Abstract: A ceiling mount comprises a mounting plate assembly that is configured to be coupled to the electronic device. The ceiling mount further includes two clips configured to engage with opposite sides of a ceiling rail to mount the ceiling mount to the ceiling rail, and two linkages configured to be extendible and collapsible. Further, each of the clips includes an engagement member configured to engage the ceiling rail, and a supporting arm coupled to the engagement member. The mounting plate assembly is positioned between the clips and the linkages. Moreover, each of the two linkages is connected to each of the two clips so that moving the two clips relative to the mounting plate assembly moves, in turn, the two linkages relative to the mounting plate assembly. The movement of the two linkages relative to the mounting plate assembly maintains the two clips parallel to each other.

Abstract: Implementations of the present disclosure relate to radio frequency (RF) connection. In the implementations, an access point (AP) comprises an antenna module, a separation plate, a main board, and a connector. The antenna module is fixed on the first surface of the separation plate. The connector comprises an inner conductor and an outer conductor passing through a hole in the separation plate and connects the trace of the antenna module with the electronic components in the main board. The inner conductor and the outer conductor are retractable along a direction perpendicular to the main board. In this way, by directly connecting the antenna with the main board by a retractable connector, additional cables can be spared without sacrificing the mechanical performance of the connection structure.

Abstract: A ceiling mount comprises a mounting plate to be coupled to an electronic device and two clips to be mounted to a ceiling rail. The clips comprise engagement members to engage with opposite sides of the ceiling rail, respectively, and support arms movably coupling the engagement members to the mounting plate. One of the support arms of each clip comprises linear gear teeth. The ceiling mount also comprises a circular gear coupled to the mounting plate and engaged with the respective linear gear teeth of the clips, and a pawl engaged with the circular gear and movable between a first state and a second state. In the first state of the pawl, the engagement members can be moved toward one another and are prevented from being moved away from one another, and in the second state of the pawl, the engagement members can be moved away from one another.

Abstract: A removable electronic module including electronic circuitry and a universal serial bus (USB) plug. The USB plug has an inner body and an outer sleeve movably coupled to the inner body. The outer sleeve is movable between a first position and a second position relative to the inner body. The inner body includes electrical contacts and one or more protrusions. The outer sleeve has one or more spring latch members configured to engage with a USB port in an installed state with a USB port. The protrusions are configured to, when the outer sleeve is in the first position, prevent removal of the USB plug from the USB port by preventing the spring latch members from disengaging from the USB port. When the outer sleeve is in the second position the spring latch members are free to disengage and the USB plug may be removed from the USB port.
