  • Patent number: 11565042
    Abstract: A system and method provides closed-loop sedation, anesthesia, or analgesia by monitoring EEG and automatically adjusting the delivery of sedative, anesthetic, and/or analgesic drugs to maintain that desired level of cortical activity for transportation or evacuation of the injured, and for closed-loop anesthesia during surgical care, and at all echelons of care.
    Type: Grant

  • Patent number: 11444646
    Abstract: The present invention relates to the acquisition, processing, and monitoring of signals, and particularly to the acquisition, processing, and monitoring of electrophysiological signals. More particularly, the present invention relates to the acquisition, processing, and monitoring electroencephalography (EEG) signals representing cortical/brain activity. Further, the present invention relates to a method and apparatus for acquiring such signals in the presence of electrical interference and noise. More particularly, the present invention relates to systems and methods for filtering out and rejecting electrical interference and noise while maintaining or improving the quality of the underlying physiological signal and preventing perturbation or introduction of artifacts into the physiological signal.

  • Patent number: 11109789
    Abstract: A system and method for using electroencephalographic (EEG) signals to monitor brain function, preferably detect occurrence of traumatic brain injury (TBI) to screen, assess, and potentially provide mitigating treatment to improve short and long term adverse outcomes of mild TBI (mTBI) and TBI. The system and method provides a readily available tool to assist in accurate and objective assessment of subjects with TBI, immediately at the point of injury (POI), during transportation, or upon arrival at a care facility, that preferably is applicable without advanced training or expertise.

  • Patent number: 10842932
    Abstract: The present invention relates to the titration and delivery of anesthetic and sedative medications to a subject. Further, the present invention relates to a device and methods for titrating and delivering such medications in a semi-automated or fully automated manner and which can be monitoring and controlled remotely. Even still further, the present invention relates to such a device that can perform the titration and delivery of medication in a manner that minimalizes occlusion and prevents back flow of the medication. More particularly, the present invention relates to a device for titration and delivery of medication using a non-concentric pumping mechanism that gradual or progressively increases and decreases occlusion in the medication delivery line within the pump to minimize and/or prevent sudden formation and release of occlusion in order to provide more steady and continuous flow of the medication through the device to the subject.

  • Patent number: 8502763
    Abstract: The invention features electronic skin including an active layer formed of bistable cholesteric liquid crystal material and articles comprising the skin, the electronic skin having uniform gray scale reflectivity. Also featured is method for producing suitable reduction pulses that will provide a display (e.g., the electronic skin) with uniform gray scale reflectivity. Reduction pulses of narrow width are used to create uniform levels of gray in the electronic skin to overcome display imperfections that cause discontinuity in the gray scale reflectivity.
