Filed:

Nov 5, 1999

Appl. No.:

09/434698

Inventors:

Kenneth J. Pugh - Houston TX 77066

International Classification:

F41A 1706

US Classification:

42 7011, 42 7001, 42 7006, 42 66

Abstract:

This invention is a firearm automatic locking system and method using an emitter that produces an alternating electromagnetic field to induce an eddy current in an encoder presented by an authorized user of the firearm. A sensor in the firearm detects a unique signature of the eddy current, which unique signature is based on any combination of the size, weight, composition and shape of the encoder, which is typically a ring worn by the authorized user. The eddy current signature is then compared electronically to a pre-determined value. If the signature and value are equivalent, a power circuit is closed providing an electrical current to an electrical device, thereby mechanically enabling the firing mechanism of the firearm. As long as the encoder is in adequate proximity to the automatic locking system, the weapon can be fired. To conserve battery power, the automatic locking system is activated only when a magnetic reed switch is activated.

International Classification:

B29D 1100

US Classification:

264 25

Abstract:

Ophthalmic lens manufacturing equipment includes lens die assemblies constructed to accommodate fragile, high quality glass lens dies. The lens die supports of the assemblies provide a series of grooves of critically small widths on their interface surfaces to apply vacuum pressure from an external source to the backs of the lens dies and thereby hold them in place. The vacuum securement also enables rapid lens die changeover using robotic arms.

Appl. No.:

7/702230

Inventors:

Kenneth J. Pugh - Houston TX

International Classification:

F41A 1706
F41A 1746

US Classification:

42 7011

Abstract:

This invention teaches a safety device for preventing unauthorized firing of a weapon (H) of the type having a trigger (19) and mechanical firing mechanism (21) for firing the weapon. A solenoid (S) controllably actuates or deactuates upon the application of an electrical signal. A decoder (D) is mounted with the weapon for detecting a signal from an authorized user and selectively activating the solenoid upon the signal from the authorized user. Such decoder (D) is electrically connected to at least a power source (P) and to the solenoid (S). An encoder (E) creates the signal indicating that the possessor is authorized to use the weapon. A linkage (L) connects the solenoid (S) and the firing mechanism (F) for controllably enabling or disabling the weapon from being fired upon the desired activation of the solenoid.
