An inductive charging method for vehicles includes a power sourcing (PS) device using a first frequency converter PS sub-module to detect a power receiving (PR) device. The PS microprocessor can compare ID codes of the PR device and check power receiving status data codes. When finding an incorrect power supply, the PS microprocessor will mark it and make other first frequency converter PS sub-modules to cut off power supply through the signal control circuit, and even adjust output power based on power status data codes from the PR device. As total voltage of the PR module is increased by series connection, it is not necessary to use components of high-voltage specifications and water cannot go into sockets, thus preventing electricity leakage. Besides, no wired connection is required and operations concerning identification, stored value or deductions can be carried out.

Methods for separation of oxygenates or other chemical components from fuels using chemical processes and separations including, but not limited to, onboard applications in vehicles. These separations may take place using a variety of materials and substances whereby a target material of interest is captured, held, and then released at a desired location and under desired conditions. In one set of experiments we demonstrated an enhancement in the separation of diaromatics by >38 times over gasoline and aromatics by >3.5 times over gasoline. This would give an advantage to reducing cold-start emissions, or emissions during transient conditions, in either gasoline or diesel.

The invention discloses an LED (Light Emitting Diode) surgery shadowless lamp with multiple lens light source arrays and a method for revising the shadowless rate, relates to the technical field of a lighting lamp, in particular to the structure improvement aspect of the surgery shadowless lamp which is used in the surgery course. In order to solve the technical problems that the traditional surgery shadowless lamp has single control mode and unsatisfactory shadowless rate processing effect and influences the normal surgery operation, LED lamps on a central lamp source plate and a side lamp source plate are controlled by regions; and shielded ineffective LED lamps are turned off by a control circuit according to different shielding conditions, thereby prompting the brightness of other effective LED lamps to repair the shadow. By presetting various lighting modes which are suitable for different shielding conditions, the shadow problem is effectively solved; according to different shielding conditions, the system turns off the shielded ineffective LED light sources and selectively improves the brightness of other effective LED light sources to repair the shadow, thereby improving the shadowless lighting effect and enhancing the shadowless rate to 98%.
