System and methods for using a plurality of receiver identifications to create and retrieve a digital project log

1. In a system comprising a plurality of observers, each associated with one of a plurality of observer identifiers; a plurality of receivers none of which is associated with any particular project log or other destination, or to a particular observer, and each identified by a unique receiver identifier; and a table comprising at least one record for each observer authorized to submit observations, each record in such table comprising at least three data fields, the data fields including an observation identifier field, a receiver identifier field, and a project log identifier field, a method for updating a digital project log, comprising:

prior to accepting observations from an authorized observer regarding particular project, inserting a record in the data table, such record containing at least an observer identifier, a receiver identifier to which the observer will send observations for that particular project, and an identifier of the project log to which observations sent by that particular observer to the specified receiver will be associated;

receiving via one of the plurality of receivers an observation, the observation comprising an observer identifier associated with the observer sending the received observation;

selecting a project log by reference to the data table and based on the combination of the observer identifier included with the observation and the receiver identifier associated with the receiver used to receive the observation; and

storing information included in the observation in the selected project log.

2. The method of claim 1 , wherein the plurality of observer identifiers comprise cellular telephone numbers associated with cellular telephones used by the plurality of observers to send observations.

3. The method of claim 1 , wherein the plurality of receivers comprise a bank of cellular telephones, and wherein the plurality of receiver identifiers comprise cellular telephone numbers associated with the bank of cellular telephones.

4. The method of claim 1 , wherein the received observation comprises a voice signal.

5. The method of claim 4 , further comprising converting the voice signal to a digital audio signal.

6. The method of claim 1 , wherein the received observation comprises audio signals.

7. The method of claim 1 , wherein the received observation comprises video signals.

8. The method of claim 1 , wherein each of the observers uses a push-to-talk device to send observations, and wherein the plurality of observer identifiers identify the push-to-talk devices used by the plurality of observers.

9. The method of claim 8 , further comprising sending an observation by performing a transmit action.

10. The method of claim 9 , wherein the transmit action comprises pressing and holding a button on a push-to-talk device while the observer speaks the observation into the push-to-talk device.

11. The method of claim 10 , wherein the transmit action comprises pressing and releasing a button on a push-to-talk device before speaking the observation into the push-to-talk device, and pressing and releasing a button on the push-to-talk device when finished speaking.

12. The method of claim 1 , wherein storing the information includes converting the information into a digital file format.

13. A digital project log system, comprising:

a project log database comprising a plurality of project logs;

a plurality of receivers, none of which is associated with any particular project log or other destination, or to a particular observer, each of the plurality of receivers associated with a unique receiver identifier and configured to receive observations comprising observer identifiers related to the plurality of project logs, each observation comprising an observer identifier associated with a transmission device from which an observation was transmitted;

a data table comprising at least one record for each observer authorized to submit observations to the digital project log system, each record comprising at least three data fields, the data fields including an observation identifier field, a receiver identifier field, and a project log identifier field; and

a processor coupled with the plurality of receivers and the project log database, the processor configured to store a received observation in a project log by using the data table to select a project log identifier associated with the project log based on the observer identifier included in the received observation and the receiver identifier associated with the receiver used to receive the observation.

14. The digital project log system of claim 13 , wherein the plurality of receivers comprise a plurality of cellular telephones, and wherein the receiver identifiers are the cellular telephone numbers associated with each of the plurality of cellular telephones.

15. The digital project log system of claim 13 , wherein the plurality of receivers comprise a plurality of push-to-talk devices, and wherein the receiver identifiers are the push-to-talk numbers associated with each of the plurality of push-to-talk devices.

16. The digital project log system of claim 13 , wherein the observation are received from cellular telephones and wherein the observer identifiers are cellular telephone numbers associated with the cellular telephones.

17. The digital project log system of claim 13 , wherein the observation are received from push-to-talk and wherein the observer identifiers are push-to-talk numbers associated with the push-to-talk devices.

18. A digital project log system, comprising:

a project log database comprising a plurality of project logs;

a bank of push-to-talk devices, each push-to-talk device comprising an associated push-to-talk number and configured to receive voice signals comprising observations from a plurality of observer push-to-talk devices;

a data table comprising at least one record for each observer authorized to submit observations to the digital project log system, each record comprising at least three data fields, the data fields including an observation identifier field, a receiver identifier field, and a project log identifier field; and

a processor coupled with the bank of push-to-talk devices and the project log database, the processor configured to store an observation included in a received voice signal in a project log, the project log selected by reference to the data table and based on the push-to-talk number associated with the observer push-to-talk device from which the voice signal was received and the push-to-talk number associated with the push-to-talk device used to receive the voice message.
