Title: Recovering wind power from remote vehicles

Description:
BACKGROUND 
     The present invention relates generally to the field of remote vehicles, and more particularly to energy recovery landing zones for remote vehicles. 
     Wind power or alternatively wind energy is the use of wind to provide mechanical power through wind turbines which turn electric generators for electrical power. Wind energy refers to the kinetic energy of air in motion, also called wind. A wind turbine is a device which transforms the wind&#39;s kinetic energy into electrical energy. Wind turbines are manufactured in a wide variety of sizes, with either horizontal or vertical axes. 
     A fluid flowing around the surface of an object exerts a force upon it. Lift is the component of this force that is applied perpendicular to the oncoming flow direction. It is in contrast with the drag force, which is the component of the force parallel to the flow direction. Lift frequently acts in an upward direction to counter the force of gravity, but can act in any direction at right (perpendicular) angles to the direction of the flow. If the surrounding fluid is air, the force is referred to as aerodynamic force. 
     SUMMARY 
     According to an aspect of the present invention, there is a method, computer program product and/or system for use with a remote vehicle landing zone having a landing surface including a plurality of independently moveable landing surface modules capable of three dimensional movement, where each independently moveable landing surface module further includes a wind power generation module that performs the following operations (not necessarily in the following order): (i) determining an air turbulence dataset corresponding to wind force(s) of air turbulence resulting from operation of a remote vehicle in the vicinity of the landing zone applied to at least some of the plurality of independently moveable landing surface modules; (ii) determining whether the wind force(s) are above a threshold value; (iii) responsive to determining that the wind force(s) are above a threshold value, determining a subset of the plurality of independently moveable landing surface modules based, at least in part, on the air turbulence dataset; and (iv) for at least some of the subset of the plurality of independently moveable landing surface modules, exposing their corresponding wind power generation module to generate electrical power based on the wind force(s) of the air turbulence resulting from operation of a remote vehicle in the vicinity of the landing zone.

     DETAILED DESCRIPTION 
     Some embodiments of the present invention are directed to techniques for recovering power from remote vehicles near a landing surface. Air turbulence from a remote vehicle near a landing surface is detected and measured. When the air turbulence exceeds a threshold, a subset of landing surface components corresponding to sections of the landing surface with attached wind power generators are determined for wind power generation from the detected air turbulence. The wind power generators of the subset of landing surface components are exposed from their protective coverings, and the subset of landing surface components are reoriented towards the source of the air turbulence, tracking the remote vehicle generating the air turbulence. Power generated by the wind power generators can be stored and used to recharge remote vehicles that land at the landing surface. 
     This Detailed Description section is divided into the following subsections: (i) The Hardware and Software Environment; (ii) Example Embodiment; (iii) Further Comments and/or Embodiments; and (iv) Definitions. 
     I. The Hardware and Software Environment 
     The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention. 
     The computer readable storage medium sometimes referred to as a machine readable storage device, can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (for example, light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire. 
     A “storage device” is hereby defined to be any thing made or adapted to store computer code in a manner so that the computer code can be accessed by a computer processor. A storage device typically includes a storage medium, which is the material in, or on, which the data of the computer code is stored. A single “storage device” may have: (i) multiple discrete portions that are spaced apart, or distributed (for example, a set of six solid state storage devices respectively located in six laptop computers that collectively store a single computer program); and/or (ii) may use multiple storage media (for example, a set of computer code that is partially stored in as magnetic domains in a computer&#39;s non-volatile storage and partially stored in a set of semiconductor switches in the computer&#39;s volatile memory). The term “storage medium” should be construed to cover situations where multiple different types of storage media are used. 
     Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. 
     Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention. 
     Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions. 
     These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks. 
     The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions. 
     As shown in  FIG.  1 A , networked computers system  100  is an embodiment of a hardware and software environment for use with various embodiments of the present invention. Networked computers system  100  includes: server subsystem  102  (sometimes herein referred to, more simply, as subsystem  102 ); remote vehicle  104 ; communication network  114 ; and landing surface  116 . Server subsystem  102  includes: server computer  200 ; communication unit  202 ; processor set  204 ; input/output (I/O) interface set  206 ; memory  208 ; persistent storage  210 ; display  212 ; external device(s)  214 ; random access memory (RAM)  230 ; cache  232 ; and program  300 . 
