Abstract: The present specification relates to a power tool comprising an input shaft and an output shaft and a two-speed power transmission comprising a planetary gear and a gear shift assembly for directing torque through or past the planetary gear comprising a driving member, a driven member and an axially movable coupling sleeve arranged to intercouple in a first position the driving member and the driven member and to intercouple in a second position the planetary gear and the driven member. A linear actuator is arranged to displace the coupling sleeve between the first and second position, wherein the linear actuator comprises a linearly movable push bar arranged for displacing the coupling sleeve. The present specification also relates to a method in and a two-speed power transmission for such a power tool.

Abstract: The present specification relates to a power drill, comprising a housing in which a motor is arranged, and a front and rear bearing arranged to support an axle assembly adapted to engage a drill attachment, wherein said axle assembly and at least one of said front and said rear bearing further form an additional assembly movably arranged with respect to said housing, said power drill further comprising a force transducer arranged at said front end of said housing and axially supported by said housing, and wherein said additional assembly is axially supported by said force transducer, said force transducer thereby being configured to output a signal representing an axial force acting on said additional assembly. The present specification further relates to a force transducer for such a power drill and a detachable front part for a power drill.

Abstract: Systems and methods for grading the appearance of seeds are disclosed. In an embodiments, a system comprises: a memory device configured to store one or more color thresholds and a processing device communicatively coupled to the memory device. The processing device is configured to: receive data corresponding to a digital image, wherein at least a portion of the digital image includes a representation of a plurality of seeds; divide the digital image into a plurality of sections; and compare an amount of color included in a section of the plurality of sections to a color threshold of the one or more color thresholds.
