Abstract: According to the present invention there is provided an underwater inspection assembly (1,100) comprising, a first unmanned underwater vehicle (2) which comprises, at least a first propeller (3a), at least a first camera (4a), and at least a first optical transceiver (5a); a tether (7) a first end (7a) of which is connected to the first unmanned underwater vehicle; a docking station (21,121) which attached to the first unmanned underwater vehicle (2), and wherein the docking station (21,121) is configured to receive docking means (22, 122) mounted on at least a second unmanned underwater vehicle (12); at least a second unmanned underwater vehicle (12) comprising, at least a second propeller (3b) which can be operated independently of the first propeller (3a), at least a second camera (4b), and at least a second optical transceiver (5b), wherein said at least first and second optical transceivers (5a,5b) are configured to selectively optically communicate with one another; and a docking means (22, 122) which i

Abstract: A peripheral device for a computing system comprises an electrical switch and a user depressible button. An electrostatic brake is attached to the user depressible button and controls a force profile of the keystroke of the user depressible button. The button is coupled to and is configured to actuate the electrical switch at the end of the keystroke. A movable electrode is coupled to the depressible button and a stationary electrode is positioned parallel to and proximate the movable electrode. A dielectric material is positioned between the movable electrode and the stationary electrode forming an electrostatic brake. An electrical circuit is coupled to the first and the second electrodes and is configured to apply a voltage potential between the first and the second electrodes to apply a resistive force to the depressible button.
