Abstract: A photo-acoustic gas sensor includes a light emitter unit having a light emitter configured to emit a beam of light pulses with a predetermined repetition frequency and a wavelength corresponding to an absorption band of a gas to be sensed, and a detector unit having a microphone. The light emitter unit is arranged so that the beam of light pulses traverses an area configured to accommodate the gas. The detector unit is arranged so that the microphone can receive a signal oscillating with the repetition frequency.

Abstract: A magnetic sensor may comprise a first linear output sensing element configured to sense a first component of an external magnetic field associated with a first axis. The first linear output sensing element may provide a first output voltage corresponding to the first component of the external magnetic field. The magnetic sensor may also comprise a second linear output sending component configured to sense a second component of the external magnetic field associated with a second axis. The second axis may be substantially orthogonal to the first axis. The second linear output sensing element may provide a second output voltage corresponding to the second component of the external magnetic field. The first output voltage and the second output voltage may be provided to determine an angle, associated with the external magnetic field, corresponding to a plane including the first axis and the second axis.

Abstract: A sensor comprises a matrix switch that includes a number of switching elements configured in a matrix configuration. The sensor comprises one or more sensor elements configured in a sensor matrix configuration. A controller operates to dynamically select one or more signal routes via the switching elements to communicate data from one or more sensor elements of the sensor matrix. The matrix switch can operate to dynamically route multiple signal routes between sensor elements of the sensor to another component based on a set of criteria.
