Abstract
Abstract A portable terminal includes a housing and a sensor for sensing different specific positional orientations of the housing. In one positional orientation sensed by the sensor, the terminal performs a first function. In another positional orientation sensed by the sensor, the terminal performs a second function which is different from the first function.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
55 words
A portable terminal, comprising: a housing; and a sensor for sensing different specific positional orientations of the housing; wherein in one said positional orientation sensed by said sensor the terminal performs a first function, and in another said positional orientation sensed by said sensor the terminal performs a second function different from said first function.
Claim 2
Dependent Claim
55 words
A portable terminal, comprising: a housing; and a sensor for sensing different specific positional orientations of the housing; wherein in one said positional orientation sensed by said sensor the terminal performs a first function, and in another said positional orientation sensed by said sensor the terminal performs a second function different from said first function.
Claim 3
Dependent Claim
79 words
A portable terminal according to claim 1, further comprising (i) a touch sensitive display disposed on a surface of said housing and (ii) a light emitter for emitting a light beam through a window in said housing toward indicia having parts of different light reflectivity; wherein said first function is interpreting touches of the touch sensitive display as data input, and said second function is responding to a touch of the touch sensitive display by activating the light emitter.
Claim 4
Dependent Claim
54 words
A portable terminal according to claim 2, further comprising an optical detector for receiving reflected light from said indicia through the window in said housing and producing an electrical signal representative of said indicia; wherein said second function further includes responding to said touch of the touch sensitive display by activating the optical detector.
Claim 5
Dependent Claim
55 words
A portable terminal according to claim 3, further comprising a processor for receiving said data input and a signal corresponding to said electric signal, wherein said processor deactivates said touch sensitive display, said light emitter and said optical detector if neither said data input nor said signal is received within a predetermined period of time.
Claim 6
Independent Claim
52 words
A method of operating a portable terminal comprising the steps of: sensing different specific positional orientations of the portable terminal; performing a first function with said portable terminal in one said positional orientation; and performing a second function different from said first function with said portable terminal in another said positional orientation.
Claim 7
Independent Claim
52 words
A method of operating a portable terminal comprising the steps of: sensing different specific positional orientations of the portable terminal; performing a first function with said portable terminal in one said positional orientation; and performing a second function different from said first function with said portable terminal in another said positional orientation.
Claim 8
Dependent Claim
55 words
A method according to claim 5, further comprising the steps of: touching a portion of said portable terminal with said portable terminal is in said one positional orientation to perform said first function; and touching said portion of said portable terminal with said portable terminal in said another positional orientation to perform said second function.
Claim 9
Dependent Claim
32 words
A method according to claim 5, wherein said first function includes emitting a light beam from said portable terminal toward indicia separated from said terminal and having parts of different light reflectivity.
Claim 10
Dependent Claim
27 words
A method according to claim 7, wherein said first function further includes receiving reflected light from said indicia and producing an electrical signal representative of said indicia.
Claim 11
Dependent Claim
17 words
A method according to claim 7, wherein said second function includes inputting operator data to said terminal.
Claim 12
Dependent Claim
21 words
A method according to claim 5, further comprising the step of deactivating said portable terminal in a third said positional orientation.
Claim 13
Dependent Claim
41 words
A portable terminal according to claim 5, further comprising the step of deactivating said terminal if neither an operator input to said terminal nor a signal representing reflected light detected by said terminal is received within a predetermined period of time.