     Subsystem  102  may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any other type of computer (see definition of “computer” in Definitions section, below). Program  300  is a collection of machine readable instructions and/or data that is used to create, manage and control certain software functions that will be discussed in detail, below, in the Example Embodiment subsection of this Detailed Description section. 
     Subsystem  102  is capable of communicating with other computer subsystems via communication network  114 . Network  114  can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and can include wired, wireless, or fiber optic connections. In general, network  114  can be any combination of connections and protocols that will support communications between server and client subsystems. 
     Subsystem  102  is shown as a block diagram with many double arrows. These double arrows (no separate reference numerals) represent a communications fabric, which provides communications between various components of subsystem  102 . This communications fabric can be implemented with any architecture designed for passing data and/or control information between processors (such as microprocessors, communications and network processors, etc.), system memory, peripheral devices, and any other hardware components within a computer system. For example, the communications fabric can be implemented, at least in part, with one or more buses. 
     Memory  208  and persistent storage  210  are computer-readable storage media. In general, memory  208  can include any suitable volatile or non-volatile computer-readable storage media. It is further noted that, now and/or in the near future: (i) external device(s)  214  may be able to supply, some or all, memory for subsystem  102 ; and/or (ii) devices external to subsystem  102  may be able to provide memory for subsystem  102 . Both memory  208  and persistent storage  210 : (i) store data in a manner that is less transient than a signal in transit; and (ii) store data on a tangible medium (such as magnetic or optical domains). In this embodiment, memory  208  is volatile storage, while persistent storage  210  provides nonvolatile storage. The media used by persistent storage  210  may also be removable. For example, a removable hard drive may be used for persistent storage  210 . Other examples include optical and magnetic disks, thumb drives, and smart cards that are inserted into a drive for transfer onto another computer-readable storage medium that is also part of persistent storage  210 . 
     Communications unit  202  provides for communications with other data processing systems or devices external to subsystem  102 . In these examples, communications unit  202  includes one or more network interface cards. Communications unit  202  may provide communications through the use of either or both physical and wireless communications links. Any software modules discussed herein may be downloaded to a persistent storage device (such as persistent storage  210 ) through a communications unit (such as communications unit  202 ). 
     I/O interface set  206  allows for input and output of data with other devices that may be connected locally in data communication with server computer  200 . For example, I/O interface set  206  provides a connection to external device(s)  214 . External device(s)  214  will typically include devices such as a keyboard, keypad, a touch screen, and/or some other suitable input device. External device(s)  214  can also include portable computer-readable storage media such as, for example, thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, for example, program  300 , can be stored on such portable computer-readable storage media. I/O interface set  206  also connects in data communication with display  212 . Display  212  is a display device that provides a mechanism to display data to a user and may be, for example, a computer monitor or a smart phone display screen. 
     Remote vehicles, as understood in the context of this document, are understood to be a type of aircraft vehicle without any pilot, crew, or passengers on board. Some remote vehicles include vertical takeoff and landing (VTOL) capabilities featuring a plurality of powered rotors, such as a quadcopter type of vehicle with four rotors. Remote vehicles operate with varying degrees of direct human intervention, from direct human piloting where a human provides input to control the remote vehicle, autopilot assisted operations, and full autonomy without direct human intervention. In this simplified embodiment, remote vehicle  104  is a fully autonomous quadcopter type of remote vehicle with VTOL capabilities that can hover, take off and land vertically. 
     In this embodiment, program  300  is stored in persistent storage  210  for access and/or execution by one or more computer processors of processor set  204 , usually through one or more memories of memory  208 . It will be understood by those of skill in the art that program  300  may be stored in a more highly distributed manner during its run time and/or when it is not running. Program  300  may include both machine readable and performable instructions and/or substantive data (that is, the type of data stored in a database). In this particular embodiment, persistent storage  210  includes a magnetic hard disk drive. To name some possible variations, persistent storage  210  may include a solid state hard drive, a semiconductor storage device, read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, or any other computer-readable storage media that is capable of storing program instructions or digital information.

     The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed.

     II. Example Embodiment 
     As shown in  FIG.  1 A , networked computers system  100  is an environment in which an example method according to the present invention can be performed. As shown in  FIG.  2   , flowchart  250  shows an example method according to the present invention. As shown in  FIG.  3   , program  300  performs or control performance of at least some of the method operations of flowchart  250 . This method and associated software will now be discussed, over the course of the following paragraphs, with extensive reference to the blocks of  FIGS.  1 A,  1 B,  2  and  3   . 
