  • Patent number: 10807255
    Abstract: An electrical hair trimmer including a mounting device; a blade configured to be mounted to the mounting device; a housing; and a cap configured to be attached to and detached from the housing so that when attached to the housing the cap covers one or more openings at a top of the housing preventing debris from falling into an inner chamber of the housing. The mounting device may project outward from the housing; and the cap may have a first opening which allows it to be slipped on to the housing, over the mounting device to cover the one or more openings at the top of the housing, and allows the cap to be slipped off of the housing, by passing the mounting device through the first opening; and the mounting device projects outwards from the cap through the first opening when the cap is attached.

  • Patent number: 10531889
    Abstract: A releasably attached surgical scissor spray shield is mounted immediately proximate to the scissor blade. The shield controls the spray at the source thus shielding not only the user, but all personnel in the vicinity when an umbilical cord or the like is cut. The mounting mechanisms for the shield releasably, yet securely attaches the spray shield to the scissors so the shield remains immediately proximate to the scissor blades and umbilical cord yet does not restrict the opening of the scissor shear blades. The shield is mounted in close proximity to the cutting operation of the scissors to thereby deflect blood spray immediately adjacent to the source of the spray. The shield does not restrict the operational movement of the scissor blades and arms during the cutting operation.

    Abstract: Effectiveness of video content is predicted using an automated or semi-automated analysis process operating on a computer. Video content is analyzed using image and audio data processing to assign a collection of attributes to a video ad. The collection of attributes is correlated to a historical effectiveness (e.g., click-thru rate) of past video ads in the same or similar attribute space to obtain predicted ad effectiveness. Differences between the collection of attributes and historical attribute spaces of greater effectiveness may also be determined and reported in the form of suggestions for improving the effectiveness of the ad.

    Abstract: A cutting tool with first and second pivoted shearing blades has a guide member mounted to the first blade for transverse movement relative to the first blade and toward and away from the second blade. The guide member has a transverse restraining surface that confronts a transverse guided surface of the second blade during cutting of a workpiece to resist axial separation of the cutting edges away from the cutting plane. A yieldable, resettable mechanism enables release of an uncut cable captured by the guide member in the event the planned cut is in error or must be postponed. Examples include a ball detent, a magnet, an over-center extension spring arrangement and a torsion spring.

    Abstract: An improved pole pruner for pruning a limb from a tree is provided which includes structure which grabs or grasps that portion of the tree limb to be detached as the cutting blade of the pole pruner severs the tree limb from the tree thereby preventing the severed tree limb from falling downwardly and injuring the operator of the pole pruner. The operator of the pole pruner may maneuver the pole pruner to a location wherein it is safe to release the severed tree limb from the pole pruner.

  • Publication number: 20100071218
    Abstract: The present invention relates to a switch-operating mechanism. In particular, the present invention relates to a switch-operating mechanism for a power tool, such as a pruning tool. Described is a switch-operating mechanism for a powered tool including a working head having first and second cutter members. The switch-operating mechanism further includes a lever moveable between first, second, and third operative positions. In operation, positioning of the lever in the first operative position provides a ‘power off mode’ in which the power supply is disconnected; movement of the lever into the second operative position causes the at least one of the cutter members to move to a first blade position; and movement of the lever into the third operative position causes the at least one of the cutter members to move to a second blade position.
