1. A hand-held, dual-mode barcode scanning device comprising:
- a) a hollow case sized and shaped to be held in a user'"'"'s hand;
b) a scanner disposed within said case in a position for scanning barcodes, said scanner having an output outputting a signal representing data contained in a scanned barcode;
c) a primary switch disposed within said case connected to said scanner, said switch being manually activatable by a user while gripping said case to initiate a scanning process;
d) a secondary switch disposed within said case manually activatable by a user while gripping said case and activating said primary switch; and
e) logic disposed within said case connected to said scanner, said primary switch, and said secondary switch for taking a first action when said primary switch is activated by a user but said secondary switch is not activated and for taking a second action when both said primary switch and said secondary switch are activated by a user, said first action comprising interpreting said signal in a first manner, and said second action comprising interpreting said signal in a second manner.

Abstract
A hand-held, dual-mode barcode scanner for two dimensional barcodes. A supplemental switch activatable by the user changes the function being performed by the scanner. In one implementation, the barcode data is used to reprogram the scanner'"'"'s logic when the supplemental switch is activated. The preferred embodiment employs a light-activated switch that is turned on by the user placing his/her finger/thumb over an opening in the scanner case. An infrared-activated version of the switch is also shown.

10. A light-activated switch comprising:
-
a) a hollow light-sealed case having an opening in a sidewall thereof; b) a photosensitive device having a light sensitive surface and an output producing an electrical signal at said output when light is striking said sensitive surface, said photosensitive device being disposed in said case with said sensitive surface being disposed to have light entering said opening strike it whereby said switch is "off" when said electrical signal is present on said output and said switch is "on" when said opening is blocked and said electrical signal is absent on said output; and c) a light-passing plastic dome disposed over said opening which oilcans when depressed to provide a tactile feel to a user as it moves to a collapsed position blocking light from entering said opening. - View Dependent Claims (11)

12. A hand-held, dual-mode, two dimensional barcode scanning device comprising:
-
a) a hollow case sized and shaped to be held in a user'"'"'s hand; b) a charge coupled device disposed within said case positioned to view two dimensional barcodes at a focal point thereof and having an output outputting a signal representing data contained in a two dimensional barcode being viewed; c) a primary switch disposed within said case connected to said charge coupled device, said switch being manually activatable by a user while gripping said case to initiate a process of scanning a two dimensional barcode; d) a secondary switch disposed within said case manually activatable by a user while gripping said case and activating said primary switch; and e) logic disposed within said case connected to said output of said charge coupled device, said primary switch, and said secondary switch for snapshotting said data on said output and taking a first action when said primary switch is activated by a user but said secondary switch is not activated and for taking a second action when both said primary switch and said secondary switch are activated by a user, said first action comprising interpreting said signal in a first manner, and said second action comprising interpreting said signal in a second manner. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

30. A hand-held, dual-mode, two dimensional barcode scanning device comprising:
-
a) a hollow case sized and shaped to be held in a user'"'"'s hand; b) scanning means disposed within said case and positioned for viewing two dimensional barcodes, said scanning means having an output for outputting a signal representing data contained in a two dimensional barcode being viewed; c) primary switching means disposed within said case for causing said scanning means to view a two dimensional barcode and output said signal; d) supplemental switching means disposed within said case for manual activation by a user while gripping said case; and e) logic disposed within said case connected to said output of said scanning means, said primary switching means, and said supplemental switching means for snapshotting said data on said output and taking a first action when said primary switching means is active but said supplemental switching means is not activated and for taking a superseding second action when said supplemental switching means is activated by a user and said primary switching means is active, said first action comprising interpreting said signal in a first manner, and said second action comprising interpreting said signal in a second manner. - View Dependent Claims (31, 32, 33, 34, 35, 36)
