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: 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: 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: 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: 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.

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.

Abstract: An apparatus and method for determining signals representative of events in the environment of a reactive transducer while being driven by a switching amplifier is disclosed. While the switching amplifier is in a zero voltage state, a signal capture circuit that is also in a zero voltage state is connected to the transducer for a relatively brief period of time during which a measurement is made of the residual current flow due to the inductance of the transducer. A prediction of the output signal is then subtracted from the signal measured across the transducer, reducing the overall range of the signal and increasing the relative size of the back-EMF signal compared to any remaining output signal. If desired, conventional echo cancellation can then be performed. The back-EMF signal can then be subjected to further processing by an analog-to-digital converter as known in the art.

Abstract: A method for rendering computer graphics based on saccade detection is provided. One embodiment of the method includes rendering a computer simulated scene for display to a user, detecting an onset of a saccade that causes saccadic masking in an eye movement of the user viewing the computer simulated scene, and reducing a computing resource used for rendering frames of the computer simulated scene during at least a portion of a duration of the saccade. Systems perform similar steps, and non-transitory computer readable storage mediums each storing one or more computer programs are also provided.

Abstract: An analog element for use as a neuron in a recurrent neural network is described, the analog element having memory of a prior layer state and being a continuous time circuit rather than having a discrete clocking interval. The element is characterized and described by the Laplace s-domain operator, as distinct from a digital solution that uses the z-domain operator appropriate for quantized time descriptions. Rather than using an all-pass filter, the analog equivalent of a unit delay in the z-domain, a finite gain integrator, which is a simpler circuit, may be used to provide the delay in the analog s-domain. The resulting circuit may be easily implemented at the transistor level.

Abstract: An apparatus and method for performing a fast Fourier transform in the analog domain with passive components. A complex analog signal that is shift and scale invariant is derived from analog circuit properties. A butterfly circuit processes such signals using only passive components by mapping the Kirchhoff current and voltage laws into operations on the signals. A fast Fourier transform circuit of any desired width is constructed from such butterfly circuits. The passive networks require no power as the operations are on the presented signal; energy is taken from the source signal so no battery or power supply is needed. Thus, when the signal becomes quiescent, the power consumed is zero. Further there is no need of a clock or other timing device; rather, it is the operation of Kirchhoff laws in the network, which apply essentially upon arrival of the signal, that is made analogous to the desired operation.
