     DETAILED DESCRIPTION 
     According to various embodiments, a position of a wireless power receiver in a network of interlinked prescribed paths is tracked as the wireless power receiver traverses one or more prescribed paths in the network of interlinked prescribed paths.

     In certain embodiments, a system includes one or more wireless power transmitters for wirelessly transmitting energy to a wireless power receiver.

The position of the wireless power receiver is tracked as the wireless power receiver traverses one or more prescribed paths in the network of interlinked prescribed paths for purposes of wirelessly transmitting the energy to the wireless power receiver. 
     In various embodiments, a position of a wireless power receiver in a network of interlinked prescribed paths is tracked as the wireless power receiver traverses one or more prescribed paths in the network of interlinked prescribed paths.

     The example wireless power receivers described herein can be configured to wirelessly receive energy through RF signals.

Specifically, received RF energy can be received at a wireless power receiver through a beam of RF energy steered using a phased array of antennas. A beam of RF energy received by a wireless power receiver, e.g. a beam of energy used to transmit power, can be steered based on a position of the wireless power receiver.

     As will be discussed in greater detail later, the wireless power transceivers described herein can transmit RF energy as part of a steerable beam of RF energy. For example, the wireless power transceivers described herein can transmit energy as part of an energy carrying signal at a specific RF frequency or within a specific RF frequency band. Specifically, RF energy can be transmitted by a wireless power transmitter through a beam of RF energy steered using a phased array of antennas.

More specifically, a wireless power receiver can move and a beam of RF energy transmitted to the wireless power receiver can be steered by a wireless power transmitter towards the wireless power receiver as it moves, e.g. in a network of interlinked prescribed paths. 
     Some of the infrastructure that can be used with embodiments disclosed herein is already available, such as general-purpose computers, antennas, computer programming tools and techniques, digital storage media, and communications networks.

     Various aspects of certain embodiments may be implemented using hardware, software, firmware, or a combination thereof. As used herein, a software module or component may include any type of computer instruction or computer executable code located within or on a computer-readable storage medium. A software module may, for instance, comprise one or more physical or logical blocks of computer instructions, which may be organized as a routine, program, object, component, data structure, etc., that performs one or more tasks or implements particular abstract data types. 
     In certain embodiments, a particular software module may comprise disparate instructions stored in different locations of a computer-readable storage medium, which together implement the described functionality of the module. Indeed, a module may comprise a single instruction or many instructions, and may be distributed over several different code segments, among different programs, and across several computer-readable storage media.

     The embodiments of the disclosure will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. The components of the disclosed embodiments, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Furthermore, the features, structures, and operations associated with one embodiment may be applicable to or combined with the features, structures, or operations described in conjunction with another embodiment. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of this disclosure. 
     Thus, the following detailed description of the embodiments of the systems and methods of the disclosure is not intended to limit the scope of the disclosure, as claimed, but is merely representative of possible embodiments. In addition, the steps of a method do not necessarily need to be executed in any specific order, or even sequentially, nor need the steps be executed only once. 
       FIG. 1  illustrates an example system  100  for transmitting and receiving energy wirelessly. The system  100  includes a wireless power transmitter  102  and a wireless power receiver  104 . The wireless power transmitter  102  functions according to an applicable device for wirelessly transmitting energy, e.g. as part of wirelessly transmitting power, such as the wireless power transmitters described herein. Specifically, the wireless power transmitter  102  can wirelessly transmit energy through a beam of energy, e.g. RF energy. Further, the wireless power transmitter  102  can transmit energy through a steerable beam of RF energy, e.g. as part of an energy carrying signal at a specific RF frequency or within a specific RF frequency band. Specifically, the wireless power transmitter  102  can transmit RF energy in a steerable beam using a phased array of antennas. 
     The wireless power transmitters described herein, including the wireless power transmitter  102 , can transmit multiple beams of energy, e.g. for purposes of wirelessly transmitting power. Specifically, the wireless power transmitters described herein can each simultaneously broadcast multiple beams of energy, e.g. for purposes of wirelessly transmitting power to one or more wireless power receivers. For example, the wireless power transmitter  102  can simultaneously broadcast a first beam of energy and a second beam energy for wirelessly transmitting energy to a wireless power receiver. In another example, the wireless power transmitter  102  can simultaneously broadcast a first beam of energy for wirelessly transmitting energy to a first wireless power receiver and a second beam of energy for wirelessly transmitting energy to a second wireless power receiver. 
     The wireless power receiver  104  functions to receive energy wirelessly from the wireless power transmitter  102 , e.g. as part of wirelessly receiving power. The wireless power receiver  104  can move as it receives wireless energy. Specifically, the wireless power receiver  104  can be configured to move itself or integrated as part of a moveable device for moving the wireless power receiver  104  as the wireless power receiver  104  receives wireless energy. The wireless power receiver  104  can move terrestrially. For example, the wireless power receiver  104  can be integrated as part of a land vehicle for movement along land. Further, the wireless power receiver  104  can move aerially. For example, the wireless power receiver  104  can be a drone that is configured to fly through the air. 
     The wireless power receiver  104  can move along a network of interlinked prescribed paths  106 . A prescribed path, as used herein, can include a pre-defined path or route that is known before a wireless power receiver traverses all or a portion of the path. For example, a portion of a prescribed path can include a 45° turn twenty feet from the beginning of the path, which is known before a wireless power receiver makes the turn in traversing the prescribed path. While the network of interlinked prescribed paths  106  shown in  FIG. 1  is curved, in various embodiments, the network of interlinked prescribed paths  106  can include an applicable number of either or both curved and straight prescribed paths. A prescribed path in a network of interlinked prescribed paths can be represented along one dimension in three-dimensional Euclidian space, along two dimensions in three-dimensional Euclidean space, or along three dimensions in three-dimensional Euclidian space. 
       FIG. 2  shows an example network of interlinked prescribed paths  200 . The example network of interlinked prescribed paths  200  includes a first prescribed path  202 , a second prescribed path  204 , and a third prescribed path  206 . The first prescribed path  202  and the third prescribed path  206  can be straight or substantially straight prescribed paths, e.g. straight in three dimensions in three-dimensional Euclidian space. Further, the second prescribed path  204  can be a curved prescribed path, e.g. curved in three dimensions in three-dimensional Euclidian space. 
