Abrégé

Systems and methods for maintaining indoor air quality are disclosed. According to embodiments, air quality data measurements and associated dates/times may be received from smart sensors associated with an indoor space. Based on the air quality data detected by the smart sensors, a predictive air quality model for the indoor space may be generated, e.g., by plotting a time series for the air quality data and deriving a linear progression based on the plotted time series. A future time when the air quality for the indoor space will reach a threshold air quality level, above which an allergic or asthmatic reaction may occur in a user, may be predicted using the predictive air quality model. An indication may be displayed notifying a user that an air filter associated with the indoor space should be replaced at or before the predicted future time to prevent an allergic or asthmatic reaction.

Abrégé

A device for applying a force to a planar surface includes a tub, a cavity, a membrane, and an opening. The tub includes a bottom wall, at least one sidewall, and a cavity defined between the bottom and sidewalls. The membrane is disposed within the cavity and a perimeter edge of the membrane is fixed to the tub. The opening is formed in the tub and adapted to receive a pressurized fluid to fill a portion of the cavity below the membrane to displace at least a portion of the membrane away from the bottom wall to apply a force to the planar surface.

Abrégé

A light meter for measuring photometric quantities includes a telephotometer having a photo detector to receive light energy entering the telephotometer. A light metering valve, for the purpose of providing a variable field of view, is located in the body of the telephotometer generally at the focal plane of the objective lens of the telephotometer. A controller, which includes a digital processor in communication with the photo detector will process information from the photo detector and from a range finder included in the system to output light intensity of a target light source.

Abrégé

The invention relates to a method and a device for testing the fire hazard of a material. According to one embodiment of the method, a plane region of the surface of a specimen made of the material is brought in contact for at most a predetermined contact time with a glow wire, which has been heated to a predetermined temperature. Image data of the specimen are furthermore acquired by at least a first camera at least while the specimen is in contact with the glow wire. Image processing of the acquired image data of the specimen is furthermore carried out, preferably in realtime, ignition of the specimen by the glow wire being detected if applicable. A first duration is then determined, which corresponds to the length of time between the application of the tip of the glow wire on the specimen and the ignition of the specimen. Furthermore, according to one embodiment of the invention, a second duration may if applicable be determined by means of the image processing of the acquired image data of the specimen, the second duration corresponding to the length of time between the application of the tip of the glow wire on the specimen and the end of the ignition of the specimen. The method and the device are suitable in particular for carrying out tests to assess the fire hazard of materials according to the standards EN 60695-2-10, -12 and -13.

Abrégé

The image data capture of a test piece is performed with at least one first camera. A reference point of the test piece is determined by processing the image data recorded with the at least one first camera. A burner is positioned at a prescribed first distance from the reference point for the flame exposure of the test piece. At least one second camera may also detect whether the test piece exposed to a flame is burning or incandescing. At least one third camera may be used for monitoring the burner flame and at least one fourth camera may be used for determining whether the test piece drips while burning. Furthermore, at least one detector may used for detecting whether the drips ignite a pad of wadding positioned under the test piece.
