摘要： A diagnostic apparatus for examining a region of skin includes a light source for emitting light toward an illumination region of the skin surface. A detector is provided for receiving light from an examination region of the skin surface. A light barrier substantially impervious to the light emitted from the light source intimately engages the skin surface to define a boundary between the illumination region and the examination region.

摘要： A device for dynamically biasing an ion optic element, for example, in a mass spectrometer. The device includes a voltage source, a first ion optical element coupled with the voltage source, a second ion optical element resistively coupled with the first ion optical element; and a pulse generator capacitively coupled with the second ion optical element. The pulse generator is configured to apply a series of pulses to the second ion optical element. In steady state operation, a dynamic voltage bias is generated between the first ion optical element and the second ion optical element. The dynamic voltage bias is controllable by controlling the characteristics of the applied pulses, such as the pulse width, pulse amplitude, and pulse repetition rate of the applied pulses.

摘要： Signal amplifiers having a non-linear transfer function. A high speed (high bandwidth) circuit with a non-linear transfer function over a limited range of input signal is provided. By appropriate choice of components, the non-linear transfer function can be used to accurately approximate any monotonic function such as a square root transfer function. In another aspect, a piecewise non-linear circuit arrangement using a set of non-linear sub-circuits is provided to accurately generate a desired non-linear transfer function over an extended dynamic range of input signal. In one implementation of such a circuit, each of the sub-circuits approximates the desired non-linear function over a portion of the input range.
