Abstract: Systems for circumferentially microtoming a pipe having a longitudinal axis. The systems include a frame, a lathe, a carriage, a cutting tool, and an actuator. The lathe is mounted to the frame and configured to support and rotate the pipe about the longitudinal axis of the pipe. The carriage is operatively supported on the frame proximate the pipe. The cutting tool selectively engages the pipe. The actuator is operatively supported on the frame and configured to move the carriage to different radial positions perpendicular to the longitudinal axis of the pipe. In some examples, the system includes a position sensor, a computer display, and/or a controller.

Abstract: The present disclosure is directed to solar module covers. A device may include a first surface and a second, opposite surface configured to be positioned proximate at least one solar module and contact at least one of a frame of the at least one solar module and a roof. The device may be sufficiently rigid to distribute at least some of an external force applied to the first surface away from a laminate of the at least one solar module.

Abstract: The present disclosure is directed to a methods, devices, and systems communicatively coupling a solar system to a network. A system may include a local router and a solar gateway. The solar gateway may include an interface for coupling to a network via the local router and a long-range module for coupling to the network via at least one other solar gateway.

Abstract: The present disclosure is related to community virtual net metering of photovoltaic systems. A method may include identifying at least two photovoltaic (PV) system customers in a single geographical area. The method may also include crediting power overproduction of a first PV system customer of the at least two PV system customers to a second, different PV system customer of the at least two PV system customers.

Abstract: An application integration driver infrastructure for facilitating the use of a distributed directory running in a computer network is provided. The infrastructure can transform specific directory events into a vendor-neutral data identification system and then use vendor-neutral transformation technologies to transform the neutral data identification into a specific application's data format, and vice-versa. The infrastructure receives an event from the distributed directory into a markup language generation system, such as an extensible markup language (“XML”) generator. The XML generator converts the event into XML data and provides the XML data to a transformation processing system, such as an extensible transformation language (“XSLT”) processor. The XSLT processor transforms the XML data to a predetermined format. The format can be dictated by a stylesheet provided to the XSLT processor, the stylesheet being responsive to requirements of a computer application.
