Abstract: Methods and apparatus, including computer program products, are provided for increasing uplink beamforming gain. In one aspect there is provided a method of identifying user equipment which makes use of the proposed new beam-sweeping random access channel procedure that enables the base station to identify the best uplink transmit beam rather than the first beam that the base station managed to detect. Related apparatus, systems, methods, and articles are also described.

Abstract: A vehicle control system may include one or more processors and a memory comprising instructions executable by the processors, the processors operable to execute the instructions to perform operations comprising detecting a signal to activate vehicle lamps in a delivery lighting pattern. In some embodiments, the processors may be further operable to execute the instructions to perform operations including activating the vehicle lamps in the delivery lighting pattern, wherein a flashing frequency of the delivery lighting pattern differs from a flashing frequency of a hazard lighting pattern.

Abstract: Particular embodiments may provide for a method of providing illumination for a vehicle. A user input related to controlling a headlamp assembly for a vehicle may be received. The headlamp assembly may comprise a laser-based lamp positioned to provide high-beam illumination, including a plurality of beam subfields, and a light sensor configured to capture images of objects illuminated by the headlamp assembly. Instructions to activate the headlamp assembly may be sent. Images of a scene illuminated by the headlamp assembly may be captured. An object of interest in the images of the scene may be detected. The detected objects may be identified as a traveling vehicle moving along a path in a beam field of the lamp. Instructions to dim light emitted by the laser-based lamp within at least one subfield of the beam field may be sent. The subfield may correspond to a location of the traveling vehicle.

Abstract: Particular embodiments may provide for a method of providing illumination for a vehicle. A user input related to controlling a headlamp assembly for a vehicle may be received. The headlamp assembly may comprise a laser-based lamp configured to provide broad-spectrum, incoherent white light for high-beam illumination, a laser-based infrared lamp, and a light sensor configured to capture images of objects illuminated by the headlamp assembly. Instructions to activate the headlamp assembly may be sent. Images of a scene illuminated by the headlamp assembly may be captured by the light sensor. An object of interest in the images of the scene may be detected. Generation of an alert to a driver of the vehicle regarding the one or more objects of interest may be facilitated.

Abstract: An assembly is provided for a turbine engine. This turbine engine assembly includes an impeller rotor, a seal land and a lip seal. The impeller rotor is configured to rotate about a rotational axis. The impeller rotor is configured from or otherwise includes impeller rotor material. The seal land extends axially along and circumferentially about the rotational axis. The seal land is mechanically attached to and rotatable with the impeller rotor. The seal land is configured from or otherwise includes seal land material that is different than the impeller rotor material. The lip seal radially engages the seal land.

Abstract: An assembly is provided for a turbine engine. This assembly includes a static structure and an impeller rotor housed within the static structure. The impeller rotor includes a vane structure and a shroud. The vane structure includes a first sidewall, a second sidewall and a plurality of vanes arranged circumferentially about a rotational axis. The vanes include a first vane. The first vane includes a first portion, a second portion and a third portion. The first portion is axially between the first sidewall and the second sidewall. The second portion is radially between the first sidewall and the shroud. The third portion is radially between the second sidewall and the shroud. The shroud circumscribes the vane structure. A gap is formed by and extends between the shroud and the static structure. A dimension of the gap changes as the gap extends along the shroud.

Abstract: The present disclosure relates to compositions including a shell surrounding an interior compartment, wherein said interior compartment comprises one or more reagent and wherein said shell releases said interior compartment when said shell is exposed to a first release condition, wherein said interior compartment releases said one or more reagent when said interior compartment is exposed to a second release condition, and wherein said first release condition is different from said second release condition. Also disclosed are compositions including a dissolvable first shell, and a dissolvable second shell, the second shell comprising one or more reagent. Also disclosed are methods for controlling release of one or more reagent using the compositions described herein. The present disclosure further relates to cartridges that include a reagent reservoir including the compositions described herein.

Abstract: The present invention discloses fiducial marker systems or tag systems and methods to detect and decode a tag. The tag comprises a plurality of cells arranged in a grid pattern. The plurality of cells forms a square or rectangular shape. Each cell is in square or rectangular shape and has either black, white, or gray grayscale. Any two cells that share a common borderline should have different grayscales; and the four corner cells of the tag are all in black.

Abstract: A system and method are disclosed for quickly and easily browsing to points of interest within a recorded video. In examples, the present system works in tandem with a segment list which includes a list of different video sequences of a stored video of an event. One typical example of a segment list is a play-by-play (PBP) which is prepared contemporaneously with a sporting event. Segments from a segment list may be associated with, or indexed to, corresponding sequences from the stored video. Thereafter, a user interface allows a user to interactively watch or browse the event by jumping to a desired point in the video for playback by selecting its associated segment from the user interface.
