  • Patent number: 10728694
    Abstract: A compound sensor system includes a first sensor, a second sensor, a memory that stores a module, and a processor coupled to the first sensor, the second sensor, and the memory. The first sensor is configured to detect a parameter that indicates a likelihood of having a user enter or leave a target area, and, in response, send a first command signal to the processor. The processor is configured to receive the first command signal from the first sensor and send a second command signal to the second sensor based on receiving the first command signal. The second sensor is configured to operate at a sleep mode and switch to an active mode upon receiving the second command signal, and during the active mode the second sensor is configured to determine if the user enters or leaves the target area.

  • Patent number: 10706619
    Abstract: Systems, methods, and other embodiments described herein relate to a manner of extending the use of originally-equipped automotive vehicle sensors to environmental mapping. In one embodiment, a method includes acquiring sensor data from a vehicle-equipped detachable sensor of an environment around a non-automotive entity when the vehicle-equipped detachable sensor is mounted to the non-automotive entity. The vehicle-equipped detachable sensor is capable of sensing a portion of an environment around an automotive vehicle and configured to communicate with a computing device. The vehicle-equipped detachable sensor is also structured to be detached from the automotive vehicle and mounted to the non-automotive entity. Further, the method includes receiving a mapping request from the computing device. The method also includes, in response to the mapping request, building a map, from the acquired sensor data, of an area traveled by the non-automotive entity.

  • Patent number: 10670624
    Abstract: An electronic device configured for real-time calibration of an on-board accelerometer. A plurality of acceleration measurements are collected from the accelerometer to form a data set. An accelerometer error correction model is maintained that includes bias error calibration parameters, sensitivity calibration parameters, and cross-axis calibration parameters that each specify respective weights for each of bias error, sensitivity error, and cross-axis error. Calibration values are determined for one or more of the bias error calibration parameters, the sensitivity calibration parameters, and the cross-axis error calibration parameters for the data set of acceleration measurements using the accelerometer error correction model. A true acceleration vector may be determined that corresponds to a subsequently received acceleration measurement using the determined calibration values.