     The first prescribed path  202 , the second prescribed path  204 , and the third prescribed path  206  are interlinked to form the network of interlinked prescribed paths  200 . More specifically, the first prescribed path  202 , the second prescribed path  204 , and the third prescribed path  206  are physically connected, as part of being interlinked, to form the network of interlinked prescribed paths  200 . In being physically connected, an applicable combination of the first prescribed path  202 , the second prescribed path  204 , and the third prescribed path  206  can overlap, at least in part, in space. More specifically, an applicable combination of the first prescribed path  202 , the second prescribed path  204 , and the third prescribed path  206  can overlap to effectively form a single prescribed path as part of the network of interlinked prescribed paths  200 . For example, the first prescribed path  202  can overlap with the second prescribed path  204  to physically connect the first prescribed path  202  and the second prescribed path  204  and form, at least in part, the network of interlinked prescribed paths  200 . Further in the example, the second prescribed path  204  can overlap with the third prescribed path  206  to physically connect the second prescribed path  204  and the third prescribed path  206  and form, at least in part, the network of interlinked prescribed paths  200 . 
     A wireless power receiver, as will be discussed in greater detail later, can receive energy wirelessly from one or more wireless power transmitters as it moves along the network of interlinked prescribed paths  200 . Specifically, a wireless power receiver can receive energy wirelessly at it moves along physical connections between one or a combination of the first prescribed path  202 , the second prescribed path  204 , and the third prescribed path  206  forming the network of interlinked prescribed paths  200 . 
       FIG. 3  shows another example network of interlinked prescribed paths  300 . The example network of interlinked prescribed paths  300  includes a first prescribed path  302  and a second prescribed path  304 . Either or both the first prescribed path  302  and the second prescribed path  304  can be formed by a plurality of interlinked prescribed paths. Specifically, either or both the first prescribed path  302  and the second prescribed path  304  can be formed by a plurality of prescribed paths that are interlinked through physical connections. For example, the first prescribed path  302  can be formed by a plurality of prescribed paths that overlap, at least in part, to physically connect the plurality of prescribed paths to form the first prescribed path  302 . 
     The first prescribed path  302  and the second prescribed path  304  are interlinked to form the network of interlinked prescribed paths  300 . Specifically, the first prescribed path  302  and the second prescribed path  304  are physically separated, e.g. by a gap, and are grouped together to form the network of interlinked prescribed paths  300 . Physically separated prescribed paths can be grouped together or otherwise interlinked to form a network of interlinked prescribed paths  300  based on physical locations of the prescribed paths within space. For example, a prescribed path adjacent to a first prescribed path can be grouped with or otherwise interlinked with the first prescribed path to form a network of interlinked prescribed paths. Further, physically separated prescribed paths can be grouped together to form a network of interlinked prescribed paths based on whether a wireless power receiver can move between the physically separated prescribed paths as it traverses the network of interlinked prescribed paths. For example, if a wireless power receiver can power itself as it moves between two physically separated prescribed paths, then the physically separated prescribed paths can be interlinked to form a network of interlinked prescribed paths. 
     A wireless power receiver, as will be discussed in greater detail later, can receive energy wirelessly from one or more wireless power transmitters as it moves along the network of interlinked prescribed paths  300 . Specifically, a wireless power receiver can receive energy wirelessly at it moves along either of the physically separated first prescribed path  302  and second prescribed path  304  of the network of interlinked prescribed paths  300 . 
     Further, a wireless power receiver can power itself as it moves between the physically separated first prescribed path  302  and the second prescribed path  304 . Specifically, a wireless power receiver can include a power source, e.g. a battery, that is configured to power the wireless power receiver as the wireless power receiver moves from the first prescribed path  302  to the second prescribed path  304  across a gap that physically separates the first prescribed path  302  and the second prescribed path  304 . For example, a wireless power receiver can receive wireless energy from one or more wireless power transmitters as it traverses the first prescribed path  302 . Further in the example, the wireless power receiver can power itself, e.g. using a battery, as it moves across a gap from the first prescribed path  302  to the second prescribed path  304 . Still further in the example, the wireless power receiver can then receive wireless energy from one or more wireless power transmitters once it moves into the second prescribed path  304  and begins traversing the second prescribed path  304 . 
       FIG. 4  shows an example prescribed path  400 . The prescribed path  400  includes a plurality of designated lanes. The prescribed path  400  shown in  FIG. 4  can be implemented as part of an applicable network of interlinked prescribed paths that a wireless power receiver can traverse, such as the network of interlinked prescribed paths shown in  FIGS. 2 and 3 . Specifically, the prescribed path  400  can be physically connected to another prescribed path to form, at least in part, a network of interlinked prescribed paths. Alternatively, the prescribed path  400  can be physically separate from another prescribed path, but grouped with the other prescribed path to form a network of interlinked prescribed paths. 
     The prescribed path  400  includes a first designated lane  402 - 1 , a second designated lane  402 - 2 , a third designated lane  402 - 3 , and a fourth designated lane  402 - 4  (herein collectively referred to as “designated lanes  402 ”). The designated lanes  402  can be defined by a region of space with the prescribed path  400 . For example, each of the designated lanes  402  can have a set width within the prescribed path  400 . In another example, each of the designated lanes  402  can have a set length along the prescribed path  400 . 
     The designated lanes  402  can support traversal of one or more wireless power receivers as the one or more wireless power receivers move along the prescribed path  400 , e.g. in a network of interlinked prescribed paths. Specifically, a single wireless power receiver can move along or within a lane of the designated lanes  402  as the wireless power receiver traverses the prescribed path  400 . More specifically, a lane of the designated lanes  402  can be separated for traversal by a single line, e.g. single file, of wireless power receivers as the wireless power receivers traverse a network of interlinked prescribed paths using the lane. Further, a wireless power receiver can switch between the lanes  402  as the wireless power receiver traverses the prescribed path  400 . For example, a wireless power receiver can move from the first lane  402 - 1  to the second lane  402 - 2  as the wireless power receiver traverses the prescribed path  400 , e.g. as part of traversing a network of interlinked prescribed paths. 
