Abstract: A voltage mode laser diode driver selectively turns on and off a laser diode. An output stage has an output node configured to be connected to one of the terminals of the laser diode. Depending upon implementation, an active swing controller drives the output stage in a manner that substantially prevents inductive kickback from causing the output node voltage to swinging above the voltage level at the voltage output of the power supply, or swing below ground. The output stage provides a discharge path around the laser diode to shunt current associated with the inductive kickback, and substantially eliminates ringing on the output node of the output stage while the laser diode is off. A power supply controller adjusts the voltage level of the voltage output of the power supply so that current through the laser diode when on and emitting light is substantially equal to a predetermined desired current.

Abstract: Analysis of incomplete natural language expressions using n-gram analysis and contextual information allows one or more domains to be predicted. For each domain, intent a likely intent of the user is determined using n-gram analysis and contextual information. Intent may correspond to functions of a domain application. In such a case, information required for the functions to execute the application may be populated using n-gram analysis and/or contextual information. The application may then be presented to the user for confirmation of intent. Confirmation of intent along with the incomplete natural language expression and contextual information may then be used to train one or more models used to predict user intent based on incomplete natural language expressions.

Abstract: Systems and methods for responding to spoken language input or multi-modal input are described herein. More specifically, one or more user intents are determined or inferred from the spoken language input or multi-modal input to determine one or more user goals via a dialogue belief tracking system. The systems and methods disclosed herein utilize the dialogue belief tracking system to perform actions based on the determined one or more user goals and allow a device to engage in human like conversation with a user over multiple turns of a conversation. Preventing the user from having to explicitly state each intent and desired goal while still receiving the desired goal from the device, improves a user's ability to accomplish tasks, perform commands, and get desired products and/or services. Additionally, the improved response to spoken language inputs from a user improves user interactions with the device.

Abstract: Techniques including use of a slider cover for a computing device are described. In one or more implementations, the slider cover includes a cover body and a pair of hinge assemblies secured along opposing edges of the cover body. The hinge assemblies are designed to attach to a housing for a computing device having a pair of tracks extending along opposing edges of the housing. Engagement of the tracks with the hinge assemblies forms an attachment of the housing to the slider cover designed to enable the housing and slider cover to slide relative to one another in parallel planes and the housing to pivot around a pivot axis formed by the pair of hinge assemblies. Accordingly, manipulation of the housing relative to the slider cover may occur via the hinge assemblies to assume multiple different configurations for an apparatus that includes the slider cover.

Abstract: Methods, systems, apparatuses, and computer program products are provided for detecting objects, including humans, using a mobile communications device. A communication space is scanned with a beam-shaped signal transmitted by a phased antenna array of the mobile communications device. Information is discerned from one or more attenuated signals received from the communication space based on the beam-shaped signal. The information is analyzed to determine an object in the communication space. Whether the object is likely at least a portion of a human is determined. A communication signal transmitted by the phased antenna array is modified in response to determining that the object is likely at least a portion of a human, and that the at least a portion of the human has a predetermined spatial relationship with the phased antenna array.

Abstract: Implementations of accessible content reputation lookup are described. In one implementation, before a user activates a link in a document, such as a hyperlink on a webpage, the user can designate the link. For example, the user can float a cursor over the link or interact with an icon placed proximate to the link. By designating the link, the user can request reputation information associated with the link, including information as to whether or not content associated with the link, an application used to access the content, and/or source(s) on which the content resides, are known to be dangerous or risky. If the reputation information indicates that the link is safe to activate, the user can activate the link and access the content. Alternately, if the reputation information indicates that the link is unsafe to access, the user can choose to forego activation of the link.

Abstract: An electronic device provides a detuning monitor circuit configured to detect a change in a voltage standing wave ratio (VSWR) between a radio frequency (RF) transmitter and an RF antenna relative to a predetermined VSWR baseline and a proximity detector circuit configured to adjust transmission power of a carrier wave transmitted from the RF transmitter, if the change fails to satisfy an acceptable VSWR condition. Network proximity detectors are also provided to allow coordination of antenna subsystems to comply with specific absorption rate (SAR) constraints and/or maintain/improve antenna performance.

Abstract: A “Point Cloud Smoother” provides various techniques for refining a 3D point cloud or other 3D input model to generate a smoothed and denoised 3D output model. Smoothing and denoising is achieved, in part, by robustly fitting planes to a neighborhood of points around each point of the input model and using those planes to estimate new points and corresponding normals of the 3D output model. These techniques are useful for a number of purposes, including, but not limited to, free viewpoint video (FVV), which, when combined with the smoothing techniques enabled by the Point Cloud Smoother, allows 3D data of videos or images to be denoised and then rendered and viewed from any desired viewpoint that is supported by the input data.
