Abstract: An electronic system for a firearm includes a power source, one or more electrical conductors electrically connected to receive power from the power source, and a plurality of electronic devices. Each electronic device has an electrical input configured to receive power from the one or more electrical conductors to power the electronic device. A communication device is configured for data communication across the one or more electrical conductors. A method of communicating between electronic devices connected to a firearm includes powering a plurality of electronic devices connected to a firearm from a power source through one or more electrical conductors, and communicating data between the plurality of electronic devices across the one or more electrical conductors.

Abstract: A power system for a firearm includes a buffer tube adapter that attaches to a buffer tube of the firearm. A buttstock slidably engages with the buffer tube adapter along an axis, and the buttstock is adapted to adjust a length of the firearm. A power source is held by the buffer tube adapter and is at least partially covered by the buttstock. The power source is configured to power electronic accessories mounted to the firearm. The power system is mountable to the firearm without altering the buffer tube of the firearm.

Abstract: A cooking appliance, system, and method use one or more split-surface-area radiative heating elements and may also use one or more additional heating elements, such as microwave and convection heating elements, to heat or cook food. The radiative heating elements are used in a cooking chamber having an improved geometry. A controller includes features to adaptively learn and adjust cooking recipes based on modifications and user ratings of a particular cooking recipe or based on learning in response to analysis of modifications and user ratings of plural cooking recipes. The controller may learn from ratings of other users of similar cooking appliances via a network connection.
