Abstract: Various implementations include a switch assembly that includes a housing and at least two printed circuit boards (PCBs) that are disposed within the housing and are axially arranged relative to each other. One or more force sensors are disposed on one of the PCBs, and, in some implementations, the one or more force sensors receive force input received by a touch overlay plate.

Abstract: A power circuit breaker has a housing defining a first passage and a cross passage through the housing. A bus bar extends through the cross passage and is configured to transmit electric power and/or break transmission of the electric power through the housing. The bus bar includes at least an input section, a coin or center section, and an output section that are separable from each other. The housing aligns a solenoid piston within the first passage of the housing. The solenoid has a piston with two opposite ends, and one of the ends operates as a plunger to separate the sections of the bus bar when the solenoid is actuated. The plunger moves the coin or center section of the bus bar out of contact with the input section and the output section of the bus bar to break electrical transmission across the bus bar.

Abstract: An illuminated substrate according to various implementations comprises a first surface and a second surface. The illuminated substrate defines perforations. A light diffusing layer is coupled to the first surface and overlays the perforations. A light source is disposed adjacent the second surface and emits light into the perforations. The light travels through the perforations from the second surface to and out of the first surface. The light then travels through the light diffusing layer. The perforations are arranged in a shape of an icon, and a shape of the light diffusing layer mimics the shape of the icon and ensures the light is evenly diffused. A coating is applied to the first surface and the light diffusing layer to provide protection, a smooth texture, a consistent appearance, and/or surface features.

Abstract: Systems and methods of printing sensor loops on a sensor mat for use in a steering wheel are disclosed herein. For example, the sensor mat may include a base substrate, one or more printed sensing loops, and an insulating material. The printed sensing loops are made with conductive ink that is disposed upon the base substrate or the insulating layer from a print head and adheres thereto. These sensor mats are versatile with respect to the type of base substrate and insulating materials that may be used, the shape of the sensing loops, and the area each loop may occupy. Shielding loop(s) may also be printed adjacent the sensing loop(s). This configuration allows shielding for the sensing loops as part of the sensing mat, which may reduce the thickness of the steering wheel rim and manufacturing and installation times.

Abstract: In a touch screen environment, a computer calculates an effective position and updated effective positions of simultaneous or sequential touch events by calculating average coordinates of the touch events using force measurements. The average coordinates correspond to computerized maps of the user interface and z coordinates correspond to an average force at the x and y locations. The effective positions are used to determine if the user's touches move across multiple virtual input areas having priority and non-priority relationships. By expanding a virtual input area of the map for those areas having a priority label relative to a different non-priority virtual input area, the computer effectuates appropriate functions depending on where the most recent effective position lies.
