Embodiments of the invention described in this specification relate generally to rail building systems, and more particularly, to a continuous serpentine concrete beamway forming system and a method for creating a hollow continuous serpentine concrete beamway suitable for high-speed monorail traffic and other transit profiles, including, without limitation, transit guideways, bike paths, sidewalks, and architectural features.
Existing methods for creating concrete beamways suitable for monorail type transit, involve precasting the beamways offsite, then transporting the completed beamways to the installation site. Heavy equipment is required to set the beamways in place. This process is expensive and time-consuming. The beamways created in this fashion contain irregularities in the surfaces of the beamways, as well as the potential for misalignment in the joints between the beamway sections.
Existing methods for casting concrete beamways do not use a contiguous form nor is there a reference datum cast into the beamways to be used for dressing the running surfaces.
Therefore, what is needed is a way to create precision rail segments and to be able to align the rail segments with the highest precision contemporaneously with creating the rail segments in order to quickly and efficiently build an overall rail system.
A novel continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway are disclosed. In some embodiments, the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway utilizes a flexible form material that has the ability to conform to curves, angles, and slopes of a target beamway system as intended. In some embodiments, the flexible form material is used to form an armature that embodies a precise pathway of the target beamway system. In some embodiments, the armature is contiguous throughout a plurality of connected beamway segments that collectively make up the target beamway system and that are precisely aligned to conform to the curves, angles, and slopes of the target beamway system. In some embodiments, a part of the armature creates grooves on the surfaces of the connected beamway segments. In some embodiments, the grooves are subsequently used to guide machinery that grinds the running surfaces to precise tolerances. In some embodiments, precise alignment is achieved as a result of the grooves being formed in a continuous fashion, thereby allowing the grinding machines to cross from one beamway segment to the next.
In some embodiments, the method for creating a hollow continuous serpentine concrete beamway includes performing initial survey procedures according to a beamway measuring system (BMS), performing ground interface procedures, starting scaffold erection, performing tray adjustments, pouring concrete for the bottom of the target beamway rail, placing and adjusting armature brackets to create an armature structure, placing and adjusting fiberglass tubes in relation to the armature structure, printing concrete sides and the top of the beamway rail, removing beamway forming apparatus, and dressing the beamway rails.
The preceding Summary is intended to serve as a brief introduction to some embodiments of the invention. It is not meant to be an introduction or overview of all inventive subject matter disclosed in this specification. The Detailed Description that follows and the Drawings that are referred to in the Detailed Description will further describe the embodiments described in the Summary as well as other embodiments. Accordingly, to understand all the embodiments described by this document, a full review of the Summary, Detailed Description, and Drawings is needed. Moreover, the claimed subject matters are not to be limited by the illustrative details in the Summary, Detailed Description, and Drawings, but rather are to be defined by the appended claims, because the claimed subject matter can be embodied in other specific forms without departing from the spirit of the subject matter.
Having thus described the invention in general terms, reference is now made to the accompanying drawings, which are not necessarily drawn to scale, and which show different views of different example embodiments, and wherein:
In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications.
Some embodiments of the invention include a novel continuous serpentine concrete beamway forming system and a novel method for creating a hollow continuous serpentine concrete beamway. In some embodiments, the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway utilizes a flexible form material that has the ability to conform to curves, angles, and slopes of a target beamway system as intended. In some embodiments, the flexible form material is used to form an armature that embodies a precise pathway of the target beamway system. In some embodiments, the armature is contiguous throughout a plurality of connected beamway segments that collectively make up the target beamway system and that are precisely aligned to conform to the curves, angles, and slopes of the target beamway system. In some embodiments, a part of the armature creates grooves on the surfaces of the connected beamway segments. In some embodiments, the grooves are subsequently used to guide machinery that grinds the running surfaces to precise tolerances. In some embodiments, precise alignment is achieved as a result of the grooves being formed in a continuous fashion, thereby allowing the grinding machines to cross from one beamway segment to the next.
