Patent CA-2380189-A1 (CA)
Inventor: NAZAR LINDA
IPC: H01M4/86
Filed: 2002-04-03
Abstract: The increasing role of technology in our lives has necessitated the development of advanced energy storage technologies to power portable electronic devices such as cellphones, and laptops. With concern for the impact of emissions from gas engines on our environment rising, low emission vehicles that incorporate these devices are also now rapidly gaining consumer acceptance. Considered the most advanced of the available rechargeable technologies, lithium ion batteries rely on solid state intercalation compounds that are able to reversibly intercalate Li cations at both negative and positive electrodes. Both cell potential and capacity are governed by the electrode chemistry; namely its electronic and crystal structure. The main issues in improving the chemistry reside in a better understanding of the processes that occur in the bulk (and also on the surface) in addition to the development of new materials. This talk will focus on some recent new developments in both negative and positive electrode materials arising from solid state chemistry.

Inventor: RAVN PETER
IPC: C12N15/09
Filed: 2000-08-04
Abstract: L'invention concerne un procédé d'identification de séquences nucléotidiques codant pour des peptides signaux dans des bactéries d'acide lactique, qui utilise une molécule d'ADN contenant un transposon qui inclut un gène rapporteur sans promoteur ; une région de cette molécule d'ADN, située entre l'extrémité terminale gauche et le gène rapporteur, est délétée et la molécule d'ADN comporte une séquence d'ADN codant pour une molécule rapporteur de sécrétion. La délétion de la région située entre l'extrémité terminale gauche et le gène rapporteur permet d'éliminer les codons de terminaison situés dans le même cadre de lecture que la molécule rapporteur de sécrétion, ce qui, au cours d'une transposition, permet des fusions traductionnelles à partir d'une région située en aval de l'extrémité terminale gauche.

Inventor: WILKENFELD ARI
IPC: A61F2/38
Filed: 2001-03-29
Abstract: The invention relates to an automated speed-adaptive and patient-adaptive control scheme and system for a knee prosthesis (110). The control scheme and system utilizes sensory information measured local to the prosthesis (110) to automatically adjust stance and swing phase knee resistances to a particular wearer under a wide variety of locomotory activities. Advantageously, no patient-specific information needs to be pre-programmed into the prosthetic knee (110) by a prosthetist or the patient. The system (110) is able to adapt to various types of disturbances once the patient leaves the prosthetist's facility because it is patient-adaptive and speed-adaptive.
