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 method and apparatus for discriminating against false touches in a touchscreen system is provided. The system is designed to confirm a touch registered by one touch sensor with another touch sensor, preferably of a different sensor type, prior to acting upon the touch (i.e., sending touch coordinates to the operating system). If the touch registered by the first touch sensor is not confirmed by the second touch sensor, the touch is invalidated. Thus the strengths of one type of sensor are used to overcome the deficiencies of another type of sensor. In one aspect, the secondary touch sensor comprises a force sensor to discriminate between true and false touches on other types of touch sensors, such as contaminants on optical and surface acoustic wave sensors, noise or weak signals on capacitive sensors, etc. The force sensor may be a simple one-element system that merely indicates that a touch has occurred or a multi-element system that can provide confirming or supplementary coordinate data. In another aspect, a capacitive sensor is used to confirm or veto touch data from optical, surface acoustic wave, and force sensors. As is the case with the secondary force sensor, a secondary capacitive sensor may be a simple discrete type or capable of providing touch coordinates in its own right. In a specific embodiment, one in which no touch overlay is used on a CRT monitor, the secondary touch sensor may employ the resistive coating on the surface of the CRT in combination with a current monitoring circuit that measures the amplitude of the electromagnetic noise signal coupled to the resistive coating. In this application when the screen is touched by a grounded object, the detected signal amplitude change exceeds a preset threshold thus indicating a valid touch.
摘要翻译：提供了一种用于区分触摸屏系统中的假触摸的方法和装置。该系统被设计为在触摸之前（即，向操作系统发送触摸坐标），确认由一个触摸传感器与另一个触摸传感器（最好是不同的传感器类型）登记的触摸。如果第一触摸传感器登录的触摸未被第二触摸传感器确认，则触摸无效。因此，使用一种类型的传感器的优点来克服另一种传感器的缺陷。在一个方面，二次触摸传感器包括力传感器，以区分其他类型的触摸传感器的真实和错误触摸，例如光学和表面声波传感器上的污染物，电容传感器上的噪声或弱信号等。力传感器可以是仅仅表示触摸已经发生的简单的单元件系统或者可以提供确认或辅助坐标数据的多元件系统。另一方面，电容传感器用于确认或否决来自光学，表面声波和力传感器的触摸数据。与次级力传感器的情况一样，次级电容式传感器可以是简单的离散型或能够自己提供触摸坐标。在具体实施例中，在CRT监视器上没有使用触摸覆盖的实施例中，辅助触摸传感器可以与电流监视电路结合使用CRT表面上的电阻涂层，该电流监测电路测量耦合的电磁噪声信号的幅度到电阻涂层。在本应用中，当屏幕被接地物体触摸时，检测到的信号幅度变化超过预设的阈值，从而指示有效触摸。

The system is designed to confirm a touch registered by one touch sensor with another touch sensor, preferably of a different sensor type, prior to acting upon the touch (i.e., sending touch coordinates to the operating system). If the touch registered by the first touch sensor is not confirmed by the second touch sensor, the touch is invalidated. Thus the strengths of one type of sensor are used to overcome the deficiencies of another type of sensor. This system is particularly well suited to meet the demands of an outdoor or semi-outdoor application. In one embodiment, one or more force sensors are used as the false touch sensor and a projective-capacitive sensor is used as the position coordinate determining sensor. In another embodiment, a projective-capacitive sensor is used as the false touch sensor. As the projective-capacitive sensor is only being used to provide touch confirmation, in this embodiment very few electrodes are required as well as minimal channel electronics. In another embodiment, both touch sensors are capable of providing accurate touch coordinates. In this configuration the system preferably determines which of the sensors is more likely to provide accurate information based on the circumstances.

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 touch sensor, having an acoustic wave transmissive medium having a surface and a touch sensitive portion of the surface, a transducer system for emitting acoustic energy into the medium, and a receiver system for receiving the acoustic energy from the substrate as at least two distinct sets of waves, a portion of each of which overlap temporally at the receiver system or overlap physically by propagating in the touch sensitive portion along axes which are substantially non-orthogonal, the receiver system determining a position or a waveform perturbing characteristic of a touch on the touch sensitive portion. The receiver may be an amplitude detector or be sensitive to a phase-amplitude characteristic of the received acoustic waves.
