摘要： A wetness sensor includes a substrate that carries a tuned RF circuit. The circuit includes a conductive pattern applied to the substrate, a capacitor, and a jumper all disposed on a same side of the substrate. The conductive pattern includes an inductive coil, and an inner and outer terminus. The jumper electrically couples the inner terminus to the outer terminus. The jumper also includes a frangible link which, when contacted by a target fluid, produces a drastic change in the operation of the RF circuit. The drastic change can be interpreted by a remote reader as a "wet" condition. Contact of the frangible link by the target fluid may change the impedance or resistance of the RF circuit by at least a factor of 5, 10, 100, or more, and/or may cause the frangible link to disintegrate to produce an open circuit, and/or may substantially render the RF circuit inoperative.
摘要翻译：湿度传感器包括承载调谐RF电路的基板。电路包括施加到衬底的导电图案，电容器和全部设置在衬底的同一侧上的跳线。导电图案包括感应线圈，以及内外端。跳线将内部终端电连接到外部终端。跳线还包括一个易碎的连接，当与目标流体接触时，它产生了RF电路的操作的剧烈变化。远程读取器可以将剧烈的变化解释为“湿”状态。通过目标流体的易断裂连接的接触可以将RF电路的阻抗或电阻改变至少5,10,100或更多的因子，和/或可以使易碎连杆分解以产生开路，和/或可以基本上使得RF电路不起作用。

摘要： In some examples, a computing device receives an image of an optically active article that includes a set of one or more symbols of a symbol set, wherein at least one symbol of the set of one or more symbols comprises a set of encoding regions that are embedded with the symbol. In response to receiving the image, the computing device may determine that a particular image region of the image represents the at least one symbol. For encoding regions within the at least one symbol, the computing device may determine, based at least in part on the determination that the particular image region of the image represents the at least one symbol, whether the one or more encoding regions are active or inactive. The computing device may perform, based at least in part on whether the one or more encoding regions are active or inactive, one or more operations.

摘要： Embodiment herein provides an Infrastructure article (101) and method thereof for synchronizing blinks of infrastructure articles in a mesh network. The method includes detecting an expiry of a sync timer counted by a real time clock (RTC) and determining whether a charge level of a battery (105) of the infrastructure article (101) meets a battery charge threshold. When the charge level of the battery (105) of the infrastructure article (101) meets the battery charge threshold, the method includes establishing a connection with other infrastructure article and/or an infrastructure article server (200) in the mesh network, and sending a time to synchronize blink of the at least one light source (106) to all other infrastructure articles in the mesh network. When the charge level of the battery (105) of the infrastructure article (101) does not meet the battery charge threshold, the method includes resetting the sync timer, and initiating a count of the sync timer.

摘要： Example systems disclosed herein include a pathway-article assisted vehicle (PAAV) that utilizes an autonomous navigation system for navigating temporary zones on vehicle pathways. The PAAV includes at least one image capture device and a computing device. The image capture device generates an image that includes an indication of a temporary zone on a vehicle pathway, such as a pathway article proximate to the vehicle pathway that indicates the temporary zone. The computing device processes the image to obtain the indication of the temporary zone from the image, such as a code on the pathway article, and modifies, based on the indication of the temporary zone, a mode of autonomous operation of the PAAV while operating within the temporary zone on the vehicle pathway.
