Title: Mixed gas refrigeration method
Inventor: DOBAK JOHN D III
IPC: F25B7/00
Filed: 1997-08-06
Abstract: A miniatured mixed gas refrigeration system and method of operation are disclosed, having a coaxial catheter (18) with an inner high pressure supply lumen and an outer low pressure return lumen. An optimum gas mixture is formulated from a group of component fluids, according to calculated thermodynamic properties of a group of candidate fluid mixtures. The gas mixture is pressurized by a compressor (12) to a pressure less than 420 psia, for safety reasons. The distal portion (20) of the outer lumen contains a micro-miniature heat exchanger constructed of laminated plates or sheets. The plates or sheets establish high pressure and low pressure passageways, with high surface area, having a tortuous path for the gas flow to maximize heat exchange. The high pressure outlet of the heat exchanger is connected to a Joule-Thomson expansion element where the high pressure gas is expanded isenthalpically to a lower temperature at least as low as 183K. This low temperature gas cools a heat transfer element mounted in the outer wall of the catheter, to cool an external object. Return gas flows back through the heat exchanger to pre-cool the incoming high pressure gas mixture.

Title: Process for transmitting data in packets on a linearly variable carrier frequency and transmitter and receiver implementing this process
Inventor: HETHUIN SERGE
IPC: H04J13/00
Filed: 1996-10-07
Abstract: The invention concerns the transmission of data packets consisting of a heading followed by a data field. The method consists in transmitting the data of the field by groups of symbols, in generating (5), according to the OFDM  technique, subcarriers modulated by the groups, and producing with the set of modulated subcarriers a frequency modulation (8) of a carrier signal delivered by a linear ramp generator (9). When the signal is received, a mixing (11) with a linear ramp (12) results in obtaining the subcarriers which are separated (13) then demodulated (14) for supplying the data. The invention is useful for transmitting data packets, particularly in wide band networks.

Title: Electrical switchgear with synchronous control system and actuator
Inventor: DUNK MICHAEL PETER
IPC: H01H33/59
Filed: 1999-06-24
Abstract: In a power distribution system, synchronizing switchgear operations with an AC voltage or current waveform can be accomplished more precisely with a closed-loop feedback, microprocessor-based motion control design. By employing a closed-loop feedback, microprocessor-based design, switchgear contact position and velocity can monitored and optimized in real-time during a switching operation, thereby assuring a more accurate switching operation. Moreover, the closed-loop feedback design intrinsically compensates for the affects of such things as ambient temperature, AC waveform fluctuations, and changes in the physical condition of the switchgear. The closed-loop position feedback design is also capable of optimizing various transfer function parameters associated with the closed-loop feedback process, both during and subsequent to a switching operation, to further assure that switching operations are more accurately synchronized with the AC voltage or current waveforms.

Title: An integrated optics chip with reduced thermal errors due to pyroelectric effects
Inventor: ABBINK HENRY C
IPC: G02B6/12
Filed: 1999-07-28
Abstract: An Integrated Optics Chip with improved performance when exposed to changing temperature is disclosed. The optic chip or integrated optic chip or MIOC has a top surface, a +Z face and -Z face. The chip is formed from a crystal having a high electro-optic coefficient such as Lithium Niobate. For the purpose of orienting the components to the optic chip to be described, the +Z crystal axis extends outward from the +Z face, the Z axis being the axis across which a pyroelectric effect is exhibited. The top surface is orthogonal to the Z axis. An input waveguide on the top surface receives an optical signal from an input port, passes the signal via a waveguide network, to an output waveguide coupling the waveguide network to an output port. A portion of the +Z and -Z faces are coated at least partially with a conductive coating. A conductive path couples the +Z and -Z faces to prevent a charge differential from developing between the +Z and -Z faces due to a change in temperature of the optic chip and the pyroelectric effect.
