Title: Method of Selecting the Most Desirable Code Search Mode in a Pager in the Case of Frame Async
Inventor: KURAMATSU HIROYASU
IPC: H04L7/033
Filed: 1993-11-03
Abstract: In the event that a radio pager falls into frame async while receiving information, an appropriate code search mode is desirably selected. Firstly, a controller of the pager checks to see if a bit sync indicating signal obtained from a bit synchronizer demonstrates bit sync. If the bit sync indicating signal indicates bit synchronization, the controller selects an operation mode for searching for synchronization code (SC). On the other hand, if the bit sync indicating signal indicates bit async, the controller selects a preamble code search mode. Accordingly, in the case where the pager becomes out of synchronism and immediately thereafter restores same during information acquisition, the pager is able to successfully obtain subsequent information by means of very simplified arrangement.

Title: Multi-user digital laser imaging system
Inventor: SCHUBERT PAUL CHARLES
IPC: H04N1/23
Filed: 1993-11-03
Abstract: ABSTRACT OF THE DISCLOSURE      A multi-user digital laser imaging system for imaging film from bar coded cartridges as a function of image values representative of the images to be printed.   The imaging  system  includes  memory  for  storing  transfer functions and film models for each of several users.  The transfer functions characterize the relationships between image  values  and  expected  imaged  film  transmittance quantities.  The film models characterize the relationship between the transmittance quantities and laser drive values that will provide the appropriate film exposure.  An image management subsystem generates lookup tables characterizing the relationship between image values and laser drive values on the basis of user-selected transfer functions and film models selected by the system through the use of film identification information read from the bar code.  During imaging operations the image management subsystem accesses the lookup tables as a function of the image values to obtain the appropriate laser drive values.  The transfer functions can be modified to accommodate user preferences. Test  wedge  calibration  procedures  are  periodically implemented  to  correlate  the  film models  to measured sensitometric characteristics.  Density patch calibration procedures are performed during each imaging operation to correct for drifts caused by the film developing subsystem.
