Abstract: A rifle intelligence system includes a sensor module comprising an enclosure configured to be removably secured to a firearm; a processor disposed within the module enclosure; and a plurality of sensors disposed within the module enclosure and communicatively coupled to the processor. The plurality of sensors is configured to generate shot attribute data associated with operation of the firearm and to wirelessly transmit the shot attribute data to a mobile computing device. The shot attribute data includes at least acceleration of the firearm along a bore axis and a temperature measurement of the barrel of the firearm.

Abstract: A brush holder assembly for an electrical motor includes a brush box including a main body and a cover portion, the main body with a cavity and including a set of first arms extending in opposition from the main body. The cover portion includes a set of second arms extending in opposition from the cover portion, and a set of projections extending in opposition to one another from the cover portion. Each of the set of first arms and a respective one of the set of second arms define a channel therebetween sized to receive a portion of a sleeve of the electric motor. The assembly also includes a cover that is coupled to the cover portion of the brush box, a brush located in the cavity of the brush box, and a spring positioned against the brush to force the brush towards a commutator of the electric motor.

Abstract: An electrical motor includes a sleeve, a rotational assembly located in the sleeve, and a shaft rotatably mounted about an axis extending longitudinally through the sleeve. The motor also includes an endcap, and a brake mechanism located about the axis of the shaft, the brake mechanism including a spring and a first bushing, wherein the spring forces the first bushing against the endcap to create a static frictional torque between the first bushing and the endcap when the motor is in an off state.

Abstract: A containment system includes a vapor resistant container for a material, and a seal for the vapor resistant container.
