Knob on display (KoD) devices and related systems, methods, and devices are disclosed. A KoD device includes a touch surface including a conductive material. The touch surface is configured to be positioned in a released position and in a depressed position. The touch surface is configured to be positioned in the depressed position responsive to pressure applied to the touch surface. The KoD device also includes a push electrode pad configured to be positioned in engagement proximity to a touch sensor of a touch screen device in both the released position and the depressed position. The push electrode pad is electrically connected to the conductive material of the touch surface responsive to the depressed position and electrically isolated from the conductive material of the touch surface in the released position.

An operating device includes a first operating element with which a user can select one or numerous main functions of a vehicle and that can rotate about an axis of rotation and has at least one predefined fixed rotational position. A second operating element with which a user can adjust subfunctions of the main function can rotate about the axis of rotation and also comprises an actuator unit that comprises a magnetorheological medium configured to exert a retaining force on the second operating element based on a viscosity of the magnetorheological medium. The actuator unit is configured to set the viscosity on the basis of the main function selected with the first operating element, and on the basis of a rotational position of the second operating element.

An input device includes: a first electrode; a support body that supports the first electrode; a fixed body fixed above the support body; a second electrode; a movable body that holds the second electrode in a state where the second electrode faces the first electrode with a predetermined space being provided therebetween, and causes the second electrode to approach and recede from the first electrode in a movement direction by rotating; an operation body that is fixed movably relative to the fixed body in a state where the operation body is engaged with the movable body, and causes, by being operated by a user, the movable body to rotate; and a biasing part that is disposed between the movable body and the fixed body, and applies, to the movable body, a biasing force toward the support body.

Disclosed herein is a leakage protector, which includes a housing. A base plate and a brush are arranged in the housing. A first conducting strip and a second conducting strip spaced apart are arranged on the base plate. The brush is provided with contact pins to contact the first conducting strip and the second conducting strip, respectively. The second conducting strip can generate different analog voltages, and the first conducting strip is configured to transmit different analog voltages to a microprocessor. A user can drive the brush to move through an actuating part, and set the power-on time of the leakage protector in one step.

An apparatus for carrying out inputs in an input capturing unit that can be coupled to the apparatus. An operating device has a receiving part and an operating element that is rotatably mounted on the receiving part. The operating element can be rotated by a finger to effect an input. A torque for the rotation of the control element can be adjusted by way of a controllable braking device. In addition, the control element has at least two actuating zones. The resistance to movement for the movability of the operating element can be adjusted depending on from which actuation zone the operating element is actuated and/or which actuation zone was previously activated.

In one example, a rotary knob switch includes: a knob head; a fixing mount disposed below the knob head and configured to allow at least a portion of the bottom of the knob head to pass through it; cam located at the bottom of the fixing mount and to be mated with the bottom of the knob head, a side of the cam forming at least one protruding control curved surface; and a slider, said slider being coaxial with the cam, ramp with different heights being provided along edge of the slider, wherein, when the cam rotates, the control curved surface of the cam presses the ramp of the slider, such that the slider slides along axial direction towards the bottom of the rotary knob switch, the knob head comprises an indicator block, the lower part of the indicator block is provided with an axial light guide column.

A sleeve or case for a mobile device, such as a smartphone or tablet or other types of hand-held device or mobile smart device, has a sleeve part for at least partially enclosing the mobile device and an input device arranged in the sleeve part for controlling the mobile device which can be received in the sleeve part. The input device includes a movable control element and a magnetorheological brake. Any movement of the control element can be selectively damped by way of the magnetorheological brake.

An input device includes: a first electrode; a support body that supports the first electrode; a fixed body fixed above the support body; a second electrode; a movable body that holds the second electrode in a state where the second electrode faces the first electrode with a predetermined space being provided therebetween, and causes the second electrode to approach and recede from the first electrode in a movement direction by rotating; an operation body that is fixed movably relative to the fixed body in a state where the operation body is engaged with the movable body, and causes, by being operated by a user, the movable body to rotate; and a biasing part that is disposed between the movable body and the fixed body, and applies, to the movable body, a biasing force toward the support body.

An operator control device for a vehicle may have a rotatable base body, an electronic unit, and a rotary unit. The rotatable base body may have a first operator control section for setting at least one first vehicle function which is assigned to the first operator control section, and a second operator control section for setting at least one second vehicle function which is assigned to the second operator control section. The electronic unit may be designed to make available a first contact signal which represents manual contact with or approaching of the first operator control section, and a second contact signal which represents manual contact with or approaching of the second operator control section. The rotary unit may permit a rotational movement of the base body.

The invention is a high temperature control knob that is installed on the power control knob stem of an existing appliance to prevent a material being heated from reaching a predetermined maximum temperature (e.g., the burning point temperature for oil), and thereby preventing an undesired event (e.g., a fire). The high temperature control knob comprises an alignment means having at least one stop that is adjustable about a set of temperature markings containing the predetermined maximum temperature, and may further comprise a dial with an arm that mounts of the power control knob stem. The at least one stop may be aligned to the predetermined maximum temperature by rotating the alignment means about the power control knob stem and tightening a fixing means to hold the alignment means in place. The arm of the dial contacts the at least one stop preventing the appliance from exceeding the predetermined maximum temperature.
