摘要： An airbag deployment controller and a passenger protection device including the same are provided to prevent erroneous operation of an airbag due to noises and quickly deploy the airbag. The passenger protection device determines whether or not to drive an airbag unit, upon determining a detected value of a front acceleration sensor as being over a first collision threshold. Then, when determining to drive the airbag unit, the passenger protection device determines whether or not a detected value of a central acceleration sensor exceeds a second collision threshold. With the detected value being over the second threshold, it generates a driving signal and outputs it to the airbag unit in a final deployment control process. Thereby, the airbag unit operates an inflator to drive an airbag.

摘要： A vehicular occupant protection system includes an air bag sensor; a base signal generating unit that generates a base signal for abnormality diagnosis for the air bag sensor; a diagnosis-signal generating unit that generates a diagnosis signal for the air bag sensor base on the base signal; an abnormality diagnosing unit that executes the abnormality diagnosis by using output signal that the air bag sensor outputs based on the diagnosis signal; and a condition-signal generating unit that generates a condition for a start of generating of the diagnosis signal. Here, the diagnosis-signal generating unit generates the diagnosis signal based on the base signal when the condition signal satisfies a given condition.

摘要： A method for the transmission of sensor data from a sensor assembly to one or more receivers is presented, in which, in response to a control signal, additional data are transmitted at least temporarily for a short time instead of the sensor data, whereby only a certain limited value range of the value range that is available for the sensor data transmission is used for the transmission of the additional data, so that even with receivers which do not recognize that the transmitted data are additional data, erroneous functions or malfunctions are to be excluded. Thus, especially that value range of the sensor data signal that is to be attributed to a noise of the quantity to be measured or of the sensor assembly and is therefore not evaluated by the receiver in the normal signal operation, is used for the transmission of the additional data. In occupant protection systems, the safety-uncritical value range of a sensor data signal, which leads to no triggering of the occupant protection system, can correspondingly be used for the transmission of the additional data.

摘要： The disclosed invention uses two sensors to capture the heartbeat and environmental noises of an occupant of a vehicle or hospital bed. One of the sensors is placed on a seat or bed frame adjacent the occupant. A second sensor is placed remotely from the occupant, on a vehicle floor, or remote portion of the bed frame. A signal conditioning module is attached to the first and second sensors for detecting the heartbeat signal. Specialized software is used for processing the signal and decision making based upon the extracted heartbeat signal. The invention is capable of operating despite environmental noise and vibrations.

摘要： A method of detecting the improper mounting of a sensor on a motor vehicle includes monitoring the output signals of the sensor, determining the noise levels in the output signals, and comparing the noise levels from the output signals to a threshold noise value to determine if the sensor is properly mounted. Preferably, the method monitors the output signals of a first sensor and a second sensor, determines the noise levels in the output signals being emitted by each of the sensors, and compares the noise levels of the first sensor to the noise levels of the second sensor to determine if the sensors are properly mounted.

摘要： A vehicle collision detector is configured to reliably activate an airbag system at a collision and prevent the airbag system from erroneously operating. The collision detector includes two acceleration sensors disposed at different positions in a vehicle to detect acceleration for collision determination, first and second collision routines in which a determination is made on whether or not a variation in the detected acceleration is caused by a collision, and a final collision routine in which an airbag module is activated when all of results of the first and second collision routines indicate a collision.
