Suitable signal formats may be embodied in analog or digital form, with or without error detection and/or correction bits, packet headers, network addresses in a specific format, and/or other supporting data readily provided by those of skill in the pertinent art.
The processor 104 is in electrical communication with a docking station 108 that includes one or more docking ports 110 for electrically interfacing with and charging a portable device 112. The docking ports 110 may further enable the transfer of data and instruction code to update the portable devices 112 as needed. The base device 102 may include a wireless interface 114 to enable wireless communication with a portable device 112. Wireless communication may be based on a proprietary communication protocol.
The base device 102 also includes input device(s) 116 that may include a keyboard, mouse, touch screen, light pen, tablet, microphone, sensor, or other hardware with accompanying firmware and/or software. The base device 102 includes output device(s) 118 that may include a monitor or other display, printer, speech or text synthesizer, switch, signal line, or other hardware with accompanying firmware and/or software.
The base device 102 may further include a network interface 120 such as a router, network card, modem, or the like to enable network communication between the base device 102 and a central server and/or remote devices. The network interface 120 is suitable for communication across a local area network, wide area network, metropolitan area network, and/or “Internet” or IP networks such as the World Wide Web, a private Internet, a secure Internet, a value-added network, a virtual private network, an extranet, an intranet. One suitable network includes a server and several clients; other suitable networks may contain other combinations of servers, clients, and/or peer-to-peer nodes, and a given computer may function both as a client and as a server.
To minimize installation issues at a customer location, the network interface 120 may be embodied as a cellular data modem. The cellular data requires no external phone connections and provides a highly reliable communication system. It would also allow more flexible placement of the base device 102 in a golf shop or club house.
The base device 102 may be further embodied with a floppy drive, tape drive, optical drive, magneto-optical drive, or other means to read a storage medium. A suitable storage medium includes a magnetic, optical, or other computer-readable storage device having a specific physical configuration. Suitable storage devices include floppy disks, hard disks, tape, CD-ROMs, DVDs, PROMs, random access memory, flash memory, and other computer system storage devices. The physical configuration represents data and instructions that cause the computer system to operate in a specific and predefined manner as described herein.
The memory 106 includes instruction code to perform in accordance with the operations discussed herein. Specifically, the memory 106 includes an operating system 122 and an accounting module 124. The accounting module 124 includes an algorithm to monitor use of each portable device 112 and calculate a royalty for a system provider based on use.
The base device 102 may also include a Global Positioning System (GPS) 25 to receive global position data. The base device 102 may use the global position data to establish the location of the base device 102 relative to portable devices 112 and holes on the golf course.
A portable device 112 may be embodied as a hand-held device that is configured for ergonomic convenience. The portable device 112 is designed for outdoor environments in temperatures ranging from 0° C. to 70° C. and are water resistant. A portable device 112 includes a housing 126 to contain the components thereof. Each portable device 112 includes a GPS receiver 128 such as a Wide Area Augmented System (WAAS) enabled GPS receiver for communicating with one or more GPS satellites 130. The WAAS signal was originally developed for the FAA to reduce the positional error of a traditional GPS receiver so that its performance is adequate for commercial aircraft instrument landing systems. Unlike traditional Differential GPS (DGPS), the WAAS signal is broadcast on the same frequencies as the GPS signals. This eliminates the need for a separate and expensive dedicated DGPS receiver.
A portable device 112 further includes a processor 132 and a memory 134 that are in electrical communication with the GPS receiver 128 to receive global position data. Both the processor 132 and memory 134 may be implemented in any number of ways including the embodiments discussed in reference to the base device 102. The memory 134 includes an operating system 136 to perform the necessary instructions to enable interaction of the portable device 112 with a GPS to thereby allow users to determine geographic position. The memory 134 further includes a distance computation module 138 to determine distance to terrain features and holes as discussed below. Each portable device 112 may further include a wireless interface 140 to enable two-way communication with the wireless interface 114 of the base device 102.
The portable device 112 may include a rechargeable battery 142 that is in electrical communication with the processor 132 and a docking interface 144. The docking interface 144 is to couple with a port 110 to recharge the battery 142.
The portable device 112 includes a display 146 that may be embodied as any number of devices including LCD, LED, and the like. The portable device 112 further includes an input device 148, such as a keypad, that allows for golfer input to enable various functions of the portable device 112. The number of keypad buttons is preferably limited to reduce golfer confusion. In order to compensate for the limited keypad, the portable device 112 may provide an intuitive GUI to facilitate operation.
The base device 102 may be resident at a golf course, such as in a club house. A golfer may request and rent a portable device 112 for a fee. Portable devices 112 are coupled to respective docking ports 110. The coupling allows the portable devices 112 to recharge their batteries 142 and allows for data transfer. Data transfer between a base device 102 and a portable device 112 may also be achieved through a wireless communication.
