The motherboard has a first principal surface including a unit mount portion on which an electronic device unit is to be mounted, and the second principal surface parallel to the first principal surface, and is installed on the plate member.

A fastening device and fastening method for fastening a distribution box control panel to a distribution box, the fastening device comprising a push block, a biasing member, a shell, and a locking member sleeved in the shell, wherein the method utilizes the biasing force of the biasing member to fasten the device, and utilizes the elasticity of the locking member having a bending structure to realize assembly and disassembly, where a user can conveniently assemble the device with hand alone, i.e., during assembly, the fastening device is pushed in along a notch in the distribution box control panel and then pressed tightly, and during disassembly, the fastening device can be pushed out after the locking member is pressed such that in comparison to a screw fastening method, the fastening device of the present invention provides a constant fastening force, thus realizing more stable and reliable fastening.

Apparatuses for expansion device retention. Specifically, the disclosed apparatuses implement retention mechanisms capable of being temporarily fastened to expansion slots whereat expansion devices may be installed. By fastening to the expansion slots, any permanent redesign and/or modification to the printed circuit boards, whereon the expansion slots may be mounted, may be minimized (if not eliminated). Amongst the disclosed apparatuses, an attachable hockey stick is introduced for expansion devices lacking a hockey stick shaped feature, where the attachable hockey stick engages with the aforementioned retention mechanisms to secure the expansion devices during, for example, shock events.

A remote releasing module includes a bracket, a toggle button, and a moving member. The bracket includes a first end portion and a second end portion away from each other. The toggle button is pivotally connected to the first end portion of the bracket and includes a first driving portion. The moving member is movably disposed on the bracket and extends from a position close to the first end portion to the second end portion. The moving member includes a second driving portion disposed on the first driving portion so as to drive the toggle button to move. A circuit board device including a circuit board body, a connector slot, and the remote releasing module is also provided. The connector slot is disposed on the circuit board body.

A casing assembly is adapted for a carrier, the casing assembly includes a casing, an actuating component, and an engagement mechanism, the casing is adapted to be stacked on the carrier, the actuating component is disposed on the casing, the engagement mechanism includes a first component and a second component, the first component and the second component are connected to each other and are movably disposed on a surface of the casing, the actuating component is removably engaged with an end of the first component located away from the second component so as to cause the second component to be removably engaged with a first post of the carrier by pushing the first component.

An electronic device for an aircraft includes: a casing; a first boss projecting from a bottom wall of the casing toward an opening of the casing; a second boss projecting from the bottom wall of the casing toward the opening of the casing by a larger amount than the first boss; a first circuit board fixed to the first boss; and a second circuit board fixed to the second boss. The first circuit board includes cutouts penetrated by the second boss when the first circuit board is fixed to the first boss.

Described herein is a sensor device. The sensor device comprises a housing and a printed circuit board encased by the housing. The printed circuit board comprises an image sensor that captures image data, an image sensor processor that processes the image data, a serializer that converts one or more data channels associated with the image data into a single data channel, and one or more exposed surfaces. The one or more exposed surfaces dissipate heat generated by the image sensor, the image sensor processor, and the serializer from the printed circuit board to the housing.

This document describes an access point device and associated systems and methods. The techniques and systems include an access point device that includes a housing with an antenna carrier, a circuit board assembly, a heat sink, and a heat shield positioned within the housing. The housing includes a top housing member connected to a bottom housing member. The top housing member includes a concave-down top-end portion connected to a generally cylindrical vertical wall via rounded corners. The antenna carrier supports multiple antennas positioned proximate to an inner surface of the vertical wall. The heat sink is positioned between the antenna carrier and the circuit board assembly. The circuit board assembly is positioned between the heat shield and the heat sink, and the heat shield is positioned between the circuit board assembly and the bottom housing member.
