US Patent:

50246267, Jun 18, 1991

Filed:

Feb 1, 1991

Appl. No.:

7/649407

Inventors:

Jack Robbins - Pompton Lakes NJ
Dietmar Nagel - Chester NJ

International Classification:

A63H 500
A63H 1734

US Classification:

446409

Abstract:

A remote control toy vehicle system includes a toy vehicle and a remote control. The toy vehicle includes a motor for selectively driving the toy vehicle. The remote control is electrically coupled to the toy vehicle and includes a manually actuatable first control switch for controlling the motor. The remote control also includes a sound producing circuit for selectively producing sounds related to the toy vehicle. Manually actuatable second control switches on the remote control the sounds producible by the sound producing circuitry.

Abstract:

A method and apparatus for identifying an article and detecting its unauthorized movement comprises disposing a predetermined amount of radioactive isotopes on or within the article. The plurality of radioactive isotopes has a characteristic gamma spectrum unique to that plurality. Continuous monitoring is used to obtain a signal to detect unauthorized movement of the article. For identification purposes, means is provided for resolving the unique gamma spectrum into isotopic abundances. The plurality of radioactive isotopes is disposed on the article in an amount which preferably does not exceed an activity level of about one microcurie. Additionally, the half-life of the plurality is matched to the period of time needed to protect a particular article. These parameters make the method and apparatus particularly suitable for identifying and detecting unauthorized movement of articles that previously were impractical to detect, as well as providing the mechanism for authenticating and dating articles in such a manner so as not to encumber or visibly display the presence of the deposited plurality on an article.
