Abstract: A method of reading data represented by a marking including at least one periodic nanostructure, the marking representing data using a polarisation property of the periodic nanostructure. The method includes detecting polarised electromagnetic radiation reflected from or transmitted by the nanostructure, and determining the data represented by the marking from the detected polarised electromagnetic radiation, wherein the method further includes applying polarised electromagnetic radiation to the nanostructure, and/or the detecting is performed using a polarisation-sensitive detector apparatus.

Abstract: A method for designing a computational device or circuit having one or more desired characteristics, preferably input and/or output characteristics. The method involves using an inner, iterative search that is preferably used within one or more genetic operators. As a first step, one of a population of computational circuits or devices is selected. Once this is done a point in the selected circuit or device is chosen and characterised in terms of the circuit inputs and/or outputs. A parameter or characteristic associated with the selected point is then modified and the point is re-characterised. This is repeated to provide characterisations for a plurality of modified versions of the circuit. Then, the circuit that has characteristics closest to the desired characteristics is identified and added to the population of circuits, and the inner search loop is repeated for another one of the population.

Abstract: A safety-related control system (SRCS) designed to safeguard personnel operating hazardous production equipment. The SRCS integrates the safety-related part of a machine into one homogenous system for the purpose of increasing safety. In so doing, the SRCS monitors the machine, the operator, and itself for safe operation. The SRCS utilizes a non-material barrier to sense the intrusion of a person's body into a hazardous area of a machine. The SRCS uses machine feedback and/or operator interface to determine whether a hazardous condition is present. If such condition is present, the hazard is rendered harmless by the time the intruding body member can reach the potential danger area. The system includes separable means for stopping motion of the moving parts of the equipment, starting movement of the movable parts, and detecting faults in sections of the system.

Abstract: A photodetection system and related circuitry designed to sense the intrusion of an opaque object in a light plane. Upon sensing the intrusion, the system quickly initiates a machine-stopping sequence prior to the opaque object coming into contact with the machine while that machine is operating. The system comprises a SYSTEM microcontroller and a WATCHDOG microcontroller, both of which operate an output control device of the light curtain switch of the invention, wherein the output control device comprises a plurality of electromechanical relays. Both microcontrollers also perform system hardware and software integrity checks. Furthermore, the WATCHDOG microcontroller evaluates the performance of the SYSTEM microcontroller by transmitting a false intrusion signal to a photosource, determining whether the false signal has been detected, and then verifying that the SYSTEM microcontroller has initiated the machine-stopping sequence.

Abstract: A method and apparatus are disclosed for pneumatically controlling the velocity of flow of liquid metal from a tundish into a continuous casting machine through a nozzle. A chamber encloses the nozzle outlet, and at least a portion of the continuous casting machine, and a pressurized gas is supplied to the chamber. The flow velocity of the liquid metal at the nozzle outlet is controlled by controlling the gas pressure in the chamber in response to the level of the liquid metal in the tundish, and the measured atmospheric pressure acting on the liquid metal in the tundish.

Abstract: This invention relates to a method for administering drugs. In particular a lipophilic drug is solubilized by a food, such as chocolate, and admixed with an oil-based carrier. The lipid soluble drug is thus conveyed to the gastrointestinal tract. Because this type of food is digested readily, the drug is absorbed as intended, and the dose is not subject to day-to-day variations.

Abstract: Disclosed are a system and a method useful in fields such as architecture, space planning, interior design and corporate facility management, for efficiently designing and allocating space to the various subdivisions of an organization. Manipulation of colors is used in addition to numerical values to allow the user to determine at a glance the relative priorities of various departments and the affinities between pairs of departments at various stages of the space allocation process, and thereby speed the process and reduce the chance for errors.

Abstract: Elongated members of reactive metals and alloys thereof, for example, uranium and alloys thereof, are cast from a crucible containing the molten metal blanketed with an inert gas and non-reactive prepared molten slag, directly into a mould protruding from the crucible. The cast metal is spray cooled with inert gas, which may be liquefied, as it emerges from an outlet end of the mould and is pulled, for example by rollers, into and possibly through an inert gas flushed container directly connected to the mould outlet end.
