    Abstract: Devices having one primary transistor, or a plurality of primary transistors in parallel, protect electrical circuits from overcurrent conditions. Optionally, the devices have only two terminals and require no auxiliary power to operate. In those devices, the voltage drop across the device provides the electrical energy to power the device. A third or fourth terminal can appear in further devices, allowing additional overcurrent and overvoltage monitoring opportunities. Autocatalytic voltage conversion allows certain devices to rapidly limit or block nascent overcurrents.

  • Patent number: 10431032
    Abstract: In order to monitor the number of plug cycles of a plug, such as a plug of a charging cable for an electric car, a plug cycle counter associated with the plug is counted up in an electronic memory after every plug cycle. A warning can thus be issued when a permitted quantity of plug cycles for the plug has been exceeded. Alternatively, the electrical connection at a charging station for an electric car or at a data cable for an automation system can also be cut off if the service life of the plug has been exceeded. High availability of the plug is thereby achieved, because the corresponding cable can be replaced in a timely manner. A hazard to persons due to defective current-carrying parts is also prevented.

A measurement power meter measures power of a signal to the first load. The measurement power meter measures voltage across the first load; measures current through the first load; and multiplies the measured voltage by the measured current to generate a measured power signal proportional to power delivered to the first load. The power detector includes a processor to calculate power delivered to the second load, and to generate a power delivered to the first load.

  • Patent number: 9895533
    Abstract: Embodiments described herein include a controller (22). The controller includes at least one interface (62) that couples the controller to stimulation circuitry (24), which includes a pair of electrodes (26a, 26b), and to measuring circuitry, and further includes controller circuitry (64). While the electrodes are coupled to skin (60) of a subject, the controller circuitry, via the interface, drives the stimulation circuitry to (i) pass a plurality of stimulating pulses (32) between the electrodes, and (ii) pass one or more reference pulses (34) between the electrodes, the reference pulses being different from each of the stimulating pulses. The controller receives, from the measuring circuitry, an impedance between the electrodes that is measured using the reference pulses. In response to the impedance measured using the reference pulses, but not in response to any impedance measured using the stimulating pulses, the controller circuitry controls the stimulation procedure.

  • Patent number: 9724508
    Abstract: Disclosed is an improved external cable box assembly and external trial stimulator (ETS) for use with an implantable medical device. The improved external cable box assembly has memory and logic circuitry embedded in it which allows the cable box to be identified. Associated logic circuitry in the improved ETS allows the ETS to read and write characteristics—such as electronic identifiers or cable addresses—of the external cable box assemblies and to store the values of those characteristics in its memory, associating characteristic values with each of its ports. If the external cable box assemblies become unplugged from the ETS and then are reconnected to incorrect ports on the ETS, logic in the ETS will either alert the patient to swap the port locations of the external stimulation cables, or the ETS will automatically reroute the correct therapy through each port.

  • Patent number: 8838205
    Abstract: A robot-guided system to assist orthopaedic surgeons in performing orthopaedic surgical procedures on pre-positioned inserts, including for the fixation of bone fractures, and especially for use in long bone distal intramedullary locking procedures. The system provides a mechanical guide for drilling the holes for distal screws in intramedullary nailing surgery. The drill guide is automatically positioned by the robot relative to the distal locking nail holes, using data derived from only a small number of X-ray fluoroscopic images. The system allows the performance of the locking procedure without trial and error, thus enabling the procedure to be successfully performed by less experienced surgeons, reduces exposure of patient and operating room personnel to radiation, shortens the intra-operative time, and thus reduces post-operative complications.
