  • Patent number: 11877864
    Abstract: Pressure sensors that can be reliability operated with the maximum current flowing through the device restricted to 10 uA or below, or below 50 uA in a single-fault condition. This can provide at least a reduced need for the final medical device architect to consider potential risks from excessive current to the patient, simplifying the design and manufacturability of the medical device. An additional benefit is that the sensors are generally more accurate at lower current flow, as self-heating of the resistors and parasitic leakages are reduced, if the signal-to-noise problem is resolved.

  • Publication number: 20220332066
    Abstract: A device and method for dispensing air and/or sealant to a tire of a vehicle. Power supply for the air compressor is obtained via powered USB instead of the typical 12 V cigarette lighter connector. The position of the tire which is being inflated can also be determined via the data interface of the USB port. By communication between a compressor control module and the vehicle systems interface, the compressor can automatically switch off when the recommended tire pressure has been reached. The control module can be located in the USB power cord plug, and can provide for changes in voltage to the compressor to maximize power and inflation rate and/or efficiency.

  • Patent number: 11278347
    Abstract: An end effector assembly for an electrosurgical device includes first and second jaw members movable between spaced-apart and approximated positions. The jaw members include tissue-contacting surfaces that define a tissue grasping area. One of the jaw members includes an electrically-insulating body, an interior electrode, and an exterior electrode. The interior electrode is positioned interiorly of outer bounds of the tissue grasping area. A portion of the interior electrode forms part of the tissue-contacting surface. The exterior electrode is positioned exteriorly of the outer bounds of the tissue grasping area. At least one portion of the exterior electrode: extends along the outer back surface of the body, is disposed within the body, and is positioned adjacent the outer bounds of the tissue grasping area. The interior and exterior electrodes are configured to conduct energy through tissue grasped within the tissue grasping area to seal tissue.

  • Patent number: 11096452
    Abstract: A web-adjustment clamp includes a main body including a first lateral channel, a second lateral channel, a fold channel, and an exit channel. The first lateral channel, the second lateral channel, the fold channel, and the exit channel are configured to accept, have passed through, and retain a first webbing. The fold channel may be further configured to accept, have passed through, and retain a second webbing. In at least one embodiment, a locking door is pivotally coupled to the main body. The locking door is configured to be moved between an open position and a closed position. The first webbing is adjustable in relation to the web-adjustment clamp when the locking door is in the open position, and locked in place when the locking door is in the closed position.

  • Patent number: 10653471
    Abstract: Controlling a level of electrosurgical energy provided to tissue based on detected arcing patterns or impedance changes. The drag force imposed on an electrode or blade of an electrosurgical instrument may be controlled by adjusting the level of electrosurgical energy based on the arcing patterns or impedance changes. The arcing patterns or impedance changes may be detected by sensing and analyzing voltage and/or current waveforms of the electrosurgical energy. The current and/or voltage waveform analysis may involve calculating impedance based on the voltage and current waveforms and calculating changes in impedance over time. The waveform analysis may involve detecting harmonic distortion using FFTs, DFTs, Goertzel filters, polyphase demodulation techniques, and/or bandpass filters. The waveform analysis may involve determining a normalized difference or the average phase difference between the voltage and current waveforms.
