    • Embodiments relate to TPMS utilizing a single-axis acceleration sensor for measuring the direction of rotation of the tires in a tire localization methodology. In an embodiment, the known axis position of the acceleration sensor in the tires allows for the assessment by an integrated circuit in order to determine the left or right positioning of a tire, as well as the magnitude of acceleration or deceleration. Because of the dual components of the measured acceleration signal of first, the directional acceleration of the vehicle and second, the oscillating modulation due to gravity, the generated waveform is known to have differences between the left and right tire signals of an accelerating and decelerating vehicle. The impact of the oscillating modulation on the directional acceleration of the vehicle can be utilized to identify tire rotation direction, and thus the wheels localized therefrom, as well as the magnitude of acceleration and deceleration.
    • 实施例涉及利用单轴加速度传感器在轮胎定位方法中测量轮胎的旋转方向的TPMS。 在一个实施例中,轮胎中加速度传感器的已知轴位置允许通过集成电路进行评估,以便确定轮胎的左或右定位以及加速度或减速度的大小。 由于首先测量的加速度信号的双重分量,车辆的方向加速度和第二,由重力引起的振荡调制,已知生成的波形在加速和减速车辆的左右轮胎信号之间具有差异 。 振荡调制对车辆方向加速度的影响可以用于识别轮胎旋转方向,从而确定轮子的转向方向,并且因此轮子的位置以及加速度和减速度的大小。

    • A photodetector includes a substrate and an insulating arrangement formed in the substrate. The insulating arrangement electrically insulates a confined region of the substrate. The confined region is configured to generate free charge carriers in response to an irradiation. The photodetector further includes a read-out electrode arrangement configured to provide a photocurrent formed by at least a portion of the free charge carriers that are generated in response to the irradiation. The photodetector also includes a biasing electrode arrangement that is electrically insulated against the confined region by means of the insulating arrangement. The biasing electrode arrangement is configured to cause an influence on a spatial charge carrier distribution within the confined region so that fewer of the free charge carriers recombine at boundaries of the confined region compared to an unbiased state.
    • 光电检测器包括基板和形成在基板中的绝缘布置。 绝缘布置使基板的受限区域电绝缘。 受限区域被配置为响应于照射产生无电荷载流子。 光电检测器还包括被配置为提供由响应于照射而产生的至少一部分自由电荷载体形成的光电流的读出电极装置。 光电检测器还包括通过绝缘装置与受限区域电绝缘的偏置电极装置。 偏置电极装置被配置为对受限区域内的空间电荷载流子分布产生影响,使得与无偏压状态相比,较少的自由电荷载流子在限制区域的边界处复合。
