Abstract: A data collection and management system designed for real-time monitoring of welding systems in refinery and petrochemical environments is disclosed. The system includes a data collection module integrated with sensors to automatically capture data from welding equipment (i.e., welder) using multiple protocols such as IoT and OPC. A database management module stores the data in a structured SQL database with indexing and search capabilities. A barcode generation and scanning module allows for quick data retrieval and updates by generating unique barcodes for welded components and documents. An AI module tracks equipment usage, efficiency, and downtime, predicting future maintenance needs and generating audit trails. A reporting module provides real-time visualization through interactive dashboards and generates automated reports for compliance and performance reviews.

Abstract: A nasal cannula system having nasal prongs with an ancillary delivery system for a treatment fluid into a patient wearing the nasal cannula without removing the cannula. The nasal prongs have parallel ports that fluidly connect the delivery system to the nasal ports on the nasal prongs. The delivery system provides the treatment fluid in an aerosolized form. This configuration combines the aerosolized treatment fluid with the air or other fluid ordinarily delivered by the nasal cannula. The system may also use airway tubes having a generally semi-circular cross-section with an internal rib extending the length of the tube. The semi-circular cross-section provides a flat exterior surface for abutment or contact with a patient's skin and the rib prevents pinching closure of the airway tube.

Abstract: A nasal cannula system for use in ventilator systems, particularly continuous positive airway pressure (CPAP) systems. The nasal cannula system has a nasal body with nare prongs that extend into a patient's nostrils when worn. The ventilator system includes a ventilator on an inhalation side and either a bubble chamber or a variable resistance valve on the exhalation side. The inhalation side may include a heater/humidifier in-line with the supply tube so as to treat the air before application. The airway tube may have a generally semi-circular cross-section so as to provide a flat exterior surface for abutment or contact with a patient's skin.

Abstract: A method of treating a subterranean formation penetrated by a well-bore, for example to facilitate fracturing of the formation, comprises the steps of: (i) selecting a treatment fluid comprising a diverting agent (A) in a flaked form, for example guar gum in a flaked form. (ii) introducing the treatment fluid into the subterranean formation via the well-bore to plug a region of the formation. Thereafter, the formation may be fractured or re-fractured.

Abstract: A gas supply tube for use in medical settings for the supply of gas to a patient. The airway tube has a generally semi-circular cross-section so as to provide a flat exterior surface for abutment or contact with a patient's skin. A nasal cannula system is constructed using the gas supply tube has a nasal body with cannula configured for insertion into nasal openings of a patient. The nasal body is connected to one or more gas supply or airway tubes. Both the nasal body and the airway tubes have a semi-circular cross-section. The other end of the airway tube(s) is connected to one or more supply adapters having ports matching the semi-circular cross-section. A surface retainer with a clamp having a semi-circular cross-section may adhere the airway tube to a patient's skin.

Abstract: A method and apparatus for protecting a low voltage system, such as an alarm system, is described. The method and apparatus includes power line surge protector and a plurality of low-voltage surge protectors housed within a common cabinet. The low-voltage surge protectors are mounted in connectors that provide physical support as well as electrical connections. These electrical connections are routed to a set of input and output terminals by a printed circuit board that also provides support for the connectors and terminals. The combination of power line surge protectors and low-voltage surge protectors may help reduce damage to equipment such as an alarm system during power surges, perhaps caused by electrical storms or heavy electrical equipment being operated nearby. Because of the radio frequency noise emanating from the power line and the power line surge protector, a shield is provided that reduces the amount of noise that is transferred to the low-voltage signal paths.

Abstract: A real time automatic headcount system is configured with a portable transmitter operated by a crisis coordinator and operable to output an alert signal which is received by a plurality of receivers which are coupled to respective persons associated with a crisis-event site. The receivers each generate an acknowledgement signal transmitted via a central processing unit to the transmitter. Upon receiving the acknowledgement signal, the central processing unit is operable to update a check list of all person associated with the crisis-event site, identify those who have not been accounted for and implement back up procedures for locating and accounting for the previously unaccounted for persons in real time.

Abstract: A rotational glider toy configured for producing bubbles during free flight. The toy includes a circular disc body having a plurality of bubble-forming apertures formed therein. A reservoir structure is coupled to a lower surface of the body and encloses a storage area. The reservoir structure includes a plurality of solution feed holes formed in a junction between the reservoir structure and the lower surface, said solution feed holes being in communication with the storage area. Bubble solution is inserted into the storage area through a capped filling hole therein. Centrifugal force during rotational movement of the toy operates to urge the bubble solution out of the feed holes such that it spreads onto the lower surface of the body and into the bubble-forming apertures. Air currents passing through the bubble-forming apertures cause the bubble solution to be released from the toy in a stream of bubbles.

Abstract: An apparatus (60) and system (20) are disclosed for the patient-controlled delivery of an analgesic or other beneficial agent 142, while preventing administration of a toxic quantity of the beneficial agent. The invention permits delivery of fractional doses to a patient in quantities which are directly proportional to the time period since the last dose or fraction thereof was delivered to the patient. In the preferred embodiments the apparatus includes a housing (58) including a casing (88) and a back plate (86), the housing containing a control switch (84) for opening and closing downstream conduit (62) and for depressing a floating plate (100) that thereby compresses a dose reservoir (90) with the beneficial agent (142) therein. A spring (124) biases the control switch (84).
