Inventor: WILSON GLENN E
IPC: E05B19/20
Filed: 1989-12-05
Granted: 1994-11-22
Abstract: Invention:  IMPROVED LOCK COMBINATION DECODER Inventor:   GLENN E. WILSON Abstract of the Disclosure Apparatus for determining the opening combination of a safe lock includes a servo motor, a molded dial gripper that fits over the hub of the combination lock dial, and a high resolution rotary encoder, preferably one with a resolution of 1000 PPR.  The rotary encoder has a resolution of 0.09 degrees of rotation using quadrature, which permits the dial to be rotated accurately to within 1/10 of a digit.          A programmable logic and control circuit can rotate the dial for automatic implementation of a manipulation technique.          This permits the safe combination to be found in a rather short period of time, typically less than one hour.

Title: Digital optical switch
Inventor: VAN DER TOL JOHANNES J G M
IPC: G02F1/313
Filed: 1991-05-07
Granted: 1994-04-12
Abstract: In a digital optical switch which is based on the mode-selectivity principle, made up of a passive section (A) containing a first optical wave guide (1) and a second optical wave guide  (2)  and a switching section  (B) containing a third optical wave guide (3) and a fourth optical wave guide (4), both the required asymmetry and the bringing of the optical wave guides within or outside each other's interaction region are achieved with the aid of curves (K1, K2) in said optical wave guides. In the switching section (B) said asymmetry is switchable. Use is made of the effect that a curve results, in general, in a reduction of the propagation constant in the optical wave guide. Suitable curves are of circular-arc shape and sinusoidal. The switching section (B) may furthermore incorporate a short intermediate section (s-u) in which the optical wave guides (12, 13) run straight at a small mutual angle (.PHI.) in the event that the switchable asym-metry is in the first instance too small with a par-ticular choice of material. The invention makes possible much shorter  switches which have a greater packing density.
