Abstract: An asymmetric key cryptographic system is used to generate a cryptographic certificate for authenticating a memory module. This certificate is generated based on information, readable by the authenticator (e.g., host system), from at least one device on the memory module that is not read in order to obtain the certificate. For example, the certificate for authenticating a module may be stored in the nonvolatile memory of a serial presence detect device. The certificate itself, however, is based at least in part on information read from at least one other device on the memory module. Examples of this other device include a registering clock driver, DRAM device(s), and/or data buffer device(s). In an embodiment, the information read from a device (e.g., DRAM) may be based on one or more device fingerprint(s) derived from physical variations that occur naturally, and inevitably, during integrated circuit manufacturing.

Abstract: An imaging system, optionally an intra-oral camera, includes a blue light source and a barrier filter over a camera sensor. Optionally, the imaging system can also take white light images. Optionally, the system includes positively charged nanoparticles with fluorescein. The fluorescent nanoparticles can be identified on an image of a tooth by machine vision or machine learning algorithms on a pixel level basis. Either white light or fluorescent images can be used, with machine learning or artificial intelligence algorithms, to score the lesions. However, the white light image is not useful for determining whether lesions, particularly ICDAS 0-2 lesions, are active or inactive. A fluorescent image, with the fluorescent nanoparticles, can be used to detect and score active lesions. Optionally using a white light image and a fluorescent image together allows for all lesions, active and inactive, to be located and scored, and for their activity to be determined.

Abstract: The present technology includes systems and methods for invasively adjusting implantable devices for selectively controlling fluid flow between a first body region and a second body region of a patient. For example, in many of the embodiments described herein, a catheter can be used to mechanically and/or electrically engage an implanted medical device. Once the catheter engages the medical device, the catheter can (i) increase a dimension associated with the medical device, such as through mechanical expansion forces, and/or (ii) decrease a dimension associated with the medical device, such as by heating a shape memory component of the medical device above a phase transition temperature.

When simulating the risk model, systems and methods may adjust sampled values quantitative assumption object when a child qualitative assumption object is enabled.

Abstract: A syringe stabilizing apparatus has a base and a syringe support. The syringe support is vertically disposed above the base, elevating a fluid-filled portion of an infusion set vertically above the base and orienting a delivery end of the fluid-filled portion upwardly relative to a horizontal plane to take advantage of a gravitational effect on a fluid during delivery of the fluid from the fluid-filled portion to a patient. The syringe support comprises a first retainer and a selectively actuated tube clamp. The first retainer has an opening in which a rigid portion of the infusion set is received and retained therein without further user intervention. The selectively actuated tube clamp is operatively aligned with the first retainer. A flexible tube extending from the rigid portion of the infusion set extends through the selectively actuated tube clamp.

Abstract: Technologies for a field effect transistor (FET) with a ferroelectric gate dielectric are disclosed. In an illustrative embodiment, a perovskite stack is grown on a buffer layer as part of manufacturing a transistor. The perovskite stack includes one or more doped semiconductor layers alternating with other lattice-matched layers. Growing the doped semiconductor layers on lattice-matched layers can improve the quality of the doped semiconductor layers. The lattice-matched layers can be etched away, leaving the doped semiconductor layers as fins for a ribbon FET. A ferroelectric layer can be conformally grown on the fins, creating a high-quality ferroelectric layer above and below the fins. A gate can then be grown on the ferroelectric layer.

Abstract: The present disclosure relates to systems, methods, and computer readable media for identifying and responding to a panic condition on a storage system on a computing node. For example, systems disclosed herein may include establishing recovery instructions between a host system and a storage system in responding to a future instance of a panic condition. The storage system may provide an indication of a self-detected panic condition in a variety of ways. In response to identifying the panic condition, the host system may perform one or more recovery actions in accordance with recovery instructions accessible to the host system. This may include performing resets of specific components and reinitializing communication between the host system and storage system in less invasive ways than slower and more expensive conventional approaches for responding to panic conditions on computing nodes.

Abstract: Technologies for a field effect transistor (FET) with a ferroelectric gate dielectric are disclosed. In an illustrative embodiment, a perovskite stack is grown on a buffer layer as part of manufacturing a transistor. The perovskite stack includes one or more doped semiconductor layers alternating with other lattice-matched layers, such as undoped semiconductor layers. Growing the doped semiconductor layers on lattice-matched layers can improve the quality of the doped semiconductor layers. The lattice-matched layers can be preferentially etched away, leaving the doped semiconductor layers as fins for a ribbon FET. In another embodiment, an interlayer can be deposited on top of a semiconductor layer, and a ferroelectric layer can be deposited on the interlayer. The interlayer can bridge a gap in lattice parameters between the semiconductor layer and the ferroelectric layer.

In the illustrative embodiment, a transistor has a thin layer of scandium aluminum nitride (ScxAl1-xN) ferroelectric gate dielectric. The channel of the transistor may be, e.g., gallium nitride or molybdenum disulfide.

In another embodiment, the ferroelectric polarization of a gate dielectric of a transistor changes when the voltage is past a positive threshold value or a negative threshold value. Such a transistor can be used as a one-transistor memory cell.

Abstract: An elliptic curve random number generator avoids escrow keys by choosing a point Q on the elliptic curve as verifiably random. An arbitrary string is chosen and a hash of that string computed. The hash is then converted to a field element of the desired field, the field element regarded as the x-coordinate of a point Q on the elliptic curve and the x-coordinate is tested for validity on the desired elliptic curve. If valid, the x-coordinate is decompressed to the point Q, wherein the choice of which is the two points is also derived from the hash value. Intentional use of escrow keys can provide for back up functionality. The relationship between P and Q is used as an escrow key and stored by for a security domain. The administrator logs the output of the generator to reconstruct the random number with the escrow key.
