Abstract: Dynamic allocation of power modules for charging electric vehicles is described herein. The charging system includes multiple dispensers that each include one or more power modules that can supply power to any one of the dispensers at a time. A dispenser includes a first power bus that is switchably connected to one or more local power modules and switchably connected to one or more power modules located remotely in another dispenser. The one or more local power modules are switchably connected to a second power bus in the other dispenser. The dispenser includes a control unit that is to cause the local power modules and the remote power modules to switchably connect and disconnect from the first power bus to dynamically allocate the power modules between the dispenser and the other dispenser.

Abstract: A brush holder includes a generally cylindrical container with an inner annular flange close to its open end and a raised brush support which defines a lower liquid reservoir. The annular flange is preferably inclined toward the bottom of the container or, alternatively, is perforated. The dimensions of the annular flange are chosen such that when a brush is inserted into the container and removed from the container, the flange squeezes the brush. As the brush is squeezed, liquid is removed from the brush and drips into the liquid reservoir. The brush support is preferably a raised central portion of the container floor which defines an annular reservoir or, alternatively, the brush support may be formed as a perforated disk which is spaced above the floor of the container. The brush support keeps the brush out of the reservoir so that the brush will remain dry.

Abstract: A coated abrasive having improved properties of grinding performance and brittleness, said abrasive comprising a backing and an abrasive coating adhered thereon wherein the abrasive coating comprises a suspension containing lapping size abrasive grains and a binder, said binder containing a diacrylated monomer and a triacrylated or higher acrylated monomer.

Abstract: The present invention is a device for generating a plurality of colors of light from a light source. The device includes a plurality of filters to separate the light at predetermined wavelengths and to recombine them at different amplitudes to generate a predetermined color hue in the visible spectrum of light.
