Abstract: Methods, systems, and computer-readable media for generating a statistically covaried machine learning model for performance measurement of service providers. The method receives a configuration file that includes one or more parameters associated with a plurality of individuals and parses it to generate and executing the database query on input data to generate sets of tabulated data of individuals of the plurality of individuals. The method next determines one or more measures of service providers listed in the configuration file using two or more tabulated data of individuals from the sets of tabulated data of individuals. The method finally generates a covaried machine learning model by training a machine learning model by statistically covarying measures and using them as training data.

Abstract: A smoke detector and method for testing a smoke detector are provided. The smoke detector includes a housing defining a chamber, an emitter, and a receiver. The housing includes an inlet port and an outlet port configured to allow an airflow to pass through the chamber. The emitter is configured to emit light into the chamber. The receiver is configured to receive light reflected by ambient materials in the airflow passing through the chamber. The smoke detector includes an entry point and an exit point, defining a channel therebetween. At least a portion of the airflow passes through the channel. The channel is in fluid communication with a sensor. The sensor is configured to detect at least one of a pressure differential and a mass flow of the airflow. The smoke detector and method for testing the smoke detector enable in situ testing of the smoke detector.

Abstract: A detector assembly for a duct of a heating ventilation and air conditioning system includes an outer housing having at least one through hole formed therein, an inner sampling support receivable within a hollow interior of the outer housing, and at least one detector mounted to the inner sampling support. The at least one detector is axially aligned with the at least one through hole when the inner sampling support is installed within the hollow interior of the outer housing. The at least one detector is operable to sample air within the duct to detect a hazardous condition.

Abstract: A pickup comprises a mounting component having a mounting plate, a first contact and a second contact. The pickup also has a coil component including a primary flatwork member, a secondary flatwork member, a pole therebetween, and a coil of wire wrapped around the pole. A magnet cooperates with the pole. A first coil end is electrically connected to a first coil component contact, and a second coil end is electrically connected to a second coil component contact. When assembled, the first coil component contact electrically couples to a select one of the first contact and the second contact of the mounting member regardless of the orientation of the coil component relative to the mounting plate.

Abstract: A pickup for a musical instrument includes a first assembly, a housing, and a magnet. The first assembly comprises a base plate, a pole that extends from the base plate, and a coil of wire wrapped around the pole. A first lead wire extends from a first coil end and a second lead wire extends from a second coil end. The housing is user attachable to, and detachable from, the top of the first assembly, independently of any electrical connections made to electronics of the musical instrument. Moreover, the housing attaches to and detaches from the first assembly such that when attached, the pole of the first assembly is in magnetic cooperation with the magnet. Also, the housing is removable, thus allowing the magnet to be changed out to another magnet without removing strings or other hardware of the musical instrument.

Abstract: A pickup for an electrical, stringed musical instrument includes a first assembly and a second assembly. The first assembly includes a base plate, a pole that extends upward from the base plate and a coil of wire wrapped around the pole above the base plate. The second assembly includes a housing that has a fastening feature that allows the second assembly to be user attachable and detachable from the first assembly independently of any electrical connections made by the first assembly. The second assembly also includes a magnet seated within the housing. The pickup is further constructed so that the second assembly readily attaches and detaches to the first assembly such that when attached, the pole of the first assembly is in magnetic cooperation with the magnet of the second assembly.

Abstract: A ground fault detection scheme uniquely incorporated within a distributed intelligence, fire alarm and detection system, such that detection is achieved with location identification. The modules (and transponders) of the system collaborate with the loop controller in performing ground fault operations to determine precise existing ground conditions at the module locations.
