Abstract: The motion of a member such as a simulator plane and a "virtual reality" cabin, or a vehicle, is controlled by apparatus comprising one or more preferably electromagnetic actuators disposed between the member and a ground level, and a control arrangement for providing signals to the actuator whereby to cause the actuators to generate thrust.  In order to allow the motion of the member to be influenced by factors such as the movement  of a user on the simulator plane, or the detection of other  movements,  the apparatus further comprises means for monitoring characteristics of the relative positions or movements of the member and the ground level, or the forces between the ground level, the actuator and the member, and providing signals indicative of said characteristics. The control arrangement  is responsive to signals provided by the monitoring means and comprises means for generating or modifying the control signals to be provided to the actuator.              By controlling the motion of a member in this way, it is  possible  to make  motion systems such as "virtual reality" system more convincing.  It is also possible to construct stabilizing systems such as active suspension  systems for vehicle.

Title: In-line skate braking system
Inventor: PALLADINO MICHELE
IPC: A63C17/14
Filed: 1996-10-11
Abstract: An improvement to the sporting equipment of in-line skates. The braking system is designed so that all the wheels of the skate are in contact with the ground and that the braking action is manually applied to the wheels. The generic in-line skate has several elements such as a boot and a lower chassis that mount the wheels in series. The standard brake is a friction pad on the lower chassis extension. The structure of this improvement includes three distinct elements, the manual brake actuator, the braking mechanism and a modified lower chassis that accommodates the braking mechanism.  The manual brake actuator operates similarly to a bicycle braking system; utilizing levers and cables. As the levers of the manual brake actuator are closed, the wire insert of the cable is moved resulting in engagement of the braking mechanism. This braking mechanism is configured for the two most popular types of braking configurations: the disc pincer type and the drum and shoe type.
