Filed:

Nov 9, 1993

Appl. No.:

8/149388

Inventors:

Edward H. Kerman - Rockville MD

International Classification:

B65D 9006

US Classification:

220453

Abstract:

A containment device is formed by an outer container having a curtain-covered front opening and separate removable and replaceable protective panels mounted within the container adjacent to each of the walls thereof. Each protective panel is formed of a composite of layers, including an outer energy absorbing layer closest to the container walls, an intermediate ballistic shield layer, and an inner elastomeric layer. A firearm to be inspected, loaded or unloaded is positioned with its muzzle pointing toward the curtain at the front opening of the device whereby, if the firearm accidentally discharges, the projectile will pass through the curtain, the inner elastomeric layer, and become entrapped and contained within or adjacent to the ballistic shield layer. The outer energy absorbing layer prevents damage to the wall of the container. If one of the protective panels becomes damaged or deformed, it can be individually replaced.

Abstract:

An interactive compact disc system (10) having a teaching mode in addition to an entertainment mode is provided for the recovery of a predetermined aural response from predetermined randomly accessed storage on a compact digital disc. The interactive compact disc system (10) includes a mode select switch interface (26) which is coupled to microprocessor (22) by data bus (34) and address bus (32) for selecting the desired operational node. A keyboard (12) which includes a removable graphic overlay, provided for use in the teaching mode, is coupled to keyboard decoder/driver (14). Keyboard decoder/driver (14) generates a unique character code for each of the keyboard switches in keyboard (12). Microprocessor (22) uses that unique character code to generate an address for accessing the track encoder read only memory (24). Track encoder read only memory (24) provides a lock-up table which in effect cross references each keyboard key switch with a discrete audio segment on a compact digital disc located in disc playback unit (30).
