Abstract: A light engine for a floodlight includes a first subassembly for light emitting diodes (LEDs) and a second subassembly providing a housing for a driver. The first subassembly includes upper and lower mounting hinge arms at one side and the second subassembly includes upper and lower left hinge pins respectively extending from upper and lower left arms and upper and lower right hinge pins respectively extending from upper and lower right arms. The first subassembly can be mounted by the upper and lower mounting hinge arms on either side of the second subassembly, creating a reversible opening for access to the driver. The upper and lower mounting hinge arms can have a shape with respect to the hinge pins to provide a safety stopper. The lower mounting hinge arm can include a recess that catches against a lower arm to prevent automatically closing once in an open position.

Abstract: Several devices are disclosed that can be usable together or used in other valvetrains. Disclosed herein are a rocker arm assembly, compliance capsules for a switchable capsule of the rocker arm, actuators, and support structures for the actuators. The alternative compliance capsules can be electromechanically actuated by the alternative actuators, which are hung over the rocker shaft by the support structure. A cam actuator can be in addition to an overhead cam rail and in addition to the rocker shaft. The cam actuator can be configured with a compliance capsule so that the switching of the switchable capsule is mechanically linked and less reliant on precise electrical signal timing.

Abstract: Some embodiments are directed to a computer implemented system and method to determine relationships between data elements using a knowledge graph are described. The method comprises establishing a knowledge graph having graph elements, associating weights with data elements and determining at least some of these weights to be modifiable weights. Training data is used to determine the relationships between data elements in the knowledge graph by calculating the strength of the relationship. The calculated relationship strength values are compared to previously established relationship strength values, and one or more modifiable weights are modified to reduce the error between the calculated and established relationship strength values. These steps are repeated until a matching criterion is reached.

Abstract: An improved wire management arrangement for managing utility-connected conductors run to an electrical wiring device includes a connector and a housing. The connector receives the conductors and includes electrical contacts that connect to the conductors. The rear side of the housing is structured to be coupled to the connector, and the front side of the housing is structured to have an electrical wiring device faceplate installed so that the faceplate can connect to utility power through the connector. The connector includes latching elements, and the housing includes latch receiving openings that cooperate with the latching elements in order to couple the connector to the housing. The latch receiving openings obstruct the latching elements from unintentionally becoming de-installed during the Underwriters Lab (UL) 20 pull test.
