    Abstract: A hyperelastic, soft microfluidic film measures bending curvature using a novel non-differential mechanism. Disclosed embodiments of the elastomer-based solution allows for curvature sensing directly on a bending plane and thus eliminates limitations imposed by strain gauge factor (GF) and sensor thickness (Z). Due to soft lithography microfabrication and design methods the disclosed curvature sensors are elastically soft (modulus 0.1-1 MPa) and stretchable (100-1000% strain). In contrast to existing curvature sensors that measure differential strain, embodiments of the present invention measures curvature directly and allows for arbitrary gauge factor and film thickness. Moreover, the sensor is composed entirely of soft elastomer (PDMS or Ecoflex® and conductive liquid (eutectic gallium indium, (eGaIn)) and thus remains functional even when stretched to several times its natural length. Electrical resistance in the embedded eGaIn microchannel is measured as a function of bending curvature for a variety of sensor designs.

    Abstract: A loss prevention system comprises a protected article and a receiver. The protected article and the receiver are located in the same room. The loss prevention system can help to prevent loss or theft of the protected article. The protected article comprises a transmitter that emits an infrared signal. The infrared signal has a carrier frequency that is modulated to encode a digital signature. The receiver detects infrared signals. The receiver performs an alarm action if the receiver does not detect within a rolling time window an infrared signal having the carrier frequency that is modulated to encode the digital signature.

    Abstract: The invention is a laryngoscope having an image sensor assembly mounted thereto for providing video imaging of a patient's airway passage. The laryngoscope includes a distal end having a tip adapted for contact with tissue of an airway passage and an image sensor assembly mounted to a convex surface of the laryngoscope body so that an image sensor of the assembly is angled away from a tissue contacted by the tip when the laryngoscope is in use. In one embodiment, the image sensor assembly is slidably mounted on a track formed on a curved section of a laryngoscope body so that sliding of the image sensor assembly along the track adjusts the distance of the assembly from a target, and further adjusting the orientation angle of the image sensor assembly.
