Abstract: Systems and methods for detecting an occupancy of a room. The method comprises receiving, from a first door sensor associated with a door of the room, sensor readings indicative of an opening operation of the door. The method comprises determining, based on the sensor readings of the first door sensor, the occupancy status of the room to be a positive status. The method comprises receiving, from a second door sensor, sensor readings indicative of a closing and/or locking operation of the door. The method comprises determining whether the closing and/or locking operation has been performed. The method comprises upon determining that the closing and/or locking operation has been performed, validating the occupancy status of the room to be the positive status; and upon determining that the closing and/or locking operation has not been performed, triggering a supplemental detection process to detect the occupancy of the room.

Abstract: A dose feedback system provides real-time or near real-time intra-operative radiation dose feedback system to improve and/or ensure that a proper amount of radiation is delivered to a patient by, for example, carriers (e.g., tile carriers). The dose feedback system can be implemented during medical surgeries, operations, procedures, etc. The dose feedback system may allow a medical professional (e.g., surgeon) to more accurately achieve a prescribed radiation of a dosimetric intent or a more detailed dosimetric plan through adjustments to position, dose, quantity, etc. of carriers prior to terminating the medical procedure (e.g., cavity of tumor bed is closed and/or patient is brought out from under anesthesia) at which point adjusting the radiation dose may be difficult or impossible.

Abstract: A flooring accessory item, such as a transition, stair nosing, stair tread, floor vent cover, molding, or other accessories, is configured with an outer dry adhesive film layer to which a decorative surface skin layer can attach. The outer adhesive film layer is utilized to receive and secure a decorative layer for exposure at a later date. In some implementations, the film layer may be covered with a protective release paper to protect or preserve the outer adhesive, depending on the adhesive film type. The adhesive film layer can consist of a single layer of a dry adhesive film without a carrier, such as an internal scrim. Alternatively, the adhesive film layer may include a scrim-reinforced adhesive film, a woven fabric, foil carrier coated on both sides with an adhesive film, or an adhesive component that is chemically, thermally, or electronically (radio wave) activated at the installation site.

Abstract: A technique facilitates drilling operations by combining a conductor with a conductor sharing offset shoe system. The conductor sharing offset shoe system protects against collision of boreholes by properly positioning and/or orienting a drill string during drilling of boreholes through the conductor. The conductor sharing offset shoe system may comprise a bullnose disposed at a lower end of the shoe system and an upper guide member disposed at an upper end of the shoe system with a guide opening sized to receive the drill string therethrough. A guide tubing extends from the guide opening into the bullnose to guide the drill string during drilling of a borehole. The guide tubing is sized to preserve sufficient space for accommodating movement of the drill string through the conductor sharing offset shoe system externally of the guide tubing during drilling of another borehole.

Abstract: This document presents a system and method for gathering weather data and utilizing that weather data to calculation the upper and lower limits of the lightning formation range within a thunderstorm or storm system. The calculation may provide a probability for the beginning of lightning formation and lightning strikes for a geographic area for a given time period in sufficient time to permit alerts of lightning activity to be formulated and sent to users of the system. Equally, the system may calculate the probability of the cessation of lightning activity for a given geographic area at a specific time. The probability of both beginning and cessation of lightning activity may be provided at greater than 99% confidence.