     Processing begins at operation  5255 , where air turbulence dataset determination module (“mod”)  302  determines an air turbulence dataset corresponding to air turbulence from a remote vehicle. In this simplified embodiment, the air turbulence dataset is determined from wind force datasets measured by landing surface  116  of  FIG.  1 A , originating from rotors (not shown) of remote vehicle  104  as it approaches landing surface  116  for a landing. More specifically, landing surface  116 , shown in greater detail in  FIG.  1 B , includes four landing surface components ( 118 ,  128 ,  138  and  148 ), which each respectively include wind detectors ( 120 ,  130 ,  140  and  150 ) used to measure wind force datasets comprising wind direction and wind speed readings. Each wind detector will contribute a separate wind force dataset to the air turbulence dataset independent of the other wind detectors. In this simplified embodiment, wind detector  120  measures a wind force dataset corresponding to a 15 mile per hour (mph) wind speed originating from directly above landing surface component  118 , wind detector  130  measures a wind force dataset corresponding to a 12 mph wind speed originating from above and to the West of landing surface component  128 , wind detector  140  measures a wind force dataset corresponding to a 12 mph wind speed originating from above and to the East of landing surface component  138 , and wind detector  150  measures a wind force dataset corresponding to a 9 mph wind speed originating from above and to the north of landing surface component  148 . While in this simplified embodiment, landing surface  116  includes four landing surface components, the four landing surface components are an illustrative example of a landing surface that may include many landing surface components, configured to generate power from nearby air turbulences that originate from remote vehicles within the proximate environment. The landing surface components may be configured in a variety of patterns within the landing surface, including, for example, a grid pattern of square shaped landing surface components, or a honeycomb of hexagonal shaped landing surface components. 
     Processing proceeds to operation S 260 , where wind force(s) threshold exceeding determination mod  304  determines that wind force(s) in the air turbulence dataset exceed a threshold. In this simplified embodiment, wind force(s) are determined to exceed the threshold when a wind force dataset of the air turbulence dataset has a corresponding wind speed exceeding a predetermined wind speed threshold, which is 10 mph. In this simplified embodiment, the wind force datasets corresponding to wind detectors  120 ,  130  and  140  all include wind speeds exceeding 10 mph, resulting in wind force(s) threshold exceeding determination mod  304  determining that wind forces in the air turbulence dataset exceed the 10 mph wind speed threshold. This determination indicates that wind detectors  120 ,  130 , and  140  each measured a wind force dataset with a wind speed over the predetermined wind speed threshold of 10 mph, and that wind detector  150  did not measure a wind force dataset with a wind speed over 10 mph. In some alternative embodiments, the threshold is determined by a machine learning model trained using historical datasets of remote vehicles taking off and landing at the landing surface, including how much lift force is required for each remote vehicle to safely take off and land at the landing surface and how much each remote vehicle weighed (including any cargo), outputting a threshold value for minimum lift force required when supplied with a remote vehicle weight (with weight of cargo included, if applicable). 
     Processing proceeds to operation S 265 , where landing surface components subset determination mod  306  determines a subset of landing surface components for wind power generation. In this simplified embodiment, landing surface components subset determination mod  306  determines a subset of landing surface components for wind power generation based on which landing surface components correspond to wind detectors that measured the wind force dataset (or datasets) with a corresponding wind speed that exceeds the predetermined threshold. As determined at S 260 , wind detectors  120 ,  130 , and  140  are determined to have each measured a wind force dataset with a wind speed over the predetermined wind speed threshold of 10 mph. With wind detector  120  corresponding to landing surface component  118 , wind detector  130  corresponding to landing surface component  128 , and wind detector  140  corresponding to landing surface component  138 , landing surface components subset determination mod  306  determines landing surface component  118 , landing surface component  128  and landing surface component 138  for inclusion in the subset of landing surface components for wind power generation. 
     Processing proceeds to operation S 270 , where wind power generation module exposing mod  308  exposes wind power generation modules for the subset of landing surface components. In this simplified embodiment, wind power generation module exposing mod  308  exposes wind power generation modules for the subset of landing surface components by instructing each of the landing surface components included in the subset of landing surface components for wind power generation to open their respective shutters, allowing wind to flow into their respective wind power generators, which are wind turbines embedded within their respective landing surface components. These wind power generators, when exposed from their shutters, generate electrical power through conversion of wind that passes through them (and their respective landing surface components). 
