    Abstract: The modulation scheme disclosed in this invention report allows for utilizing multiple 3D time-of-flight cameras at the same time by exploiting the inherent pseudo noise properties of the optical modulation signals. Compared to recent systems based on pure pseudo noise modulation signals, the stochastic measurement error in a single-camera environment is significantly reduced. The basic concept relies on the generation of a three level optical modulation signal that includes two pseudo noise sequences.

    Abstract: The invention describes an electronic travel aid (ETA) for blind and visually impaired persons implemented in a detachable handle of a white cane. The device enhances the functionality of the white cane giving the user more detailed information about the environment within a defined corridor of interest in front of the user with an extended range of a few meters up to 10 m. It provides a reliable warning if there is a risk of collision with obstacles including those at trunk or head height, which are not recognized by a conventional white cane. Additional sensors are integrated to delimit the defined corridor during the cane sweeping thereby reducing the amount of information that is transmitted to the user via the tactile interface. Alternatively, the device can be used independently from the cane as an object recognition and orientation aid.

    Abstract: A pixel (1) is formed in a semiconductor substrate (S) with a plane surface for use in a photodetector. It comprises an active region for converting incident light (In) into charge carriers, photogates (PGL, PGM, PGR) for generating a lateral electric potential (F(x)) across the active region, and an integration gate (IG) for storing charge carriers generated in the active region and a dump site (Ddiff). The pixel (1) further comprises separation-enhancing means (SL) for additionally enhancing charge separation in the active region and charge transport from the active region to the integration gate (IG). The separation-enhancing means (SL) are for instance a shield layer designed such that for a given lateral electric potential (F(x)), the incident light (In) does not impinge on the section from which the charge carriers would not be transported to the integration gate (IG).

    Abstract: A demodulation image sensor, such as used in time of flight (TOF) cameras, extracts all storage- and post-processing-related steps from the pixels to another array of storage and processing elements (proxels) on the chip. The pixel array has the task of photo-detection, first processing and intermediate storage, while the array of storage and processing elements provides further processing and enhanced storage capabilities for each pixel individually. The architecture can be used to address problems due to the down-scaling of the pixel size. Typically, either the photo-sensitivity or the signal storage capacitance suffers significantly. Both a lower sensitivity and smaller storage capacitances have negative influence on the image quality. The disclosed architecture allows for keeping the storage capacitance unaffected by the pixel down-scaling.

    Abstract translation: 诸如在飞行时间（TOF）照相机中使用的解调图像传感器从芯片上的像素到存储和处理元件（代码）的另一个阵列提取所有存储和后处理相关的步骤。 像素阵列具有光检测，第一处理和中间存储的任务，而存储和处理元件阵列分别为每个像素提供进一步的处理和增强的存储能力。 该架构可用于解决由于像素尺寸的缩小而导致的问题。 通常，光敏性或信号存储电容显着地受损。 较低的灵敏度和较小的存储电容对图像质量都有负面影响。 所公开的架构允许保持存储电容不受像素缩小的影响。

    Abstract: A demodulation structure for an n-tap pixel, mainly for 3D time-of-flight (TOF) applications uses a 2-stage switch structure for demodulating a modulated electromagnetic wave. An almost arbitrary number of storage sites per pixel can be implemented enabling an almost arbitrary number of samplings captured during one exposure. It also provides the option to demodulate and integrate different phasing samples according to the different modulation frequencies within the same exposure.
