摘要:
A battery monitoring system comprises a battery control unit (BCU) and a plurality of module control units (MCUs) connectable to battery modules. The BCU comprises a low voltage power supply, a BCU controller, and a reference address signal source connected to an address signaling path. The MCUs receive low voltage power from the BCU. Each MCU comprises an address signal input and output with a signal coupler therebetween for connecting the module control unit along the address signaling path, and an MCU controller. The BCU controller determines a number of MCUs on the address signaling path, and each MCU controller determines the associated MCU's position along the address signaling path, based at least in part on a detected signal on the address signaling path and predetermined properties of the reference address signal and address signal coupler. A ground fault detection unit may provide a fault signal to the BCU controller.

In a method of producing fibers having property enhancing inclusions, a molten material is supplied to a fiber forming apparatus. A controlled amount of particulate is added to the molten material. The molten material with the added particulate is formed into fibers. An undissolved portion of the added particulate forms inclusions in the fibers, the inclusions having an absorption index in a 2-7 μm wavelength region that is greater than a corresponding absorption index of the material.

The present invention relates to fiberglass loose-fill insulation that is insensitive to the content of boron in the composition of the glass. It has been discovered that the level of boron in the glass used for the manufacture of loose-fill glass wool can be substantially reduced without degrading thermal performance. The lowered amount of boron provides for a lower cost batch composition and increased furnace life. The glass composition of the present invention includes a substantially reduced content of boron and preferably an increased amount of sodium dioxide. The primary phase of these glass compositions is typically devitrite (Na2Ca3Si6O16). The glass of the present invention provides a glass fiber blowing wool that does not require an increase in pack density to compensate for the reduced boron content while achieving the similar thermal conductivity. The glass of the present invention is also suitable for use in acoustic insulation.

摘要:
A method of manufacturing a roofing shingle includes coating a continuously supplied shingle mat with roofing asphalt to make an asphalt coated sheet. A first portion of granules is applied onto the asphalt coated sheet, wherein the first portion contains substantially no anti-microorganism granules. A second portion of granules is applied over the first portion of granules, wherein the second portion of granules comprises granules and anti-microorganism granules. The granules and anti-microorganism granules which are not adhered to the asphalt coated sheet are the removed.
