Title: Assay reagents and devices
Inventor: PENFOLD YVONNE ELIZABETH
IPC: G01N33/532
Filed: 1997-09-10
Granted: 2008-11-18
Abstract: A reagent useful in immunoassays, comprising a direct particulate level co-sensitised with a specific binding agent having specificity for an analyte or analyte analogue and with a non-specific protein which can participate in a control reaction with another specific binding agent which does not bind to the first specific binding agent nor participate in the formation of a complex by means of which detection of the analyte or analyte analogue is accomplished. Preferably the first specific binding agent is an antibody raised in a first species and the non-specific protein is an immunoglobulin from another species. Optionally, the reagent additionally comprises a second population of the direct particulate label sensitised solely with the non-specific protein.

Abstract: A method and apparatus for measuring the depth of fluid in a well and for controlling the speed of a pump which pumps fluid out of the well according to the measured depth is disclosed. The depth of fluid in a well is measured by sending an acoustic pulse into an annulus between the well casing and the production tubing and sensing reflections of the acoustic pulse from collars on the tubing and a reflection from the fluid surface. Since the collar spacing on the production tubing is known, the distance from the top of the well to the surface of the fluid can be obtained by accumulating the distance associated with the collars detected in the reflection signal. The collar reflections are sensed by converting the reflected acoustic wave into electrical signals and then amplitude demodulating the broadband electrical signals. Once the distance from the top of the well to the surface of the fluid is determined, the height of the fluid above the pump inlet can be obtained by subtracting the distance from the top of the well to the surface of the fluid from the known distance from the top of the well to the pump inlet. The speed of the pump, and therefore its pumping capacity, is controlled according to the height of the fluid above the pump inlet.

Abstract: A frequency tracking loop for a communication system using orthogonal Walsh modulation is provided. The frequency tracking loop includes a correlator (120) such as a fast Hadamard transformation device, and a discriminator (130). The correlator (120) produces a correlation vector (122) representing the result of correlating the input signal with each of a set of Walsh functions, with corresponding index values. The discriminator (130) produces a frequency error signal (ê) based on the correlator (120) output with the highest energy level and other correlator outputs whose indices are related to the index of highest energy correlator output by powers of two. The frequency error signal (ê) is generated by producing a cross product between the highest energy output and one or more of the other related correlator outputs. In further aspects, a filter (140) can be used to further shape the resulting error signal (ê) and form a frequency offset estimate signal (~).

Abstract: Selon l'invention, des interfaces de changement d'heure (108) assurent le traitement d'informations dépendantes de la date au format à deux chiffres, les dates appartenant à un ou deux siècles. Ces interfaces de changement d'heure (108) convertissent des données de dates, contenues dans un fichier de données externe (114), d'heure locale en heure de zone, dans des fichiers d'entrées de zone (104), de sorte que toutes les dates soient incluses dans un siècle. Des programmes d'application (106) traitent les dossiers d'entrées de zone (104) au moyen de l'heure de zone au lieu de les traiter au moyen de l'heure locale. Après traitement, l'heure de zone contenue dans des fichiers de sorties de zone (113, 111) est traitée par les interfaces de changement d'heure (110, 109) de façon à produire des données de sortie en heure locale (112, 115). Avec ce nouveau procédé, les changements de programmation du format de date à deux chiffres à apporter aux programmes d'application (106) en raison du problème lié au changement de siècle sont minimisés ou éliminés.

Abstract: The invention generally relates to a reduced-fat cheese product and a method for producing such product. More specifically, this invention relates to reduced-fat, low-fat or fat-free natural shredded cheese products that do not exhibit the characteristics of stickiness and rapid skin formation upon melting which are normally associated with such cheeses. The cheese product of the invention, which has very low levels of fat, provides the taste and mouthfeel associated with full-fat cheeses. The fat content of shredded cheese is minimized by first producing an essentially fat-free natural cheese product and then applying a small amount of fat to the surface of the cheese in its shredded form. The amount of fat added can be controlled according to whether a reduced-fat, low-fat, or fat-free cheese is desired.

Title: Method for admitting new connections based on usage priorities in a multiple access system for communications networks
Inventor: CHUAH MOOI CHOO
IPC: H04L12/56
Filed: 1998-10-08
Granted: 2002-07-23
Abstract: In a method for controlling admission of remote hosts to a base station in a wireless communications network based on usage priority, there are at least two user priority classes and the base station admits a threshold number of remote hosts of the lower priority class and a maximum total number of remote hosts. When a base station receives a connection request from a new user of the higher priority class, if the current total number of admitted users is less than the maximum allowable, the new user of class is admitted, otherwise, the base station checks to see if any lower priority class users are currently admitted and allow disconnection. If so, the base station disconnect the lower priority user and admits the new user. In one embodiment, the base station disconnects the "least recently used" admitted lower priority user that allows disconnection. If it is appropriate to disconnect lower priority users after they are admitted, then lower priority users are admitted as long as the total number of associated users is less than the maximum allowable admittedusers. If it is inappropriate to disconnect lower priority users after they are admitted, then lower priority users are admitted only if the number of admitted users is less than the maximum number of total admitted users and the number of lower priority admitted users is less than the maximum allowable admitted number. This approachcan be extended to multiple priority classes. In an alternate embodiment, lower priority class users are admitted if the total number of currently associated users of all classes is less than a second threshold, normally lower than the threshold for higher priority users, rather than being based partially (as a second threshold) on the number of currently associated users of that lower priority class.

Abstract: An ATM cell constructor limits transmission-delay variations between successive cells of traffic of individual narrowband and wideband channels in a multi-channel environment. Whenever an ATM AAL1 layer of processing completes assembling an ATM cell payload for a narrowband channel, it increments a count that anticipates the number of ATM cells that will mature for transmission during the next cell construction period. For wideband channels, a function checks whether traffic from the number of narrowband channels that form the wideband channel will result in completion of assembly of that channel's cell payload during the next cell construction period; if so, the function increments the abovementioned count. The count is reset at the beginning of each cell construction period. Upon receipt of a command to add (start processing) a new channel, a TSI controller compares the count against a threshold that equals the total number of presently-active channels divided by the number of octets of traffic carried by each cell, plus one. If the threshold exceeds the count, the TSI controller sets up a TSI to start processing the new channel; otherwise the TSI controller delays setting up the TSI to process the new channel until occurrence of a cell construction period when the threshold exceeds the count. The net effect is to shift the delay variations from cells of active channels to the start-up of processing of new channels.
