Abstract: A small object detection using meaningful features and generalized histograms includes providing at least one pixilated image. A region of interest is extracted from the pixilated image. A statistogram of the region of interest is generated. The statistogram is searched to determine at least one maximal meaningful interval of the region of interest. The maximal meaningful interval is output in a tangible medium.

Abstract: A guitar-family-characteristic-sound selector switch (63) is incorporated into an electric guitar and used in conjunction with the normal guitar pickup selector switch (62) and the volume and tone controls. This guitar-family-characteristic-sound selector switch invokes different pickup (61) combinations and resistance/capacitance/inductance circuitry (68) in order to generate sounds characteristic of at least two other guitars in addition to the normal sound of the host guitar. In one implementation, the family selector switch is a single user controllable switch that makes the system is intuitive in that a single guitar-family-characteristic-sound selector switch is all that needs to be operated to put the guitar in the mode of sounding like one of three or more styles of guitars following such selection; the pickup selector, volume and tone controls are used in the usual manner.

Abstract: A pair of clamps for mounting a level to a joist. Each clamp includes a pair of spaced apart spring biased arms having first ends for gripping the joist. A mounting hole at the lower end of each clamp receives the opposite end of a level which is releasably secured therein. The method of measuring the level of a member includes the steps of mounting the clamps and level to the joist to be measured.
