Title: Liquid crystal shutter system for stereoscopic and other applications
Inventor: LIPTON LENNY
IPC: H04N13/00
Filed: 1990-06-01
Abstract: ABSTRACT OF THE DISCLOSURE     A liquid crystal shutter system for selecting fields of a field-sequential image, by transmitting the field-sequential image, with a synchronization signal, to one or more remote liquid crystal cell shutter assemblies. Each shutter assembly transmits selected fields of the field-sequential image in response to a drive signal, and includes a drive circuit for receiving the synchronization signal and generating each drive signal in response to the synchronization signal so that each drive signal has transitions synchronized with image fields. The drive circuit is capable of rapidly processing short duration synchronization signals with very low power consumption. In one embodiment, two liquid crystal cell assemblies are mounted in an eyeglass frame and used as a wireless selection device for a field-sequential stereoscopic image. Preferably, the invention includes a synchronization signal receiver having a narrow angular reception range so that the receiver is sensitive to only one synchronization signal at a time, so that the invention may be employed to view several monitors without interference between different synchronization signals from the different monitors. Preferably, the inventive shutter assemblies are capable of operating in a non-occluding state, and each inventive shutter assembly may conveniently be switched between a state suitable for stereoscopic viewing and a non-occluding state suitable for viewing a non-stereoscopic image.

Title: Percutaneous lockable sleeve catheter
Inventor: OSBORNE THOMAS A
IPC: A61M25/00
Filed: 1991-02-19
Abstract: A lockable sleeve drainage catheter is disclosed for percutaneous insertion into a patient and drainage of fluid therefrom. The drainage catheter includes a flexible distal end that is preformed for retaining the distal end of the catheter that is inserted in the patient. For insertion, the distal end is straightened with the use of a stiffening cannula that is inserted through the hollow passageway of the catheter. When the catheter is inserted in the patient, the stiffening cannula is removed, and a flexible tension member positioned within the passageway of the catheter is drawn to position the distal end in the desired retention configuration. A lockable sleeve positioned at the proximal end of the catheter draws the flexible tension member through the passageway of the elongated member tube to position the distal end in the retention configuration. The catheter also includes a locking collar at the proximal end of the elongated member tube having an annular recess formed therein. The distal end of the lockable sleeve includes an annular step for engaging the recess of the collar and lacking the sleeve in a fixed position relative to the elongated member tube of the catheter. When fully extended and locked, the sleeve and elongated member form a fluid tight interconnection. A Luer lock connector is affixed to the proximal end of the sleeve for connection to a drainage collection system.

Abstract: CONTROL SYSTEM FOR FLUE GAS CONDITIONING               ABSTRACT OF THE DISCLOSURE        The  volumetric  flow rate for the addition of a   flue  gas  conditioning  agent,  such  as  sulfur trioxide,   is established   by   maintaining   the derivative  of  the  electrostatic precipitator power with  respect  to  flow  rate  within  a  preselected operating  range.  The derivative of the precipitator power  with respect to time and the derivative of the flow  rate  with  respect  to  time are measured, and then  the  derivatives  are  divided to determine the derivative  of  precipitator  power  with  respect to flow  rate.  This calculated value is compared with a preselected  operating  range. If  the  calculated value  is  greater  than  the  preselected  operating range,  the  flow  rate  of the conditioning agent is increased.   If the calculated value is less than the preselected   operating   range,  the  flow  rate  is reduced,  until  a steady state calculated derivative value within the operating range is reached.
