摘要： A SELF-ADJUSTING DETECTING AND AMPLIFYING CIRCUIT IS DESCRIBED FOR USE WITH ELECTRICALLY OPERABLE DETECTING ELE MENTS SUCH AS A CADMIUM SULPHIDE PHOTO CONDUCTOR FOR SENSING SHORT TERM CHANGES IN A PHYSICAL PHENOMENON SUCH AS A LIGHT PULSE THAT GOES FROM A FIRST CONDITION OR LEVEL OF INTENSITY TO A SECOND DIFFERENT CONDITION OR LEVEL OF INTENSITY AS DISTINGUISHED FROM LONGER TERM CHANGES IN OPERATING CONDITION OF THE DETECTING ELEMENT DUE TO TEMPERATURE EFFECTS, AGING, DUST OR DIRT IN THE OPTICAL PATH TO THE PHOTO CONDUCTOR, ETC. A FIELD EFFECT TRANSISTOR IS CONNECTED IN SERIES CIRCUIT RELATIONSHIP WITH A PHOTO CONDUCTOR DETECTING ELEMENT AND THE SERIES CIRCUIT THUS COMPRISED IS CONNECTED ACROSS A SOURCE OF ELECTRIC ENERGY. AN OUTPUT CIRCUIT IS CONNECTED ACROSS THE PHOTO CONDUCTOR AND IS RESPONSIVE TO BOTH LONG AND SHORT TERM CHANGES IN OPERATING CONDITION OF THE DETECTING ELEMENT. A FEEDBACK CIRCUIT COMPRISING A RESISTOR-CAPACITOR NETWORK HAVING A LONG RC TIME CONSTANT IS COUPLED BETWEEN THE OUTPUT CIRCUIT AND THE INPUT TO THE FIELD EFFECT TRANSISTOR FOR CONTROLLING ITS CONDUCTIVITY. THE FEEDBACK SIGNAL IS ADJUSTED SO AS TO CONTROL THE CONDUCTIVITY OF THE FIELD EFFECT TRANSISTOR IN A MANNER TO MAINTAIN CONSTANT VOLTAGE ACROSS THE PHOT CONDUCTOR DETECTING ELEMENT. AN OUTPUT INDICATING MEANS SUCH AS A METER IS COUPLED ACROSS THE OUTPUT CIRCUIT THROUGH A COUPLING CAPACITOR, PULSED, TRANSIENT COUPLING TRANSFORMER OR THE LIKE AND IS RESPONSIVE SUBSTANTIALLY ONLY TO SHORT TERM CHANGES IN SIGNAL LEVEL. THE D.C. COMPONENT OF THE SIGNAL INCLUDING LONG TERM CHANGES DUE TO UNDESIRED TEMPERATURE EFFECTS, AGING, ETC. IS BLOCKED BY THE COUPLING CAPACITOR, COUPLING TRANSFORMER, OR THE LIKE. BY THIS MEANS, SENSITIVITY FO THE CIRCUIT IS MAINTAINED DESPITE DUST ACCUMULATION OR OTHER UNDESIRED LIGHT PATH MODULATING EFFECTS WITH ONLY A RELATIVELY SIMPLE INEXPENSIVE CIRCUIT.

摘要： A keyswitch includes a circuit board, a bottom board abutting against the circuit board, a cap, a light receiver and a light emitter disposed on the circuit board and opposite to each other, a base disposed on the circuit board, a cover disposed on the base, a first elastic member disposed through the cover and the base, a support device, and a second elastic member fixed to the base and having a flexible rod. The support device is movably connected to the cap and bottom board and has a sheet structure. When the cap is pressed, the sheet structure blocks light transmission between the light emitter and the light receiver to generate a triggering signal. When the cap is pressed to make the flexible rod deform downward with the sheet structure and then cross the sheet structure, the flexible rod is released to collide with the cover to make sound.
