  • Patent number: 7701361
    Abstract: A parking information sensing device is disclosed. Each parking space in a parking lot is disposed with a parking information sensing device, detecting whether a car on the parking space. By means of a driving control circuit, the sensing device drives a light emitting unit to emit a light and a reflecting element of the parking space is on a pathway of the light. Light is reflected by the reflecting element and then passes light sensing unit that detects the reflected light and generates a first sensing signal sent to the driving control circuit. Thus the driving control circuit judges if there is no vehicle on the parking space. On the other hand, it judges if there is a car on the parking space according to another sensing signal. The sensing device further includes a first transmitting/receiving unit that forms a wireless mesh network among parking information sensing devices.

  • Publication number: 20080109136
    Abstract: The present invention relates to an adjustable crash trigger apparatus and a method thereof. The adjustable crash trigger apparatus according to the present invention includes a power supply module, an electronic accelerometer module, and a microcontroller module, which includes at least a real-time processing unit and a beacon-activated command unit. The apparatus and the method thereof are used to judge if a vehicle satisfies is about to collide. When it is judged true, an emergency transmitting device is activated, and the vehicle is located. In addition, the apparatus according to the present invention is electronic type and can judge three axes. The threshold acceleration value is adjusted depending on the type of the vehicle. Thereby, high sensitivity, low false alarm rate, and low failure rate can be achieved.
