  • Publication number: 20240081791
    Abstract: A disposable cartridge can be used for biofluid sample collection, preparation, and mixing with reagents. After sample collection, the cartridge can be inserted into a reader for sample analysis. This system can be used for detecting and measuring analytes, such as drugs, in saliva for example. This is useful for point of test detection of drugs in applications such as workplace drug testing and driving under the influence of drugs testing.

  • Publication number: 20220133522
    Abstract: Intestinal waste management system (102) comprising a device (104) having an anchoring mechanism (106) for anchoring the device (104) once the device (104) is inserted into a stoma. A continence mechanism (108) controls discharge of intestinal waste to outside the intestinal waste management system (102). The continence mechanism (108) comprising abase flange (110) to be placed at the stoma. The base flange 110 to be connected to a discharge channel (114) to form a discharge passage (116) to transport the intestinal waste from intestine to outside, in an open state of the continence mechanism (108). A continence membrane (118) having a first end connected to a distal end of the discharge channel (114). In closed state of the continence mechanism (108), the continence membrane (118) is to fold upon itself to create a constriction within the discharge passage (116) to stop the intestinal waste from flowing out.

  • Patent number: 10093530
    Abstract: A beverage making machine may be arranged to cool a precursor liquid in a tank using a cooling liquid in a cooling container disposed around the tank. The cooling liquid may be freezable to form ice, e.g., to provide the system with improved cooling capacity and/or speed. A plurality of fins may extend between the tank and the cooling container, with each of the plurality of fins being physically attached to the cooling container or the tank and being arranged to conduct heat from the tank and/or from the cooling liquid. The plurality of fins may include first portions attached to the tank and extending outwardly, and second portions attached to the cooling container and extending inwardly. Side surfaces of corresponding first and second portions may be in contact with each other to aid in transferring heat via the fin portions.

  • Publication number: 20180066887
    Abstract: A beverage making machine having a tank may be arranged to carbonate and/or chill liquid in the tank. A thermoelectric device may be thermally coupled to the tank to cool precursor liquid in the tank, and a heat pipe may transfer heat from the thermoelectric device to a heat sink. The heat sink may be located remotely from the thermoelectric device, e.g., in an air duct that helps prevent contact of moisture, dirt, etc. in the duct with the thermoelectric device.

  • Publication number: 20160109165
    Abstract: A beverage making machine having a tank may be arranged to carbonate and/or chill liquid in the tank. A heat sink used to transfer heat from the liquid may be positioned in a duct located in a housing of the machine. Air may flow through the duct from a duct inlet to a duct outlet to receive heat from the heat sink. A precursor liquid supply inlet, e.g., an opening of a water reservoir, may be located near the duct outlet, and the duct may be arranged to conduct any liquid mistakenly provided into the duct outlet to a bottom of the machine, avoiding contact with electronic components of the machine.
