摘要： A method and apparatus for digitally identifying the location of an applied force by utilizing the changes in the properties of a magnetic material in response to the application of a force to the material. In one embodiment, a matrix of similarly-oriented magnetic cores is arranged so that the rows and columns of cores are sequentially driven by a driving signal from a core driver circuit. Sense lines are provided for both the rows and the columns of cores and are arranged so that the row sense lines thread a like number of cores in each row in each of a first direction and a second or opposite direction. The column sense lines are also located so that a like number of cores in each column are threaded in each of a first direction and a second direction. In the absence of a force applied to any one of the cores, the resultant sensed output from the column sense lines as the rows of cores are sequentially driven is substantially zero, since the sensed output produced by the cores threaded by the sense lines in one direction is cancelled by the sensed output produced by the cores threaded by the sense lines in a second direction. When a force is applied to a core, a signal is sensed by the column sense lines during the sequential driving of the rows of cores which cause a control circuit to actuate a counter to indicate the X-coordinate of the location of the force. Similarly, when the columns of cores are being driven, a signal is sensed by the row sense line during the sequential driving of the columns of cores which causes the control circuit to indicate a count on a Y-counter to indicate the Y-coordinate of the force. The respective coordinates thus indicate the location of the force. In an alternative embodiment, the column drive lines are used as sensing lines when the rows of cores are being sequentially driven, while the row drive lines are used as the sense lines when the columns of cores are sequentially driven. Circuit modifications to effect a reduction in the number of leads threading each core for the alternative embodiment are thus disclosed.

摘要： A solid state switch construction employing a saturable magnetic core switch. The switch has a keystem of magnetic material to change the magnetic property of the saturable magnetic core to effect switching of the signal information by transformer coupling. The keystem has a pair of legs extending on opposite sides of the magnetic core with two permanent magnets secured thereto. When the keystem is not depressed the magnets are located adjacent opposite sides of the core so that the magnetic flux path is formed through the magnetic core, the keystem, and the two permanent magnets to thereby saturate the magnetic core and prevent transformer coupling. When the keystem is depressed, the permanent magnets are moved away from the magnetic core to unsaturate it and variations in the magnetic field effect witching of signal information. The magnetic core is readily removable from the key construction without electrically disconnecting the leads from the circuitry to which they are connected should a malfunction of the switch body or keystem occur. The magnetic core is firmly but removably held within the switch body by a metal clip.

摘要： The disclosure describes a keyboard switch having two magnetic cores and a plurality of permanent magnets. The permanent magnets are mounted on a keystem and are movable with respect to the cores to change the flux density in the cores and thus vary the coupling between an AC drive winding and one or more secondary output windings threading each core. Non-magnetic regions separate the permanent magnets and these regions are positioned such that flux changes in one core, resulting from movement of the keystem, are out of phase with the flux changes in the second core. The output signal from one core may be used to strobe or sample the output signals appearing on the secondary windings of the other core. When a plurality of the switches are incorporated in a keyboard, the switches possess an inherent ''''roll-over'''' capability. The disclosure also describes a keyboard circuit employing a plurality of the switches.

摘要： Transmission of electric signals from a primary coil to a secondary coil can be effectively controlled by moving a magnet to and from a magnetic core of ferromagnetic substance, such as iron, or a ferrimagnetic substance, such as ferrite. Similar control is obtainable by changing the DC control current in a third coil wound on the magnetic core. By utilizing the abovementioned controls, various electric devices, for instance, a keyboard switch without contacts suitable for an electronic calculator, a variable inductor, a vibration-free AC relay, etc. can be made.

摘要： A self-encoding keyboard which employs eddy current shorting effects for generating coded digital electrical signals representative of actuated keys. Each key includes a metal element which upon actuation of the key is brought into close proximity to a corresponding group of stacked printed circuit windings so as to produce an eddy current shorting effect which is detected and used to produce a group of coded digital output signals uniquely representative of the actuated key. Winding encoding arrangements employing two windings per binary digit as well as a single winding per digit are described.

摘要： A mechanically actuated magnetic switch arrangement includes a plurality of closed magnetic cores and a plurality of windings on each core. A magnetic saturation element is near each core, and means respond to actuation of a switch lever associated with each core for permitting or preventing saturation of that core. A rest-position loop is connected to one winding on each core and delivers an input signal to an amplifier. The output of the amplifier is connected to an electronic lock for preventing more than one signal at a time from emanating from the switch arrangement.
