Abstract: Systems and methods for classifying product feedback by an electronic device are described. According to certain aspects, an electronic device may receive consumer feedback entries associated with various products, where each entry may include an initial classification. The electronic device may analyze each entry using a machine learning model to determine a subsequent classification for the entry. When there is a mismatch between classifications, the electronic device may present information associated with the entry for review by a user, where the user may specify a final classification for the entry, and the electronic device may update the machine learning model for use in subsequent analyses.

Abstract: Systems and methods for dynamically generating object models corresponding to regulations. According to certain aspects, a server computer may access a regulation and automatically generate a summary of the regulation based on a specific set of sentences. The server computer may additionally determine a set of topics and named-entity attributes for text within a regulation object model, as well as a probability that a topic or attribute is applicable to the regulation. Further, the server computer may generate and enrich object models according to the various analyses and avail the enriched object models for review by entities and users of regulatory compliance services.

Abstract: Systems and methods for dynamically determining potentially applicability of product regulation updates to product profiles. According to certain aspects, an electronic device may access new or updated product regulation updates for various jurisdictions as well as product profiles associated with certain products. The electronic device may employ various data analysis technologies to determine which product regulation updates are potentially applicable to which product profiles. The electronic device may present information associated with the data analyses, and enable users to review information, further assess applicability, make selections, and interface and integrate with external systems to exchange information and insights.

Abstract: 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.

Abstract: A high speed controllable load uses a voltage waveform synthesizer and a driver circuit to dynamically control an electronically variable load to generate a current though an arc fault circuit interrupter (AFCI) device under test. Sensors may be used to monitor a source voltage and the output current to generate an arbitrary waveform have a range of voltage and current phase shifts. An optical isolation circuit allows separation of grounds between a control stage and the AFCI device under test.

Abstract: A test apparatus for testing of a stop mechanism on a saw includes a support arm movable relative to a blade of the saw from a first position to a second position. The test apparatus also includes a simulation member coupled to the support arm. In the first position, the first end of the simulation member is offset from a portion of the blade of the saw, and in the second position, the first end of the simulation member is adapted to be in contact with the portion of the blade of the saw. The test apparatus further includes circuitry operatively connected to the simulation member to replicate an electrical property of a human finger such that contact between the blade and the first end of the simulation member triggers the stop mechanism of the saw.

Abstract: A camera testing apparatus includes a frame assembly, a control unit, and a plurality of first light sources and second light sources coupled to the frame assembly and in communication with the control unit. Each of the first and second light sources is in one of an illuminated first state or a non-illuminated second state, and each of the plurality of first and second light sources is adapted to be within a field of vision of a camera disposed remote from the first and second light sources. The control unit sends a first command to each of the first light sources to change a first operational parameter. The control unit sends a second command to a first one of the second light sources to illuminate at a first brightness and a third command to a second one of the second light sources to illuminate at a second brightness.

Abstract: 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.

Abstract: 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.
