Systems And Methods For Sensor Mechanisms For Magnetic Cards And Devices
US Patent:
8628022, Jan 14, 2014
Filed:
May 23, 2012
Appl. No.:
13/478995
Inventors:
Randy L. Rhoades - Swissvale PA, US
James H. Workley - Imperial PA, US
Jeffrey D. Mullen - Pittsburgh PA, US

Assignee:
Dynamics Inc. - Pittsburgh PA
International Classification:
G06K 19/06
US Classification:
235492, 235380
Abstract:
A card exhibiting multiple linear arrays of sensors are provided to detect a presence and movement of an external object (e. g. , a read-head of a magnetic stripe reader). Each sensor of each array of sensors may be independently connected to a dual port of a processor so that the processor may determine a direction in which the card is swiped through a magnetic stripe reader. A portion of sensors of each array of sensors may be shared by a portion of inputs and/or outputs of a single port of a processor. Sensors may be cross-coupled to a single processor port so that forward and reverse directions of a card swipe may nevertheless be detected by a single-port processor of a card.
Optical Keyboard
US Patent:
4713535, Dec 15, 1987
Filed:
Sep 4, 1985
Appl. No.:
6/772553
Inventors:
Randy L. Rhoades - Swissvale PA
International Classification:
H01J 4014, G06F 1540
US Classification:
250221
Abstract:
An optical keyboard includes a plurality of photosensors arranged in an X-Y coordinate system where a plurality of rows represent a plurality of X-axes and a plurality of columns represent a plurality of Y-axes. Each sensor represents input to data processing means. When a beam of light is cast onto a photosensor, the photosensor is actuated to transmit a coded signal to a microprocessor board. The microprocessor board scans the array of photosensors row by row sequentially to identify the column position of an actuated photosensor. The input received from the scanning operation is converted to data and transmitted through either a serial or parallel interface to a computer. Interface circuitry converts the data to a form readable by the computer. Thus, by selectively moving a light source to desired photosensors, specific information can be transmitted to a computer for printout or for operation of other devices remotely controlled by the computer to permit the computer to be operated by individuals unable to perform manual keyboard operations.
