摘要： Implementations selectively offload visual frames from a client device to an edge system for processing. The client device can receive streaming visual frames and a request to process the visual frames using a data service. The client device can offload visual frames to an edge system preloaded with a workload resource that corresponds to the requested data service. After the edge system processes the offloaded visual frames using the workload resource, the edge system can return the processed visual frame to the client device. In some implementations, the edge system and client device are situated in a network such that a latency for the offload communications support real-time video display. A cloud system can maintain a registry of edge systems and provide client devices with information about nearby edge systems. The cloud system can also preload the edge systems with workload resources that correspond to data services.

摘要： In one embodiment, a computing system may determine, for a pixel, a sampling location within a texture that comprises a plurality of texels, and based on the sampling location, select a set of texels in the plurality of texels. Each texel in the set of texels may encode a distance field. An interpolated distance field associated with the sampling location may be computed based on the distance fields associated with the set of texels. The interpolated distance field may represent a relative distance between the sampling location and a texture edge. According to a blending proportion based on the interpolated distance field, the computing system may determine a blended color for the sampling location by blending, a first and second color associated with a first side of the edge and a second side of the edge, and output a color for the pixel based on the blended color.

摘要： An optically anisotropic polymer thin film includes a crystallizable polymer and an additive configured to interact with the polymer (e.g., via π-π interactions) to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 50% of the molecular weight of the crystallizable polymer. Example crystallizable polymers include polyethylene naphthalate, polyethylene terephthalate, polybutylene naphthalate, polybutylene terephthalate, as well as derivatives thereof. Example additives, which may occupy up to approximately 10 wt. % of the polymer thin film, include aromatic ester oligomers, aromatic amide oligomers, and polycyclic aromatic hydrocarbons, for example. The optically anisotropic polymer thin film may be characterized by a refractive index greater than approximately 1.7 and an in-plane birefringence greater than approximately 0.2.

摘要： Disclosed herein are related to a first device to communicate with a second device and a third device. In one aspect, the first device determines a first time interval to receive a first beacon frame from the second device. In one aspect, the first device determines, according to the first time interval, a second time interval for the first device to transmit a second beacon frame to a third device. In one aspect, the first device determines a third time interval to operate the first device in a wake up mode. The third time interval may encompass the first time interval and the second time interval. In one aspect, the first device receives the first beacon frame from the second device during the first time interval, and transmits the second beacon frame to the third device during the second time interval.

摘要： A emitting diode (LED) includes an epitaxial structure defining a base and a mesa on the base. The base defines a light emitting surface of the LED and includes current spreading layer. The mesa includes a thick confinement layer, a light generation area on the thick confinement layer to emit light, a thin confinement layer on the light generation area, and a contact layer on the thin confinement layer, the contact layer defining a top of the mesa. A reflective contact is on the contact layer to reflect a portion of the light emitted from the light generation area, the reflected light being collimated at the mesa and directed through the base to the light emitting surface. In some embodiments, the epitaxial structure grown on a non-transparent substrate. The substrate is removed, or used to form an extended reflector to collimate light.

摘要： A method for training a real-time, direct clothing modeling for animating an avatar for a subject is provided. The method includes collecting multiple images of a subject, forming a three-dimensional clothing mesh and a three-dimensional body mesh based on the images of the subject, and aligning the three-dimensional clothing mesh to the three-dimensional body mesh to form a skin-clothing boundary and a garment texture. The method also includes determining a loss factor based on a predicted cloth position and garment texture and an interpolated position and garment texture from the images of the subject, and updating a three-dimensional model including the three-dimensional clothing mesh and the three-dimensional body mesh according to the loss factor. A system and a non-transitory, computer-readable medium storing instructions to cause the system to execute the above method are also provided.

摘要： Disclosed herein includes a system, a method, and a device for multiply-accumulate operation. In one aspect, an input operand is received by control circuitry. In one aspect, the control circuitry determines a sparsity of the input operand, where the sparsity may indicate whether a value of the input operand has a predetermined value or not. In one aspect, the control circuitry determines a stationarity of the input operand, where the stationarity may indicate whether the value of the input operand changes over one or more clock cycles. In one aspect, the input operand is provided to multiply-accumulate circuitry as an input, according to the determined sparsity and stationarity of the input operand.

摘要： This disclosure describes an artificial reality system that presents artificial reality content or artificial reality effects based on, or in response to, interactions with one or more physical objects within a physical environment. In one example, this disclosure describes a method that includes determining that a user has performed a trigger action on a trigger object; responsive to determining that the user has performed the trigger action, generating artificial reality content; presenting the artificial reality content on a display associated with a head-mounted display; determining that the user has performed a de-trigger action; and responsive to determining that the user has performed the de-trigger action, discontinuing presentation of the artificial reality content.

摘要： Ghost image formation due to reflections of image light by a display panel to an ocular lens may be suppressed by ensuring that the image light reflected by the lens does not get reflected by the display panel back towards the lens. To that end, the display panel may include a quarter-wave birefringent layer between the top polarizer of the display panel and a layer inside the display panel that the image light reflects from, such as a black grid layer or an active matrix layer.
