Abstract: A method and a device is provided for utilizing unused valid (V) bits residing on a previous command to transmit additional activate information to a memory device. Additional activate information may be transmitted to the memory device without increasing the tRCD time, or increasing the command/address (CA) bus pins, or adding additional circuit area, thereby reducing the impact on the performance of the memory device.

Abstract: Medical devices configured for in vivo assays of one or more analytes can sometimes be problematic if left inserted in a tissue, such as skin, for an extended time. Certain medical device surface profiles may aid in alleviating this issue. Accordingly, medical devices may comprise a base surface having a tissue-facing surface profile defined thereon, and a sensor extending through the base surface and at least a portion of the tissue-facing surface profile. The tissue-facing surface profile deviates from the base surface, and the tissue-facing surface profile is also configured to undergo a change in shape, hardness, or a combination thereof after contacting a tissue for a length of time. A dynamic material may be present in at least a portion of the tissue-facing surface profile.

Abstract: A method for dynamic immutable security personalization for enterprise products. Specifically, the disclosed method describes how a computer processor (e.g., baseboard management controller) of an enterprise product can personalize security requirements in trusted facilities, along the supply chain route of the enterprise product, so that trusted assumptions concerning the enterprise product can be made. Further, through dynamic immutable security personalization, these trusted assumptions are allowed to change over time (e.g., from being less restrictive to more restrictive) as changing enterprise product configuration states are captured while the enterprise product traverses the supply chain route.

Abstract: An innovative system and method is implemented to facilitate a blockchain based labor arbitrage. The system uses a processor to manage labor arbitrage between business operator devices and laborer devices. The method starts with a description for a job request received from a business operator device. After distributing the job description, the method receives proposals from the laborer devices. Then method matches a primary laborer device to the job description and generates a smart contract in the blockchain between the business operator device and the primary laborer device. Upon job completion, the method verifies that all job requirements plus quality standards are satisfactorily met and signatures of both the business operator device and the primary laborer device are validated, the method transmits a compensation of a predetermined type and amount of cryptographic token to the primary laborer device. With any disputes, the method further provides an arbitration process.

Upon a transfer of control or ownership of the IHS, replaceable hardware components that are coupled to the IHS are detected, and the replaceable hardware certificate is utilized to validate that the identified replaceable hardware components detected as coupled to the IHS are the same replaceable hardware components coupled to the IHS during the factory provisioning. A security processor of the IHS may support boot code operations for generating additional replaceable hardware certificates that can be used to validate the integrity of any changes the replaceable hardware of the IHS, such as upon its next power cycle.

Upon a transfer of control or ownership of the IHS, a pre-boot configuration of the IHS is identified and the configuration certificate is utilized to validate that the identified pre-boot configuration is the same as the pre-boot configuration of the IHS resulting from the factory provisioning. A security processor of the IHS may support boot code operations for generating additional configuration certificates that can be used to validate the integrity of any changes the IHS configuration, such as upon its next power cycle.

Abstract: During factory provisioning of an Information Handling System (IHS), a key injection authorization certificate is stored that authorizes key injection by a renter of the IHS. An IHS owner retains capabilities for specifying the use of boot code of successive renters of the IHS. Upon a transfer of control or ownership of the IHS, a key injection request certificate provided by the renter is validated and use of the key injection request certificate is authorized for transferring cryptographic credentials to the IHS. The key injection authorization certificate specifies an identity of the IHS that is authorized for key injection by the renter and the key injection request certificate specifies an identity of the IHS that is requested for key injection by the renter. Transfer of credentials is authorized when the two certificates are both valid and the identity of the IHS specified in the two certificates is the same.

The BMC includes executable instructions for monitoring a parameter of one or more of the hardware devices when a custom BMC firmware stack is executed on the BMC.

The instructions also control the BMC to perform one or more operations to remediate an excessive parameter when the parameter exceeds a specified threshold.

Abstract: The efficacy in the use of probiotics is compromised due to their lack of survivability in gastric conditions (pH 1.5-3), leading to a large reduction in viable probiotic cells. The present disclosure describes cellulose nanocrystals (CNCs) modified with ferulic acid (FA) and shellac (SH) to produce two types of new coating materials, which are environment friendly and harmless to humans. These coating materials were developed and utilized to formulate Pickering emulsions (W1/O/W2 and W/O) for probiotic encapsulation. Based on their pKa values, greater than pKa, carboxyl groups from the CNCFA and CNCSH based Pickering emulsions were deprotonated, inducing phase separation and allow yeast releasing. This system could be further investigated for functionalized food-based applications to deliver active substances, such as probiotics, at high pH. Such delivery systems can be applied to human, animal, and aquatic systems.

Abstract: Systems and methods provide validation of hardware components of an IHS (Information Handling System). An attestation certificate stored to the IHS specifies authenticated instructions for operation of a hardware component of the IHS. This attestation certificate is endorsed by a self-signed root attestation certificate. An identity certificate, also stored to the IHS, specifies an identity of the hardware component and is endorsed using an embedded keypair of the hardware component. The root attestation certificate is validated to ensure it corresponds to the hardware component specified in the identity certificate, where this validation confirms that a public key included in the identity certificate is identical to a public key included in the attestation certificate.

Abstract: In general, embodiments of the invention relate to implementing a secure boot process in information handling systems that supports both an external root of trust (eRoT) and an internal root of trust (RoT). Further, embodiments of the invention relate to binding a management controller to a specific chassis and, in the case where the eRoT is used, to an eRoT. When the management controller and the chassis are provisioned according to one or more embodiments of the invention, security checks may be performed by management controller executing an initial program loader (IPL) using the aforementioned bindings. If the bindings are not present or do not match, then the boot process halts and the user is unable to use the information handling system.
