This invention discloses improved residential roofing products with durable active protection against algae discoloration. Versatile organometallic salts and chelates for this purpose are incorporated in manufacture of composite concrete tile and asphalt shingle products via integrated process modifications. These chemically stable non-volatile microbiocides, with exceptional effectiveness against both green and blue green algae, are tailored for specific matrix compatibility. By virtue of their composition and surface activity they serve a dual function in process improvement and product performance. The control of microbiocide activity, long term, significantly advances the state-of-the-art protection against algae and the service life of these products.

A switch encapsulates incoming information using a header, and removes the header upon egress. The header is used by both distributed ingress nodes and within a distributed core to facilitate switching. The ingress and egress elements preferably support Ethernet or other protocol providing connectionless media with a stateful connection. Preferred switches include management protocols for discovering which elements are connected, for constructing appropriate connection tables, for designating a master element, and for resolving failures and off-line conditions among the switches. Secure data protocol (SDP), port to port (PTP) protocol, and active/active protection service (AAPS) are all preferably implemented. Systems and methods contemplated herein can advantageously use Strict Ring Topology (SRT), and conf configure the topology automatically. Components of a distributed switching fabric can be geographically separated by at least one kilometer, and in some cases by over 150 kilometers.

The invention provides an electric vehicle inverter protective device. A gate control signal is output to the gate of an IGBT through a driving circuit and a buffer circuit. An auxiliary power supply converts the power of an inverter controller into voltage controlling the on-off state of the IGBT and supplying power to the driving circuit. A bus voltage detection circuit determines whether bus voltage is higher than a bus high-voltage threshold value and outputs a voltage comparison signal to the inverter controller. An emergency circuit is powered by the bus voltage and outputs a gate signal to control the conduction of IGBTs at a three-phase lower half-bridge in order that the inverter is in an active short-circuit mode. Further, the inverter controller may output a reset signal to reset the driving circuit. The invention further provides an electric vehicle inverter protective method. The electric vehicle inverter protective device provides an active safe mode for the trailed condition of an electric vehicle, may detect the operating parameter of the inverter in real time, may isolate the high-voltage power from the low-voltage power of the inverter, and performs active protection on an electric vehicle inverter.
