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.

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.

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.

Abstract: Provided is a process that controls an information display system (IDS) using a mobile computing device associated with a user by establishing a connection between the mobile computing device and the IDS, and transmits input events, such as touch events, on the mobile computing device to a server associated with the IDS, which further transmits the touch events to the IDS for performing one or more operations in the IDS responsive to the touch events.

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.

Abstract: A surface cleaning apparatus is described including a floor head, a housing supporting a suction source and a dirt collection container having an elongate axis (A). The device further includes an elongate member having an elongate axis (B), said elongate member connecting the floor head to the housing, said elongate member including a passage for carrying dirt-laden air from the floor head to the dirt collection container. The elongate axis (B) of the elongate member intersects or substantially intersects the elongate axis (A) of the dirt collection container.

Abstract: A surface cleaning apparatus including a housing supporting a suction source including a motor with an axle that rotates a fan and a dirt collection container having an elongate axis (A). The elongate axis (A) of the dirt collection container is transverse to an axis of the axle of the motor, and the axis of the axle of the motor is offset from the elongate axis of the dirt collection container.

Abstract: A surface cleaning apparatus (10) is described including a dirt collection container (18b) and an inlet passage (99) leading to the dirt collection container (18b) through which dirt-laden air is drawn by a source of suction. The apparatus further includes a moveable blocking member (120) positioned in the passage (99) where the blocking member (120) is moveable between a blocking position, in which the passage (99) is blocked or substantially blocked, and an unblocking position, in which air can pass through the passage (99). The apparatus includes a receiving formation (130) for receiving at least a portion of the moveable blocking member (120) when the blocking member is in its unblocking position.

Abstract: A tool for a surface cleaning apparatus includes a floor head, a connecting member for connecting the tool to a surface cleaning apparatus, and a passage for carrying dirt-laden air from the floor head to the apparatus. The floor head and connecting member are pivotally connected to each other about an axis A, the connecting member includes an articulated joint having first and second parts which are pivotable relative to each other about an axis B. Axis B extends transversely to axis A. The tool includes an electrical cable passage through which electrical cables may extend to provide an electric connection between the apparatus and an electrical component in the floor head.
