A process for producing an analytical aid for the detection of at least one analyte in a sample, such as a body fluid. The analytical aid includes at least one housing and at least one test element including at least one test chemistry. The process includes the following steps: providing the test element; and producing at least one housing part of the housing using at least one shaping process, during which the test element is connected to the housing part.

Systems and methods for using at least one sensor for monitoring a condition in a furnace are disclosed. The at least one sensor can be an optical fiber acoustic sensor. The at least one sensor can be coupled to at least one processor that can be configured to receive at least one measurement from the sensor, convert the at least one measurement into a digital format, and determine a condition associated with at least one burner based at least in part on the digital format. The digital format can be, for example, a sound waveform or a frequency spectrum.

A combustion controlling system according to the present invention provides a signal path for transmitting an ignition preparation signal SA output from a master device to a transmission line through cascade-connected slave devices. Then, each of the slave devices determines whether each of the slave devices outputs the ignition preparation signal to a subsequent device, or not, based on whether there is a flame of the corresponding burner, or not, at the time of igniting the burners, and the master device opens a safety shutoff valve on the condition that an ignition preparation signal SAo has been input from the transmission line.

A first reset switch is attached to a combustion controlling device. A second reset switch is installed at a remote place distant from the combustion controlling device. A first reset input from the first reset switch is received without any restriction to release the lockout. A reset input from the second reset switch is received with any restriction to release the lockout. Specifically, when the lockout releases are performed for a predetermined number of times or more upon receiving the reset input before a predetermined time elapses after the lockout has been released upon receiving the initial reset input, the release of the lockout upon receiving the reset input is prohibited until the predetermined time elapses.

In an embodiment, a system includes a gas turbine controller. The gas turbine controller is configured to receive a plurality of sensor signals from a fuel composition sensor, a pressure sensor, a temperature sensor, a flow sensor, or a combination thereof, included in a gas turbine engine system. The controller is further configured to execute a gas turbine model by applying the plurality of sensor signals as input to derive a plurality of estimated gas turbine engine parameters. The controller is also configured to execute a flame holding model by applying the plurality of sensor signals and the plurality of estimated gas turbine engine parameters as input to derive a steam flow to fuel flow ratio that minimizes or eliminates flame holding in a fuel nozzle of the gas turbine engine system.

An object of the present invention is to provide a gas leakage checking device and a method for the same, for checking fuel-gas leakage of safety shutoff valves simply and securely by measuring a pressure in a fuel supply pipe.
