摘要： The present disclosure describes a detection system and methods for detecting a presence of a person or animal within a confined space with a low false alarm rate. The detection system may include a chemical detector to determine whether respiratory gas concentrations within the confined space exceed a predetermined concentration threshold. The detection system may further include an accelerometer-controlled, range-controlled radar unit to detect movement within the confined space during times in which acceleration of the confined space is less than a predetermined acceleration threshold. In this manner, a measured respiratory gas concentration that initially indicates a presence of a person or animal within the confined space may be confirmed by motion detection.

摘要： A method of processing image data of a scanned object includes performing, in integer format, a pixel offset correction on the image data using unsigned saturation arithmetic to produce an image in integer format having negative value pixels clipped to a value of zero. The resulting pixels are converted to floating point format and are multiplied by a positive floating point gain factor. The resulting pixels are further converted to integer format and clamped to a maximum value using saturation arithmetic. Non-functional pixel correction is performed in integer format, and the resulting pixel values are clamped to a maximum value using saturation arithmetic. The resulting pixel value is mapped in integer format to a palette index using a lookup table to establish an output pixel intensity having one of a plurality of intensity levels.
摘要翻译：处理扫描对象的图像数据的方法包括以整数格式，使用无符号饱和运算对图像数据进行像素偏移校正，以产生具有被削减为零值的负值像素的整数格式的图像。所得到的像素被转换为浮点格式，并乘以一个正的浮点增益因子。所得到的像素进一步转换为整数格式，并使用饱和度算术将其钳位到最大值。以整数格式执行非功能像素校正，并且使用饱和算术将所得到的像素值钳位到最大值。使用查找表将所得到的像素值以整数格式映射到调色板索引，以建立具有多个强度级别之一的输出像素强度。
