摘要： A system for selectively collecting location information in a tracking environment includes a first energy signal identification badge for detecting trigger signals and transmitting identification data signals indicating existence of a proximity condition between the first badge and a source of the trigger signals. The trigger source transmits trigger signals of a predetermined power level, wherein the first badge can detect the trigger signals only if the first badge is within a predetermined radius of the trigger source when the trigger source transmits the trigger signals. The first badge transmits the identification data signals when the first badge detects the trigger signals transmitted by the trigger source.

摘要： A configurable system for obtaining a measurement of activity producing biopotentials in a subject, for example EEG or EMG biopotentials. The system includes a three electrode array positionable on the head of the patient to detect signals generated in the head of the subject. The array is connected to a monitor that includes a switch arrangement that is selectively configurable to direct the incoming signals received by the electrode array to specified inputs of a differential amplifier that creates signals that are displayed on the monitor. The switch arrangement is configurable to measure the activity of the subject in a conventional 1-channel measurement mode. The switch arrangement can also be configured to simulate a 2-channel measurement mode by alternating the configuration of the switch arrangement in a pre-determined manner.

摘要： A method and apparatus for performing single-point projection imaging uses an X-ray source and a line scan camera present at a set distance therefrom and provided with a digital detector. The X-ray source, as well as the line scan camera, are adapted to rotate around an object placed between the X-ray source and the line scan camera. The X-ray source’s focal spot is aligned at a desired position and the object is then imaged by scanning it with a beam emanating from the X-ray source, which beam is received by the detector of the line scan camera. The scanning motion is effected in such a way that the focal spot remains essentially stationary during the imaging process.

摘要： An open ventilation system for intensified breathing that includes both a manual ventilation system and an automatic ventilation system. A ventilation selection switch is positioned in the system prior to the patient circuit to select between the manual and automatic ventilation systems. The manual ventilation system includes a manual bag filling valve that controls the flow of inhalation gases from the ventilation selection switch to a manual bag. The manual bag filling valve includes a valve assembly that is movable between an open position and a closed position based on the difference in the forces created by the pressures of the manual bag and the inhalation gas.

摘要： A paramagnetic oxygen sensor and method employs a pressure sensor having a membrane extending through an air gap for a magnetic field. A piezoelectric element is mounted on the membrane. Gas chambers are formed on either side of the membrane. The gas mixture, the properties of which are to be measured, is supplied to one of the chambers. A reference gas is applied to the other chamber. A pulsating magnetic field is provided across the air gap and through the chambers containing the gas mixture and reference gas. The differing responses of the gas mixture and reference gas to the magnetic field deflect the membrane. The deflection of the membrane is sensed by the piezoelectric element. The piezoelectric element maybe operated either in a passive mode or active mode to sense the deflection of the membrane.

摘要： A closed loop method and apparatus for controlling the administration of an hypnotic drug to a patient. Electroencephalographic (EEG) signal data is obtained from the patient. At least one measure of the complexity of the EEG signal data is derived from the data. The complexity measure may comprise the entropy of the EEG signal data. The EEG signal data complexity measure is used as the feedback signal in a control loop for an anesthetic delivery unit to control hypnotic drug administration to the patient in a manner that provides the desired hypnotic level in the patient. An EEG signal complexity measure obtained from the cerebral activity of the patient can be advantageously used in conjunction with a measure of patient electromyographic (EMG) activity to improve the response time of hypnotic level determination and of the feedback control of drug administration. A pharmacological transfer function may be used, along with pharmacokinetic and pharmacodynamic models.

摘要： The invention concerns a method and an apparatus for monitoring a condition of a patient under anesthesia or sedation. For this purpose there is a sensor for acquiring a signal that represents peripheral cardiovascular flow in the patient. Successive heart beat pulses are detected and predetermined pulse wave parameters are measured repeatedly in said signal, and predefined pulse wave parameters within said heart beat pulses are measured, too. At first, said predetermined pulse wave parameters in a number of successive heart beat pulses are compared in respect to possible occurence of a substantial alteration. At second, if the alteration is noticed, a statistical reference value is calculated by deriving values from at least said predefined pulse wave parameters, and the change(s) between at least one predefined pulse wave parameter and said reference value is quantified. The results and/or intermediate results are finally displayed and/or recorded.
