According to an exemplary embodiment of the present invention, the bus architecture may comprise of a continuous serial bus that may be incorporated into a process control sample system to provide an intrinsically safe and efficient system. An alternative exemplary embodiment, in an intrinsically safe control sampling system, a data transport device may be used to couple sampling controls and analyzers. An exemplary embodiment of the present invention may contain an access controller providing a protocol bridge for an intrinsically safe control sampling system to couple sampling controls and analyzers.

Abstract: A system and method for providing an intrinsically safe (IS) galvanically isolated barrier device. An IS barrier device provides IS galvanic isolation between a non-IS system and an IS system using a two-stage approach. In the first stage, a non-galvanically isolated IS barrier limits energy of electrical transmissions received from the non-IS system to convert such electrical transmissions into IS transmissions. In the second stage, the IS transmissions are transmitted through a galvanic isolator to the IS system to galvanically isolate the IS system from the non-IS system. A digital monolithic isolator cannot be IS certified to be the single bridge between IS and non-IS systems, however, it can be used in a certifiable fashion to isolate between IS systems.

Abstract: A system and method for providing a serial communication bus is disclosed. A serial communication bus connects multiple footprint devices, such as electronic sensors in a process control sample system. The footprint devices can utilize various footprint device specific communication protocols. Multiple tophat devices act as general I/O ports for connecting with the footprint devices. Each tophat device identifies the footprint device specific communication protocol of a connected footprint device, converts outputs signals transmitted from the connected footprint device from the footprint device specific communication protocol of the footprint device to a standard bus communication protocol, and converts input signals directed to the connected footprint device from the standard bus communication protocol to the footprint device specific communication protocol of the footprint device.

Abstract: A system, method, and device for amplifying the signal of a photodiode are provided. The exemplary system may have a photodiode with an amplifier. The amplifier may have an amplifier inverting input, an amplifier non-inverting input, and an amplifier output. A photodiode of the system may have a photodiode anode electrically connected with the amplifier inverting input and a photodiode cathode electrically connected with the amplifier non-inverting input. A gain resistor of the system may couple the amplifier inverting input with the amplifier output. The system may also have a fixed voltage reference electrically connected with the photodiode cathode and the amplifier non-inverting output.

Abstract: An ink supply container for an ink-jet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. A fill port is provided for directing ink into the reservoir to fill the reservoir. The apparatus and method for filling the ink container includes a nozzle that seals around the fill port and that has valved fluid lines connected thereto for evacuating the container prior to filling and for directing ink into the evacuated reservoir. The nozzle surrounds a plug that is moved to seal the port while the nozzle is still sealed around the port immediately after the container is filled.
