US11272025B2 HTTP-based stream delivery
Stream delivery within a content delivery network (CDN) includes recording the stream using a recording tier, and playing the stream using a player tier. Recording begins when the stream is received in a source format. The stream is then converted into an intermediate format (IF), which comprises a stream manifest, one or more fragment indexes (FI), and a set of IF fragments. A player process begins when a requesting client is associated with a CDN HTTP proxy. In response to receipt at the proxy of a request for the stream, the HTTP proxy retrieves (either from the archive or the data store) the stream manifest and at least one fragment index. Using the fragment index, the IF fragments are retrieved to the HTTP proxy, converted to a target format, and then served in response to the client request. Preferably, fragments are accessed, cached and served by the proxy via HTTP.
US11272023B1 Parental monitoring of multiplayer game chat
A background application running on a child computing device periodically takes screenshots which are samples of what the child is viewing. If the child is playing a video game, text can be extracted from the screenshot within areas of the screen that chat is known to be displayed for the particular game. A cloud computing platform provides services for machine learning (ML) to analyze the chat text to ascertain a likelihood that the chat includes bullying or sexual predation. If it appears likely, the game is disabled and a notification is sent to a parental monitoring application along with a copy of the offensive chat. The parent can override the determination, and in this case, the user application running on the child computing device is re-enabled. The parent's action either to override the determination or to let it stand is then fed back to the ML model so that the ML model continues to learn the semantics of in-game chat based on the parental feedback.

The photovoltaic device may include a semiconductor layer epitaxially grown using a compound semiconductor material, such as a group III-V semiconductor material, wherein a surface of the semiconductor layer is textured via one or more laser pulses of a laser. The photovoltaic device may also include a dielectric layer deposited over the textured surface of the semiconductor layer, and a back metal reflector provided on the dielectric layer. The textured surface extends a path of light traveling through the photovoltaic device to increase absorption of the light within the photovoltaic device.
US11271120B2 Solar cell with high photoelectric conversion efficiency and method for manufacturing solar cell with high photoelectric conversion efficiency
A method for manufacturing a solar cell, including the steps of: forming unevenness on both of main surfaces of a semiconductor substrate of a first conductivity type; forming a base layer on a first main surface of the semiconductor substrate; forming a diffusion mask on the base layer; removing the diffusion mask in a pattern; forming an emitter layer on the portion of the first main surface where the diffusion mask have been removed; removing the remaining diffusion mask; forming a dielectric film on the first main surface; forming a base electrode on the base layer; and forming an emitter electrode on the emitter layer. This provides a method for manufacturing a solar cell that can bring high photoelectric conversion efficiency while decreasing the number of steps.
US11271119B2 LIFT printing of conductive traces onto a semiconductor substrate
A method for metallization includes providing a transparent donor substrate (34) having deposited thereon a donor film (36) including a metal with a thickness less than 2 μm. The donor substrate is positioned in proximity to an acceptor substrate (22) including a semiconductor material with the donor film facing toward the acceptor substrate and with a gap of at least 0.1 mm between the donor film and the acceptor substrate. A train of laser pulses, having a pulse duration less than 2 ns, is directed to impinge on the donor substrate so as to cause droplets (44) of the metal to be ejected from the donor layer and land on the acceptor substrate, thereby forming a circuit trace (25) in ohmic contact with the semiconductor material.
