Title: Time division multiplex switching system for interconnecting telephone circuits which operate in accordance with different signalling systems and call formats
Inventor: BREIDENSTEIN CHARLES J
IPC: H04Q11/04
Filed: 1992-07-23
Granted: 1999-01-19
Abstract: A time division multiplex switching system converts call formats and signalling protocols so that calls can be interchanged between circuits originating in different networks thereby providing a gateway for telephone transmissions originating from sources (e.g., foreign countries) having differences in transmission (signal attenuation characteristics and companding laws) and signalling and numbering plans or protocols.  This switching system is characterized by a processor which is programmed to identify the circuits requiring interconnection and to process signalling messages in accordance with the signalling systems and formats used in the circuits, while translating the signalling messages into common, protocol independent signaling messages which are used for establishing time division multiplex connections in a time slot interchange which is connected to the circuits via PCM highways and for exchanging signalling information (e.g., as to seizure, detection and release) between the circuits; the signalling messages also containing information for conversion of PCM data messages which are switched in the time slot interchange thereby reconciling differences in transmission, such as the companding law used for PCM encoding and decoding and the attenuation (pad value) of the call data in the circuits.  The circuits may, for example, be incoming and outgoing trunks.

Filed: 1992-07-30
Granted: 1996-11-12
Abstract: An mxn (m > n) output Packet Switch Unit is implemented by using an nxn Packet Switch Module and an m:n Concentrator. The arriving packet cells are supplied from the m Concentrator inputs to the n Concentrator outputs in a "first-in first-out" (FIFO) sequence. The Concentrator provides for buffering of arriving packet cells on the m Concentrator inputs in excess of available packet cell positions in the n Concentrator outputs until they can be supplied to a Concentrator output in the FIFO sequence. In turn, packet cells from the n Concentrator outputs are supplied to n inputs of the Packet Switch Module which supplies them to appropriate output destinations associated with the n outputs of the Packet Switch Module. A plurality of the Concentrator-Based output Packet Switch Units is readily employed to implement any "larger" Packet Switch architecture.

Title: Non-invasive blood glucose measurement system
Inventor: TARR RANDALL V
IPC: G01N21/65
Filed: 1991-11-12
Granted: 1998-08-11
Abstract: Stimulated Raman spectroscopy is used to non-invasively measure the concentration of a Raman active molecule, preferably D-glucose in the ocular aqueous humor of living being. The apparatus and method make use of two monochomatic laser beams, a pump laser beam and a probe laser beam. The output power of the pump laser beam is amplitude modulated, combined with the probe laser beam and directed into the ocular aqueous humor. The introduction of the laser beams into the ocular aqueous humor induces scattered Raman radiation, which causes a portion of the energy at the pump frequency to shift over to the probe frequency. The pump and probe laser beams are then detected as they exit the ocular aqueous humor. The probe laser beam is filtered, converted into an electrical signal and amplified. It is then compared to the modulation signal to generate an electrical signal representative of the concentration of D-glucose in the ocular aqueous humor.

Title: High pressure atomization systems for high viscosity products
Inventor: BUISSON GERARD LAURENT
IPC: B05B11/00
Filed: 1994-09-20
Granted: 1999-05-04
Abstract: The present invention pertains to improved manually operated atom-ization systems which combine atomizing nozzles with high pressure, pre-compression type pump mechanisms in order to provide a consistent, high quality, finely-atomized spray of a comparatively higher viscosity fluid. The pre-compression pump mechanism ensures that the product will only be de-livered when sufficient pressure is available for atomization regardless of the speed or authority with which the pump mechanism is actuated. When the fluid is discharged from the nozzle in a swirling, conical film, the fluid is broken up into a finely-dispersed mist which may then be directed toward the surface to be coated. Pump mechanisms for use with the present invention incorporate specific design features which facilitate the flow of comparatively viscous fluids with reduced flow resistance and hence reduced pressure losses, as well as providing enhanced structural integrity to better withstand such op-erating pressures and forces while providing improved reliability. The com-bination of pre-compression and comparatively higher operating pressures ensures that the comparatively higher viscosity fluid will be delivered to the nozzle with a pressure (and hence a velocity) that is comparatively high and within a comparatively narrow range. This in turn ensures a finely-dispersed product spray with a comparatively narrow range of particle sizes, under a wide range of actuation circumstances.
