A method of computing a hologram by determining the wavefronts at the approximate observer eye position that would be generated by a real version of an object to be reconstructed. In normal computer generated holograms, one determines the wavefronts needed to reconstruct an object; this is not done directly in the present invention. Instead, one determines the wavefronts at an observer window that would be generated by a real object located at the same position of the reconstructed object. One can then back-transforms these wavefronts to the hologram to determine how the hologram needs to be encoded to generate these wavefronts. A suitably encoded hologram can then generate a reconstruction of the three-dimensional scene that can be observed by placing one's eyes at the plane of the observer window and looking through the observer window.

A chassis clings to a ship hull or other ferrous surface by a magnet that moves toward or away from the surface to adjust the magnet air gap and thus the attractive force. The magnet(s) can be the only clinging force or used with other sources such as a suction chamber or fluid jet drive. An internal magnet on a crank mechanism can pivot around a wheel rotation axis inside a wheel body having a non-ferrous traction surface or tire. The magnet gap is least at an angle perpendicular to the surface on which the wheel rests, and larger at an angle oblique to that, for varying the attractive force to two or more levels. The vehicle can be an autonomous hull maintenance device with sensors, controllers and actuators to sense, measure and clean away fouling.

The data defining an object to be holographically reconstructed is first arranged into a number of virtual section layers, each layer defining a two-dimensional object data sets, such that a video hologram data set can be calculated from some or all of these two-dimensional object data sets. The first step is to transform each two-dimensional object data set to a two-dimensional wave field distribution. This wave field distribution is calculated for a virtual observer window in a reference layer at a finite distance from the video hologram layer. Next, the calculated two-dimensional wave field distributions for the virtual observer window, for all two-dimensional object data sets of section layers, are added to define an aggregated observer window data set. Then, the aggregated observer window data set is transformed from the reference layer to the video hologram layer, to generate the video hologram data set for the computer-generated video hologram.

Embodiments in accordance with the present invention provide a perpendicular recording magnetic head whose dimensional dependency on the nonuniformity of magnetic field strength and distribution during manufacture is minimized, with narrowed tracks and without attenuation or erasure of adjacent track data while maintaining high magnetic field strength. According to one embodiment, a magnetic material (trailing/side shield) for creating a steep gradient of magnetic field strength is provided at a trailing side of a pole tip of a main magnetic pole piece and in a direction of the track width. The magnetic head is formed so that a gap (side gap length “gl”) between a side shield and a throat height portion of the pole tip progressively decreases with an increasing distance from an air-bearing surface, in a direction of an element height. That is, side gap length “gl” (2) at an element height position P2 is made smaller than side gap length “gl” (1) at an air-bearing surface position P1 so as to satisfy a relationship of gl(1)>gl(2).

A semiconductor device includes: a first substrate made of semiconductor and having first regions, which are insulated from each other and disposed in the first substrate; and a second substrate having electric conductivity and having second regions and insulation trenches. Each insulation trench penetrates the second substrate so that the second regions are insulated from each other. The first substrate provides a base substrate, and the second substrate provides a cap substrate. The second substrate is bonded to the first substrate so that a sealed space is provided between a predetermined surface region of the first substrate and the second substrate.

A battery assembly with a housing that contains a removable battery pack. The housing, which is sterilzable, has a head designed to couple to a power consuming device. The battery pack, which is not sterlizable, contains at least one rechargeable cell. The battery pack has a head dimensioned to fit the same charger socket that can receive a sterlizable battery. The battery pack has contacts that abut charger contacts. The housing has internal contacts. Collectively, the housing and battery pack are shaped so that, when the battery pack seats in the housing, the battery pack contacts abut the housing internal contacts. The housing internal contacts are connected to the housing external contacts for supply power to the power consuming device. A cover selectively holds the battery pack in the housing chamber.

A dual-frequency coaxial earphone has a shared magnet, which is interposed between a top board of a outer yoke and an outer disk of a inner yoke, wherein the outer yoke and the inner yoke each has a different polarity. A low-frequency voice coil of a low-frequency speaker part extends axially into and between an annular wall of the outer yoke and the outer disk of the inner yoke. An inner sleeve of the inner yoke extends into a first central opening of the outer yoke. Therefore, a high frequency of the high-frequency speaker part can pass through the inner sleeve so as to energize a central diaphragm of the low-frequency speaker part and to form a same phase as, and to output frequency synchronously with, the low-frequency speaker part. As such, the problem of intermodulation of distortion for the high and low acoustic frequencies can be solved, and that dimension of the earphone can be minimized.

An improved structure lamp pipe insert connector comprised of a locking connector component situated between upper and lower lamp pipes, the locking connector component comprised of a threaded rod, a lock sleeve fastened onto the threaded rod, and constraining rings respectively sleeved (not fastened) onto the two ends of the threaded rod and, furthermore, situated at the two sides of the lock sleeve. The interior of the constraining ring is a sloped surface and a plurality of detent slots are disposed along its inner circumferential extent and, after a spring is prepositioned on the sloped surface, it is then sleeved onto the threaded rod. Furthermore, there are revolving guide ring elements with beveled sides, each revolving guide ring element having guide blocks aligned with the constraining ring detent slot positions and capable of entry into the detent slots, thereby providing for the synchronous rotation of the revolving guide ring elements and the constraining rings. When the lamp pipes drive the constraining rings into rotation, the revolving guide ring element beveled sides are forced against the constraining ring sloped surfaces and become tightly ensconced within the inner circumference of the lamp pipes. As such, assembly is simple and enables user self-assembly and, furthermore, since each steel pipe can be disassembled, shipping dimensions are minimized.
