摘要:
This invention is an intruder detection system which integrates wireless sensor network and security robots. Multiple ZigBee wireless sensor modules installed in the environment can detect intruders and abnormal conditions with various sensors, and transmit alert to the monitoring center and security robot via the wireless mesh network. The robot can navigate in the environment autonomously and approach to a target place using its localization system. If any possible intruder is detected, the robot can approach to that location, and transmit images to the mobile devices of the securities and users, in order to determine the exact situation in real time.

A simplified universal remote control includes a remote control body, a set-top box playing/pause button, a mute mode button, volume adjustment buttons, channel switching buttons, a control module, and a wireless transmission module. The remote control body includes a holding piece extended in a left-lower direction and a holding piece extended in a right-lower direction. The control module receives an operation signal from the operation interface and transmits a control signal. The wireless transmission module transmits the control signal to drive switching of playing and pause of a set-top box, switching of a mute mode, adjusting volume, or switching channels, so that a simplified, concise, and reasonable arrangement of buttons is provided to help greatly reduce the risk of erroneous button touch or push so as to realize the most optimum and most intuitive experience of use.

A protective case for a portable electronic device includes a bottom plate, a frame, and a glass substrate. The bottom plate has at least one hole and a flange around a periphery thereof. The frame is connected to the bottom plate. The frame has at least one through hole. An inner peripheral edge of the frame is provided with an engaging groove. The flange is engaged in the engaging groove. The frame cooperates with the bottom plate to form an accommodation space for accommodating a portable electronic device. A side of the bottom plate, opposite to the accommodation space, cooperates with the frame to form an accommodation trough. The glass substrate corresponds in shape to the accommodation trough. An adhesive layer is provided between the bottom plate and the glass substrate. The glass substrate is adhesively disposed in the accommodation trough.

A cell phone protection cover structure includes a battery cover, a support plate, a leather cover, and a protection plate. The battery cover is mounted to the back of the cell phone. The battery cover has a thick portion and a thin portion. The thick portion is directly adhered to the leather cover. The support plate corresponds to the thin portion of the battery cover and is adhered to the leather cover. The leather cover has a connecting section to connect with the protection plate. The support plate can be coupled to the thin portion of the battery cover to form the same plane with the thick portion. The support plate can be opened at an angle, so that the battery cover, the support plate and the protection plate form a triangle support for the cell phone to be placed obliquely.

An airflow guiding and heat dissipating assembly is mounted in an electronic device and has a base and at least one baffle being mounted on the base. Multiple electronic components are mounted on the base and are arranged in a line. Airflow flows along one electronic component upstream, past the baffle and then over the other electronic component downstream to take away heat from the electronic component. The baffle prevents the airflow from becoming turbulent and, therefore, temperatures of the electronic component are lowered efficiently.

A liquid cooled heat sink has a thermal conduction plate and a liquid cooling module. The liquid cooling module is attached securely to the thermal conduction plate and has a distribution tank, a collection tank and a pipe assembly. The pipe assembly has multiple pipes of at least two different gauges and each pipe has a pipe inlet and a pipe outlet respectively secured to the distribution tank and the collection tank. Since a sum of the gauges is increased and each pipe need not to be coiled, an extra strong pumping system is not needed and design complexity is reduced.

A mobile phone screen protector device includes a positioning seat, a positioning frame, an auxiliary adhesive sheet, a screen protector, and a scraper. The positioning seat has a first raised portion, a second raised portion, and a positioning space between the first and second raised portions for accommodating a mobile phone with a screen facing upward. The first raised portion is higher than the second raised portion. The auxiliary adhesive sheet is adhered to an underside of the positioning frame. The screen protector is adhered to an underside of the auxiliary adhesive sheet. The positioning frame and the auxiliary adhesive sheet are confined to the tops of the first and second raised portions, and the screen protector is inclined at an angle relative to the screen. The scraper is pressed to scrape against the auxiliary adhesive sheet for the screen protector to be adhered to the screen.
