Abstract: Systems and methods which provide battery configurations for delivering high power while maintaining high energy density are described. Embodiments provide cylindrical batteries configured to deliver high energy density while having high power density at least in part through an electrode configuration disposing electrode material for the cathode and/or anode over an extended length of a longitudinal edge of the respective cathode or anode. An electrode configuration may provide for a continuous length of electrode material disposed along a longitudinal edge of at least one of the cathode or anode. Additionally or alternatively, an electrode configuration may provide for a plurality of electrode tabs of electrode material spaced out along a longitudinal edge of at least one of the anode or cathode.

Abstract: A router includes a motor unit and a base that receives the motor unit. A threaded shaft is supported on either the motor unit or the base. A slide is supported on the other of the motor unit and the base. The slide engages with the shaft in a first position of the slide in which micro-adjustments to a cutting depth are permitted. The slide disengages with the shaft in a second position of the slide in which macro-adjustments to the cutting depth are permitted. With a lever in a locked position, neither macro-adjustments nor micro-adjustments are permitted regardless of the slide being in the first position or the second position. With the lever in a micro-adjustment position, only micro-adjustments are permitted with the slide in the first position. With the lever in an unlocked position, the lever disengages the slide from the shaft to permit macro-adjustments.

Abstract: Systems and methods which provide lithium-ion battery configurations with high energy density are disclosed. Embodiments provide lithium-ion batteries comprising an anode that includes 30 to 85 wt. % silicon, thereby facilitating high energy density and high N:P ratio for the lithium-ion batteries. The high N:P ratio further enables fast charging and low temperature charging capabilities of the lithium-ion batteries.

Abstract: Centrifugal clutch mechanisms, and transmissions and lawnmowers having centrifugal clutch mechanisms are provided. A centrifugal clutch mechanism includes a clutch bell comprising an annular wall and a circular ring extending away from the annular wall to define an internal cavity, wherein the circular ring comprises an inward facing surface defining a drive surface. The centrifugal clutch mechanism also includes a plurality of centrifugal weights disposed in the internal cavity and an inward biasing element engaged with the centrifugal weights. The inward biasing element biases the centrifugal weights towards a disengaged position in which the centrifugal weights do not interface with drive surface, and upon application of a sufficient centrifugal force, the centrifugal weights are configured to transition to an engaged position in which the centrifugal weights interface with the drive surface.
