    摘要： A foldable portable electronic device, a system and a method for protecting a built-in hard disk thereof are disclosed. The foldable portable electronic device includes a display and a main body. The system includes a trigger, a lid switch, and a logic judgment module. When the foldable portable electronic device is away form a flat surface, the trigger generates a first signal; when the display is folded onto the main body, the lid switch generates a second signal. The logic judgment module determines the method to control and protect the hard disk in accordance with the first signal and the second signal.

    摘要： A toy phonograph comprises means for pressing a pickup arm into engagement with a phonograph record for reproducing recorded sound from the phonograph record playing surface during rotation thereof. The sound is picked up from a sound reproducing groove in the playing surface by direct resilient contact of a speaker cone assembly with the pickup arm. The speaker cone assembly includes a lift bar containing an aperture adjacent the end of the recording with a protrusion on the pickup arm being received in the aperture as the pickup arm reaches the end of the recording. The drive means for the turntable has an associated electrical contact located between the phonograph record playing surface and the lift bar. When the protrusion is received in the lift bar aperture, the lift bar drops a sufficient amount to engage a leaf spring contact which is normally biased to a closed circuit condition to open the circuit and thus shut off the drive means. Two records may be provided on opposite sides of a common turntable with two separate identical means connected in parallel so that the common turntable may be driven if either of the respective pickup arm protrusions is not received in its respective lift bar aperture. The device may function as a talking toy bank responsive to insertion of a coin.

    摘要： A railway crossing programmable device includes a communication module in signal communication with a central server for authentication of a user to use the programmable device to modify the railway system circuit. The programmable device further includes a circuit modification module configured for electrical coupling to a railway system circuit for modifying an electrical connection of the railway system circuit in a programmed manner. The programmable device further includes a user interface configured to receive user data and display output information related to at least one of a user, a device, and a circuit modification.
