  • Publication number: 20150245116
    Abstract: An audio unit, connected or connectable to a safety-critical apparatus, or integrated or integrable in the apparatus, is proposed. The audio unit may comprise a driver unit, a detection unit, and an alert unit. The driver unit may generate an analog audio signal in response to a request from the apparatus, to drive an acoustic output unit and thereby generate an acoustic signal for a user of the apparatus. The detection unit may detect the audio signal. The alert unit may generate an alert signal in response to the request if the detection unit has not detected the audio signal. It can thus be checked whether the acoustic signal is generated. A method for generating a safety critical acoustic signal is also described.

  • Patent number: 9116049
    Abstract: A thermal sensor system which includes a thermal sensor and a voltage control network which applies a reference voltage level and a delta voltage level to the same or different thermal sensors. The thermal sensor develops a reference current signal in response to the reference voltage level and a delta current signal in response to the delta voltage level. A current gain network adjusts gain of the delta current signal. A current compare sensor, which is responsive to the reference current signal and the delta current signal, provides a comparison metric. A controller controls the current gain network to adjust gain of the delta current signal while monitoring the comparison metric to determine a gain differential value indicative of a current ratio between the current signals. The controller determines a temperature value based on the gain differential value. A LUT may be used to retrieve the temperature.
