Abstract: A light projector for an augmented reality headset is disclosed. First and second optical arrangements receive light from a polarising beam splitter so that light is reflected, focused and directed back towards the polarising beam splitter from each optical arrangement. The first and second optical arrangements comprise first and second mirrors and first and second quarter-wave plates. The polarising beam splitter receives and combines light from the first and second optical arrangements so that the combined light, which is unpolarised, is provided to an exit pupil. The first and second optical arrangements are angled relative to one another so that the image from the first optical arrangement is aligned with the image from the second optical arrangement.

Abstract: A projector for generating a frame of an image is disclosed, comprising an array of elements arranged in a plane, each element comprising at least three LEDs which have different respective colours, and an array of collector structures, each configured to receive light from a single LED at any one time and reduce the angle over which the LED emits light. A projector unit is configured to receive the light from the array of collector structures and collimate the light such that a full colour frame is formed from combining a plurality of subframes formed through a spatial movement of the array of elements with respect to the array of collector structures such that each collector structure receives light from a different LED during each subframe, and/or a displacement of the light emitted from each LED such that the light from each LED illuminates multiple pixels of the frame.

Abstract: A system includes a functional unit having a processor and address management circuitry. The address management circuitry is to receive a request from the processor, where the request is associated with a boot process initialized at the processor. The address management circuitry is to determine a bit stored at the address management circuitry has a first value indicating to associate the request with a first node identifier associated with a memory region storing data associated with the boot process instead of a second node identifier associated with nodes storing physical locations associated with a memory address of the request. The address management circuitry can further transmit the request with the first node identifier to logic at a first node coupled to the memory region responsive to determining the bit has the first value.

Abstract: A golf swing training device attachable to a golfer's wrist. A rigid hand stop prevents the golfer's hand from bending beyond a pre-established distance or angle during a golf backswing. The rigid hand stop is configured and positioned to not interfere with, or restrict, the golfer's address of the golf ball or the early part of the backswing. The rigid hand stop allows desired movement of, and prevents undesired movement of, the golfer's rear hand (i.e., right hand for right-handed golfers and left hand for left-handed golfers) as the golfer moves from ball address through the backswing to the downswing to the impact position and finally the follow through. A pliable ball member may be integral with, or removably attachable to, the golf swing training device to maintain wrists of the user in a spaced relationship through a golf swing.

Abstract: The installation of a pool fence, specifically a pool gate, requires the drilling of installation holes on the ground near the pool. If the distance between the installation holes for the pool gate does not equal the distance between the pegs coupled to the pool gate, a peg shifter may be used that has an adjustable peg that can shift to change the location of the peg to make equal the two aforementioned distances when the peg shifter is coupled to the pool gate. The adjustability of the location of the peg when coupled to the pool gate may be accomplished by restructuring the body of the peg shifter to off-center the peg. Such restructuring of the body of the peg shifter may be done by removing a shim attached to one side of the peg shifter to the opposite side.

Abstract: Architectures and techniques are described that can implement or rely upon multiple different sources of truth (SOT) repositories, each of which can comprise authoritative versions of codebase, configurations, or other artifacts for different environments of an orchestration platform. For example, a first SOT repository can be utilized for a staging environment of the orchestration platform, while a second SOT repository, which differs from the first SOT repository, can be utilized for a production environment of the orchestration platform. Moreover, the disclosed techniques can tie a formal review process to a deployment process for a software development project, e.g., by enforcing certain deployment constraints.

Abstract: A connector apparatus includes a housing and a locking mechanism. The locking mechanism includes a rotatable disc that cooperates with the housing to selectively secure a connector therewith. The locking mechanism also includes a first pawl and a second pawl configured to engage with the disc and at least one lock lever configured to engage with the disc. A first connector is secured to the housing via the disc engaging the pawls and the lock lever thereby rotationally locking the disc. A second connector actuates the pawls to disengage the disc and the lock lever is manually actuated to disengage the disc so that the first connector can be released while simultaneously securing the second connector to the housing.

Abstract: Disclosed herein are system, method, and computer program product embodiments for performing in-flight transformations of data streams. Complex event processing (CEP) operating on event records from various data streams can operate by storing the streamed event record data in a database, and then querying the data to perform a data transformation. However, in order to improve the performance of the data transformations and streamline CEP, a serverless architecture is introduced that can perform data transformations directly on streams, using attributes of the streamed record data defined in a schema. The resulting transformed data can then be provided by the serverless architecture to the CEP for direct access of the data most needed by the CEP.

Abstract: A data storage device can be symmetrically designed for multiple-orientation connection to a storage appliance. An electromagnetic locking mechanism can secure the data storage device in a connected state while data is being transferred to/from the data storage device. The electromagnetic locking mechanism can respond to changes in the state of data transfer to/from the data storage device. To facilitate increased bandwidth and capacity, the data storage device is optimally designed for increased thermal transfer from the device's memory to a finned housing comprising a material of substantial thermal mass.
