  • Patent number: 9608188
    Abstract: A method includes preparing a thermoelectric material including p-type or n-type material and first and second caps including transition metal(s). A powder precursor of the first cap can be loaded into a sintering die, punches assembled thereto, and a pre-load applied to form a first pre-pressed structure including a first flat surface. A punch can be removed, a powder precursor of the p-type or n-type material loaded onto that surface, the punch assembled to the die, and a second pre-load applied to form a second pre-pressed structure including a second substantially flat surface. The punch can be removed, a powder precursor of the second cap loaded onto that surface, the first punch assembled to the die, and a third pre-load applied to form a third pre-pressed structure. The third pre-pressed structure can be sintered to form the thermoelectric material; the first or second cap can be coupled to an electrical connector.

  • 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: 5065345
    Abstract: An Interactive Audiovisual Control Mechanism (IACM) which, by exploiting recent advances in CD technology which permit rapid random access of discrete audio information (such as an individual sound or utterance), provides for the first time an interactive computer system in which large amounts of high quality audio and video are presented to the user simultaneously. In the preferred embodiment, this is accomplished via random access to both CD/ROM and VD devices, wherein individual visual frames of the VD are displayed on the system's display monitor for specified periods of time while discrete sounds and utterances from the CD/ROM are played through the system's speaker. Audio from the VD and computer's CPU may also be accessed at the same time, as well as computer graphic still images and animation (due to a well-known "GENLOCK" device).
