Title: A method of incorporating independent feedforward control in a multivariable predictive controller
Inventor: LU ZHUXIN J
IPC: G05B11/36
Filed: 1996-06-14
Abstract: A process control system includes a feedback controller and has at least one manipulated variable and one controlled variable. A feedforward loop is included, the system being subject to a disturbance.  Independent feedforward control is incorporated into the feedback controller which comprises the following steps. A feedforward control funnel and a feedback control funnel are defined for each cv, specifying a time T FF in which the disturbance is to be eliminated and a time T FB in which the controlled variable is to reach a steady state value, respectively. The shorter of the feedforward control funnel and the feedback control funnel is selected. If T FF is less than T FB, the feedback control speed is compensated such that the feedback controller speed is not increased. If T FF is greater than or equal to T FB, no compensation is performed, thereby effectively providing independent tuning parameters for the feedforward control solution and the feedback control solution. New values of the cvs are calculated and the process controlled by the newly calculated cvs.

Title: Method of encoding and signal processing to extend range of transmission over repeaterless two-wire telephone line
Inventor: BURCH RICHARD A
IPC: H04L25/49
Filed: 1996-08-16
Abstract: The range of digital data communication services, such as a basic rate 2B1Q  ISDN channel, to customer premises located beyond the industry standard achievable range of a two-wire loop can be extended by increasing the capacity of the ISDN line code from two information bits per symbol to three information bits per symbol, so as to reduce the effective symbol rate, which is error correction encoded to an effective 4B1H line code for defining a sixteen level PAM signal waveform, and employing enhanced low signal-to-noise ratio signal processing techniques in both the transmitter and receiver to accommodate the increased insertion loss of the two-wire line resulting from its extended length. Such enhanced low signal-to-noise ratio signal processing techniques include a Tomlinson precoder (25) in the transmitter, and an adaptive linear equalizer (53) and a module unit (55) in the receiver.

Abstract: The invention relates to compositions for cleaning hard surfaces, wherein said composition comprises both cleans the surface and prevents or retards further soiling of the surface and provides an aqueous, hard-surface cleaning composition comprising a surfactant mixture, wherein said surfactant mixture comprises:   a)   a cationic fluorosurfactant, and, b)   a non-fluorinated nonionic surfactant.            It is believed that the cationic fluorosurfactants present in the compositions of the present invention modify the surface energy of surfaces to which the composition is applied so as to raise the contact angle of soil subsequently deposited on the modified surface. Suitable fluorosurfactant compounds can be broadly described as compounds which contain at least one CF3 moiety and a group carrying a positive charge. Preferably, the fluorosurfactants employed in the present invention are of the general formula:       (I)  CF3-L-N+R1R2R3 wherein L is a linking group which is preferably selected from linear or branched aliphatic or fluoro-aliphatic chains which may contain heteroatoms and R1, R2, and R3 are preferably short chain alkyl groups, typically C1-C5 alkyl groups of which methyl groups are preferred: in an alternative, one of R1, R2 or R3 is itself a moiety of the form CF3-L-.

Abstract: A filter co-processor (103, 109 and 109 fig.) within a Digital Signal Processor (DSP) takes advantage of the orthogonal nature of modulated signals during the equalization process. Since, after reception, only certain real/imaginary values of the received signals (112) are useful for demodulation, the filter co-processor only processes those values to estimate the transmitted signal. By processing only those values for demodulation, the filter co-processor is able to process information in a given amount of time, leading to increased processing when compared to the prior art.

IPC: G01N27/447
Filed: 1996-12-12
Abstract: Gel holders for electrophoresis gels are made using fibers, particularly glass fibers, which are affixed to the substrates forming the gel holder using an adhesive. These gel holders can be made by placing a plurality of adhesivecoated fibers between a first planar substrate and a second planar substrate; and applying pressure to the outside of the substrates to adhere the fibers to the first and second substrates. This forms a gel chamber between the first and second substrates which has a thickness defined by diameter of the fibers. Alternatively, uncoated fibers may be laid down in pairs, with a line of adhesive disposed between each fiber of the pair. When the adhesive is cured, it binds the fibers in position as spacers. At the same time, the fibers isolate the adhesive from the gel compartment. In this way, interference of components of the adhesive with the polymerization of the gel in the gel chamber can be avoided. Gel holders formed using either of these methods may be filled immediately with a gel forming solution such as a polyacrylamide, or they may be stored indefinitely and used as needed.

Abstract: A counterweight assembly is provided to add weight over the steering wheels of a vehicle such as a front mount tractor when it is used on inclines or with heavy implements. The assembly includes a support bracket that is removably mountable on the rear of the vehicle frame adjacent the steering wheels. Receivable on the support are a plurality of counterweights and a hitch extension plate. The assembly is mounted within the turning circle of the vehicle and the counterweights are triangularly shaped to contain them within the turning circle as well. When used with a vehicle having the operator station facing away from the assembly, its containment within the turning circle serves to minimize the likelihood that it will make inadvertent contact with objects adjacent the work area of the vehicle.

Abstract: Disclosed is a method for producing cellulose derivatives wherein cellulose is impregnated with an alkali solution, the impregnated cellulose is selectably pressed out, and the cellulose undergoes a substitution or addition reaction, whereby the cellulose derivative is obtained with a degree of substitution DS.  The applied cellulose is an ammonia activated cellulose. The molar ratio of the alkali to the AHG (anhydro glucose unit) in the cellulose at the beginning of the substitution or addition reaction does not exceed twice the valve of the desired DS. For the swelling of cellulose, no excess of alkali is required, which does not react to produce alkali cellulose but only adheres to the cellulose as a loose association product. Reagent consumption in the substitution or addition reaction is lower. Fewer secondary products are formed.

Abstract: An arc fault detector turns on an electronic switch connecting a power distribution cable to ground thereby actuating a cable limiter to isolate the power distribution cable in response to an arc fault even though the arc fault itself does not create a low enough impedance fault to actuate the cable limiter directly. The electronic switch can be a sacrificial low cost silicon controlled rectifier which is destroyed by the ground fault it creates as long as the let-through current of the cable limiter is below the explosion current of the SCR.  A single arc fault detector and SCR which fails as a short circuit can be used to actuate cable limiters at both ends of a short power distribution cable fed at both ends, or preferably separate protection can be provided adjacent both cable limiters.

Title: Method and apparatus for covariance matrix estimation in a weighted least-squares location solution
Inventor: JONES DEBRA A
IPC: G01C21/20
Filed: 1997-12-19
Abstract: Signals exchanged between a fixed infrastructure (110-116) and a mobile unit (160) give rise to M channel quality metrics. The channel quality metrics are mapped, via predetermined relationships (501-503), into M corresponding time of arrival variances, which in turn are used to derive M-1 time of arrival differential variances. A time of arrival differential weighting matrix including, in part, the time of arrival differential variances, is used to calculate a WLS solution, which solution is an estimate of a location of the mobile unit. This procedure may be implemented using an infrastructure-based location processor (130) operating in conjunction with the mobile unit, or may be performed by either the location processor or mobile unit alone.
