Abstract
A portable electronic device operable in a first mode and a second mode, comprising: input means having a first key and a second key, wherein, when the device is in the first mode, the device is not responsive to the individual actuation of the first key and, when the device is in the second mode, the device is responsive to the individual actuation of the first key; and disabling means, responsive when the device is in the first mode to the sequential actuation of the first key then the second key to at least partially disable the input means.
Claims25
A portable electronic device operable in a first mode and a second mode, comprising:
- input means having a first key and a second key, wherein, when the device is in the first mode, the device is not operable to perform a function associated with the first mode in response to the actuation of the first key when not followed by actuation of the second key and, when the device is in the second mode, the device is operable to perform a function associated with the second mode in response to the actuation of the first key when not followed by actuation of the second key;
- and disabling means operable to have a first state when the device is in the first mode and when the device is in the second mode and operable to have a second state when the device is in the first mode and when the device is in the second mode and responsive when the device is in the first mode and in the second state to the sequential actuation of the first key followed by actuation of the second key to enter the first state, wherein in the first state, the sequential actuation of the first key followed by the second key at least partially-disable the input means.
A portable electronic device operable in a first mode and a second mode, comprising:
- input means having a first key and a second key, wherein, when the device is in the first mode, the device is not operable to perform a function associated with the first mode in response to the actuation of the first key when not followed by actuation of the second key and, when the device is in the second mode, the device is operable to perform a function associated with the second mode in response to the individual actuation of the first key when not followed by actuation of the second key;
- and disabling means operable to have a first state when the device is in the first mode and when the device is in the second mode and operable to have a second state when the device is in the first mode and when the device is in the second mode, wherein the input means are at least partially disabled when the disabling means is in the second state than when the disabling means is in the first state, and, when the device is in the first mode and the disabling means is in a second state, the disabling means enters the first state following actuation of the first key and then the second key.
A method for locking and unlocking input means of a portable electronic device operable in a first mode in which the device is not operable to perform a function associated with the first mode in response to the actuation of a first key of the input means when not followed by the actuation of a second key of the input means and operable in a second mode in which the device is operable to perform a function associated with the second mode in response to the actuation of the first key when not followed by the actuation of the second key, comprising, when the device is in the first mode, actuating the first key and then a second key of the input means to further disable the input means through disabling means;
- and then actuating the first key and then the second key of the input means to remove the further disablement, wherein the disabling means is operable to have a first state when the device is in the first mode and when the device is in the second mode and operable to have a second state when the device is in the first mode and when the device is in the second mode, wherein the input means are at least partially disabled when the disabling means is in the second state.
A portable electronic device operable in a first mode in which the device is not operable to perform a function associated with the first mode in response to the actuation of a first key of the input means when not followed by the actuation of a second key of the input means and operable in a second mode in which the device is operable to perform a function associated with the second mode in response to the actuation of the first key when not followed by the actuation of the second key, comprising:
- input means having the first key and the second key, wherein the second key is a programmable key;
- a display for displaying a legend indicative of the function of the second key;
- and disabling means, responsive to actuation of the first key followed by actuation of the second key for at least partially disabling the input means including disabling the second key, wherein the disabling means has an activated state during which the input means are at least partially disabled and the disabling means enters the activated state in response to the actuation of the first key and then the second key, wherein the disabling means has a deactivated state during which the input means are not disabled and disabling means enters the deactivated state in response to actuation of the first key and then the second key.
A portable electronic device operable in a first mode and a second mode, comprising:
- an input device having a first key and a second key;
- and a processor operable, when the device is in a first mode, to perform a first function in response to input from the input device, and operable, when the device is in a second mode, to perform at least one other function in response to the actuation of the first key, but not operable to perform the first function, the at least one other function being different to the first function, wherein the processor is operable, when the device is in the first mode, to at least partially disable the first mode in response to the actuation of the first key followed by actuation of the second key, so that the processor is not operable to perform the first function in response to input from the input device, wherein the processor in disabling is operable to have a first state when the device is in the first mode and when the device is in the second mode and operable to have a second state when the device is in the first mode and when the device is in the second mode, wherein the input device is at least partialy disabled in the second state.
