Abstract: A device for providing a 1D line of an image is disclosed. The device includes a wavelength-tunable light source for providing image light having the angular distribution encoded in optical spectrum. The device further includes a thin slab waveguide having an out-coupler in form of a diffraction grating for out-coupling the image light at an angle dependent on wavelength. The image may be formed by scanning a collimated beam propagating in the slab waveguide when using tunable monochromatic light sources, or by forming the 1D singular distribution of brightness at a same time when using a tunable-spectrum light sources. The device may be used in a near-eye display for forming a 2D image in angular domain.

Abstract: A wireless device receives a first downlink control information (DCI) scheduling transport blocks (TBs) via physical downlink shared channels (PDSCHs) in slots, wherein the first DCI comprises a hybrid automatic repeat request (HARQ) feedback timing indicator indicating an inapplicable value and a first PDSCH group index for the PDSCHs. After receiving the TBs in the slots, the wireless device receives a second DCI indicating a second PDSCH group index; and transmits HARQ feedback information for the TBs in response to: the HARQ feedback timing indicator, of the first DCI, indicating the inapplicable value and the first PDSCH group index of the first DCI being equal to the second PDSCH group index of the second DCI.

Abstract: An asynchronous approach to implementing a quantum algorithm can reduce dead time of a quantum information processing unit (QIPU). Multiple parameter sets are determined for a quantum program by a controller and the QIPU is instructed to execute the quantum program for the parameter sets. Results from each program execution are returned to the controller. After one or more results are received, the controller determines an updated parameter set while the QIPU continues executing the quantum program for the remaining parameter sets. The QIPU is instructed to execute the quantum program for the updated parameter set (e.g., immediately, after a current program execution, or after the remaining parameter sets are processed). This asynchronous approach can result in the QIPU having little or no dead time, and thus can make more efficient use of the QIPU.

Abstract: Metadata for one or more highlights of a video stream may be extracted from one or more card images embedded in the video stream. The highlights may be segments of the video stream, such as a broadcast of a sporting event, that are of particular interest. According to one method, video frames of the video stream are stored. One or more information cards embedded in a decoded video frame may be detected by analyzing one or more predetermined video frame regions. Image segmentation, edge detection, and/or closed contour identification may then be performed on identified video frame region(s). Further processing may include obtaining a minimum rectangular perimeter area enclosing all remaining segments, which may then be further processed to determine precise boundaries of information card(s). The card image(s) may be analyzed to obtain metadata, which may be stored in association with at least one of the video frames.

The lid may further include a guide channel configured to receive the slider, and the channel may limit the lateral movement of the slider. The guide channel may further include a pair of air vents. The slider may be configured to slide along the lid, from a closed position where the slider covers the opening and to an opened position in which the slider uncovers the opening such that the contents of the container may be released. The slider may be configured to lock into place in both the closed position and the opened position.

Abstract: A method for improving efficiency of routing edge compute traffic from a user equipment (UE) to an edge compute server at a far edge of a cellular network includes provisioning a near edge control unit (CU) and a near edge user plane function (UPF) at a near edge of the cellular network. The method also includes provisioning a far edge CU, a far edge UPF, and an edge compute workload at the far edge.

Abstract: Elliptic Curve Cryptography (ECC) can provide security against quantum computers that could feasibly determine private keys from public keys. A server communicating with a device can store and use PKI keys comprising server private key ss, device public key Sd, and device ephemeral public key Ed. The device can store and use the corresponding PKI keys, such as server public key Ss. The key use can support all of (i) mutual authentication, (ii) forward secrecy, and (iii) shared secret key exchange. The server and the device can conduct an ECDHE key exchange with the PKI keys to mutually derive a symmetric ciphering key K1. The device can encrypt a device public key PK.Device with K1 and send to the server as a first ciphertext. The server can encrypt a server public key PK.Network with at least K1 and send to the device as a second ciphertext.
