BACKGROUND

Gas detectors may be carried by workers in environments where there is potential for harmful gases. The gas detectors may be periodically tested and/or calibrated to ensure that the detector is working properly. This may be done using a gas testing system operable to supply a sample gas to the detector and analyze the response of the gas detector. In some workplaces, the testing may occur while a user is wearing other protective gear, such as gloves, suits, helmets, respiratory equipment, etc.

DETAILED DESCRIPTION

It should be understood at the outset that although illustrative implementations of one or more embodiments are illustrated below, the disclosed systems and methods may be implemented using any number of techniques, whether currently known or not yet in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, but may be modified within the scope of the appended claims along with their full scope of equivalents.

The following brief definition of terms shall apply throughout the application:

The term “comprising” means including but not limited to, and should be interpreted in the manner it is typically used in the patent context;

The phrases “in one embodiment,” “according to one embodiment,” and the like generally mean that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present invention, and may be included in more than one embodiment of the present invention (importantly, such phrases do not necessarily refer to the same embodiment);

If the specification describes something as “exemplary” or an “example,” it should be understood that refers to a non-exclusive example;

The terms “about” or “approximately” or the like, when used with a number, may mean that specific number, or alternatively, a range in proximity to the specific number, as understood by persons of skill in the art field; and

If the specification states a component or feature “may,” “can,” “could,” “should,” “would,” “preferably,” “possibly,” “typically,” “optionally,” “for example,” “often,” or “might” (or other such language) be included or have a characteristic, that particular component or feature is not required to be included or to have the characteristic. Such component or feature may be optionally included in some embodiments, or it may be excluded.

There is a strong desire for compliance based portable gas detectors to be as user friendly as possible. One of the ways this can be accomplished is by limiting the device to a single button, reducing the interaction between the user and device. One of the issues with this arises if multiple types of user/device interactions are required, and it becomes difficult to come up with different types of single button interactions (e.g. long button press, short button press, double press, etc.) to cover all operations or interactions.

In an example, gas detectors often require regular calibration (i.e. apply a known gas, read the sensor output, and adjust gas readings as needed) and bumping (i.e. apply a known gas to make sure all user alerts are still working as intended). Usually these actions are completed within a docking station or manually. When done manually, the problem described above may arise, where if there is only one button, it may be difficult to control the device to enter calibration or bump mode.

Applicants have proposed a process using near field communication (NFC) between the gas detectors and one or more NFC tag. The tube that supplies the gas sample to the detector that is used for calibration (cal) and bumping (bump) may be redesigned to incorporate a passive NFC tag near the end of the tubeoperable to attach to the detector device. The NFC tag will contain information such as gas type, concentration, and the action required (bump or cal). To interact with the NFC tag, an NFC reader may be incorporated into the gas detector. When the tube is in place it will be in close enough proximity of the reader that the device will automatically read the information off the tube's NFC tag and put the device in to the appropriate mode. The proposed solution requires no interaction between the user and the device other than attaching the tube, reducing the potential for error, and reducing the time required for the bump/cal process.

Referring now to FIG. 1A, a system 100 may comprise a detector device 102, such as a gas detector, one or more gas delivery tubes 104, and one or more NFC tags 105 attached to the gas delivery tubes 104.

The NFC reader 106 may be operable to receive input from the NFC tag(s) 105. In some embodiments, the gas detector device may comprise a memory 112 and a processor 114. Additionally, the gas detector device may comprise an application stored in the memory 112, that when executed by the processor 114 receives instructions from the NFC tag 105 via the NFC reader 106, and executes an action based on the instructions from the NFC tag 105.
