Abstract:
Technologies are generally described to monitor a sweat rate of an area of a skin. A hydration status of a human or non-human entity is monitored based on the sweat rate. The sweat rate is monitored when the sweat rate monitor is detected as sealed against the surface of the skin. The sweat rate monitor is attached to the surface of the skin with an adhesive, or a tape among other schemes to hold the sweat rate monitor in place during a measurement. The sweat rate monitor includes a container to capture an initial amount of sweat that comes out of the surface of the skin. When, the container is detected as filled with the initial amount of sweat, a pump of the sweat rate monitor is actuated to compress the container. The container is compressed to force a volume of the initial amount of sweat in the container out of an ejection port of the sweat rate monitor.
Abstract:
An apparatus is disclosed that may include a substrate that may have a surface, a channel of a volume that may be defined, at least in part, by the substrate, wherein the channel may have a first end and a second end, a valve may be coupled to the channel at the first end, wherein the valve may be configured to allow a fluid to pass into the channel when the valve is open, and a continuity detector, which may be coupled to the channel at the second end, wherein the continuity detector may be activated when the fluid contacts the continuity detector, wherein the continuity detector may further be configured to provide a signal to close the valve and remove the fluid from the channel. A method for calculating a rate of flow of a fluid collected from a bodily surface into a body-worn device is disclosed.
Abstract:
A gradient refractive index light emitting diode is disclosed. The light emitting diode includes a die at least partially encapsulated within a polymer, and nanoparticles dispersed within the polymer along a concentration gradient related to the distance from the die. The refractive index of the nanoparticles is different from the refractive index of the polymer.
Abstract:
A process and an apparatus for controlling temperature loss and shrinkage of meat after an animal is slaughtered for food. Shrinkage is controlled by compressing the meat during cooling, the compression offsetting a natural tendency of the meat to contract and providing a measure of control over the shaping of the meat. Apparatus for the process includes one or more rigid rings for placement around the meat. Each ring is wrapped with a thread secured rigidly to one side of the ring and secured movably to the other side such as to allow the length of thread on the second side of the rigid ring to form at least one winding around the meat. As the meat cools, the thread shrinks, applying the thermal contraction of the thread along the ring to constrict the winding around and thus longitudinally elongate the meat.
Abstract:
Technologies pertaining to a chip with a refractive index gradient, including fabrication thereof, are generally described. The refractive index gradient may be formed by creating atomic scale inclusions throughout a thickness of the chip by inducing nanoporosity into the chip, dissociating and diffusing oxygen into the chip, or performing chemical vapor deposition. One or more integrated circuit (IC) components and optical transceiver devices may be provided by mounting, growing, or etching the IC components and optical transceiver devices at a surface of the chip. The optical transceiver devices may be configured to transmit and/or receive an optical communication signal to and/or from at least one IC component or other optical transceiver device via an optical communication path within the thickness of the chip. The optical communication path may include a direction and distance, within the thickness of the chip, based on the refractive index gradient and angle of incidence.
Abstract:
Technologies are generally described to fabricate an optical circuit board with a non-linear gradient index (GRIN) optical backplane. An optical backplane with a non-linear GRIN may be formed as a circuit board enabling communicative coupling between at least two components on the circuit board and/or between one or more components and an optical interface via one or more optical pathways within the optical backplane. The components may be placed at a location along one or more surfaces of the non-linear GRIN optical backplane based on an approximate angle of incidence for the optical pathways between a component and other components to be coupled to the component. The components may be further placed to enable an optical communication signal projection from the optical interface to arrive at one or more of the placed components.

Abstract:
Technologies are generally described for using different wavelengths and/or using different frequencies of light to encode each of information data and control data in a beam of light and to use the encoded control data to route the encoded information data through a network. Routing may be effected using optical switches configured with transmissive and reflective properties, which may allow transmission of certain encoded control data and may allow reflection of certain information data, depending upon the routing for the travel of the light through the network.
