A programmable resistance circuit provides a selected resistance by configuring a reference resistor to exhibit an effective resistance, in an operational sense, by achieving an average output voltage between a source line and a return line in the programmable resistance circuit. The average output voltage corresponds to the effective resistance. The effective resistance is achieved by utilizing a modulated voltage source to bias a transistor and intermittently draw current across the reference resistor according to the duty cycle of the modulated voltage source. A programmed resistance circuit can produce a selected resistance corresponding to button selection zones of a vehicle user interface when connected to a remote circuit that acts according to a user selection.

Apparatus and system for a programmable resistance circuit

A switch assembly that provides haptic feedback includes a printed circuit board (PCB) having a first planar surface that faces in a first direction and a second planar surface that faces in a second direction, the second direction being opposite from the first direction, a touch plate having a first surface that faces in the first direction and a second surface that faces in the second direction, wherein the first surface of the touch plate is proximate the second planar surface of the PCB, and a haptic exciter that has a conductive coil of wire having a hollow inner core and a magnet that is at least partially disposed within the hollow inner core of the coil of wire such that the magnet alternatively moves in the first and second directions as an alternating current passes through the conductive coil of wire.

In a touch screen environment, a computer calculates an effective position and updated effective positions of simultaneous or sequential touch events by calculating average coordinates of the touch events using force measurements. The average coordinates correspond to computerized maps of the user interface and z coordinates correspond to an average force at the x and y locations. The effective positions are used to determine if the user's touches move across multiple virtual input areas having priority and non-priority relationships. By expanding a virtual input area of the map for those areas having a priority label relative to a different non-priority virtual input area, the computer effectuates appropriate functions depending on where the most recent effective position lies.