     In supporting traversal of wireless power receivers as the wireless power receivers traverse the prescribed path  400 , the designated lanes  402  can support concurrent traversal of the wireless power receivers. Specifically, a first wireless power receiver can traverse the first designated lane  402 - 1  as a second wireless power receiver traverse the second designated lane  402 - 2 . More specifically, the first wireless power receiver can concurrently traverse the first designated lane  402 - 1  as the second wireless power receiver traverses the second designated lane  402 - 2  and energy is concurrently transferred to the receivers wirelessly as the receivers traverse the first designated lane  402 - 1  and the second designated lane  402 - 2 . 
     While the prescribed path  400  is shown to have four designated lanes, a prescribed path, as described herein, can include more or fewer lanes. Further, while the lanes  402  are shown to be adjacent to each other, in various embodiments, the lanes  402  can intersect each other and/or extend away from each other. Further, the lanes  402  can extend across a plurality of different prescribed paths. For example, the first lane  402 - 1  can extend into another prescribed path that is physically connected to the prescribed path  400 . In another example, the second lane  402 - 2  can extend into another prescribed path that is physically separated from the prescribed path  400 . 
     Referring back to the example system  100  shown in  FIG. 1 , the wireless power transmitter  102  can wirelessly transmit energy to the wireless power receiver  104  based on a position, e.g. a tracked position, of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . For example, a beam of energy can be broadcast towards a current position of the wireless power receiver  104  in the network of interlinked prescribed paths in order to wirelessly transfer energy to the wireless power receiver  104 . Similarly, the wireless power receiver  104  can receive wirelessly transferred energy based on a position, e.g. a tracked position, of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . For example, the wireless power receiver  104  can wirelessly receive energy from a beam of energy broadcast towards the wireless power receiver  104  based on a position of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . A position of the wireless power receiver  104  in the network of interlinked prescribed paths  106  can include one or a combination of a specific prescribed path where the wireless power receiver  104  is located, a region within the prescribed path where the wireless power receiver  104  is located, and a specific lane within the prescribed path where the wireless power receiver  104  is located. 
     A position of the wireless power receiver  104  within the network of interlinked prescribed paths  106  can change as the wireless power receiver  104  traverses the network of interlinked prescribed paths  106 . Accordingly, the changing position of the wireless power receiver  104  within the network of interlinked prescribed paths  106  can be actively tracked as wireless power receiver  104  traverses the network of interlinked prescribed paths  106 . As follows, the wireless power transmitter  102  can wirelessly transmit energy to the wireless power receiver  104  based on an actively tracked position, e.g. a changing position, of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . For example, a beam of energy can be broadcast towards a changing position of the wireless power receiver  104  in the network of interlinked prescribed paths in order to wirelessly transfer energy to the wireless power receiver  104 . Similarly, the wireless power receiver  104  can receive wirelessly transferred energy based on an actively tracked position, e.g. a changing position, of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . For example, the wireless power receiver  104  can wirelessly receive energy from a beam of energy broadcast towards a changing position of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . 
     Further, the wireless power transmitter  102  can transmit beams of energy to the wireless power receiver  104  traversing the network of interlinked prescribed paths  106  based on the fact that the prescribed paths are pre-defined paths. Specifically, the wireless power transmitter  102  can be configured and/or positioned to transmit beams of energy to specific portions of the network of interlinked prescribed paths  106  based on a pre-defined location and length of a prescribed path in the network of interlinked prescribed paths  106 . For example, with reference to the network of interlinked prescribed paths  200  shown in  FIG. 2 , the wireless power transmitter can be positioned in proximity to the first prescribed path  202  in order to transmit beams of energy to wireless power receivers traversing the first prescribed path  202  as they traverse the network of interlinked prescribed paths  200 . 
     In transmitting wireless energy to a wireless power receiver based on a position of the receiver in a network of interlinked prescribed paths, one or a plurality of wireless power transmitters can transmit wireless energy to the receiver based on a lane traversed by the receiver. Specifically, one or more wireless power transmitters can wireless transmit energy to a wireless power receiver as the receiver switches between different lanes of a network of interlinked prescribed paths. For example, as will be discussed in greater detail later, a wireless power transmitter can switch a beam of energy across different lanes of a network of interlinked prescribed paths as a wireless power receiver changes between the different lanes. In another example, a wireless power transmitter can broadcast a beam of energy that extends across different designated lanes to wirelessly transfer energy to a wireless power receiver as it switches between the different designated lanes. In yet another example, each designated lane can have a corresponding wireless power transmitter configured to broadcast a beam of energy along each designated lane. Subsequently, the different wireless power transmitters can provide wireless energy to a wireless power receiver as it switches between corresponding designated lanes of the wireless power transmitters. 
       FIGS. 5A-F  illustrate different beam patterns of one or more beams of energy broadcast to wirelessly transfer energy to one or more wireless power receivers traversing a network of interlinked prescribed paths  500 . The network of interlinked prescribed paths  500  discussed with reference to the beam patterns shown in  FIGS. 5A-F  includes a first prescribed path  502  and a second prescribed path  504 . 
     The example beam pattern shown in  FIG. 5A  includes a main lobe  506  of a beam of energy for wirelessly transferring energy to a wireless power receiver. While the main lobe  506  is shown to extend beyond the first prescribed path  502 , in various embodiments, the main lobe  506  can be wholly contained within the first prescribed path  502 . Alternatively, the main lobe  506  can extend into the second prescribed path  504  to cover at least a portion of both the first prescribed path  502  and the second prescribed path  504 . Specifically, the main lobe  506  can have a width greater than a width of the first prescribed path  502 . 
