Abstract: A light addressed liquid crystal light valve has two optically different states switchable therebetween by bias voltage in response to incident light. A ferroelectric liquid crystal layer (10; 110) is sandwitched by a pair of front and rear alignment layers (7a, 7b; 107a, 107b) to establish the two stable states in the ferroelectric liquid crystal layer. 
A front electrode layer is disposed on the front alignment layer. A dielectric mirror (6; 106) is disposed on the rear alignment layer (7a; 107a). A photoconductive layer (4; 104) is disposed on the dielectric mirror and responsive to the incident light incident from the rear face of light valve to increase its electroconductivity. A barrier metal layer (13, 105) is disposed on the photoconductive layer and forms a Schottky diode by combining with the photoconductive layer. A rear electrode is disposed on the barrier metal layer and is divided into a plurality of sub-electrodes to apply various bias voltage on the ferroelectric liquid crystal layer to thereby control a light writing sensitivity of the light valve according to the intensity distribution of a writing light.

Abstract: Direct overwriting of encoded data along a track in a magneto-optic recording medium (10) is described. A laser (24) beam, not modulated by data, is directed at the active side of the medium to locally heat the width of one track for conditioning it for direct overwriting. A magnetic head (30) comprising an inductor and a capacitance in parallel with the inductor is movable in an appropriate manner to a selectable track. While the head is in alignment with the beam, current of a preselected polarity is supplied from a current source to the inductor. The current source is disconnected to reverse the field of the magnetic head by reciprocation of energy between the inductor and capacitance. Once the magnetic field is reversed, current is supplied to the inductor for maintaining the field until the next field reversal, the reversal times being determined by the data to be written. 
     For pulse width modulation recording, the current normally supplied to the inductor is of one polarity and that supplied following the reversal is of opposite polarity; whereas for pulse position modulation recording, the current supplied to the inductor is of the same polarity before and after reversal. 
     The inductor is preferably mounted for movement on a voice coil actuator and thereby maintained at a predetermined fixed distance from the medium.

Abstract: The present invention is directed to the grouping of contiguous floors in a building into sectors. According to the present invention, historical information regarding the number of passengers arriving at each floor is obtained and used to predict the number of passengers to be arriving at each of the floors. By summing the predicted traffic per floor and dividing by the number of sectors to be formed, average traffic per sector can be determined. In the preferred embodiment, sectors are formed, starting from the first floor above the lobby and continuing through to the top floor in the building, by selecting a set of contiguous floors for each sector such that the predicted traffic for each sector is less than a predetermined threshold. Specifically, if the predicted traffic for a selectable next contiguous floor, added to the predicted traffic for all contiguous floors already selected for the sector, is less than the predetermined threshold, the selectable floor is included in the sector. Otherwise, another sector is begun with the selectable floor as the bottom floor in the other sector. In the preferred embodiment, the predetermined threshold is based on the determined average traffic per sector. In another aspect of the present invention, the frequency of service elevator cars to each sector is variable. The traffic volume for each formed sector is determined and compared with the determined average traffic per sector. The frequency of service of elevator cars to each sector is variable, based on this comparison. Thus, sectors having a larger traffic volume are serviced more often, relative to sectors having a smaller traffic volume.
