Abstract: A session management involves registering at least one IPTV application in a registration table so that the registration table includes at least a respective identifier of the IPTV applications. The IPTV applications are invokable at a set top box and can be so-called embedded applications and/or browser-based applications. An event requiring the invocation of an IPTV application at the set top box is detected and triggers a look-up in the registration table. The registration table is thus used as source to indicate those IPTV applications that are potentially available and can be launched at the set top box. One of the registered applications is launched for the purpose of handling the detected event.

Abstract: An apparatus and method for voice activity detection. A multiphase differential output rotating capacitive sampler achieves a frequency down conversion over as many specific frequency bands as are required for analysis. A chirp is created in the rotating sampler as the sum of arbitrary frequencies across the desired analysis band multiplied by a window function. The chirp is sampled at a rate of rotation synchronous with the last state of burst of the chirp, allowing a non-phase synchronous pattern in the coefficient values and allowing a high-Q and arbitrary decomposition of the signal. After the sample is taken, the next clock signal to the sampler is used to define the output voltage of the sampler by shorting the output, which is entirely capacitive, to ground. Processing occurs in the analog domain rather than digitally, avoiding the need for FFTs and allowing for greater speed and lower power consumption.

Abstract: Combinatorial logic circuits with feedback, which include at least two combinatorial logic elements, are disclosed. At least one of the combinatorial logic elements receives an external input (i.e., from outside the circuit), at least one of the combinatorial logic elements receives an input that is feedback of the circuit output, and at least one of the combinatorial logic elements receives an input that is neither an external input nor an output of the circuit but rather is from another of the combinatorial logic elements and thus only “implicit” to the circuit. No staticizers are needed; the logic circuits effectively create implicit equations to perform functions that were previously thought to require sequential logic. The combinatorial logic circuits result in a stable output (in some instances after a brief period of time) due to the implicit equations, rather than achieving stability from an explicit expression of some input to the circuit.

Abstract: Methods for tagging content in a video game title during game play executed on a game cloud system, and social sharing methods. One method includes receiving a pause indication during the game play and suspending the game play to hold the video game title in a current frame image, storing the game state, and receiving the tag data that is associated to a location in the current frame image and to a user identifier for the current frame image. The method further includes generating a video recording of the game play having the tag data and generating a mini-game from a portion of the video game title. The mini-game includes a playable portion to enable view of a portion of the video recording for the mini-game and an executable portion to enable the play of game code for the mini-game that is a portion of the video game title.

Abstract: Methods and systems for facilitating authentication of a user with a plurality of applications are described. One method includes authenticating a user with a first secure application based on information received from a smart credential stored on a mobile device via a local wireless connection. The method includes obtaining a remote challenge from a remote authentication service and a mobile challenge, signing the mobile challenge with a private key, and transmitting a signed version of the mobile challenge, the remote challenge, and a public key to the mobile device. The method further includes receiving a signed version of the remote challenge and a certificate indicating validation of the mobile challenge, and transmitting the signed version of the remote challenge to the remote authentication service. Based on receiving an authentication result from the remote authentication service, access is granted to a remote secure application via the browser.

Abstract: An apparatus and method for improving the efficiency of a D class amplifier, particularly at lower output levels. A class D amplifier having a load with inductance, such as a transducer, is configured to concurrently act as its own buck regulator. A capacitor connected to ground and to both ends of the transducer through switches functions as the buck regulator in connection with the inductance of the transducer, providing the class D amplifier with additional voltage levels such as might be provided by a G/H class amplifier but without the added complexity or expense of the G/H configurations. Better efficiency is possible than that provided by a 100% efficient conventional buck regulator. No envelope detector is required, nor any change to the gain of the digital signal to the class D amplifier. Feedback may be used if desired, but is not required to obtain a high quality output signal.

Abstract: A medical tube transports gases to and/or from a patient. The medical tube has an elongate film spirally wrapped with an elongate reinforcing member, which bond to form a lumen. The elongate film has a profile such that the elongate film does not protrude into the lumen of the medical tube upon bending of the medical tube. The elongate reinforcing member can have a D-shaped cross section that can contribute to beneficial characteristics of the medical tube. The elongate reinforcing member can also have a circular cross section.

Abstract: A room manager can generate mappings for a real-world room that support a shared XR environment. For example, the real-world room can include real-world objects and surfaces, such as a table(s), chair(s), wall(s), door(s), window(s), etc. The room manager can generate XR object definitions based on information received about the real-world room, object(s), and surface(s). For example, the room manager can implement a flow that guides a user equipped with an XR system to provide information for the XR object definitions, such as real-world surfaces that map to the XR object(s), borders (e.g., measured using a component of the XR system), such as borders on real-world surfaces, semantic information (e.g., number of seat assignments at an XR table, size of XR objects, etc.), and other suitable information. Implementations generate previews of the shared XR environment, such as a local preview and a remote preview.

Abstract: Aspects of the present disclosure are directed to creating and administering artificial reality collaborative working environments and providing interaction modes for them. An XR work system can provide and control such artificial reality collaborative working environments to enable, for example, A) links between real-world surfaces and XR surfaces; B) links between multiple real-world areas to XR areas with dedicated functionality; C) maintaining access, while inside the artificial reality working environment, to real-world work tools such as the user's computer screen and keyboard; D) various hand and controller modes for different interaction and collaboration modalities; E) use-based, multi-desk collaborative room configurations; and F) context-based auto population of users and content items into the artificial reality working environment.

Abstract: Disclosed herein are methods and compositions for a new way to separate biologics using coated pegboards—plastic plates affixed with an array of 96-pegs which align with the wells of a traditional 96-well plate used in bench top experiments. The ends of the pegs are conjugated to various compounds which are able to bind tags on engineered proteins (ex. Ni-NTA would bind a His-Tag on an engineered protein). These pegs extend into plate wells to specifically bind the tagged protein from the cell lysate which contains hundreds of other proteins. The pegboard, now laden with the protein of interest (POI), may then be dipped into sequential buffers to wash away potential non-specifically bound proteins to purify the POI.

Abstract: A method for method for classification of virtual reality (VR) content for use in head mounted displays (HMDs). The method includes accessing a model that identifies a plurality of learned patterns associated with the generation of corresponding baseline VR content that is likely to cause discomfort. The method includes executing a first application to generate first VR content. The method includes extracting data associated with simulated user interactions with the first VR content, the extracted data generated during execution of the first application. The method includes comparing the extracted data to the model to identify one or more patterns in the extracted data matching at least one of the learned patterns from the model such that the one or more patterns are likely to cause discomfort.

Abstract: A session management involves registering at least one IPTV application in a registration table so that the registration table includes at least a respective identifier of the IPTV applications. The IPTV applications are invokable at a set top box and can be so-called embedded applications and/or browser-based applications. An event requiring the invocation of an IPTV application at the set top box is detected and triggers a look-up in the registration table. The registration table is thus used as source to indicate those IPTV applications that are potentially available and can be launched at the set top box. One of the registered applications is launched for the purpose of handling the detected event.

Abstract: Provided are improved machine learning-based text editing models. Specifically, example implementations include a flexible semi-auto-regressive text-editing approach for generation, designed to derive the maximum benefit from non-auto-regressive text-editing and autoregressive decoding. In contrast to conventional sequence-to-sequence (seq2seq) models, the proposed approach is fast at inference time, while being capable of modeling flexible input-output transformations.
