Abstract: A blow molded toy cycle has a female bearing area with tapered and recess sections. A fork has a corresponding male bearing area that includes a tapered section and an annular protrusion section. A protrusion spaced at a distance from the annular protrusion extends from the shaft and has a surface to contact a top surface of the body to secure the fork when the male and female bearing areas are in contact. The fork has integrally formed tabs that to bend around an axle to form a bearing area for the axle that allows the axle to rotate within the fork. A blow molded pedal attaches to a section of the axle and has a series of ribs disposed between side sections to form a bearing area that allows the pedal to rotate around the axle. Two rear and one front wheels attach to the body and fork respectively.

Abstract: An insert for protecting articles to be stored in a protective case. The insert is generally hollow and formed of a flexible thermoplastic material. The insert may be formed by a blow-molding process. The insert is shaped to fit within a protective case, which is also often formed by a blow-molded process. The material used to form the insert is less dense than that of the material used to form the protective case, and therefore the insert material is less stiff, softer, and more flexible.

Abstract: Systems and methods are described for extending the dynamic range of imaging systems, and more particularly fluorescence or luminescence imaging systems, having low optical background and a linear detector response. Images of a sample at each of a set of exposure times are acquired, a system-level dark estimate for each exposure time is subtracted from each image to form dark-corrected images, and the different exposures (dark-corrected images) are merged into a wider dynamic-range image. Typically merging is performed on a pixel-by pixel basis.

Abstract: A method of detecting the condition of a turf grass is described. According to one aspect of the invention, the method comprises steps of attaching an active sensor to a mower; traversing a section of turf grass; and processing the output of the sensor. A device for detecting the condition of turf grass is also disclosed. The device comprises an array of illuminating devices generating a pattern of illuminating light; a detecting device receiving a pattern of reflected light which is coincident with the pattern of illuminating light; a detecting device adapted to detect stray light from the array of illuminating devices; and a feedback loop controlling the array of illuminating devices. A system employing the device is also disclosed.
