recreational vehicle to prevent the door from opening, which door retainer is characterized by a flat step plate designed to fit on the top step of the folding steps and provided with a downwardly-extending rear plate for engaging the rear edge of the top step. A post is upward-standing from the step plate in close proximity to the door, in order to prevent the door from opening when the step plate and the rear plate are installed on the steps in functional position. A latch bracket projects downwardly from fixed attachment to the step plate and a tab slot is provided in the rear plate opposite the latch bracket for receiving a tab located on one end of a keeper plate. The opposite end of the keeper plate is fitted with a keeper bracket for engaging the latch bracket on the step plate and receiving the hasp of a padlock to secure the step plate and the rear plate in functional configuration on the folding steps of the recreational vehicle.

摘要： An apparatus and method for controlling the operating temperatures and differential temperature of a curie effect temperature sensing switch is disclosed. The temperature switch is adapted to provide temperature control of a cold plate in a reagent refrigerator. The temperature switch activates cold plate cooling devices when the cold plate temperature is above a first operating temperature and deactivates the cold plate cooling devices when the cold plate temperature is below a second operating temperature. An electromagnet is fixed external of and relative to the temperature switch so that the strength of the external magnetic field sets the operating temperatures of the temperature switch. A potentiometer is used to incrementally vary the current supplied to the electromagnet to thereby incrementally adjust the strength of the external magnetic field and the operating temperatures. A microprocessor may be provided to adjust the voltage supply of the potentiometer, which allows remote control of the operating temperatures. A second potentiometer is connected to the electromagnet so that it incrementally adjusts the current passed to the electromagnet as a function of whether the temperature switch is open or closed. Incremental adjustment of the second potentiometer provides incremental adjustment of the temperature differential. A monitor provides a warning signal if the temperature switch does not open and close within a predetermined time interval.

摘要： The present invention provides means and methods for noninvasively identifying the blood pressure characteristics in each of the seven types of vessels in the circulatory system, including the central venous pressure (CVP) through a single monitoring system using fluid depletion plethysmography. Known pressure is applied to a body region in increasing amounts to force blood volume from the body region in step-wise fashion through each vessel type. Blood volume depletion for each vessel type is measured by the increasing electrical impedance of the body part during depletion and is plotted against the increasing pressure data. The resulting series of slope changes within the plotted curve reveals the blood pressure for each vessel type. The data obtained may further be used to determine vessel wall compliance/tension as well as standard measurements such as pulse and large artery systolic and diastolic pressure. Release of the applied pressure may then yield similar data by measuring blood volume replenishment against the decreasingly applied pressure during the same diagnostic operation. The method is not dependent on oscillometric or pulsatile measurement methods. The electrical leads of the impedance/volume sensor and the means for applying pressure to the body part are coextensive to ensure accurate indication of blood volume depletion and replenishment in the body region under pressure and may be incorporated into a single integrated structure.

摘要： A patient monitoring system which includes a portable device and a central station. The portable device includes an ECG and a photo-plethysmograph connected to the patient; arrhythmia analysis apparatus; an expert system for determining if a pre-established critical parameter set has been exceeded; and a wireless wide area communication device for automatically contacting the central station via a public cellular phone network when the critical parameter set has been exceeded. When the central station is contacted, the patient's ECG waveforms, measurements, and trends, are sent to the central monitoring station and a two way voice channel between the patient and the central station is automatically opened. The central station includes a computerized facility which has a station from which a clinician can observe the real time data being sent from the patient, the patients historical records and from which the clinician can talk to the patient and activate therapeutic devices attached to the patient such as an external defibrillator, a pacer or an automatic drug infusion device.
