A packet processing technique can include receiving a packet, and parsing the packet based on a protocol field to generate a parse result vector. The parse result vector is used to select between forwarding the packet to a virtual machine executing on a host processing integrated circuit, forwarding the packet to a physical media access controller, multicasting the packet to multiple virtual machines executing on the host processing integrated circuit, and sending the packet to a hypervisor.

Personalized sensory services are provided to mobile devices. As a sensor monitors an area of surveillance, the sensor may detect a passing mobile device. The sensor may thus ally itself to the passing mobile device and provide personalized sensory operations.

Preventing applications from overconsuming shared storage resources, including: identifying one or more sub-regions of data stored on a storage device that are associated with an application of a known application type; compiling information describing the application's utilization of a storage system; determining that a storage system objective has not been met; and initiating, based on the information describing the application's utilization of the storage system, remediation actions.

A confidentiality preserving system and method for performing a rank-ordered search and retrieval of contents of a data collection. The system includes at least one computer system including a search and retrieval algorithm using term frequency and/or similar features for rank-ordering selective contents of the data collection, and enabling secure retrieval of the selective contents based on the rank-order. The search and retrieval algorithm includes a baseline algorithm, a partially server oriented algorithm, and/or a fully server oriented algorithm. The partially and/or fully server oriented algorithms use homomorphic and/or order preserving encryption for enabling search capability from a user other than an owner of the contents of the data collection. The confidentiality preserving method includes using term frequency for rank-ordering selective contents of the data collection, and retrieving the selective contents based on the rank-order.

A data acquisition apparatus (200) comprises a processing resource operably coupled to an input unit (204) and an output unit (206). The processing resource (202) is arranged to provide an execution environment for supporting a user interface. An enquiry module (268) is provided and supported by the execution environment. The apparatus (200) also comprises a communications unit (166, 168) operably coupled to the processing resource for supporting communications over a communications network. The enquiry module (268) is arranged to generate (410) a search query relating to a point of interest and receive search results in response thereto via the communications unit (166, 168), the enquiry module (268) also being arranged to use the search results to derive data associated with the point of interest.

Systems and methods for file management by mobile computing devices. An example method, performed by a computer system, may comprise: storing, by a computer system, a first file having a first size, in a memory; storing, in the memory, a second file derived from the first file, the second file having the second size, the second size being less than the first size; determining that the memory is not sufficient to perform a memory write operation; selecting a third file having a fourth file associated with it, the fourth file derived from the third file; and removing the third file from the memory.

Methods and systems are disclosed for tracking change data in a database. A database, stored at a computer system, is accessed with a plurality of data written to fields in the database, wherein each data in the fields comprises a record header. Data is changed in at least one field of the plurality of data in the database via the computer system, wherein the changing the data changes the record header for the at least one field. A transaction identification (ID) is stored in the record header for each change to the at least one field. A flag is created in the record header signaling the change to the at least one field. Successive versions of the database are linked together such that a subscriber accessing the database can automatically view a current version of the database with the change by accessing the record header and identifying the flag.

Disclosed are a method and a system for detecting a touch pattern width and identifying the touch pattern, including receiving, from a touch device, first coordinate information and corresponding touch width information for a touch pattern, and storing the first coordinate information and the touch width information, receiving, from an operating system, second coordinate information for a current touch pattern, and searching, from the stored first coordinate information, for one consistent with the second coordinate information, and determining the touch width information corresponding to the first coordinate information that has been found as width information of the current touch pattern.
