Active response gravity offload and method

A variable gravity field simulator can be utilized to provide three dimensional simulations for simulated gravity fields selectively ranging from Moon, Mars, and micro-gravity environments and / or other selectable gravity fields. The gravity field simulator utilizes a horizontally moveable carriage with a cable extending from a hoist. The cable can be attached to a load which experiences the effects of the simulated gravity environment. The load can be a human being or robot that makes movements that induce swinging of the cable whereby a horizontal control system reduces swinging energy. A vertical control system uses a non-linear feedback filter to remove noise from a load sensor that is in the same frequency range as signals from the load sensor.

Motion simulation chair

A motion simulation chair incorporates a base providing elevated attachment points for a number of support cables. A seat support is carried within the base and engages a seat for an occupant at a top end. The seat support has companion attachment points for the support cables at a bottom end. A control system incorporates a forward vertical control element constrained for three axis motion about a control point. A horizontal control element displaced upward from the control point and extending rearward from the forward vertical control element, engages the seat support. A control stick operated by the user imparts motion to the forward vertical control element about the control point. Moving the horizontal control element alters the suspension angles of the cables providing a corresponding tilt of the seat support and seat for realistic simulation of motion resulting from inputs to a computer game by the control stick.

Gate controlled floating well vertical MOSFET

A novel transistor structure for a DRAM cell includes two deep trenches, one trench including a vertical storage cell for storing the data and the second trench including a vertical control cell for controlling the p-well voltage, which, in effect, places part of the p-well in a floating condition thus decreasing the threshold voltage as compared to when the vertical pass transistor is in an off-state. This enables the transistor to exhibit increased gate overdrive and drive current during an active wordline voltage commonly applied to both gates of the storage and control cells.
