Abstract: A safe driving system includes an acquisition module, a determination module, a control module, and an alarm module. The acquisition module acquires data indicating a driving state of a vehicle and a physical state of a driver of the vehicle. The determination module compares the data obtained by the acquisition module with a plurality of preset values and a plurality of preset time ranges, and thereby determines that the vehicle is in a dangerous driving state and determine associated with the dangerous driving state, and upon such determination, send a signal to a control module. The control module is configured to activate the alarm module to issue an alarm to prompt the driver to calmly drive the vehicle upon receipt of the signal from the determination module.

Abstract: An automatic locking mechanism is configured to lock a housing with a latching groove. The automatic locking mechanism includes a bracket and a magnet. An inclined surface is defined on an edge of the magnet. The bracket defines a groove. A restriction member is positioned in the groove configured to restrict the magnet. The housing is locked to the bracket when the magnet is simultaneously received in both the groove and the latching groove via the attraction of the magnet to the housing. The housing is released when the housing is continuously resisted against the inclined surface of the magnet until the magnet is completely received in the groove. In addition, an electronic device with the automatic locking mechanism is disclosed.

Abstract: A warning system applied to a vehicle includes a control module, a detecting module, a warning module, and a pressure sensor module. The pressure sensor module is assembled to a seat, and configured to measure a pressure value of the seat and transmit the pressure value to the control module. The detecting module is configured to obtain information of the environment around the vehicle and transmit the information to the control module. The control module is configured to determine whether there is at least one person sitting on the seat based on the pressure value on the seat, and to determine whether there is a passing vehicle based on the information of the environment surrounding the vehicle, and warn the passing vehicle when there is someone sitting on the seat and there is a passing vehicle.

Abstract: An electronic device comprises a housing defining an inserting slit configured to receive a memory card, a printed circuit board configured to be installed within the housing, a card reader installed in the housing and electrically coupled to the printed circuit board, and an elastic cover coupled to the housing and configured to cover the inserting slit. The card reader is configured to be substantially adjacent to the inserting slit. The elastic cover defines a slot for guiding the memory card to a receiving portion of the card reader. The elastic cover is configured to deform and expose the memory card upon depression, so that the memory card is ejected out of the housing via the slot.

Abstract: A driving safety system for a vehicle includes a housing, a camera positioned on the housing, and a controller positioned on the housing and electrically coupled to the camera. The controller includes a plurality of modules whereby the camera captures images of the scene in front of the vehicle and an image identification module identifies a traffic light state and a value of a countdown timer in real time from the captured images and sends a corresponding signal to the micro control unit, then the micro control unit will warn the driver as to the states of the traffic lights and countdown timer. A vehicle using the driving safety system is also disclosed.

Abstract: An electronic device includes a housing, a card reader, and a cover. The housing includes a slot and two protrusions defined on the inner wall of the housing. The cover includes a body and two connection ends. The body is for covering the slot. The connection ends extend from the body. Each of the two connection ends includes a sliding slot which receives one of the two protrusions respectively to guide the two connection ends to slide. When the cover covers the card which contains a memory card therein, the cover is operable to be pressed to eject the memory card. When the memory card is ejected, it push the body of the cover to cause the two connection ends to slide along the two protrusions to make the body of the cover uncover the slot and rotate to expose the memory card.

Abstract: A speaker with acoustic chamber is provided. The speaker includes a main body and an acoustic chamber fixed to the main body. The acoustic chamber can be converted between a collapsed state and an expanded state. The acoustic chamber is drawn to the expanded state to increase the volume of the acoustic chamber and is collapsed to the collapsed state to decrease the volume of the acoustic chamber. When the acoustic chamber is drawn to the expanded state, the quality of the sound output by the speaker is improved.

Abstract: The electronic device includes a body and an adjustable strap. The adjustable strap includes a first strap, a second strap, a first slider, and a second slider. Each of the first and second sliders defines a rail in the middle thereof and two through holes of each slider are formed via the rail. One end of the first strap is connected to one end of the body, and the other end passes through one through hole of the first slider and one through hole of the second slider. Then it is connected to the second slider; one end of the second strap is connected to the other end of the body, and the other end passes through the other through hole of the second slider and the other through hole of the first slider, and then is connected to the first slider.

Abstract: An indication device includes a substrate, a printed image, and a backlight source. The substrate is transparent or semi-transparent. The printed image is printed on a surface of the substrate and includes a first sub-image with a first color and a second sub-image with a second color. The backlight source setting on an opposite second surface of the substrate and capable of emit different color light.

Abstract: A device includes a housing, an interface port protection cover, at least one slots, and at least one connecting members which includes a connecting portion and a sliding portion. Each connecting member defines a guide slot along a longitudinal direction of the sliding portion. The connecting portion is connected to the cover, and the sliding portion extends through the corresponding slot. The housing defines one guide protrusion and one limiting protrusion protruding from a bottom thereof corresponding to each slot. The guide protrusion and the limiting protrusion are slidably received in the guide slot, and one end of the guide slot resists against the limiting protrusion. When a user mistakenly attempts to rotate the cover by moving a first end of the cover which is adjacent to the sliding portion, the end of the guide slot resists against the limiting protrusion and the protection cover cannot move.
