Abstract: L'invention se rapporte à un procédé et à un appareil pour écarter mécaniquement la paroi abdominale (W) des organes abdominaux sous-jacents (C) pour permettre une opération de chirurgie péritonéoscopique sans insufflation. Dans ce procédé, on pratique une petite incinsion par laquelle on introduit dans la cavité abdominale un dispositif expansible (74) en positon repliée, lequel est ensuite déployé pour venir en prise avec une zone extensible de la paroi abdominale. Une force de soulèvement est ensuite appliquée au dispositif pour permettre l'écartement du péritoine. Ce dispositif peut se présenter sous la forme de tiges mécaniques ou de bras et/ou de ballons. Dans les modes de réalisation sous la forme de ballons, la force de soulèvement peut être appliquée à l'extérieur de la cavité abdominale ou à l'intérieur de la cavité par gonflage du ballon. Dans certaines variantes, les ballons ont une structure annulaire ou en U et comportent une membrane pour recouvrir de champs stériles les organes internes et/ou un ballon central destiné à permettre une expansion latérale. Les ballons peuvent être équipés d'un endoscope interne pour la visualisation. L'invention décrit également un procédé pour l'extraction de la vésicule biliaire par voie péritonéoscopique, soit à l'intérieur soit à l'extérieur des ballons. Une aiguille (144) est prévue pour percer et drainer la vésicule biliaire par voie péritonéoscopique. L'aiguille porte un ballon (146) qui est conçu gonflable pour s'accrocher à la vésicule biliaire, afin de permettre son écartement et son extracion.

Abstract: An improved tonometer (1) is disclosed having pachymetric means (44, 46, 48) for measuring a patient's corneal thickness to allow for correction of the intraocular pressure measurement where the corneal thickness measurement deviates from a calibration mean corneal thickness. In a preferred embodiment, a single light source (50) is pulsed just prior to intraocular pressure measurement to illuminate a central section, and a pair of lateral light detector arrays (34a, 34b) are arranged to obliquely image the corneal section and generate signals which may be processed by a CPU (48) to produce a corneal thickness measurement. If the corneal thickness measurement deviates from the calibration mean corneal thickness, the CPU calculates a thickness corrected intraocular pressure measurement. The intraocular pressure measurement, corneal thickness measurement, and/or corrected intraocular pressure measurement may then be reported by reporting means (64).

Abstract: A non-contact inspection system capable of evaluating spatial form parameters of a workpiece (22) to provide 100% inspection of parts (22) in production. During production, it is not uncommon for one or more process to fail to produce the desired geometry of the part. The occurrence of such defects is not adequately monitored through other quality assurance processes. The system of the present invention causes parts (22) to be sequentially loaded onto an inclined track (16) where they pass through a test section (18). The test section (18) includes a length detection array (40) for measuring the length of the workpiece (22), which includes a source (43) generating a sheet of light oriented in the longitudinal direction of the workpiece (22). The profile of the parts (22) are evaluated by one or more light sources also creating a sheet of light oriented transverse to the longitudinal axis of the parts (22). Single channel photodetectors are provided for each of the sources which provides an analog output of the extent to which each sheet of light is occluded by the part (22). These outputs are analyzed through appropriate signal processing hardware and software to generate length and profile data related to the workpiece geometry.

Title: Automated self-cleaning litter box for cats
Inventor: WATERS MICHAEL A
IPC: A01K1/01

Granted: 2004-05-25
Abstract: An improved automated self-cleaning litter box for cats, of the kind having a housing defining an upwardly open chamber for storage of a supply of cat litter, accessible to a cat and having path members on opposed side walls defining a comb path from one end of the chamber to the other. A comb, normally stored at the comb storage end of the chamber, is driven forward along the path to the discharge end of the chamber and back to its original storage position. As the comb traverses the chamber forwardly it engages any clumps of waste in the litter and carries them to a disposal receptacle at the discharge end of the chamber. The improvement includes a sensor for sensing the presence of a cat in the litter chamber; a photo electric sensor is preferred, but an infra red, weight, or even an audible sensor can be used. A delay device actuates the comb drive a predetermined time interval after the sensor ceases to sense the presence of a cat in the litter chamber. In the improved construction the comb path includes multi-perforate track members on opposite sides of the litter chamber; those tracks are engaged by rotatable drive wheels connected to the comb. The comb drive includes a reversible electric motor, mounted on the same carriage as the comb. A transparent, biodegradable receptacle is used; alarms for a full receptacle and for an insufficient litter supply are provided.

Abstract: An optical sight (30) is affixed to a rail (26) on a receiver (22) of a weapon (20) by a torque-limiting weapon mount (40). Force is applied to clamp the optical sight (30) to the rail (26) by the relative movement of two inclined ramps (58, 72), one on a rotating knob (44) and the other on a nut (42)whose turning generates the clamping force. The torque, and thence the force, that can be applied in attaching the optical sight (30) is limited by the selection of a spring (102) and by steps (64, 78) at the ends of the two inclined ramps (58, 72) that prevent a clamping force greater than that permitted by the spring(102) force when the knob (44) is turned.

Abstract: Apparatus (10) and a method for vitrifying hazardous waste includes a melting vessel (12) in which a stirrer (38) mixes hazardous waste and any other necessary components for forming a glassy mixture upon heating while an electrical current is applied across the melting vessel and the stirrer to provide electrical current flow, and a metallic containment vessel (46) of the apparatus receives the melting vessel so as to receive and contain any material that exits the melting vessel upon failure. Any failure of the melting vessel (12) is detected by a sensor (48). The containment vessel (46) is preferably hermetically sealed around the melting vessel (12) to contain gases as well as any melted material received from the failed melting vessel (12). The sensing of the failure can be either by a pressure change in the hermetically sealed chamber (58) or by sensing of the presence of material received by the containment vessel (46) from the failed melting vessel (12) such as by an electrical circuit type detection.
