Modular system for inventory control

Claim 1

A modular and portable system for inventory control, comprising: a hand-holdable scanning module comprising: (i) a head portion including: a scanner for projecting light at an object, detecting light reflected from the object, and generating an electrical signal representative of the object, programmable decode electronics coupled to said scanner for receiving the electrical signal and decoding it to interpret the object, and a first interconnector coupled to said programmable decode electronics; and a handle portion formed integrally with said head portion and including: activating means for causing said scanner to generate the electrical signal, and a battery for supplying power to said scanner and said programmable decode electronics in said head portion; and (b) a programmable master module releasably coupled to said scanning module to form a potable scanner device capable of reading and analyzing objects and storing information related thereto, said master module comprising: (i) a display, (ii) a keypad, (iii) memory, (iv) programmable processing electronics coupled to the display, keypad, and memory, and (v) a second interconnector, coupled to the processing electronics, for interconnecting with said first interconnector of said scanning module to form said portable scanner device, wherein said master module also is releasably couplable with any one of a plurality of non-scanning modules when released from said scanning module.

Claim 8

A method of performing inventor control functions, comprising: providing a modular and portable system comprising: (A) a light-weight, hand-holdable scanning module comprising: (i) a head portion including: a scanner for projecting light at a bar code symbol, detecting light reflected from the symbol, and generating an electrical signal representative of the symbol, programmable decode electronics coupled to said scanner for receiving the electrical signal and decoding it to interpret the symbol, and a first interconnector coupled to said programmable decode electronics; and (ii) a handle portion formed integrally with said head portion and including: activating means for causing said scanner to generate the electrical signal, and a battery for supplying power to said scanner and said programmable decode electronics in said head portion; and (B) a light-weight, programmable master module releasably coupled to said scanning module to form a portable and programmable scanner device, said master module comprising: (i) a display, (ii) a keypad, (iii) memory, (iv) programmable processing electronics coupled to the display, keypad, and memory, and (v) a second interconnector, coupled to the processing electronics, for interconnecting with said first interconnector of said scanning module to form said portable and programmable scanner device, wherein said master module also is releasably couplable with any one of a plurality of non-scanning modules when released from said scanning module; decoupling said scanning module from said master module and using said scanning module to read and decode bar code symbols; and coupling said scanning module to said master module to form said portable and programmable scanner device and using said device to read and analyze bar code symbols and to store information related thereto.

Claim 9

A method of performing inventor control functions, comprising: providing a modular and portable system comprising: (A) a light-weight, hand-holdable scanning module comprising: (i) a head portion including: a scanner for projecting light at a bar code symbol, detecting light reflected from the symbol, and generating an electrical signal representative of the symbol, programmable decode electronics coupled to said scanner for receiving the electrical signal and decoding it to interpret the symbol, and a first interconnector coupled to said programmable decode electronics; and (ii) a handle portion formed integrally with said head portion and including: activating means for causing said scanner to generate the electrical signal, and a battery for supplying power to said scanner and said programmable decode electronics in said head portion; and (B) a light-weight, programmable master module releasably coupled to said scanning module to form a portable and programmable scanner device, said master module comprising: (i) a display, (ii) a keypad, (iii) memory, (iv) programmable processing electronics coupled to the display, keypad, and memory, and (v) a second interconnector, coupled to the processing electronics, for interconnecting with said first interconnector of said scanning module to form said portable and programmable scanner device, wherein said master module also is releasably couplable with any one of a plurality of non-scanning modules when released from said scanning module; decoupling said scanning module from said master module and using said scanning module to read and decode bar code symbols; and coupling said scanning module to said master module to form said portable and programmable scanner device and using said device to read and analyze bar code symbols and to store information related thereto.
