Abstract: A polarization splitting backlight module for efficiently converting a non-polarized light beam emitted from the light source into a single polarization state is disclosed. The polarization splitting backlight module of the present invention comprises an under plate with a ridged lower surface, a light source, a special reflection film, a scattering structure, a substrate and a polarization splitting film. The light beam emitted from the light source is introduced into the scattering structure between the under plate and the substrate. After a series of processes, such as scattering, reflection, phase retardation and polarization beam-splitting, the light beam will pass through the polarization splitting film being of a single polarization state such that it could be utilized by electro-optical systems, such as liquid crystal displays. The present invention converts light beams into a single polarization state, and the efficiency thus is higher than that of a conventional backlight module. The present invention achieves brightness levels that are almost twice that of conventional backlight module.

Abstract: A piezoelectric transducer apparatus comprises at least one piezoelectric unit and a body structure. Each of the at least one piezoelectric unit has a piezoelectric block and at least one pair of electrodes. Each electrode is adhered to one surface of the piezoelectric block. Each of the at least one piezoelectric unit is adhered to the surface of the body structure with the electrode exposed externally. The transducer apparatus has a generalized sensor equation which can be modeled in a fourth-order partial differential equation mathematical system. At least one of the electrodes or the piezoelectric block of each of the at least one piezoelectric unit has a shape matched to a desired body strain pattern existing in the body structure wherein the electrode of each of the at least one piezoelectric unit may excite a strain pattern in the body structure that is the same as the desired body strain pattern. The body structure of any structural configuration may have a resolved electrode shape that results in the disengagement of the phase and gain characteristics of the piezoelectric construction based on that particular body structure.

Abstract: A reflective-type diffraction grating structure for use in color display devices such as liquid crystal displays (LCDs). It contains: (1) a plurality of micro-lenses each having a smooth top surface and a blazed zig-zag-shaped grating surface at the bottom; (2) an optical coating formed below the zig-zag-shaped grating surface; and (3) a reflective member formed below the optical coating. With the cooperative actions of the zig-zag-shaped grating surface, the optical coating layer, and the reflective member, an incident light, when reflected, is separated into repeated sequences of red, green, and blue color components and a black matrix segregating the red, green, and blue color components. A sequence of micro-light valves are placed in the path of the reflected incident light to block the undesired color components. The reflective-type diffraction grating structure dispenses with the need for the various layers of color filters. As a result, it improves the brightness of the image and reduces power consumption, as well as reducing the manufacturing cost.

Abstract: An apparatus and method for automatically adjusting the gram load and static attitude in a head suspension assembly comprising one or more lasers, a fiber optic switch, a measurement apparatus and a computer control means. The fiber optic switch includes a plurality of fiber optic lines which direct the output of the laser to well-defined regions on the suspensions in a disk drive. Irradiation of the suspension by the laser causes a load change which alters the static attitude change in the slider. In the method of the present invention, the initial gram load or static attitude is measured by the measurement apparatus and the control means calculates how much energy is required to cause the change needed to achieve the desired condition. Other information, such as the type of laser to be used is also specified by the control means. The laser then delivers output to the suspension through the fiber optic line having an angled end and the static attitude or gram load is remeasured to determine if additional adjustment is required.

Abstract: An interference apparatus is disclosed wherein the high-visibility quadrature interference signals are obtained by making a pair of polarization beamsplitter, a 45-degree oriented quarter-waveplate and four light-beam detected photodiodes. A three-dimensional interference optical configuration is made. The test-surface light beam and reference light beams are traveled on this optical configuration. The test-surface light beam and reference light beams have orthogonally linearly polarization state with each other. After they pass through the quarter-waveplate, one right circularly polarized light beam and one left circularly polarized light beam are produced. The vector sum of these two circularly polarized light beams is again a linearly polarized light beam which is then divided into two light beams by a non-polarization beamsplitter. A pair of polarization beamsplitters, whose axes are 45 degrees apart, are utilized to create the 90 degrees phase difference of the light beam intensity signal measured at the photodiodes.

Abstract: Disclosed is a method and apparatus for sensing the vibrational response of a slider of predetermined dimensions during contact with one or more surface asperities on a recording surface, separating the response into its individual bending mode frequency component responses, determining one or more bending mode frequency responses which display monotonic behavior with increasing asperity interference, and designing a mode selection sensor optimized to detect the monotonic bending mode frequency identified. The mode enhanced sensor is designed by first analyzing the stress distribution of the slider corresponding to the monotonic bending mode frequency, identifying regions of the slider which experience substantially positive or substantially negative stress, and partitioning the upper conductive layer of a piezoelectric sensor to form a partitions corresponding to each of the identified regions. The sensor may be further enhanced by tailoring the partitions to exclude undesirable stress contributions.
