Title: Method and apparatus for finding horizons in 3D seismic data.
Inventor: HILDEBRAND HAROLD A
IPC: G01V1/30
Filed: 1992-07-06
Abstract: A method and apparatus of rapidly generating horizon maps from a three dimensional volume of seismic traces is disclosed. During batch processing of the digital data representing trace wavelets, "1"'s or "0"'s are determined for each seismic trace of the volume. A bit volume is produced of which a "1" at a depth of a trace indicates that a horizon exists at that depth and at other depths of "1"'s of adjacent traces which are within a predetermined depth. In a real time mode, an explorationist selects a seed point thereby identifying a "1" on a particular trace at a particular depth. An automatic scanning procedure finds all other "1"'s at depths of adjacent traces. Each found "1" of adjacent traces is redesignated a seed point and the process is continued until no more "1"'s can be found. A horizon map is created from the depths of each found "1". An alternative method and apparatus is disclosed by which such bit volume is replaced with a compressed trace volume where each bit of the bit volume is replaced with a numerical value corresponding to the precise depth location of the attribute extremum represented by the bit. Such depth values are stored consecutively to form compressed traces. Interpolation of wavelets to find maximum or minimum attributes of such wavelets identifies depths above or below a bit of the bit volume which allows the production of an interpolated compressed trace volume.

Title: Bath aerating mat with air outflow plates
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1996-05-18
Abstract: The spray mat has a plate (1) which is made from a soft material with several holes (1a) in it of various geometries. At the foot end, there is a location (1b) for the central distributor switch (4). A head cushion (5) has a hoop (6a) on the back of it for the users hand. The outlet units (2) are pressed into the holes in the plate and have a sucker underneath them. In the outlet units is a flexible fleece-like material insert. The spray characteristics are determined by the compressed air passing through the fleece. Due to their elasticity, the fibres of the fleece are tightly packed when low pressure is being used but with high pressure they become loose. With low air pressure therefore, a fine spray is produced but with high pressure, a coarse massage spray is produced.

Abstract: An improved elastic member (24) for micromechanical devices
(12). The micromechanical device (12) includes a stationary
member (28) and a moving member (26) which are connected
together by a elastic member (24). Because of repeated and
frequent movement of the moving member (26), the elastic member
(24) can become permanently flexed or deformed, resulting in
poor operation of the device. Nitrided aluminum and non-aluminum
alloys can be used to form a metal film from which the
elastic member (24) is formed, either as polycrystalline films
or as amorphous films. These alloys have isotropic elastic
properties, high tensile strength and form smooth films when
deposited.

Abstract: A process is described of forming an electroluminescent (EL) display panel formed from an EL 
laminate having a phosphor layer (22) sandwiched between a front and a rear set of intersecting 
address lines (14,24), the rear address lines (12) being formed on a substrate (12) having 
sufficient rigidity to support the laminate and the phosphor layer being separated from the rear 
address lines by one or more dielectric layers (18,20); the process comprising the steps of: (a) 
providing a substrate formed with a plurality of through holes (32) patterned to be proximate the 
ends of the address lines to be subsequently formed; (b) forming a conductive path through each 
of the through holes in the substrate to provide for electrical connection of each address line, 
subsequently formed, to the voltage driving circuit (30); (c) forming the rear spaced address lines 
(14) on the substrate (12), one end of each line ending adjacent a through hole (32) and being 
electrically connected with the conductive path therethrough; (d) forming a dielectric layer 
(18,20) on the rear address lines (14); (e) forming the phosphor layer (22) above the dielectric 
layer: (f) optionally forming a transparent dielectric layer on the phosphor layer; and then (g) 
forming the front spaced address lines (24) on the underlying phosphor or transparent dielectric 
layer, one end of each line ending adjacent a through hole and being electrically connected with 
the conductive path therethrough.  
     The invention also describes a method for laser scribing a pattern in a planar laminate (preferably 
an EL panel) having at least one overlying layer (e.g. a transparent layer for forming the front 
address lines (24)) and at least one underlying layer (e.g. a phosphor layer (22)); the method 
comprising: applying a focused laser beam on the overlying layer side of the laminate, said laser 
beam having a wavelength which is substantially unabsorbed by the overlying layer (24) but 
which is absorbed by the underlying layer (22), such that at least a portion of the underlying 
layer (22) is directly ablated and the overlying layer (24) is indirectly ablated throughout its 
thickness (thereby forming individual front address lines (24)).

