An exemplary inventive freeboard detection system includes a tubular watertight temperature-sensing device and a computer. The temperature-sensing device includes a printed circuit board assembly (PCBA), a potting compound, and a hollow rigid tube. Inside the tube the potting compound encapsulates the PCBA, which includes a printed circuit board (PCB) and multiple temperature sensors closely and equidistantly arrayed along the length of the tube. The temperature-sensing device is vertically secured in a partially submerged state to a vessel with the expectation that some of the vertically arrayed temperature sensors will sense air temperature and others will sense water temperature. On an ongoing basis, the computer receives signals from the temperature sensors and processes the signals to monitor freeboard values, which the computer calculates based on differences in temperature measurements corresponding to pairs of consecutive (and/or nonconsecutive) temperature sensors. A maximum calculated difference in temperature measurements is indicative of the location of the water surface.

A proximity sensor in which generation of voids in a resin sealing portion sealing an inside of a housing can be suppressed and thus a yield is improved. The proximity sensor includes a housing, a detection coil, a circuit board and a resin sealing portion. The circuit board is accommodated in the housing to partition an internal space of the housing, and the resin sealing portion covers at least a part of the circuit board by filling the internal space of the housing and thus seals a covered portion of the circuit board. A resin injection port configured to inject a liquid resin forming the resin sealing portion by curing the liquid resin is provided in the housing, and a cutout portion having a notch shape or an opening shape is provided in the circuit board to include at least a part of a portion facing the resin injection port.

In a relay connector, a male terminal is formed in a rod-like shape, inserted into a through hole penetrating a male terminal housing chamber, extends inside a cylinder part, and has a first contact part. A protective plate includes a body part that partitions an internal space defined by the cylinder part and the male terminal housing chamber into a first space portion located on the first contact part side of the male terminal and a second space portion located on the male terminal housing chamber side of the male terminal, a terminal hole that is formed in the body part, and configured to receive the male terminal thereinto, and a filling port that is formed in the body part, and communicably connects the first space portion and the second space portion to each other. The second space portion is filled with a potting filling part.

The implantable sensor assembly also includes one or more electronic components disposed within the cavity of the housing and one or more probes disposed on the exterior surface of the substrate layer and electrically coupled to the one or more electronic components by one or more electrical connections extending through the housing.

A printed circuit board assembly for a field bus device is described, comprising a housing, a printed circuit board, and at least one electronic component fastened to the printed circuit board. The printed circuit board is arranged in the housing. The housing has at least one bearing surface on which a gap filler is arranged, against which the electronic component rests so that the printed circuit board is mounted in the housing via the electronic component and the gap filler. A potting compound is provided, which covers the printed circuit board and contacts the gap filler.

Potted electronic assemblies are disclosed along with methods of making and cooling them. The electronic assemblies include a conductive heat transfer medium disposed between and in contact with an electronic component and a heat sink. The conductive heat transfer medium has a hardened fluid polymer material that includes boron nitride nanotubes dispersed therein.
