The discussion relates to inventory control. In one example, a set of ID sensors can be employed in an inventory control environment and subsets of the ID sensors can collectively sense tagged items in shared space. Data from the subset of ID sensors can indicate when a user has taken possession of an individual tagged item in the shared space.

Inventory control

The discussion relates to context-aware environments. One example can include inwardly-facing cameras positioned around a periphery of an environment that defines a volume. The example can also include sensors positioned relative to the volume and configured to communicate with a user device in the volume. The example can also include an ambient perception component configured to track user locations in the volume and to detect user gestures relative to objects in the volume, and responsive to receiving a query from the user's device, to supplement the query with information derived from the objects.

Context-awareness

The disclosure relates to tracking the location of a target object. In one example, a computer vision system detects a configuration of environment objects. A location model that has been trained for the environment configuration is selected. A signal associated with the target object is received and interpreted using the selected location model to determine the location of the target object.

Location tracking

The described method and system enables a client at a branch office to retrieve data from a local hosted cache instead of an application server over a WAN to improve latency and reduce overall WAN traffic. A server at the data center may be adapted to provide either a list of hashes or the requested data based on whether a hosted cache system is enabled. A hosted cache at the client side may provide the data to the client based on the hashes. The hashes may be generated to provide a fingerprint of the data which may be used to index the data in an efficient manner.

Method and system of using a local hosted cache and cryptographic hash functions to reduce network traffic

A system for preventing quality of service policy abuse comprising a media connection and a local area network prioritizing quality of service in which quality of service to a to a video receiver or similar device may be maintained by prioritizing its signal relative to other signals competing for network bandwidth.

Preventing quality of service policy abuse in a network

An access control mechanism in a network connecting one or more sink devices to a server providing audio/visual data (A/V) in streams. As a sink device requests access, the server measures available bandwidth to the sink device. If the measurement of available bandwidth is completed before the sink device requests a stream of audio/visual data, the measured available bandwidth is used to set transmission parameters of the data stream in accordance with a Quality of Service (QoS) policy. If the measurement is not completed when the data stream is requested, the data stream is nonetheless transmitted. In this scenario, the data stream may be transmitted using parameters computed using a cached measurement of the available bandwidth to the sink device. If no cached measurement is available, the data stream is transmitted with a low priority until a measurement can be made. Once the measurement is available, the transmission parameters of the data stream are re-set. With this access control mechanism, A/V streams may be provided with low latency but with transmission parameters accurately set in accordance with the QoS policy.

Quality of service support for A/V streams

A computer system that implements a quality of service policy. Information defining the quality of service policy is stored in a central location, such as a server within an enterprise. Policy management software on clients in the network download quality of service policy information from the central location to the clients. Within a client, a portion of the policy information is selected based on its applicability to a particular connection. The selected information is cached with an association to the connection so that, as datagrams are generated for transmission over the network, relevant policy information is quickly accessed for use in controlling transmission characteristics of datagrams sent using that connection. Additionally, time information may be associated with information in the cache as well as policy information available from the server. Whenever a datagram is to be transmitted over a connection associated with out-of-date policy information in the cache, the cache information is updated.

Network supporting centralized management of QoS policies

To improve upon existing Winsock implementations, the claimed system and method adapts an existing Winsock system to use out-of-process NSP services. The claimed method and system provides asynchronous Winsock Next calls to provide client application processing flexibility. Further, the claimed method and system provides additional structures for passing additional NSP specific information for a result set to enable further client functionality. One embodiment of the claimed system provides additional client Winsock API functions to aggregate and manage asynchronous calls to multiple NSPs and/or multiple namespaces.

Winsock APIs

A method and system for directing data transfers between applications and devices residing on different computers or devices using an adaptive flow control protocol has been described. When an application or device requests to transfer data with another application or device, adaptive flow control protocol adapts the way data is transferred by observing when an application that is receiving data posts a receive buffer and detects the receive buffer's size. Based upon the application's or device's behavior, the adaptive flow control protocol transfers the data in a mode that is best suited for the application.

Adaptive flow control protocol and kernel call handling

An API enables an application to make a single call for a send operation to an operating system that results in a multicast communication. The API may provide the ability to define a socket group including one or more sockets, in which each socket represents a respective network connection to another network device. An application may utilize the socket group when calling to the operating system with a send operation, by specifying an identifier (i.e., a handle) of the socket group to the operating system. Based on the socket group identifier, the operating system may control sending multiple instances of a communication to the network devices corresponding to the connections represented by the sockets of the socket group. Tasks that are repeated for every destination of a multicast in known systems may be performed only once, reducing CPU utilization and making applications that use multicasting more scalable.
