  • Publication number: 20250144837
    Abstract: A handheld cutting tool includes a motor, a driven gear coupled to the motor and a sprocket coupled for co-rotation with the driven gear, a housing, a guide bar extending from the housing, a chain supported on the guide bar and engaged with the sprocket such that rotation of the sprocket moves the chain along the guide bar, a battery pack removably coupled to the housing, the battery pack including a foot portion on which the handheld cutting tool is supported in an upright position, and one or more support faces on which the handheld cutting tool is supported in a horizontal position, the one or more support faces extending forward of the housing, the one or more support faces defining a face plane that is non-intersecting with the foot portion.

  • Patent number: 12269187
    Abstract: A handheld cutting tool includes a motor, a driven gear coupled to the motor and a sprocket coupled for co-rotation with the driven gear, a housing, a guide bar extending from the housing, a chain supported on the guide bar and engaged with the sprocket such that rotation of the sprocket moves the chain along the guide bar, and a battery pack removably coupled to the housing, the battery pack including a foot portion defining a base plane. The center of gravity of the handheld cutting tool is located above the foot portion when the handheld cutting tool is stood upright on the foot portion, thus permitting the handheld cutting tool to balance only on the foot portion of the battery pack.

  • Patent number: 11872718
    Abstract: A handheld cutting tool includes a housing including a motor housing portion, a drive housing portion, and a handle portion extending from one of the motor housing portion or the drive housing portion. A motor is located in the motor housing portion. A driven gear is coupled to the motor for receiving torque therefrom. A first guard extends between the handle portion and one of the drive housing portion or the motor housing portion, and a second guard extends between the drive housing portion and one of the handle portion and the motor housing portion. A guide bar extends from the drive housing portion at an angle offset relative to the handle portion and the first and second guards. A chain is supported on the guide bar, and a battery pack is removably coupled to a bottom part of the handle portion.

  • Patent number: 8557525
    Abstract: The present invention relates to a composite metastasis score (“cMS”) based on expression of a 14-gene molecular signature (referred to as a metastasis score, or “MS”) in combination with progesterone receptor (PR) expression that is useful for predicting breast cancer metastasis. In preferred embodiments, the cMS is determined by applying weighted coefficients to MS and PR. The present invention provides methods and reagents for detecting and profiling the expression levels of these genes, and methods of using the expression level information for predicting risk of breast cancer metastasis, among other embodiments.
