- a shaping of the energy beam 1.4.1 into the shaped beam 1.5.2 by means of the beam shaping 1.5 here includes, for example, a beam widening, broadening or scattering.
- the shaping of the energy beam 1.4.1 into the shaped beam 1.5.2 by means of the beam shaping 1.5 includes, for example, a beam narrowing, concentration or bundling.
- the energy beam is shaped in such a way that it has the best possible overlap when it strikes an energy converter 2.1 of the receiver 2 (see FIG. 2). This can be used not only when using coherent radiation, but also when using non-coherent radiation and is an essential element of the solution presented.
- Part of an (optionally) implemented safety device is a protection going dismantling of the laser device 1.4 or destruction / dismantling of the beam shaping 1.5 or 1.5.1. This is achieved, for example, by sensors or by an interrupting power supply line that deactivates the laser 1.4 when dismantled and thus prevents the leakage of impermissible power levels 1.4.1.
- part of the laser device 1.4 is also a receiver / demodulator 1.4.2 for radiation of the same wavelength, which can receive and demodulate the components reflected from the environment.
- Another element is a mechanical actuator or motor 1.6, which can control the direction of the energy beam 1.4.1 or 1.5.2.
- electric motors or piezomotors can be used, which act on the radiation source 1.4 or the optical elements 1.5 or 1.5.1 or both.
- non-mechanical controls of the energy beam can be used, which work with the control of the direction by superposition of several radiation sources or with the control of the refractive index in optical media.
- Another element of this embodiment is a camera 1.7 which records images of the surroundings.
- the surroundings can optionally be illuminated with an infrared light source 1.9 if the ambient light is insufficient.
- Another optional element is a radio transceiver 1.8, which can send and receive information.
- algorithms of the pattern recognition 1.3 are also used in order to evaluate the images that the camera 1.7 records of the environment, possibly using the infrared light source 1.9.
- the algorithms of the pattern recognition 1.3 are stored, for example, in the form of executable programs or software.
- microcontroller 1.2 Another essential element is a microcontroller 1.2, which here, for example, performs all the tasks of regulating and controlling the individual components or executing programs or software, and in particular data streams from the camera 1.7, the radio transceiver 1.8 and the backscattered signals from the laser from the demodulator 1.4.2 can handle.
- the microcontroller is also set up, for example, to execute the pattern recognition algorithms 1.3.
- the algorithms of the pattern recognition 1.3 are designed, for example, so that a) human persons and pets can be distinguished from the environment and / or b) in particular the position of the eyes can be identified and / or c) markers that are on the receiving device (see figure 2) can be recognized.
- Figure 2 shows essential elements of the energy receiver (energy receiver) 2.
- So 2.1 is an energy converter, which converts the received radiation (the received energy beam 1.4.1 or 1.5.2) into electrical energy.
- photovoltaic cells that are optimized for the wavelength of the radiation can be used, e.g. GaAS solar cells that have been optimized for wavelengths of 850 nm.
- reflectors 2.3 are optionally arranged, the degree of reflection of which can be electrically controlled or modulated. This is possible, for example, in a particularly energy-saving way using LCD elements.
- the energy converter 2.1 is circular, with a plurality of reflectors 2.3 being arranged in a circle surrounding the energy converter 2.1. In other implementations, alternative arrangements of the reflectors 2.3 are provided.
- optical markers 2.2 are located on the device 2 and which can be easily identified by the remote camera 1.7 of the energy transmitter 1 (see FIG. 1 and the explanations above). These markers 2.2 can be designed through their mechanical shape, colors, printing with patterns and / or digital codes, reflectors (static or modulatable) and / or through the use of light sources (invisible or visible spectrum).
- An electronic circuit 2.4 which takes over the charge management of an energy store 2.5, is assigned to the energy converter 2.1.
- this energy store 2.5 forms the essential energy source for the device which is equipped with the radiation receiver / energy receiver 2 and is to be operated, which device has additional functions via the collection of energy.
- element 2.7 is a dedicated electronic circuit 2.7, which has the advantage of particularly low power consumption and also works with an empty energy store 2.5 and possibly without the use of a microcontroller / controller 2.6 as soon as energy arrives at the solar cell / energy converter 2.1. In alternative implementations, this function of element 2.7 is taken over by microcontroller 2.6. Element 2.7 can be omitted here.
- the energy receiver 2 has a radio transceiver 2.8, which can exchange data with the transceiver 1.8 of the energy transmitter 1 (see FIG. 1 and the above explanations).
- FIG. 3 shows a method for energy transmission in a flow chart. The essential steps shown are typically run through, e.g. when operating a system made up of an energy transmitter 1 (see FIG. 1) and an energy receiver 2 (see FIG. 2) of the type explained above.
- the camera 1.7 When the energy transmitter 1 is switched on, the camera 1.7 is first activated. This provides images of the surroundings, which are analyzed with the aid of the image processing algorithms 1.3. In particular, the following information is obtained:
- a set of criteria that must be met before the laser 1.4 can be activated is then checked. This includes at least the presence of the markers 2.2 and a sufficient safety distance between the position of the energy converter / solar cell 2.1 of the energy receiver 2 and the eyes of humans and animals.
