Disclosed is a system for detecting an operating state of a vehicle engine. The system comprises: an input coupled to a power line of a vehicle; means to filter out relatively high frequency transient noise components of a signal received from the power line; a first detector for receiving the filtered signal and detecting when transient noise associated with the power line rises above a first threshold and generating a first detection signal in response thereto; a second detector for receiving the filtered signal and detecting when the transient noise falls below a second threshold, which is lower than the first threshold, and generating a second detection signal in response thereto; and means for generating a first output signal in response to the first detection signal and a second output signal in response to the second detection signal.

The present invention relates to security systems and methods for vehicles and/or vehicle users that prevent the theft of vehicles, and/or that guarantee the security of the vehicle user. In order to achieve the above, the system of the present invention has an enabling system that controls the ignition of the vehicle, and/or a device for helmets intended for the monitoring of the security of the user, and makes it possible to determine, for example, whether the user is wearing the helmet and is using the same correctly, or whether the vehicle user has suffered an impact. Specifically, the system of the present invention has an interactive system (mobile device) associated with the user which, depending on the need, signals the enabling system to enable the vehicle ignition, provided that at least one condition is fulfilled, where a condition may be that the interactive system is close to the enabling system and/or emits an alert message to the external device of a third party if any novelty is detected in the helmet device.

A vehicle includes a cabin and a vehicle body including a cargo area rearward of the cabin. A tailgate assembly is mounted to the vehicle body that closes the cargo area. The tailgate assembly includes a rear-mounted video camera. An electronic control unit receives image data from the rear-mounted video camera. A connector communicatively couples the electronic control unit and the rear-mounted video camera. The connector has a closed configuration with the tailgate assembly mounted to the vehicle body and an open configuration with the tailgate assembly removed from the vehicle body. The electronic control unit includes logic that, wherein executed by a processor, causes the electronic control unit to receive signals from an alarm circuit when the connector is in the closed configuration and detect when the signals from the alarm circuit have stopped when the connector is in the open configuration.

An apparatus and method for monitoring the productivity of a portable machine are provided. The method includes receiving motion data for at least one component of the portable machine from a multi-axis accelerometer, receiving position data for the at least one component from a process parameter sensor communicatively coupled to the at least one component, and determining, based on the received motion data and the received position data that the at least one component is oriented in a predetermined position for productive operation. The method also includes determining an area of productive operation using at least one physical dimension of the at least one component and the received motion data when the at least one component is oriented in the predetermined position for productive operation and incrementing a total area counter based on the determination.

A system comprising a radar device and a mobile device. The radar device may be configured to operate when a vehicle is turned off, detect a presence of a person in the vehicle, determine an age range of the person detected and generate an alert signal in response to a presence signal and determining that the age range of the person detected corresponds to a child. The mobile device may be configured to communicate the presence signal to the radar device and determine a movement of the mobile device. The radar device may determine a distance of the mobile device from the vehicle in response to the presence signal. The radar device may suppress the alert signal when the distance of the mobile device is within a predetermined range of the vehicle and the mobile device is moving.

A system for vehicle interior detection, may include: a radar sensor having an emitting surface which emits a radar signal to a passenger compartment of a vehicle, and a plurality of conductive pins; a mounting bracket with which the radar sensor is mounted on a glass of the vehicle; a plurality of conductive layers which are provided on the glass; and a plurality of fixed contacts which are provided on the plurality of conductive layers, respectively, and which contact the plurality of conductive pins, respectively.

A system includes a vehicle cover, a mechanical tensioning device, a memory device, storing instructions, and one or more processors configured to execute instructions to perform the steps of a method to secure a vehicle. The mechanical tensioning device may include attachment means to attach the device to a wheel of the vehicle and means to attach a security cable of the vehicle cover integrated into a bottom edge of the vehicle cover to the mechanical tensioning device. The mechanical tensioning device may include a rotational reel connected to either a tensioning motor or a tensioning crank and optionally including either a mechanical bi-stable device or one or more sensors configured to monitor the tension of the security cable when engaged to the mechanical tensioning device. The processor may monitor for a change in tension and execute one or more security measures in response.

An external impact avoiding part makes a sensor failure detection part withhold from determining that a right or left door pressure sensor has failed when a right-left detection difference calculated at first time is a threshold value or larger, and makes a detection value comparison part calculate the right-left detection difference again after a calming time has elapsed. An effect of closing operation of a right door on the right door pressure sensor or an effect of closing operation of a left door on the left door pressure sensor reduces during the calming time. The avoiding part subsequently makes the detection part compare the right-left detection difference calculated again with the threshold value. As a result of the comparison, when the right-left detection difference is the threshold value or larger, the avoiding part makes the detection part determine that the right or left door pressure sensor has failed.

A disconnection detection device for an in-vehicle device having a load circuit, is provided with a second wire harness which is arranged along at least a part of the first wire harness, a current circuit which supplies a current for disconnection detection to the second wire harness, and a disconnection determination circuit which monitors an output voltage of the current circuit so as to determine presence or absence of disconnection of the second wire harness. Disconnection of the second wire harness is detected as the disconnection of the first wire harness based on disconnection determination of the disconnection determination circuit.

A vehicle security system may include a vehicle controller and a first wireless communications device coupled thereto, and at least one wireless sensor. The wireless sensor may include a housing having a threaded mounting surface, a motion sensor carried by the housing, a second wireless communications device carried by the housing, and a sensor controller carried by the housing. The sensor controller is configured to determine when motion of the housing exceeds a first threshold, and send a first security alert message to the vehicle controller based thereon via the second and first wireless communications devices, and determine when the first threshold is exceeded for a predetermined time and enter a power saving mode based thereon. The at least one sensor may also include a power source carried by the housing to power the motion sensor, second wireless communications device, and sensor controller.
