  • Publication number: 20190238083
    Abstract: A battery-powered motor may include an electric motor, a controller, and a housing. The electric motor may be wound to enable the battery-powered motor to achieve a non-limited motor maximum motor revolutions per minute (RPM) for at least one specified battery. The controlling current may include limiting current to the electric motor at lower RPMs, and limiting the current to prevent the RPM of the electric motor from exceeding a limited maximum motor RPM which is lower than the non-limited motor maximum RPM. The housing may enclose the electric motor and the controller and the specified battery. The housing may have a form factor to engage with a machine that engages with an internal combustion engine that has a maximum engine RPM that is approximately the same as the limited maximum motor RPM.

  • Publication number: 20190237715
    Abstract: When providing alternating current (AC) power to operate AC powered devices such as power tools (such as drills, table saws, miter saws), equipment (such as lawn mowers), and consumer products (such as refrigerators, television, lights) without being tied to a fixed utility power supply typically requires a generator (such as an internal combustion engine based generator) or a battery powered inverter. In order to meet power and runtime needs for these devices, a battery powered inverter must be relatively large and expensive. This simple fact prohibits their use in many environments.

  • Publication number: 20190208292
    Abstract: A system for remotely retrieving sensed conditions at one or more building components. The building components are remote or numerous so that a wireless collection of the sensed conditions provides a significant benefit to a builder or building operator. A remote transceiver sends a wireless signal to a building component. The building component includes an onboard transceiver. At least some of the energy from the transmitted wireless signal is received by the onboard transceiver, sent to a storage device, and stored therein. The stored energy is used to operate a sensor for sensing an onboard condition. The onboard condition is then wirelessly transmitted by the onboard transceiver back to the remote transceiver to be displayed.
