In some embodiments, power emitting unit 92,94 can share the common energy.Such as, single laser or other electromagnetic beam source (not shown) can illuminate multiple optical fiber or other energy conduit, its by energy " conveying " to power emitting unit 92,94 for from be physically separated some transmission.
Fig. 6 shows the flow chart comprising the operation of the system of multiple power emitting unit of all systems as shown in Figure 5.As shown in step 120, broadcsting transmitter 96 broadcasts the signal of indicated horsepower availability.In some embodiments, this broadcast can in response to trigger element (not shown), and it signals to enter the Signal reception of conditioned disjunction in response to such as internet transmissions in room in response to such as people can to broadcsting transmitter 96 or the request from receiving element is broadcasted.As indicated in step 122, in response to this broadcast, receiver 98 is from the request of receiving element received power.As mentioned above, this request can with the form directly transmitted, or it can be the reflection (modulating alternatively) of broadcast singal.As shown in step 124, the one or more power emitting unit 92,94 of Systematic selection with in response to request (such as, the operation by identifying unit 100), and from selected unit transmitting power as shown in step 126.In some embodiments, the preferred power emitting unit of receiver 98 identifiable design pass on power request from one or more discrete cell.
Fig. 7 is the flow chart that the operation power be launched being fed to the system of multiple receiving element is shown.This system can comprise single power emitting unit as shown in Figure 1, or multiple power emitting unit as shown in Figure 5.As shown in step 130, the signal of system broadcasts indicated horsepower availability.As shown in step 132 and 134 respectively, system responses is in broadcast reception first power request and the second power request.As shown in step 136, the relative priority of power request that then system is determined (such as, by the operation of identifying unit).Such as, system can select the power request generating maximum return or profit, or it can select the power request that can be served most effectively by system, or it can select power request according to other appropriate criteria any.Choice criteria can comprise the reference of data of supplying the receiving element of one or two request, the identifying information of the distribution of the quantity of such as power type, wavelength, pulse characteristics, power, polarization, power over time, time window, acceptable price, ability to pay, payment mode or receiving element.As shown in step 138 and 140, then system selects power emitting unit by power emission to higher priority request end (if system comprises multiple power emitting unit), but also can select power emitting unit by power emission to lower priority request end.These power beams can be derived from power emitting unit that is identical or that be separated, and in some embodiments, power can be fed to same receiver by more than one power emitting unit.As shown in step 142, power is transmitted into the receiving element of request by system from selected power emitting unit.
Fig. 8 is the schematic diagram of the power beam system of carrying the power beam surrounded by protection beam in fact.Power emitting unit 160 is arranged to supply with the power of the form of power beam 162 (such as, laser beam), and protection transmitter unit 164 is arranged to produce protection beam 166.In the embodiment shown, these beams are combined as conllinear in fact in beam combiner 168.Therefore wider protection beam 166 surrounds (with imbrication alternatively) narrower power beam 162.Beam combiner 168 can be omitted, if power emitting unit 160 and protection transmitter unit 164 are arranged to produce the beam geometry expected.Such as, protection transmitter unit 164 can comprise the multiple protection beam generator be arranged in around power emitting unit 160, to produce the overlap or non-overlapped protection beam 166 of jointly surrounding power beam 162.
The beam of combination is directed into power receiver 170, and wherein reflecting back at least partially of beam protects beam receiver 172.In some embodiments, power receiver 170 can be arranged to from power beam 162 than the power absorbing greater part in fact from protection beam 166, the power of greater part is in fact reflected (such as from protection beam 166, compare with power beam 162, protection beam 166 can at the frequency place of the non-absorbing of receiver 170).In the embodiment shown for the sake of clarity, reflection path and course of the beam are a little at angle, but reflection also such as by the close original course of the beam in power receiver 170 place use retroreflector, or can arrive protection beam receiver 172 at calculated any selected angle place.
Power beam 162 is incited somebody to action usually (but not necessarily) there is the power density higher than protection beam 166.In addition, beam can (but not needing) in wavelength, polarity, modulation or characteristic aspect difference (such as, electromagnetic power beam harmony protection beam).If different in any one in these features of beam, different features can be used for distinguishing the shock on protection beam 166 and the shock on power beam 162, as discussed further in conjunction with Figure 10 and Figure 11.In addition, protection beam 166 needs not be similar, and the position of clashing into can be inferred from the feature of reflected signal.Such as, the beam that beam 166 can comprise the multiple different frequencies be arranged in around power beam 162 is protected.By monitoring which frequency or which frequency is interrupted, one or more features of impacting object can be inferred, such as speed, direction, size, shape or composition.Such as, when this Information Availability will leave course of the beam in prediction object and allows restarting of power beam 162.Similarly, protection beam 166 can be by the relatively narrow beam of rapid scanning (or around power beam 162 by a series of narrow protection beam illuminated continuously) around power beam 162, instead of the broad-beam condition of continuous encirclement power beam 162 as shown in Figure 8.In this embodiment, the feature of impacting object can be determined by the Annual distribution of monitoring protection beam intensity.Protection beam 166 also can comprise multiple protection beam concentric in fact.In some this execution modes, the shock on exterior protection beam can warn power emitting unit 160 prepare suspend transmission, and if internal Protection beam be also knocked, transmission can suspend or stop.
Protection beam receiver 172 is monitored by the protection beam 166 reflected.If change feature in some way from the quantity of protecting the energy that beam 166 receives; may clash into (such as on instruction beam; beam power declines), decision circuit 174 can instruct power emitting unit 160 to suspend or stop the transmission of power beam 162.Because protection beam 166 surrounds power beam 162 in fact, object or person are crossing with power beam and before possible sustain damage, power can be cut off in response to the shock protecting beam.Alternatively, be not the transmission suspending power beam 162, system can reset the route of power beam, to avoid impacting object.Such as, in the embodiment shown, the beam of combination can be directed to beam induction element 176 (in the embodiment shown, being speculum) by beam combiner 168, and the beam of combination is redirected to power receiver 170 by this beam induction element 176.In some embodiments, multiple protection beam receiver (not shown) can be had.Additionally or alternatively, also be may be used for the quality of monitoring power delivery by the protection beam 166 reflected.Such as, if protection beam 166 only reflects on side, it can not to be directed pointing power receiver 170 by indicated horsepower beam 162, or the shape of beam spot should be adjusted, with the apparent shape of mesh power receiver 170 (this can change according to receiver attitude).
In some embodiments, can be produced by retroreflector by the cylindrical geometries of the protection beam 166 reflected.Such as, the non-collimated light source at power emitting unit 160 place can reflect back into unit by retroreflector array (such as, 3M ScotchliteTM).The retroreflector array surrounding main power receiver target also can be reflected back the edge of power beam 162, to serve as by the protection beam 166 reflected.In some embodiments, the retroreflector at power receiver place can have the diacritic space structure allowing the feature of impacting object or the deduction of geometry.
