Described herein is a system for executing distributed transactions. A coordinator and one or more participants cooperate to execute a distributed transaction, the distributed transaction including for each participant a transaction executed by the participant. To manage the transaction, the coordinator and the participant communicate over a network using, for example, a stateless protocol. Before each participant commits the transaction, the participants determine that the coordinator has committed the transaction. The coordinator commits the transaction after receiving acknowledgment from all the participants that they will commit the transaction. To determine whether the coordinator has committed the transaction, a participant transmits a message to the coordinator to acknowledge that it will commit the distributed transaction. The participant commits its respective transaction if it receives an acknowledgement from the coordinator. For the particular transaction being executed by a participant, the participant prevents other transactions from modifying a data item affected by the particular transaction. The participant will prevent such modifications until termination criteria for the particular transaction is satisfied, in which case the participant terminates the transaction.

A non-transitory computer-readable storage medium stores one or more programs including instructions, which when executed by an electronic device, cause the electronic device to receive natural-language speech input from one of a plurality of users, the natural-language speech input having a set of acoustic properties; and determine whether the natural-language speech input corresponds to both a user-customizable lexical trigger and a set of acoustic properties associated with the user; where in accordance with a determination that the natural language speech input corresponds to both a user-customizable lexical trigger and a set of acoustic properties associated with the user, invoke a virtual assistant; and in accordance with a determination that either the natural language speech input fails to correspond to a user-customizable lexical trigger or the natural-language speech input fails to have a set of acoustic properties associated with the user, forego invocation of a virtual assistant.

An architecture and system are described that provide a unified file access service within in a managed computing environment composed of diverse networks, computing devices, and storage devices. The service provides mechanisms for remotely accessing the file systems of any managed computer or disk snapshot, independently of the computer's current state (powered on, suspended or powered off), its location within the environment, its hardware type (virtual vs. physical), its operating system type, and its file system formats. The system isolates centralized FPAs from the details of clients, proxies and storage elements by providing a service that decomposes offloaded file system access into two steps. A FPA or a requester acting on behalf of the FPA first expresses the disk set or the computer containing the file systems it wishes to access, along with requirements and preferences about the access method. The service figures out an efficient data path satisfying the FPA's needs, and then automatically configures a set of storage and computing resources to provide the data path. The service then replies with information about the resources and instructions for using them. The FPA then accesses the requested file systems using the returned information.

Described herein is a system for executing distributed transactions. A participant and a coordinator cooperate to execute a distributed transaction, the distributed transaction including a transaction executed by the participant. To manage the transaction, the coordinator and the participant communicate over a network using, for example, a stateless protocol. The distributed transaction may be terminated when communication between the participant and coordinator regarding the transaction does not occur within a time period. The time period may reflect the time required for a coordinator to send a message and a participant to acknowledge receipt of the message, and the time for the participant to perform operations executed for the transaction. The latency of network traffic between the participant and the coordinator is monitored, and the time periods adjusted accordingly. In addition, the amount of time required for the participant to execute operations for the transaction is monitored, and the time periods adjusted accordingly.

A vehicle monitoring apparatus for obtaining a distance image including an image data and three-dimensional distance information and for monitoring surrounding conditions on the basis of the distance image, comprises: means for dividing the distance image into a plurality of blocks composed of picture elements, means for collecting the blocks having a similar distance data and for grouping the blocks into an independent group, means for calculating an area size of the independent group, means for extracting the image data as an object data if the area size of the group is larger than a predetermined value and for discarding the image data as a false data if the area size is smaller than the predetermined value, means for preparing a histogram having a lateral axis representing a deviation amount and a longitudinal axis representing a frequency corresponding to a number of the image data, and means for detecting an object and a distance to the object by deleting the frequency having a smaller number of the image data than a threshold value along the lateral axis on the histogram. Thereby, false data can be removed from the image data and a mismatching can be prevented.

The invention provides a system and a method for data input that can be used with or incorporated into electronic, computer, and portable devices. The interface includes a small set of control buttons or keys that are used to provide access to an associated set of secondary keys, from which the user can select a character for input into the device. Intelligent ordering and grouping of the control and secondary keys allows the user to input information in a manner conducive to speed, accuracy, and ease of use, while the interface can be minimized to require less real estate than traditional keyboards. In accordance with one embodiment, a set of characters or symbols is divided into subsets, each subset being represented by a control button. Selecting a control button displays a secondary set of buttons representing actual characters or symbols that can be selected, stored, or displayed.
