摘要： An icing detector is disclosed for detecting presence of ice in static air. An exemplary detector includes an ice collecting surface; a light emitter for emitting a light beam crossing an ice collecting surface, having a prismatic light manipulating window for internally-reflecting the light beam when no ice is present on the ice collecting surfaces, and externally-refracting the light when clear ice is present on the ice collecting surface, wherein the ice collecting surface is oriented to cause standing water to be directed away from the prismatic light manipulating window by gravity; a light sensor in a path of the reflected light; and an annunciator coupled to the light sensor for annunciating the presence of ice when light is sensed by the light sensor.

摘要： A touch-responsive circuit uses an ohmic contact connected via a dc blocking capacitor to the high impedance input of an amplifier. A controllable impedance element shunts the capacitor and amplifier input. When the element is in the high impedance state, a weak voltage induced by touching the ohmic contact causes the amplifier to produce an output signal indicative of such touching. Touch response is disabled when the element is in the low impedance state. Advantageously, the controllable impedance element comprises a series-connected pair of diodes that are selectively forward or reverse biased; the element also may comprise an active electronic device such as a transistor.A data input terminal employs a matrix of ohmic contacts each having an associated touch-responsive circuit. Column scanning is accomplished by conditioning the controllable impedance elements in all but a selected one column to the low impedance state so that touch response is enabled only in that one selected column. The ohmic contacts in each row are connected to a common amplifier for that row. A priority encoder provides an encoded signal designating which amplifier produces a touching-indicative signal, and hence designating which row in the enabled column contains the touched ohmic contact.
