摘要:
Storage devices can provide for hardware encryption and decryption of data stored by them. The hardware cryptographic functions can be applied with reference to cryptographic information of a communicationally, and physically, separable key device. Disconnection of the separable key device can render encrypted data inaccessible. Destruction of the separable key device can result in virtual destruction of the encrypted data. The cryptographic information on the separable key device can be provided by a storage device manufacturer, or by a provisioning computing device. The separable key device can be directly communicationally coupled to a provisioning computing device or it can establish a secure communication tunnel with the provisioning device through a computing device to which the separable key device is communicationally coupled. Cryptographic information can be provided by, and deleted from, the provisioning computing device prior to completion of the booting of that device.

Automatic protocol migration when upgrading operating systems includes checking, after upgrading at least a portion of an operating system of a host device, whether a new driver supporting enhanced functionality for a portable device is now available, where a driver supporting base functionality would have been previously used for communicating with the portable device. If such a new driver supporting enhanced functionality for the portable device is now available, then the host device installs the new driver supporting enhanced functionality for the portable device.

A system and method for image acquisition enables selective automated application of color management to color image data generated by an image-capturing device by the device driver for the device. In the image acquisition system, each image-capturing device has properties or operation parameters that can be set to control the operation of the device. During an image acquisition operation, color image data generated by the image-capturing device are transmitted to the device driver. If the operation parameters of the device are set to indicate that color management is to be performed, the device driver calls color management functions provided by the operating system to perform the desired color operation, such as a color space conversion, on the received color image data. The processed color image data are then sent to the image-processing application for further processing or editing.

Providing for improved transactioning for Flash memory is described herein. By way of example, transactioning operations associated with abstract data structures can be bundled into a common layer of a Flash management protocol stack, to reduce transaction redundancy at abstracted layers. In some aspects, the common layer can be a block level layer providing relatively direct access to low level Flash. Thus, a file system or database application, operating at a higher, abstracted layer of the Flash management protocol stack, can offload transactioning operations to a block level process that has access to underlying Flash memory. As a result, increased efficiency, throughput, and added flexibility can be achieved for storage system transactioning.

Processes for identifying and recovering a lost transient storage device are provided. In some processes, information regarding the owner of the device is obtained. The device ownership information may be stored on a remote service with which the device is registered and/or may be stored on the device itself. In one process, the remote service provides the device with customized device-executable code when the device is registered. The device may also contain information regarding trusted systems. The process includes obtaining status information indicating whether a device is lost when the device is connected to a host system. In some processes, the status is determined by a remote service. In other processes, the status is determined by the device. If the device is lost then a device recovery plan is executed. Portions of a device recovery plan may be executed on the remote service, the host system, and/or the device.

Processes for presenting a current state of a device having device storage connected with a host system are provided. In some processes, device manufacturers or vendors define a set of operational states of a device and provide user interface (UI) elements of a custom representation of each state through information stored in the device storage. Initially, the set of states of the device and UI elements associated with each state are received from the device storage. Information regarding a current state is received from the device, and a representation of the current state, which includes the received UI elements, is presented on the host system. In other processes, UI elements of a representation of each state are obtained from a remote system using device identification information. In other processes, UI elements from the device, from the host system, and/or from a remote system are combined to form a state representation.
摘要:
A technology for enabling a plurality of devices to control each other is disclosed. In one method approach, a constellation is created by associating a plurality of devices with each other. At least one device that is associated with the constellation is used to control an activity associated with at least one other device that is associated with the constellation.

A method is provided for controlling a Mass Storage Class Digital Imaging Device using a SCSI pass through protocol. The protocol is based on industry standard SCSI protocol with modifications and extensions to allow transparent communication over a medium and is referred to as SCSI Pass Through (SPT). This protocol defines a set of commands that are initiated in a computer. The commands also include and extend industry standard Picture Transfer Protocol and are targeted for application and execution in a Mass Storage Class Digital Imaging Device. The invention includes the definition of data buffers in the form of data structures that can be used for packaging, passing, and receiving information related to the digital imaging device. The protocol is applicable to communication mediums that can be utilized in connecting any digital storage device to a computing device.
摘要:
A computer system and method uses script-based device drivers for operating hardware devices. The script-based driver architecture comprises a scripting driver, a script engine, and a driver script for a given hardware device, such as a scanner. The driver script is generally a text file containing a sequence of programming instructions defining the operational behavior of the hardware device. The scripting driver exports a set of objects whose functions can be called by the driver script to communicate with and control the device. When a request to operate the hardware device is received by the scripting driver, the script engine interprets the programming instructions in the driver script corresponding to the request and invokes the functions of the scripting driver objects called by the programming instructions to carry out the requested device operation.
