  • Publication number: 20100073162
    Abstract: A device and method for reminding people to maintain hand hygiene. Further a device and method for reminding people to perform hand washing and obtaining hand hygiene compliance data in a patient care environment, which may be a hospital, a nursing home, or a food service facility, which may be a restaurant or cafeteria. A device and method for using accelerometry and/or additional sensor cues, which may include the sound of running water and/or alcohol odor, for sensing when a person has washed their hands, and for using accelerometry information and other cues to determine when a person has touched something, thereby contaminating his/her hands.

  • Publication number: 20090299229
    Abstract: The invention relates to a form of a passive or active annunciator that solves the problem of reminding a caregiver to reposition a patient at risk for aspiration usually located in an adjustable bed to some predetermined angular position. The annunciator may take the form of an inclinometer (100) that measures the angle of the bed (160) relative to a local gravity reference or a goniometer that measures the angle between the horizontal (140) and elevated portions (130) of the bed. The invention reminds the caregiver of the patient at risk for aspiration to maintain or reestablish the elevation of the torso of the patient at risk for aspiration to at least 30 degrees up to 45 degrees above the local horizontal to prevent or reduce the incidence of aspiration.

  • Publication number: 20090223787
    Abstract: The invention relates to a form of a tilt switch that solves the problem of poor electrical contact, excessive/unpredictable hysteresis, high contact resistance, short life and/or electrical bounce. The tilt switch uses conventional ball-in-tube construction and adds a graphite powder film to all electrically conductive surfaces in the switch. This non-mercury tilt switch provides additional features such as enhanced electrical contact, reduced or eliminated hysteresis, lowered contact resistance, increased contact life and eliminates electrical bounce.
