Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.

Abstract: Provided is a lens assembly driving module including a photographing lens assembly, a first driving mechanism and a second driving mechanism. The photographing lens assembly includes N lens elements and has an optical axis passing through the N lens elements. The first driving mechanism drives at least N/2 said lens elements to move along the optical axis of the photographing lens assembly. The second driving mechanism enables a relative distance along the optical axis of two adjacent ones of the N lens elements to vary. Therefore, any specific one of the lens elements is capable of being driven to optimize optical imaging resolution of various fields of view independently within a real shot at different object distances.

Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: An imaging lens module includes a casing, an imaging lens disposed to the casing, a lens carrier supporting the image lens, an elastic element connected to the lens carrier to provide the lens carrier with a translational degree of freedom along an optical axis, a frame connected to the elastic element such that the lens carrier is movable along the optical axis with respect to the frame, a variable through hole module coupled to the imaging lens and having a light passable hole with a variable aperture size, and a wiring assembly including a fixed wiring part at least partially located closer to the opening than the elastic element and a movable wiring part electrically connected to the fixed wiring part and the variable through hole module. The optical axis passes through lens elements of the imaging lens and the center of the variable through hole module.

Abstract: Systems and methods of secure firmware updates on remote vehicles are provided. The system receives a request from a vehicle for an update to vehicle firmware, and identifies a blockchain address for the vehicle. The system generates a session identifier and identifies a firmware update file. The system generates a digital signature based on a combination of the session identifier and a first hash value of the firmware update file. The system provides, for storage in a block at the blockchain address, the digital signature. The system transmits the session identifier to the vehicle. The system transfers the firmware update file to the vehicle. The vehicle verifies the firmware update file using the digital signature retrieved from the block at the blockchain address, a second hash value of the firmware update file received from the data processing system, and the session identifier received from the data processing system.

Abstract: Commanding vehicles via a vehicle-to-infrastructure communication network are provided. A roadside unit in a location on a vehicular travel path broadcasts timestamps. A vehicle having an onboard unit receives the timestamp, calibrates an internal clock, and transmits a status of the first vehicle to the first roadside computing unit. The roadside unit receives the status of the vehicle, and transmits, to a data processing system, data packets including the status and information associated with the location in the vehicular travel path. The data processing system inputs the status information and the information associated with the location into a deep learning engine to assign, based on an output from the deep learning engine, a label to the vehicle. The data processing system selects a vehicle command based on the label and transmits the vehicle command to the vehicle to execute an action for traversing the vehicular travel path.

Abstract: A system is provided that includes an artificial connection generator and a probe machine. The artificial connection generator is configured to establish one or more artificial connections with a server that at least partially hosts one or more services or applications for access by clients. The probe machine is configured to control a number of artificial connections with the server by the artificial connection generator. The probe machine also is configured to establish a probing connection with a server to determine a service time of the server that is indicative of a time period involved with execution by the server of one or more requests to the server. The probe machine is configured to derive a number of actual connections between the clients and the server based on changes in the service time of the server when the number of artificial connections with the server is varied.

Abstract: The present invention includes a housing, multiple conveyors, and a driving system. The conveyors are provided for a working object to be moved on the conveyors. The driving system has a horizontal moving portion and a vertical moving portion. As the horizontal moving portion moves from the second position toward the first position, when a first detector detects a rear edge of the working object, a controller is able to stop the horizontal moving portion and to set an actual pushing position. Then, it can reset that the horizontal only can move between the actual pushing position and the second position for shortening a moving time and a moving distance of the horizontal moving portion. So, this invention can shorten the horizontal moving time of the horizontal moving portion. It can shorten the vertical moving time. Plus, it can increase the total processing efficiency.

Abstract: Restoring retired transaction identifiers (TID) associated with Direct Memory Access (DMA) commands without waiting for all DMA traffic to terminate is disclosed. A scoreboard is used to track retired TIDs and selectively restore retired TIDs on the fly. DMA engines fetch a TID, and use it to tag every DMA request. If the request is completed, the TID can be recycled to be used to tag a subsequent request. However, if a request is not completed, the TID is retired. Retired TIDs can be restored without having to wait for DMA traffic to end. Any retired TID value may be mapped to a bit location inside a scoreboard. All processors in the system may have access to read and clear the scoreboard. Clearing the TID scoreboard may trigger a DMA engine to restore the TID mapped to that location, and the TID may be used again.
