A system for monitoring the health and safety of recumbent individuals. In some embodiments, the bed monitor system comprises a wired or wireless sensor mat which may be positioned upon a bed mattress and underneath a bedsheet. Multiple RFID tag sensors embedded within the sensor mat can detect physical, bodily, and environmental attributes and transmit this information to a controller box for further processing. Turn regiment, prohibited body positions, imminent fall danger, and bed occupancy may therefore be tracked and updated accordingly. In some embodiments, the system can dynamically generate positional images of a body proximate to the sensor mat in order to identify adverse conditions requiring attention. Incontinence discharges can also be detected by sensors and algorithms which can differentiate urinary from fecal incontinence events. Various embodiments of the system are portable, allowing for a rapid set-up within hospital venues and within other care facilities.

Intelligent multifunction bed monitor

A system comprises a series of passive RFID tag sensors each embedded on top of its own matching antenna inside a flexible substrate. The sensors are driven by a controller-transceiver. The controller-transceiver sends RF signals through an antenna to each RFID tag sensor and receives data transmitted back from the same sensors. Sensors are embedded in a flexible substrate positioned under an unaltered incontinence absorbent pad and juxtaposed to derive further information. Multiple sensors provide sensing of physical-environmental data in addition to moisture. The controller makes intelligent and positive incontinence determinations by relating data to profiles indicative of correlation to incontinence conditions.

Intelligent incontinence monitor generating and utilizing incontinence profiles

A system for monitoring patient incontinence. A sensor module is positioned next to an impermeable layer of absorbent pad used for urinary or other incontinence. A wired embodiment has the sensor module wired to an external controller. In the wireless embodiment, a radio frequency identification (RFID) tag includes an antenna, moisture sensor, and radio frequency integrated circuit (RFIC). A rewritable memory is included in the RFIC to record identifying information associated with the patient. The identifying information is programmed in the RFID tag when it is in the range of an RFID writer. A controller-transceiver in this intelligent underpad monitor system provides excitation energy to operate the RFID tag. The controller-transceiver constantly interrogates the RFID tag to detect any incontinence alarm signal. When incontinence happens, the alarm signal is sent to the controller-transceiver along with user information in the RFID tag memory. In both wired and wired embodiments, the controller, which is a microprocessor, will process and screen the information as needed to communicate with the hospital information system.

The radiation shielding composition and method of the present invention relate to a conformal coating material composed of a matrix of densely packed radiation shielding particles, which are disbursed within a binder. The shielding composition is applied to objects to be protected such as integrated circuits, or to packages therefor, as well as for protecting animals including humans from unwanted exposure to radiation in outer space or other environments.
