  • 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.

  • Patent number: 7586405
    Abstract: A motorcycle awareness system for use when a motorcycle is in operation in conjunction with vehicular traffic is disclosed. The motorcycle awareness system includes an infrared light emitter that is located on the front of a motorcycle, with the infrared light emitter having an internal oscillating motor that is attached to an emitter. The emitter continually emits infrared light in a forward manner once it is turned on and emits this light in a sweeping manner. Vehicles would be equipped with an infrared light receiver, which, when infrared light is received, would activate a number of lights that are attached to the receiver. The lights are preferably either yellow or blue to distinguish these lights from other vehicular lights. When activated, the lights signify the presence of a motorcycle in close proximity to the vehicle, thereby notifying the driver to pay extra attention while driving so as to not endanger the motorcyclist.

  • Patent number: 7386237
    Abstract: A battery powered transmitter circuit has a LED of a continuously cycling microcomputer transmit a beam of a predetermined number of infrared pulses at predetermined time periods to a sensor of a battery powered receiver circuit. Only a clock circuit of each circuit of the same frequency is continuously powered. The two clock circuits are synchronized each time that the sensor senses the predetermined number of infrared pulses. When an object breaks the beam, the sensor causes a count of the object by a microcomputer of the receiver circuit. The receiver microcomputer is inactivated when the sensor does not sense the predetermined number of infrared pulses during one or more cycles of operation of the receiver microcomputer. There is only one count incremented on a count display after the beam is interrupted until the sensor again senses the predetermined number of infrared pulses.
