Abstract: A data center rack door having a curved permeable member is disposed vertically along a front-face of a data center rack. The curved permeable member provides an increase in surface area that provides for additional openings, increasing airflow through the data center rack. The curved permeable member also provides an increase in volume of space in the data center rack.

Abstract: A telecommunication energy management system comprising a server configured to receive circuit current values identified with a respective piece of telecommunication equipment from a plurality of central boards located at respective telecommunication sites. The server integrates the received circuit current values and provides a graphical user interface (GUI) to allow a user to audit energy usage of each piece of telecommunication equipment of each telecommunication site.

Abstract: A telecommunication wireless site control system comprising a central control board configured to receive control signals disposed at a wireless site. The central control board may be communicatively coupled with current monitor and control boards, extension boards, and a local switch to control telecommunication equipment, power devices, and controllers.

Abstract: A blood analyte measurement system is configured to receive a test strip. An LED proximate to the test strip is used to illuminate the test strip and, in conjunction with a photodiode, to determine its type. A compensation circuit of the measurement system insures that ambient light does not cause interference with the LED illumination to prevent saturation of the photodiode.

Abstract: A thermochromic indicator is vertically disposed on a rack. Such that the thermochromic indicator is visible from a distance. In some examples, the thermochromic indicator indicates a bulk air temperature and a gradient air temperature. The thermochromic indicator provides a real-time visual of air temperatures of computing equipment and devices housed within a computing facility. The thermochromic indicator may be vertically disposed on a front-face and/or a back-face or a rack. A plurality of thermochromic indicators may be disposed on a plurality of front-faces and/or back-faces of racks of an array of racks.

Abstract: A telecommunications infrastructure includes first and second trough members for routing signal-carrying fibers. Coupling members may be used to adjustably couple a first trough member arranged alongside a second trough member together. Coupling members may also be used to adjustably couple a first trough member together with a second trough member terminating at the first trough member.

Abstract: A trunnion seal assembly for joining a stationary inlet/outlet box of a ball tube mill to a rotational interior of the ball tube mill includes an outer ring component configured to be mounted to an outer wall of the stationary inlet/outlet box. An inner ring component is joined to the outer ring component substantially concentrically with the outer ring component. A flexible pad seal is configured to be joined to the outer wall of the stationary inlet/outlet box proximate outer ring component. The pad seal includes a first annular sealing surface. A mill head extension ring configured to be joined to a rotational mill head is located proximate to and substantially concentric with the inner ring component. The mill head extension includes a second annular sealing surface sealingly engaged with the first annular sealing surface of the flexible pad seal.

Abstract: A downhole plug for plugging and method of controlling fluids within a borehole in an oil and/or gas well. The downhole plug has a body having a throughbore for the passage of fluids. The plug also has a mechanical anchoring device that can radially expand an anchoring member on an outer surface of the body to lock the body in a fixed axial position within the borehole and an annular sealing device that can radially expand a sealing member on the outer surface of the body to seal an annulus formed between the outer surface of the body and an inner surface of the borehole. The plug also has a throughbore plugging device that can change configuration between a first open configuration in which the throughbore of the body permits the passage of fluid, and a second closed configuration in which the throughbore resists the passage of fluid.

Abstract: A low-resistance telecommunications power distribution panel provides a lower electrical resistance than traditional telecommunications power distribution panels, where the lower electrical resistance provides a reduced amount of waste heat. The low-resistance telecommunications power distribution panel may comprise a single unitary metal busbar configured to directly interconnect a power input cable to a plurality of fuse holders. A plurality of single unitary metal strips may directly connect to each fuse holder, each single unitary metal strip configured to directly connect to a power output lead. A single unitary metal return busbar may directly connect a return input to a plurality of return outputs.
