Patent EP-0378293-A3 (EP)
Title: Liquid crystal display device and its driving method
IPC: G02F1/141
Filed: 1990-01-03
Abstract: A liquid crystal display device and its driving 
method of the present invention have a voltage application 
scheme to control a stable condition of a gap between 
pixels, by applying a voltage to a liquid crystal panel (1) in 
which ferroelectric liquid crystal is sandwiched between 
substrates (2, 3) each having a plurality of electrodes (4, 5). It is 
possible to implement the black matrix conditions with a 
simple configuration without a light shielding layer by 
controlling the stable condition of the gap, to display a 
grey tone with a combination of pixels and a gap, or to 
raise the opening ratio by making the condition between 
adjacent pixels and a gap the same condition.

Title: Web material for web handling machine
IPC: B42D5/02
Filed: 1990-02-12
Abstract: A web of material adapted to be driven through a 
machine by sprocket wheels having projecting sprocket pins 
comprises a series of main sprocket holes (2) at standard 
half-inch pitch and a second sprocket hole (3) located mid­
way between each main sprocket hole. A set of radial cuts 
or lines of weakness (4-7) extend from each secondary 
sprocket hole so as to a define readily deformable zone (8) 
on each longitudinal side of each secondary sprocket hole 
and readily deformable zones (9) on each lateral side of 
each secondary sprocket hole. The readily deformable zones

encounter a sprocket hole located in the zone of but out of 
direct register with the secondary sprocket holes (3).
Patent EP-0392736-A3 (EP)
Title: Treadle assembly
IPC: G08G1/015
Filed: 1990-04-04
Abstract: A treadle assembly is provided comprising a resilient 
envelope adapted to be disposed in a roadway, and one or more 
flexible circuits disposed therein. Said flexible circuits 
each comprise an electrically conductive deformable 
elastomeric layer, a flexible spacer sheet having at least one 
opening therein and a contact means, said spacer sheet being 
interposed between the elastomeric layer and the contact 
layer. When pressure is applied, e.g. when a vehicle passes 
over the circuit, the elastomeric layer will deflect to engage 
the contact means through each of the openings in the spacer 
as the vehicle passes over that opening, forming a closed 
circuit. Due to the resiliently deformable nature of the 
elastomer, the elastomer will immediately return to its 
initial position when the weight of the vehicle is removed, 
reopening the circuit. In a preferred embodiment of the 
invention, the elastomeric layer, spacer, and contact layer 
are disposed within a substantially flat envelope, formed of 
superimposed sheets of a resilient flexible material which are 
joined at their edges. This envelope prevents attack by 
water, sand and road salts and provides support for the 
contact means.

Abstract: A digital camera having a camera body and a lens assembly
within an imaging unit which is rotatably connected to the
camera body. Rotation of the imaging unit containing the lens
assembly with respect to the position of the camera body
causes the flash within the camera body to follow the
direction at which the lens assembly is aimed. If the camera
has a self-portrait mode in which the lens assembly can be
aimed backwards at the user of the camera but the flash cannot
be aimed backwards due to constraints of the camera body or if
the flash cannot cover the complete angular range of the lens,
a mechanism is utilized to couple the movement of the lens and
the flash over a limited range of movement of the lens.
Springs, concentric gears attached by springs, or a clutch
mechanism may be utilized to selectively couple the flash with
the lens rotation. By separating the flash from the lens, the
red-eye phenomena will be reduced.