In some embodiments, the method for creating a hollow continuous serpentine concrete beamway includes performing initial survey procedures according to a beamway measuring system (BMS), performing ground interface procedures, starting scaffold erection, performing tray adjustments, pouring concrete for the bottom of the target beamway rail, placing and adjusting armature brackets to create an armature structure, placing and adjusting fiberglass tubes in relation to the armature structure, printing concrete sides and the top of the beamway rail, removing beamway forming apparatus, and dressing the beamway rails.
As stated above, existing methods for creating concrete beamways suitable for monorail type transit, involve precasting the beamways offsite, then transporting the completed beamways to the installation site. Heavy equipment is required to set the beamways in place. As such, the existing methods are problematic, being expensive and time-consuming. The beamways created in this fashion contain irregularities in the surfaces of the beamways, as well as the potential for misalignment in the joints between the beamway sections. Thus, the problems of the existing methods go beyond expense and time, having an effect on quality of the constructed beamway which impacts performance and may increase risks to riders. Embodiments of the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway described in this specification solve such problems by enabling quick and efficient creation of concrete beamways suitable for monorail-type transit, on site. In some embodiments, the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway can create a beamway system faster and cheaper than other methods. The beamways created by this process have precision surfaces, as well as precise alignment between segments.
Embodiments of the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway described in this specification differ from and improve upon currently existing options. In particular, some embodiments of the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway differ by avoiding the challenge and expense of casting beamways offsite by using a mobile 3-D printing system to effectively create beamways onsite and in place.
Embodiments of the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway described in this specification use survey equipment connected to a computerized system which plots the course of the intended/target beamway rail in virtual space. The continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway also designs and engineers the scaffold system required to build the beamway rail. This scaffold system is used to position the equipment required for this process. This collection of hardware and software is referred to as the beamway measuring system or (BMS).
The process for creating a rail operates as a mobile assembly line with the processing equipment moving forward while the “product,” the rail, remains stationary.
The process begins with scaffolding being erected at the beginning point of the route and continuing to be erected along the route of the rail. Once the scaffolding reaches an adequate length, the scaffolding that was erected at the starting point is dismantled and continues to be dismantled at a rate roughly equal to the forward progress of the scaffold erection process. In this fashion, the scaffold structure steps forward one scaffold frame at a time.
A stable ground interface for the scaffold structure is accomplished by ties set on top of blocking that is stacked to create a level footing. Wedges accommodate an additional leveling process. The ties are fastened firmly to the ground with tackle and anchors. Buttress stabilize the scaffolding at locations indicated by the BMS. Scaffolding is erected on top of the ties. The scaffolding is used to support the equipment, material, and personnel required for this process.
The scaffolding is allowed to follow curves by reason of slip joints built into the crossbar members. When tightened, these slip joints cause the scaffolding to become rigid.
The scaffolding is outfitted with two levels of decking. The decking is used for work surfaces as well as to transport personnel, equipment, and materials. Automated carts operate on the lower level. They carry sections of scaffolding, deck boards, and other items from the rear of the scaffolding up to the front.
Square shaped rails are mounted along each side of the top of the scaffolding structure. These rails are used by a number of different mechanisms. One such device is a crane that facilitates the erection of the scaffolding at the front of the mechanism. A similar crane facilitates the dismantling of the scaffolding at the rear of the mechanism. The crane at the front of the mechanism is followed by a machine which carries a supply of deck boards and sets them into position with robotic arms.
Also riding on these rails are two trains which transport bags of premixed concrete from a loading site to the processing sites. Each train is equipped with an automated sack handler which loads sacks of premixed concrete onto automated carts which drive themselves up to the front of the train where a second automated sack handler moves the sacks one by one off of the carts and onto a loading mechanism. The loading mechanism lifts the sacks up to a conveyor which delivers them to a hopper which feeds the premixed concrete into a mixer. From there, a pump delivers it to various printing and pouring operations below the train. These trains are reloaded by a pair of pallet lifters attached to the scaffold structure.
