Abstract: Disclosed herein are hybrid drum shells and methods of forming such hybrid drum shells. Some embodiments include wood in addition to metal and/or another non-wood material. For instance, one or more metal (or other non-wood) plies or stave portions can be included. The inclusion of a non-wood element alters the vibration characteristics of the drum when struck by a drummer, thereby resulting in a unique sound profile that may be tuned by, for example, material selection.

Abstract: In a drum shell, the combination comprising the shell having multiple wooden curved plys, each ply having a grain extending in a characteristic direction, the grain direction of at least one ply extending crosswise relation to the grain direction of the next adjacent ply.

Abstract: The present invention relates to a method of dyeing polymeric substrates having pendent carboxyl groups, especially polyamides. The method comprises applying to a substrate a reactive dye solution and heating the substrate in the presence of a magnesium donor at a pH of greater than 9.0, such that the reactive dye forms a covalent bond with the carboxyl groups on the substrate. A dye composition for dyeing a polymeric substrates having pendent carboxyl groups is also disclosed.

Abstract: An optical dispersion system comprising a light source where light is directed to be illuminated from the system, a prismatic magnifier to expand a coverage area of the light illuminated from the light source and to deflect and magnify the light, and a removable front panel having a cutout area through which the light source illuminates.

Abstract: A system and methodology to evaluate an image of an object based upon multiple attribute threshold values is provided. In accordance with the invention, if an attribute reading from a sensor is between pre-defined threshold values, the sensor reading can be deemed acceptable. High and low thresholds can be provided to allow a user to set an acceptable range. These high and low thresholds can be applied to inspection tools (e.g., brightness sensors). For clarification, the high and low thresholds can be applied to any measurable attribute.

Abstract: Systems and methodologies that facilitate representation/detection of failed parts by employing an indicator component that annotates and points out a failed portion of a unit on its image taken by an image sensor. The indicator component can include: a boundary definition system, a dilation system and a mixture based analysis system. The annotated digital images can be saved in a memory of the image sensor or an external memory, for a display and presentation of a visual cue to an operator.

Abstract: Systems and methods are disclosed that facilitate permitting a user to select one of a plurality of job setups stored in a camera sensor. The plurality of job setups can be pre-programmed into the sensor utilizing conventional methods. During sensor operation, a user can select a particular application, and a simple signal can be generated for transmission over existing input/output lines to the camera sensor, upon receipt of which the camera sensor can initiate the particular job setup associated with the signal. Job setup signals can be formatted in binary utilizing HIGH and LOW voltages or can be transmitted as a simple Morse Code message and/or integer value.
