Patent number: 6268161Abstract: A biosensor (10) has a pH-sensitive polymeric hydrogel (30) in a rigid and preferably biocompatible enclosure (20). The hydrogel (30) includes an immobilized oxidoreductase enzyme such as glucose oxidase. The oxidoreductase enzyme catalyzes a chemical reaction consuming an organic molecule and producing a byproduct. The hydrogel (30) changes its osmotic pressure in proportion to the concentration of a byproduct. By measuring the change in osmotic pressure with a pressure transducer (40), the biosensor (10) is able to accurately measure the concentration of the organic molecule without the problem of interference encountered by prior art biosensors. A battery (64) powered telemeter (60) operably engaged to the pressure transducer (40) sends a radio data signal to a receiver (66) operably attached to a computer (62).Type: GrantFiled: May 11, 1999Date of Patent: July 31, 2001Assignee: M-Biotech, Inc.Inventors: In Suk Han, You Han Bae, Jules J.

Patent number: 6262553Abstract: The present invention is a control system for a vehicle that utilizes a powered attachment such as a material spreader. Such a device requires the use of a high current drawing motor, which in turn requires the ability to control the flow of high amperage current. The high current switching circuitry is mounted on or near the electric motor to prevent the heat generated by the circuitry from posing any type of hazard. A low current control is placed within the cab of the vehicle and serves to remotely control the switching circuitry.Type: GrantFiled: April 13, 1999Date of Patent: July 17, 2001Assignee: M. P.

Patent number: 6260409Abstract: Methods are described for measurement and prediction of site specific scour around a structure obstructing a flow. Representative soil samples are collected from an area proximate the structure location and tests are conducted on the samples to determine the erosion rate and hydraulic shear stress imposed. The maximum shear stress and initial scour rates around the structure are also obtained. Next, the maximum depth of scour is calculated, and the depth of scour versus time curve for the structure is then predicted. In a preferred embodiment, the methods described are used to predict a scour depth versus time curve around a cylindrical bridge support standing in the way of a constant velocity flow and founded in a uniform cohesive soil. An erosion function apparatus is also described which can be used to test representative samples of soil in the area where a structure is located.Type: GrantFiled: March 11, 1999Date of Patent: July 17, 2001Assignee: The Texas A&M University SystemInventors: Jean-Louis C.

Patent number: 6263211Abstract: A system and method in a radio telecommunications network for automatically conveying a Wireless Office System (WOS) frequency set to a mobile station (MS) belonging to the WOS. The network includes a public cell, and a private WOS located within the public cell. A WOS controller sends the WOS frequency set from the WOS to an Equipment Identity Register (EIR) in the network whenever the WOS changes its frequency set. When the MS registers in the public cell in which the WOS is located, a mobile switching center (MSC) serving the public cell notifies an Intelligent Roaming Database (IRDB) of the registration. The IRDB fetches the WOS frequency set from the database, and obtains location information for the MS from a home location register (HLR). The IRDB then sends the WOS frequency set to the MS in an IS-136 R-DATA message.Type: GrantFiled: September 24, 1998Date of Patent: July 17, 2001Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Richard Brunner, Akbar Rahman

Patent number: 6259724Abstract: A mobile communications system is provided for significantly reducing the time required to process a random access mobile-originated call. During call setup, a mobile station transmits a random access packet that includes a preamble and a plurality of fields. The information provided in these fields is used by the base station to facilitate a more efficient call setup and more quickly allocate channel resources. A system is also provided for detecting, identifying and receiving multiple random access requests. Each mobile station transmits one of a plurality of different preamble symbol patterns in a random access request packet. The base station receiver includes a plurality of accumulators, each of which is tuned to a different preamble symbol pattern. Consequently, the base station receiver can distinguish between simultaneous random access requests.Type: GrantFiled: October 18, 1996Date of Patent: July 10, 2001Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventor: Riaz Esmailzadeh