     The main lobe  506  can be swept along the first prescribed path  502  in order to wirelessly transfer energy to a wireless power receiver traversing the first prescribed path  502 . Specifically, a wireless power transmitter can control a beam of energy to sweep the corresponding main lobe  506  of the beam of energy along the first prescribed path  502 . The main lobe  506  can be swept along the first prescribed path  502  according to a set manner. For example, the main lobe  506  can be swept along the first prescribed path  502  at a constant pre-defined speed. Further, while the main lobe  506  is shown as moving along the first prescribed path  502  in a single direction, in various embodiments, the main lobe  506  can move in multiple directions within the first prescribed path  502 . For example, the main lobe  506  can be swept back and forth across a width of the first prescribed path  502 . 
     A position of a wireless power receiver traversing the first prescribed path  502  can correspond to a position of the main lobe  506  in the first prescribed path  502  as the main lobe  506  is swept along the first prescribed path  502 .

       FIGS. 6A-C  illustrate different beam patterns of one or more beams of energy broadcast to wirelessly transfer energy to one or more wireless power receivers traversing a prescribed path  600  based on designated lanes. Specifically, the prescribed path  600  includes a first designated lane  602  and a second designated lane  604 . The designated lanes described herein can have a corresponding traffic flow direction along which wireless power receiver traverse when traversing the designated lanes. For example, both the first designated lane  602  and the second designated lane  604  can have the same traffic flow direction such that wireless power receivers move along the same direction when traversing the first designated lane  602  and the second designated lane  604 . Alternatively, the first designated lane  602  and the second designated lane  604  can have opposite traffic flow directions. As a result, wireless power receivers can move in opposite directions of each other when traversing the corresponding first designated lane  602  and the second designated lane  604 . 
     In having a traffic flow direction, one or more wireless power transmitters associated with a designated lane can be configured to broadcast a beam of energy along the designated lane in the traffic flow direction of the designated lane. For example, a wireless power transmitter can be configured to broadcast a beam of energy in a specific designated lane, and the wireless power transmitter can be configured to broadcast the beam of energy along the traffic flow direction of the specific designated lane. Accordingly, a wireless power receiver can be configured to receive wireless energy broadcast along a traffic flow direction of a designated lane traversed by the wireless power receiver. Specifically, a wireless power receiver traversing a specific designated lane can be configured to receive a beam of energy broadcast by a transmitter according to the traffic flow direction of the specific designated lane. 
     The beams of energy discussed with respect to the beam patterns shown in  FIGS. 6A-C  can include one main lobe. For example, a beam of energy broadcast in the first designated lane  602  can include a single main lobe. Alternatively, the beams of energy discussed with respect to the beam patterns shown in  FIGS. 6A-C  can include one or a combination of one main lobe, a plurality of main lobes, one grating lobe, and a plurality of grating lobes. For example, a beam of energy broadcast in the second designated lane  604  can include a main lobe and a plurality of grating lobes. In another example, a beam of energy broadcast in the second designated lane  604  can include a plurality of main lobes. 
     While each beam discussed in conjunction with each beam pattern in  FIGS. 6A-C  are represented and discussed as a single beam of energy, in various embodiments, each beam can actually represent a plurality of beams. Specifically, each beam discussed in conjunction with each beam pattern in  FIGS. 6A-C  can include a plurality of beams broadcast by one or more wireless power transmitters. 
     The example beam pattern shown in  FIG. 6A  includes a beam  606  that is broadcast in the first designated lane  602 . The beam  606  can be transmitted by a wireless power transmitter to wirelessly transmit energy to one or more wireless power receivers. Specifically, the beam  606  can be transmitted by a wireless power transmitter to wirelessly transmit energy to one or more wireless power receivers as the wireless power receivers traverse the first designated lane  602 . More specifically the beam  606  can be transmitted to a position corresponding to a position of the one or more wireless power receivers in the first designated lane  602  as the wireless power receivers traverse the first designated lane  602 . 
     One or more wireless power transmitters can be controlled to sweep the beam  606  along the first designated lane  602 . Specifically, one or more wireless power transmitters can be controlled to sweep the beam  606  along the first designated lane  602  as a wireless power receiver moves with the beam  606  while traversing the first designated lane  602 . Alternatively, the one or more wireless power transmitters can be controlled to sweep the beam  606  along the first designated lane  602  based on a position of a wireless power receiver as it traverses the first designated lane  602 . For example, the one or more wireless power transmitters can be configured to broadcast the beam  606  to follow the wireless power receiver as the wireless power receiver traverses the first designated lane  602 . Further, a wireless power receiver traversing the first designated lane  602  can be configured to receive the beam  606  as it is swept across the first designated lane  602 , e.g. by following the beam  606  as it is swept across the first designated lane  602 . 
     While the beam  606  is shown to be contained entirely within the first designated lane  602 , in various embodiments, the beam  606  can extend to cover, at least part of, the second designated lane  604 . For example, the beam  606  can include one or more main lobes and/or grating lobes that extend into the second designated lane  604 . 
     Further, as the beam  606  can represent more than one beam, one or more transmitters can be configured to broadcast a plurality of beams of energy, represented as the beam  606  in  FIG. 6A , in the first designated lane  602 . The plurality of beams of energy can each include multiple lobes that are broadcast in the first designated lane  602 . Accordingly, one or more wireless power receivers can receive multiple beams of energy and/or multiple lobes as the wireless power receivers traverse the first designated lane  602 . In particular, multiple wireless power receivers can simultaneously receive energy from the multiple beams of energy and/or the multiple lobes as the wireless power receivers traverse the first designated lane  602  simultaneously. 
     The example beam pattern shown in  FIG. 6B  includes a beam  608  that is broadcast in the first designated lane  602  and the second designated lane  604 . Specifically, the beam  608  can be broadcast to switch between the first designated lane  602 , e.g. at position  610 , and the second designated lane  604 , e.g. at position  612 . For example, the beam  608  can be broadcast into the first designated lane  602 , e.g. at position  610 , switched off and then switched on as it is broadcast into the second designated lane  604 , e.g. at position  612 . Alternatively, the beam  608  can be swept between the first designated lane  602  and the second designated lane  604 , e.g. between positions  610  and  612 , without actually being turned off. 
