    摘要: A flowmeter is provided that comprises a leadframe assembly (140) and a body (144) disposed at least partially around the leadframe assembly (140). The body (144) has a flow passage therethrough that comprises a first channel (178) having a first port (166), a second channel (180) having a second port (168), and a flow altering element (182) disposed within the second channel (180). First and second pressure sensors (174 and 176) are disposed within the body (144) and coupled to the leadframe assembly (140) for measuring a first pressure within the first channel (178) and a second pressure within the second channel (180), respectively. An integrated circuit (155), which is coupled to the leadframe assembly (140), to the first pressure sensor (174), and to the second pressure sensor (176), is configured to determine the rate of flow through the flow passage from the first pressure and the second pressure.

    摘要: A collapsible suitcase wherein a bottom member has side walls foldably secured thereto with slide fasteners connecting each side wall to form a box-like enclosure. The pull rings of the slide fasteners are locked in closed position by a latch on each corner of an attachable top. The actual volume of the case can be varied according to the extent the slide fasteners are zippered. Rollers are mounted under the bottom of the case to facilitate transport.
