A sensor interface operates to communicate a sensed quantity along one or more processing pathways and in different data representations. The signal representations can be swapped along one or more locations of the signal processing branches. These branches are independent from one another and combined at an interface component for transmission along a single path or node for a control unit.

Sensor with interface for functional safety

A hardware monitor may receive information that identifies a requirement for a system. The requirement may be associated with operation of the system during a runtime operation of the system in an intended operating environment. The hardware monitor may program the one or more hardware components to analyze the system based on the requirement. The hardware monitor may receive a signal from the system during the runtime operation of the system in the intended operating environment. The hardware monitor may analyze the signal during the runtime operation of the system based on the requirement. The hardware monitor may determine, during the runtime operation of the system, that the requirement was violated during the runtime operation of the system based on analyzing the signal. The hardware monitor may output information indicating that the requirement was violated.

Requirement runtime monitor using temporal logic or a regular expression

Methods, systems and devices related to bidirectional edge-based pulse width modulation communication systems are disclosed. In some implementations, upon receipt of a predetermined trigger pulse at least two slave devices perform an action.

Edge-based communication with a plurality of slave devices

Methods and devices are provided wherein feedback is included in a checksum. An example method includes communicating between a first device and a second device. The method further includes including feedback information used by the first device as input to a checksum calculation, wherein the feedback information is not communicated concurrently with the checksum from the first device to the second device.

Efficient checksum communication between devices

Methods, devices and systems are disclosed where to generate a pulse a data line is actively driven to a first voltage followed by actively driving the data line to a second voltage.

Edge-based communication

A method comprises: detecting a first change of a physical property of a signal; starting a measurement of a duration of a first time interval that begins with the detection of the first change; detecting a second change of the physical property; stopping the measurement of the duration of the first time interval and starting a second measurement of a duration of a second time interval in response to the detection of the second change; detecting a third change of the physical property, and stopping the second measurement in response to detecting the third change; determining a relation of the durations of the first time interval and the second time interval from the first measurement and the second measurement; and determining the received data value based on the determined relation of the durations of the first time interval and the second time interval.

Self synchronizing data communication method and device

A method of receiving a data transmission includes detecting a first switching of a transmission signal to a first signal value, starting a duration measurement of a first time interval that begins with detecting the first switching of the transmission signal, detecting a second switching of the transmission signal to a second signal value, stopping the measurement of the first time interval duration and starting a second duration measurement of a second time interval, detecting a third switching of the transmission signal to the first signal value or to a third signal value, stopping the second measurement in response to detecting the third switching, determining a relation of the first and second time interval durations from the first and second measurements, and determining a data value of the transmission signal based on the determined relation.
