  • Publication number: 20180017292
    Abstract: Disclosed are cascade refrigerant systems for providing cooling of air located in an enclosure that is occupied by or which will be exposed to humans or other animals during normal use, wherein systems includes; (1) a first, relatively low temperature heat transfer circuit having a first evaporator located within the enclosure and a first heat transfer fluid in the low temperature heat transfer circuit; (2) a second heat transfer circuit located substantially outside the enclosure comprising a second heat transfer fluid; (3) a heat exchanger which serves as the condenser in the low temperature circuit thermally coupled with the high temperature circuit by virtue of rejecting heat into the second heat transfer fluid; and (4) in the high temperature loop of a heat exchanger which transfers heat from the second heat transfer fluid exiting from a high temperature condenser to the portion of the second heat transfer fluid which is traveling to the suction side of the compressor.

  • Publication number: 20170312183
    Abstract: There is provided an apparatus for monitoring compliance, facilitating automatic dispensing and childproofing strip packaged medication. In one embodiment a dispenser advances a packet, controls advancement of the packet and detects the presence and absence of the packet, including electronic circuitry for recording events. A replicate for strip package medication can have packets with an open conductive trace, each packet being rupturable at a location to interrupt conductivity of the conductive trace. When the conductive trace of one of the packets completes an external circuit, the circuit is interrupted when the packet is ruptured. In another aspect, each packet has a tuned antenna that is tuned to an external transceiver which detects the detuning of each antenna. In a method of making a replicate for strip package medication, conductive ink is printed on a surface of each packet of the replicate and longitudinal edges of the replicate are reinforced.

  • Publication number: 20170273547
    Abstract: Embodiments of a system and method for processing and recognizing non-contact types of human input to prevent contamination are generally described herein. In example embodiments, human input is captured, recognized, and used to provide active input for control or data entry into a user interface, The human input may be provided in variety of forms detectable by recognition techniques such as speech recognition, gesture recognition, identification recognition, and facial recognition. In one example, the human input recognition techniques are used in connection with a device cleaning workflow used to obtain data and human input during cleaning procedures while minimizing cross-contamination between the contaminated device or person and other objects or persons. In another example, the human input recognition techniques are used in connection with a device tracking workflow used to obtain data and human input while tracking interactions with and locations of the contaminated or uncontaminated device.

  • Patent number: 9101530
    Abstract: There is provided a content use monitoring package and method of making the same. The package includes a cover layer followed by a blister card layer. The third layer comprises an electronic sensor monitoring tag connected to a rupturable layer imprinted with a conductive grid. The grid is printed on a non-conductive, non paperboard rupturable substrate and is aligned with associated blisters in the blister card. To ensure precise and reliable electrical continuity between the tag and grid they are connected by a low or zero insertion force flat flex connector which connection is also reversible. The tag includes re-usable electronic circuitry and power source. The fourth and bottom layer is a backing which contains a mechanism to tear open the package and remove the tag by unplugging the flex circuit connector. The tag can then be reused and the battery replaced as required.
