Abstract: A starting system for an internal combustion engine automatically operates a starting feature on a carburetor associated with the engine. The starting system includes a cam with a bearing mounted on the crankshaft. The bearing is secured so that its inner race will always rotate with the crankshaft. The cam has bosses on one side and is shaped such that it includes a base and a lobe with an outer surface surrounding the cam. At least one spring-loaded pawl is mounted on the flywheel. The pawl is biased to engage a cam boss so as to cause the cam to rotate with the crankshaft during a start-up process. A spring loaded rocker arm is pivotally mounted adjacent the cam. The rocker arm has a roller assembly configured to ride on the outer surface of the cam. As the cam rotates, the roller assembly riding on the cam surface is pushed outward by the cam lobe. A throttle cable is attached at a first end to the rocker arm and at its opposite end to the starting feature on the carburetor. When the roller assembly ramps up the lobe, the throttle cable is pulled into an extended position to actuate the starting feature of the carburetor.

Abstract: This invention provides a method for identifying lawn grass comprising capturing an image of the terrain in front of a mower, segmenting the image into neighborhoods, calculating at least two image statistics for each of the neighborhoods, generating a binary representation of each image statistic. The binary representation of each image statistic is generated by comparing the calculated image statistic values to predetermined image statistic values for grass. The method further comprises weighting each of the binary representations of each image statistic, and summing corresponding neighborhoods for all image statistics. A binary threshold is applied to each of the summed neighborhoods to generate a binary map representing grass containing areas and non-grass containing areas.

Abstract: An automatic decompression mechanism for selectively actuating a cylinder valve of an engine so as to reduce the starting force required to start the engine. The mechanism includes a cam gear, a centrifugal member, and a cover member comprising an integrally formed biasing means for biasing and retaining the centrifugal member in the cam gear. The biasing means urges the centrifugal member into a decompression position when the cam gear is rotating at a lower speed, wherein a projecting portion of the centrifugal member actuates the valve mechanism to reduce the starting force required to start the engine. During normal engine operation, the centrifugal member pivots into a non-decompression position wherein the projecting portion of the centrifugal member recedes below the cam profile surface so as to prevent the projecting portion from actuating the valve mechanism.

Abstract: A flexible centering liner (24) for a handheld tool, such as a string trimmer, which includes a work tool assembly (14), and a drive motor (16) connected by a drive shaft (20). The drive shaft (20) is centrally held within a shaft boom (12) by a centering liner (24). The centering liner has a central sleeve (26) with a chamber for receiving the drive shaft (20). Extending from the central sleeve (26) supporting ribs (30) brace the centering liner (24) against an inner wall surface (33) of shaft boom (12). The ribs (30) intersect the central sleeve (26) at approximately a 90 degree angle, and then curve so that an outer body section of each rib is generally parallel to a tangent of the central sleeve (26). Preferably, the central sleeve (26) and the ribs (30) are extruded as a single body. The cross section of the ribs (30) taper or become thinner towards their distal ends (32). The rate of taper controls the flexibility characteristics of the ribs (30).

Abstract: A method of manufacturing injection-molded components having complex features is disclosed. Prior methods typically require the use of a three-piece mold system to form an injection molded component having a complex feature, such as a lawn mower hood having a parabolic shaped front. With the development of a new rigid type of reflective material the present method can thereby utilize a two-piece mold system to form an injection molded component having complex features such as a lawn mower hood having a C-shaped open cavity located at the front of the hood.
