Filed: 1999-06-18
Abstract: The invention relates to a method, device (4) and a system (1) for detecting  and processing viewing data which concerns the visual behaviour of users, wh en viewing video information. Said device and system determine information concerning the lines of vision of a user in relation to the viewed video information by the direct projection of video information onto the user's retina (51) and by the determination of the current positions of the user's eye. These positions are transmitted via a telecommunication network (3) to a central unit (2) for further processing. Said further processing involves comparing the current eye positions with predetermined values and as a resul t of this comparison, triggering predetermined events and/or storing the aforementioned viewing data in the central unit (2), for example, for subsequent statistical evaluation.

Title: Packaged soap bar
Inventor: VAN GORDON TODD
IPC: B65D65/40
Filed: 2000-06-07
Abstract: Soap bars can be effectively packaged in substantially transparent materials so that the soap bar can be seen through the packaging material. This is particularly useful with decorative colored translucent soap bars. The soap bars first are at least partially enveloped in a first relatively thick and stiff substantially transparent film and then fully enveloped in a second relatively thin substantially transparent film. The soap bars are generally rectangular but with rounded edges and a shape that tapers in cross-section from a midpoint of the soap bar to the ends. The first film forms a substantially rectangular cylinder which envelops about 95 % to about 105 % of the soap bar. This rectangular cylinder is open at each end.  The second film fully envelops the soap bar. The end package provides a soap bar maintained within a rectangular cylinder with a low fragrance loss and a moisture transmissivity of less than about 3gm/m2/day.

Patent CA-2379749-A1 (CA)
Inventor: ALBAGLI DAVID
IPC: C12Q1/68
Filed: 2000-06-30
Abstract: Multiplexed determinations of large numbers of events are achieved in an accurate and simple manner by using a combination of different oligonucleotides, which serve for both capture and release from a support and strand displacement oligonucleotides for sequential release of groups of oligonucleotides. Also included, as part of the oligonucleotide reagents may be identifiers, which serve to identify a particular characteristic. The method is illustrated using primers for initiation of chain extension joined to or serving as the capture/release sequence, where the extended primer has an identifier. After extending the primer, the extended primers are captured and independently released and the released extended primers assayed. The subject method finds application for nucleic acid sequence determinations, single nucleotide polymorphism determinations, identification of nucleic acid fragments, and the like.

Inventor: SIMON CHRISTIAN
IPC: G06V10/422
Filed: 2002-07-26
Abstract: A method of pattern matching for recognition of objects within an image, uses a model defined by a set of one or more model primitives representative of large scale structures of an archetype. The image is analyzed to derive at least one target primitive representative of a large scale structure of the image. A basis is derived from at least one of the target primitives, and each of the target primitives represented as invariants in the derived basis. For each target primitive, any model primitives that at least partially match the target primitive are identified. Each identified model primitive is then processed to calculate a figure of merit indicative of a degree of correspondence between the target primitive and the model primitive. In some embodiments, the figure of merit is an Orthogonal projection between the target and model primitives, which is and accumulated for each model basis.

IPC: F23D3/26
Filed: 2002-09-04
Abstract: A freestanding candle has a flame-resistant sheet adhered to a wick support and to a fuel body in a location proximate to the lower end of a wick. The sheet reduces the risk of fire hazards that arise during the later stages of candle burning, which are characterized by a thin candle floor and a pool of liquid fuel surrounding the wick support.  The wick support is made longer and sealingly adhered to the sheet to further reduce the risk of fire hazards. The structural combination of the wick support, the sealant, and the sheet facilitates even burning during the life of the candle and self extinguishment of the flame at the end stage of burning.

Title: Method of monitoring animal feeding behavior
Inventor: HUISMA CAMIEL
IPC: A01K7/02
Filed: 2001-03-16
Abstract: A system and method having a plurality of antennas located at selected spaced intervals along an elongate feed or drinking trough. Each animal, to be monitored, is equipped with a passive transponder having a unique identification code. An electronic control system transmits an electronic signal sequentially to each one of the plurality of antennas such that each activated antenna emits a signal and, any passive transponder sufficiently adjacent to the activated antenna, receives the signal and generates a return electronic signal which is sent to the activated antenna. More specifically, a system, which is capable of being used with multiple transponders to monitor the feeding and drinking behavior of animals in order to predict a variety of conditions relating to health, productivity and quality. A computer, coupled to the plurality of antennas, receives a return signal from the passive transponder and generates preliminary results concerning an animal behavior, which effects animal consumption activity. Finally, a modification factor, incorporated in the computer, modifies the preliminary results to generate a final result that predicts, with a level of predictability, the animal behavior which effects the consumption activity monitored. A chalk powder ejector system visibly marks animals identified by the computer, coupled to the plurality of antennas that require intervention.  At least one medication container is connected to a water supply conduit for dispensing a desired medication to the water supplied by the water supply conduit, and a control valve is coupled to the computer to control operation of the control valve and facilitated automatic administering of the medication into the water supply conduit. A weighing mechanism is also provided for periodically weighing animals.

Title: A robust hydrodynamic brush seal
Inventor: JUSTAK JOHN F
IPC: F16J15/32
Filed: 2001-04-03
Abstract: A brush seal (10) for sealing a circumferential gap between two relatively rotating machine components, e.g. the rotor (14) or shaft and stator (12) of a fluid flow machine, such as a gas turbine engine. One end of a plurality of seal bristles (16) is fixed in an annular shape and are mounted to the stator, and their opposite ends are attached to a number of individual shoes (24) located at the rotor. The shoes function very similarly to that of a tilting pad bearing shoe. Prior to shaft (14) rotation, the shoes are in contact with the rotor surface with preferably the leading edge (26) of each shoe set to have less contact than the trailing edge (28) of the shoe. As such, when the rotor begins to rotate, a hydrodynamic wedge is created which lifts the shoe slightly off the surface of the shaft allowing the shoe to effectively "float" over the shaft at a design gap.

Abstract: A bulk vending machine provides a dispensing conduit having a revolving mouth that floats on top of a heap of articles in the product bin. The mouth is movable between a horizontal orientation, in which the mouth can scoop articles off of the surface of the heap, and a vertical orientation in which a throat of the dispensing conduit opens to allow an article which has been scooped into the mouth to fall through the dispensing chute. Revolution of the dispensing conduit by turning the handle causes the mouth to revolve around the heap of articles, scooping up one or more articles in its path. The mouth preferably has three operative positions:  a capturing position, an intermediate position in which the article falls into the mouth, and a dispensing position. A baffle plate having ramped trailing and leading edges revolves with the head and allows the head to float on top of the heap of articles.
