The disclosure generally relates to power over fiber technology configured to provide electrical power and communications via fiber to one or more sensors of one or more varieties. More particularly, the disclosure relates to a sensor system comprising a laser data module operatively connected to a powered sensor module, wherein the powered sensor module receives a light, converts the light to electrical power, and powers a sensor with the electrical power, and wherein the powered sensor module transmits signals from the sensor to a laser data module.

Power over fiber enabled sensor system

Provided is a photovoltaic power converter receiver, including a photovoltaic cell, a waveguide coupled to the photovoltaic cell, and an optical transmission device of which an end is coupled to the waveguide for transmitting an optical wave to the photovoltaic cell through the waveguide, wherein the end of the optical transmission device is offset from a longitudinal central axis of the waveguide by a distance D.

Plumbing supply boxes may be made of a thermoset plastic material that will not melt or permit the boxes to collapse inside a wall if subjected to flames or high temperatures resulting from a fire. If the thermoset plastic boxes have a drain opening, a thermoplastic tubular drain adaptor may be connected thereto that can be solvent welded. Relatively small intumescent pads may be installed in close proximity to the drain opening which, if subjected to flames or high temperature caused by a fire, will expand and form an insulating char that seals off the drain opening. The boxes may be slidable in opposite directions along adjustable support brackets to permit the boxes to be mounted in any desired position in stud bays having different spacings between the stud walls for ease of alignment of one or more openings in the box with in-wall plumbing.

Extremely fast dynamic control is allowed for hybrid PV/T (photovoltaic/thermal) distributed power production using concentrated solar power by manipulating the transmissive or reflective state of a capture element or mirror or lens that can pass highly concentrated solar light from one energy conversion device to another, such as a thermal collector and a photovoltaic receiver, such as a vertical multijunction cell array. This allows superior quality electrical backfeed into an electric utility, enhanced plant electrical production revenue, and responsiveness to a multitude of conditions to meet new stringent engineering requirements for distributed power plants. The mirror or lens can be physically articulated using fast changing of a spatial variable, or can be a fixed smart material that changes state. A mechanical jitter or variable state jitter can be applied to the capture element, including at utility electric grid line frequency.

Utility-friendly hybrid energy conversion system for apportioning concentrated solar radiation in real time upon selective demand between a plurality of solar energy conversion devices, including a photovoltaic receiver

Provided is a solar collector assembly that can be manufactured, assembled, and maintained efficiently. A number of arrays that include one or more reflective material formed in a parabolic shape can be attached to a backbone. The backbone is attached to a polar support that is positioned at or near the center of gravity for the solar collector assembly. The polar support at or near the center of gravity allows the entire assembly to be tilted, rotated and/or lowered for various purposes (e.g., service, maintenance, safety). The solar collector assembly can be transported as modular units and/or in a partially assembled state.

Mass producible solar collector

System(s) and method(s) are provided for assembling and utilizing parabolic reflectors in a solar concentrator. Parabolic reflectors assembly starts with a low-cost, flat reflective material that is bent into a parabolic or trough shape via a set of support ribs that are affixed in a support beam. The parabolic reflectors are mounted on a support frame in various panels or arrays to form a parabolic solar concentrator. Each parabolic reflector focuses light in a line segment pattern. Light beam pattern focused onto a receiver via the parabolic solar concentrator can be optimized. The receiver is attached to the support frame, opposite the parabolic reflector arrays, and includes a photovoltaic (PV) module and a heat harvesting element that enable dual-mode energy conversion operation. To increase performance of the parabolic solar concentrator, the PV module can be configured to advantageously exploit a light beam pattern optimization regardless irregularities in the pattern.

Light beam pattern and photovoltaic elements layout

A solar collector can be rotated and tilted about a polar mount. The solar collector can be designed such that the center of gravity of the collector is aligned with the axis of the polar mount facilitating the use of smaller positioning devices. The collector can be placed in a position to prevent damage by inclement weather and allow easy access for maintenance and installation.
