Patent CA-2220176-A1 (CA)
Inventor: DE LIMA CASTRO NETTO EDUARDO
IPC: G09F3/03
Filed: 1996-05-03
Abstract: A padlock type marking seal having a receiving body (2) with internal locking teeth (4) to receive the tip (9) of a loop of the seal that is integral with the body, and there being a marking tab (6) also integral with the body (1). In order to improve seal application, to ensure autopenetration into the material to be marked (e.g. meat), the tip is sharpened and there is a stop (11) on the loop, adjacent to and behind the tip so as to allow an applicator device to force the sharpened point to penetrate the material to be marked. The loop of the seal has a reduced thickness region defining a pivot point (8) with respect to the body, and the part (7) of the loop between the first end and the sharpened tip is substantially in the form of the arc of a circle. A reception cavity (3) in the body of the seal has an axis substantially tangential to the arc when the loop is pivoted about the pivot point, until its tip begins to enter said cavity. The applicator according to the invention is in the form of a pistol and is adapted to receive comb of seals. The applicator is operated pneumatically to: apply seals without the applicator element (39) having to penetrate the material to be marked; feed the next seal to the reception and application station (25); and cut the links (12) with the following seal before its application. The pistol is fired by a trigger and the operating sequence is controlled and effected by a remote control unit (15) comprising electronic control circuits (44) and pneumatic valves (l6).

Title: Slaved reference control loop
Inventor: CLARK JOHN J
IPC: F41G7/22
Filed: 1998-06-11
Abstract: A gimbled camera (34) is attached to a moving body (20)  so that it can remain pointed at a desired target (28) as the body (20) moves.  A gyroscope (38) is attached to the camera (34) so that it may move independently from the camera (34), so that the gyroscope (38) continuously points  in one  direction while  the  camera  (34)  moves relative  to  the  gyroscope  (38).   Measurement  devices determine  the  positions  of  the  moving body  (20)  and gyroscope (38) relative to the camera (34).   The sum of these measures yields the position of the target relative to the gyroscope (38), which translates to a command to point the gyroscope (38) at the target.  The camera (34) is  then moved independently to  a  specified alignment relative to the gyroscope (38).
