Abstract: A data center inside a shipping container having a lower plenum and an upper plenum in its interior. Heated air in the upper plenum exits therefrom into a plurality of heat exchangers adjacent thereto. Air cooled by the heat exchangers travels toward and enters the lower plenum. The data center includes a plurality of carriages each having an equipment receiving portion located between an open bottom portion in open communication with the lower plenum, and an open top portion in open communication with the upper plenum. Fans inside each of the carriages draw cooled air up from the lower plenum into the open bottom portion of the carriage, blow the cooled air up through the equipment receiving portion thereby cooling any computing equipment received therein, and vent the cooled air through the open top portion into the upper plenum.

Abstract: A thermal dispersion flow meter with chronometric monitor for fluid leak detection includes an ambient temperature RTD sensor and a flow rate RTD sensor which are configured to sense the temperature of a fluid in a conduit, and then monitor the flow of that fluid through the conduit. The fluid flow RTD sensor is incorporated into a Wheatstone bridge circuit which is used to provide increased sensitivity to the outputs of the RTD sensors. Based upon the ambient temperature sensor readings, the flow rate RTD sensor may be adjusted to optimize the operation of the system to detect leaks, and on certain conditions, a controller may close a supply line valve to avoid flooding of a structure.

Abstract: Optically controlled micro-electromechanical systems (MEMS) is disclosed. In one embodiment, a MEMS device may include a rotatable mirror having an optical sensor that is in electrical communication with the rotatable mirror via an associated electrode. Electrical potential may be supplied to an appropriately configured optical sensor so that a variable range of voltages may be supplied to the rotatable mirror. In operation, an optical control beam may be directed onto the optical sensor where it may be sampled to determine its optical characteristics (e.g., optical wavelength, light intensity, position, polarization, duty cycle, etc.) The optical sensor may then supply voltage to the rotatable mirror based on the determined optical characteristics of the optical control beam, causing the rotatable mirror to rotate about one or more axes.

Abstract: A conveyor belt cleaning apparatus includes a debris-removal stage, a washing stage, a rinsing stage, and a water removal stage all positioned in a multi-chambered drawer with each of the four stages is provided with an isolated bin within that drawer. The various stages within the conveyor belt cleaning apparatus provide for the continuous or on-demand cleaning of a conveyor belt in order to remove any debris and fluids from the belt thereby providing a clean belt surface for use by the grocery store customer. The device may be installed as a new element in a check stand, or it may be retrofitted to an existing check stand.

Abstract: A folding portable table includes an upper table surface, a number of folding table legs, and a lower table surface held between the legs by pins protruding from the perimeter of the lower table surface and slidably retained in grooves in the legs. The pins slide up and down in the grooves, allowing the lower table surface to be raised up to, or lowered down from, the upper table surface. When the lower table surface is raised up adjacent to the upper table surface, the legs can be folded under the upper table surface for transport and storage of the table. The table can be deployed by unfolding the legs and lowering the lower table surface down from the upper table surface. The grooves may be tapered from top to bottom such that the pins are frictionally bound in the deployed position in order to make the table stronger.

Abstract: A golf tee with tactile height adjustment includes a cup formed to receive and retain a golf ball. From the underside of the cup, a continuously threaded shaft extends and is formed with a longitudinal flat portion. A stop is formed with a threaded bore having threads complementary to those threads formed on the threaded shaft. Extending outward from the flat portions of the shaft are tactile engagement posts formed to engage the threads of the threaded stop as it threads along the threaded shaft. The engagement posts provide for the self cleaning of the threads of the golf tee, and also provides a tactile response including a distinct resistance to rotation of the threaded stop when the stop contacts the tactile posts. More specifically, when the threaded stop is positioned on the shaft adjacent a engagement post, the rotation of the stop is more difficult than rotation at a position on the shaft having no engagement post.
