Abstract: Circuitry for an ultrasound device is described. The ultrasound device may include a symmetric switch positioned between a pulser and an ultrasound transducer. The pulser may produce bipolar pulses. The symmetric switch may selectively isolate a receiver from the pulser and the ultrasound transducer during a transmit mode of the device, when the bipolar pulses are provided by the pulser to the ultrasound transducer for transmission, and may selectively permit the receiver to receive signals from the ultrasound transducer during a receive mode. The symmetric switch may be provided with a well switch to remove well capacitances in a signal path of the device.

Abstract: A portable hose cart comprising first and second frame sides, each having a hub bearing surface. The cart also includes a reel positioned between the frame sides and made up of first and second reel flanges, each having a hub rotatably supported by the hub bearing surface of a corresponding frame side, and a number of cross braces joining the reel flanges and definging a support surface for the winding of the hose. A U-shaped handle is connected to the tops of the first and second frame sides. An axle is releasably held by each frame side adjacent its bottom with the axle and the frame sides functioninbg to maintain the frame sides spaced a predetermined distance to hold the reel. The axle rotatably holds first and second wheels which extend beneath the bottom of the frame side. Furthermore, each frame side adjacent its bottom includes a mounting foot for, after removal of the wheels and the handle, permitting the frame sides holding the reel to be positioned on a wall.

Abstract: A portable garden hose cart for windably holding a garden hose and for use in transporting the hose between a storage location and a use location. The cart includes a frame made up of a pair of generally vertical frame sides. A reel for windably receiving the garden hose is positioned between the frame sides with the reel including a pair of reel sides and a hose support surface extending between the reel sides. The cart further includes an oulet tube carried by the reel for rotation therewith and an inlet tube mounted in one of the reel hubs so that the inlet tube does not rotate with the reel. The cart further includes a handle assembly of one-piece molded thermoplastic construction. The assembly has a first leg for connection to one of the frame sides, a second leg for connection to the other frame side and a crossbar interconnecting the legs.

Abstract: The invention relates to an in-line fuseholder which comprises a unitary housing with a cover integral therewith. Two fuse clip insulation displacement contact assemblies are press-fit into the housing. Wire securing mechanisms are provided to facilitate a one-step connection with wires from the exterior. After being closed over the wires, the wire securing mechanisms hold the wires in the housing in a strain-relief fashion. The wire securing mechanisms are also integral with the housing.