     The subset of landing surface components for wind power generation includes landing surface component  118 , landing surface component  128  and landing surface component  138 , while excluding landing surface component  148 . Wind power generation module exposing mod  308  instructs landing surface component  118  to expose wind power generator  126  for wind power generation by opening shutter  124 . Landing surface  128  is also instructed by wind power generation module exposing mod  308  to expose wind power generator  136  for wind power generation by opening shutter  134 . Lastly, wind power generation module exposing mod  308  instructs landing surface component  138  to expose wind power generator  146  for wind power generation by opening shutter  144 . Wind power generator  156  remains closed off from wind power generation by shutter  154  because landing surface component  148  is not included in the subset of landing surface components for wind power generation. In some alternative embodiments, the wind power generators are protected by other types of shielding, such as a retractable cover. In further alternative embodiments, the wind power generators are permanently exposed. 
     Processing proceeds to operation S 275 , where landing surface components repositioning mod  310  repositions at least some of the subset of landing surface components based on the direction of the wind force(s). In this simplified embodiment, landing surface components repositioning mod  310  repositions at least some of the subset of landing surface components based on the direction of the wind force(s) in the wind force(s) dataset. For each landing surface component in the subset of landing surface components, landing surface components repositioning mod  310  first determines which direction to reposition the landing surface component to face. To determine which direction, the wind direction reading of the wind force(s) dataset corresponding to the landing surface component is used to optimize efficiency of power generation by the wind power generator of the landing surface component from the wind originating from remote vehicle  104 . For a wind turbine, such as the wind power generators in the landing surface components, it is efficient for wind power generation to have the wind turbine facing into the wind (or perpendicular to the direction of the wind), and are considered misaligned when facing other directions. For sources of wind originating from a point, such as air turbulence from a remote vehicle near several wind power generators, each wind power generator may have different directions where wind power generation is most efficient. Orienting the landing surface components, and their respective wind power generators, may enhance the amount of power generated from the air turbulence resulting from remote vehicle  104 . 
     As previously established in this simplified embodiment, the subset of landing surface components includes landing surface component  118 , landing surface component  128 , and landing surface component  138 , and excludes landing surface component  148 . For landing surface component  118 , the wind direction previously determined at  5255  indicated that the wind detected by wind detector  120  is originating from directly above landing surface component  118 , resulting in no change in direction for landing surface component  118  as the wind direction is already directly perpendicular to the surface of landing surface component  118 . For landing surface component  128 , the wind direction previously determined at S 255  indicated that the wind detected by wind detector  130  is originating from above and to the West of landing surface component  128 , resulting in the direction for landing surface component  128  changing to be tilted towards above and to the West of landing surface component  128  to reach a perpendicular orientation to the wind direction determined through wind detector  130 . For landing surface component  138 , the wind direction previously determined at S 255  indicated that the wind detected by wind detector  140  is originating from above and to the East of landing surface component  138 , resulting in the direction for landing surface component  138  changing to be tilted towards above and to the East of landing surface component  138  to reach a perpendicular orientation to the wind direction determined through wind detector  140 . No such determination is made for landing surface component  148 , which was excluded from the subset of landing surface components. 
     Next, landing surface components repositioning mod  310  instructs the movement modules of the landing surface components that have new directions to face determined by landing surface components repositioning mod  310 . In this simplified embodiment, movement modules  122 ,  132 ,  142  and  152  are hydraulic mechanisms that can alter the orientation of their respective landing surface components. As landing surface component  128  and landing surface component  138  are the only landing surface components that have new directions determined by landing surface components repositioning mod  310 , landing surface components repositioning mod  310  instructs their respective movement modules to reorient each of them to their new directions. Landing surface components repositioning mod  310  instructs movement module  132  to reposition landing surface component  128  to face up and to the West, and movement module  142  to reposition landing surface component  138  to face up and to the East. In some alternative embodiments, the movement modules are electrical motors connected to gears that tilt and elevate the landing surface components to achieve desired orientations. 
     Processing proceeds to operation S 280 , where power transmission mod  312  transmits power generated by wind power generation modules to power storage. In this simplified embodiment, air turbulence originating from remote vehicle  104  generates wind that flows through wind power generator  126  of landing surface component  118 , wind power generator  136  of landing surface component  128 , and wind power generator  146  of landing surface component  138  to generate electrical power, which power transmission mod  312  instructs the respective landing surface components to transmit said power to the connected power storage unit, power storage  158 . In this simplified embodiment, power storage  158  is a battery that converts electrical energy into chemical potential energy. 
