A method and apparatus for providing an Aircraft Emergency Safety Control System (AESCS) capable of regaining control of an aircraft that may have been lost due to incapacitation of the crew includes an airborne segment, a ground segment, and a communications segment wherein control of the aircraft is removed from the control of unauthorized person(s) onboard the aircraft, and the aircraft is directed to a destination that is considered a safe location for the aircraft given it's status, and to facilitate a reasonably safe emergency landing.

The invention concerns a system for generating basis for decisions concerning the behavior of a vehicle and/or of a driver of a vehicle. The system comprises a supervising unit (10) which comprises at least one storage member (12). In the storage member (12) there is a set of rules (14) of a particular kind for how the driver of the vehicle and/or the vehicle shall behave in different situations. The system also comprises a user interface (16) and adaptation means (13) arranged to adapt said set of rules such that at least some of the rules (14) with conclusions (24) belonging thereto are suited to form the basis for decisions concerning the behavior of a vehicle and/or of a driver of a vehicle. The invention also concerns a vehicle and a method of generating basis for decisions concerning the behavior of a vehicle and/or of a driver of a vehicle.

A control system utilizes hydraulic power only to control a fixed-wing aircraft horizontal stabilizer trim control surface with no electrical control devices except for a cockpit pilot/co-pilot initiated 3-position spring-centered toggle trim switch, a backup electrical motor and a standard electronic logic pilot interface. The toggle trim switch controls two solenoid valves which control the operation of a directional control valve. The control system also includes a hydraulic motor, a rate control valve, a blocking-bypass valve, a shutoff valve with an integrated position sensor and a gear set driving an acme threaded output shaft for elevating or lowering the horizontal stabilizer trim control surface on command by the pilot. The control system controls the horizontal stabilizer trim control surface angular displacement rate as a function of angular position by means of a mechanical feedback linkage between the spool of the rate control valve and the horizontal stabilizer trim control surface. The sleeve of the rate control valve has a variable outflow area slot to control the hydraulic flow rate to the motor ports of the hydraulic motor. The horizontal stabilizer trim control surface is automatically stopped at pre-determined maximum-up/maximum-down positions by means of a mechanical feedback linkage between the horizontal stabilizer trim control surface and the spool of the shutoff valve. If the mechanical feedback linkage between the rate control valve spool and the horizontal stabilizer trim control surface malfunctions, the rate control valve automatically reverts to a default fixed flow rate which translates into a corresponding fixed horizontal stabilizer trim control surface angular displacement rate.

The present invention relates to a system for the yaw control of an aircraft fitted with a plurality of engines, the system (SC) comprising in particular a computation unit (16) formulating a command dr for yaw control, dr=Ka.&PHgr;c+Kb.p+Kc.&PHgr;+Kd.r+Ke.&bgr;, on the basis of the controlled roll attitude &PHgr;c, of the roll rate p, of the effective roll attitude &PHgr;, of the yaw rate r, of the sideslip &bgr; and of gains Ka, Kb, Kc, Kd and Ke which are fixed by a device (28). According to the invention, the system (SC) comprises a a device (30) for detecting any fault with an engine of the aircraft, and the device (28) is formed in such a way as to modify the values of the gains Ka, Kd and Ke relating respectively to the controlled roll attitude &PHgr;c, to the yaw rate r and to the sideslip &bgr;, upon the detection by the device (30) of a fault with an engine of the aircraft.

A surgical method and a control system is provided. The surgical method and the control system can advantageously be used in a minimally invasive surgical apparatus. The method includes generating a desired surgical instrument movement command signal. It further includes comparing the desired surgical instrument movement command signal with at least one preset surgical instrument movement limitation. Should the desired surgical instrument command signal transgress the preset surgical instrument movement limitation, the desired surgical instrument movement command signal is restricted to yield a restricted surgical instrument movement command signal. A surgical instrument is then caused to move in response to the restricted surgical instrument movement command signal. The method further provides for haptic feedback on a master control in response to restriction of the desired surgical instrument movement command signal.

A control method for removing scanning discontinuity in scanners. The relationship between a driving motor and an elastic body such as a leather belt or a steel cable linked to the chassis inside a scanner is investigated so that time constants for achieving system stability are found. Through setting the time constants, the forwarding and reversing motion of the chassis is controlled so that scanning discontinuity due to stopping and restarting is reduced.
