A control method for a user interface system may include receiving an input signal, receiving a temperature signal indicative of a temperature, generating a baseline signal based on at least one among the input signal and the temperature signal, calculating an error signal based on a difference of the input signal and the baseline signal, and modifying the baseline signal based on the error signal.

An apparatus for providing a switch mechanism comprises a housing and a pressure sensitive device mounted to the housing. An actuator is moveably connected to the housing to enable the actuator to move along an axis towards and away from the pressure sensitive device. A resilient member has a first end connected to the actuator and a second end connected to the pressure sensitive device.

An opening switch for a vehicle having a decorative cover assembly, a sensor housing region, and a microelectromechanical (MEMS) sensor mounted in the sensor housing region. The decorative cover assembly has an inner surface, an outer surface, an anchor portion, and a deflection portion. When contact from a vehicle user occurs at the deflection portion in the decorative cover assembly, a microdeflection occurs. The microdeflection has a microdeflection apex, and the microdeflection apex is spaced from other surfaces in the sensor housing region when the contact from the user occurs at the deflection portion in the decorative cover assembly. The MEMS sensor is configured to generate an output signal that is indicative of a force of the contact from the user. The force integrated switch can include haptic feedback and/or backlighting.

An electronic device according to an embodiment of the disclosure may include a housing, a key cover that penetrates at least a part of the housing and exposes at least a part of the key cover to an outside, a key button that is disposed inside the key cover and generates a pressing signal when the key button is pressed, a pressure sensor including a plurality of depressurization points between the key cover and the key button, and at least one processor electrically connected to the pressure sensor and the key button, and the at least one processor obtains a pressure signal corresponding to each of the plurality of depressurization points through the pressure sensor, obtains the pressing signal through the key button, and performs a specified operation based on the pressure signal corresponding to each of the obtained depressurization points and the pressing signal.

A programmable or configurable non-contact solid state switch device and method are provided for emulating a high reliability switch. The switch device senses position information related to a switch and is calibrated using a learning operation to learn position information of mechanical features of the switch and to map the positions of these features. Electrical outputs or functions are assigned to the mapped positions and stored such that the switch device generates the outputs when their corresponding positions are sensed. A switch device is uniquely configured to the mechanical system in which it operates.

An electronic device includes a rotation operation unit including a rotation operation member, and a finger placing portion configured so that a finger is placed on it when the electronic device is gripped. The rotation operation unit and the finger placing portion are located in close proximity to each other on a surface on a user side of the electronic device. The rotation operation unit is tilted with respect to the electronic device toward the finger placing portion.

A trim panel intended to be arranged within the interior of a vehicle cabin, the trim panel having an appearance face intended to be visible to an occupant of the cabin, a reverse face provided with an interface for attachment of the trim panel to a support member, and at least one attachment bracket forming part of the attachment interface. The appearance face defines a tactile interaction area intended to serve as a control input for the occupant, and at least one sensor assembly is arranged on an attachment bracket, each sensor assembly being adapted to, when the trim panel is arranged inside a cabin, detect a deformation of its attachment bracket upon pressure exerted by an occupant on the trim panel on the tactile interaction area.

The present inventors have recognized that an electrical switch for opening doors in buildings, calling elevators, and the like can be improved to require less physical contact, larger activation area, and multiple activation methods, with increased reliability, by utilizing a piezoelectric sensor specifically arranged between rigid, parallel mounting plates in which one of the plates (an inner plate) is rigidly fixed to prevent movement while the other plate (an outer plate) is accessible for receiving physical contact. By rigidly fixing the inner plate, such as by mounting to a wall or bollard, the sensor can react with sensitivity upon an application of less pressure on the outer plate. Such pressure compresses the sensor between the plates to produce an electrical signal. A controller receiving the signal can, in turn, execute to open a door, call an elevator and/or activate a light or sound to provide feedback.
