Title: Content addressable memory (cam) engine
Inventor: MELCHIOR TIMOTHY A
IPC: G06F17/30
Filed: 1998-11-13
Granted: 2010-01-12
Abstract: A content addressable memory ("CAM") engine (100) or controller interfaces between a host signal processor (e.g., a microprocessor) and a plurality of known, commercially-available random access memory ("RAM" ) devices. The CAM engine (100) configures the RAM as content addressable memory, thereby causing the normally location-address d RAM to function as CAM. The CAM engine (100) thus allows for the benefits of both RAM and CAM devices, such as speed, density, cost and intuitiveness, without their inherent drawbacks. Further, the CAM engine (100) implements various flexible memory storage configurations for the keys and associations stored in RAM. Also, the CAM engine (100) implements certain algorithms that provide for th e hashing of data, for table load and unload capabilities, for proximity matching, for dealing with overflow conditions, and for implementi ng hierarchical search capabilities.

Patent CA-2324220-C (CA)
Inventor: APPIUS RAPHAEL
IPC: G01C15/00
Filed: 1999-03-22
Granted: 2007-09-18
Abstract: The invention relates to a method for determining the spatial and rotational positions of an object (1). With the assistance of an imaging optical system (5), the object (1) is mapped and detected on a high- sensitivity resolution optoelectronic detector (7). The location parameter of the object (1), such as the position vector (r~), the direction vector (~) of the object axis (4), and the angle (~) of rotation of the object (1) around the object axis (4) is determined from the planar position of the mapped object structures (2a; 2b) in the coordinate system (X Det, Y Det) of the detector (7) by means of geometric optical relationships and mathematical evaluation methods. With this, the spatial position of the object (1) is determined in a quick and contactless manner.
Patent CA-2329286-C (CA)
Inventor: HIDDING DOUGLAS J
IPC: B65D41/34
Filed: 2000-12-20
Granted: 2008-06-10
Abstract: An improved tamper resistant bottle cap and neck for bottles which hold liquid. The bottle cap of the present invention includes a circular cover, a skirt depending from the periphery of the cover, and a tamper evidencing lower portion. A raised ring formed on the outer and upper surface of the bumper roll typically used in blow-molded containers protects the lower edge of the cap from tampering by making the lower edge of the ratchet ring in the case of a thread-on cap (or the lower edge of the removable portion of a skirt in the case of a push-on cap) less accessible to potential tamperers. Thread-on caps with helical threads and a ratchet ring, or push-on caps with skirts having removable lower portions, may each be equipped with an arched or curved pull tab. The pull tab in each instance is designed to accommodate a raised ring on the bumper roll of the neck of a blow-molded bottle. By designing the pull tab to accommodate the raised ring on the bumper roll the presence of the ring does not induce unwanted stresses and deformations into the pull tab or the skirt or ratchet ring to which the pull tab is connected.

Abstract: A weight is attached to the rear side of a magnetic circuit of a speaker unit. The tip of a boss that projects to the front side from the weight is joined to the rear side of a center pole of the magnetic circuit with a bolt. Even if reactive force that is generated when an electrical signal is converted into mechanical vibration by the magnetic circuit and a voice coil and sound waves are emitted from a vibration plate is transmitted to the magnetic circuit, the vibration of the magnetic circuit is suppressed by the weight. In this manner, sound quality with a good transient characteristic can be obtained.

Title: Technique for facilitating the pumping of fluids by lowering fluid viscosity
Inventor: NARVAEZ DIEGO
IPC: E21B28/00
Filed: 2002-06-13
Granted: 2005-11-22
Abstract: A viscosity handling system for facilitating the movement of certain fluids.  The system utilizes kinetic energy in the form of a rapidly and repetitively moving component that imparts energy in the form of heat to surrounding fluid. The system is particularly useful in applications, such as downhole pumping systems, used to produce hydrocarbon-based fluids from beneath the surface of the earth. The viscosity handler lowers the viscosity of the fluid produced to permit greater flow rates and more efficient utilization of production pumps.
