摘要:
A method of managing a distributed storage system (1) comprising a plurality of storage devices (D1, D2, . . . , Dn) on a network (N), wherein an autonomous function can be assigned to any storage device (D1, D2, . . . , Dn) of the distributed storage system (N), which autonomous function comprises collecting content according to a configurable profile (3) for the storage device (D1, D2, . . . , Dn) to which the autonomous function is assigned, and wherein a first storage device (D1, D2, . . . , Dn) of the distributed storage system (1), before leaving the network (N), delegates the responsibility for an autonomous function of that first storage device (D1, D2, . . . , Dn) to a second storage device (D1, D2, . . . , Dn) of the distributed storage system (1), and wherein the second storage device assumes responsibility for the autonomous function of the first storage device (D1, D2, . . . , Dn), and wherein the second storage device transfers data, accumulated due to its responsibility for the autonomous function of the first storage device (D1, D2, . . . Dn), to the first storage device (D1, D2, . . . , Dn) when the first storage device (D1, D2, . . . , Dn) returns to the network (N). The invention also relates to a storage device (D1, D2, . . . , Dn) for use in a distributed storage system (1), and to a distributed storage system (1) comprising such storage devices (D1, D2, . . . , Dn).
摘要:
A portable data storage device (1) is disclosed to be used for organizing content (10, 11, 18) available to the data storage device (1). The device comprises means (12) for setting an information source (6) for a storage profile (9), a means (3) for receiving storage profile update data (7) from the information source (6), a means (4) for updating the storage profile (9) based upon the storage profile update data (7), a means (2) for organizing content (10, 11) based upon the storage profile (9) and a means (12, 13) for triggering the means (3) for receiving storage profile update data (7) from the information source (6). The device (1) is capable of organizing content in a dynamic manner based on data storage profiles that are also dynamic in nature whilst requiring minimum user intervention.

摘要:
A data storage system comprises a plurality of portable data storage devices (12) coupled via a network (10). Each of the portable data storage devices (12) has an associated storage profile, which defines a which data objects will be stored in the storage device. A recommended profile for at least one of the portable data storage devices us automatically generated, using the steps of—collecting profile information about storage profiles for portable data storage devices (12) other than the at least one of the portable data storage devices (12) and/or data object information about properties of data objects stored by the portable data storage devices (12) other than the at least one of the portable data storage devices (12), —using the profile information and/or data information to guide generation of the recommended storage profile.

摘要:
A system (11, 50) and method is disclosed to be used for physically locating content (12) in a network (10). Further, a device is disclosed for use in the system and a computer program product enabling the disclosed method. The system comprises an input means (53) allowing a user to identify content (12) which is to be physically located, for example, via a computer or television user interface. A device (11) storing the content (12) is identified physically within the network. The device provides a signal (45) which the user is physically susceptible to, for example, a visual indication. The user is therefore assisted in the physical location of content that has been virtualised in the network. Such a system is especially useful when the device comprised within the network is a portable storage device that the user would like to quickly locate and take away.
摘要:
A system for determining the position of an object (8) in a space (10) defined by surfaces (11, 12) comprises at least a first transducer (1), a second transducer (2) and a processing device. The transducers are arranged at a mutual spacing (D). The processing device is arranged for determining the times of arrival of both acoustic signals transmitted between the object and each of the transducers (1, 2) and their reflections. On the basis of the difference in the times of arrival of clusters of acoustic signals and the associated reflections the processing device can determine which surface (11, 12) the indirect acoustic signals were reflected by, thus providing additional position information.
摘要:
A location system including a base station (120, 200) and a responder tag (140, 250) that communicate using an acoustic signal to determine the location of the tag in a bounded 3D space (100). The base station transmits a request signal (310) encoded with the identifier of a particular tag. The particular tag responds after a fixed delay (t2−t1) with an acoustic response signal (330). The base station determines the location of the tag based on the received line of sight signal (330) and its reflections (340). The response signal may be encoded with data indicating a status of the tag, or data from associated sensors (270) or actuators (280). The request signal may also be encoded with data for controlling the tag or the associated sensors and actuators. A power management scheme may be carried out by the tag.
