Abstract: Station de base AMRC améliorée, assurant l'alimentation constante en énergie de chaque branche de récepteur RAKE, ce qui améliore le gain. Entre autres, la station de base comprend un certain nombre de paires d'antennes en diversité. L'énergie de la première antenne de chaque paire est soumise à un retard tandis que celle de la deuxième antenne de chaque paire ne l'est pas. Le retard ajouté est supérieur au temps puce des branches de récepteur RAKE. Les signaux de chaque paire d'antennes sont combinés et convertis sous forme numérique. L'énergie de toutes les antennes est ensuite acheminée aux branches de récepteur RAKE, l'énergie de chaque antenne se trouvant ainsi acheminée à une des branches de récepteur RAKE. L'énergie des branches de récepteur RAKE est ensuite combinée en un unique train de données. Suivant une autre approche, la station de base comprend un certain nombre d'antennes en diversité. L'énergie de chacune des antennes en diversité est soumise à un nombre différent de retards. La différence de retard doit encore être supérieure au temps puce des branches de récepteur RAKE. L'énergie des antennes est combinée, convertie en format numérique et transmise à chacune des branches de récepteur RAKE, l'énergie de chaque antenne se trouvant ainsi acheminée à la branche de récepteur RAKE. L'énergie des branches de récepteur RAKE est ensuite combinée en un unique train de données de sortie.

Title: Intrastromal photorefractive keratectomy
Inventor: BILLE JOSEF F
IPC: A61F9/007
Filed: 1998-08-20
Abstract: A method for performing intrastromal photorefractive keratectomy in the cornea of an eye, using a pulsed, laser beam to photodisrupt a portion of the cornea, includes the initial step of focusing the beam to a focal spot at a selected starting point in the stroma. The starting point is located at a predetermined distance behind the epithelium of the cornea. While focused on the starting point, the laser beam is pulsed to disrupt a volume of the stroma which is approximately equal to the volume of the focal point. Subsequently, the beam is focused in a patterned sequence to focal spots at other discrete points in the stroma. At each point the stroma is photodisrupted. With this progressive pattern of photodisruption, each spot is placed substantially contiguous with adjacent a volume of previously disrupted tissue. The resultant photodisrupted tissue creates a layer which is substantially centro-symmetrical around the optical axis. A plurality of layers can be removed to create a cavity in the stroma. When the cavity collapses, the corneal curvature is changed as desired.

Abstract: This composite consists of an aluminum-alloy matrix containing by volume percent, 0.4 to 8.8 alumina, 1 to 4.4 carbon or graphite and 0.5 to 20 nickel-bearing aluminide. The alumina particles have an average size between 3 and 250 µm and the carbon and graphite particles have an average size between 10 and 250 µm. Thecomposite is cast by stirring alumina and carbon or graphite contained in a molten aluminum or aluminum-base alloy to form a molten mixture. The molten mixture is cast directly from a temperature above the liquidus of the matrix alloy. While solidifying, carbon or graphite particles delay or hinder the settling of alumina to create a more uniform composite structure. The resulting composite structure contains an aluminum-base alloy, alumina, carbon or graphite and nickel-bearing aluminide dispersoids.

IPC: A01N1/02
Filed: 1997-04-10
Abstract: Blood plasma is preserved by drying to an amorphous state, with a glass transition temperature of at least 15 ~C. The glass transition temperature of dried plasma is higher than would be predicted. Consequently, although a carrier material may be mixed with the plasma and included in the dried glassy composition, the weight of plasma solids can exceed the weight of any carrier material. Because admixed carrier can be absent or in low amount, the dried composition can be a unit dose requiring only rehydration prior to transfusion.

The network is capable of two-way communication when requested by the electronic trip unit. Accessory network communication is controlled by a first microprocessor within the electronic trip unit or alternatively by a network interface gateway. The first microprocessor controls voltage based and metering functions while a second microprocessor controls overcurrent and instantaneous protection functions of the trip unit. The second microprocessor also has the capability of communicating with a central control network.
