Abstract: An electronic device includes an outer case, a circuit substrate, a thermopile sensor chip, a filter structure, and a waterproof structure. The outer case has an opening. The circuit substrate is disposed inside the outer case. The thermopile sensor chip is disposed on the circuit substrate. The filter structure is disposed above the thermopile sensor chip. The waterproof structure is surroundingly connected between the filter structure and the outer case, wherein the waterproof structure has a through hole for exposing the filter structure and communicated with the opening of the outer case.

Abstract: A sensor device includes a passive infrared sensor, a control circuit, and a lens that directs infrared radiation onto the passive infrared sensor. The lens includes an obstruction that asymmetrically blocks transmission of infrared radiation through the lens. The control circuit is configured to determine the direction of crossing of individuals passing in front of the sensor device based on sensor signals from the passive infrared sensor.

Abstract: A thermal imaging apparatus comprising: a housing with a front wall having a first aperture extending therethrough, a rear wall spaced from the front wall, side walls connecting the front and rear walls; a thermal imaging camera mounted within the internal chamber of the housing, a camera lens aligned with the first aperture; and a fluid injection portion connected to the internal chamber that directs fluid towards the lens to clean the lens. Alternatively the housing defines first and second internal chambers spaced along a longitudinal axis of the apparatus separated by an internal wall comprising a second aperture extending therethrough; where the thermal imaging camera is mounted within the second internal chamber, with the camera lens aligned with the two apertures. Gas and fluid injection portions are connected to the first internal chamber to direct gas into the first chamber; and fluid towards the lens to clean the lens.

Abstract: A configuration that enables easy implementation of wiping disinfection for a gripping handle for which an operating means is provided. The gripping handle, which is grasped by an operator, is formed as part of the lower case including part of the housing. The gripping handle is provided with an operating surface portion that the operator touches when initiating the reading process. There is a site on the inner side of the gripping handle, wherein the site is opposed to the operating surface portion. At this site on the inner surface side, a detector is provided to detect the state in which the operating surface portion is touched.
