Abstract: This application relates to a building energy analysis and management system for measurement and verification of building performance. The system can analyze, optimize, manage, maintain, trouble shoot, and/or modify building systems, such as HVAC systems, in connection with the building energy usage. Measurements may be gathered for one or more HVAC units coupled to pressure independent valves, and sent to one or more Surge Panels that pass data to remote analysis servers, which can receive other system or external data. The analysis servers compare measurements to predicted values and can standardize the predicted values to account for external conditions. The comparison can result in difference values used to generate probable causes and optimization recommendations. The system outputs reports or other data display using a graphical user interface that can be adjusted for an anticipated user.

Abstract: The invention relates to one or more aptamers isolated against the SARS-CoV-2 spike protein and methods of using the same. Certain embodiments of the invention relate to methods of detecting the presence, absence or amount of SARS-CoV-2 in a sample using the one or more aptamers described herein. In certain embodiments, the invention relates to one or more aptamers that are capable of specifically binding to SARS-CoV-2 proteins, including aptamers that are capable of specifically binding to the S1 subunit (including the receptor binding domain (RBD)) and/or the S2 subunit within their native conformation as part of the SARS-CoV-2 spike protein in its trimeric form or as separate monomers.

Abstract: A semiconductor processing apparatus includes a reaction chamber, a movable susceptor, a movement element, and a control system. The reaction chamber includes a baseplate. The baseplate includes an opening. The movable susceptor is configured to hold a workpiece. The movable element is configured to move a workpiece held on the susceptor towards the opening of the baseplate. The control system is configured to space the susceptor from the baseplate by an unsealed gap during processing of a workpiece in the reaction chamber. Purge gases may flow through the gap into the reaction chamber. Methods of maintaining the gap during processing include calibrating the height of pads and capacitance measurements when the susceptor is spaced from the baseplate.

Abstract: In one embodiment, the present invention is a camera calibration tool. One embodiment of a three-dimensional test target for calibrating an image capturing device includes a first planar face exhibiting a first color, a second planar face exhibiting a two-toned pattern of a second color and a third color, and a third planar face exhibiting the two-toned pattern of the second color and the third color, wherein the first planar face, the second planar face, and the third planar face meet at a first right-angle convex vertex.

Abstract: An automatic grocery bag opener automatically opens plastic and polyethylene bags with forced air in produce departments and at checkout counters of grocery stores. Bags are held in position from any of several different types of hangers on the front of the enclosure. The outside bag is forced and held open by the forced airstream from the air supply. The bag can then be filled with the grocery items. Once the bag is filled, it is removed from the hangers and the next bag is automatically blown and held open. As long as the motion sensor sees movement, the blower stays on. If no movement is seen by the motion sensor, the motion sensor ends an electric signal, thus turning off the blower. In turn, if the motion sensor sees a motion, an electric signal is sent to the blower and turns the bagger back on.
