摘要： A proximity sensor includes one or more detection electrodes to be capacitively coupled to an object, a contact electrode contactable with the object, an excitation circuit connected to one of the one or more detection electrodes or the contact electrode to supply an excitation voltage to the electrode to which the excitation circuit is connected, and a detection circuit connected to the other of the one or more detection electrodes or the contact electrode to generate, based on a detection voltage at the electrode connected to the detection circuit, a detection signal in response to an electrostatic capacitance between the one of the one or more detection electrodes and the object. The detection circuit generates the detection signal in response to the electrostatic capacitance. The detection signal indicates a proximity of the object in contact with the contact electrode to the one of the one or more detection electrodes.

摘要： A tactile and proximity sensor includes a light source, a light receiving section, and a cover. The light source emits light. The light receiving section receives light and generates a signal providing a result of the received light. The cover includes an elastic body that deforms under external force and that covers the light source and the light receiving section. The cover includes a reflective section that reflects light between the light source and the light receiving section and a transmission section that allows light to pass through in a first direction from the light source and that allows light to pass through in a second direction from the light receiving section.

摘要： A user interface device includes a grip including dimensions in a radial direction and a circumferential direction and extending in a longitudinal direction, and at least one optical sensor provided at the grip including a proximity sensor that includes a light emitter and a light receiver, and a force sensor to detect a contact force by an object. The proximity sensor emits light from the light emitter to a predetermined detection range around the force sensor, and detects when the object is in proximity to the force sensor according to a light reception result obtained by light incident from the detection range to be received by the light receiver. The detection range is biased to one side in the circumferential direction from a position of the force sensor toward an outer side portion in the radial direction, and is wider in the circumferential direction than in the longitudinal direction.

摘要： A tactile and proximity sensor includes a light source, a light receiver, an elastic structure, and a reflecting mirror. The light source emits light. The light receiver receives light and generates a signal indicating a result of reception of the light. The elastic structure includes an elastic body deformable in response to an external force and includes a reflecting portion to reflect light and transmitting portions to transmit light. The reflecting mirror faces the light source to guide the light from the light source to the reflecting portion and the transmitting portion.

摘要： A cathode electrode, cathode pad electrodes, cathode wiring electrodes, an anode electrode, an anode pad electrode, and an anode wiring electrode are disposed on the surface of a vertical-cavity surface-emitting laser device. A light-emitting-region multilayer portion having active layers sandwiched by clad layers and DBR layers is formed directly below the anode electrode. A region where the light-emitting-region multilayer portion is formed serves as a light-emitting region. The light-emitting region is positioned closer to one end of the first direction than is a suction region onto which a flat collet sucks with respect to the first direction, in such a way that the light-emitting region is substantially in contact with or spaced a predetermined distance from the suction region.

摘要： A vertical cavity surface emitting laser includes an active layer that includes a quantum well, a first cladding layer and a second cladding layer between which the active layer is interposed. A first multilayer reflector layer is arranged on a side of the first cladding layer opposite to that on which the active layer is arranged. A second multilayer reflector layer is arranged on a side of the second cladding layer opposite to that on which the active layer is arranged. At least one of the first cladding layer and the second cladding layer includes a low activity energy layer having a band gap that is smaller than a smallest band gap of an optical confinement layer for forming the quantum well of the active layer and larger than a band gap of the quantum well.