     The beam  608  can be transmitted by one or more wireless power transmitters to wirelessly transmit energy to one or more wireless power receivers. Specifically, the beam  608  can be transmitted by one or more wireless power transmitters to wirelessly transmit energy to one or more wireless power receivers as the one or more wireless power receivers traverse the first designated lane  602  and/or the second designated lane  604 . More specifically the beam  608  can be transmitted to positions corresponding to one or more positions of one or more wireless power receivers in the first designated lane  602  and/or the second designated lane  604  as the one or more wireless power receivers traverse the first designated lane  602  and/or the second designated lane  604 . 
     One or more wireless power transmitters can be controlled to switch the beam  608  along the first designated lane  602  and the second designated lane  604 . Specifically, one or more wireless power transmitters can be controlled to switch the beam  608  along the first designated lane  602  and the second designated lane  604  as one or more wireless power receivers move with the beam  608  while traversing either or both the first designated lane  602  and the second designated lane  604 . Alternatively, the one or more wireless power transmitters can be controlled to switch the beam  608  along the first designated lane  602  and the second designated lane  604  based on a position of one or more wireless power receivers as they traverses either or both the first designated lane  602  and the second designated lane  604 . For example, the one or more wireless power transmitters can be configured to broadcast the beam  608  to follow the wireless power receiver as the wireless power receiver traverses either or both the first designated lane  602  and the second designated lane  604 . As follows, a wireless power receiver traversing either or both the first designated lane  602  and the second designated lane  604  can be configured to receive the beam  608  as it is switched between the first designated lane  602  and the second designated lane  604 . 
     In various embodiments, one or more wireless power transmitters can switch the beam  612  between the first designated lane  602  and the second designated lane  604  in response to a lane change request. For example, a transmitter can sweep the beam  612  from the first designated lane  602  to the second designated lane  604  in order to switch the beam  612  in response to a lane change request. Alternatively, a transmitter can turn off the beam  612  as it is broadcast in the first designated lane  602 , and reconfigure the beam  612  to be broadcast into the second designated lane  604  in response to a lane change request. A lane change request, as used herein, can indicate that one or more wireless power receivers are switching lanes, e.g. from the first designated lane  602  to the second designated lane. A lane change request can be received at one or more wireless power transmitters from a wireless power receiver. Further and as will be discussed in greater detail later, a lane change request can be received from a central control hub for a network of interlinked prescribed paths. 
     While the beam  608  is shown to be contained entirely within either the first designated lane  602  or the second designated lane  604 , in various embodiments, the beam  608  can extend to cover, at least part of, the second designated lane  604  or the first designated lane  602 . For example, the beam  608  can include one or more main lobes and/or grating lobes that extend into the second designated lane  604  while the beam is at position  610 . 
     Further, as the beam  608  can represent more than one beam, one or more transmitters can be configured to broadcast a plurality of beams of energy, represented as the beam  608  in  FIG. 6B , in the first designated lane  602  or the second designated lane  604 . The plurality of beams of energy can each include multiple lobes that are broadcast in the first designated lane  602  or the second designated lane  604 . Accordingly, one or more wireless power receivers can receive multiple beams of energy and/or multiple lobes as the wireless power receivers traverse the first designated lane  602  and/or the second designated lane  604 . In particular, multiple wireless power receivers can simultaneously receive energy from the multiple beams of energy and/or the multiple lobes as the wireless power receivers traverse the first designated lane  602  and/or the second designated lane  604  simultaneously. 
     The example beam pattern shown in  FIG. 6C  includes a first beam  614  that is broadcast in the first designated lane  602  and a second beam  616  that is broadcast in the second designated lane  604 . The first beam  614  can be broadcast in the first designated lane  602  simultaneously with broadcasting of the second beam  616  in the second designated lane  604 . Alternatively, the broadcasting of the first beam  614  in the first designated lane  602  and the second beam  616  in the second designated lane  604  can be switched to switch broadcasting of beams of energy in the first and second designated lanes  602  and  604 . More specifically, one or more transmitters can switch broadcasting of the first beam  614  and the second beam  616  in the corresponding first and second designated lanes  602  and  604  using time multiplexing of broadcasting. For example, the first beam  614  can be time multiplexed broadcast into the first designated lane  602  as the second beam  616  is not broadcasted according to timed multiplexed broadcasting to effectively switch broadcasting of the first beam  614  and the second beam  616 . In turn, this can cause switching of broadcasting of the first beam  614  and the second beam  616  between the first designated lane  602  and the second designated lane  604 . 
     The beam  614  and  616  can be transmitted by one or more wireless power transmitters to wirelessly transmit energy to one or more wireless power receivers. Specifically, the beams  614  and  616  can be transmitted by one or more wireless power transmitters to wirelessly transmit energy to one or more wireless power receivers as the one or more wireless power receivers traverse the first designated lane  602  and the second designated lane  604 . More specifically the beams  614  and  616  can be transmitted to positions corresponding to one or more positions of one or more wireless power receivers in the first designated lane  602  and the second designated lane  604  as the one or more wireless power receivers traverse the first designated lane  602  and the second designated lane  604 . 
     One or more wireless power transmitters can be controlled to switch the beams  614  and  616  along the first designated lane  602  and the second designated lane  604 . Specifically, one or more wireless power transmitters can be controlled to switch the beams  614  and  616  along the first designated lane  602  and the second designated lane  604  as one or more wireless power receivers move with the beams  614  and  616  while traversing either or both the first designated lane  602  and the second designated lane  604 . Alternatively, the one or more wireless power transmitters can be controlled to switch the beams  614  and  616  along the first designated lane  602  and the second designated lane  604  based on a position of one or more wireless power receivers as they traverse either or both the first designated lane  602  and the second designated lane  604 . For example the one or more wireless power transmitters can be configured to broadcast the beams  614  and  616  to sweep or otherwise follow one or more wireless power receivers as the wireless power receivers traverse either or both the first designated lane  602  and the second designated lane  604 . As follows, wireless power receivers traversing either or both the first designated lane  602  and the second designated lane  604  can be configured to receive the beams  614  and  616  as they traverse the first designated lane  602  and the second designated lane  604 . 
