Abstract:
A method comprising: patterning one or more electrical layers on a substrate (205); shaping the patterned substrate (205) into a 3-dimensional contour, wherein the contour including a significant change in gradient in or adjacent to one or more sensing areas of the electrical layer-, and over-moulding the shaped substrate (205), wherein degradation of a trace (509) in the electrical layer at or adjacent to the one or more sensing areas during shaping and/or over-moulding is substantially minimised based on the width of the trace (509), the thickness or number of layers of the trace (509), the bending radius of the trace (509), the material of the trace (509), and/or a primer over layer on the trace (509).
Abstract:
The invention relates to a sensor arrangement (19a, 19b, 19c) for detection of proximity and/or touching. It comprises at least one sensor supporting surface (7) having a first flat face (7') and a second flat face (7"), a proximity and/or touching sensor (9) which is connected to the first flat face (7') and/or to the second flat face (7") of the sensor supporting surface (7), a decoration supporting medium (1a, 1b, 1c) with a first support flat face (1') and a second support flat face (1"), a decoration layer (3) which is connected to the first support flat face (1') and/or to the second support flat face (1") of the decoration supporting medium (1a, 1b, 1c), and/or is an integral component of the decoration supporting medium (1a, 1b, 1c). In this case, the sensor supporting surface (7) and the decoration supporting medium (1a, 1b, 1c) are connected to one another such that a connection along their mutually facing flat face (7') and support flat face (1") is not formed, or is partially formed. Furthermore, the invention relates to a kit and to a production method for a sensor arrangement (19a, 19b, 19c) such as this.

Abstract:
A display assembly includes a transparent cover piece (62), a display shroud (48; 248) having a contact structure (74; 274) arranged to face the transparent cover piece (62), an interface subassembly (32; 232) mounted on the display shroud (48; 248), an electronics board shroud (44) having a support member (82) and a connection feature (84), and a biasing member (46) operably engaged between the display shroud (48; 248) and the electronics board shroud (44). The connection feature (84) mechanically connects the electronics board shroud (44) to the display shroud (48; 248) while permitting axial displacement and rotation therebetween. The biasing member (46) rests on the support member (82) of the electronics board shroud (44), and the biasing member (46) is configured to urge the contact structure (74; 274) of the display shroud (48; 248) into physical contact with the transparent cover piece (62). The interface subassembly (32; 232) includes a display circuit (36) for providing a digital display and a touch circuit (34) for providing touch actuation at or near the digital display through the transparent cover piece (62).
