Title: Video memory arrangement
Inventor: KOPPELMANS JOHANNES FRANCISCUS
IPC: G11C7/10
Filed: 1995-08-10
Granted: 1999-10-12
Abstract: By providing a digital video memory arrangement with first and second address generating means, digital video signals can be written at  a  first  location  of  a  non-mechanical  memory  and  (almost) immediately read out  from a second location of the non-mechanical memory, with the reading out both being capable of featuring backward and forward jumps. As a consequence of a coupling between the first and the second address generating means it becomes impossible to, on the  one hand,  unjustly pass with jumping  in the read  signal  the running or stopped write signal and, on the other hand, unjustly pass with the running read signal the stopped write signal. To this end the second address generating means dispose over determining means  for determining, in response to at least the write signal and the read signal, a permitted address jump.

Title: Illumination device and liquid crystal display apparatus including same
Inventor: KANDA TOSHIYUKI
IPC: G02B6/00
Filed: 1995-12-15
Granted: 2000-04-11
Abstract: An illumination device includes a plurality of linear light sources disposed with a prescribed spacing therebetween, a light guide means disposed between or among the linear light sources, and a reflection means disposed behind the light guide means so that light issued from the linear light sources is transmitted through the light guide means and reflected by the reflection means to be emitted in a direction forward from the light guide means.          Further, a luminance distribution-adjusting means for reflecting light transmitted through the light guide means is disposed along the light guide means in a distribution density which varies continuously at a changing rate free from discontinuity so as to adjust the luminance distribution of the light emitted in the direction forward from the light guide means.  The illumination device may be suitably used as a backlight behind a liquid crystal panel to provide a liquid crystal display apparatus having improved display qualities.

Abstract: A paper towel dispenser of the type dispensing towelling spirally from the center of a coreless roll of towelling while the roll stands upright. The dispenser is a knockdown dispenser having a separate base, a first casing part, and a second casing part. The dispenser can be shipped with the parts  disassembled to save space and assembled onsite by connecting the base to the first casing part and then pivotally connecting the second casing part to the base. The roll of towelling sits on the base and the casing parts form an enclosure about the roll. The dispenser has a dispensing nozzle in the base through which the paper towelling is dispensed. An access opening is provided in the wall of the nozzle to make it easier to thread the towelling through the nozzle when loading a new roll of towelling in the dispenser. A dispensing ring may be provided in the bottom of the nozzle through which the towelling is dispensed. The ring can be replaced if worn or if a different size of dispensing opening is needed in the nozzle.

Granted: 1999-12-07
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which runs a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.

Title: Virtual retinal display with fiber optic point source
Inventor: TIDWELL MICHAEL R
IPC: H04N9/31
Filed: 1996-04-19
Granted: 2006-11-28
Abstract: A virtual retinal display utilizes photon generation and manipulation to create a panoramic, high resolution, color virtual image that is projected directly onto the retina of the eye. The virtual retinal display includes a source of photons, the photons being modulated with video information and scanned by a scanning system in a raster type of pattern directly onto the retina of the user's eye. A single, monofilament optical fiber (300) of very small diameter couples light from the photon generator (308, 314) to the scanning system (16) so as to provide to the scanning system a point source of light at the fiber's exit aperture (306). The photon generator may utilize coherent or non-coherent light. Further, the photon generator may utilize color light emitters so as to scan a colored virtual image directly onto the retina of the user's eye.

Abstract: La présente invention concerne un procédé et un système (110) permettant de surveiller un processus industriel ainsi qu'un capteur (104). Selon ce procédé et ce système, on détermine un nombre minimum de paires de capteurs nécessaires au test du processus industriel et on définit le capteur (104) servant à évaluer l'état de fonctionnement des deux capteurs. Après prise en compte de deux signaux associés à une même variable physique, on obtient une fonction différentielle par détermination de la différence arithmétique entre les paires de signaux échelonnés dans le temps. La fonction différentielle soumise à transformation du domaine de fréquence donne des modes de Fourier décrivant une fonction composite. Disposant d'une fonction résiduelle après avoir soustrait la fonction composite de la fonction différentielle, on soumet la fonction résiduelle (exempte de bruit non blanc) à une analyse par test des ratios statistiques de probabilités.

Abstract: A menu board system comprising a support structure, made of magnetically attractable material, and various strips indicating, for instance, products sold and magnetic elements indicating prices at which products are sold. Once all the elements and strips are in place on the support structure, the front surface of the menu board seems flat and continuous as all pieces are cut to fit perfectly in an edge-to-edge pattern. The price elements are easily removed by simply pressing an element's bottom portion allowing the top portion to lift off the support structure. The ease of removal is caused by a magnet fixed only to the top portion of the back surface of the price element. The bottom edge of the magnet acts as a fulcrum point and the back surface of the element left uncovered is simply pushed into the support structure, permitting the top portion of the element to be grasped.

Title: Switch integrated controller for energizing an external electrical device
Inventor: TODOKORO TAKAYUKI
IPC: G04C23/02
Filed: 1998-10-07
Granted: 2002-09-17
Abstract: A switch integrated controller capable of giving a wide variety of controllers at a reduced cost. The controller has a casing composed of a controller module and a terminal module which are separately formed from each other and detachably connected to each other. The controller module has an entry section for receiving a specific external condition and a signal generating section which generates a trigger signal when the specific condition is met by a predetermined reference. The terminal module includes at least one pair of terminals which are adapted to be connected through wires to the external electrical device and an associated external power source and further includes a relay switch which is connected between the terminals for selectively connecting and disconnecting the electric device to and from the electrical power source in response to the trigger signal. Thus, the terminal module including the relay switch can be made common to different kinds of the controller modules and can be assembled with the controller module into a single unit only at an expense of simple mechanical connection between enclosures of the respective modules and electrical connection between the switch relays and the signal generating section. With this result, a wide variety of controller units of different functions can be fabricated at a reduced cost.
