摘要:
An electromechanical switch is described, which comprises a conductive body and a plurality of carbon nanotubes being separate to each other, each of the carbon nanotubes being connected to at least one common terminal electrode with at least one of its ends, wherein in an open state of the switch each of the carbon nanotubes substantially projects along a surface of the conductive body and keeps up a gap to said surface, and wherein in a closed state of the switch at least one carbon nanotube is bend in a direction of the surface to close an electrical contact between said terminal electrode and the conductive body. The size of the gap between the respective carbon nanotube and the surface is different for each one of the plurality of carbon nanotubes.

The invention is related to non-volatile storage devices.The invention proposes a non-volatile storage device comprising a storage unit, means for receiving an access change indication and means for changing access to said storage unit in response to said access change indication wherein access prior to reception of said access change indication is such that data can be stored in said storage unit and already stored data can be altered and access after said access change is such that at least some of the already stored data is unalterable but still can be read wherein access to said at least some of the already stored data is irreversible after access change in response to receiving said access change indication.This combines the advantages of permanent, forgery-proof storage with the advantages of erasable storage.

Metadata transmitted in parallel to the broadcast information shall be made accessible independent of Internet availability. Therefore, it is proposed to download and store the data located on an Internet address pointed at by metadata link information. The storage is performed in parallel to the recording and is typically done onto the same media; i.e. DVR, hard disk, etc. By playing back the recorded data it is possible to access the complete data including all Internet pages pointed at.
摘要:
A bit cell of the PROM-device comprises a carbon nanotube having a tilted portion comprising a free end and a fixed portion which is to the reference node. The carbon nanotube comprises a structural defect between the fixed and the tilted portion which causes the carbon nanotube to tilt such that the free end is electrically connected to either the storage electrode or an opposite release electrode.
摘要:
A method and an apparatus for data storage based on fibers are described. Data are stored as marks in a surface of a fiber or in a volume near the surface of the fiber. Data marks are written to or read from the fiber by irradiating the surface of the fiber with at least one radiation beam. The fiber has calibration marks for controlling a speed of the fiber relative to the at least one radiation beam.
