Abstract

A method and apparatus for detecting and tracking an object within a defined area, and determining its position, status, movement and identity therein, includes interrogating the defined area to communicate with an information device associated with an object and transmit information received to a master controller unit, which determines the object'"'"'s presence, position, status, movement and identity within the defined area. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Claims

1-33. -33. (canceled)

34. An apparatus for tracking custody of evidence, comprising:

a first information device associated with an evidence collection vessel;

a first interrogation device for receiving identification information from a center and transmitting the identification information to the first information device;

an additional interrogation device capable of reading the identification information on the first information device when the evidence collection vessel is moved from a first location to at least one other location, the additional interrogation device positioned at the least one other location and certifying custody of the evidence collection vessel;

an additional information device associated with a piece of evidence in the evidence collection vessel; and

a master controller unit controlling transmission of the identification information to the additional information device when the piece of evidence is removed from the evidence collection vessel to maintain custody of the piece of evidence.

35. The apparatus of claim 34, wherein the master controller unit controls the first interrogation device to receive identification information from the center and to transmit the identification information to the first information device, and controls the additional information device to read identification information on the first information device when the evidence collection vessel moves from the first location to the at least one other location.

36. The apparatus of claim 34, wherein a plurality of information devices includes the first information device and the additional information device, each information device in the plurality of information devices being associated with a piece of evidence.

37. The apparatus of claim 36, wherein the evidence collection vessel comprises a plurality of pieces of evidence.

38. The apparatus of claim 34, wherein a plurality of information devices includes the first information device and the additional information device, each information device in the plurality of information devices being a radio frequency identification tag.

39. The apparatus of claim 36, wherein the identification information is tracked as the piece of evidence is moved between a plurality of different locations.

40-51. -51. (canceled)

52. A method of tracking information, comprising:

transferring identification information between a plurality of information devices, the identification information including a time of transfer, a location from transfer, a location to transfer, information describing a person handling a transfer, and descriptive information of circumstances of transfer, wherein at least one interrogation device interrogates an information device in the plurality of information devices, reads the identification information, and transfers the identification information to another information device in the plurality of information devices through at least one master controller unit.

53. The method of claim 52, further comprising comparing identification information stored on one information device within the plurality of information devices with identification information stored on another information device in the plurality of information devices to ensure accuracy of identification information between information devices.

54. The method of claim 53, wherein different information devices in the plurality of information devices are located at different locations, so that identification information is transferred from a first location to a second location.

55. The method of claim 54, further comprising comparing identification information at the first location with identification information at the second location to ensure accuracy of the identification information between different locations.
