Abstract: A gas delivery system including a gas delivery device, a control module and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve assembly with a valve and circuit including a memory, a processor and a transceiver in communication with the memory. The memory may include gas data such as gas identification, gas expiration and gas concentration. The transceiver on the circuit of the valve assembly may send wireless optical line-of-sight signals to communicate the gas data to a control module. Exemplary gas delivery mechanisms include a ventilator and a breathing circuit. Methods of administering gas are also described.

Abstract: A system and method for conducting bi-directional communication sessions with sensing and control devices, such as utility meters, from a mobile device. A system for conducting bi-directional communication sessions with utility meters from a mobile device includes a mobile device capable of acquiring a communication session with a meter unit connected to a utility meter, a vehicle in which the mobile device is located, and a plurality of meter units connected to a plurality of utility meters. The meter units are capable of receiving and executing commands to obtain data and perform actions on the utility meters. The actions include a peak consumption value reset of the utility meter. Each command message includes a token that enables the endpoint radio transceiver devices to determine the commanded one or more operations have been performed.

Abstract: An optimized system for providing medical support to a patient is disclosed. The system comprises a plurality of modular components that may be assembled to create a connection between a support machine and the patient wherein at least one of the modular components comprises an information tag for the storage of data and at least one of the modular components comprises an information sensor for the reading and transmission of the data. Once read and transmitted by the sensor, the data may be used to optimize the operation of the support machine.

Abstract: A light diffusor (12) is disclosed which includes a translucent or transparent light diffusing portion (24) and a rigid mounting neck (25) coupled to the diffusing portion (24). The diffusing portion (24) has an inwardly extending flange (27) with a series of mounting hole (28) therein. The mounting neck (25) has a generally cylindrical, upright section (30) and an inwardly extending mounting flange (31). The neck inwardly extending mounting flange (31) has a series of mounting holes (33). The light diffusor also has first annular gasket (35) mounted between the mounting neck flange (31) and the diffusing portion flange (27), a second gasket (37) mounted below the diffusing portion flange, and three mounting brackets (40) mounted below the second gasket (37). The first gasket, second gasket and mounting brackets all have mounting holes (36), (37) and (41), respectively.

Abstract: A cassette for vaporization of anesthetic agent for delivery to a patient is arranged to be received by an anesthesia machine which has control mechanisms for controlling vaporization of the agent. In a preferred arrangement, the cassette includes a housing for receiving, containing and emitting anesthetic agent. A sensor, such as a pressure sensor or a temperature sensor is embedded in the housing for obtaining a value of the agent contained in the reservoir. The sensor is operatively connected to the reservoir to obtain an accurate value of the agent. A communication link is provided between the sensor and the control mechanisms of the anesthesia machine when the cassette is received by the anesthesia machine. The cassette thus provides a simplified arrangement that efficiently and accurately provides values of the anesthetic agent being vaporized in the reservoir.
