摘要： The present invention provides improved optical switches in which no mechanical movement is required to direct optical pathways between plural fiber ports and light transmission is bi-directional. Advantageously, the inventive switches permit bi-directional light transmission. The inventive switches also incorporate light bending devices to allow two fibers to be coupled to the light beams using a single lens for compactness. In the inventive switch, an optical signal is spatially split into two polarized beams by a birefringent element, which passes through a polarization rotation device that comprises waveplates, walk-off elements, and an electrically controllable polarization rotator, and recombine into an output fiber, achieving polarization independent operation. The switches of the present invention rely on electro-magnetically or electro-optically switching the beam polarizations from one state to another to rapidly direct the light path.

摘要： A virtual interface application presented in augmented reality (AR) is described for controlling Internet of Things (IoT) products. The virtual interface application enables a user of a portable electronic device to activate a virtual control interface overlay on a display, receive a selection from the user using her hands or feet, and send a control signal to a nearby IoT product which executes an action in accordance with the selection. The virtual control interface is presented on the display as a virtual object in an AR environment. The virtual interface application includes a foot tracking tool for detecting an intersection between the foot location (in the physical environment) and the virtual surface position (in the AR environment). When an intersection is detected, the virtual interface application sends a control signal with instructions to the IoT product.

摘要： Described are virtual AR interfaces for generating a virtual rotational interface for the purpose of controlling connected IoT devices using the inertial measurement unit (IMU) of a portable electronic device. The IMU control application enables a user of a portable electronic device to activate a virtual rotational interface overlay on a display and adjust a feature of a connected IoT product by rotating a portable electronic device. The device IMU moves a slider on the virtual rotational interface. The IMU control application sends a control signal to the IoT product which executes an action in accordance with the slider position. The virtual rotational interface is presented on the display as a virtual object in an AR environment. The IMU control application detects the device orientation (in the physical environment) and in response presents a corresponding slider element on the virtual rotational interface (in the AR environment).

摘要： A video processing device receives video data and transmits the video to a display device at a new bit rate that is dynamically adjusted based on variable conditions. The new bit rate is adjusted, at least, by scaling the video and/or a residual image and may be adjusted utilizing compression functions, compression parameters, scale factor, frame rate, color space, and chroma sub-sampling. The display receives video at the adjusted new bit rate and decompresses the video in accordance with corresponding adjustments in the video processing device. Bit rate determination is based on variable operating conditions, display information, image quality, BER, packet error, SNR, desired level of compression, energy consumption, link congestion and display capabilities. Video may be scaled prior to compression. The video may comprise a frame and/or a slice. DPCM, H.264, AVC, transform compression and scaling may be utilized. The display may utilize intra-frame spatial prediction.

摘要： Methods are provided for using a dewaxing catalyst formed using at least two structure directing agents for production of a lubricant base stock. For example, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic production of lubricant base stocks. Additionally or alternately, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can provide improved aromatic saturation during processing of a feed for lubricant base stock production.
