A control system may include a processor that may receive a first dataset associated with power properties of a rotating load device coupled to a relay device. The processor may also determine frequency properties based on the power properties and determine a switching profile to control moving a first armature of three armatures in the relay device based on the frequency properties. The switching profile is configured to control movement of the first armature between a first position and a second position, and wherein the switching profile comprises a firing angle for moving the first armature with respect to an electrical waveform, a second armature, and a third armature. The processor may then control a current provided to a relay coil of the relay device based on the switching profile, such that the relay coil causes the first armature to move.

A system, device and method are provided for continuously generating more than 0.01 watt of electrical energy by harnessing mechanical or kinetic energy from a reciprocating motion of a user's torso during breathing. The reciprocating motion causes reciprocating lateral and medial translation of two chambers of the device housing. That reciprocating lateral and medial translation rotates a gear, which in turn, drives a dynamo to produce electrical energy. Since the conversion from the mechanical energy of the spinning rod to power is direct, the energy-conversion efficiency may be up to 90% or higher. The device may further comprise one or more charging means for providing electrical energy to one or more peripheral electronic devices. In some embodiments, additional integrated functions may include auxiliary energy storage, backup energy, emergency power, mini-MP3 player, data recorder, GPS interface, miniature video recorder, speaker, abdomen muscle exercise, timing, Bluetooth interface, and heath information analyzer.

The present disclosure includes drive modules for motor-drive assemblies of an industrial automation system. The drive modules may include a housing having a cavity and may also include power circuitry and control circuitry. The power circuitry may convert input DC power to three-phase controlled frequency AC power and may supply the three-phase controlled frequency AC power to a motor. The control circuitry may apply control signals to control operation of the motor. The drive module may also include an adapter that couples to a first end of the housing and couples the housing to the motor. The adapter may be removable and sized according to a frame size of the motor such that the drive module is compatible with the motor. The housing may be independent of the frame size of the motor. As such, the housing may be interchangeable for any motor frame size and/or motor power.

A device for cleaning a handle, includes a handle including a gripping surface to be disinfected, an application member for applying a cleaning liquid to the gripping surface, and cleaning liquid supply including at least one reservoir for receiving cleaning liquid and distributing it to the application member. The application member includes at least one buffer reserve arranged in contact with the gripping surface. The device includes a unit for actuating the application member, including a driver configured to move the buffer reserve and/or the gripping surface relatively with respect to one another so as to apply cleaning liquid to substantially the entire gripping surface during this movement.

The invention relates to a device for reducing harmful bearing voltages in an electrical machine (M) fed by a DC link voltage of a DC link, said electrical machine comprising a stator (3), which has windings (7) and is insulated from ground (GND), and a rotor (2) and a motor shaft, wherein furthermore a rotor-side bearing (LA.sub.R) and a stator-side bearing (LA.sub.S) are each insulated from the ground (GND) and the rotor (2) and the stator (3) are electrically connected to each other by means of a bypass capacitance (C.sub.Bypass) having a predefined capacitance.

Systems and methods of the inventive subject matter are directed to control systems that create virtual mass in a haptic feedback system. Embodiments include a jog knob coupled with a PCB stator motor such that the PCB stator motor can be controlled to give the jog knob a feeling of mass that is different from its actual mass. Thus, a system of the inventive subject matter can be configured to continue a rotation as if it has a higher mass than it actually has, resulting in smoother rotations that last longer. This functionality can be useful to, for example, remotely control a camera's movements while still giving a user the feel of a comparable mechanical system.

A device supplies energy to a sensor arrangement in a rail vehicle. The device has a housing in which there is arranged a coil which can be inductively coupled to a motor cable carrying an alternating current. The housing is embodied to enclose part of a length of the motor cable, and the coil is wound around an annular coil core which concentrically or substantially concentrically surrounds the motor cable. The housing has multiple parts including at least one first and one second housing part. The annular coil core is implemented in multiple parts and a first coil core part is arranged in the first housing part and a second coil core part is arranged in the second housing part. The housing is further embodied to mechanically secure the motor cable to a component of the rail vehicle and/or to mechanically connect the motor cable to a further motor cable.
