Abstract: The present invention relates to a keyless entry system that contains a visual random code generator so that the possible input pattern is different every time a user accesses the system. A keypad device containing an input device and a display are electronically connected to a processor containing the visual random code generator. Positions and associated values are displayed on the input device, such as a touch sensitive screen, allowing the user to enter an access code. The visual random code generator randomizes and controls the input pattern displayed so that the input pattern changes each time the system is accessed.

Abstract: A touch sensing system includes one or more touch sensors, a temperature sensor, an output driver and a controller configured to set the output driver to a first state when the controller deems the sensor(s) to be in a touched state and to set the output driver to a second state when the controller deems the sensor(s) to be in a untouched state. The controller sets a touch sensitivity threshold for the sensors as a function of temperature data the controller receives from the temperature sensor.
