Abstract:
An electronic wallet for accessing a credit card account information includes a card reader, a processor, a touch screen, a radio frequency (RF) module, and an antenna. The card reader, the touch screen, and the RF module are electrically connected to processor. The card reader is adapted to read card number and correlation information of the credit card. The processor receives the card number and correlation information from the card reader to identify the credit card issuer, and sends a control signal to the touch screen to display a login interface of the identified credit card issuer. The touch screen allows users to input the card number and password on the login interface. The processor encrypts the card number and the password. The RF module converts an encrypted signal received from the processor to RF signals, and sends the RF signals to networks through the antenna.
Abstract:
A system and method for vehicle rental management generates and displays a park identification (ID) number configurable to change periodically. The method further receives a first message containing a vehicle ID number of a vehicle from a mobile phone, sends a unlock code for unlocking the vehicle to the mobile phone. The method receives a second message containing the vehicle ID number and a park ID number from the mobile phone, and sends a lock signal to the second communication module to lock the vehicle. The method receives a feedback signal for confirming that the vehicle is locked, and times between the send the unlock code step and the receive the feedback signal step.
Abstract:
A portable electronic device includes a main body, at least one first rotary arm rotatably connected to the main body, and at least one second rotary arm rotatably connected to the main body. At least one connection port is located on at least one of the first rotary arm and the second rotary arm. When the at least one first rotary arm and the at least one second rotary arm are flush with the main body, the at least one connection port is hidden. By rotating the at least one first rotary arm or the at least one second rotary arm until the at least one first rotary arm or the at least one second rotary arm is not flush with the main body, the at least one connection port is exposed.
Abstract:
A mouse includes a housing, a circuit board received in the housing, and a battery chamber received in the housing and configured for receiving a battery therein. The circuit board includes a USB mouse operating circuit, a charging circuit and a USB connector. The USB mouse operating circuit and the charging circuit are both connected to the USB connector. The battery chamber includes at least one charging connector connected to the charging circuit. The charging connector connects the charging circuit with the battery received in the battery chamber.
Abstract:
A charging device comprises a rotating unit, an axle unit assembled to the rotating unit and engaging the rotating unit, and two charging units assembled to the axle unit. Each charging unit includes a magnet retainer assembled to the axle unit and engaging the axle unit, a plurality of magnets received in the magnet retainer, and a case rotatably assembled to the axle unit and including a plurality of windings. Rotation of the rotating unit drives the axle unit and the magnet retainers to rotate, the rotating magnet retainers and magnets further rotate relative to the cases due to the inertia of the cases, and the magnets move relative to the windings and generate induction currents in the windings, for charging a battery.
Abstract:
An earphone jack includes a main body, a number of guiding plates, at least one positioning plate, a number of blades, and a frame. The main body defines a hole. The guiding plates surround the hole, and the positioning plate is formed on the guiding plates. The blades rotatably engage with the guiding plates. The frame is mounted with the blades. When the frame is rotated, the blades moves along the guiding plates to allow the blades to provide different latching spaces for receiving different sizes earphone plugs.
