Embodiments of the invention provide a file system that can store files or data streams in such a manner as to increase the effective storage capacity of the device on which the files or data stream are stored. In one embodiment, a system for processing and storing data comprises a first processing module configured to receive data directed to the system, the data comprising a first portion and a second portion; a second processing module configured to store the first portion of the data within a data storage device and remove the second portion of the data; a third processing module configured to retrieve the first portion of the data from the data storage device, the first portion of the data being combined with filler data to form reconstituted data; and a fourth processing module configured to send the reconstituted data to an output device.

A wireless encryption key integrated storage system is provided to prevent unauthorized access of data stored on the storage device without secure authentication between the storage device and a key device. In one embodiment, a data storage device comprises a magnetic disk; a head assembly having a read/write head which read and write data from/on the magnetic disk; a wireless transceiver configured to receive and transmit wireless signals from a key device, the wireless signals comprising information used to establish a secure authorization between the data storage device and the key device to access secured content in the magnetic disk; and a processor configured to encrypt/decrypt data transferred between the data storage device and the key device.

A data storage device can be validated through a network before the data storage device can be operated. In one embodiment, the data storage device includes a magnetic disk and a head assembly having a read/write head which reads and writes data from/on the magnetic disk. The data storage device further includes a controller configured to control the head assembly to read/write data to/from the magnetic disk. In addition, the data storage device includes a secure area of the magnetic disk containing a private key. The private key is one of a pair of cryptographically linked keys and the other of the cryptographically linked keys is a public key. Furthermore, the data storage device includes a memory located within the controller containing an auxiliary key, the auxiliary key being used to encrypt or decrypt the private key.

Time-of-flight (TOF) three-dimensional sensing systems are deployed on or in a motor vehicle to image contact zones associated with potential contact between an avoidable object and the vehicle or vehicle frame and/or remotely controllable motorized moving door or liftgate. An algorithm processes depth data acquired by each TOF system to determine whether an avoidable object is in the associated contact zone. If present, a control signal issues to halt or reverse the mechanism moving the door. A stored database preferably includes a depth image of the contact zone absent any object, an image of the door, and volume of the door. Database images are compared to newly acquired depth images to identify pixel sensors whose depth values are statistically unlikely to represent background or the door. Pixels within the contact zone so identified are an object, and the control signal is issued.

Embodiments of the present invention provide a data storage apparatus with new features to more easily enable atomic transactions. Rather than having the host system issue the multiple logging commands to the data storage apparatus, the data storage apparatus can be modified so that it can perform the logging function itself. In one embodiment, a data storage controller of a data storage apparatus for implementing an atomic transaction comprises a receiving module configured to receive from a host one or more commands to be executed as an atomic transaction; a log recording module, configured to record in a nonvolatile storage a log containing the one or more commands of the atomic transaction, the log to be administered by the data storage controller and not by the host; and an execution module configured to perform the one or more commands of the atomic transaction.

摘要:
An apparatus effectively filters infrared light from fluorescent lighting using a cover that is easily adapted to typical fluorescent lighting and assemblies. A cover for a fluorescent light bulb or lighting fixture operates to filter infrared light. The cover includes infrared filtration or blocking properties for substantially preventing emission of infrared light from the fluorescent light or lighting fixture. Transmission reduction may also be provided.
摘要:
Embodiments of the present invention provide a method and a system for monitoring a storage device for usage and warranty. In one embodiment, a data storage apparatus comprises a nonvolatile storage; and a data storage controller configured to store a log of status parameters of the data storage apparatus in the nonvolatile storage. The log of status parameters of the data storage apparatus in the nonvolatile storage is not resettable. Storing of the log of status parameters of the data storage apparatus in the nonvolatile storage cannot be disabled.
