Title: Generating areas of shadow in 2d image of 3d world
Inventor: KLOTZ KARL-HEINZ
IPC: G06T15/10
Filed: 1997-03-22
Abstract: Image data representing a three dimensional view is processed to produce a rendered two dimensional image plane. Data including a definition of a light source 1003 is considered and shadow planes 1007 are calculated with respect to said light source. A first characteristic is identified for an edge and a second characteristic of said edge is also identified. These characteristics may be references to the relative positions with respect to viewing directions and an indication as to whether the edge is shared with another polygon eg. 1008. In response to these identifications a data plane is incremented or decremented in an amount responsive to the identified combination on a pixel-by-pixel basis. Each shadow plane 1007 is designated as positive if the viewing vector goes into the shadow volume and negative for an exiting vector. Vector through point 1006 on polygon 1008 intercepts positive plane 1007 only, designating a shadow pixel, when the shadow volume 1004 does not intercept the polygon, eg at 1005 or at the far side of the volume, no plane is intercepted or positive and negative planes cancel out. A non-shadow pixel is designated. See Figs 13 and 14 for full algorithm.

Title: Channel allocation method
Inventor: HAYATA YASUNOBU
IPC: H04W28/08
Filed: 1998-07-14
Abstract: A channel allocation method is provided for a communication system, the method comprises the steps of detecting congestion of communication channels at a base station and allocating a control channel as a new communication channel when a conversation request is given from a mobile station. When conversation is terminated on the new conversation channel or a vacant conversation channel is detected at the base station, the new conversation channel is restored to its control function. In order to avoid jamming when the control channel is allocated as a conversation channel, the base station transmits a low frequency tone to other mobile stations to inform of utilization of the control channel for conversation, while adjacent base stations stop transmitting control signals.

Title: Multiple active computer generated hologram
Inventor: SLINGER CHRISTOPHER WILLIAM
IPC: G02B5/32
Filed: 1997-05-16
Abstract: Apparatus which allows selection and generation of a variety of hologrammatic optical wavefronts. A device, which comprises a substrate layer of varying thickness and an electro optic layer, with a voltage dependent refractive index mismatch between the two, is used to modulate transmitted light, thus generating a hologrammatic wavefront. Said modulation can be changed by variation of an applied voltage and this changes the wavefront which is generated. The range of wavefronts which can be generated is defined by the distribution of substrate layer thicknesses across the device.

Title: Method of assaying downhole occurrences and conditions
Inventor: SMITH LEE MORGAN
IPC: E21B49/00
Filed: 1997-03-21
Abstract: A method of assaying work of a bit (10) of a given size and design comprises the steps of drilling a hole with the bit (10) from an initial point (I) to a terminal point (T) and recording the distance between the initial and terminal points. Electrical incremental actual force signals (18) are generated, each corresponding to a force of the bit (10) over a respective increment of the distance between the initial and terminal points. Electrical incremental distance signals (14) are also generated, each corresponding to the length of the increment for a respective one of the incremental actual force signals (18). The incremental actual force signals and incremental distance signals are processed to produce a value corresponding to the total work done by the bit in drilling from the initial point to the terminal point. Using such a work assay, a number of other downhole occurrences and/or conditions can be assayed.

Title: Fabrication of embedded DRAMs
Inventor: LIOU FU TAI
IPC: H01L21/8242
Filed: 1998-10-16
Abstract: A method of manufacturing embedded DRAM capable of integrating memory circuit regions 101 and logic circuit regions 102 together such that their top surfaces are at the same height, and hence able to maintain a high degree of planarity in integrated circuits. The method includes depositing a layer of refractory metal oxide 116 over a high aspect ratio contact hole 112, 113, 114. Then, through the selective application of a hydrogen plasma treatment or hot hydrogen treatment, a portion of the deposited refractory metal oxide 116 on the contact hole is transformed from non-conductive to conductive material, whereas the refractory metal oxide without a hydrogen plasma treatment of hot hydrogen treatment remains non-conductive. Therefore, a non-conductive refractory metal oxide layer can be used as a dielectric layer for a DRAM capacitor 120.

Abstract: In order to supply to the transducer <B>T</B><SB>DH</SB> a time varying current of constant direction, the transducer is connected via a switching means <B>Q</B><SB>1</SB>, preferably a transistor, across a DC power supply, a capacitor <B>C</B><SB>1</SB> being effectively connected in parallel with the transducer creating an LC circuit in which the inductance is contributed by the transducer inductance <B>L</B><SB>L</SB> wholly or in combination with matching inductance <B>L</B><SB>H</SB>. A control signal controls the switching means such that it opens periodically at the drive frequency required by the transducer, and may be provided by means of a transformer <B>T</B><SB>X2</SB> whose primary <B>L</B><SB>E</SB> is connected to the LC circuit and whose secondary <B>L</B><SB>F</SB> is led to the transistor input. The circuit achieves "zero-crossing": substantial current passes through the switching means only when substantially no voltage is present across it, whereby heat loss in the switching means is minimised.

Title: A thermal recording element
Inventor: CHEN HUIJUAN DIANA
IPC: B41M5/26
Filed: 1999-06-15
Abstract: A thermal recording element which comprises a support having thereon an opaque recording layer which comprises hollow spherical beads dispersed in a hydrophilic binder (eg gelatin or PVA) the beads having a mean diameter of 0.2 Ám to 1.5 Ám and a void volume of 40% to 90%. The recording element appears opaque when coated because of the nature of the physical structure of the recording layer, which contains voids filled with air (inside the hollow beads). On applying heat and pressure eg. by a thermal printhead, to the element, the hollow beads soften, coalesce and release the air into the voids. The resulting recording layer then becomes transparent and reveals the colour of the underlying support generating a continuous tone, monochrome image. A process of forming a single colour image from the same recording element is also disclosed.
