Title: Electronic simulator of non-linear and active cochlear signal processing
Inventor: GOLDSTEIN JULIUS L
IPC: G10L25/75
Filed: 1993-11-01
Abstract: 2148453 9410820 PCTABScor01 A model simulating cochlear spectrum analysis (Fig. 3) is disclosed which includes a pair of matched all pole lattices interconnected by a plurality of tip couplers providing non-linear distributed bilateral signal processing. One of the lattices along with the tip couplers corresponds to the organ of Corti found in the cochlea and the second lattice corresponds to the basilar membrane also found in cochlea such that the model provides a striking resemblance in structure to the physical properties of the cochlea itself. With the cochlea model disclosed, distortion products and oto-acoustic emissions are simulated. An intermediate model (Fig.  10) is also disclosed which provides non-linear bilateral signal processing and additive directional wave amplification. The present invention also implements the cochlear model using analog electronic technology in closer agreement with the cellular biophysics of the human ear.

Title: Addressing ferroelectric liquid crystal displays
Inventor: HUGHES JONATHAN RENNIE
IPC: G02F1/133
Filed: 1994-04-08
Abstract: The invention concerns a surface stabilised ferroelectric liquid crystal (SSFLC) display devices. Displays are formed by cells containing a thin layer, e.g. 2 µm thick, of smectic liquid crystal material. The cell walls are surface treated and carry e.g. row and column electrodes forming an x,y matrix of addressable display elements or pixels.  These devices can show bistability and switch between their two stable state on application of a dc pulse of appropriate polarity, amplitude and width. In this invention the device is addressed by first preconditioning the liquid crystal material at each pixel by applying one of two different levels of ac bias, thereby changing the switching characteristics of the material, and second by switching with application of a switching pulse. This results in pixels that have received the first of the ac bias levels switching whilst the other pixels do not switch.  The two levels of ac bias may be applied e.g. by a combination of bipolar strobe pulses and two bipolar data waveforms applied in a multiplex addressing manner to the row and column electrodes. The subsequent switching pulse may be shared between row and column electrodes to give a resultant pulse of appropriate polarity, amplitude and width.
