A sensor system includes a touch screen and a force sensor. The touch screen has a first and second surface and detects a first surface touch and converts it to data indicative of an X, Y coordinate position upon the touch screen first surface. The force sensor contacts the touch screen second surface and substantially extends around the perimeter of the touch screen second surface. The force sensor measures the force exerted by the first surface touch in the form of force data.
A force sensing resistor (FSR) includes a substrate having separated electrically conductive traces and another substrate having a resistive layer in which the substrates are subjected to a biasing force such that the substrates contact one another with the resistive layer electrically connecting the traces with a resistance inversely dependent on the biasing force. Upon an external force applied towards a substrate, the substrates contact one another with a total force which is the sum of the forces with the resistive layer electrically connecting the traces with a resistance inversely dependent on the total force. An FSR output which is a function of the resistance is measured. Whether a change in magnitude of the FSR output during a time interval is greater than a threshold is determined. A touch applied on the FSR is detected during the time interval if the change is greater than the threshold.

Chemical sensors whose active element exhibits both a visual change in color and a measurable change in electrical resistance when exposed to an analyte to which it selectively reacts are provided. These sensor have several unique features including vastly improved stability measured in years, irreversible visual changes and surprisingly reversible electrical changes. The combined unique features enable a new generation of ultra low power alerting, alarming and readout devices for hydrazines and other strongly reducing chemicals.

A touch input device includes two or more interleaved scroll sensors. A common area is interposed between two of the scroll sensors. A sense line snakes through the common area. Scrolling pressure applied to a sense layer causes the sense layer to contact and electrically connect the sense line to the scroll sensors thereby permitting the scrolling pressure position to be determined by measuring a voltage on the sense line. The scroll sensors are potentiometric and may be linear strip scroll sensors or rotary ring scroll sensors. The interleaved scroll sensors with the common area allow smooth scrolling action from one major leg to another major leg.
A method for implementing a control function via a sensor having a touch sensitive control input surface. The method includes detecting a contact with the touch sensitive control input surface, determining a pressure value corresponding to the contact, and initiating a control function from a set of possible control functions based at least in part on the pressure value.
The present invention determines angular position using a potentiometric touch sensor. The sensor has an annular pattern of resistive material on a portion of a bottom substrate top surface. Conductive drive lines and fixed potential conductive traces radially traverse the bottom substrate top surface and are electrically coupled to the resistive material. Conductive sense traces radially traverse the bottom substrate top surface. A conductive layer on a bottom surface of a top substrate is positioned above the bottom substrate top surface. A pressure applied to the top substrate and/or the bottom substrate electrically couples a portion of a conductive sense trace to a portion of the annular pattern and/or a fixed potential conductive trace. The angular position of the applied pressure is determined by measuring at least one electrical parameter between a conductive drive line and a conductive sense line having the conductive sense traces.

At least one of these control functions accepts parametric control input. A first touch is received at one of the regions on the input surface. The control function assigned to the touched region is selected. If the selected control function is one of the control functions accepting parametric control input, a second touch on the input surface is received as parametric control input during an activation period for the selected control function. The second touch may be received as parametric control input at any point of the input surface.
