  • Publication number: 20240087142
    Abstract: A method of tracking a user's toothcare activity comprises receiving video images of a user's face during, e.g. a toothbrushing session, and identifying, in each of a plurality of frames of the video images, predetermined features of the user's face. The features include at least two invariant landmarks associated with the user's face and one or more landmarks selected from at least mouth feature positions and eye feature positions. Predetermined marker features of a toothcare appliance, e.g. a brush in use are identified in each of the plurality of frames of the video images. From the at least two invariant landmarks associated with the user's nose, a measure of inter-landmark distance is determined. An appliance length normalised by the inter-landmark distance is determined. From the one or more landmarks selected from at least mouth feature positions and eye feature positions, one or more appliance-to-facial feature distances each normalised by the inter-landmark distance is determined.

  • Patent number: 8881443
    Abstract: A lock for a firearm is disclosed. The firearm has a grip safety and a sear engageable to a biased hammer in a cocked position and releasable by a trigger. The lock includes a housing defining a bore within which a mainspring biasing the hammer is revived. A latch is rotatably mounted to the housing and has a grip safety arm and a cam follower, and has a first rotational excursion with the grip safety arm in engagement with and restricting the grip safety to block movement of the trigger, and an opposed second rotational excursion with the grip safety arm in disengagement from the grip safety to unblock depression of the grip safety and movement of the trigger. An actuator is mounted to the housing and cooperatively linked to the latch, and provides motive force for positioning the larch in the first rotational excursion and the second rotational excursion.
