Abstract: Systems and method are disclosed herein that relate to support for virtual Time-Sensitive Networking (TSN) bridge management, Quality of Service (QoS) mapping, and TSN related scheduling in a cellular communications system. In some embodiments, a method performed by one or more network nodes of a cellular communications system operating as a virtual TSN bridge of a TSN network comprises providing, to a controller associated with the TSN network, parameters that relate to capabilities of the virtual TSN bridge. The parameters that relate to the capabilities of the virtual TSN bridge comprise a first parameter that defines a clock accuracy of an entity in the cellular communications system that operates gating control for the virtual TSN bridge and a second parameter that informs the controller associated with the TSN network that the virtual TSN bridge or a particular egress port of the virtual TSN bridge is restricted to exclusive gating.

The external device may comprise a camera arranged to produce image data, and a processor arranged to process an image of the light source to obtain the brushing data.

Abstract: An electric toothbrushing device is disclosed, the device comprising means (16) for producing vibration of a toothbrush head (14), means (24, 32, 40, 42, 44) for producing an orientation signal indicating of an area of the mouth being brushed, and means (47, 48, 49) for producing a pressure signal indicating a pressure applied to the toothbrush head. The device further comprises processing means (46) arranged to link values of the orientation signal with values of the pressure signal in order to provide feedback to a user regarding a brushing pressure applied to each of a plurality of different areas of the mouth. By linking values of the orientation signal with values of the pressure signal, the user can be better informed about which parts of the mouth are being or have been brushed too hard. This can help the user to correct their brushing technique.

Abstract: An electric toothbrushing device is disclosed, the device comprising vibration means for producing vibration of a toothbrush head and a controller for controlling the vibration means. The device also comprises a motion sensor for sensing motion of the toothbrushing device to produce motion data, and a signal analysis unit for analysing the motion data to produce a feedback signal. The controller is arranged to adjust the vibration produced by the vibration means in dependence on the feedback signal. Such a configuration can be used to improve the feedback provided to the user and/or help to correct deficiencies in the user's brushing technique.

Abstract: A system for determining the orientation of a toothbrush (4), the system comprising an orientation sensor (27) configured for attachment to a toothbrush (4) and one or more processors (29) configured to receive orientation information from the orientation sensor (27). The one or more processors (29) are further configured to determine whether the sensor (27) is in a first orientation (41) or a second orientation (33). The first orientation (41) corresponds to use of the toothbrush (4) on a surface of teeth on the left (42) of a user's mouth. The second orientation (33) corresponds to use of the toothbrush (4) on a surface of teeth on the right (40) of a user's mouth.

Abstract: A surgical blade package facilitates the mounting of a surgical blade on to the forwardly-projecting cleat on a scalpel handle; and following use in the O.R., the surgical blade package facilitates stripping the used blade off the scalpel for disposal in a sharps container. The cleat is inserted beneath the rear end portion of the blade, and between the blade and the bottom wall of the blade package; and forward and upward movement of the scalpel snaps the blade on to the scalpel in a continuous movement. The opposite procedure is used to demount the used blade from the scalpel and encase it in the original blade package for disposal in a sharps container.