     In various embodiments, one or more wireless power transmitters can switch the beams  614  and  616  between the first designated lane  602  and the second designated lane  604  in response to a lane change request. For example, one or more transmitters can time multiplex broadcasting of the beams  614  and  616  in the first designated lane  602  and the second designated lane  604  in response to a lane change request. This effectively switches broadcasting of the beams  614  and  616  in the first designated lane  602  and the second designated lane  604  in response to a lane change request. 
     While the beams  614  and  616  are shown to be contained entirely within either the first designated lane  602  or the second designated lane  604 , in various embodiments, the beams  614  and  616  can extend to cover, at least part of, the second designated lane  604  or the first designated lane  602 . For example, the first beam  614  can include one or more main lobes and/or grating lobes that extend into the second designated lane  604 . 
     Further, as the beams  614  and  616  can each represent more than one beam, one or more transmitters can be configured to broadcast a plurality of beams of energy, represented as the beams  614  and  616  in  FIG. 6C , in the first designated lane  602  and/or the second designated lane  604 . The plurality of beams of energy can each include multiple lobes that are broadcast in the first designated lane  602  and/or the second designated lane  604 . Accordingly, one or more wireless power receivers can receive multiple beams of energy and/or multiple lobes as the wireless power receivers traverse the first designated lane  602  and/or the second designated lane  604 . As follows, multiple wireless power receivers can simultaneously receive energy from the multiple beams of energy and/or the multiple lobes as the wireless power receivers traverse the first designated lane  602  and/or the second designated lane  604  simultaneously. 
     Referring back to the example system  100 , shown in  FIG. 1 , the wireless power transmitter  102  can broadcast one or more beams of energy to the wireless power receiver  104  according to the example beam patterns shown in  FIGS. 5A-F  and  FIGS. 6A-C . Further, the wireless power receiver  104  can receive energy wirelessly through one or more beams of energy broadcast according to the example beam patterns shown in  FIGS. 5A-F  and  FIGS. 6A-C . 
     As discussed previously, the wireless power transmitter  102  can transmit beams of energy to the wireless power receiver  104  based on a position of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . Specifically, the wireless power transmitter  102  can transmit beams of energy to the wireless power receiver  104  based on an actively tracked position of the wireless power receiver  104  as the wireless power receiver  104  traverses the network of interlinked prescribed paths  106 . Similarly, the wireless power receiver  104  can receive one or more beams of energy from the wireless power transmitter  102  based on a position of the wireless power receiver  104  in the network of interlinked prescribed paths  106 . Specifically, the wireless power receiver  104  can receive one or more beams of energy from the wireless power transmitter  102  based on an actively tracked position of the wireless power receiver  104  as the wireless power receiver  104  traverses the network of interlinked prescribed paths  106 . 
     The wireless power transmitter  102  can actively track a position of the wireless power receiver  104  as the wireless power receiver traverses the network of interlinked prescribed paths  106 . Specifically, the wireless power transmitter  102  can actively track a position of the wireless power receiver  104  by communicating with the wireless power receiver  104 , e.g. as the wireless power receiver  104  traverses the network of interlinked prescribed paths  106 . 
     The wireless power transmitter  102  can communicate with the wireless power receiver  104  over an auxiliary communication channel, e.g. for actively tracking a position of the wireless power receiver  104 . An auxiliary communication channel can include an applicable communication channel separate from one or more beams of energy broadcast by the wireless power transmitter  102  and potentially received at the wireless power receiver  104 , e.g. for purposes of wirelessly transferring power. Specifically, an auxiliary communication channel can include an applicable short range wireless communication channel. For example, an auxiliary communication channel can include a WiFi® communication channel, Zigbee® communication channel, Bluetooth® communication channel, or an applicable cellular communication channel. Further, an auxiliary communication channel can include an acoustic communication channel. 
     In using an auxiliary communication channel with the wireless power receiver  104  to actively track a position of the wireless power receiver  104 , the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using coordinate data. Specifically, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using coordinate data of the wireless power receiver  104  that is received from the wireless power receiver  104  over an auxiliary communication channel. More specifically, the wireless power receiver  104  can generate coordinate data and transmit the coordinate data to the wireless power receiver  104  over an auxiliary communication channel. In turn, the wireless power transmitter  102  can actively track a position of the wireless power receiver  104  using the coordinate data. Coordinate data includes applicable data describing a position of the wireless power receiver  104  in space and/or the network of interlinked prescribed paths. Specifically, coordinate data can include global position system (herein referred to as “GPS”) data indicating a position of the wireless power receiver  104 . For example, the wireless power receiver  104  can include a GPS module for generating GPS coordinate data that the wireless power receiver  104  can then send to the wireless power transmitter  102  through an auxiliary communication channel. 
     Further, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using reflected light from the wireless power receiver  104 . Specifically, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using light detection and ranging (herein referred to as “LIDAR”). For example, the wireless power transmitter  102  can broadcast light to the wireless power receiver  104  and subsequently identify a position of the wireless power receiver  104  based on the light that is reflected back from the wireless power receiver  104 . 
     Additionally, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using reflected radio waves from the wireless power receiver  104 . Specifically, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using Radar. For example, the wireless power transmitter  102  can broadcast radio waves to the wireless power receiver  104  and subsequently identify a position of the wireless power receiver  104  based on the radio waves that are reflected back from the wireless power receiver  104 . 
     Also, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using reflected acoustic waves from the wireless power receiver  104 . Specifically, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using Sonar. For example, the wireless power transmitter  102  can broadcast acoustic waves to the wireless power receiver  104  and subsequently identify a position of the wireless power receiver  104  based on the acoustic waves that are reflected back from the wireless power receiver  104 . 
     Further, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using an optical camera. Specifically, the wireless power transmitter  102  can use an optical camera to estimate a distance between the wireless power receiver  104  and the wireless power transmitter  102 , corresponding to a position of the wireless power receiver  104 . Additionally, the wireless power transmitter  102  can actively track the position of the wireless power receiver  104  using structured light. Specifically, the wireless power transmitter  102  can project structured light having a known pattern, e.g. broadcast pattern, towards the wireless power receiver  104 . Subsequently, an optical camera can detect changes in the pattern of the structured light caused by the wireless power receiver  104 . In turn, these changes in the pattern of the structured light can be measured, e.g. based on the known pattern of the structure light, to determine a position of the wireless power receiver  104 . 
