Abstract: Systems and methods of performing image data retention associated with a computer vision system are described. In one exemplary embodiment, a method is performed by a network node operationally coupled to a set of optical sensor devices positioned about a retail space. Further, each optical sensor device has a field of view towards a certain region about the retail space and is operable to capture sequential images that correspond to the certain region. The method includes storing, in non-volatile memory, data that corresponds to the sequential images captured the optical sensor devices of a subject as that subject traverses about the retail space. The method also includes selecting a portion of the stored image data that corresponds to a physical view of the subject or a certain activity performed by the subject while about the retail space to retain in the non-volatile memory.

Abstract: A system and method for transmitting an electronic mail message to one or more intended recipients, which allows the user to designate that an electronic mail message contains a request for information which requires a reply from the one or more intended recipients, monitors electronic mail messages incoming to the sender to detect whether a reply has been received within the response period, and upon receiving a reply from any of the one or more intended recipients, presents the reply to the sender with one or more user-selectable icons which allow the sender to accept the reply as sufficient or request more information from the one or more intended recipients in response to selection of a user-selectable icon.
