Abstract: A hand held machine tool for machining workpieces, comprising a housing in which a motor driving a rotor shaft is accommodated, and having an air guide region formed in the housing for supplying cooling air to the motor along a main flow direction oriented substantially parallel to the motor longitudinal axis. The air guidance region is limited at one end by at least one air inlet and at the other end by at least one air outlet for discharging the cooling air from the housing. A separator is arranged in the air guide region for dividing the cooling air into an outer partial air flow flowing around the outer circumference of the motor and into an inner partial air flow flowing through the motor. The separator is formed such that a degree of contamination of the outer partial air flow is greater than a degree of contamination of the inner partial air flow.

Abstract: A system provides power and data to solid-state lights or other stage effects devices. A power hub receives the data as an input signal and includes output ports each with data conductors and power conductor pairs. The hub includes a buffer circuit, a power distribution circuit, and sensor circuits. The buffer circuit distributes data to the output ports. The power distribution circuit receives an input voltage and distributes a calibrated output voltage and maximum current to each output port. The sensor circuits are connected to a respective output port and detect connection of devices and a maximum required power at each output port. The power distribution circuit individually increases voltage to each output port at a calibrated ramp rate based on the maximum required power. The interface circuit connects the data conductors and the power conductor pairs to the devices and passes the voltage/power and data thereto.
