Abstract: A self-adapting soft-starter device includes an electric current limiter limiting electric current supplied to the motor to a preset maximum current limit, a ramp-up time determiner determining the actual ramp-up time of the electric motor, a storing device storing a preset minimum ramp-up time, a comparator comparing the determined actual ramp-up time with the preset reference ramp-up time, a replacing device replacing the preset maximum current limit with an auto-adapted current limit based upon the outcome of the comparison between the determined actual ramp-up time and the preset reference ramp-up time. The soft-starter automatically optimizes the maximum current limit driven by the motor to match its load requirements which is useful to cater for load variations with time during the lifetime of the product in the application by avoiding the need for human intervention to change the soft-starter settings. Wear and tear is also reduced, extending motor lifetime.

Abstract: Control apparatus 1 for photovoltaic modules 3 which can be connected to one or more photovoltaic modules 3. The control apparatus is able to check for the proper working of the solar modules, and also to collect all electrical data like voltage, current, power, energy in order to calculate also the efficiency of the plant. Up to 16 modules can be used (including a master controller, temperature measurement modules, output modules, input modules) and they are interconnected by using a bus system which does not require any wire. A base level consist of one master controller module and one or more input modules. An extended system includes also additional modules, like measurement of temperatures or relay outputs.

Abstract: The invention refers to a digital camera 1 which can be used in a motion sensor 4. In order to be able to test the function of the camera, a light source 3 is provided which irradiates at least a part of the sensing matrix 2. The processor device 5 of the camera judges whether the output signal of the sensing matrix 2 corresponds correctly to the light which has irradiated the sensing matrix 2. Various test methods are disclosed, such as using varying wavelengths, ON/OFF-modulation, dependence on shutter time and illumination of various regions of the sensing matrix 2.
