  • Publication number: 20240381053
    Abstract: An ultra-wideband (UWB) ranging method comprises determining, by a first device, that the first device is within proximity of a second device. Responsive to the determination, the first device negotiates a value to use as a UWB session key for securing UWB communications with the second device. The negotiation occurs via a communication protocol different from a UWB communication protocol. The first device controls a UWB subsystem therein to encrypt information communicated via the UWB subsystem based on the negotiated value of the UWB session key instead of a default value for the UWB session key that is specified in the UWB communication protocol. The information facilitates determining the distance between the first device and the second device.

  • Patent number: 11471015
    Abstract: A surface cleaning apparatus is described including a housing supporting a suction source, a dirt collection container, and a cyclonic separation device for separating dirt from the airflow passing through the apparatus. The apparatus further includes a ducting member having an inlet in communication with an outlet from the cyclonic separation device and an outlet in communication with a passage leading to the suction source. The ducting member is removably connected to the housing or the dirt collection container and is rotatably moveable between locked and unlocked positions, and rotational movement of the ducting member from its unlocked position to its locked position aligns the outlet of the ducting member with the passage leading to the suction source.

  • Patent number: 11284761
    Abstract: A cyclonic separator device for removing dust or debris from dirt-laden air, the device having a separating chamber, an inlet, an outlet, and a shroud that is connected to the separating chamber at one end, and provides a plurality of openings for the passage of air to the outlet. The device further includes a dirt collection chamber in communication with the separating chamber. The separating chamber includes an airflow directing formation which is connected to an inner surface of a generally cylindrical portion and which extends inwardly towards a central axis of the generally cylindrical portion. The airflow directing formation provides a surface which follows a substantially helical path that extends away from the inlet as it extends circumferentially around the inner surface of the generally cylindrical portion.

  • Patent number: 10992482
    Abstract: Methods, systems, and apparatus, including computer-readable media, for verified boot and key rotation. In some implementations, a device extracts a public key from a secure data storage area of the device. The device extracts a first certificate for an intermediate key and a second certificate for a signing key, the first certificate and the second certificate being extracted from a system image. The device verifies a signature of the first certificate using the public key. After verifying the signature of the first certificate, the device verifies the second certificate using a public key in the first certificate. In response to verifying the second certificate, the device loads the system image during a boot process of the device.

  • Publication number: 20180140150
    Abstract: A surface cleaning apparatus having a dirt collection container which is removable from a remainder of the apparatus. The dirt collection container is held in a stored position relative the remainder of the apparatus by a holding device. The holding device includes a first co-operating member provided in, provided on or connected to the dirt collection container, a second co-operating member provided in, provided on or connected to the remainder of the apparatus. Movement of the dirt collection container towards its stored position engages the first and second co-operating members with each other and effects either rotation of the first co-operating member relative to the dirt collection container and/or rotation of the second co-operating member relative to the remainder of the apparatus.
