  • Patent number: 11653860
    Abstract: Recommendations based on continuous glucose monitoring (CGM) are described. Given the number of people that wear CGM systems and because CGM systems produce measurements continuously, a platform that provides a CGM system may have an enormous amount of data. This amount of data is practically, if not actually, impossible for humans to process. In implementations, a CGM platform includes a data analytics platform that obtains glucose measurements provided by a CGM system and also obtains additional data associated with a user. The data analytics platform processes these measurements and the additional data to predict a health indicator by using models. This prediction serves as a basis for generating a recommendation, such as a message recommending the user take action or adopt a behavior to mitigate a predicted negative health condition.

  • Publication number: 20170062690
    Abstract: A thermoelectric generating unit includes a hot-side heat exchanger (HHX) including one or more discrete channels and substantially flat first and second cold-side plates. A first plurality of thermoelectric devices are between the first cold-side plate and a first side of the HHX; and a second plurality of thermoelectric devices can be between the second cold-side plate and a second side of the HHX. Fasteners can extend between the first and second cold-side plates at locations outside of the HHX channel(s). The fasteners can be disposed within gaps between the thermoelectric devices of the first plurality and within gaps between the thermoelectric devices of the second plurality. The fasteners can compress the first plurality of thermoelectric devices between the first cold-side plate and the first side of the HHX and can compress the second plurality of thermoelectric devices between the second cold-side plate and the second side of the HHX.

  • Patent number: 9318682
    Abstract: Apparatus and method for generating electricity. The apparatus includes one or more first components configured to extract heat from at least a first fluid flow at a first temperature to one or more devices configured to convert thermal energy to electric energy. The first fluid flow is in a first direction. Additionally, the apparatus includes one or more second components configured to transfer heat from the one or more devices to at least a second fluid flow at a second temperature. The second temperature is lower than the first temperature, and the second fluid flow is in a second direction. Each first part of the first fluid flow corresponds to a first shortest distance to the one or more devices, and the first shortest distance is less than half the square root of the total free flow area for a corresponding first cross-section of the first fluid flow.

  • Publication number: 20160099398
    Abstract: A thermoelectric generator includes a tapered inlet manifold including first and second non-parallel sides; first and second pluralities of outlet manifolds; and thermoelectric generating units (TGUs) each including a hot-side heat exchanger (HHX) with inlet and outlet; a cold-side heat exchanger (CHX); and thermoelectric devices arranged between the HHX and CHX. The inlets of some of the HHXs receive exhaust gas from the first side of the tapered inlet manifold and the outlets of those HHXs are coupled to outlet manifolds of the first plurality of outlet manifolds. The inlets of other of the HHXs receive exhaust gas from the second side of the tapered inlet manifold and the outlets of those HHXs are coupled to outlet manifolds of the second plurality of outlet manifolds. The thermoelectric devices can generate electricity responsive to a temperature differential between the exhaust gas and the CHXs.
