Abstract: Solanum stenotomum, Solanum phureja and Solanum goniocalyx, which are diploid potatoes native to the Andes, are crossed by open pollination, thereby forming a hybrid population rich in genetic variation. The hybrid population is raised while screening the hybrid population on the basis of selection criteria including a yield thereof, thereby reconstituting the hybrid population. The reconstituted hybrid population is raised for seedlings under short-day light conditions while limiting a rhizosphere thereof and controlling the growth at a slightly lower temperature during a potato-tuber growing period. A mini-potato edible whole (including skin) in one bite can be thus obtained.

Title: Communication system architecture and operating protocol therefor
Inventor: WRIGHT SARAH LUCY
IPC: H04Q11/04
Filed: 1998-12-15
Granted: 2007-01-23
Abstract: A connection broker (44), located between lower-level system entities (16, 58, 264) associated with a narrowband-broadband interface (250) and a call server (18) that controls call connection across the narrowband-broadband network, contains a memory (251) that stores connection-related information and protocol converters. The connection broker (44) accesses the protocol converters to interpret control messages received from the call server (18) and, where necessary, transposes messages for the call server into a standardised format for use over a uniform fabric application interface (66). Control messages pertaining to connection paths within the narrowband-broadband network (250) and relayed via the connection broker (44) are appropriately phrased (by the connection-related information and protocol converters) to ensure that meaningful information and instruction is communicated between the call server (18) and the lower-level system entities (16, 58, 264). Use of the protocol converters therefore enables connection attributes and network operation and configuration to be altered and advised in-call by having the connection broker (44) both change connection-related information and communicate any change in network configuration to the call server and lower-level system entities, as appropriate.

Abstract: An object of the invention is to provide excellent operability in receiving a textual message. A call set-up signal representing that a textual message from a transmitter side is transmitted, and a textual message are received by a transmission and reception circuit without performing any response to the incoming call, and the received textual message is stored in a memory. Notification means performs a notification operation by the call set-up signal being received.      The receiver can read the message by viewing display means.      Thus, the message from the transmitter can be received in real time. Since it is unnecessary to respond to an incoming call, the receiver side is not charged. An incoming call operation is performed by operating a response button, and speech processing can be performed by use of a microphone and a speaker.

Title: Dual mode ophthalmic laser ablation
Inventor: HOHLA KRISTIAN
IPC: A61B18/00
Filed: 1998-04-24
Granted: 2010-06-15
Abstract: A dual mode excimer laser eye surgery system is provided. The eye is first treated for primary corneal defects using a large, fixed spot size, and remaining irregularities are removed using a small fixed spot size. The large size allows for faster treatment, and the small size provided for more precision in the treatment of irregular topographies. The system is preferably implemented in a distributed topography environment. For example, a treatment pattern using a large, fixed spot size is provided to doctors based on visual acuity data, such as the degree of dioptric correction needed. The effect of this treatment is then overlaid on a computer against the patient's actual eye topography. The small fixed spot size is used to remove any remaining irregularities yielding a preferred treatment pattern. This combined treatment pattern is then distributed to an excimer laser eye surgery system that performs the large spot size ablation and then the small spot size ablation.

Abstract: A mechanism (1) for selectively securing a cover to a flange of a pressure vessel (15). The cover (14) and flange (12) each have openings that are aligned when the cover (14) is in position facing the flange (12). The mechanism (1) includes an anchor plate (18) having a hole therethrough. A piston (34) is slidable in a direction normal to the cover (14) in alignment with the opening therethrough. A stud (10) extends from to the piston (34) with a stud head (42) remote from the piston (34). The stud head (42) fits through the opening of the closer of the cover (14) and flange (12) and through a wider portion of the anchor plate (18) hole, and is positioned opposite the flange (12) and cover (14) from the piston (34) when the cover is positioned over the flange (12). The stud head (42) does not fit through a narrower portion of the anchor plate (18) hole. A resilient member (16) biases the piston (34) away from the cover (14). A selectively activated actuator overcomes the resilient member (16) and forces the stud head (42) away from the flange (12) and the anchor plate (18) moves between (i) a locking position, in which the narrower portion of the hole is aligned with the openings so that the resilient member (16) can bias the stud head (42) against the anchor plate (18), and (ii) an unlocked position, in which the wider portion of the hole is aligned with the openings so that the resilient member (16) can bias the stud head (42) into the enlarged portion of the anchor plate (18) hole.

Title: Low noise encoding and decoding method
Inventor: YU HAOPING
IPC: H04N19/117
Filed: 1997-12-23
Granted: 2011-10-04
Abstract: An adaptive digital image processor (22) precedes an MPEG2 encoder (24). The processor receives a high definition (1920 by 1080 pixels per image) video signal intended for broadcast or storage, and adaptively low-pass filters the signal. The signal is subjected to low-pass two-dimensional filtering (223) to eliminate encoding artifacts and related noise. The video signal is then horizontally down-sampled (226) to create a lower resolution hybrid signal (1280 by 1080 pixels per image). A receiver decodes and decompresses the hybrid signal. The hybrid signal is upsampled to its original resolution using existing hardware and software with a software modification.

IPC: B23K26/04
Filed: 2000-09-07
Granted: 2004-06-01
Abstract: A method and apparatus for real time control of laser beam characteristics in a high power laser-equipped machine tool. A beam path input signal is produced related to changes in the length of the laser beam path as the processing head of the machine tool moves over the workpiece. An integrator produces a signal related to the real time changes in thermal loading of the laser output coupler as the laser beam is applied and as the output power level is adjusted. The beam path and thermal loading signals are used to drive a collimator so as to correct in real time for altered beam characteristics introduced by path length changes and thermal lensing of the output coupler. The result is to maintain control of the beam size at the focus optic. In addition, a further integrator produces a signal related to the real time changes in thermal loading of the focal optic as the laser beam is applied and as the input laser power level is adjusted. This correction signal is applied to the focus optic adjustment mechanism to correct in real time for any shift in the focus optic caused by thermal lensing of that optic.

Abstract: L'invention concerne un système et un procédé permettant de déterminer et d'instituer en temps réel, dans un système de radiocommunication, un saut de fréquence préféré. La vitesse moyenne des stations mobiles à l'intérieur d'une cellule est déterminée ou estimée au moyen de diverses techniques. Si cette vitesse moyenne est inférieure à un seuil prédéterminé, on institue un saut de fréquence cyclique de manière à obtenir une diversité de fréquences plus élevée et par conséquent à lutter contre les amorces d'évanouissement à petite échelle. Si cette vitesse moyenne est supérieure à un seuil prédéterminé, on institue alors une séquence de saut de fréquence aléatoire de manière augmenter le moyennage des interférences et à lutter, par conséquent, contre les interférences inter-canal. On peut également utiliser des retardateurs et l'hystéresis pour améliorer la stabilité et lutter contre les fluctuations à court terme. On répète périodiquement la mesure de la vitesse moyenne et la comparaison de la vitesse moyenne par rapport au seuil.
