20150205357 | CONTROLLING OUTPUT CURRENT FOR ELECTROSENSORY VIBRATION - 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. | 07-23-2015 |
