Title: Communication through a channel having a variable propagation delay
Inventor: CUTLER VICTOR H JR
IPC: H04J3/06
Filed: 1994-11-15
Abstract: A communication system (10) communicates real time data through a channel (26) that imposes delays of variable duration on signals propagating therethrough. The channel (26) may be established between a fast-moving satellite (14) in an orbit (28) around the earth and a subscriber unit (24) located proximate the earth' surface.  The real time data are generated synchronously (124) at the subscriber unit (24) with a TDM frame (40) established by the satellite (14).  The data are delayed in a variable delay circuit (68) before transmission through the channel (26).  The duration of the delay imposed by the delay circuit (68) varies in response to timing data received from the satellite (14).  The timing data describe a changing propagation delay for the channel (26) and changing definitions for TDM time slots (42', 44').  Data received at the subscriber unit (24) are delayed in another variable delay circuit (76). Both gradual and abrupt timing characteristics of the channel (26) are absorbed by the variable timing circuits (68, 76).

Title: Method and device for generation of clock signals
Inventor: ERIKSSON KARL
IPC: H04N21/43
Filed: 1994-11-24
Abstract: A method and a device for regenerating clock rate information in which data is intermediately stored in a memory (1) to which the data is read at a first rate (C1) and out of which the data is read at a second rate (Cp). The difference (np, np') between two levels (N/N', P) of the amount of data stored in the memory (1) is determined, after which the difference is compared with a reference value (10). The result from the comparison affects the second rate so that, at subsequent measurements of the difference, the difference between it and the reference value shall decrease.

IPC: A61F2/958
Filed: 1995-01-24
Abstract: A method and apparatus for delivering occluding agents through an opening in a blood vessel wall and into an aneurysm chamber or a branch vessel to occlude same employs a balloon catheter, inflating the balloon to seal the blood vessel lumen around the vessel opening, and delivering the occluding agent through the opening.  The inflation of the balloon positions an exit port coupled to a delivery lumen laterally in the vessel in alignment with the vessel opening for delivering of the occluding agent therethrough. The inflated balloon maintains the occluding agent therein until it forms an occluding cast either in response to exposure to body fluids or radiation emitted from the catheter.  The balloon may be shaped to form a blood perfusion passage and may be advanced over a guide wire. The distal catheter end may be rotated to align the delivery exit port with the aneurysm or branch vessel opening.  More than one delivery exit port and associated lumen may be provided for venting during delivery and/or for the delivery of a two component occluding agent. Alternatively mechanical thrombus forming devices may be delivered thereby into the aneurysm chamber or branch vessel to occlude it.

Title: System for presbyopia treatment
Inventor: RUIZ LUIS ANTONIO
IPC: A61F9/01
Filed: 1995-06-28
Abstract: A process for surgically correcting presbyopia includes anesthetizing a patient and marking a portion of an eye of the patient which is to be ablated.  At least a portion of the cornea is resected to expose the corneal stroma.  An annular portion of the corneal stroma is then ablated using radiation from a laser beam.  After ablation, the cornea is repositioned onto the eye.      The cornea may be resected such that a portion of the cornea remains intact, and is folded back to expose the corneal stroma.          Alternatively, a complete disk of the cornea may be removed from the eye, to thereby expose the corneal stroma.  After exposure but before ablating, the corneal stroma should be dried to prevent uneven ablation which may occur if fluids are present on the stroma.  The laser beam may be directed in a circular fashion until an annular ablation is formed, or a mask may be provided over a central area of the corneal stroma.  To prevent edema, the ablated portion should be cleaned by brushing and irrigating.  A system for surgically performing the presbyopia correction process also is described.  This system includes a marker, a resector such as an automatic corneal shaper, and a laser for ablating the corneal stroma.

Abstract: An objective and non-destructive test of the fused joints in an armature, that can be used on every armature being manufactured on an armature manufacturing line, as well as apparatus for performing that test, are provided. The armature is immersed in an acoustic coupling medium. Acoustic pulses, preferably ultrasonic pulses, are beamed onto the commutator tang/wire interface region of a commutator tang/bar fused joint or the fused joint itself and an acoustic signature is measured.
