Abstract: A method, system and computer readable medium for running a legacy application on a non-legacy device. Operating parameters of the non-legacy device when running the legacy application are set based on one or more pre-determined heuristics for adjustment of operating parameters of the newer system when running the legacy application on the non-legacy device from one or more performance metrics and other performance information.

Abstract: A method of and system for gate-level masking of secret data during a cryptographic process is described. A mask share is determined, wherein a first portion of the mask share includes a first number of zero-values and a second number of one-values, and a second portion of the mask share includes the first number of one-values and the second number of zero-values. Masked data values and the first portion of the mask share are input into a first portion of masked gate logic, and the masked data values and the second portion of the mask share are input into a second portion of the masked gate logic. A first output from the first portion of the masked gate logic and a second output from the second portion of the masked gate logic are identified, wherein either the first output or the second output is a zero-value.

Abstract: Systems and methods for protecting cryptographic keys stored in a non-volatile memory. An example method may comprise: storing a device root key in a non-volatile memory; storing a volatile key in a volatile memory; storing a masked cryptographic key in the non-volatile memory, wherein the masked cryptographic key is produced by combining a cryptographic key and the device root key; storing a masked device root key in the non-volatile memory, wherein the masked root key is produced by combining the device root key and the volatile key; and erasing the device root key from the non-volatile memory.

Abstract: Described are implementations directed to protecting secret data against adversarial attacks by obfuscating the secret data during storage and communication. Obfuscation techniques include, among other things, splitting secret data into a plurality of portions, performing rotation of secret data, splitting secret data into a plurality of shares, modifying shares of secret data in view of the values of the shares, and various other protection mechanisms.

Abstract: A spinal bone graft includes one or more cortical bone portions forming a first unit. The first unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms at least one first undercut. The bone graft also includes one or more cortical bone portions forming a second unit. The second unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms either at least one second undercut, or at least one connector. In the former, at least one connector is received in each of the first and second undercuts to interconnect the first and second units. In the latter, the at least one connector of the second unit is received in the first undercut of the first unit to interconnect the first unit and second unit.

Abstract: A graphics processing unit (GPU) includes one or more processor cores adapted to execute a software-implemented shader program, and one or more hardware-implemented ray tracing units (RTU) adapted to traverse an acceleration structure to calculate intersections of rays with bounding volumes and graphics primitives asynchronously with shader operation. The RTU implements traversal logic to traverse the acceleration structure including transformation of rays as needed to account for variations in coordinate space between levels, stack management, and other tasks to relieve burden on the shader, communicating intersections to the shader which then calculates whether the intersection hit a transparent or opaque portion of the object intersected. Thus, one or more processing cores within the GPU perform accelerated ray tracing by offloading aspects of processing to the RTU, which traverses the acceleration structure within which the 3D environment is represented.

Abstract: To identify and/or assess structural integrity of a composite material comprising fiduciary markers which attenuate x-rays to an extent greater than the rest of the material, a method is provided wherein x-ray 3D tomosynthesis images of the composite material are created using an array of x-ray emitters and a digital x-ray detector wherein the array of x-ray emitters and the digital x-ray detector are maintained in fixed relation to one another and to the composite material, the 3D tomosynthesis images being used to determine the relative location of at least some of the fiduciary markers with respect to one another; a database is provided for storing the relative location of at least some of the fiduciary markers with respect to one another, further x-ray 3D tomosynthesis images of the same, or a different, composite material may be checked against the data in the database to ascertain structural integrity and/or identity of the material.

Abstract: Performance of a legacy application may be characterized for subsequent adjustment of operating parameters when running the legacy application on a newer system. The legacy application is run on an older system and one or more key performance metrics that must be met when the legacy application is run on the newer system are determined along with other performance information useful for later adjustment of operating parameters of the newer system when running the legacy application on the newer system.

Abstract: A new device executing an application on a new central processing unit (CPU), determines whether the application is for a legacy device having a legacy CPU. When the new device determines that the application is for the legacy device, it executes the application on the new CPU with selected available resources of the new device restricted to approximate or match a processing behavior of the legacy CPU, e.g.

Abstract: The invention relates to interbody spacers constructed of allograft material. These allograft implants include a first plank of allograft that has a first fusion surface and a first mating surface, opposite the first fusion surface. A second plank of allograft includes second fusion surface and a second mating surface, opposite the second fusion surface. At least one interior plank of allograft has a third mating surface attached to the first mating surface, and a fourth mating surface opposite the third mating surface, attached to the second mating surface. At least one transverse connector interconnects the first, second, and interior planks of the allograft implants. The allograft implants may have at least one transverse passage, and transverse connectors may interconnect the planks through this passage. The ends of transverse connectors may be flush with the fusion surfaces, and those ends may comprise patterned projections.

Abstract: A random number generator selects addresses while a ‘scoreboard’ bank of registers (or bits) tracks which addresses have already been output (e.g., for storing or retrieval of a portion of the data.) When the scoreboard detects an address has already been output, a second address which has not been used yet is output rather than the randomly selected one. The second address may be selected from nearby addresses that have not already been output.

Abstract: Methods and apparatus for reducing the risk of neurological injury to a human fetus during labor and before are disclosed, which include the steps of: (1) identifying during labor the risk of neurological injury to a fetus by, conducting an analysis of fetal blood to determine at least a first base excess (BE) value for the fetus; (2) determining a multiple of the median for the BE value at the first period in time, wherein a risk of neurological injury to the fetus is indicated when the BE value is a predefined multiple of a median BE value; and (3) treating the fetus for which the risk of neurological injury is, by intervening in labor to reduce or eliminate the risk of neurological injury to the fetus through any conventional therapeutic measures.

Abstract: An x-ray imaging apparatus comprises a panel including individually energisable x-ray emitters, a detector and a processor, wherein the emitters and detector remain relatively stationary. The first set of x-ray emitters of the panel is energised to direct x-rays at the first object and surrounding area. The detector detects x-rays passing through the first object and surrounding area. Detected x-rays are processed to create a first x-ray image of the first object and surrounding area. A region of interest is selected from the first image which is smaller than the image of the first object and surrounding area. A second set of x-ray emitters of the panel is energised to direct x-rays at the region of interest. The detector detects x-rays passing through the region of interest. Detected x-rays are processed to create images of the region of interest to obtain tomosynthesis data showing structure of the region of interest.

Abstract: A roadside delineator device that includes a breakaway shear pin feature that allows the upper portion of the device to break away from the lower portion of the device during a vehicular accident. The upper and lower halves can be reconnected by replacing the broken shear pins. This allows the re-use of components and saves time and money by not having to install a completely new roadside delineator device.

Abstract: A data processing system includes a GPU and a switching instruction section. The GPU performs in a time-divided manner a process of generating a plurality of pieces of data corresponding to a plurality of applications executed in parallel. In the case where the GPU completes a process of generating one unit of data that is data corresponding to a first application and that is to be handed over to subsequent processing sections, the switching instruction section instructs the GPU to switch to a process of generating an image corresponding to a second application different from the first application.
