摘要	A system for transmitting wireless power from multiple sources to multiple receivers, in which the safety of the system is maintained in spite of the possibility that two beams may intersect in the transmission space, thereby generating power or power density levels which exceed those at which the safety mechanisms of the system were designed to operate. The paths of the beams are known from the transmission positions and directions, and from the positions and orientations of the receivers, as measured by positioning devices on them. When an intersection, or near intersection of beams is determined, the system is triggered to reduce the safety risk by attenuating or turning off, or by diverting, one or more of the beams. In addition, since a reflected beam's path may not be readily discernable, the system can ascertain if one of the beams has undergone a reflection, by looking for displayed mirror images.
其他摘要	一种用于从多个源向多个接收器发送无线功率的系统，其中尽管两个波束可能在传输空间中交叉，但仍保持系统的安全性，从而产生超过其中的功率或功率密度水平。该系统的安全机制旨在运作。从传输位置和方向以及接收器的位置和方向可知光束的路径，如通过定位装置在其上测量的。当确定交叉点或近梁的交叉点时，触发系统以通过衰减或关闭或通过转移一个或多个梁来降低安全风险。另外，由于反射光束的路径可能不容易辨别，因此系统可以通过查找显示的镜像来确定其中一个光束是否经历了反射。
主权项	A method of ensuring safety in a multiple beam wireless power transmission system comprising beam sources and multiple targets, said method comprising the steps of: (a) determining if any points on trajectories of at least two beams come closer to each other than a predefined safe distance, and if so, either performing at least one of (i) attenuating at least one beam, (ii) turning off at least one beam, and (iii) diverting at least one beam; or sending data associated with said determining to a controller, said controller being adapted to perform at least one of (i) attenuating at least one beam, (ii) turning off at least one beam, and (iii) diverting at least one beam, based on analysis of said data, and (b) detecting if there is a reflective surface in the path of any beam by receiving at said transmission system, image data of a pattern on a target, and determining if an image generated from said image data has a mirror-imaged form compared to that of said pattern on said target, and if so, either performing at least one of (i) attenuating, (ii) turning off, and (iii) diverting at least the beam directed at that target whose image data of a pattern thereon has a mirror-imaged form; or sending data associated with said determining to a controller, said controller being adapted to perform at least one of (i) attenuating, (ii) turning off, and (iii) diverting at least the beam directed at that target whose image data of a pattern thereon has a mirror-imaged form, based on analysis of said data.