     The wireless power transmitter  102  can actively track the position of the wireless power receiver  104  through an implied determination of the position of the wireless power receiver  104 . An implied determination of the position of the wireless power receiver  104  can include an estimated position of the wireless power receiver  104 . More specifically, the estimated position of the wireless power receiver  104  can include an actual position of the wireless power receiver, not an actual position of the wireless power receiver, or a position that is adjacent to an actual position of the wireless power receiver. An estimated position of the wireless power receiver  104  can be determined using one or a combination of the previously described techniques for tracking a position of the wireless power receiver  104 . 
     The wireless power transmitter  102  can use an implied determination of the position of the wireless power receiver  104  to determine an actual position of the wireless power receiver  104  using a beam of energy broadcast by the wireless power transmitter  102 . Specifically, the wireless power transmitter  102  can broadcast a beam of energy, e.g. for wirelessly transferring power, to an estimated position of the wireless power receiver. Subsequently, based on backscattered energy, or a lack thereof, of the beam energy broadcasted to the estimated position, the wireless power transmitter  102  can determine an actual position of the wireless power receiver  104 . For example, if the wireless power transmitter  102  does not receive any backscattered energy from the beam of energy, then the wireless power transmitter  102  can determine that the wireless power receiver  104  is not at the estimated location. In another example, if the wireless power transmitter  102  receives backscattered energy from the beam of energy at a specific angle, then the wireless power transmitter  102  can determine the actual position of the wireless power receiver based on the angle at which the backscattered energy is received. 
     In using an implied determination of the position of the wireless power receiver  104  to determine an actual position of the wireless power receiver  104 , the wireless power transmitter  102  can construct a beam that is broadcast to an estimated position of the wireless power receiver  104  based on energy received from the wireless power receiver  104 . Specifically, the wireless power transmitter  102  can receive a pilot beam that is broadcast from the wireless power receiver. The wireless power transmitter  102  can then use the pilot beam to broadcast a beam of energy towards the wireless power receiver  104 , e.g. to an estimated position of the receiver  104 , in order to determine an actual position of the wireless power receiver  104 . Specifically, the wireless power transmitter  102  can construct a beam of energy by time-reversing the pilot beam with power to form the beam of energy that points at the estimated position of the wireless power receiver  104 . 
     In transmitting one or more beams of energy based on a position of the wireless power receiver  104 , the wireless power transmitter  102  can broadcast the one or more beams of energy based on a received lane change request. Specifically, a lane change request can indicate the wireless power receiver  104  is switching designated lanes in the network of interlinked prescribed paths  106 . Subsequently, the wireless power receiver  104  can broadcast the one or more beams of energy to continue to wirelessly transfer energy to the wireless power receiver  104  as it switches the designated lanes. The wireless power transmitter  102  can receive the lane change request from the wireless power receiver  104 , e.g. through an auxiliary communication channel. Alternatively and as will be discussed in greater detail later, the wireless power transmitter  102  can received the lane change request from a central control hub for the network of interlinked prescribed paths  106 . 
       FIG. 7  illustrates another example system  700  for transmitting and receiving energy wirelessly. The example system  700  includes a first wireless power transmitter  702  and a second wireless power transmitter  704 . Additionally, the example system  700  includes a wireless power receiver  706  traversing a network of interlinked prescribed paths  708 . The first wireless power transmitter  702  and the second wireless power transmitter  704  can function according to the wireless power transmitters described herein in transmitting energy wirelessly to the wireless power receiver  706 . Specifically, the first wireless power transmitter  702  and the second wireless power transmitter  704  can wirelessly transmit energy to the wireless power receiver  706  as the wireless power receiver  706  traverses the network of interlinked prescribed paths  708 . Further, the wireless power receiver  706  can function according to the wireless power receivers described herein in receiving energy wirelessly from the first wireless power transmitter  702  and the second wireless power transmitter  704 . Specifically, the wireless power receiver  706  can wirelessly receive energy from the first wireless power transmitter  702  and the second wireless power transmitter  704  as the wireless power receiver  706  traverses the network of interlinked prescribed paths  708 . 
     Either or both the first wireless power transmitter  702  and the second wireless power transmitter  704  can be operatively coupled to the wireless power receiver  706  through a handoff, e.g. between two or more wireless power transmitters. Specifically, the second wireless power transmitter  704  can be operatively coupled to the wireless power receiver  706  through a handoff with the first wireless power transmitter  702 . In being operatively coupled to the wireless power receiver  706  through a handoff, either or both the first wireless power transmitter  702  and the second wireless power transmitter  704  can wirelessly transfer energy to the wireless power receiver  706  as part of the handoff. For example, the first wireless power transmitter  702  and the second wireless power transmitter  704  can engage in a handoff. Further in the example, either during or after the handoff, the first wireless power transmitter  702  can stop transmitting wireless energy to the wireless power receiver  706 , e.g. by stopping broadcasting of a beam of energy to the wireless power receiver  706 .

Accordingly, a handoff can occur in coordination with the wireless power receiver  706  switching from the first prescribed path to the second prescribed path in the network of interlinked prescribed paths  708 . Specifically, the first wireless power transmitter  702  and the second wireless power transmitter  704  can engage in the handoff so that the first wireless power transmitter  702  stops transmitting wireless energy to the wireless power receiver  706  and the second wireless power transmitter  704  begins transmitting wireless energy to the wireless power receiver  706  as the wireless power receiver  706  leaves the first prescribed path and enters the second prescribed path. 
     Further, the first wireless power transmitter  702  can correspond to a first designated lane in the network of interlinked prescribed paths  708 . Specifically, the first wireless power transmitter  702  can be configured to wirelessly transfer energy to one or more wireless power transmitters traversing the first designated lane of the network of interlinked prescribed paths  708 .

Specifically, the first wireless power transmitter  702  and the second wireless power transmitter  704  can engage in the handoff so that the first wireless power transmitter  702  stops transmitting wireless energy to the wireless power receiver  706  and the second wireless power transmitter  704  begins transmitting wireless energy to the wireless power receiver  706  as the wireless power receiver  706  leaves the first designated lane and enters the second designated lane. 
