    摘要: A method and system for battery pack cell state of charge balancing using a proportional-integral feedback control combined with a feedforward control. The proportional-integral feedback control acts on the difference between the average discharge for all cells over a previous driving cycle and the discharge of a specific cell over the previous driving cycle. Thus, the feedback term is based on whether an individual cell discharges more quickly or less quickly than the battery pack average during driving. A cell which discharges more quickly will receive decreased resistive discharge balancing. The feedforward control acts on the difference between an individual cell's state of charge and the battery pack average state of charge at the beginning of a current driving cycle. The overall control effort, which determines the resistive discharge balancing on-time duty cycle for each cell, is the sum of the feedback control signal and the feedforward control signal.

    摘要: This invention is a projector headlight that, while offering dual beam patterns, boasts a 100% utilization of the light emitted from a light source by one of the following methods: (1) employing a reflective cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern, (2) using reversible cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern with no moving part involved, (3) utilizing a selective light-filter cutoff means to selectively reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern without making use of any moving part, (4) using a low-beam light-emitting subassembly and a high-beam light-emitting subassembly that are separated by partition means to achieve dual beam patterns with no moving part, or (5) adopting a low-beam light-emitting subassembly in low-beam pattern and a high-beam light-emitting subassembly in high-beam pattern without any moving part.

    摘要: A system may create work units, each work unit including at least one of an input port or output port, each work unit configured to modify data that is received via the input port. In addition, the system may compose a workflow by connecting an output port of a first of the work units to an input port of a second of the work units, receive a work order, select the workflow in response to the work order, decompose the workflow into constituent work units, instantiate tasks that correspond to the constituent work units, and execute a work unit process for each of the tasks.
