  • Patent number: 11622232
    Abstract: A target user equipment (UE), which may be a vehicle or UE carried by a pedestrian, may receive sequentially broadcast ranging signals from a set of ranging source entities (SEs), which may be road side units or other vehicles. The target UE further receives location information separately broadcast by each SEs. The location information, for example, may include the position for the SE, the time of transmission of the ranging signals transmitted by the SE and/or a sequence identifier for the SE. The target UE may determine ranges to the SEs using time of arrival measurements for the ranging signals and the time of transmissions of the ranging signals or the sequence identifier received in the location information. The position of the target UE may be determined using the determined ranges to the SEs and the positions of the SEs received in the location information.

  • Patent number: 11619981
    Abstract: A drive (e.g., hard drive) carrier can have a frame with a door that can open to permit installation of the drive and can snap shut to secure the drive within the drive carrier. The drive carrier can include a connector lock, which can take the form of a pair of pins extending from the frame and capable of engaging corresponding retention holes of a connector of a cable. The connector lock can help align the cable's connector with the drive's connector, as well as releasably lock the cable's connector in place when operatively connected to the drive. Damping couplings can couple the carrier frame to a computer chassis. The damping couplings and the flexibility of the cable vibrationally isolate the drive from the chassis, while the connector lock ensures the cable's connector does not unintentionally disconnect from the drive.
