  • Patent number: 11735685
    Abstract: A method for preparing a crystalline semiconductor layer in order for the layer to be provided with a specific lattice parameter involves a relaxation procedure that is applied for a first time to a first start donor substrate in order to obtain a second donor substrate. Using the second donor substrate as the start donor substrate, the relaxation procedure is repeated for a number of times that is sufficient for the lattice parameter of the relaxed layer to be provided with the specific lattice parameter. A set of substrates may be obtained by the method.

  • Patent number: 11733187
    Abstract: An electron beam additive manufacturing system includes an electron beam source, an x-ray detection sensor configured to generate a waveform corresponding to an amount of x-rays detected by the x-ray detection sensor, and an electronic control unit comprising a processor and a non-transitory computer-readable memory, the electronic control unit communicatively coupled to the electron beam source and the x-ray detection sensor. The electronic control unit is configured to cause the electron beam source to emit an electron beam such that the electron beam impinges a verification plate, receive the waveform generated by the x-ray detection sensor in response to the x-ray detection sensor capturing x-rays emitted from the impingement of the electron beam with the verification plate, and determine a melt performance of a surface material of the verification plate based on the waveform.

  • Patent number: 11734010
    Abstract: An execution unit circuit for use in a processor core provides efficient use of area and energy by reducing the per-entry storage requirement of a load-store unit issue queue. The execution unit circuit includes a recirculation queue that stores the effective address of the load and store operations and the values to be stored by the store operations. A queue control logic controls the recirculation queue and issue queue so that that after the effective address of a load or store operation has been computed, the effective address of the load operation or the store operation is written to the recirculation queue and the operation is removed from the issue queue, so that address operands and other values that were in the issue queue entry no longer require storage. When a load or store operation is rejected by the cache unit, it is subsequently reissued from the recirculation queue.

  • Patent number: 11734459
    Abstract: Physical Unclonable Functions, PUFs, are hardware devices designed to generate a number that is random (i.e., two identical PUFs should produce randomly different numbers from each other) and persistent (i.e., a PUF should consistently generate the same number over time). Over time, aspects of the PUF hardware may change or drift, which may ultimately cause the generated number to change, and therefore no longer be persistent. Failure to generate a persistent number may cause difficulties for other devices that rely on the persistence of the number generated by the PUF, for example as part of a cryptographic process. The present disclosure relates to monitoring over time the physical characteristics of the PUF that are used to generate its number, and thereby keep track of its reliability to generate a random number that is persistent.

  • Patent number: 11734697
    Abstract: Devices are often connected to a network to facilitate remote interactions with the device. However, such connections may be absent or disabled. However, by utilizing a second device, such as a mobile phone, a transaction may be initiated on a remote device and handed-off to the second device to obtain absent information and complete the transaction. Completion of the transaction may be due to absent data, such as a data that provides absent information or resolves conflicting information in the dataset. The device may communicate with the second device via radio frequency communications and/or other forms of communication (e.g., visually, audibly, etc.), such that information the absent information is obtained and the instructions executed to complete the transaction.

  • Patent number: 11734845
    Abstract: Systems and methods for extracting ground plane information directly from monocular images using self-supervised depth networks are disclosed. Self-supervised depth networks are used to generate a three-dimensional reconstruction of observed structures. From this reconstruction the system may generate surface normals. The surface normals can be calculated directly from depth maps in a way that is much less computationally expensive and accurate than surface normals extraction from standard LiDAR data. Surface normals facing substantially the same direction and facing upwards may be determined to reflect a ground plane.