     In some alternative embodiments, power stored in power storage connected to the landing surface (such as power storage  158 ) is retransmitted to one or more remote vehicles at the landing surface through traditional power transmission couplings or through wireless power transmission techniques, to recharge the remote vehicles for subsequent use. In some other alternative embodiments, the power stored in power storage connected to the landing surface can be retransmitted to one or more wind power generator modules to power the wind power generator modules to generate air turbulence and wind to assist in reducing the rate of descent for a remote vehicle that has insufficient maneuvering capabilities to avoid damage during landing. Wind generated by the one or more wind power generator modules may reduce or limit the damage received by the remote vehicle during said landing.

       FIGS.  4  and  5   , discussed in greater detail below, illustrate how the wind power generation modules generate power based on the air turbulence created by remote vehicle during landings and takeoffs, and how the landing or taking off surface can be deformed to generate power from different sides of the remote vehicle. 
     Diagram  400  of  FIG.  4    shows a remote vehicle landing ecosystem including: remote vehicle  402 ; landing surface  404 ; wind power generation modules  406 ; and air turbulence  408 . Shutters in landing surface  404  are closed to protect wind power generation modules  406  but can be opened in response to detected (or predicted) air turbulence from remote vehicles such as remote vehicle  402 . 
     Diagram  500  of  FIG.  5    shows the remote vehicle landing ecosystem of  FIG.  4    during deformation to maximize wind power generation, including: remote vehicle  502 ; landing surface  504 ; and wind power generation modules  506 ; air turbulence  508 . Responsive to detecting (or predicting) the presence of air turbulence from a remote vehicle landing, such as remote vehicle  502 , or taking off, shutters on landing surface  504  are opened to reveal wind power generation modules  506 . Air turbulence  508 , resulting from remote vehicle  502  coming in for a landing on landing surface  504 , passes through the opened shutters to interact with wind power generation modules  506  to generate power. Portions of landing surface  504  are deformed to encircle the portion of landing surface  504  where remote vehicle will land to maximize power generation from air turbulence  508 , adjusting the positions of the wind power generation modules attached to the deformed portions of landing surface  504 .

When shutter  602 B is opened, as shown in diagram  600 B, wind power generation module turbine  604 B is exposed to oncoming air turbulence, such as that generated by operations of remote vehicles as previously discussed. In such a configuration, wind power generation module turbine  604 B generates power from the resulting interactions with nearby air turbulence.

     In an Including/include/includes: unless otherwise explicitly noted, means “including but not necessarily limited to.” 
     Module/Sub-Module: any set of hardware, firmware and/or software that operatively works to do some kind of function, without regard to whether the module is: (i) in a single local proximity; (ii) distributed over a wide area; (iii) in a single proximity within a larger piece of software code; (iv) located within a single piece of software code; (v) located in a single storage device, memory or medium; (vi) mechanically connected; (vii) electrically connected; and/or (viii) connected in data communication.

     Without substantial human intervention: a process that occurs automatically (often by operation of machine logic, such as software) with little or no human input; some examples that involve “no substantial human intervention” include: (i) computer is performing complex processing and a human switches the computer to an alternative power supply due to an outage of grid power so that processing continues uninterrupted; (ii) computer is about to perform resource intensive processing, and human confirms that the resource-intensive processing should indeed be undertaken (in this case, the process of confirmation, considered in isolation, is with substantial human intervention, but the resource intensive processing does not include any substantial human intervention, notwithstanding the simple yes-no style confirmation required to be made by a human); and (iii) using machine logic, a computer has made a weighty decision (for example, a decision to ground all airplanes in anticipation of bad weather), but, before implementing the weighty decision the computer must obtain simple yes-no style confirmation from a human source. 
     Automatically: without any human intervention. 
     We: this document may use the word “we,” and this should be generally be understood, in most instances, as a pronoun style usage representing “machine logic of a computer system,” or the like; for example, “we processed the data” should be understood, unless context indicates otherwise, as “machine logic of a computer system processed the data”; unless context affirmatively indicates otherwise, “we,” as used herein, is typically not a reference to any specific human individuals or, indeed, and human individuals at all (but rather a computer system).
