Abstract: Apparatus for reducing the size of an object (41) disposed in a generally closed fluid medium includes a hand piece (63) having an axis extending from a housing (64) at a proximal end to a probe (65) at an opposing distal end. A reducer (179) at the distal end of the probe (65) is adapted < 1 M G > for insertion into the fluid medium (201) where it is rotatable to reduce in size the object (41). The reducer (179) is configured to create a fluid flow (202) in the fluid medium (201) so that the end piece (63) can be maintained laterally and axially stationary while the object (41) is moved (203) by the fluid flow (202) into contact with the reducer (179). An associated method includes the steps of rotating the rotary member (179) at a speed sufficient to reduce the size of the object (41), and in a manner to produce a flow (202) of the fluid (201) sufficient to move (203) the object (41) into the rotary member (179).

Title: A method for automatically displaying map symbols
Inventor: JOHNSON KENNETH R
IPC: G06T17/05
Filed: 1995-01-27
Granted: 2000-08-29
Abstract: A method for automatically displaying map symbology in a Geographic Information System. In the method, a computer (18) retrieves records (21, 22 and 23) from a data base (20) for each map feature that lies within the extent of the displayed portion (42) of the map (15). The records (22) for point features are organized in "flat" structures (48) where each map feature is represented by a single symbol (16), and in multi-level "hierarchical" structures (54) where each feature is represented by a hierarchy of symbols (16) representing different resolutions of the map features. For a hierarchical symbol structure, the level of records retrieved (62) by the computer is determined by the scale (44) of the map displayed to the screen (14). The computer determines (64), for each symbol (16) at the particular map scale (44), whether the symbol extensively overlaps any other symbol. The symbols that overlap significantly are modified (66) to reduce the clutter by either merging (98) the overlapping symbols into a single symbol including a numeric identifier or replacing (124) the symbol and its siblings by the single parent symbol in the hierarchy. The symbols (16) from the modified records (22) are displayed (70) to the screen (15).

Abstract: The  effectiveness  of  a  microstrip  conductor antenna,  such as  a patch antenna,  is  improved at  any particular  frequency  by  making  the  thickness  of  the conductor sufficiently small to reduce shielding and losses caused by the skin effect and make currents at the upper and lower surfaces couple with each other and make the conductor partially transparent to radiation.  In one embodiment the thickness is between 0.5? and 4?.  Preferably the thickness is between 1? and 2? where ? is equal to the distance at which current is reduced by 1/e.,  for example 1.5 to 3 micrometers at 2.5 gigahertz in copper.  According to an embodiment, alternate layers of dielectrics and radiation transparent  patches  on  a  substrate  enhance  antenna operation.

Abstract: The present invention is connected with a process for the formation of dental restorations from glass-ceramic materials and the resulting dental restorations. In this invention a dental restoration is prepared by placing a glass ceramic material in a heat-pressure deformable crucible. Heat is then applied to the crucible in order to bring glass-ceramic material to a working range at temperatures above its liquidus temperature. The heat deformation properties of the crucible must be such that when the glass-ceramic material in the crucible is in the working range the crucible is heat-pressure deformable without rupturing. Once the glass-ceramic material is heated to its working temperature the crucible is brought into contact with a mold having a preformed cavity therein, the cavity being in the shape of the desired dental restoration.  As the distance between the heated glass ceramic material and the mold is decreased, the crucible is deformed to form a seal with the mold thereby facilitating the injection of the molten glass-ceramic material into the mold cavity. The resulting dental restoration has superior optical esthetic and strength properties. The invention further includes the heat-pressure deformable crucible which is useful in the process of this invention and the related apparatus.

Abstract: In a method for making a fibrous product from separate particles, an air flow (A) is used for forming a mat on an advancing forming platform (1).  The particles are bonded to form the mat by means of thermally activatable binder material brought to the mat forming site such that it upon being activated through the action of heat bonds the particles to each other in the mat.  Said binder material is brought to an activated state already in air flow (A) carrying the particles onto forming platform (1) by setting temperature of the air flow sufficiently  high The material forming the base of the mat in the particles is constituted of a material activatable at a higher temperature than the thermally activatable binder material.

Title: Video compression using an iterative error data coding method
Inventor: ZHANG TAI Y
IPC: H04N7/26

Granted: 2007-02-13
Abstract: An adaptive system (10) and method for data storage and communication is primarily used for the storage and transmission of large volumes of data, especially video data, over band-limited communication channels. The video coder (200) of the system (10) uses a prediction video signal which is subtracted from the input image to define a processing region in which image blocks of predetermined dimensions have large prediction error. The prediction image is successively improved by iteratively processing large error image blocks until the error is reduced below a predetermined threshold. At different processing iterations and image blocks, different compression techniques can be used to improve the overall system efficiency.
