Abstract: An acoustic touch apparatus is provided that includes a substrate capable of propagating surface acoustic waves, such as Rayleigh-type or Love-type waves. The substrate has a front surface, a back surface, and a curved connecting surface formed between the front surface and the back surface. The apparatus also includes at least one acoustic wave transducer and at least one reflective array, the acoustic wave transducer and the reflective array behind the back surface of the substrate. The acoustic wave transducer is capable of transmitting or receiving surface acoustic waves to or from the reflective array. The reflective array is capable of acoustically coupling the surface acoustic waves to propagate from the back surface and across the front surface via the curved connecting surface. Various types of acoustic touch apparatus with edge sensitive touch functions can be provided, according to specific embodiments.

Abstract: A touchscreen system is provided that incorporates a simplified sealing system around the bezel. The touchscreen system includes a planar touchscreen coupled to a display device having a planar display surface, the touchscreen having a touch sensitive region on a touchscreen surface. A frame is positioned above the touchscreen. The frame includes a central opening that substantially provides an outer border for the touch sensitive region, a rigid portion comprising an outer periphery of the frame, a flexible resilient portion connected to the rigid portion, the flexible portion comprising an inner periphery of the frame, and a sealing portion interposed between the touchscreen surface and the flexible portion. The flexible portion of the frame is directed out of a plane defined by the rigid portion toward the touchscreen prior to bringing the frame into contact with the touchscreen.

Abstract: An apparatus for sealing the end of an elongate cable such as a heating cable includes (1) a housing with a first open end and a second open end and a strain relief element positioned within the housing, (2) a flexible container which can be positioned over the cable end and (i) is of generally tubular shape, (ii) has an interior surface and an exterior surface, (iii) has a first open end and a second closed end, and (iv) contains a sealant; and (3) a cap which can be mated with the housing at the second open end, and cover the flexible container. The apparatus has excellent moisture-resistant properties even after repeated exposure to high temperatures, is reenterable, and can be readily mounted on a substrate such as a pipe.
