Title: Amorphous compounds for wideband optical amplifiers
Inventor: FEJER MARTIN M
IPC: H01S3/06
Filed: 2000-07-28
Abstract: In a method of amplifying optical input signals over a wide bandwidth, the optical input signals are applied to an optical waveguide (810) made from a rare-earth-doped amorphous material (e.g., erbium-doped yttrium aluminum oxi de material). The optical input signals include optical signals having wavelengths over a range of at least 80 nanometers, and, preferably, over a range of at least 160 nanometers. Pump light (830) is applied to the optical  waveguide (810) to cause the waveguide (810) to provide optical gain to the optical input signals. The optical gain causes the optical signals to be amplified within the waveguide (810) to provide amplified optical signals ov er the extended 80-160-nanometer range, including, in particular, optical signa ls having wavelengths at one end of the range and optical signals having wavelengths at a second end of the range.

Title: Two-way trap
Inventor: ANGUERA FONT JUAN
IPC: E03C1/284
Filed: 2002-01-08
Abstract: The purpose of the invention is to prevent the blockages that occur in the general drainage traps of buildings. The invention consists in connecting a conduit by positioning it in the inlet part above the trap water float level (M) and in the outlet part below a line (N), thereby forming a new auxiliary trap. The invention is suitable for use in traps in buildings which are connected to the common sewerage system. Said invention provides a technical solution that prevents the obstruction of the trap by means of an alarm which is installed in the conduit wherein the water is diverted due to gravity when the conduit is obstructed. Said alarm signals any obstruction in the conduit so that it can be cleared without waiting for the consequences of such a situation to occur. Other versions of the invention consist in installing said conduit in the upper or lateral part of the trap, on the connection points indicated.

Title: Disruption of plant material to readily hydrolyzable cellulosic particles
Inventor: HATA SEIJI
IPC: C08H8/00
Filed: 2001-01-16
Abstract: A process for disrupting cellulosic biomass into a readily hydrolyzable cellulose powder consisting of gradually hydrating the paracrystalline cellulose while applying mechanical forces to strip away cellulose polymer chains as soon as the hydration negates the hydrogen bonds between adjacent polymer chains. A preferred way of attaining disruption is to rapidly agitate particles of cellulosic biomass in a container to form a gaseous suspension of the particles. The temperature of the suspended particles is raised and water is gradually introduced as a fine spray or as a vapor. The cellulosis particles become increasingly hydrated without the obvious presence of liquid water. The particles can be periodically dehydrated by increasing the rate of mixing while stopping the addition of water while venting water vapor to the atmosphere. The ultimate product is an extremely fine cellulosic power that is extremely susceptible to either chemical hydrolysis or enzymatic digestion to yield simple sugars.

Title: Patient condition display
Inventor: TARASSENKO LIONEL
IPC: G16H30/40
Filed: 2002-05-29
Abstract: Data from a plurality of sensors representing a patient's condition, includi ng the measurement signals and also secondary parameters derived from the measurement signals, are displayed in a simple way by mapping them from the multi-dimensional measurement space to a two-dimensional visualisation space . This can be achieved using a mapping which preserves the topography of the data points, for instance by ensuring that the inter-point distances in the visualisation space match as closely as possible the corresponding inter-poi nt distances in the measurement space. Such a mapping, for instance Sammon's mapping is achieved by a suitably trained artificial neural network. The parameters are normalised before the mapping process and the normalisation a nd mapping are such that mapped points from a patient whose condition is normal appear in the centre of the visualisation space, whereas points from a patie nt whose condition is abnormal appear at the edge of the visualisation space. T he artificial neural network may be trained using data points from a single patient or from a group of patients, and data may be thinned out using a pre - clustering algorithm.