     A handoff between the first wireless power transmitter  702  and the second wireless power transmitter  704  can be coordinated by the first wireless power transmitter  702 . In coordinating the handoff between the first wireless power transmitter  702  and the second wireless power transmitter  704 , the first wireless power transmitter  702  can communicate with the second wireless power transmitter  704  as part of coordinating and conducting the handoff. Specifically, the first wireless power transmitter  702  can conduct one or more handshakes with the second wireless power transmitter  704  as part of communicating with the second wireless power transmitter  704  as part of the handoff. Further, in coordinating the handoff, the first wireless power transmitter  702  can communicate with the wireless power receiver  706 . For example, the first wireless power transmitter  702  can send an acknowledgement to the wireless power receiver  706  indicating that the wireless power receiver  706  will begin receiving energy wirelessly from the second wireless power transmitter  704 . 
     Further, a handoff between the first wireless power transmitter  702  and the second wireless power transmitter  704  can be coordinated by the second wireless power transmitter  704 . In coordinating the handoff between the first wireless power transmitter  702  and the second wireless power transmitter  704 , the second wireless power transmitter  704  can communicate with the first wireless power transmitter  702  as part of coordinating and conducting the handoff.

       FIG. 8  illustrates an example system  800  for transmitting and receiving energy wirelessly that is managed through a central control hub  802 . The example system  800  includes a wireless power transmitter  804 . Additionally, the example system  800  includes a wireless power receiver  806  traversing a network of interlinked prescribed paths  808 . The wireless power transmitter  804  functions according to the wireless power transmitters described herein in transmitting energy wirelessly to the wireless power receiver  806 . Specifically, the wireless power transmitter  802  can wirelessly transmit energy to the wireless power receiver  806  as the wireless power receiver  806  traverses the network of interlinked prescribed paths  808 . Further, the wireless power receiver  806  functions according to the wireless power receivers described herein in receiving energy wirelessly from the wireless power transmitter  804 . Specifically, the wireless power receiver  806  can wirelessly receive energy from the wireless power transmitter  804  as the wireless power receiver  806  traverses the network of interlinked prescribed paths  808 . 
     The central control hub  802  functions to control, at least in part, wireless transmission of energy to the wireless power receiver  806  through the wireless power transmitter  804 . While the example system  800  shown in  FIG. 8  includes only a single wireless power transmitter  804 , in various embodiments, the system  800  can include a plurality of wireless power transmitters. Specifically, the system  800  can include a plurality of wireless power transmitters that are configured to wirelessly transmit energy to one or more wireless power receivers as the wireless power receivers traverse the network of interlinked prescribed paths  808 . More specifically, the central control hub  802  can control the plurality of wireless power transmitters to wirelessly transmit energy to one or more wireless power receivers as they traverse the network of interlinked prescribed paths  808 . 
     In controlling the wireless power transmitter  804  to wirelessly transmit energy, the central control hub  802  can control the wireless power transmitter  804  to broadcast one or more beams of energy to the network of interlinked prescribed paths  808 .

In using a plurality of wireless power transmitters to track a position of a wireless power receiver  806 , the central control hub  802  can track positions of a plurality of wireless power receivers traversing the network of interlinked prescribed paths  808  at a given time. In turn, the central control hub  802  can use the tracked positions to control wireless power transmitters of the network of interlinked prescribed paths  808  to transmit beams of energy to the plurality of wireless power receivers in the network of interlinked prescribed paths  808 , e.g. as the receivers traverse the network of interlinked prescribed paths  808 . 
     The wireless power transmitter  804  can actively track a position of the wireless power receiver  806  through the central control hub  802 . Specifically, the central control hub  802  can track a position of the wireless power receiver  806  and generate position data indicating the tracked position of the wireless power receiver  806 . Subsequently, the central control hub  802  can provide the position data to the wireless power transmitter  804 , which can then use the position data to actively track the position of the wireless power receiver  806 . For example, the central control hub  802  can GPS coordinates from the wireless power receiver  806  through an auxiliary communication channel and generate position data based on the GPS coordinates. The central control hub  802  can then provide the position data to the wireless power transmitter  804  which can then actively track the position of the wireless power receiver  806  using the position data received from the central control hub  802 . 
     In controlling the wireless power transmitter  804 , the central control hub  802  can generate and/or send lane change requests to the wireless power transmitter  804 . For example, the central control hub  802  can receive a lane change request from the wireless power receiver  806 . The central control hub  802  can then forward the lane change request to the wireless power transmitter  804 . Subsequently, the wireless power transmitter  804  can control transmission of one or more beams of energy based on the lane change request received from the central control hub  802 . 
     Further, in controlling wireless power transmitters, the central control hub  802  can coordinate handoffs between the wireless power transmitters, e.g. including the wireless power transmitter  804 . Specifically, the central control hub  802  can instruct one or more wireless power transmitters to perform a handoff as the wireless power receiver  806  traverses the network of interlinked prescribed paths  808 . For example, the central control hub  802  can instruct one or more wireless power transmitters to perform one or more handshakes as part of a handoff for transmitting energy wirelessly to the wireless power receiver  806 . Further, the central control hub  802  can communicate with the wireless power receiver  806  for purposes of coordinating a handoff between wireless power transmitters. For example, the central control hub  802  can receive, from the wireless power receiver  806 , an indication that the wireless power receiver  806  is switching prescribed paths. Subsequently, the central control hub  802  can coordinate a handoff between two wireless power transmitters in response to the wireless power receiver switching the prescribed paths.

The pre-determined path  904  can be pre-determined based on traffic of wireless power receivers in the network of interlinked prescribed paths  900 . For example, the pre-determined path  904  can be a route through the network of interlinked prescribed paths  900  that is pre-determined to be the fastest route through the network of interlinked prescribed paths  900 . 
     In the example network  900  shown in  FIG. 9 , the wireless power receiver  902  can switch from traversing the network  900  according to the pre-determined path  904  and continue traversing the network  900  according to the modified path  906 .
