Abstract: A signal demultiplexer includes serially-connected 2-demultiplexing filter banks, including band-stop filters and down-samplers for culling sampling frequencies of output signals from filters to 1/2. When the 2-demultiplexing filter bank operates on four types of filters, first to fourth filters in an ascending order of frequencies, 2-demultiplexing filter bank is arranged in one of two configurations so that a first filter bank contains at least the first filter or the second filter, or a second filter bank contains at least the third filter or the fourth filter. The filter banks are connected in such a way that signals processed through the first filter are processed by the first 2-demultiplexing filter bank in a next-stage; signals processed through the second filter are processed by the second 2-demultiplexing filter bank in a next-stage.

Abstract: An ejection assembly for ejecting a modem from a wireless communication device is provided. The wireless communication device provides communication capability for a personal data assistant. In one embodiment of the present invention, the ejection assembly includes both an ejector sleeve which holds a variety of modems and a lever arm. The ejector sleeve couples the modem with the wireless communication device to establish connectivity between the wireless communication device and the modem. The ejector sleeve also decouples the modem with the wireless communication device and ejects the modem from the wireless communication device. The modem decouples and ejects from the wireless communication device when a user pushes the ejector sleeve into the wireless communication device, thereby rotating the lever arm. The rotation of the lever arm decouples the modem and ejects the modem from the wireless communication device.

Abstract: In order to manufacture a sandwich panel using the RTM technique, a stack comprising a core (10) with open cells, a film (12) of intumescent material covering each of the faces of the core (10), a dry barrier fabric (14) covering each of the films (12) and an overlay of dry fibers (16) covering each of the barrier fabrics is placed in a mold. During polymerization of the films (12), pressurization of the mold and the presence of the barrier fabrics (14) prevent penetration of the foam into the overlays (16). The resin is then injected into the mold and then polymerized, without danger of penetration into the cells of the core (10).

Abstract: A short distance positioning system for a mobile object with respect to a fixed reference system. The mobile object is equipped with a probe, and at least one resonant circuit enabling reception of a magnetic field. A detection and comparison circuit detects the amplitude of the voltage induced at the terminals of the resonant circuit, thereby deducing the displacement of the probe with respect to the reference system.

Abstract: A process produces a crystal of a material with non-congruent melting using at least one first element and a second element. The process includes (a) placing, in a vertical alignment and maintaining under a controlled atmosphere, a bar of the first element gripped between a lower bar and an upper bar made out of the material, (b) transforming the bar of the first element into a floating zone by heating to a temperature that avoids the evaporation of the first element, the heating being obtained by heating means that provides a temperature gradient in the floating zone so that the lower face of the upper bar appears as a cold face, and (c) contra-rotating the lower and upper bars around the alignment axis and moving the whole bar assembly upwards in relation to the heating means in order to obtain the crystal on the cold face by growth in solution.
