Abstract

A remote hand-held data collection device associates time with charge accounts at the instant when and the place where work is performed. The device obtains a set of descriptive codes that describe a work assignment and accrues time during which the work assignment is performed. A new work assignment may be quickly described by updating only those descriptive codes that differ from the previously entered set. The device is capable of checking the validity of the descriptive codes by comparing them to a number of valid input codes stored in a memory. The work-related records are stored in a database that is eventually uploaded to a central compiling computer for formatting and processing. An edit feature allows the user to modify erroneous data in the database, and a comment feature allows the user to enter alphanumeric messages into the database.

Claims

1. A method of operating a remote hand-held data collection device to associate time with accounts at the instant when and the place where work is performed, said method comprising the steps of:

obtaining, through a user interface portion of said hand-held data collection device, N descriptive codes that identify a first work assignment, wherein N is an integer greater than one;

initiating, in a time monitor portion of said hand-held data collection device, accrual of time for a first time period during which said first work assignment is performed, said initiating step being performed in response to said obtaining step;

acquiring, through said user interface, M updated descriptive codes that identify a second work assignment, wherein M is an integer greater than zero and less than N; and

beginning, in said time monitor, accrual of time for a second time period during which said second work assignment is performed, said beginning step being performed in response to said acquiring step.

2. A method according to claim 1, further comprising the step of recording a date stamp in a memory portion of said hand-held data collection device, said date stamp corresponding to said first and second time periods.

3. A method according to claim 1, further comprising the steps of:

switching to a comment mode in response to a user input at said user interface; and

writing a user-entered message received at said user interface into a database located in a memory portion of said data collection device, said writing step occurring after said switching step.

4. A method according to claim 3, further comprising the step of activating a warning flag associated with said message in said memory, said activating step being performed in response to said switching step.

5. A method according to claim 1, further comprising the step of comparing, in a processor portion of said hand-held data collection device, one of said N descriptive codes to one or more valid input codes stored in a memory portion of said data collection device, wherein said initiating step is performed when said one descriptive code matches one of said valid input codes.

6. A method according to claim 1, wherein said N descriptive codes and said M updated descriptive codes are stored in a database located in a memory portion of said data collection device, and wherein said method further comprises the steps of:

receiving an access code, through said user interface of said data collection device;

comparing, in a processor portion of said hand-held data collection device, said access code to a security code stored in said memory portion of said data collection device; and

permitting writable access to said database when said access code matches said security code.

7. A method according to claim 6, wherein said database located in said memory includes time duration data associated with the time accrued during each of said first and second time periods, and said method further comprises the step of preventing writable access to said time duration data.

8. A method according to claim 6, further comprising the step of editing one of said N descriptive codes and M updated descriptive codes, said editing step occurring after said permitting step.

9. A method according to claim 8, further comprising the step of terminating writable access to said database, said terminating step being performed after said editing step.

10. A method according to claim 8, further comprising the step of activating a warning flag associated with said one descriptive code stored in said database located in said memory to indicate status of said one descriptive code.

11. A method of operating a remote hand-held data collection device to associate time with accounts at the instant when and the place where work is performed, said method comprising the steps of:

obtaining, through a user interface portion of said hand-held data collection device, a plurality of descriptive codes that identify a work assignment;

comparing, in a processor portion of said hand-held data collection device, one of said obtained descriptive codes to one or more valid input codes stored in a memory portion of said data collection device; and

initiating, in a time monitor portion of said hand-held data collection device, accrual of time for a time period during which said work assignment is performed, said initiating step being performed in response to said comparing step.

12. A method according to claim 11, wherein said initiating step is performed when said one descriptive code matches one of said valid input codes.

13. A method according to claim 11, further comprising the steps of:

receiving, through said user interface, an access code when said one descriptive code differs from each of said valid input codes; and

comparing, in said processor, said access code to a security code stored in said memory of said data collection device;

wherein

said initiating step is performed when said access code matches said security code.

14. A method according to claim 13 wherein said one descriptive code is stored in said memory and said method further comprises the step of activating a warning flag associated in said memory with said one descriptive code to indicate status of said one descriptive code, said activating step occurring when said access code matches said security code.

15. A method according to claim 11, wherein N represents the number of said descriptive codes from said obtaining step, said descriptive codes are stored in said memory, and wherein said method further comprises the steps of:

acquiring, through said user interface, M updated descriptive codes such that a second work assignment is described, wherein M is an integer greater than zero and less than N; and

beginning, in said time monitor, accrual of time for a second time period during which said second work assignment is performed, said beginning step being performed in response to said acquiring step.

16. A method according to claim 11, wherein said obtained descriptive codes are stored in a database located in a memory portion of said data collection device, and wherein said method further comprises the steps of:

receiving an access code through said user interface of said data collection device;

comparing said access code to a security code stored in said memory portion of said data collection device; and

permitting editing of said descriptive codes when said access code matches said security code.

17. A method according to claim 11, further comprising the step of recording a date stamp corresponding to said time period in said memory.

18. A method of operating a remote hand-held data collection device to associate time with accounts at the instant when and the place where work is performed, said method comprising the steps of:

obtaining, through a user interface portion of said hand-held data collection device, a plurality of descriptive codes that identify a work assignment;

storing said descriptive codes in a memory portion of said hand-held data collection device so that each of said descriptive codes has a warning flag indicator associated therewith;

initiating, in a time monitor portion of said hand-held data collection device, accrual of time for a time period during which said work assignment is performed, said initiating step occurring in response to said obtaining step; and

selectively activating said warning flag indicators in response to a user input received through said user interface.

19. A method according to claim 18, wherein:
