An incoming call alert adapter makes use of connections to audio player devices and audio output devices for alerting the users of these devices to incoming calls on a nearby mobile telecommunications device. The alert adapter interrupts an audio signal that passes from the audio player device to the audio output device through a series of connections within the alert adapter when an incoming call-back signal is detected on a nearby mobile telecommunications device. The interrupted audio signal alerts the user, who may riot have heard the audible alert of the mobile telecommunications device of the incoming call over the audio from the audio playback device.

A torque transmission device includes a pulley, a cylindrical member, a torque limiter and a weight member. The pulley is rotated by torque transmitted from a drive source. The cylindrical member is connected to a rotatable shaft of a compressor and is rotated integrally with the rotatable shaft. The torque limiter is arranged between the pulley and the cylindrical member and transmits the torque from the pulley to the cylindrical member. The torque limiter disables the transmission of the torque when the torque becomes equal to or greater than a predetermined value. The weight member is secured to the cylindrical member at a point closer to the rotatable shaft than the torque limiter.

Depending on the position of the pistons (6, 7), faces (6A, 7A) of the respective pistons are either spaced apart or adjacent. The additional switch piston (7) is adjustable depending on a pilot pressure (p_K) of a switching element which engages a gear for forward drive.

A vehicle antitheft device prevents an erroneous activation of a theft preventing function due to an activation of a system, which is capable of starting an engine in a state where a key is not inserted in an ignition key cylinder. A power source control device causes a starter motor to start the engine when the key is inserted into the ignition key cylinder or an authentication collation through a radio communication is completed. The vehicle antitheft device activates an alarm when an IG signal from the power source control device becomes an ON signal in an uninserted state of the key into the ignition key cylinder. A push start switch, which is push-operated at a time of an engine start, is connected to the power source control device and the vehicle antitheft device. The power source control apparatus turns an ACC signal and the IG signal supplied to the vehicle antitheft device to an ON state in that order when the collation with the portable equipment through a radio communication is completed after an operation of the push start switch. The vehicle antitheft device changes a security function to an unvigilant state when the ACC signal is changed to an ON state.

The invention belongs to the field of automobile assembling and particularly relates to a wheel sensor calibration system and a control method thereof. A directional transmission antenna is adopted for directionally sending a low-frequency trigger signal to a target wheel sensor, and wheel sensors nearby are prevented from being mistakenly activated. In addition, feedback type power gradual change triggering is adopted, and the power of the trigger signal is gradually increased from the preset lowest power till the target wheel sensor sends a response signal. It is guaranteed that the trigger signal activates the target wheel sensor through the minimum receivable power. The wheel sensors nearby are further prevented from being mistakenly activated.

An electronic device with human body induction and a human body induction control method are provided, The device includes a signal processing unit, an image acquisition unit, a distance measuring unit, an image recognition unit and an image tracking unit. When the pattern acquisition unit detects a human body real-time image, the distance measuring unit is made to start working, and the signal processing unit compares the measured distance with the preset distance. When the measured distance is smaller than the preset distance, the image recognition unit and the image tracking unit operate, and the electronic device starts to recognize the human motion signal or receive the speech signal, and starts to work according to the recognized or received signal. The invention is reasonable in design and reliable in operation, and the electronic device is only partially activated when the human body approaches, and is fully activated when the human body reaches a preset distance, that is, thedouble-layer activation is required, thereby avoiding the situation that the infrared signal is unstable due to environmental factors and thus causes misactivatoin of the device, and prolonging the life of the device.

An escapement fuze self-destruct mechanism for a projectile includes a drive weight that maintains a biasing member in a compressed state by centrifugal force when a projectile's RPM speed is above a preselected threshold. When the RPM speed falls below the preselected threshold, the biasing member exerts sufficient counter-rotational force to overcome the centrifugal force exerted by the drive weight. The biasing member expands to an uncompressed state and displaces the drive weight into position for mechanically implementing self-destruction of the projectile if a rotor is fully armed or for rendering the projectile “safe” if the rotor is in any position other then fully armed.

The invention relates to a lane change assistance system in a vehicle (21), wherein the lane change assistance system has a sensor arrangement for detecting the current surrounding area of the vehiclein each case and is designed to generate a warning signal and/or steering intervention when an imminent lane change by the vehicle is identified, depending on a second vehicle (25) being detected bythe sensor arrangement in the vehicle's surrounding area. In this case the lane change assistance system is designed to suppress generation of the warning signal and/or the steering intervention basedon map data (15), particularly when the change of lane by the vehicle is to a newly opening lane (23) of a multiple lane road (22) which is branching off (e.g. of a corresponding motorway exit) and the second vehicle is located in another lane (24) of the road (22) which is branching off.
