  • Patent number: 10140865
    Abstract: A system may include a storage device that stores a set of instructions and a processor in communication with the storage device. When executing the set of instructions, the processor may be configured to cause the system to obtain, from a user terminal, a first geographical location via a network and obtain a second geographical location associated with a virtual parking region. The first geographical location may be determined by the user terminal according a GPS signal. The virtual parking region may include parking space for vehicles. The processor may also be configured to cause the system to determine whether a distance between the first geographical location and the second geographical location is less than a threshold and obtain information associated with the virtual parking region in response to the determination that the distance is less than the threshold.

  • Patent number: 8342892
    Abstract: The high conductivity energy-saving clamping device comprises a clamp and a cable fixed upon the clamp. Inside the cable, the conductive material protrudes and is set on the juncture of the clamp and the external conductor. When the clamp is connected to the external conductor, the conductive material and the external conductor contact and meet. This invention possesses the following advantages: it simplifies the production technology, lessens raw materials needed for production and hence saves resources and cost by the direct contact of the conductive material and the external conductor; moreover, due to the increase of conductive contact area, it enhances the electrical conductivity by 10% to 15% compared to those common clamps which use tooth-like conductive parts to connect the external conductor. Meanwhile, the invention greatly decreases environmental pollution by omitting the plating process of tooth-like conductive parts.
