Abstract: In electrosensory vibration technology, a potential difference is formed between a touched surface of a device and a body member of a user, creating an attractive force between the two. To meet industry safety standards, the capability of a corresponding voltage source to drive electrical current may be kept low, and the maximum slew rate with such a voltage source would be accordingly limited. However, such a limit on the slew rate may result in softer haptic effects or lower repetition rates of haptic effects, and the ability of such a device to express a wide range of haptic effects may be reduced compared to a device capable of driving the external load with the maximum current allowed by applicable standards. As a technical means to solve this technical problem, it may be helpful to use a powerful voltage source with a controller to control the outgoing current.

Abstract: A ballast for fluorescent tubes and the use thereof for producing fluorescent tube lighting fixtures using a novel gas excitation mode in which light is generated by means of controlled pulses leading to an increased power efficiency, with a data collection and transmission functionality, are disclosed.

Abstract: A discharge lamp lighting apparatus includes a capacitor, a charge circuit for charging the capacitor, a switching element, a gate driving circuit that controls ON and OFF states of the switching element, a simmer current supply circuit for passing simmer current through a discharge lamp, a starting circuit that impresses high voltage to a starting electrode, and an electric discharge sequence control circuit that generates the gate signal and the starting signal. When lighting the discharge lamp, a sequence of the gate signal corresponding to an alternating repetition of the ON and OFF states of the switching element is generated. Before outputting the starting signal, the switching element is ON as a stand-by state. Then the sequence starts when the starting signal is outputted.
