Title: Drillpipe structures to accommodate downhole testing
Inventor: JOHN HENDRIK
IPC: E21B47/01
Filed: 1999-05-13
Granted: 2005-10-25
Abstract: A drill collar structure to facilitate measurement-while-drilling (MWD) techniques while at the same time having sufficient rigidity to facilitate the drilling operation is disclosed. In some embodiments, a metal structure involving openings such as slots, preferably oriented longitudinally along its axis, but also in other configurations, are disclosed to allow sufficient strength while at the same time allowing exit and entrance of electromagnetic energy.  A composite structure is also disclosed which, for given layers, has adjacent fibers such as glass and carbon, so that when the layers are overlapped, glass areas overlap glass areas throughout the radial thickness of the composite tube to create "windows" for the entrance and exit of electromagnetic energy. In yet other embodiments, the drill collar can be made of a metallic frame structure with a multiplicity of openings which are filled with a composite material. The metallic frame structure provides structural rigidity while the openings, filled with composite material which are attached to the metal structure, form a fluid-tight cohesive structure sufficient to withstand the rigors of drilling, while at the same time allow the measurements of the formation to be taken through the windows or by making use of sensors embedded in the windows. In another alternative composite structure, carbon fibers can be used if they are electrically insulated in the areas where electromagnetic energy is to enter and exit the structure. Another composite alternative is to alternate carbon and glass fibers in particular sequences or to use insulated carbon fibers to facilitate the operation of instruments which can be mounted in the structure whose operation could be negatively affected by conductivity in the wall in an azimuthal direction.

Abstract: Produit (44) de papier soie doux comportant des dépôts en surface d'une composition d'additif située dans des zones d'apport primaires (46) et supplémentaires (48) dotées de quantités d'ajouts différentes. La quantité d'ajout supplémentaire est supérieure à 0 et inférieure à la quantité d'ajout primaire. Par exemple, la quantité d'ajout supplémentaire peut être située entre environ 0,5 et environ 80 % de la quantité d'ajout primaire. Dans des modes de réalisation spécifiques, les zones d'apport primaires (46) couvrent entre environ 30 à environ 90 % du papier soie et les zones d'apport supplémentaires (48) couvrent entre environ 10 à environ 70 % du papier soie. Les différentes quantités d'ajout augmentent au maximum et de manière efficace le bien-être des consommateurs tout en réduisant au minimum la quantité totale d'additif sur le papier soie. Un procédé particulièrement rentable consiste en l'application uniforme de la composition sur la surface du voile du papier soie à l'intérieur de chacune des zones, au moyen d'une impression par rotogravure, directe ou indirecte (offset), parce qu'il s'agit d'un processus d'impression très précis qui offre une régulation maximale de la répartition de la composition et de son taux de transfert. Cependant, on peut également utiliser d'autres procédés d'applications, tels que l'impression flexographique, la pulvérisation, l'extrusion et d'autres procédés du même genre. Un rouleau gravé (23A, 23B) approprié à l'utilisation dans l'application des additifs au papier soie (44) est gravé avec deux zones différentes (40, 42, 50, 52) de dessins de cellules.

Abstract: Resolution of contention over resources -in an automatic call distribution (ACD) system is effected as follows. Call attributes are defined for arriving calls, and resource attributes are defined for available resources. Rules are defined that match calls having particular call attributes with resources that have corresponding resource attributes.      Priorities are assigned to rules, comprising an initial value and a time function that defines how the value changes over time. Each rule preferably defines a coverage path for calls, comprising one or more resource attributes required of resources that can handle the call if the primary resources identified by the rule cannot handle the call in a timely manner. Each resource has an associated call queue. When a call arrives, rules are matched to the call's attributes, and the matching rules determine the resources that are able to handle the call. A token for every matching rule for the call is placed in the queues of all of the resources that are able to handle the call. The position of the call's token in a queue is determined by the priority of the rule. The priority, and hence the call's position in the queue, changes over time according to the rule's time function. When one of the resources removes the call's token from its queue to process the call, all tokens for the call are removed from all queues. When a token with a priority higher by a threshold amount than the priority of the call being processed by the resource appears in the resource's queue, processing of the call is preempted by the token's call

Title: Supporting concentrator in multiple paging channel environment
Inventor: PITTAMPALLI ESHWAR
IPC: H04W68/00
Filed: 2000-03-15
Granted: 2005-05-10
Abstract: A paging signal is detected where the paging signal is intended for a mobile- telephone having a paging channel frequency that is different than a paging channel frequency associated with a concentrator. A base station transmits a base station-to-mobile (BS-MT) paging message by including such BS-MT paging message in a base station-to-concentrator (BS- C) paging message. The BS-MT paging message includes a message portion and a mobile- telephone identifier portion, wherein the mobile-telephone identifier portion indicates the mobile-telephone to which the BS-MT paging message is for indicating the concentrator to which the BS-C is intended. The BS-C paging message is transmitted over a paging channel on a frequency f1 associated with the intended concentrator (i.e., concentrator through which the mobile-telephone is linked to the base station). The intended concentrator detects the BS-C paging message by monitoring its associated paging channel on frequency f1 for a BS-C paging message with a concentrator identifier portion indicating the concentrator. Upon detecting its BS-C paging message, the concentrator parses the BS-MT paging message from the BS-C message and transmits the BS-MT paging message to the intended mobile-telephone using a paging channel on frequency f2 being monitored by the mobile-telephone.

Title: Forwarding variable-length packets in a multiport switch
Inventor: AYBAY GUNES
IPC: H04L12/56
Filed: 1999-05-13
Granted: 2003-09-23
Abstract: A method and apparatus for forwarding variable-length packets between channel-specific packet processor (82, 84, 86 and 88) and a crossbar (60) of a multiport switch involve segmenting variable-length packets (150) into fixed-length payload segments and multiplexing the payload segments with response or request data to form fixed-length switching blocks (160). The fixed-length switching blocks are transferred to and from the crossbar over respective input and output connections in order to minimize the number of connections between the packet processors and the crossbar. The input and output connections enable the transfer of a current packet through the crossbar while supplying the crossbar with request information necessary to schedule subsequent packets through the crossbar. In a preferred embodiment of the invention, packets are timed to pass through the crossbar one after another in order to utilize the maximum bandwidth of the crossbar.
