Title: Method for the management of radio resources during the transmission of packets
Inventor: RAMEL LOUIS
IPC: H04J13/00
Filed: 1996-05-22
Abstract: The disclosure relates to the transmission of data by packets, in a network, with a search for an optimum use of the allocated band of frequencies.  The packets are all formed by a header followed by an information field.  The headers are all sent out on the same carrier frequency and the radio resources allocated to an information field are limited to a parallelogram demarcated by two first parallels corresponding to two fixed frequencies external to the frequencies allocated to headers and by two second parallels that have the same frequency/time slope for all the packets and whose position in time is deduced from the observation of the header.  Thus, with knowledge of the resources used by the packets that are being transmitted, a terminal may send out a new packet as closely as possible to the packets that are being transmitted, but without any risk of interference with these packets.  Application to transmission by packets.

Inventor: MARX GERARD
IPC: A61P17/02
Filed: 1995-02-08
Abstract: The present invention describes a biologically compatible bioadhesive composition fibrin glue and liposomes for use in mammals, including humans. Fibrin glue of the invention comprises fibrinogen and thrombin which are mixed together in various modes with liposomes and applied to a site of injury, to a wound, or to a surgical or nonsurgical incision or opening. In accordance with the invention, the liposomes are embedded within the fibrin glue after coagulation has occured, and may release bioactive substances contained within their acqueous interiors to promote healing and protection during the recovery process. The bioadhesive composition of the invention promises to maintain hemostasis after surgeries and improves upon existing glues or gel formulations due to its complete biological compatibility, its formation in situ, and its provision of bioactive therapeutics via entrapped liposomes directly to the site. Long-lasting biophysical and biomechanical properties as well as therapeutic value are imparted to the fibrin glue components by the liposome component of the composition.  The bicompatible fibrin glue and liposome composition is also amenable for fabrication into films, coatings, or membranes for in vitro and in vivo uses.

Title: Absorbent gelling material comprising a dry mixture of at least two types of hyrogel-forming particles and method for making the same
Inventor: SCHMIDT MATTIAS
IPC: A61F13/49
Filed: 1995-07-03
Abstract: By mixing two types of hydrogel-forming particles having different Absorption Against Pressure values, a synergistic effect can be obtained wherein the AAP-value of the mixture is higher than would be expected on the basis of the weight fractions of the components of the mixture. By mixing two types of hydrogel-forming particles having different Teabag Centrifuge Capacity values and equal AAP values, an unexpected increase in the AAP value of the mixture is observed. A method of manufacturing the absorbing gelling material according to the invention comprises the steps of: providing a first type of hydrogel-forming material and a second type of hydrogel-forming material;  introducing both types of hydrogel-forming material in a mixing means; and mixing both types of hydrogel-forming particles to form the mixture. Both types of hydrogel-forming material may be formed by a separate polymerisation process in separate batches, followed by mixing the two types of hydrogel-forming particles. Alternatively, a weight fraction of a single type of hydrogel-forming material may be separated from the bulk of the material, may subsequently be treated to increase the AAP value thereof, and may be mixed back into the bulk material.
