Granted: 2001-04-03
Abstract: An EAS system in which a transmitter alternately drives first and second antennas with the same coded message signal in its entirety.  The antennas, in turn, transmit first and second signals each containing the coded message signal into respective first and second partially overlapping parts of an interrogation zone.  Also disclosed is an antenna structure comprised of a plurality of loops extending one after the other and successive ones of which are of opposite phase. One of the loops circumscribes an area which is smaller than each of the other loops to realize reduced coupling to adjacent structures.

Abstract: L'invention se rapporte à un système de commande (10) et un procédé de fonctionnement d'électrodes bipolaires de neurochirurgie (11). Une source d'énergie haute fréquence (13') est reliée aux électrodes bipolaires (11), dont les surfaces de contact sont en matériau hautement électro-conducteur. Un transducteur d'intensité fixé à la source d'énergie haute fréquence (13') mesure (20) l'intensité efficace appliquée entre les surfaces de contact (25). Un transducteur d'intensité fixé à la source d'énergie haute fréquence (13') fournit un signal (26) corrélé aux valeurs instantanées de l'intensité entre les surfaces de contact. Un dispositif de commande relié à la source d'énergie haute fréquence (13') permet de réguler initialement l'intensité efficace appliquée par les surfaces de contact, en réponse à l'impédance, jusqu'à ce que le signal (19) divisé par la mesure (20) représentative de l'impédance instantanée de la charge atteigne une valeur prédéterminée. Le système de commande permet de réguler l'intensité efficace appliquée par les surfaces de contact, en fonction de l'impédance, jusqu'à ce que le signal (19) divisé par la mesure (20) atteigne une valeur prédéfinie. Le système de commande réagit à la mesure (20) et au signal (19) de sorte que la tension efficace appliquée à la charge traitée entre les surfaces de contact soit régulée, l'impédance étant contrôlée jusqu'à ce que sa valeur atteigne un seuil prédéterminé. Le système de commande régule la tension efficace appliquée en fonction de l'impédance en modifiant la valeur de cette tension selon un pourcentage donné, jusqu'à ce que la valeur préétablie soit obtenue, de sorte que les tissus restent humides et soient coagulés sans séchage et carbonisation ou transformation en escarres.

Abstract: Apparatus (300) is disclosed for locking a key (322) in a keyway (302) of a shaft (10) and of a hub slideably receiving the shaft (10). The key (322) is  tapered and includes a top extending at an acute angle to the bottom, with t he keyway (302) of the shaft (10) having a bottom wall (306) at the acute angle  to the axis of the shaft (10). A push rod (312) is rotatable in an axial bor e (308) in the shaft (10) and includes a threaded portion (318) threaded into a threaded counterbore (310) of the axial bore (308). The forward end of the push rod (312) is interconnected to the key (322) by a lip (336) formed in t he key (322) extending into a notch (316) formed in the push rod (312).

Abstract: During the registration process by which a connection is set up between a mobile telephone and a base station of a mobile telephone network the telephone acquires program data from the network for controlling its operation. This allows upgrades of the system to be provided automatically t o the mobile telephone. The mobile telephone (1) and base station (10) each ha ve a memory (7, 19) for storing program data relating to one or more modes of operation. During the registration process the base station (10) transmits a  signal indicative of a preferred mode of operation. The mobile telephone (1)  responds with a signal indicative of whether its memory (7) already contains  program data for this mode of operation. If the signal indicates that the memory (7) does not have this program data, the base station (10) transmits the required program data to the mobile telephone (1). The base station (10)  and mobile telephone (1) can then operate in this mode. A check is made to establish if the mobile telephone (1) is able to accept the data. If it is n ot so capable (for example because it has insufficient memory), the process is repeated with different programs until a program is identified for which the re is sufficient capacity in the memory (7). If a call attempt is initiated before this process is complete, the process is curtailed, such that the bas e station (10) and mobile telephone (1) identify programs already stored in th e memory (7), but make no attempt to load a new program, as this could delay call set-up. If the base station (10) receives no response to its initial indication of a preferred program, as would occur if it establishes contact with a conventional (non-programmable) mobile telephone, the base station (1 0) operates in a default mode.

Abstract: A method of regulating drilling conditions applied to a given well bit comprises assaying the compressive strength of the formation in an interval to be drilled by said bit. Wear of critical bit structure of the same size and design as in said given bit and which structure has drilled material of approximately the same compressive strength as that so assayed, is analyzed along with respective drilling data for the worn structure. From said analysis, a power limit for the respective compressive strength, above which power limit excessive wear is likely to occur is determined. Drilling conditions, such as rotary speed and weight-on-bit, at which the given bit is operated are regulated to maintain a desired operating power less than or equal to the power limit. Where several feasible rotary speed/weight-on-bit combinations may result in the desired operating power, these conditions are optimized.</ SDOAB>
