A load control device may be used to control and deliver power to an electrical load. The load control device may comprise a control circuit for controlling the power delivered to the electrical load. The load control device may comprise multiple actuators, where each of the actuators is connected between a terminal of the control circuit and a current regulating device. The number of the actuators may be greater than the number of the terminals. The control circuit may measure signals at the terminals and determine a state configuration for the actuators based on the measured signals. The control circuit may compare the state configuration to a predetermined dataset to detect a ghosting condition.

A motion-enable device includes a mechanical switch and a capacitive sensor with a sensing region that is located adjacent to the mechanical switch. The mechanical switch enables a first signal when closed or actuated that indicates that the mechanical switch is in an active state. The capacitive sensor enables a second signal when a conductive object is disposed in the sensing region, where the second signal indicates that the capacitive sensor is in an active state. Enablement of operation of an apparatus depends on receipt of both the first signal and the second signal. The mechanical switch and the capacitive sensor act as the two separate switches required by functional safety requirements for a motion enable device. Because the sensing region of the capacitive sensor is adjacent to the mechanical switch, the first and second signals are generated when an operator actuates the mechanical switch with a single digit.

A device includes an engaging portion, a controller component, and a plurality of actuators. The engaging portion is configured to mechanically engage with at least one switch assembly. The plurality of actuators are capable of being actuated by the switch assembl(ies) when it/they are engaged with the engaging portion and depressed. The controller is configured to detect a first pattern of the plurality of actuators actuated at a time and responsively recognize a first type of switch assembly. The controller is also configured to detect a second (different) pattern of the plurality of actuators actuated at a time and responsively recognize a second (different) type of switch assembly.

A data execution device includes an input module including a single selection unit having three different selection locations at which selection is performed via a finger, i.e., a selection means, and a sensor unit having sensors generating signals in response to the selection; wherein the input module is provided to include three contact locations under the selection unit, located under the selection locations, and at least three sensors of the sensor unit spaced apart from the contact locations, respectively, by a predetermined distance, the selection locations are located within a range corresponding to the fingerprint region of a single thumb, and a separation distance formed under the center of the selection unit is configured to be shorter than a separation distance formed under each of the one side and other side of the selection unit.

Example methods and apparatuses of controlling a user interface with a plurality of input mechanisms are disclosed. One example method includes causing a first set of input mechanisms in the plurality of input mechanisms to be visually emphasized via a first visual technique while a second set of input mechanisms in the plurality of input mechanisms is not visually emphasized via the first visual technique, receiving a user input via an input mechanism that is included in the first set, based on the user input, determining a third set of input mechanisms in the plurality of input mechanisms and a fourth set of input mechanisms in the plurality of input mechanisms, and causing the third set of input mechanisms to be visually emphasized via the first visual technique while the fourth set of available input mechanisms is not visually emphasized via the first visual technique.
