摘要: A self-balancing apparatus for a centrifuge is disclosed which employs two arcuately movable counterweights. The centrifuge has a plurality of receptacles for receiving one or more assay cartridges. Control apparatus in the centrifuge determines the location and number of received cartridges. Desired counterweight positions are then calculated which will substantially balance the centrifuge. The counterweights are moved into these positions prior to the centrifuge being operated at high speeds.

摘要: A system for tracing uterine contraction is disclosed. The system comprises a probe and an electronics module. The electronics module includes a drive circuit and an output section having a frequency counter. The output section also includes a strip-chart recorder driven by a frequency-to-voltage converter. The probe includes an electro-mehanical transducer which is driven at resonance by the action of the drive circuit. When the probe contacts the abdomen of a pregnant subject, changes in the mechanical impedance of bodily tissue during a contraction affect the resonant frequency of the probe and thus the frequency output by the drive circuit. This frequency can be read directly from the frequency counter and recorded on the strip-chart so that contractions can be traced.

摘要: An ultrasound system, employable for medical imaging, includes an electronics module and a probe. The probe includes a body, a transducer, a driver, a window and coupling fluid. The electronics module includes a transmitter which generates transmission pulses which are converted by the transducer to ultrasound pulses and a receiver which analyzes electrical signals resulting from the conversion of ultrasonic reflections received by the transducer. The electronics module controls delays in the transmission and reception between individual elements of the annular phased array transducer to control focussing. The driver provides for mechanical steering of the transducer. The coupling fluid provides for ultrasonic coupling between the transducer and the window and the subject while permitting the steering movement of the transducer. The coupling fluid is a mixture of 1-Butanol in Glycerol. The attenuation of that mixture can be adjusted without impairing velocity matching by adding suitable amounts of 2-Hydroxyethyl ether.

摘要: A data card drawer for installing a data card, such as a compact flash card, into a device that uses data cards. Devices that use data cards include, for example, medical devices, and more particularly defibrillators. The data card drawer electrically isolates the data card from the user when the user is installing or removing the data card from the device. The data card drawer may also be formed to provide a closure to the opening in the device housing provided to receive the data card. Further, the data card drawer may be formed to prevent damaging pins located on a pin connector within the receiving device which communicate data with the data card. The data card drawer preferably mates with the device to prevent ingress and egress of foreign matter and moisture.
