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. Signals from the force sensors are processed to determine a magnitude, acceleration, and/or location of the force input, and a haptic feedback response is received by the touch overlay plate. The haptic feedback response is based on the force magnitude, acceleration, and/or location of input, according to some implementations. Axially arranging the PCBs reduces the footprint of the switch assembly and allows for the inclusion of more electrical components in the switch assembly, according to some implementations.

Abstract: A haptic communication system includes either a switch assembly or a compilation of discretely installed components. The switch assembly and the installed components utilize a haptic actuator to elicit tactile and/or audibly perceptible haptic outputs. The switch assembly and/or a collective haptic communication system includes a processor communicating with the actuator. Computerized instructions cause the processor to receive a message from an external system, identify either an audio or vibrational output signal, and communicate the output signal to the actuator. The audio or vibrational output signal causes the actuator to propagate a respective pressure wave that elicits an audible or inaudible, vibrational response at the output surface of the actuator. The pressure wave causes tactilely and/or audibly perceptible vibration within the individual switch assembly or within an overall installation such as a seat or steering assembly in a vehicle.

Abstract: Implementations include methods of controlling a haptic response comprising receiving a force signal from a force sensor; determining a force magnitude associated with the force signal; comparing the force magnitude with an initial threshold force amount to determine whether the force magnitude exceeds the initial threshold force amount; measuring an elapsed time that the force magnitude exceeds the initial threshold force amount; comparing the elapsed time to a minimum elapsed time; if the elapsed time being greater than the minimum elapsed time, generating a haptic feedback control signal, the haptic feedback control signal causing a haptic actuator to propagate a plurality of pressure waves at a propagation frequency, the propagation frequency being proportional to the force magnitude; and generating a scroll control signal that causes a menu system to scroll through a plurality of menu options provided by the menu system at a scroll frequency associated with the propagation frequency.
