Abstract: L'invention concerne une technique de gestion de trafic dans des systèmes de télécommunications sans fil à spectre étalé au moyen de couches de fréquences différentes de niveaux de commande d'admission. Dans un mode de réalisation, la capacité d'une première fréquence possédant un niveau de commande d'admission spécifique, augmente jusqu'au point de développement de trous de couverture sous l'effet de la respiration des cellules. On corrige ce phénomène par maintien d'une fréquence déterminée exempte de problèmes de couverture au moyen de l'application d'une commande d'admission plus stricte par rapport à la première fréquence. Par conséquent, les appels ou de nouvelles tentatives de communication subissant des problèmes de couverture à la première fréquence sont déviés vers la fréquence déterminée. Ce procédé permet d'améliorer la capacité générale du réseau et la qualité des appels sur ce réseau au moyen d'une utilisation plus efficace des ressources spectrales.

Abstract: A taxi has four radially extending arrays of LEDs (38A to 38D) mounted one o n each hub cap. A local receiver (32A to 32D) in each hub cap receives data representing a desired image from a local transmitter (24) and stores it in a local memory (34A to 34D). A local control unit (36A to 36D) in each hub cap selectively energises the LEDs in the associated array (38A to 38D) in the required sequence (as the hub cap rotates) to produce an apparent image corresponding to the desired image. A central control station (2) supplies data representing the desired image to a receiver (14) in the taxi. This dat a is only stored in an associated store (20) when a gate (18) responds to a co de in the transmitted data corresponding to that particular taxi. The stored da ta is then downloaded from the memory by the local transmitter (24).

Title: Submersible motor with shaft seals
Inventor: ANDREWS DALE
IPC: F04D29/10
Filed: 2000-09-29
Granted: 2010-04-06
Abstract: A submersible electric motor driven pump has a motor chamber and a pump chamber separated by a seal chamber. Inboard and outboard shaft seals(MS1,MS2) immersed in an oil buffer fluid within the seal chamber restricts the flow of liquid from the seal chamber into the pump and motor chambers. An integral or externally mounted pre-pressurized buffer fluid reservoir (PA) maintains a positive fluid pressure in the seal chamber relative to the external pressure at working depth, and maintains a suitable buffer fluid level within the seal chamber, in order to prevent the ingress of the pumped media through the outboard seal(MS2). A unique impeller design (631) circulates fluid within the seal chamber in the region of the outboard shaft seal (MS2), allowing continuous dry run operation when used in conjunction with an integrally cooled motor design. A cartridge shaft sleeve subassembly, having a bearing (3) configured between the inboard and outboard seals (MS1,MS2), facilitates maintenance.

Abstract: This invention describes new LED structures that provide increased light extraction efficiency. The new LED structures include arrays of electrically interconnected micro-LEDs (12) that have an active layer (14) sandwiched between two oppositely doped layers (16, 18). The micro-LEDs are formed on a first spreader layer (18) with the bottom layer (16) of the micro-LEDs in contact with the first spreader (18). A second spreader layer (24) is formed over the micro-LEDs (12) and in contact with their top layer (16). The first spreader layer (18) is electrically isolated from the second spreader layer (24). Each of the spreader layers (20, 24) has a contact (22, 26) and when a bias is applied across the contacts (22, 26), currents spreads to the micro-LEDs (12) and they emit light. The efficiency of the new LED is increased by the increased emission surface of the micro-LEDs (12). Light from each of the micro-LEDs active layer (14) will reach a surface after travelling only a short distance, reducing total internal reflection of the light. Light extraction elements (LEEs) (82, 84, 86, 88, 90, 92, 94) between the micro-LEDs (12) can be included to further enhance light extraction. The new LEDs are fabricated with standard processing techniques making them highly manufacturable at costs similar to standard LEDs.

Abstract: A system for forming and packaging loose particulate material utilizing a compression tower (100) for initial deposit of the loose material therein with the bottom floor of said tower being presented by a belt (310) of a conveyor system (300). A ram within the tower compresses the loose material into a bulk form (1000) atop the conveyor belt (310). Subsequent to compression, the conveyor system (300) is vertically displaced so that the formed material bulk can be conveyed to a horizontally adjacent conveyor (550) for downstream conveyance to a packaging station (550) having upper (700) and lower (600) conveyor assemblies. The material bulk (1000) is then recompressed and conveyed to a space formed between the upper and lower assemblies. Sheets of packaging material (800a, 802a) spans portions of upper and lower conveyor assemblies such that the material bulk is directed through the sheet and enveloped thereby. Packaging material which envelopes the bulk material is cut and thermally sealed leaving the packaging sheets spanning the conveyor assemblies.
