Abstract: The present disclosure relates to arc fault detection in an electrical switch apparatus. In aspects of the present disclosure, an arc fault electrical switch apparatus includes a conductive path, a switch configured to interrupt electrical current in the conductive path, a current sensor in electrical communication with the conductive path and configured to measure the electrical current to provide current measurements, and a controller. The controller is configured to execute instructions to sample the current measurements to provide current samples, computing an estimated signal-to-noise ratio of the electrical current based on at least a portion of the current samples, determine whether the signal-to-noise ratio is less than a predetermined threshold, and activate the switch to interrupt the electrical current in the conductive path, if the signal-to-noise ratio is less than the predetermined threshold.

Abstract: Various systems, methods, and computer program products for responding to service requests and facilitating communication between relevant parties are provided. The system may receive a request from a user, obtain a user location, identify a service provider such as an emergency response center based on the location, facilitate coordination of response efforts, and provide a page that is shared between various parties such as the user, contacts of the user, an operator, and a responder. The various parties may provide to the system inputs such as video to capture what is currently happening. The page may be updated with the inputs, include a status of the service request such as whether responders have been dispatched, and include a current location of the responders and other users. Using the page, various parties may obtain real-time situational awareness of an event that culminated in the service request and communicate with other users.

Abstract: A kit for the assembly of a mosaic structure containing an assembly tool to place blocks having various colors onto at least two interlocking core pieces. The blocks adhere to the interlocking core pieces or to each other by pressure sensitive adhesive, or alternatively, by magnetic attraction. After the blocks are placed, the interlocking core pieces are secured by engagement such as a twist-lock connection.

Abstract: The invention relates providing an event-based connectivity platform that creates and communicates shared pages based on location and other information obtained from devices that automatically provide the location and other information. A system may include a page server that creates an event-centric shared page responsive to a single button press or other indication. Once created, the page server may invite other users to access the shared page. User devices that have access to the shared page, including the user device that cause the shared page to be created and/or other user devices, may automatically provide updates to the page server. The devices may automatically provide the updates at various times without intervention by the user. The automatically provided updates may include location information. Users may also provide other information such as image, audio, and text for updating the event-centric shared page.

Abstract: A method is disclosed for predicting a pulse periodicity in a signal. The method includes the steps of receiving a signal that includes a component that is periodic having an unknown periodicity and a noise component; comparing the signal to an adjustable reference signal, and varying at least one of the phase and the periodicity of the reference signal until a best fit match is obtained between the signal and the reference signal.

Abstract: A kit by which a fabric mosaic may be assembled comprising a template, fabric pieces, and stylus. The fabric pieces are secured to the template by inserting portions of the fabric pieces into opening where they are secured by an interference fit.

Abstract: An art kit having a template, preferably with a pre-printed design defined by specifically positioned squares and a plurality of polygonal monochromatic tiles of various colors is provided. The pre-printed design has a numerical grid formed thereon which corresponds to a legend for positioning particular colors of tiles in particular locations to complete the intended artwork. This artwork can be framed and hung when completed. Optionally, the template may be formed of transparent material for backlighting purposes, have a hole pattern to accommodate positioning of lamps in a particular array, or be formed on an item of clothing and made permanent through the application of heat.
