Abstract: In a rule-driven method and system for editing a physical integrated circuit layout formed from a plurality of working shapes, a desired one of the working shapes is initially created on a computer monitor. After calculating a width value associated with the desired one of the working shapes, the width value is verified to determine if it violates a minimum distance as defined by relevant design rules of an applied fabrication technology. Automatic adjustment of the geometry of the desired one of the working shapes to comply with the relevant design rules is subsequently performed upon verification that the width value violates the minimum distance.

Abstract: A portable alarm apparatus for use by a sudden heart attack patient is provided that is characterized by a housing part connected to a suspension member for hanging around a patient's neck. Sensors are disposed on the suspension member and connected to an extending lead, enabling the sensors to contact respective pulse spots on the patient's neck, due to the downward force resulting from gravity acting on the housing part. The sensors detect the pulse signals in an artery in the user's neck corresponding to heartbeats and output an electrical signal for input to a control circuit disposed in the housing part for storage, display and generation of a warning alarm.

Abstract: A tow of continuous filaments is fed by aspiration into a stream of compressible fluid. The stream containing the filaments is directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the compressible fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass of the tow and emerge from the chamber in crimped form.

Abstract: Continuous filaments are fed by aspiration into a stream of heated fluid. The filaments are then contacted with at least a second stream of heated fluid to increase the temperature of the filaments. The combined streams of fluid containing the filaments are directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass thereof and emerge from the chamber in crimped form.

Abstract: Continuous filaments, e.g. in the form of yarn, are fed by aspiration into a stream of heated fluid. The stream containing the filaments is directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass thereof producing crimps therein. One or more streams of heated fluid are then contacted with the mass of filaments to set the crimps. The crimped filaments emerge from the chamber through an outlet opening therein.
