  • Publication number: 20210105881
    Abstract: An approach for controlling ultraviolet intensity over a surface of a light sensitive object is described. Aspects involve using ultraviolet radiation with a wavelength range that includes ultraviolet-A and ultraviolet-B radiation to irradiate the surface. Light sensors measure light intensity at the surface, wherein each sensor measures light intensity in a wavelength range that corresponds to a wavelength range emitted from at least one of the sources. A controller controls the light intensity over the surface by adjusting the power of the sources as a function of the light intensity measurements. The controller uses the light intensity measurements to determine whether each source is illuminating the surface with an intensity that is within an acceptable variation with a predetermined intensity value targeted for the surface. The controller adjusts the power of the sources as a function of the variation to ensure an optimal distribution of light intensity over the surface.

  • Patent number: 10962625
    Abstract: In a method of determining the position of an object, raw image data of the sky is recorded using a celestial imaging unit. The last known position, orientation, date, and time data of the object are obtained, and the position of a celestial body is measured. A latitude and longitude of the object is determined by matching the measured celestial body position to the expected celestial body position based on the input parameters. A system for determining a new position of an object comprises a celestial imaging unit configured to record image data of the sky, a signal processing unit, and a signal processing unit configured to receive and store in memory the image data received from the celestial imaging unit. The signal processing unit filters the image to find the positions of celestial objects in the sky. The signal processing unit is further configured to use roll and pitch from an IMU, and date and time from a clock to determine the object's position (latitude and longitude).

  • Patent number: 10948379
    Abstract: Systems and methods for sensing water device run time, transmitting this data via a network to a database which analyzes, records and reports the individual run times and the aggregate use over any given timeframe. Sensors used to measure device use time do not directly measure flow rate, and may sense device run time by sensing water flow, through electronic signals, vibration, etc. The sensors may be battery powered and transmit discrete data packets via radio frequency to powered node units. A system of node units communicates with a central internet gateway which uploads the data packets to a cloud-based database which organizes, analyzes, stores and reports the information. The system allocates the cost of water flowing through a common water meter to a plurality of individual units within a collection of geographically proximate units. The systems are useful in multi-unit buildings or complexes having stacked plumbing.
