摘要： The present invention is directed to a multilayer substrate for use in touchscreen and touch sensor applications. The substrate, including a microsheet, a polymer sheet, and a plate supports the propagation of acoustic waves, including Love waves and Rayleigh-like waves. The microsheet and plate may be fabricated from glass, metal, or other suitable materials depending on the desired application for the touchscreen. The polymer sheet may be fabricated from polystyrene, polyacrylates, polyether sulfones, or polycyclic olefins. The disclosed touchscreen substrates are thin but durable and have increased touch sensitivity with decreased sensitivity to water and other surface contaminants.

摘要： A touch sensor comprises a substrate capable of propagating acoustic waves and includes a first surface having a touch sensitive region. A first sidewall intersects the first surface along a first edge. The first edge is configured to propagate a first acoustic wave along the first edge. The first acoustic wave may be a one-dimensional edge wave. A wave converter converts the first acoustic wave to a second acoustic wave, and the first surface is configured to propagate the second acoustic wave across the touch sensitive region.

摘要： A method and apparatus for adapting an acoustic touchscreen controller to the operating frequency requirements of a specific touchscreen are provided. The adaptive controller can either utilize look-up tables to achieve the desired output frequency or the it can use a multi-step process in which it first determines the frequency requirements of the touchscreen, and then adjusts the burst frequency characteristics, the receiver circuit center frequency, or both in accordance with the touchscreen requirements. In one embodiment, the adaptive controller compensates for global frequency mismatch errors. In this embodiment a digital multiplier is used to modify the output of a crystal reference oscillator. The reference oscillator output is used to control the frequency of the signal from the receiving transducers and/or to generate the desired frequency of the tone burst sent to the transmitting transducers. In another embodiment that is intended to compensate for both global and local frequency variations, the adaptive controller uses a digital signal processor. The digital signal processor, based on correction values contained in memory, defines a specific center frequency which preferably varies according to the signal delay, thus taking into account variations caused by localized variations in the acoustic wave reflective array. In yet another embodiment, a non-crystal local oscillator is used to provide the reference signal in the adaptive controller. The use of such an oscillator allows the controller to be miniaturized to a sufficient extent that it can be mounted directly to a touchscreen substrate. A feedback loop is used to compensate for oscillator drift. A discriminator circuit determines the degree of deviation from the desired frequency. The output from the discriminator is used to adjust the frequency of the local oscillator such that it tracks the frequency of the touchscreen.

摘要： A touch sensor having an acoustic substrate, an acoustic transducer, and an acoustically diffractive grating is provided. The grating is disposed between the transducer and the substrate, so that acoustic energy from the transducer is coupled to an acoustic wave propagating along the surface of the substrate. If used in a display device, the combination of the transducer and grating may provide a low profile that allows the assembly to be more easily placed between the acoustic substrate and a bezel placed in front of the substrate. No acoustic components need be mounted on the rear surface of the substrate, allowing the acoustic substrate to be formed on the front surface of the display device.

摘要： A system and method of orchestrating failover operations of servers providing services to an internal computer network includes a DR server configured to execute a control script that performs a failover operation. Information needed to perform the failover operation is stored on the DR server thereby eliminating the need to store agents on each of the application's primary and backup servers. The DR server may provide a centralized location for the maintenance and update of the failover procedures for the internal network's redundant services. A failover operation may be initiated by an authorized user in communication with the internal computer network.

摘要： A color display is disclosed that has on an inner display surface a periodic pattern of luminescent deposits having a smallest deposit-to-adjacent-deposit pitch "P-D". The display has on an outer surface glare reduction means in the form of an undulating periodic pattern of light-scattering elements whose smallest element-to-adjacent-element pitch "P-E" is significantly less than the pitch "P-D" to avoid moire effects, but significantly greater than the longest wavelength of visible light to minimize diffraction effects. The color display according to the invention may comprise a color cathode ray tube havbing a touch panel on its front surface.
