  • Publication number: 20250043982
    Abstract: A system for enabling scheduled ventilation of an area of interest (AOI) is disclosed. The system comprises a controller that is configured to receive first historical data and first real-time data associated with one or more of temperature, humidity, air quality, and occupancy within the AOI. The controller is further configured to receive second historical data and second real-time data associated with one or more of temperature, humidity, air quality, and weather attributes outside of the AOI. The controller accordingly determines a scheduled time and duration for ventilation of the AOI based on the received first and second historical data and the received first and second real-time data.

  • Publication number: 20240274288
    Abstract: Clinical information, molecular information and/or computer-generated morphometric information is used in a predictive model for predicting the occurrence of a medical condition. In an embodiment, a model predicts risk of prostate cancer progression in a patient, where the model is based on features including one or more (e.g., all) of preoperative PSA, dominant Gleason Grade, Gleason Score, at least one of a measurement of expression of AR in epithelial and stromal nuclei and a measurement of expression of Ki67-positive epithelial nuclei, a morphometric measurement of average edge length in the minimum spanning tree (MST) of epithelial nuclei, and a morphometric measurement of area of non-lumen associated epithelial cells relative to total tumor area. In some embodiments, the morphometric information is based on image analysis of tissue subject to multiplex immunofluorescence and may include characteristic(s) of a minimum spanning tree (MST) and/or a fractal dimension observed in the images.

  • Publication number: 20060086102
    Abstract: Apparatus and methods for improving the safety and efficiency and decreasing the cost of producing liquid oxygen with a small-scale use liquefaction device, according to various embodiments of the present invention. In one embodiment, a switch is electrically coupled to a storage dewar pressurizing means, the switch positioned to be activated by a portable dewar upon engagement of portable dewar with storage dewar. Cryocooler and/or cooling fan enter low power mode when dewar liquid level reaches a predetermined level, and to return to a fall power mode when dewar liquid level drops to another predetermined level. A cold finger of the cryocooler extends within the dewar and may prevent overfilling of the dewar. The cold finger has a temperature gradient. As the gas liquefies and fills the dewar, the liquid level rises only to a level on the cold finger at which the temperature exceeds the boiling point of oxygen.

  • Publication number: 20050045847
    Abstract: A totally open-totally closed valve leakproof shut off device, suitable for backflow prevention, to terminate fluid flow, which comprises a virtual or real keyway between aligned opposite flanges with central openings; said keyway having a lateral opening greater than the lateral dimension of said flange openings. A pair of seated annular seals on opposite sides of the keyway; extend slightly into the keyway to touch each other such that when no key is inserted, fluid flows without leakage; and when a segregable key is inserted into the keyway, it slides between the two seals and closes off the opening of the keyway in a leakproof manner. The device is adaptable for large valves by utilizing retaining means such as hasps and fingers to removably retain the key in place, and by disposing the key internally in a housing from which removal can be achieved by use of an actuator.
