  • Patent number: 11843685
    Abstract: A vehicular communication controller includes a microcontroller (MCU) located within a vehicle to publish a newly defined protocol data unit (PDU) including a header and a payload portion to a destination device. The destination device may utilize a first protocol or a second protocol. If the destination device utilizes the first protocol that includes an automotive/embedded communication protocol then the MCU serializes the payload portion of the PDU and binds the PDU to the first protocol. The destination device may then receive the PDU using the first protocol, deserialize the payload portion, and remove the header leaving the payload portion unchanged and recreate, based on the deserialized payload portion, the PDU.

  • Patent number: 11842310
    Abstract: A risk assessment system is provided and includes a transceiver, an output device, and activity, localization, tracking, and risk assessment modules. The activity module: receives signals from sensors or electrical devices of a supporting structure; and tracks activities in or within a set distance of the supporting structure to generate an activity history log. The localization module relates the activities to aspects of the supporting structure and generates corresponding localization data. The transceiver receives a notification key identifying a network device used by a user exposed to a contaminant. The tracking module, in response to the notification key, tracks contamination states of the aspects of the supporting structure contacted directly or indirectly by the user. The risk assessment module determines and reports an exposure risk level of an occupant of the supporting structure based on the contamination states, the localization data and the activity history log.

  • Patent number: 11841078
    Abstract: A transmission hydraulic control system includes a manual valve, a default valve, and a clutch prime valve. The manual valve allows fluid flow from a pressurized line to a drive line when the manual valve is open (when a transmission is in drive or reverse). The manual valve prevents fluid flow from the pressurized line to the drive line when the manual valve is closed (when the transmission is in neutral or park). The clutch prime valve allows fluid to flow from the pressurized line to the drive line, and thereby bypass the manual valve, when the manual valve is closed and the clutch prime valve is open. The default valve allows fluid bypassing the manual valve to flow to prime a clutch of the transmission when the default valve is open. The clutch prime valve prevents fluid from bypassing the manual valve when the clutch prime valve is closed.
