Abstract: An optical distance-measuring device includes: a light emitter having plural light-emitting areas that are arrayed in a first direction; an optical system provided at a position toward which the light emitter emits light, the optical system causing light beams respectively emitted from the plural light-emitting areas to be deflected in respectively different directions; and a detector including plural detecting elements configured to detect a reflection of light outgoing from the optical system. Detecting directions of some of the plural detecting elements are different from detecting directions of others of the plural detecting elements in the first direction.

Abstract: A biological information measurement apparatus includes a processor configured to: if a predetermined number of plural measurements of an oxygen circulation time are to be performed, before a predetermined oxygen-circulation-time measurement period ends during a first measurement of the oxygen circulation time, notify a test subject of a breath-hold instruction as a preparation for a second measurement of the oxygen circulation time, the test subject being a person for whom the oxygen circulation time is measured, the second measurement being a subsequent measurement to the first measurement.

Abstract: A light emitting device includes a wiring board having a first wiring layer and a second wiring layer adjacent to the first wiring layer via an insulating layer, and a laser having a cathode electrode and an anode electrode, mounted on the wiring board, and driven through low-side driving. The first wiring layer includes a cathode wire connected to the cathode electrode, an anode wire connected to the anode electrode, and a first reference potential wire connected to a reference potential. The second wiring layer includes a second reference potential wire connected to the reference potential. An area of an overlap between the second reference potential wire and the anode wire is larger than an area of an overlap between the second reference potential wire and the first reference potential wire.