The rail fabrication process takes place on the upper level of decking. This process begins with the installation of a line of trays supported by support braces. A machine sets the support bases and a second machine sets trays onto the support braces. The scaffold structure is wired with AC power. The support braces are equipped with servo motors which are connected to the AC power system. The servo motors are connected by means of a local wireless network to the BMS which automatically positions them to the correct location. A steel guide rod connects to the sides of the support braces. This rod will subsequently connect the printing mechanisms to the tray assembly.
The trays serve as a platform to support the required rebar and wire mesh. Next a concrete spreading machine fills the trays with concrete. Brackets set into the wet concrete are adjusted to precise location with the aid of the BMS and held in position with mounting braces until the concrete has set.
After the concrete has cured, these brackets support an armature made from woven mats of a flexible forming material called StrawJet. The StrawJet material is made up of tightly compressed columns of palm fronds or similar tough fibrous material bound into a long cylinder. This material possesses properties of both stiffness as well as flexibility which allows it to conform to curves and serpentine shapes, while at the same time producing a rigid structure when assembled in the above described manner.
This armature structure is used to support wire mesh and other reinforcing materials. Fiberglass tubes are suspended on either side of the armature structure held in place by means of alignment brackets screwed onto the armature structure. These brackets also accommodate the fine adjustment of the position of the fiberglass tubes. An alignment jig is used to ensure the precise positioning of the tubes in relationship to the armature structure.
Carts fitted with 3-D printing apparatus form a train of six or more carts. They straddle the armature structure and roll along the deck on wheels. Once in position, the printing devices connect to the armature assembly by means of the steel guide rods. Foam dams inserted between the printing devices and the armature structure prevent the wet concrete from spilling out the sides of the area to be printed. The printing mechanisms print the sides and top of the rail. This happens in two stages; first up to just above the fiberglass tubes and then after the concrete has set, the alignment brackets are removed and the process continues to the top of the rail. This happens quickly because the concrete used in this process, and all of the other procedures described in this invention, is made using magnesium oxide-based cement as a binder rather than Portland cement. The magnesium oxide cement-based concrete sets much faster and is more durable than Portland cement-based concrete.
A mold mechanism in the form of a flexible tambour that rolls out from a cassette, is positioned just below and is connected to the printing mechanism so that when the printing mechanism moves up to deposit another course of concrete, the mold mechanism moves with it. This creates a confined space for the concrete to be deposited into. A sheet of flexible plastic positioned between the concrete and the tambour prevent the concrete from fouling the tambour mechanism. A vibrating roller built into the tambour cassette settles the concrete to eliminate voids. The train of printing carts print the rail in an “every-other” pattern leaving patches of printed rail and spaces of roughly equal size. For example, a printing cycle will leave every other space printed, then the train of printing carts jogs forward to fill-in the spaces.
With the printing process complete, the process of pouring the posts begins. Once the posts for a length of rail are complete the trays and support braces are disassembled and loaded onto carts that shuttle the equipment to the front of the scaffolding for reuse.
Two grinding machines progress slowly down the rail in the same direction as the fabrication process is moving. The first of these grinders dresses the top of the rail to the precise tolerance and texture. The second grinding machine grinds two pathways on either side of the rail to form the rolling surfaces for the vehicles that will ride on the rail.
Both of the grinding machines utilize the grooves left as impressions on either side of the finished rail as a reference datum to guide their progress. They ride on wheels that fit precisely into the grooves. The wheels are mounted into bogies in groups of three or more. Four such bogies attach to each of the grinding machines. The outer surface of these wheels is made out of urethane having a durometer measurement of 102 A±10. These groupings of relatively hard wheels which fit precisely into the grooves, promotes the accuracy of the grinding process.
