    摘要： Methods for determining the presence of an unmeasured chemical in an environment can include receiving a plurality of sensor readings from a plurality of chemical sensors, wherein each chemical sensor of the plurality of chemical sensors is configured to detect a different chemical, determining a cross-sensitivity pattern from one or more unmeasured chemicals in the plurality of sensor readings, comparing the cross-sensitivity pattern with one or more known chemical patterns, determining that the cross-sensitivity pattern matches at least one of the one or more known chemical patterns that correspond to one or more chemicals, and identifying one or more unmeasured chemicals based on determining that the cross-sensitivity pattern matches the at least one of the one or more known chemical patterns.

    摘要： In an embodiment, an apparatus (e.g., a gas detection device) includes a housing, a printed circuit board (PCB), one or more radio modems with a switching network. The housing includes a conductive cover and the cover plays as an antenna. The PCB may be fixed in the housing and includes a ground plane and a plurality of conductive feeds. Each feed are vertically mounted directly or indirectly on the PCB. When the cover is attached to the housing, each of the feeds electrically contact a respective connection point on the antenna. The switching network is to configure which feed should be connected to the radio modem. A extra grounding resistor is mounted or not to change antenna type to enhance the performance of antenna.
