摘要： A fluid properties measurement apparatus for use with a conventional high temperature high pressure test cell includes a load cell assembly and a drive motor that drives a rotating shaft magnetically connected to a vane assembly having multiple vane elements, wherein the motor rotates in response to reactive forces of a fluid sample and the load cell assembly measures reactive forces of the sample. In one embodiment, a stepper motor allows for precise shaft rotation.A method of measuring fluid properties includes frequent measurements throughout a complete rotation cycle of a vane assembly within a test cell. A system interference profile is generated which identifies stress variations resulting from various system components throughout the cycle. Measurements of a sample's fluid properties are likewise performed to obtain a profile. Comparison of the sample profile with the interference profile provides fluid properties measurement independent of stress variations resulting from various system components.

摘要： A medical grade cleansing and numbing agent combination pad is disclosed. An example combination pad includes a pad impregnated with a cleansing agent and a numbing agent each in separate layers. Both the cleansing agent and the numbing agent are released through a same side of the pad without a user having to turn the pad over to apply both the cleansing agent and the numbing agent to a treatment area at substantially the same time. A barrier prevents the numbing agent from contacting the user during application to the treatment area.

摘要： A multi-functional endoscopic system, for use in electrosurgical applications, that includes an imaging endoscope that may be used in combination with various electrosurgical devices, all of which are sufficiently inexpensive to manufacture, such that the endoscope and electrosurgical devices are considered single use, disposable items. The multi-functional endoscopic system of the present invention is suitable for use with a variety of common electrosurgical devices that require electrical/electronic support in order to function. The electrical/electronic support for these electrosurgical devices (e.g., an electrosurgical generator and associated controls) is integrated with the operator console of the imaging endoscope of the multi-functional endoscopic system of the present invention, rather than provided as a separate device. In another embodiment of the invention, an imaging endoscope is provided that integrates or combines the functions of both an imaging endoscope and an electrosurgical device, which can be controlled by a single handheld controller.

摘要： An electrosurgical system comprising, among other things, a control console to which detachably connects one or more electrosurgical probes capable of coagulating and ablating tissue. The control console generates a selectively variable power signal having a duty cycle that is dynamically modulated so as to maintain an average power level of a probe that is lower than a predefined maximum power level. The system can also incorporate both an impedance monitoring system and a current monitoring system as means to detect potentially dangerous situations, as well as a monitoring system for detecting impedance at relatively low power levels upon first activation of the probe. The probe can also incorporate non-volatile memory for storing probe-specific operating parameter data, probe usage data, data restricting probe use, error codes, and control console updates.

摘要： A transducer is optimally driven at or near its resonant frequency by a driver system that adapts to variations and/or changes to the resonant frequency of the transducer due to variations in piezo materials, manufacturing, assembly, component tolerances, and/or operational conditions. The system may include an output controller, a phase track controller, a frequency generator, a drive, circuitry to determine a phase angle between the transducer voltage and transducer current, and circuitry to obtain transducer admittance from the transducer voltage and transducer current.

摘要： Systems and methods for reducing temperature dissipation during burn-in testing are described. A plurality of devices under test are each subject to a body bias voltage. The body bias voltage reduces leakage current associated with the devices under test. Accordingly, heat dissipation is reduced during burn-in.
