Method and apparatus for pre-identification of keys and switches
First Claim
1. A system operable from at least one inputted signal, comprisingat least one switching means having first and second states, said first state being the default state while said second state being a partial requirement for producing a predetermined signal, said at least one switching means responsive to manual contact for changing its state from said first state to said second state for producing said predetermined signal regardless of the duration of the period of time in said second state after being in said second state continuously for at least a predetermined period of time,pre-identification means coupled to said at least one switching means and operable for producing a pre-identification signal when the state of said at least one switching means has been changed from said first state to said second state, said pre-identification signal identifying said predetermined signal to an operator,signal generating means operatively coupled to said at least one switching means for generating said predetermined signal after said at least one switching means has been maintained in said second state for said predetermined period of time, andtiming means operatively coupled to said at least one switching means for generating a timing signal for measuring a time period from when said at least one switching means is changed from its first state to its second state,whereby, said at least one switching means initially informs an operator as to the predetermined signal and thereafter, produces its predetermined signal if it is maintained in its second state throughout the predetermined time period as measured by said timing means regardless of any additional time said second state is maintained.

Abstract
A method and apparatus for keypads, for conveying audible, visual or tactile information to a user regarding the identity, function, proper usage or potential utility of a given key or group of keys. The information being invoked by the user through superficial or proximal manipulation of the given key without having pressed or manipulated it in a way that would invoke its normal function. The primary concern of the system is as an informational adjunct to a more traditional keypad.

1. A system operable from at least one inputted signal, comprising
at least one switching means having first and second states, said first state being the default state while said second state being a partial requirement for producing a predetermined signal, said at least one switching means responsive to manual contact for changing its state from said first state to said second state for producing said predetermined signal regardless of the duration of the period of time in said second state after being in said second state continuously for at least a predetermined period of time, pre-identification means coupled to said at least one switching means and operable for producing a pre-identification signal when the state of said at least one switching means has been changed from said first state to said second state, said pre-identification signal identifying said predetermined signal to an operator, signal generating means operatively coupled to said at least one switching means for generating said predetermined signal after said at least one switching means has been maintained in said second state for said predetermined period of time, and timing means operatively coupled to said at least one switching means for generating a timing signal for measuring a time period from when said at least one switching means is changed from its first state to its second state, whereby, said at least one switching means initially informs an operator as to the predetermined signal and thereafter, produces its predetermined signal if it is maintained in its second state throughout the predetermined time period as measured by said timing means regardless of any additional time said second state is maintained.

8. A system operable from at least one inputted signal, comprising
at least one switching means including first inputting means having first and second states and second inputting means having first and second states, the first state of said first inputting means being a default state, said first inputting means being responsive to manual contact for changing its state from said first state to said second state, the first state of said second inputting means being a default state and the second state of said second inputting means being operable for producing a predetermined signal, said second inputting means responsive to manual contact for changing its state from said first state to said second state, pre-identification means coupled to said at least one switching means and operable for producing a pre-identification signal when the state of said first inputting means has been changed from its first state to its second state, and signal generating means operatively coupled to said at least one switching means for generating said predetermined signal when said second inputting means is changed from its first state to its second state, said second inputting means being operable independent of said first inputting means so that said second inputting means can be used to generate said predetermined signal without a pre-identification signal being produced first, whereby an operator can first change the state of said first inputting means to its second state, learn from said pre-identification means the associated predetermined signal, and thereafter, change the state of said second inputting means from its first state to its second state to produce said predetermined signal or alternately, the operator can change the state of only the second inputting means to its second state to produce said predetermined signal.

15. A method of operating a system comprising at least one switching means having first and second states, said first state being the default state while said second state being a partial requirement for producing a predetermined signal, said at least one switching means responsive to manual contact for changing its state from said first state to said second state for producing said predetermined signal regardless of the duration of the period of time in said second state after being in said second state continuously for at least a predetermined period of time,
said method comprising changing said switching at least one means from its first state to its second state. generating a pre-identification signal when the state of said at least one switching means has been changed from said first state to said second state, said pre-identification signal identifying said predetermined signal to an operator, and generating said predetermined signal only after said at least one switching means has been maintained in its second state a predetermined period of time, whereby, a single change in the state of said at least one switching means initially enables the operator to identify the associated predetermined signal and maintaining the change in state for at least the predetermined period of time generates said predetermined signal.
