Abstract:
Apparatus and methods for automatic service discovery and connectivity include acts of or components for retrieving service metadata associated with one or more service devices from a connectivity entity, wherein the service metadata comprises connectivity parameters, and configuring one or more links with at least one of the one or more service devices based on the service metadata. Further, the apparatus and methods may include acts of or components for using a service available from the one or more service devices through the one or more links.
Abstract:
Methods and apparatuses are provided for facilitating group access controls in peer-to-peer or other similar overlay networks. A group administrator may create a group in the overlay network and may assign peer-specific certificates to each member of the group for indicating membership in the group. A group member peer node can access data objects in the overlay network using its respective peer-specific certificate to authenticate itself as a group member. The authentication is performed by another peer node in the network. The validating peer node can authenticate that the group member is the rightful possessor of the peer-specific certificate using a public key associated with the peer node to which the peer-specific certificate was issued. The validating peer node can also validate that the peer-specific certificate was properly issued to the group member using a public key of the apparatus that issued the peer-specific certificate.
Abstract:
Methods, systems, computer-readable media, and apparatuses for determining indoor/outdoor state of a mobile device are presented. In some embodiments, a sensor reading is obtained from a sensor accessible by the mobile device. Contemporaneous information related to a local condition associated with an area where the mobile device is located is obtained. The sensor reading is provided as input to an indoor/outdoor detection model selected from a plurality of trained models, selected on the basis of the information related to the local condition. Based on the output of the model, the mobile device is classified as indoors or outdoors.
Abstract:
Systems, apparatus and methods in a mobile device to enable and disable a depth sensor for tracking pose of the mobile device are presented. A mobile device relaying on a camera without a depth sensor may provide inadequate pose estimates, for example, in low light situations. A mobile device with a depth sensor uses substantial power when the depth sensor is enabled. Embodiments described herein enable a depth sensor only when images are expected to be inadequate, for example, accelerating or moving too fast, when inertial sensor measurements are too noisy, light levels are too low or high, an image is too blurry, or a rate of images is too slow. By only using a depth sensor when images are expected to be inadequate, battery power in the mobile device may be conserved and pose estimations may still be maintained.
Abstract:
Systems and methods for monitoring the number of neighboring wireless devices in a wireless network are described herein. In one aspect, the method includes receiving a message from one of the neighboring wireless devices having an identifier associated with the neighboring wireless device and adding the identifier into a Bloom filter. The method may further include estimating the number of distinct strings that have been added into the Bloom filter based on the number of zeros in the Bloom filter, the number of distinct strings representing an estimate of the number of neighboring wireless devices in the wireless network.
Abstract:
Disclosed are systems and methods for providing a rules engine as a platform within a portable electronic device. In one embodiment, a rules engine platform is provided within a portable electronic device by receiving a plurality of rules for one or more modules of the portable electronic device. Additionally, the rules engine platform can receive one or more samples from one or more of the modules within the portable electronic device. The rules engine platform identifies and evaluates one or more relevant rules based on the received sample. The rules engine platform can then determine an action to provide to other modules of the portable electronic device. The rules engine platform may be configured to optimize the performance and power consumption of the portable electronic device.

Abstract:
A mobile platform efficiently processes sensor data, including image data, using distributed processing in which latency sensitive operations are performed on the mobile platform, while latency insensitive, but computationally intensive operations are performed on a remote server. The mobile platform acquires sensor data, such as image data, and determines whether there is a trigger event to transmit the sensor data to the server. The trigger event may be a change in the sensor data relative to previously acquired sensor data, e.g., a scene change in an image. When a change is present, the sensor data may be transmitted to the server for processing. The server processes the sensor data and returns information related to the sensor data, such as identification of an object in an image or a reference image or model. The mobile platform may then perform reference based tracking using the identified object or reference image or model.
Abstract:
A latching element (124) latches incoming data (D(7:0)) into an integrated circuit (101). The latching element (for example, a latch or flip-flop) can be considered to include a data path portion (126), a clock path portion (127), and an ideal latching element (125). In one embodiment, an open-loop replica (118) of the data path portion (126) is disposed in a clock signal path between a clock input terminal (116) of the integrated circuit and a clock input lead (130) of the latching element. In a second embodiment, an additional replica (144) of the clock path portion is disposed in a data signal path between a data terminal (105) of the integrated circuit (101) and a data input lead (128) of the latching element. The replica circuits (118,144) help prevent changes in skew between a data path propagation time to the ideal latching element and clock path propagation time to the ideal latching element. Setup times remain substantially constant over PVT (process, supply voltage, temperature).
