Abstract: A paint sprayer may include a housing enclosing an internal space. A paint sprayer may include a nozzle assembly coupled to the housing. A paint sprayer may include a pump assembly fluidly coupled to the nozzle assembly and positioned within a first region of the internal space. A paint sprayer may include a reservoir fluidly coupled to the pump assembly and configured to hold a spray liquid, the reservoir being positioned within a second region of the internal space.

Abstract: A system for managing a power tool includes a tool implement and a tool base releasably attachable to the tool implement. The tool implement includes a working end, a memory storing an information parameter, and an electronic processor configures to transmit the information parameter. The tool base includes a base housing, an electric motor, a rotatable output shaft coupled to the electric motor, an electrical interface coupled to the electronic processor, and a controller including a first and second electronic processor. Through the electrical interface, the controller is configured to receive the information parameter, by the first and second processors, as first and second data, determine whether the first data and the second data agree, and enable a function of the motor of the tool base in response to determining that the first data and the second data agree.
