IPC: F04B39/00
Filed: 2000-10-05
Abstract: - A compressor assembly including a housing, a motor and a compression mechanism disposed within the housing, the compression mechanism driven by the motor. A pulsating discharge fluid flow emanates from the compression mechanism through a first conduit; the first conduit having an outlet which is open to a discharge muffler chamber. A standing pressure waveform is established by the first pulsating discharge fluid flow within the discharge muffler chamber. A second conduit is provided which has an inlet which is open to the discharge muffler chamber and disposed outside the standing pressure waveform therein, and an outlet through which discharge fluid exits, whereby the magnitude of the discharge pulse transmitted by the discharge fluid is attenuated. The present invention also provides a compressor assembly including a compression mechanism and a discharge muffler chamber having a substantially hemispherical inner surface and a central axis. First and second conduits are in fluid communication through the discharge muffler chamber, the openings of the first and second conduits within said discharge muffler chamber are directed substantially towards the central axis and oriented at approximately a right angle relative to each other therealong. A discharge fluid flow is received in the discharge muffler chamber from the compression mechanism via the first conduit. The discharge fluid flow contains pressure pulses of a fast magnitude. The discharge fluid flow is exhausted from the discharge muffler chamber via the second conduit, the discharge fluid flow exhausted from the discharge muffler containing pressure pulses of a second magnitude less than the first magnitude.

Title: Commande de modulateurs photoelastiques resonnants
Inventor: BUICAN TUDOR N
IPC: G02F1/11
Filed: 1999-03-16
Abstract: La présente invention concerne un système et un procédé permettant de tirer profit du fait que la fréquence de résonance d'un modulateur photoélastique (PEM) dépende de la température (due à l'amplitude d'excitation et à la température ambiante), afin d'améliorer de manière générale les performances des PEM. Dans un des modes de réalisation, un procédé et un système permettent de piloter efficacement une série de PEM multiples. Pour ce faire, chacun des PEM dans un empilement est syntonisé séparément, par exemple, en commandant l'énergie qui se dissipe dans chaque empilement, de sorte que les fréquences de résonance de tous les PEM convergent vers une fréquence commune. Ainsi, tous les PEM se trouvent simultanément à une résonance propre pour assurer une efficacité maximum et conserver une amplitude de ralentissement totale choisie. Dans un autre mode de réalisation, un PEM à composant unique est commandé de façon à prendre en considération les légères variations de la fréquence de résonance du PEM. A cet effet, un procédé et un système permettant de maintenir constantes à la fois l'amplitude de ralentissement du PEM et sa fréquence de fonctionnement réelle, laquelle fréquence n'est pas nécessairement une fréquence de résonance.

IPC: G02B30/60
Filed: 1999-03-19
Abstract: Apparatus for displaying an image suspended in space comprises an object (1) for display, a retroreflector (2) receiving light from the object, a beamsplitter (3) in a path for light from the object to the retroreflector, and a concave mirror (4) between the beamsplitter and the retroreflector. The beamsplitter makes an oblique angle to the direction (6) of propagation of the light such that it transmits some light. Light from the beamsplitter is reflected by the mirror to the retroreflector which reflects it back via the mirror to the beamsplitter. This retroreflected light is reflected by the beamsplitter to form a real image (5) suspended in space. The use of a concave mirror improves viewability over apparatus including a converging lens because unwanted reflections from the surfaces of the lens are eliminated.

Abstract: A patch antenna is described with enhanced beamwidth characteristics. In a first embodiment, the antenna comprises a patch element and a ground plane separated from the patch element by a first dielectric layer. The antenna further includes a signal feed line separated from the ground plane by a second dielectric layer, the signal feed line being shielded from the patch element by the ground plane. The signal feed line is electromagnetically coupled to the patch element through an aperture in the ground plane lying across the signal feed line, the ground plane functioning as a finite surface relative to the aperture. According to a further aspect of the invention, the beamwidth of the antenna is adjusted by adjusting the position of a reflector behind the signal feed line. Thus, the present invention provides an efficient way to achieve adjustable wide-beamwidth for various wireless systems in a three-sector configuration.

Abstract: A buffer management scheme for a shared memory in an ATM switch sets differe nt dynamic thresholds (18) for different Vcs (10) according to the formula: Tsu b i (U) = Tsub Fsub i + gama sub i . (B - U) where B is the total size of the shared buffer and U is the size of the used portion of the buffer. According  to the invention, Tsub i (U) is the threshold (in number of cells) for the i th connection when the used portion of the buffer is U, Tsub Fsub i is the required buffer allocation (in number of cells) for the ith connection buffe r when the buffer is full and gama sub i is a power of two chosen for the ith connection at the time the connection is set-up. Both Tsub Fsub i and gama s ub i are chosen based on the service category of the connection (12). In addition, the buffer management scheme sets minimum and maximum buffer sizes  based on the service category of the connection. Preferably, a minimum buffe r is guaranteed for service categories above UBR (unspecified bit rate). For U BR traffic, the minimum buffer available is determined by the number of backlogged connections. The maximum buffer size for each connection is a function of the total buffer size B, Tsub Fsub i and gama sub i.

Abstract: The present invention provides novel "patch in a bottle" technology in which  a fluid composition, e.g., an aerosol spray, is applied onto a surface as a fluid, but then dries to form a covering element, such as a patch, having a tack free outer surface covering an underlying adhesive that helps adhere th e patch to the substrate. The fluid compositions have a unique chemical formulation that allows such composite patches to form in situ. Specifically , the fluid compositions include a tacky component, such as an adhesive, and a  film-forming, non-tacky component. The non-tacky and tacky components are selected to be immiscible with each other so that the components undergo pha se separation as the fluid compostion dries.
