    • A shock sensor capable of detecting a shock in a number of directions includes a reed switch, which is fixed inside a body and has a reed contact part which is magnetically changed from a first to a second state by way of a magnet, which is fixed inside the body at a specified distance from the reed switch. A shield member, having a sufficiently large area, prevents the magnet force of the magnet from affecting the reed contact part when the shield member is in its regular position. A resilient member, in a normal state, keeps the shield member at its regular position between the reed contact part and a magnet, at which the reed contact part is kept in the first state. When a shock is applied to the shock sensor, the resilient member allows the shield member to move to a position where the reed contact part changes over to the second state.In a second embodiment, the magnet is movably held in the main casing at a specified distance from the reed switch. In a normal state, the position of the magnet is such that a magnetism does not affect the reed contact part. When a shock is applied to the shock sensor, the magnet moves to a second position where the reed contact part is changed over to the second state.
    • 能够检测多个方向的冲击的冲击传感器包括固定在主体内的舌簧开关,并且具有通过固定的磁体从第一状态向第二状态磁性地变化的簧片接触部, 在距离簧片开关指定距离的身体内。 具有足够大面积的屏蔽构件防止当屏蔽构件处于其正常位置时磁体的磁力影响簧片接触部分。 在正常状态下的弹性构件将屏蔽构件保持在簧片接触部分和磁体之间的规则位置,在该磁体处,簧片接触部分保持在第一状态。 当对冲击传感器施加冲击时,弹性构件允许屏蔽构件移动到簧片接触部分转换到第二状态的位置。 在第二实施例中,磁体以与舌簧开关规定的距离可移动地保持在主壳体中。 在正常状态下,磁体的位置使得磁性不影响簧片接触部分。 当对冲击传感器施加冲击时,磁体移动到第二位置,在该位置,簧片接触部分被切换到第二状态。

    • An engine knock detecting apparatus for sensing knocking occurring in an internal combustion engine. The engine knock detecting apparatus has a vibration sensor for sensing vibration having a vibration component caused by the knocking taking place in the engine and outputting an electric signal corresponding to the vibration. A feed back loop is formed by a first mean level detection circuit which determines and outputs the mean value of the electric signal derived from the vibration sensor, and a gain controller which controls the gain of an amplifier in accordance with the first mean level signal produced by the first mean level detection circuit, such that the amplified signal derived from the amplifier takes a level equal to or above a predetermined level. The amplified signal derived from the amplifier is compared by a comparator with a reference signal which is delivered through a second mean level detection circuit and a reference signal generator. A knocking signal representing the occurrence of engine knock is produced when the level of the reference signal is exceeded by the level of the amplified signal.

    • An engine knock sensor for sensing knocking occurring in an internal combustion engine. The vibration in the engine, involving the vibration component caused by the knocking, is sensed by a vibration sensor. A feed back control is achieved by a closed loop constituted by a variable-gain amplifier the gain of which is controllable and adapted for amplifting the electric signal from the vibration sensor corresponding to the vibration, a mean level detecting circuit for calculating the mean value of the level of the amplified signal and outputting a mean level signal, and a gain controller for effecting a control of the gain of the variable-gain amplifier in accordance with the mean level signal so as to maintain the level of the amplified signal above a predetermined level. A predetermined voltage is added to the mean level signal to produce a reference signal which is compared by a comparator with the amplified signal from the variable-gain amplifier. A knocking signal is produced when the level of the amplified signal exceeds the level of the reference signal.
