Abstract: L'invention porte sur un procédé de réponse à une demande de ressources issue d'un noeud d'utilisateur de demande dans un réseau de noeuds d'utilisateur. Selon le procédé, une réponse à la demande de ressources est reçues au niveau d'un premier noeud d'utilisateur du réseau, et il est déterminé (par exemple au hasard) s'il faut oui ou non renvoyer la réponse vers le noeud d'utilisateur de demande. Lorsqu'il est déterminé de ne pas envoyer la réponse au noeud d'utilisateur de demande, la réponse est transmise au second noeud d'utilisateur du réseau par connexion directe. Lorsqu'il est déterminé d'envoyer la réponse au noeud d'utilisateur de demande, la réponse est renvoyée au noeud d'utilisateur de demande. L'invention concerne aussi un noeud d'utilisateur qui s'utilise dans un réseau informatique équipé de noeuds d'utilisateur qui sont chacun reliés aux autres noeuds d'utilisateur par connexions directes.

Title: Method for producing heating radiating boards (variants)
Inventor: GOLOVENKOV ALEXEI VITALIEVICH
IPC: F24D13/02
Filed: 2001-07-26
Abstract: The inventive method for producing heating radiating boards relates to electrothermics and can be used for heating housings and working areas and f or industrial purposes for drying wood, sand and grain. Said method is carried out as follows: a substrate (1) is pre-cleaned, washed, degreased, dried and a conductive coating (2) is applied thereto. The composition of the conductive coating is pre- filtered and applied to the dielectric substrate (1), using a known method, for example spraying or dipping, and dried. When necessary, th e application of the composition to the dielectric substrate and the drying thereof are repeated several times. Afterwards, an additional conductive coating in the form of stripes (3) is formed. The stripes (3) can have different configuration in relation to the required thermal field of the heating radiating board. A protective layer 4 is applied to the conductive coating (2) and the additional conductive coating (3).

Title: Mutants of green fluorescent protein
Inventor: STUBBS SIMON LAWRENCE JOHN
IPC: C07K19/00
Filed: 2001-09-28
Abstract: The present invention provides novel engineered derivatives of green fluorescent protein (GFP) which have an amino acid sequence which is modifie d by amino acid substitution compared with the amino acid sequence of wild typ e Green Fluorescent Protein. The modified GFPs exhibit enhanced fluorescence relative to wtGFP when expressed in non-homologous cells at temperatures abo ve 30 ~C, and when excited at about 490 nm compared to the parent proteins, i.e . wtGFP. An example of a preferred protein is F64L-S175G-E222G-GFP. The modifi ed GFPs provide a means for detecting GFP reporters in mammalian cells at lower levels of expression and/or increased sensitivity relative to wtGFP. This greatly improves the usefulness of fluorescent proteins in studying cellular functions in living cells.

Title: Electrochemically textured surface having controlled peak characteristics and the method of manufacture
Inventor: LASIA ANDRZEJ
IPC: C25D5/18
Filed: 2001-07-05
Abstract: Textured surfaces comprised of peaks which have been electrochemically deposited on a substrate are prepared using a pulsed direct current process.  Typical substrates are machine components such as a machine roll.

Inventor: WELSH THOMAS R
IPC: H02N2/00
Filed: 2002-07-15
Abstract: Systems and circuits embodying the invention include means for sensing at least one of the peaks, amplitude and frequency of an oscillatory input forc e impinging on a power generating device (22) for controlling the turn-on of a switch used to transfer energy collected by the power generating device to a n associated load. The power generator may be a transducer such as a piezoelectric device or a wave energy converter (WEC). Sensors and sensing means embodying the invention are used to control the point in time at which power extracting circuits are switched in circuit with the power generating device. The power extracting circuit may include components which can resona te with the power generating circuit at a higher frequency than, and independen t of, the frequency at which the power generating device is being operated. Thus, an electric power generator device operated and controlled by a slowly changing source of energy (e.g., ocean waves, wind, eddies of water) may develop energy at one frequency and may be operated to transfer the energy, at a selected point in time, at another frequency.

Abstract: A system contains a laser output measurement circuit used in a laser control system (210). The circuits contain a photodiode sensor (109), sample and hold amplifier (202), IC with synchronizer and delay circuits (206), and an analog to digital converter (204). The circuits measure the laser light output (107) while the laser Module (106) transmits signals. The measurement circuit tracks and stores the laser light output (107) signal using a Photodiode Sensor (109) and with a Sample/hold (202). The methods calculate the value of the laser light output (107) from mathematical relationships, which correlate the light output (107) of the laser Module (106) to the current value of the drive signal (100). Some of the distinguishing features in the present invention are 1) feedback information from the photodiode is obtained in a synchronous manner as a snapshot of the laser performance, and 2) the measurements are precise and calibrated, and 3) no disruption of the signal transmission occurs.

Title: Adaptive control architecture for electric machines
Inventor: MASLOV BORIS A
IPC: H02P25/08
Filed: 2003-03-28
Abstract: An adaptive architecture for electric motors, generators and other electric machines. An adaptive electric machine provides optimal performance by dynamically adapting its controls to changes in user inputs, machine operating conditions and machine operating parameters. Isolating the machine's electromagnetic circuits allows effective control of more independent machine parameters, that enable greater freedom to optimize and provide adaptive motors and generators that are cheaper, smaller, lighter, more powerful, and more efficient than conventional designs. An electric vehicle with in-wheel adaptive motors enables delivery of higher power with lower unsprung mass, giving better torque-density. The motor control system can adapt to the vehicle's operating conditions, - such as including starting, accelerating, turning, braking, and cruising at high speeds, - thereby consistently providing higher efficiency. A wind powered adaptive generator can adapt to changing wind conditions, consistently providing optimal performance. An adaptive architecture improves performance in a wide variety of electric machine applications, particularly those requiring optimal efficiency over a range of operating conditions.
