Patent CA-2047905-A1 (CA)
Inventor: SUZUKI HIROSHI
IPC: G02F1/133
Filed: 1991-07-25
Abstract: The  present  invention  relates  to  a  matrix  type  liquid crystal display in which a single pixel is comprised of four adjacent  subpixels.   Sixteen  level  monochrome  display  is performed  by  an  areal  gradation  of  the  four  adjacent subpixels.  One method for removing flicker of the display is practiced by inverting the polarity of column signals applied to column lines every two alternate lines and by inverting the polarity of  column  signals  applied to the column  lines  every  two  row  alternate  lines.   The  other method for removing flicker of the display is practiced by inverting the polarity of column signals applied to column lines  every  two  alternate  lines  and  by  alternately connecting each two adjacent subpixels of said subpixels in one column between two adjacent column conductors to said two adjacent column conductors.

Title: Ring-type antenna, with reduced center working frequency, and vehicle equipped with at least one such antenna
Inventor: DOUSSOT MICHEL
IPC: H01Q13/18
Filed: 1991-12-13
Abstract: ABSTRACT OF THE DISCLOSURE The  disclosure  relates  to  ring-type  antennas, namely antennas comprising a ground plane, a conductive flat ring parallel to the ground plane and a dielectric layer separating the ring from the ground plane.  These antennas work in a standard  way in TM02 or TM11 mode.          The antenna is designed to work with a configuration of the electromagnetic  field  between the  ring  and  the ground plane  according to  the TM01  mode but  with  a working frequency that  is reduced as  compared with  a standard  working  frequency.  For  this  purpose,  the conditions of propagation of the waves between the ring and the ground plane  are modified by the  introduction of a  short-circuit  plane  between one  of  the  rims, namely the internal  or the external  rim, of the  ring and the ground plane.  The center working frequency  is thus reduced by  a ratio  of 3  to 4  as compared  with standard working in TM02 mode. The disclosed device can be applied to  antennas for radio- communications  made, for example, from aircraft.
