Title: Controlling a driven member, eg a robot arm, when a collision is detected
Inventor: SANO MASATOSHI
IPC: B25J19/06
Filed: 2000-10-20
Abstract: Collision of a driven member, eg the end effector of a robot arm, with an unexpected obstacle is detected by determining the deviation Ad(i) of the actual current in each servomotor of the arm from the logical current A(i), ie that which should be flowing through the servomotor according to its controlled operation. If this deviation Ad(i) or the differential dAd(i)/dt of this deviation exceeds a predetermined reference value AS(i) or (ADS(i), then a collision is judged to have occurred. The servomotors are then controlled, in a "Stress Removal Process" to return the end effector for a predetermined distance along the path it had been following before the collision, the path being stored in memory. In a further detail, for each servomotor, the sign (+/-) of the logical current value A(i) minus the actual current value at the time of impact is compared with the sign of the logical current value A(i). If they are of the same sign, the servomotor is driven after the collision in the same direction as before the collision, if they are different, then the servomotor is reversed.

IPC: B60R25/042
Filed: 2001-10-27
Abstract: The vehicle anti-theft device uses a radio receiver and decoder, as part of the circuit. Each module has its own PIN, and using a standard telephone, operates the unit. The number supplied, followed by the PIN and Code, is entered in the telephone to activate the unit. Once the module receives the signal, data is fed through a diode D1 and R1, used to protect the module from any feedback. This data will then switch on TR1, passing a current to RL1, and close the contacts RL1A, and feed the LED via R2. The LED will now illuminate to show that device is activated, and that a heavy relay RL2 has been switched on. The contacts of RL2A will now be closed, and the vehicle fuel pump cut off. (See Figure 1). Activation takes approximately 30 seconds, deactivation uses the same procedure, with a different code.
