Abstract:
Methods to systematize the development of machines using inexpensive, fast, and convenient fabrication processes are disclosed. In an embodiment, a folding pattern and corresponding circuit design can provide the blueprints for fabrication. The folding pattern may be provided (e.g. laser machined) on a flat sheet of substrate material, such as a polymer. The circuit pattern may be generated by etching or applying (e.g. sputtering) a copper foil layer onto the substrate. Circuit components and actuators may then be added at specified locations. The flat substrate may then be folded along the predefined locations to form the final machine. The machine may operate autonomously to perform a task.
Abstract:
A device has a capacitive surface and a light source. A user of the device uses the capacitive surface to change the intensity of light emitted by the light source. To increase and decrease the intensity of the light emitted by the light source, the user touches the capacitive surface with one or more fingers.
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:
An apparatus, system and method for providing health-care equipment in a plurality of customizable configurations. A configuration includes a selection and arrangement of health-care equipment modules that each provide specialized support for the provision of health care, including the measurement of physiological parameters. Various types of configurations include those adapted to be mounted upon a desk top or a wall surface, or adapted for wheel mounting or hand-carriable mobile configurations.
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:
An apparatus for medical inspection comprising a hand-held medical diagnostic instrument having a battery pack for providing energy to a light source for illuminating the target area, a housing, a charger for charger the battery pack that is integral with the housing and adapted to provide electric energy to the battery pack to charge the battery pack, a video adapter detachably coupled to the medical diagnostic instrument, video processing circuitry contained within the housing and an umbilicus for connecting the video adapter to the video processing circuitry.
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.