IPC: G10H3/14
Filed: 1996-03-11
Abstract: A percussion pad includes an upper surface (28) that may 
be struck to activate the pad and a lower surface (18) on 
which is mounted a sensor (20) for detecting when the 
upper surface (28) is struck. An enclosed cavity (24) is 
located above the region of the lower surface (18) on 
which the sensor (20) is mounted. The cavity (24) 
prevents the shock wave of an impact above the sensor (20) 
from being transmitted directly to the sensor (20). 
Because shock waves will not propagate significantly 
around the cavity (24) or along oblique paths from other 
parts of the surface (28), the sensitivity of the pad is 
uniform over the surface (28). An outer layer (26) of the 
pad is preferably formed of rubber-like material to reduce 
the acoustic sound of an impact and give a drum-like feel.

Abstract: A process for treating and purifying water for swimming pools uses water softeners, filters, pumps and pipes for circulating water. The water is treated with ion exchangers (6) to remove acids and water hardness components and the softened water is used to fill a pool (1). Lime water (8), comprising a clear saturated solution of (hydrated) lime in water, is added to the pool to create a lime-carbonic acid equilibrium which converts any carbon dioxide in the water into carbonate in order to precipitate phosphate and sulphate as sparingly soluble calcium salts, as well precipitating body substances (eg. dead skin), creams and bath oils as lime soaps. Inorganic oxidation products generated by sunlight are precipitated as calcium ions, and small suspension or sediment solids not normally capable of being filtered are adsorbed onto calcite. The water is passed continuously through a cycle consisting of pipes (13, 19, 20) , pumps (17), valves (14, 18) and filters, forcing at least some of the water to flow a bed of crushed limestone to keep pH above 7. More limewater is optionally added to maintain the lime-carbonic acid equilibrium. Lost water is replenished with fresh acid- and hardness-free water to prevent water in the pool becoming too salty. The apparatus is also claimed.

Abstract: A wave generation circuit is disclosed, in which a
complex waveform can be generated without increasing the
ROM data amount or increasing the reading rate. Waveform
data relating to a waveform and the generation thereof
are stored in a ROM (651) for each cycle. An address signal
for reading the waveform data sequentially is produced
sequentially by an address generation circuit (71,81). The
waveform data read out are sequentially reproduced into a
waveform signal by a waveform data output circuit (73,84). In a
wave generating circuit including the ROM and the address
generation circuit (71,81),the waveform data includes the
extension information instructing to extend and reproduce
the waveform data for a particular cycle. An extension
and control circuit (72) included in the wave generation
circuit decides on the presence or absence of the
extension information from the read waveform data, and in
the presence of the extension information, controls the
waveform data output circuit (73,84) to maintain the output of a
corresponding waveform signal while at the same time
controlling the address generation circuit (71,81) to retard the
generation of the address signal. The wave generation
circuit can generate a single waveform data in an
extended form according to the extension information when
the same data continues for a plurality of cycles,
thereby reducing the waveform data amount and the ROM
capacity.

Abstract: Artwork is imparted to plastic discs such as CDs, CD ROMs, and DVDs (digital video discs) by exposing a layer of photoresist material on a substrate to light from an original image of the artwork. The material of the photoresist layer is exposed to different depths by different intensity light from different image regions. Where the image is dark, the exposure is to relatively shallow, random depths. Where the image is light, the full thickness of the photoresist layer is exposed. Development of the photoresist layer removes the exposed photoresist material. The surface features of the developed photoresist layer and any uncovered substrate are transferred to a member used in forming a surface of the plastic disc, thereby visibly embossing the image in the disc. <IMAGE>
