The waterproof stability can be effectively guaranteed through the external part hard rubber frame and the internal part hard rubber frame.

The two-way communication system comprises a non-invasive and non-implanted system which remains completely invisible to an outside observer when in use by an operator or user and allows for clear two-way communications. This system is generally comprised of a mouthpiece component, relay component, infrastructure communication device, and an optional system control which may interface with the relay component.

A waterproof mechanism includes a telescopic member; a thrusting member; and a sleeve. The telescopic member includes a retractable telescopic base, and an opening provided on an upper end of the telescopic base. The thrusting member includes a head portion and a rod portion having an outer diameter smaller than that of the head portion. The sleeve includes a cavity penetrating through both ends of the sleeve. The sleeve is sleeved on the rod portion of the thrusting member, a part of the thrusting member and a part of the sleeve are inserted into the opening of the telescopic base. The head portion of the thrusting member is held between the telescopic base and the sleeve, and an inner wall surface of an upper portion of the opening of the telescopic base and an outer wall surface of a lower portion of the sleeve are in a waterproof connection.

The present disclosure provides an underground base station configured to locate below a ground surface of the earth. It includes an outer shell assembly, configured to have a cavity therein; a sealing assembly, arranged to be housed within the cavity and provided with at least one communication component therein; a fiber assembly, disposed to fix onto the outer shell assembly and a fiber from which is connected with the at least one communication component; and a cover assembly, fixed on top of the outer shell assembly and having an antenna module therein. The sealing assembly is configured to have at least one opening facing away from the ground surface.

Casing assemblies and a mobile terminal are provided. A casing assembly includes: a rear casing and a wearproof assembly. The rear casing includes an outer surface and an inner surface opposite the outer surface, and the rear casing defines a mounting hole through the outer surface and the inner surface. The wearproof assembly includes a coupling member and a decorative member. The coupling member is coupled to the rear casing passing through the mounting hole, and defines a recess at a side of the coupling member opposite the inner surface. The decorative member is embedded in the recess. The coupling member and the decorative member protrude from the outer surface.

Disclosed is a phone case for diving comprising a housing including a rear housing rotatably connected to one side of front housing and sealingly connected to the other side, and a front housing. A surface of rear housing is connected with a photographing window on one side, and is further connected with an air suction assembly located on one side of photographing window and/or a light-filling assembly located on the other side of air suction assembly. The housing, connected with a function button, has a control module connected inside that is in signal connection with function button and light-filling assembly respectively and connected with phone by Bluetooth. Further disclosed is a method for implementing a phone case for diving, wherein air inside housing is extracted by air suction assembly, so that housing is vacuumed inside for good waterproof performance without steam appearing inside housing, making photographing effect better.

Systems and methods for operating a communication device. The methods comprise: monitoring, by the processor, states of snap-dome based switches of a keypad provided with the communication device; activating, by the processor, a first timer when the snap-dome based switches are simultaneously activated; detecting, by the processor, when maintenance of the communication device is needed based on a value of the first timer; and causing, by the processor, performance of communication device maintenance based on the detecting, for immersion time and immersion depth fatigue.

A mounting base (14) is fixed to an antenna (13) or an antenna bracket (15) for supporting the antenna (13). A baseband unit (11) and an RF unit (12) are fixed to the mounting base (14). The baseband unit (11) fixed to the mounting base (14) is disposed to face a back part (132) of the antenna (13) and to form a space between the back part (132) and the first enclosure (111). The RF unit (12) fixed to the mounting base (14) is disposed in the space formed between the back part (132) of the antenna (13) and the baseband unit (11) and is coupled to a waveguide flange (132) of the antenna (13). Thus, for example, in a configuration of a point-to-point wireless apparatus in which an RF unit and a baseband unit are separated, restrictions on installation space of the apparatus can be facilitated.

The invention provides a waterproof case suitable for a mobile electronic device, which comprises a controller for controlling the mobile electronic device, a connector connected with the mobile electronic device and capable of transmitting data with the controller, and an input device for a user to input a command to the controller to control the mobile electronic device, wherein the input device comprises an operating portion and a first light sensing assembly capable of controlling operations on a control screen by reading displacement of the operating portion. According to the invention, the connector can be directly plugged into an interface of the mobile electronic device and signals can be transmitted using an open standard code without downloading client software. The invention is universal for different types of mobile electronic devices.

A method for manufacturing a housing is described. The methods includes: providing a cover body defining a slot; filling a first material into the slot; and filling a second material into the slot to fill up the slot. A housing and a mobile terminal including the housing are further provided.
