Patent number: 6270117Abstract: A method for activating air bags in motor vehicles without the use of electrically powered deceleration sensors. This method utilizes the impact of one mass of quartz against another to generate a flash of visible light to initiate activation of the air bag system under conditions of extremely sudden deceleration. This flash of light, which is detected by a photo-sensitive element, initiates deployment of the air bag system without reliance on the electrical cables currently used for this purpose, but which could be damaged in the first moment of a collision, thus preventing inflation of the air bags. This substitution of a photo-sensitive activation system for a system dependent on electric cables substantially enhances the reliability of the air bag deployment concept.Type: GrantFiled: February 11, 2000Date of Patent: August 7, 2001Assignee: Delphi Technologies, Inc.Inventor: Edwin Charles Storey

Patent number: 5765201Abstract: When a computer system is upgraded, such as by adding a more advanced processor chip and/or a new operating system, a different page size may be employed. The page size is altered for data previously stored in a storage medium such as a hard disk in the computer system, without removing all of the data from the medium and rewriting it. Data is stored in the medium in blocks or sectors which have headers defining the block. Also, tables define memory objects and segments, and locate virtual memory addresses in physical memory. The headers and/or tables can be changed without rewriting all of the data in the sectors or pages in physical memory, so the page size is changed to accommodate the new system components, without excessive burden on system hardware or undue expenditure of time.Type: GrantFiled: July 31, 1995Date of Patent: June 9, 1998Assignee: International Business Machines CorporationInventors: Mark Gregory Manges, Lynn K.

Patent number: 5733070Abstract: A method of improving ground soil irrigation by employing an additive or amendment in the form of an improved synthetic solution grade calcium sulfate dihydrate composition. This composition is formulated by contacting a calcium compound having a calcium cation with a chemical agent enabling the calcium compound to yield calcium ions upon reaction with the chemical agent and which enables the calcium cation to react with an anion of the chemical agent forming a second calcium compound. The second calcium compound is reacted with a sulfur containing acid, such as sulfuric acid, to thereby form a calcium sulfate dihydrate. The compound has improved suspension characteristics and will remain in suspension for a much longer period of time than a conventional solution grade calcium sulfate dihydrate.Type: GrantFiled: January 6, 1997Date of Patent: March 31, 1998Inventor: Edwin Charles Angell

Patent number: 4122399Abstract: The problems of high cost, high loss and incomplete distortion compensation are resolved in a distortion generating circuit which employs a nonlinear phase modulator (70, FIG. 7) and a linear phase shifter (71) as a means of generating selected distortion signal components. The circuit includes an output coupler (30) and an output coupler (31) interconnected by means of a pair of wavepaths (32, 33). The nonlinear phase modulator (70), which includes a nonlinear reactive element (37), is disposed in one of the wavepaths (32). The linear phase shifter (71) is included in the other wavepath (33). By the appropriate adjustment of the linear phase shift in wavepath (33) the entire gamut of distortion characteristics can be compensated.
