Abstract: A light emitting diode lighting assembly includes a display unit and lighting assemblies. The display unit includes a left vertical support on a left side, a right vertical support on a right side, and a front portion. The first lighting assembly is operatively connected to the left vertical support proximate the front portion and includes a first plurality of light emitting diodes and a first reflector. The second lighting assembly is operatively connected to the right vertical support proximate the front portion and includes a second plurality of light emitting diodes and a second reflector. The first reflector directs light from the first plurality of light emitting diodes toward the right side and the front portion and the second reflector directs light from the second plurality of light emitting diodes toward the left side and the front portion to uniformly illuminate contents of the display unit proximate the front portion.

Abstract: A display assembly with low voltage powered lighting includes a connection surface, a low voltage conductor, a power supply, and a board. The connection surface has a cavity and an aperture providing access to the cavity. The low voltage conductor is positioned within the cavity of the connection surface and is accessible through the aperture. The low voltage conductor is defined by 0.01 to 48.00 volts. The power supply is operatively connected to the low voltage conductor, and the power supply is set to 4 to 48 volts. The board includes a plurality of light emitting diodes and a driver. The driver interconnects the plurality of light emitting diodes and the low voltage conductor. The low voltage conductor provides power to any number of boards within the capability of the power supply.

Abstract: According to the present grinding method, a plurality of optical markers are formed by photolithography such that the markers are embedded in a chiplet having a magnetic head. Markers are preferably in the shape of a bar having predetermined height, width and length and are spaced from each other by a predetermined distance where one end of the bars are sequentially offset from each other by a predetermined amount. During coarse grinding of the magnetic head as the magnetic head surface material is ground away, the end-face of the bars, one at a time, become visible. The closer the grinding surface approaches the desired inductive throat or MR element height, more end-faces become visible. Coarse grinding continues until a predetermined number of end-faces become visible at which point the grinding process is terminated and the magnetic head is ready for the final lapping process.