During data transfer, the portable device 112 may receive golf course data to assist in locating a golfer's position relative to holes, greens, hazards, bunkers and other pertinent information regarding the play of a golf course. Thus, golf course data may include hole position data to identify the location of each hole. Golf course data may further include the locations and dimensions of greens, hazards, bunkers, and so forth. Golf course data may further include data specific to each green such as slope of the front, center, and back of each green regardless of a golfer's angle of approach. Green data is therefore relevant to a golfer who is on the fairway and to a golfer who is 45 degrees to the right after experiencing a slice. Golf course data may further include information about the characteristics of each hole that are important to game play.
As golf course terrain and features may change, the golf course data must be updated in the base device 102. Hole positions routinely change, and hole position data must be reentered into the base device 102. Golf course data may be entered manually into the base device 102 through an input device 116. Alternatively, a user may position a portable device 112 to the approximate location of a hole or other golf course feature. The user then enters a hole number into the portable device 112 and stores corresponding global positioning data which becomes the hole position data. This technique is performed for each hole. The portable device 112 may communicate the hole position data to the base device 102 through either wireless communication or direct coupling. A golf course facility may daily send an employee through the course with a portable device 112 to ensure the accuracy of the hole position data. As can be appreciated, rented portable devices 112 are precluded from updating hole position data.
Referring to FIG. 2, a flow diagram illustrates a process 200 performed by the system 100. A portable device 112 is charged 202 by docking the device 112 with the base device 102. The base device 102 transfers 204 golf course data including hole position data to the portable device 112 through a docking interface or through wireless communication. The portable device 112 is released 206 from its corresponding docking port. The accounting module 124 registers 206 the release of the portable device 112 and records the time. The accounting module 124 may further register the return and time of a portable device 112. After a certain time period, the accounting module 124 considers the released portable device 112 to be an income event. Each income event may be recorded to determine revenue generated by the system for each day, week, and so forth. A summary of income events may be transmitted through the network interface 120 to a remote location for accounting purposes. A system manager is in this way informed of the system use and licensing royalties that are due.
A golfer traverses a golf course with the portable device 112 and has access to the golf course data. The portable device 112, through its GPS receiver, receives 208 global position data and continuously updates its location. The portable device 112 may communicate 210 its location through the wireless interface 140 to the base device 102. The base device 102 may receive the locations of each portable device 112 on the course.
The distance computation module 138 computes 212 the distance to holes proximate to the golfer based on hole and global position data. The distance computation module may further compute 214 the distance to other features such as hazards, the perimeter and center of a green, bunkers, and so forth. The portable device 112 may display 216 all such distance computations to the golfer. Information specific to a green and hole may also be stored in the portable device 112 and retrieved as requested. Thus, a golfer's position relative to a hole, green perimeter, green center, fairway, hazard, and bunker is accessible at all times.
As a golfer reaches a certain distance to a hole, the portable device 112 may automatically display the hole number and associated distance. The portable device 112 may further automatically display the distance to hazards and/or bunkers and information on the green. The distance computation module 138 may include an algorithm to automatically display information associated with a hole that a golfer is likely playing. Once a golfer passes a hole and traverses a certain distance, the computation module 138 may automatically display the next hole and associated information. Automatic, sequential advancement to the next hole conveniently allows a golfer to review distance without entering the current hole being played. Alternatively, a golfer may enter a hole number and the portable device 112 responds by displaying the associated information. The portable device 112 may further update the displayed distance as the golfer proceeds. Upon completion of a hole, the golfer may enter the next hole number and receive its associated information. In one implementation, the portable device 112 may automatically display hole distance or require user entry based on a selected option.
The base device 102 may also transmit distance between the base device 102 and the portable device 112. If desired, the portable device 112 can display base device proximity to the golfer. Upon game completion, the golfer returns the portable device 112. The portable device 112 is once again coupled 218 to a docking port 110 for recharging. The accounting module 124 may record the return and update its associated records accordingly.
Referring to FIG. 3, a plan view of one embodiment of a portable device 300 is shown. A display 302 illustrates the hole and associated distance and options such as a return to menu or unlock. A keypad 304 may provide a few keys with an intuitive interface to facilitate user operation. A display 302 and keypad 304 may be implemented in various designs, all of which are within the scope of the invention.
Referring to FIG. 4, an embodiment of a graphical representation 400 is shown that a base device 102 may generate. The representation 400 illustrates a golf course with the location of each portable device 402 on the course. An operator can monitor the progress of golfers throughout the course. If desired, the base device 102 can include a display for observers in a clubhouse to monitor the progress of golfers. Golfers may be identified based on portable device identification and assigned a name for viewing purposes. In some embodiments, the portable device 112 may also provide a similar overview of the course with the golfer's location on the course.
The system described herein provides an accurate and reliable method for golfers to receive relevant distances and other course information during game play. A base device is able to communicate with portable devices to recharge and update information. A base device is further able to record use for accounting and monitor portable device locations throughout a golf course.
It will be obvious to those having skill in the art that many changes may be made to the details of the above-described embodiments without departing from the underlying principles of the invention.
