摘要:
A system comprises a PC and a plurality of personal digital devices, each device to store one of a plurality of sets of credentials in an internal secured storage area. A method of managing a constellation of trusted devices comprises coupling a device with the PC, adding the device to the constellation if the device is not a member of the constellation, and transmitting the set of credentials from the PC to the internal secured storage area if the device does not have the credentials. A method of enabling communication between devices comprises coupling a first personal digital device with a second personal digital device, validating both devices, authenticating both devices, and prompting both devices to couple with the PC to become members of the constellation and obtain new sets of credentials if both devices are not authenticated and validated.

Various technologies and techniques are disclosed that improve synchronization of data between varying types of devices and/or services. A full participant receives a request from another participant to perform a synchronization operation. The synchronization engine determines whether the device or service is a full, partial, or simple participant. The device or service is a simple participant if it has a data store for synchronized data and no knowledge store. The device or service is a partial participant if it has a data store for synchronized data and a knowledge store, but does not understand the knowledge. The device or service is a full participant type if it has a data store for synchronized data and a knowledge store and understands the knowledge. The synchronization engine performs the synchronization operation with the device or service using a set of logic that is appropriate for the type of device or service.
摘要:
A computer system uses simplified device drivers for operating hardware devices. A simplified device driver for a hardware device of a given device type, such as a flatbed scanner, works with a system-supplied common driver for that given device type. The common driver and the simplified driver together function like a regular device driver. The simplified device driver implements a small number of entry point functions corresponding to a pre-selected set of operation commands “generic” to hardware devices of that given device type. When an application makes a request for an operation by the device, the request is passed through a device driver interface (DDI) to the common driver. The common driver then calls the entry point functions in the simplified device driver to carry out the requested operation.

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 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:
Described herein are one or more implementations for exposing data content (e.g., digital media) of a portable digital media device over a network to one or more network-connected electronics devices, where such exposing is done via a network-connected personal computer to which the portable digital media device is directed coupled (e.g., via a USB). Also, described herein are one or more implementations for gathering a customized collection of data content from web-feeds at a web-connected personal computer and exposing that gathered web-feed data content to a network-connected electronics devices (such as a set-top box for a television).
摘要:
A system and related techniques generate an interrogation request from an initiator device, such as a client desktop machine or other machine, to a mobile or other media player, such as a digital camera, MP3 player, video camera or other device or hardware to enumerate the media content contained in that device, along with associated properties. The collection of binary objects which encode the content, such as digital photographs, encoded audio files, digitized video or other media, may include or have associated with them a set of corresponding object properties which help to define each object, such as by defining a pixel color depth, audio codec or other property or attribute. According to embodiments of the invention, the initiator may communicate with the responding device using a media-aware protocol supporting an aggregate object property request, such that the initiator may identify one or all of the set of properties paired with all of the objects to be returned along with an enumeration of those objects. The initiator may then present, for example, a list of song titles along with the corresponding artist, track length, codec, display skins or other attributes or properties to a user, for example to select, delete, copy or otherwise manipulate the underlying objects, which may in one regard be separately retrieved from their identifier and properties. Because properties may be retrieved in conjunction with, at the same time and using a unified retrieval scheme, the need to query each object identifier one by one for associated properties is removed. The throughput and responsiveness of object property retrieval is therefore significantly enhanced.
摘要:
Methods and a computing device are disclosed. A computing device may include a managed device having embedded firmware. When a failure occurs with respect to the managed device, drivers within the computing device may collect failure data from a driver stack of the computing device and from the managed device. The computing device may send the collected failure data to one or more second computing devices to be stored and analyzed. The computing device may include a health monitor for periodically collecting telemetry data from the computing device and the managed device. When the health monitor becomes aware of conditions indicative of a possible impending failure, the health monitor may trigger collection of sickness telemetry data from the computing device and the managed device. Collected data from the managed device may be made available to a vendor of the managed device.
摘要:
Methods and devices are provided for adapting an I/O pattern, with respect to a processing device using a non-volatile block storage device based on feedback from the non-volatile block storage device. The feedback may include information indicating a status of the non-volatile block storage device. In response to receiving the feedback, a storage subsystem, included in an operating system executing on processing device, may change a behavior with respect to the non-volatile block storage device in order to avoid, or reduce, a negative impact to the non-volatile block storage device or to enhance an aspect of the non-volatile block storage device. The feedback may include performance information and/or operating environmental information of the non-volatile block storage device. When the non-volatile block storage device is not capable of providing the feedback, the processing device may request information about the non-volatile block storage device from a database service.
