摘要： Table saws are disclosed. The table saws can include a blade, an arbor, an arbor block, an elevation carriage, and a latch that connects the arbor block and the elevation carriage. The arbor block can have a first position in which the latch connects the arbor block and the elevation carriage, and a second position in which the latch does not connect the arbor block and the elevation carriage. The arbor block can pivot from the first position to the second position upon the occurrence of a retraction force. The table saw can include an actuator to cause the occurrence of the retraction force, and detection electronics to detect contact between the blade and a person. Woodworking machines with detection and reaction systems are also disclosed. A reaction system can include an explosive that causes retraction of a cutting tool.

摘要： A turf cutter device, an infill extractor/collector device, and a turf wind-up device are used to facilitate the cost-effective removal of an infilled synthetic turf and the subsequent installation of a new turf at the same site, with minimal subsurface disruption. An infill extractor/collector device mounted on a motorized vehicle moves a relatively narrow strip of filled artificial turf from the surface, in front of the vehicle, and directs the strip to an infill removal station. The infill removal station inverts the strip and redirects the strip back toward the front of the vehicle, after agitating the strip to extract the infill. After redirecting the strip toward the front of the vehicle, the vehicle drives over the unfilled strip. Meanwhile, the extractor/collector device moves the extracted infill rearwardly to a bag located in a trailer. The turf cutter device is used prior to infill extraction, while the turf wind up device may be used before or after infill extraction, depending on whether infill extraction takes place at the field or at a remote site, respectively.

摘要翻译： 使用草坪切割装置，填充提取器/收集器装置和草皮卷绕装置来促进填充的合成草皮的成本有效的去除以及随后在相同的部位安装新的草皮，同时具有最小的地下破坏 。 安装在机动车辆上的填充提取器/收集器装置从车辆前方的表面移动相对狭窄的填充人造草皮条，并将条带引导到填充物移除站。 在搅拌条带以提取填充物之后，填充物移除站反转条并将带重新导向车辆的前部。 在将钢带重新导向车辆前部后，车辆在未填充钢带上行驶。 同时，提取器/收集器装置将提取的填充物向后移动到位于拖车中的袋子。 草皮切割装置在填充提取之前使用，而草坪卷起装置可以在填充提取之前或之后使用，这取决于是否在现场或在远程位置进行填充提取。

摘要： Methods to detect when a human body contacts a predetermined portion of a machine are disclosed. The methods distinguish contact with a person from contact with other materials. The methods are particularly applicable in woodworking equipment such as power saws to distinguish contact between a person and the blade of the saw from contact between the blade and wet or green wood. Woodworking machines and memory devices for use in woodworking machines having safety systems designed to detect a dangerous condition between a human and a dangerous portion of the woodworking machine and to trigger some action to mitigate the dangerous condition are also disclosed.
