A system for remotely monitoring a depletion state of a sacrificial anode. The system includes a light emitter that is configured to emit a light beam and an optical receiver positioned to receive the light beam. A sacrificial anode is located between the light emitter and the optical receiver in a pathway of the light beam, the sacrificial anode being electrically coupled to a metallic structure for the purpose of minimizing corrosion of the metallic structure. Absent a presence of the sacrificial anode in the pathway of the light beam, the optical receiver is configured to receive the light beam, and in response to receiving the light beam, to generate an electrical signal indicative of the depletion state of the sacrificial anode.

An electronic apparatus includes, in a case, substrates with electronic components mounted thereon, a thermoplastic hot-melt resin, and a fluid branch member, wherein: the inside of the case is divided into a plurality of spaces; the plurality of spaces are at least any space among spaces between the case and the substrates and spaces between the substrates, and are filled with the thermoplastic hot-melt resin; and the fluid branch member is provided with an opening as an inlet for the thermoplastic hot-melt resin, and flow path parts for branching the thermoplastic hot-melt resin into multiple parts and guiding the same.

An optical module includes a beam-tilting light source enclosure. The enclosure is coupled to a substrate that includes a light emitter connected thereto. The enclosure has a geometry such that the enclosure has a first surface configured to couple substantially flat to the substrate and a second surface tilted with respect to the first surface and configured to couple substantially flat to a component of an electronic device through which the light is to project. The enclosure is optically transmissive and covers the light source when coupled to the substrate. In this way, the enclosure may be assembled and used in the electronic device by coupling the first surface to the substrate and coupling the second surface to the component.
