    摘要： An ionic liquid piezoelectric gas sensor for the detection of polar and nonpolar organic vapors. The gas sensor can operate at high temperatures with a fast linear response which is also reversible. At high temperatures, the frequency change (Δf) versus concentration (C) curve mirrors the Henry's gas law, such that the concentration of a gas sample in liquid solvent is proportional to the concentration or partial pressure of the sample in gas phase. The gas sensor can be used for quantitative analysis of gas vapors and determination of Henry constants.

    摘要： A neural system is disclosed for processing an exogenous input process to produce a good outward output process with respect to a performance criterion, even if the range of one or both of these processes is necessarily large and/or keeps necessarily expanding during the operation of the neural system. The disclosed neural system comprises a recurrent neural network (RNN) and at least one range extender or reducer, each of which is a dynamic transformer. A range reducer transforms dynamically at least one component of the exogenous input process into inputs to at least one input neuron of said RNN. A range extender transforms dynamically outputs of at least one output neuron of said RNN into at least one component of the outward output process. There are many types of range extender and reducer, which have different degrees of effectiveness and computational costs. For a neural system under design, the types of range extenders and/or reducers are selected jointly with the architecture of the RNN in consideration of the neural system's processing performance with respect to the mentioned performance criterion, the RNN's size and the computational cost of selected range extenders and reducers so as to maximize the cost effectiveness of the neural system.

    摘要： A pump body of an oral irrigator includes a mount, a motor disposed at a rear end away from the mount, a pinion disposed on a shaft of the motor, an annular gear disposed on a shaft member to mesh with the pinion, a cam disposed in the annular gear and adjacent to one side, a linkage secured to the cam, front and rear plungers disposed on a front end of the linkage, and a cylindrical tube disposed on the plungers in the mount. The rotation of the cam only allows the linkage to repetitively moves in a back-and-forth linear motion. Wear between the plungers and the cylindrical tube is decreased to a minimum and leakage is prevented.
