Abstract: An image sensor generates first digital samples and second digital samples during respective first and second sampling intervals, the first digital samples including at least one digital sample of each pixel of a first plurality of pixels, and the second digital samples including at least one digital sample of each pixel of a second plurality of pixels. A sum of the first digital samples is accumulated within a first counter as the first sampling interval transpires, and a sum of the second digital samples is accumulated within the first counter as the second sampling interval transpires.

Abstract: A method of operation in an integrated circuit (IC) memory device is disclosed. The method includes refreshing a first group of storage rows in the IC memory device at a first refresh rate. A retention time for each of the rows is tested. The testing for a given row under test includes refreshing at a second refresh rate that is slower than the first refresh rate. The testing is interruptible based on an access request for data stored in the given row under test.

Abstract: A user interface includes both a touchscreen for tactile input and one or more lensless optical sensors for sensing additional, remote gestures. Users can interact with the user interface in a volume of space near the display, and are thus not constrained to the relatively small area of the touchscreen. Remote hand or face gestures can be used to turn on or otherwise alter the tactile user interface. Shared user interfaces can operate without touch, and thus avoid cross-contamination of e.g. viruses and bacteria.

Abstract: A dynamic random access memory (DRAM) array is configured for selective repair and error correction of a subset of the array. Error-correcting code (ECC) is provided to a selected subset of the array to protect a row or partial row of memory cells where one or more weak memory cells are detected. By adding a sense amplifier stripe to the edge of the memory array, the adjacent edge segment of the array is employed to store ECC information associated with the protected subsets of the array. Bit replacement is also applied to defective memory cells. By implementing ECC selectively rather than to the entire array, integrity of the memory array is maintained at minimal cost to the array in terms of area and energy consumption.

Abstract translation: 动态随机存取存储器（DRAM）阵列被配置用于阵列的子集的选择性修复和纠错。 将纠错码（ECC）提供给阵列的选定子集，以保护检测到一个或多个弱存储器单元的行或部分行的存储单元。 通过向存储器阵列的边缘添加感测放大器条纹，阵列的相邻边缘段用于存储与阵列的受保护子集相关联的ECC信息。 位更换也适用于有缺陷的存储单元。 通过有选择地执行ECC而不是整个阵列，在面积和能量消耗方面，以阵列的最低成本保持存储器阵列的完整性。

Abstract: Row activation operations within a memory component are carried out with respect to subrows instead of complete storage rows to reduce power consumption. Further, instead of activating subrows in response to row commands, subrow activation operations are deferred until receipt of column commands that specify the column operation to be performed and the subrow to be activated.

Abstract translation: 存储器组件内的行激活操作相对于子行执行，而不是完整的存储行，以减少功耗。 此外，代替激活响应于行命令的子代码，延迟激活操作被延迟，直到接收到指定要执行的列操作的列命令和被激活的子代。

Abstract: In an integrated-circuit image sensor, binary sample values are read out from an array of pixels after successive sampling intervals that collectively span an image exposure interval and include at least two sampling intervals of unequal duration. Each pixel of the array is conditionally reset after each of the successive sampling intervals according to whether the pixel yields a binary sample in a first state or a second state.

Abstract: A pixel within a pixel array of an integrated-circuit image sensor outputs an analog signal representative of accumulated photocharge. First and second analog-to-digital conversions of the analog signal are initiated while the pixel is outputting the analog signal, the first analog-to-digital conversion corresponding to a low-light range of photocharge accumulation within the pixel and the second analog-to-digital conversion corresponding to a brighter-light range of photocharge accumulation within the pixel.

Abstract: An image sensor architecture with multi-bit sampling is implemented within an image sensor system. A pixel signal produced in response to light incident upon a photosensitive element is converted to a multiple-bit digital value representative of the pixel signal. If the pixel signal exceeds a sampling threshold, the photosensitive element is reset. During an image capture period, digital values associated with pixel signals that exceed a sampling threshold are accumulated into image data.
