Title: Capteur electrochimique pour l'analyse d'echantillons liquides
Inventor: STEWART ALAN ANDREW
IPC: C12Q1/00
Filed: 2000-04-28
Abstract: L'invention concerne une cellule électrochimique possédant une zone auxiliaire contenant une espèce redox sur une électrode de travail. Cette zone constitue une voie de faible résistance pour le courant, entre ladite électrode et une pseudo-électrode commune faisant office de référence et de compteur. La zone auxiliaire fait partie intégrante de l'électrode de travail et assure un flux de courant accru. Ce courant accru s'ajoute au signal de mesure, ce qui réduit la chute de courant non monotone qui peut conduire à des mesures de l'analyte erronées.

Abstract: ABSTRACT   A method, system and apparatus for scheduling data to subscriber stations from a base station over a shared channel. Data destined for each subscriber station is placed into queues at the base station. The base station allocates a portion of the shared channel to each particular queue based upon that queue's priority value. The priority value for each queue is determined by an adjusted QoS value and an adjusted throughput value. The QoS value indicates whether a subscriber station has been receiving data according to an agreed-upon QoS  level. The throughput value indicates the data rate that can be achieved by transmitting to that subscriber station. These two values are examined by a scheduling policy at the base station. Scheduling policies can include scheduling data to emphasize fairness between subscriber stations, scheduling data to improve overall throughput, and scheduling data to achieve a balance between fairness and throughput.

Abstract: A packaging device is provided for monitoring use of packaged contents using analog methodology. The packaging device comprises a package, an electrically conducting path and a central processing unit (CPU) with associated analog-to-digital converter embedded in the package. The package has one or more sealable receptacles for accommodating contents. The electrically conducting path is associated with each receptacle in such a way that the receptacles and their associated paths comprise either resistances in parallel or resistances in series within the circuit. Opening the sealed receptacle and expelling its content causes changes in the electrical characteristics of the circuit. The central processing unit (CPU) and its analog-to-digital converter monitor the electrical characteristics of the conducting path for changes, and generate content use data when changes in the electrical characteristics of the circuit are detected.

Abstract: The present invention provides compositions, methods, and kits for covalently linking nucleic acid molecules. The methods include a strand invasion step, and the compositions and kits are useful for performing such methods. For example, a method of covalently linking double stranded (ds) nucleic acid molecules can include contacting a first ds nucleic acid molecule, which has a topoisomerase linked to a 3' terminus of one end and has a single stranded 5' overhang at the same end, with a second ds nucleic acid molecule having a blunt end , such that the 5' overhang can hybridize to a complementary squence of the blunt end of the second nucleic acid molecule, and the topoisomerase can covalently link the ds nucleic acid molecules. The methods are simpler and more efficient than previous methods for covalently linking nucleic acid sequences, and the compositions and kits facilitate practising the methods, including methods of directionally linking two or more ds nucleic acid molecules.
