    摘要: An ESD protection device, which is arranged to be active at a triggering voltage (Vt1) for providing ESD protection, comprises a first region of the first conductivity type formed in a semiconductor layer of the first conductivity type, the first region extending from a surface of the semiconductor layer and being coupled to a first current electrode (C) of the semiconductor device, a well region of a second conductivity type formed in the semiconductor layer extending from the surface of the semiconductor layer, and a second region of the second conductivity type formed in the well region, the second region being coupled to a second current electrode (B). The ESD protection device further comprises a floating region of the second conductivity type formed in the semiconductor layer between the first current electrode (C) and the well region and extending from the surface of the semiconductor layer a predetermined depth. The floating region is separated from the well region by a predetermined distance, a value of which is selected such that the floating region is located within a depletion region of a PN junction between the well region and the semiconductor layer when the ESD protection device is active. The floating region has a doping concentration selected such that the floating region is not fully depleted when the ESD protection device is active and the predetermined depth is selected such that the floating region modifies a space charge region near the PN junction. An ESD protection device according to a second embodiment is also disclosed.

    摘要: A preferred frequency is identified, being usable to stimulate a neurological target within a mammalian body using at least one microelectrode positioned at or near the target. To establish efficient and effective stimulation, an impedance analyzer is provided for measuring electrical impedance values indicative of a microelectrode-tissue interface across a range of different frequencies. A preferred one of the measured electrical impedance values is identified as being closest to a pure resistance. The neurological target can then be stimulated at or near the frequency associated with the preferred impedance value (peak resistance frequency), thereby promoting desirable traits, such as optimum charge transfer, minimum signal distortion, increased stimulation efficiency, and prevention of microelectrode corrosion. The peak resistance frequency can be used to determine an preferred pulse shape. A target can be identified by microelectrode measurements of neuronal activity and/or impedance magnitude at peak resistance frequency.

    摘要: A method for discrimination of particles, preferably biological cells, in a measurement channel having a liquid for transporting the particles by impedance spectroscopy. Pairs of measurement and reference electrodes are arranged in the measurement channel. During movement of a particle through the pair of measurement electrodes, the pairs of measurement and reference electrodes are admitted with same input signals having different frequencies. Measurement values at the measurement and reference electrodes are compared to determine particle specific values for the particle being moved through the measurement channel. The particle specific values for the different frequencies are normalized to a particle specific basic value at a basic frequency; and then the normalized particle specific values are compared with corresponding values of at least one reference particle at the same different frequencies. The comparison shows changes in the capacitance or in the conductance of the particle, which are used in discriminating the particle.

    摘要: An implantable drug infusion device which features an improved flow regulator which permits the flow rate to be independent of reservoir pressure within a given pressure range. The flow regulator features a membrane having a hole, the membrane itself positioned above a bottom layer such that sufficient deflection of the membrane causes the membrane to engage against the bottom layer. As liquid flows through the hole a drag force is applied to the edge of the hole resulting in a deflection of the membrane. Once contact is made between the membrane and the bottom layer, then flow reduced. In a further embodiment the bottom layer features a variable flow channel such that upon membrane deflection flow may only proceed through the hole and through the flow channel. By tailoring the shape and length of the variable flow channel the flow characteristics of the regulator versus pressure may be adjusted. In a further embodiment the flow regulator also features a flow sensor integrated therewith. This integrated sensor provides a measurement of flow and may be coupled to the flow regulator to provide feedback thereto.

    摘要: An indium phosphide photovoltaic cell is provided where one or more quantum wells are introduced between the conventional p-conductivity and n-conductivity indium phosphide layer. The approach allows the cell to convert the light over a wider range of wavelengths than a conventional single junction cell and in particular convert efficiently transparency losses of the indium phosphide conventional cell. The approach hence may be used to increase the cell current output. A method of fabrication of photovoltaic devices is provided where ternary InAsP and InGaAs alloys are used as well material in the quantum well region and results in an increase of the cell current output.
