A method for providing sensor data, including providing a maximum measuring range for the sensor, providing a first measuring range which is within the maximum measuring range, providing the sensor data in a data structure having a size that corresponds to the first measuring range, providing a second measuring range which is different from the first measuring range and is within the maximum measuring range, adapting the provided sensor data of the first measuring range for the second measuring range so that the adapted sensor data are provided in an expanded data structure having a size that corresponds to the maximum measuring range, and the provided sensor data being arranged as a function of the difference of the size between the maximum and the second measuring range and the size of the second measuring range within the expanded data structure, and the sensor-data-free sections being filled with values.

Method for providing sensor data of a sensor, and sensor system

An interface for an I3C slave. The interface allows I3C slaves to also be connected to a conventional I2C bus that includes an I2C master. For this purpose, an additional adaptation device is provided that adapts the signals of the I2C bus for an I3C slave.

A sensor device includes an oscillator element that is suppliable with a trigger signal, an activation and deactivation of at least one sensor element of the sensor device being initiatable with the aid of the trigger signal and an activation element, and at least one piece of sensor data of the at least one sensor element being storable in a register after the at least one sensor element is activated; and an interface connected to the register and via which the piece of sensor data is transmittable to the control device.

Sensor device

A sensor system for outputting sensor data, including at least one sensor element, a provision device for providing sensor data of the at least one sensor element, a control device for controlling the at least one sensor element, and an output device for outputting sensor data of the at least one sensor element; a data processing device being set up, with the aid of which the control device is configurable to provide a time interval between the time of providing the sensor data and the time of outputting sensor data via the output device, and the sensor data provided may be fetched out of the provision device and/or modified and/or written back to the provision device within the time interval provided.

Sensor system for outputting sensor data

A sensor system including a sensor data buffer, the sensor data buffer being configured in such a way that sensor data are organized in frames. The sensor data buffer is configured in such a way that a frame has a header and a sensor data area.

Sensor system with a sensor data buffer

A method for synchronizing sensors. A ratio of a first data rate of the first sensor to the second data rate of the second sensor is 2, where n is an element from the set of natural numbers. A central timer is started. A first countdown timer is generated based on the central timer and the first data rate, and a second countdown timer is generated based on the central timer and the second data rate. The first countdown timer and the second countdown timer are started periodically. The measurement by the first sensor begins at the latest when a first latency equals the value of the first countdown timer, and the measurement by the second sensor begins at the latest when the second latency equals the value of the second countdown timer.

Method and device for synchronizing sensors

A method for controlling an IC slave device with the aid of a control device, including: evaluating states on a data line and on a clock line of the IC bus; and assigning the states on the data line and on the clock line to states in a state diagram, control signals for the IC slave device being generated with the aid of the control device from the states in the state diagram.

In a method for protecting sensor data from manipulation, in the context of an authentication of the sensor, a number used once is sent from a control unit to the sensor, the sensor generating with the use of the number used once a cryptographic authentication message and sending at least a first part of the cryptographic authentication message to the control unit. In addition, the sensor data are provided with a cryptographic integrity protection, time-variant parameters being added to the sensor data and the sensor data being sent with the cryptographic integrity protection and the added time-variant parameters from the sensor to the control unit. For calculation of the initial parameters, at least a second part of the cryptographic authentication message is utilized.

A memory module has at least one secure and at least one insecure memory area, separate write/read electronic units for each of the memory areas and at least one shared analog circuit part such as a voltage supply circuit for supplying the write/read electronic units and/or the memory areas.

Memory module for simultaneously providing at least one secure and at least one insecure memory area

A method for operating a security device includes a microcontroller, a protected memory area, in which at least one item of protection-worthy information is stored, and a unit, the microcontroller being connected to the protected memory area via the unit, the at least one item of protection-worthy information being accessed by the microcontroller via the unit when the method is carried out.
