Abstract: Devices and methods for on-the-fly updates of circuit breakers during operation, the circuit breaker including a processor, a first memory including a first and second slot, and a second memory. In response to initialization, the processor stores a copy of a most recent firmware from the first or second slot in the second memory and executes the most recent firmware at the second memory. The firmware in the first or second slot may be a first firmware, and in response to obtaining a second firmware, the processor stores a copy of the second firmware in the other of the first and second slot. In response to a second initialization, the processor stores a copy of the second firmware from the other of the first slot and second slot in the second memory to enable execution of the second firmware, the second firmware being the most recent firmware.

Abstract: The present disclosure relates to an electric motor having a motor terminal box and a diagnostics-signaling unit, which is at least partly located within the motor terminal box. The diagnostics-signaling unit comprises a diagnostics device and an optical output unit. The diagnostics device that is configured to determine an operating condition of the electric motor and to provide an optical-output control signal indicative of the operating condition. Furthermore, the optical output unit that receives the optical-output control signal and that is configured to provide an optical output signal according to the optical-output control signal.

Abstract: A sensing device for monitoring an electrical component or apparatus is described. The sensing device is attachable to an electrical conductor and includes a sensor for measuring at least one physical property, a wireless communication unit for transmitting measurement data to a receiver, an energy harvesting unit configured to harvest energy from a current flowing through the electrical conductor and comprising an electromagnetic coil wound around a core, and a connection mechanism to make the core connectable to a strap comprising a material having a high magnetic permeability. The sensing device is configured to be operable when no strap is connected to the core and energy is harvested via an open magnetic circuit as well as when a strap is connected to the core and energy is harvested via a closed magnetic circuit.
