Title: Method and device for accessing a communication medium shared between users transmitting with different priority levels in a circuit or packet mode
Inventor: LE COMTE MICHEL
IPC: H04L12/413
Filed: 1990-04-03
Abstract: A requesting user transmits, on a contention bus (BC) common to the users, a priority datum comprising his priority level and his address, and each user stores (in RI0 and REI1) the priority data arriving via the contention bus in order to determine, through comparison between the priority data of the requesting users, which one is authorised to transmit in each of the elementary time channels forming the time frame. A user having begun to transmit in one or more time channels may be interrupted before the end of his transmission by another requesting user effecting an override by virtue of a higher priority datum, the successive interruptions possibly being concatenated. The contexts of the interrupted communications are saved (in MC, MT) in the order of the successive interruptions, and exit in the reverse order when the communication medium becomes available again, the contexts of the most recently interrupted communications exiting first. <IMAGE>

Abstract: The device comprises a baseplate (10) intended to be fixed onto one wall of the reservoir, a support (30) articulated around a horizontal axis (34) on the part of the baseplate (10) which is internal to the reservoir, a slider (40) carried at the lower extremity of the support (30) in such a way that the slider (40) rests against the bottom of the reservoir, a resistive element (20) carried by the support (30), a float (50) carried by an arm (60) which is articulated around a non-verticle axis (62) on the support in order to follow the fuel level, and a cursor carried by the arm (60) and resting on the resistive element in order to define a resistance which is variable as a function of the level of liquid contained in the reservoir, characterised by the fact that the geometry of the slider is such that whatever the position of the bottom of the reservoir, by reason of possible deformation of the reservoir, when the fuel level corresponds to the same minimum measurable height, the arm (60) of the float always occupies the same relative position with respect to the support (30).

Abstract: Le système radio selon l'invention comprend une station centrale (1) et une station terminale passive (2). Des premier et second signaux de données (D12, D21) sont transmis entre des unités de traitement de données (U1, U2) respectivement connectées aux stations centrale et terminale. Le système radio est essentiellement caractérisé en ce que la station terminale comprend un même circuit (22) de faible coût associé à une antenne plane carrée (20) pour détecter l'amplitude d'une première micro-onde incidente (PA) émise par la station centrale afin de récupérer le premier signal de données pour produire en retour une micro-onde modulée en phase (PP) par le second signal de données par rétroréflexion d'une seconde micro-onde incidente (P). Cette seconde micro-onde incidente (P) est émise par la station centrale vers l'antenne plane carrée de la station terminale. La station terminale est de conception très simple et peu encombrante et peut être incluse ainsi que l'unité de traitement de données correspondante dans une carte à puce sans contact.

Abstract: Electronic detector-array synthesis techniques provide fast, precise and accurate digital control of electronic zoom for electro-optical scanning systems. 
     The output signals (34) of exponentially-spaced detectors (52-67) are first added to synthesize (38) several binary-sized groups (1x-n, 2x-n, 4x-n, 1/2x-n, 1/4x-n) of n equivalent detectors (for n recording channels). These groups (40̸) are sequentially selected (42) by multiplexers (10̸6) controlled by the most-significant bits (m.) of the size-control word (m.c). The selected group (44) of signals are interpolated (46) by a voltage-divider network (or by time-division multiplexer network) over a size variation of a factor of two, controlled by the least-significant bits (.c) of the size-control word (fig 13). 
     Scaling is provided by sampling (136), digital conversion (140̸) and temporary storage (144) of the n signals (48) at a rate directly proportional to instantenous range R (H/COS(A)). The n synthetized detector signals (142) are stored and converted back to analog signals at a constant rate for display or recording.

Abstract: This invention relates to a method and apparatus for transmitting constant and variable bit rate traffic in a broadband ISDN switch. Data from constant bit rate sources such as television cameras is entered into a group of queues (134,136,138,139). Each member of the group for queuing data of a different band of bit rates. Data is transmitted from these queues with highest priority from the queue storing data of the highest band of bit rates. If the longest enqueued entity of data in one of the other queues has been enqueued for more than a prespecified period, its priority is increased. Analytic studies have shown that use of three queues for constant bit rate traffic and a fourth queue for variable bit rate traffic allows a high occupancy in the output channels to be maintained with a negligible number of data entities excessively delayed.

Abstract: The invention provides a magnesium manganese alloy suitable for use in the production of a pellet 10 for administration to a ruminant by dposition in its rumeno-reticular sac. A typical pellet 10 comprises a magnesium alloy tube 12 enclosing a degradable core formed of plurality of tablets 14, 16. The magnesium alloy used in the construction comprises at least 90% by weight of magnesium, uyp to 1% zinc and up to 2% of manganese. Preferably the alloy may further include aluminium, silicon or zirconium along with iron and beryllium. When deposited in an animal's rumen the alloy reacts with the rumen juices to form an anodic film over the exposed surface of the tube 12. This prevents corrosion or dissolution of the tube 12 except at its exposed ends where galvanic corrosion by coupling with the electrically conductive core 14, 16 is provided. The normal requirement of a non-degradable exterior coating e.g. resin for the tube exterior is obviated.
