Abstract: The invention discloses a multifunctional bed, a multi-drive switch protection circuit and its control device, wherein in the multifunctional bed, when a switch group is not triggered to start by a user, all electric signal transmission paths are in a disconnected state, and after the switch group is operated to start by the user, an MOSFET unit is controlled to be conducted after delaying an arc extinguishing time period according to the arc extinguishing time preset by a micro control unit, so that the corresponding electric signal transmission paths are conducted, and a load driving device connected with the switch group runs after the switch group is triggered to start and the arc extinguishing time period is separated, so that a bed component of a bed main body is driven to adjust the corresponding posture.

Abstract: A solar-powered hybrid vehicle disclosed in the present invention comprises a vehicle body, a vehicle energy configuration system, and a brake energy recovery system. The vehicle body collects solar energy through a collection system of solar energy. The solar energy collected is stored in the vehicle energy configuration system of the vehicle. The brake energy recovery device is connected with a battery through a solar charging circuit. A sensor is provided between the vehicle energy configuration system and the battery. The body energy configure system is connected with an automatic control system, an external charging interface and an electric motor. Through the integration of a number of technical solutions, the present invention reduces energy consumption, improves the level of utilization of solar energy, and is more fashionable and fit for human use.

Abstract: A system and method for reducing the distance of the understanding and expectation between a buyer and seller for a price of a particular product that is offered for sale. The system and method permit buyer to use their volume purchase power to lower the price of demanded product, and pay only the fair market value of the product in that the price is much lower than the price expectation or requirement of the buyer. Conversely, the system and method permit sellers to reach a targeted market in which a group of buyers are available for desired product. The seller is provided with the benefits associated with low cost competition by reducing the distribution cost and increasing the operation efficiency, such as increased inventory turnover rate, based on the advantages associated with volume sales.
