A drum dampening device includes a foam pad adapted to be selectively engageable with drum wires on the drum. The foam pad is configured to dampen vibrations of the drum wires when the foam pad is engaged with the drum wires. A support plate is coupled to the foam pad, and a base plate is coupled to the support plate. An adjustment lever is coupled to the support plate and the base plate. The adjustment lever is selectively transitional between a first position and a second position, with transition of the adjustment lever from the first position toward the second position causing at least a portion of the support plate to move away from the base plate resulting in engagement of the foam pad with the drum wires.

A percussion instrument mount includes a base that supports a percussion instrument in a playing position. The percussion instrument mount also includes a swing arm that is coupled to the percussion instrument, and is also coupled to the base via a joint such that the swing arm rotates about the joint from an equilibrium position in response to a playing impact on the percussion instrument. The percussion instrument mount still further includes a playing impact energy absorber that provides a restoring force to the swing arm so as to return the swing arm to the equilibrium position.

An apparatus captures an image of a measuring instrument that is captured by an imaging apparatus, sets an area in the image as an edge detection processing target in response to a user operation, and executes edge detection processing on the set area in the image. Further, the image processing apparatus sets a value for correcting a position of a detected edge portion. The image processing apparatus corrects the position of the detected edge portion based on the set value and calculates a value indicated by a pointer of the measuring instrument according to the corrected position of the edge portion.

An instrument cluster assembly includes first and second light emitting elements. The first and second light emitting elements are spaced apart from one another. An optical element is positioned opposite the first and second light emitting elements. The optical element is configured to reflect or diffuse light from both the first and second light emitting elements so that light rays from the first and second light emitting elements are merged or cross one another.

A display device includes a first polarizing plate including a first polarization region and a first design region, a second polarizing plate including a second polarization region and a second design region, and a third polarizing plate including a third polarization region. A transmittance of light oscillating in a first direction of the polarization regions is maximized, and the design regions are transparent to light regardless of the oscillation direction of light. The first and second polarizing plates are arranged at a distance from each other along a path of the light, the first direction in the first polarization region and the first direction in the second polarization region are different from each other. The third polarizing plate is arranged such that the first direction in the third polarization region is positioned between the first direction in the first polarization region and the first direction in the second polarization region.

A display panel provided with a protective film includes a display panel and the protective film that is provided on a display surface of the display panel, in which the display panel is provided with a first through-hole passing through the display panel in a thickness direction, the protective film includes a first protective film, the first protective film is provided with a second through-hole passing through the first protective film in the thickness direction, the first through-hole and the second through-hole are in communication with each other and form a through-hole, the first protective film includes a first grip portion at a peripheral edge portion of the first protective film, and the first protective film includes a dividing portion that continues from the second through-hole to an end side of the first grip portion.

An instrument includes: a liquid-crystal display device including a display element and light sources provided along one side surface extending in the Y direction of the element; a first case having a reference positioning pin, and other positioning pins; and a second case having a reference hole into which the reference positioning pin is inserted, other holes into which the other positioning pins are inserted, a first region in which a first pointer-type instrument is provided, a second region in which a second pointer-type instrument is provided, and a third region in which the liquid crystal display device is provided between the first region and the second region. The third region has an edge corresponding to the position where the side surface 4a is disposed, and the reference hole is provided on the edge side with respect to the center of the third region in the X direction.

A tachometer display system and method is provided. In one embodiment, a tachometer display system includes a tachometer for indicating a plurality of engine speeds. The tachometer is configured to display a current engine speed based on a current gear ratio of a manual transmission. At least two synchronous shift point indicators are displayed at variable locations near the tachometer. Each synchronous shift point indicator is displayed near a location on the tachometer associated with an engine speed that corresponds to a transmission input shaft speed for a downshifted gear ratio of the manual transmission from the current gear ratio.
