Title: Direct vectored legacy instruction set emulsion
Inventor: HOERIG TIMOTHY R
IPC: G06F9/318
Filed: 1998-12-18
Abstract: A method and apparatus for emulating instructions of one microprocessor ("legacy instructions") with instructions of another microprocessor with an incompatible instruction set which provides increased throughput relative to known emulation systems. In particular, the legacy instructions are translated into direct vectors to software routines for each legacy instruction. Rather than fetching the legacy instruction and interpreting the instruction in software, the emulation system and method in accordance with the present invention fetches the direct vectors to the software routines which emulate the legacy instructions. The legacy instructions can either be translated by way of software when the legacy memory is loaded or modified, or by way of hardware when legacy memory is accessed. By fetching the direct vectors, the need for software-based look-up tables for interpreting the legacy instructions is obviated.      As such, the probability of cache misses is greatly reduced which increases the throughput of the system.

IPC: F16F9/32
Filed: 1998-06-25
Abstract: A lightweight low cost damping assembly having a piston rod on which a piston is formed such that fastener elements are not needed to secure the piston onto the piston rod. Preferably, the piston rod is formed by chrome plating the exterior of a tubular steel rod except at a piston attachment portion. The piston attachment portion is specially shaped such that the piston may be formed threon and coupled thereto by the inter-engaging of the piston with the shape of the piston attachment portion. Most preferably, the piston attachment portion is in the form of shallow grooves, knurls or dimples in the exterior of the piston rod and the piston is injection molded thereon. The material of the piston molds itself into the shape of the piston attachment portion, thereby resulting in a secure coupling between the piston and the piston rod.

Title: Database system for cross-marketing utilizing electronic coupons
Inventor: NICHOLSON G RANDY
IPC: G06Q30/02
Filed: 1999-03-25
Abstract: A system for providing multiple level, price-per-unit (PPU) discounts on gasoline to a customer who purchases at least one cross-marketed product. A point of sale (POS) terminal awards the customer a first PPU discount on the gasoline based on a purchase by the customer of a first cross-marketed product, and awards the customer a second PPU discount based on the purchase of a second cross-marketed product. A database controller then adds the first discount to the second discount to determine a total PPU discount, and the POS terminal prints a paper receipt for the customer with a customer identification and a transaction identification encoded in a bar code thereon. The total discount is stored in a discounts issued database. The customer then scans the encoded bar code with a bar code scanner at a gasoline dispenser to redeem the discount. The database controller retrieves the total discount from the discounts issued database, and the gasoline station then reduces the price-per-unit-volume of the gasoline by an amount equal to the total discount.      When the customer completes the gasoline purchase, a value of the total discount redeemed is determined and stored in a discounts redeemed database. A clearing house then allocates portions of the discount redeemed to vendors of the first and second cross-marketed products according to predetermined criteria.

Title: Method and apparatus for recovering a gas from a gas mixture
Inventor: YAMAMOTO TAKAO
IPC: C01B3/50
Filed: 1999-07-19
Abstract: An object of the present invention is to provide a method for recovering a gas using a semipermeable membrane in an apparatus having a simple structure.      The method is capable of maintaining a purity of a product gas at a constant value even if a feed amount of a feed stream is fluctuated. A feed stream G1 is a gas mixture of a fast gas having a relatively high permeability to a membrane 1 and a slow gas having a relatively low permeability to the membrane 1. The feed stream G1 is pressurized by a compressor 3 and fed to a membrane 1 separation unit 2 having the membrane 1.      Part G7 of the permeate stream on the permeate side of the membrane 1 is recirculated to the upstream side of the compressor 3 through the first recirculation line 17 and merged into a stream of the feed stream G1.      Simultaneously, another part of the permeate stream G2 on the permeate side of the membrane 1 is recovered through a product gas recovering line 5. In this manner, a product gas G3 having a fast gas increased in concentration is obtained.

Abstract: Novel sensor devices composed of a crystalline colloidal array (CCA) polymerized in a hydrogel are disclosed. The hydrogels are characterized as being capable of shrinking and swelling in response to specific stimuli applied thereto. As the hydrogels shrink or swell, the lattice structure of the CCA embedded therein changes, thereby changing the wavelength of light diffracted by the CCA. Thus by monitoring the change in diffracted wavelength, the concentration of a stimulus is determined. The gels can be modified to sense numerous different stimuli. The sensor devices are specific in that they are modified to react with only one species or family of species. These sensors have various applications in areas including, for example, environmental and chemical systems, chemomechanical systems, sensor devices and medical diagnostic tools. Various methods for making and using these devices are also disclosed.
