  • Publication number: 20240169098
    Abstract: This document discloses aspects of secure chip-wide communication. In some aspects, a host of a system generates integrity metadata for a command payload issued to a destination over an interconnect of the system. The integrity metadata can be generated based on respective values of bits that form the command payload, such as plaintext data bits. The destination validates the integrity of the command payload based on the integrity metadata before consuming the command payload. In some cases, the destination stores the integrity metadata with data of the command payload, which may be returned to the host along the data when requested. By so doing, the host and destinations of the system can use the integrity metadata to implement secure-chip wide communication, which may prevent fault injection attacks on the command payloads or response data during transit or at temporal storage locations within the system.

  • Patent number: 11972033
    Abstract: An IC chip can provide silicon root of trust (RoT) functionality. In described implementations, the IC chip includes a processor, an alert handler, and multiple peripheral devices, which generate alert indications. The alert handler processes the alert indications, which have security implications. The alert handler includes multiple alert receiver modules to communicate with the multiple peripheral devices. The alert handler also includes a controller, multiple accumulation units, multiple escalation timers, and multiple escalation sender modules. These components can be organized into a hierarchy of increasing escalation severity. In operation, the controller classifies an alert and flexibly implements an adaptable alert handler path that is established through the escalation components responsive to the classification and based on a source of the alert. A path can conclude with an escalation sender module commanding an escalation handler to implement a security countermeasure.

  • Publication number: 20240132330
    Abstract: Motor control architecture including a travel, a hoist, and a controller is disclosed. The travel disposed on a main rail having an auxiliary-encoder includes a master-driver and a slave-driver for driving two motors. Each motor has a main-encoder. The hoist drives a rope and calculates a rope length continuously. The controller calculates an anti-sway position command based on the rope-length and a position command. The two drivers perform a full closed-loop computation based on a feedback of one main-encoder, a feedback of the auxiliary-encoder, and the anti-sway position command. Wherein, the master-driver controls one motor based on a speed command generated by the full closed-loop computation and the slave-driver follows the speed command and a torque command of the master-driver to drive another motor; or the two drivers compensate the torque command based on an error value between the feedback of one main-encoder and the feedback of the auxiliary-encoder.

  • Publication number: 20240126886
    Abstract: This document describes techniques and systems for providing trusted computing for digital devices. The techniques and systems may use cryptographic algorithms to provide trusted computing and processing. By doing so, the techniques help ensure authentic computation and prevent nefarious acts. For example, a method is described that receives a signature associated with a designee and validates the signature. The signature may be associated with a designee of a host computing device, and the signature may be generated according to firmware associated with an integrated circuit of the host computing device and a first private key of a first asymmetric key pair. Signature validation may be based on a second asymmetric key pair having a second private key and a second public key, the second private key stored in write-once memory of the host computing device.

  • Patent number: 11963213
    Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved interference tracking over time. A BS may transmit information to a UE that allows the UE to quantize channel measurements into interference states. The UE may transmit an interference change report as triggered by an event, such as an interference metric exceeding a threshold after quantizing into the interference states. This enables the system to capture and respond to abrupt changes. Further, the interference change report may include historic interference information. The UE may include statistics based on the historic interference information. The UE may further be triggered to transmit an interference change report in response to a BS requesting it, or in response to a configured period of time elapsing. The UE may further include MCS information predicted for one or more future time periods based on historic information, which the BS may use in scheduling.

  • Patent number: 11962543
    Abstract: Wireless communications systems and methods related to full-duplex cooperative communication by a first device tethered with a second device communicating with a third device. With the tether, one device between the first device and the second device is designated or selected as a transmitter, and the other device as a receiver. In full-duplex operation, the transmitter may transmit outgoing data concurrent to the receiver receiving incoming data. In an example, one of the first and second devices may have a modem that is used to control the full-duplex communication. The modem controls both transmission and reception. In another example, both devices may have a modem. Each modem may assume responsibility for part of the full-duplex communication by performing some processing before either shipping received data, or transmitting outgoing data. The amount of processing may be split at a link layer. Interference cancellation may mitigate interference from full-duplex operation.

  • Patent number: 11958938
    Abstract: Provided is a curative part usable in a two-part curable composition. The curative part includes a liquid amine; a heterogeneous dispersant; and core-shell rubber particles having an elastomeric core and a (meth)acrylic shell. The core-shell rubber particles and the heterogeneous dispersant can be collectively shear-dispersed in the liquid amine such that the core-shell rubber particles are substantially non-aggregated and the curative part is phase-stable over a period of at least 3 months at ambient temperature. Advantageously, large amounts of core-shell rubber particles can thus be incorporated into a cured resin matrix, which can afford significantly enhanced impact performance.

  • Publication number: 20240080690
    Abstract: This disclosure provides methods, devices and systems for link adaptation in wireless communications. Some implementations more specifically relate to transmitter-based modulation and coding scheme (MCS) selection. A transmitting device transmits a test packet, over a wireless channel, to a receiving device. The receiving device generates one or more signal-to-interference-plus-noise ratio (SINR) estimates for the wireless channel based on the received sounding packet. In some aspects, each SINR estimate may be associated with a particular modulation order. In some other aspects, each SINR estimate may be generated based on a transmitter configuration or a receiver type to be used for subsequent communications between the transmitting device and the receiving device. The receiving device transmits feedback, including the SINR estimates, to the transmitting device.

  • Patent number: 11924812
    Abstract: This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.
