Abstract
Abstract A system is disclosed for facilitating later access to a portion of a datastream for retrieval purposes based upon identifying "episodes" in data from other sources related to a user's activities. The stored data, in raw or "episodic " form, are accessed as desired using parameters based on recollections of the user's or database interrogator's activities at the time of the event which the user or interrogator wishes to access or display. Such other sources may include information about the movements, gatherings, conversations, phone calls, etc. of users in a particular environment fitted with the system.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
131 words
A system for providing for fast random access to a sequence of time-stamped data records of events in a specific environment, comprising: means for collecting data in order to construct time-stamped records indicating the locations of persons in the environment; means for encoding and storing the records for later selective retrieval and decoding; means for specifying a pattern characterising an episode as defined, and for receiving and decoding matching records; means for applying rules to the records to arrive at records of episodes matching a specified search pattern, in which each episode record is made up of periods spent alone by the person concerned; in travel within the environment, and in attendance at gatherings, and means for requesting transformation into human-readable form of the episode records corresponding to the specified pattern.
Claim 2
Dependent Claim
40 words
A system as claimed in claim 1, in which the environment is divided into several zones, and including: means for monitoring one or more of the zones to detect the presence within the zone of, and to identify, a person.
Claim 3
Dependent Claim
38 words
A system as claimed in claim 1 or 2, in which at least some of the people in the environment carry a personal identifier from which data can be collected by one or more monitors of the environment.
Claim 4
Dependent Claim
27 words
A system as claimed in claim 3, in which each identifier is in the form of a transmitter of identification signals to which each monitor is sensitive.
Claim 5
Independent Claim
71 words
A system for providing for fast random access to a sequence of time-stamped data records of events in a specific environment, comprising: means for collecting data in order to construct time-stamped records identifying scannable document pages and indicating operations on the pages at locations in the environment; means for encoding and storing the records for later selective retrieval and decoding; means for enabling identification of the document contents from a record.
Claim 6
Dependent Claim
28 words
A system as claimed in claim 5, including means for projecting a display on to the surface of the document or on to a surface bordering the document.
Claim 7
Dependent Claim
30 words
A system as claimed in claim 5 or 6, including means for manually selecting from within this document or for displaying a computer function to be applied to the document.
Claim 8
Independent Claim
39 words
A system as claimed in any of claims 5 to 7, including means for manually selecting one or more items on the identified document to be used as input to a computer function to be applied to the document.
Claim 9
Independent Claim
98 words
A system for providing for fast random access to asequence of time-stamped data records of activities in a specific environment , comprising: means for collecting data in order to construct time-stamped records of periods of vocal sounds by people in the environment; means for operating on those records to determine when a conversation is taking place involving one or more of the said people, and for generating time-stamped records of such determinations; means for encoding and storing the records for later selective retrieval and decoding, and means for enabling identification of the collected conversation data from a record.
Claim 10
Independent Claim
114 words
A system for providing for fast random access to a sequence of time-stamped data records of activities in a specific environment, comprising: means for collecting audio signal and other data from a person in the environment placing or receiving a phone call in order to construct time-stamped records of calls; means for feeding audio signals from these records to a speech recogniser capable of identifying the other participant in the call from the words uttered by the person in the environment, and for adding this identification to the records; means for encoding and storing the records for later selective retrieval and decoding, and means for enabling identification of the call data from a record.
Claim 11
Independent Claim
96 words
A system for providing for fast random access to a sequence of time-stamped data records of activities in a specific environment, comprising: means for collecting data in order to construct time-stamped records of the activity of each workstation associated with each person in the environment, such as the creation, reading, modification or deletion of electronic files; means for encoding and storing the records for later selective retrieval and decoding; means for specifying a pattern characterising an episode, and for receiving and decoding matching records, and means for enabling identification of the collected data from a record.
Claim 12
Independent Claim
63 words
A system as claimed in claims 4 and 9, in which each transmitter has associated with it a microphone for monitoring the level of the audio signals produced by the person carrying the transmitter, the microphone circuit having a filter for rejecting all signals of less than a threshold level, and transmitting data describing periods of vocal sounds greater than the threshold level.
Claim 13
Independent Claim
25 words
A system as claimed in any preceding claim, comprising means for producing at least auditory records of what was said in each of the zones.
Claim 14
Independent Claim
35 words
A system as claimed in any preceding claim, capable of generating episodes of two or more types, including means for arriving at episode records satisfying a specified relationship between episodes of two or more types.
Claim 15
Independent Claim
61 words
A system as claimed in any preceding claim, including: means for specifying a pattern characterising an episode as defined, and for receiving and decoding matching records; means for applying rules to the records to arrive at records of episodes matching a specified search pattern, and means for requesting transformation into human-readable form of the episode records corresponding to the specified pattern.
