In this functional model of an original electromechanical power steering the componentsare exposed within the steering housing in order to demonstrate for example the operation of the double drive pinion. The system has a controlpanel with emergency stop switch, ignition switch, indicator light and OBDinterface. The power supply is provided by a vehicle battery. Optional errorcircuit 6 switches / 12 errors and associated test sockets in 4mm design. Because of the extremely high forces onall moving parts and rotating the open areas were fitted with transparentcovers for safety. More represent able functions are active reset in thedirectional stability as well as the controlled demand for power consumptionfor reduction in fuel consumption. Steering angle, powerconsumption and torque can be tested and measured using standard workshop diagnostic systems via the OBD interface. The communication between the controlunit for steering column electronics, the diagnostic interface (gateway) andthe Diagnostic Interface (OBD) is done via CAN Bus. Thus, the required effort withand without assistance can be represented visually. In order to increase the steering forcespartially, a resistance pressure box is mounted.

A non-sterile medium designed to be applied to a patient's unbroken skin surface to provide a coupling between an analytical device (e.g., ultrasound transducer, optical glucose monitoring system) and the patient, allowing for the emission and reception of signals (e.g., ultrasound, light) that pass through the skin during an examination. It may be used by a healthcare professional or layperson. After application, this device cannot be reused. It is in the form of a non-sticky, fluid-like gel that may also assists the operator's ability to move the analytical device smoothly over the skin to better analyse the site of interest.

The Synchronous Machine is designed to operate as a motor or as an alternator. The rotor works as a square cage when starting and stopping. The three-stator windings are brought out to 4-mm separated terminals on the housing, so that they may be connected in wye or delta. The Synchronous Machine runs at constant speed independently of the load. The synchronous speed directly depends on the current frequency and on the number of motor poles. The trainer is also provided with supply terminals, a rheostat for control over the excitation current and a protective circuit breaker in the rotor circuit. Specifications and/or diagrams are silk-screened on the back of a clear-plastic front panel for ease of identification. The main characteristic of a Synchronous Machine is the possibility to change the power factor. Its stator is connected to an AC power supply and its rotor must be linked to a AC/DC rectifying unit. The trainer is protected by a either a diode or thermal-magnetic circuit breaker. Included in the Rotating Machines Trainer for 1/3 hp - 250 W. Requires a 120V 60Hz circuit.

The main winding, the auxiliary winding and the centrifugal switch provide separate 4 mm terminals on the housing. Specifications and/or diagrams are silk-screened on the back of a clear-plastic front panel for ease of identification. The Split Phase Induction Motor 60 HZ trainer is designed to teach the principles of the auxiliary resistive phase motor or split phase motor. Starting current is about 4 at 6 times the nominal current. This motor works like a capacitor start motor at its normal operation speed. The auxiliary winding is made of thin wire. We recommends opening it after a few seconds. The trainer is protected by a either a diode or thermal-magnetic circuit breaker. Requires a 120V 60Hz circuit. This kind of motor is needed for low power, low inertia and low starting frequency applications. In this type of motor, there is no capacitor. The phase shift needed to start the motor origins from the windings resistive and inductive properties.
