摘要： In one embodiment, an ultrasound imaging assembly (80) includes a housing (82) having a longitudinal axis (88), a proximal end (86), and a distal ending (84) defining a receptacle (90). The imaging assembly includes a transducer package (60) having a central axis (62) and an imaging surface (66) positioned at a desired angle (106) relative to the central axis. The transducer package is at least partially disposed within the receptacle so that the central axis is generally perpendicular to the longitudinal axis. Such a configuration permits a relatively large percentage of the ultrasound signal to pass through a sheath (120) surrounding the imaging assembly and reduces assembly-to-assembly variations.

摘要： A steering column assembly for an automotive vehicle has a bearing which supports the steering shaft and a spring wedge unit for supporting the bearing. The spring wedge unit is in the form of an integral one-piece ring of flexible resilient material, preferably urethane, and encircles the shaft. The ring has an annular wedge and an integral annular spring flange. The wedge has a cylindrical radially inner surface in bearing contact with the shaft, and a conical radially outer surface providing a radially inner support for the bearing. The spring flange is tapered and abuts a tapered portion of the shaft under pressure which resiliently flexes the spring flange and resists axial movement of the ring to dampen vibration and suppress noise.

摘要： A device that provides for the non-invasive data monitoring of analog IO of a Programmable Logic Controller (PLC) system. The output is ultimately displayed on an interface in real-time and is measured directly from the IO channel. This type of device allows the accurate reading and analysis of errors and erroneous data within a device and transmission of said data to disparate secondary devices for use.

摘要： A battery pack system module may include a module bypass switch for allowing charge current to bypass the battery pack system module. The module bypass switch may be activated to divert charging current from the battery pack system module to other battery pack system modules. The charging current may be diverted to bring other battery pack system modules into balance with the battery pack system module. That is, to bring the state of charge of all battery pack system modules into coarse balance. When the module bypass switch is activated, charging current through the module bypass switch may be monitored by a current sensing device such as a current sensing resistor. A microprocessor may receive information about the bypass current level and use the information to determine when to de-activate the module bypass switch. Sensing current through a module bypass switch allows more accurate and quicker inter-module balancing.

摘要： Battery cells may be monitored and a historical profile of the battery generated. The historical profile may be used to analyze a state-of-health of the battery cell. For example, the historical profile may be used to determine when a battery cell has developed an internal short that creates a safety hazard. The historical profile may include a count of the number of times the battery cell was out of balance and a count of the number of Coulombs the battery cell was out of balance. The number of Coulombs may be counted for a window of time. When the number of Coulombs exceeds a Coulomb threshold, a state-of-health flag may be set for the battery cell. The Coulomb threshold may be adjusted based, in part, on the counted number of times the battery cell is out of balance.

摘要： A vascular catheter system comprises a catheter body having a proximal and distal portion and a single common lumen therebetween. The catheter body includes a first connector secured to the distal end of the proximal portion and a second connector secured to the proximal end of the distal portion. The connectors can be selectively connected to each other to join the lumens of the proximal and distal portions together in a continuous, axially fixed relationship. Disposed within the lumens, when the proximal and distal portions are joined together, is a drive cable. The drive cable may be movably, rotatable about its own longitudinal axis and carries at its distal end, a work element, which is typically an ultrasonic imaging transducer or interventional device. The lumen carrying the cable will be sufficiently large along a proximal portion to permit preferential collapse of the cable should rotation of the distal end become impeded. The catheter body may be made of a polymer or plastic material, such as polyetheretherketone (PEEK), which provides adequate bonding stiffness and resistance to kinking from large hoop stresses.

摘要： An ultrasound imaging guidewire, that is inserted into a patient's body. The guidewire has a static central core and an imaging guidewire body comprising an acoustical scanning device. The acoustical scanning device can be rotated to obtain 360 degree acoustical images of a site of interest in the patients body. Furthermore, the imaging guidewire includes a connector that permits the imaging guidewire body to be disengaged from the static central core tip so that the imaging guidewire body can be axially translated to obtain multi-position imaging. The imaging guidewire body is axially translated without losing the original guidewire positioning because the static central core maintains its position in the patient's body.
