A fail-safe wireless power transmission system having a transmitter, a receiver, a receiver functionality monitor unit, a transmitter functionality monitor unit and at least two sensors. The transmitter has at least one low emission state, and at least one high emission state, the high emission states having higher emissions and more complex safety systems. The transmitter may be precluded from switching from a low emission state to any high emission states upon detection of a receiver control unit malfunction, a transmitter control unit malfunction, a likelihood of human-accessible emission from the system greater than a predetermined level, or an inconsistency between results arising from at least two of the sensors. Two different methods of such preclusion may be used simultaneously or consecutively to improve reliability. A transmitter control unit analyzes data from the sensors, and performs calculations to determine if and what type of preclusion is needed.

Fail-safe optical wireless power supply

Aspects of embodiments pertain to a method for determining an Input/Output (I/O) device configuration for a music teaching system. The method may comprise receiving a plurality of I/O device configurations of a music teaching system; receiving, for a given I/O device of the music teaching system, an initial I/O device configuration; and determining an updated I/O device configuration for the given I/O Device, based on the initial I/O device configuration of the given I/O Device and at least one of the plurality of received I/O device configurations. The determining is performed such that the updated I/O device configuration has improved device performance compared to the initial I/O device configuration.

Crowd-based device configuration selection of a music teaching system

A system for ensuring the integrity of the enclosure of a wireless power transmitter. The enclosure of the transmitter comprises a window in order to allow a high-power beam to exit the transmitter. The window is equipped with an area which reflects at least a portion of the beam, and directs the reflected beam onto a detector. Thus the system can ascertain whether the window is undamaged, since if the detector is receiving a satisfactory portion of the beam, then it is indicative of an undamaged window. This advantageously prevents dangerous beam generated damage which may be caused if the exit window of the transmitter is damaged. The laser beam is preferably circularly polarized before exiting the transmitter to prevent dangerous laser damage caused by the reflections of the maximum of the P or S polarization components, which may occur with linearly polarized beams.

Safe enclosures for wireless power supply

Methods and systems for safely and effectively supplying a beam of wireless power from a transmitter to at least one receiver. A delta signal is generated by repeatedly calculating the difference in power between the power of the beam emitted by the transmitter and the amount of power received at the receiver. The system dynamically generates a time delay, which is a time period shorter than the maximal exposure duration relating to safe exposure durations for the power level of the delta signal. If the time delay is exceeded, the system changes an operational parameter of the system, such as terminating the beam. Because of limitations to building a perfect timing system, the system is built to be more sensitive to time delays having longer safe exposure durations, with large delta signals having short safe exposure durations being responded to immediately and without significant regard to the time delay.

Wireless power transmission system with adaptive dynamic safety management

A safety supervision system for wireless power transmission, comprising a transmitter having an optical beam generator with safe states for transmitting power to receivers that convert the beam into electrical power. The system control unit stores previously known signatures categorized by predetermined parameters associated with one or more unwanted situations, stores data from sensors, compares this stored data to the signatures, and executes one or more responses based on this comparison. The system may comprise transmitter and/or receiver malfunction detection systems adapted to monitor the transmitter and receiver control units and to cause the optical beam generator to switch to a safe state upon detection of a transmitter or receiver control unit malfunction, and may further comprise a hazard detection system preventing human exposure to beam intensity above a predefined safe level.

Flexible management system for optical wireless power supply

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.

Multiple beam wireless power transmission system

A wireless power transmitter system for directing a high energy beam towards receivers fitted with identifying signs. One type of the identifying signs may have asymmetric shape properties, such that their mirror image cannot be matched to their actual shape, even after the image is rotated, tilted or otherwise geometrically manipulated. The system can thus determine whether a detected image of a sign is a true image received directly from said receiver, or is received after the imaged beam has undergone a reflection between the receiver and the transmission system. In the latter case, the system can prevent high power transmission from being directed to a location other than a real receiver, which could be a safety hazard. Other types of identifying signs may be located in or on the borders of different zones of a transmission space, to identify zones where transmission may be allowed or prohibited.
