摘要： A position touch sensor having a substrate and a resistive layer disposed on the substrate. At least one pair of electrodes is positioned on the resistive layer. A portion of one electrode is spaced from a portion of another electrode to produce an overlapped resistive region between the spaced portions of the electrodes. An insulating region extends into and terminates in the overlapped resistive region from a resistive region of the resistive layer outside the overlapped resistive region. A method for controlling the flow of current through a resistive layer for converting physical position information on the resistive layer into electrical signals. The method includes determining a dimension of a length of a generally continuous resistive section which is to be located in the resistive layer. The dimension of the length is determined through the use of electrical excitation in the resistive layer. A first insulating region is disposed in the resistive layer to form a first boundary of the generally continuous resistive section. Subsequently and at a distance from the first insulating region essentially equaling the dimension of the length, a second insulating region is disposed in the resistive layer to form a second boundary of the generally continuous resistive section such that current may be conducted through the generally continuous resistive section between the first and second insulating regions.

摘要： Two groups of inclined lines, which are included in a spurious wave scattering means, are formed at opposite angles with respect to each other in the vicinity of an upper edge of a substrate. The angles of the inclined lines are such that they are close to perpendicular toward the central portion of the substrate, and gradually decrease toward the edges thereof. In a similar manner, two other groups inclined lines, which are also included in the spurious wave scattering means, are formed at opposite angles with respect to each other, with gradually changing angles. The spurious waves that reach these regions are diffuse by the inclined lines, so that they are not propagated to converters (sensors). Three rectangular spurious wave scattering means, formed by inclined lines, inclined at angles other than 45°, also function to diffuse and eliminate spurious waves that propagate along the front surface of the substrate.

摘要： A touch screen includes a transmitter capable of delivering an acoustic signal to the touch screen and a receiver adapted to detect acoustic signals on the touch screen and deliver a first signal representative of the detected acoustic signals. An automatic gain control amplifier has an input, output, and control terminal, and is adapted to receive the first signal on the input terminal and deliver an amplified version of the first signal on the output terminal. The control terminal is adapted to receive a control signal that varies the gain of the amplifier. An analog to digital converter is adapted to receive the amplified first signal and deliver a digital representation thereof. A first circuit is adapted to receive one of the amplified first signal and the digital signal, determine the difference between the received signal and a preselected value, and deliver a control signal to the control input of the amplifier. The control signal has a magnitude responsive to the determined difference.

摘要： An acoustic touch panel or “touch screen” utilizes acoustic waves within a sensor substrate to determine the position of touch. The substrate is made of a temperable glass having an attenuation coefficient of less than or equal to about 0.6 dB/cm as determined at the substrate surface for 5.53 MHz Rayleigh waves as measured by the slope of a plot of amplitude versus distance for a signal through a pair of facing 0.5-inch wide wedge transducers mounted on a sample of the glass type under test having sufficient thickness to support Rayleigh wave propagation. An acoustic touch panel with a tempered low-acoustic-loss glass substrate. This makes possible large tempered acoustic touch panels. A glass substrate of the touch sensor comprises SiO2 as the main component with a total content of Na2O, CaO and MgO of 20% by weight or less and a total content of Al2O3, ZrO2, TiO2, B2O3, Y2O3, SnO2, PbO2, In2O3 and K2O of 5% by weight or more.

摘要： A touchscreen is constructed directly on the glass surface of a cathode ray tube (CRT). To solve the problem of insufficient space between the CRT's bezel and frontal region to accommodate the transducers for the touchscreen, the transducers are moved away from the frontal region, to the highly curved shoulder region of the CRT. To preserve acoustic signal strength, the positioning of the transducers is chosen to take advantage of the fact that an acoustic wave on a non-Euclidean surface travels along a geodesic path. Allowance is also made for the acoustic lens and prism effect of the corner regions of the CRT, where the transducer may be located.