- Modified algorithms 1.3 can also be used, which allow objects that have once been identified to be tracked as they move in space.
- the examination of the criteria is continued periodically, regardless of the result, with a time criterion guaranteeing that a) the positions of the objects in the room cannot yet have changed significantly, and / or b) due to the shortness of the time, no dangerous exposure, in particular of the Eyes can take place.
- the laser 1.4 is aimed at the position determined by the marker 2.2 and activated.
- the modulatable reflectors 2.3 which surround the energy converter 2.1 of the energy receiver 2, reflect the energy beam 1.4.1 or 1.5.2 as soon as they are hit by it. These reflections are received and evaluated by the receiver of the reflected components, for example in particular component 1.4.2, which is structurally arranged in the vicinity of the transmitter (laser 1.4) and the camera 1.7. This means that the precise overlap of the energy beam 1.4.1 or 1.5.2 with the energy converter 2.1 getting closed. This information is used for the continuous readjustment of the direction of the energy beam 1.4.1 or 1.5.2 by the beam control of the transmitter (laser 1.4). The beam control takes place, for example, via component 1.6 and / or component 1.5.
- the closer environment of the calculated position of the energy converter 2.1 can be scanned with the energy beam 1.4.1 or 1.5.2, until corresponding modulations show up and indicate the exact position.
- FIG. 4 illustrates an application example of the components, systems and methods explained above using a game controller.
- FIG. 4 illustrates the general spatial arrangement of the components using the energy transfer application example for a game controller 3.4, which controls a game console 3.5, the images of which are displayed on a screen 3.3.
- essential parts of the energy transmitter / the energy transmission device 1 are accommodated here, for example, in the vicinity of the screen 3.3, but can generally also be integrated into other devices, such as the game console 3.5 or the screen 3.3.
- the energy transmission device 1 has the functional blocks described in more detail in FIG. 1 and explained above, here visible in FIG. 4 the camera (see 1.7 in FIG. 1) and radiation source (see 1.4 / 1.5 in FIG ) Emits and aligns energy beam 1.4.1 or 1.5.1.
- the position of people 3.1, pets 3.2 and, in particular, their eyes is recognized and taken into account.
- the position of the eyes is important because, in principle, an energy beam 1.4.1 or 1.5.1, a harmless power density, can be bundled with optical aids such as lenses, mirrors, telescopes, etc. over a large area.
- Even with covered eyes if, for example, a person were looking into the radiation source with binoculars, their position in relation to the body is recognizable or known with the above measures and features, and energy transmission device 1 can prevent energy from being emitted.
- the game controller 3.5 is the energy-receiving device 2 in this example. It has markers 2.2 attached to the outside which, due to their particularly high contrast, can be recognized easily and with high accuracy by the image recognition algorithms 1.3 of the energy transmitter 1. This allows a quick and precise localization of the game controller 3.5 in the plane / in the room. Furthermore, it is possible, for example, by evaluating the transit time of short light pulses or by using differently / variably modulated light, to determine the distance between the markers 2.2 and the camera 1 (see 1.7 in FIG. 1).
- the energy transfer are started, the energy beam 1.4.1 or 1.5.2 hitting the photovoltaic cell / energy converter 2.1 and the exact alignment of the energy beam
- I.4.1 or 1.5.2 can be readjusted by evaluating the portions of the energy beam 1.4.1 or 1.5.2 modulated by the reflectors 2.3 (see FIG. 2 and the explanations above). Compared with the evaluation of the position by the camera 1 (see 1.7 in FIG. 1), this evaluation is significantly faster and also allows rapid movements of the controller 3.4 to be followed without the energy supply being interrupted.
- Radio sensors and radio actuators that transmit their data or action commands by radio are already widely used today.
- the energy supply is a critical point, especially when battery changes are expensive (difficult access) or no ambient energy is available (especially insufficient light).
- Radio sensors on moving or rotating machine parts which measure e.g. forces, torque, distance, temperatures;
- Radio sensors that monitor and report the level of goods in production logistics or warehousing, e.g. by tracking carriers for goods on assembly lines or in high-bay warehouses;
- Radio sensors which are mounted on vehicles such as cars or rail vehicles, and which are supplied with energy by stationary mounted energy transmitters, and then make data on the identity and condition of the transport vehicles readable as they drive past;
- Wireless sensors / wireless actuators that process access information and / or lock / unlock access systems. This means, for example, radio sensors in doors that report the status of the door (open, closed, locked), but can also be instructed by radio to lock or unlock a door using electromechanical actuators.
- Cell phones, mobile computers and similar devices can be charged with the components, systems and methods described above, without cables having to be plugged in and / or without the need for precise positioning on charging mats or charging docks, for example.
- the energy transmitter 1 can be attached to the ceiling in a central location, for example.
- Wearables such as fitness trackers, medical devices, smartwatches, hearing aids, electronic glasses with video function, virtual reality glasses or electronics that are connected to clothing can be supplied with energy using the components, systems and methods described above. This is particularly useful if an infrastructure is installed on energy transmitters 1 at the locations where this use is necessary or particularly likely.