In addition, some embodiments of the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway improve upon the currently existing options by using a flexible form material that allows for precision contouring around curves, angles, and slopes of the target (or intended) beamway system. Specifically, in order to create beamways suitable for high-speed monorail traffic, the running surfaces of the beamways need to be precise and the beamway segments need to align precisely. The use of a non-contiguous casting system, such as those from the existing methods, results in a beamway structure with irregularities in the running surfaces and misalignment at the junctures between beamway segments. The lack of a method for casting a contiguous datum determines that there is no convenient way to grind imperfections from the beamway system. In contrast, embodiments of the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway described in this specification utilize flexible form material that has the ability to conform to the curves, angles, and slopes of the intended beamway system, and is used to form an armature that precisely embodies the path of the beamway system. This armature is contiguous throughout a line of connected beamways. Part of this armature creates grooves on the exterior of the beamways which are subsequently used to guide machinery that grinds the running surfaces to precise tolerances and because the grooves are formed in a continuous fashion, precise alignment is achieved when the grinding machines across from one beamway segment to the next.
The continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway of the present disclosure may be comprised of the following elements. This list of possible constituent elements is intended to be exemplary only and it is not intended that this list be used to limit the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway of the present application to just these elements. Persons having ordinary skill in the art relevant to the present disclosure may understand there to be equivalent elements that may be substituted within the present disclosure without changing the essential function or operation of the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway.
The continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway of the present disclosure generally works by using survey equipment connected to a computerized system which plots the course of the rail in virtual space. This system is used to position the equipment required for this process. This collection of hardware and software is referred to as the beamway measuring system (BMS). The method for creating a hollow continuous serpentine concrete beamway operates as a mobile assembly line with the processing equipment moving forward while the “product,” the rail, remains stationary.
The method for creating a hollow continuous serpentine concrete beamway begins with an initial survey (1) using optical and Lidar (65) type survey equipment. The results of the survey are fed into a computerized system which produces the path of the beamway system or “rail” (2) in virtual space. This software also designs and engineers a scaffold structure required to build the rail. We will call this collection of hardware and software the beamway measuring system or BMS (3). This system is used to position the physical components used in this process. Wooden blocking (4) is placed at the appropriate locations. A tie (68) is set on top of the blocking. Tie bars (67) slide through the ends of the ties. Wedges (70) level the assembly which is then pinned to the ground with tackle (61) and anchors (5). This process is referred to as the ground interface procedure (69). Scaffolding (6) is built on top of the connector ties. The scaffolding is composed of scaffold sections (62). The scaffolding is equipped with slip joints (58) on the ends of the crossbar members (59). Buttresses (57) brace the scaffolding. The erection of the scaffolding is called the scaffold erection process (71). The scaffolding supports most of the devices and equipment used in this process. The scaffolding is equipped with square rails (7) that run along the top of the scaffolding. Two cranes (8) ride on these rails, one at the front of the scaffolding and one at the rear of the scaffolding. A deck-board installer (9) carries and places deck-boards (10). A support brace installer (11) carries and attaches support braces (12). A tray installer (13) carries and places trays (14) on top of the support braces. A tray adjustment procedure (16) is accomplished by the positioning of the brace servomotors (15) according to instructions from the BMS. Steel guide rods (17) attach along the sides of the trays. The trays are filled with magnesium oxide cement (18)-based concrete by a concrete spreader (19). Armature brackets (20) are set into the concrete at intervals. The armature bracket adjustment (22) takes place aided by target fixtures (23) and the BMS. Mounting braces (21) hold the armature brackets in place while the concrete sets. The creation of the armature structure (24) takes place when mats made of StrawJet material (25) are fastened onto the armature brackets. Alignment brackets (27) attach to the armature structure (28). Fiberglass tubes (26) attach to the alignment brackets. The adjustment of the fiberglass tubes (29) takes place guided by the alignment jig (63). Connector plugs (56) are used to connect the fiber glass tubes. Foam dams (38) attach to the armature structure and act to contain the wet concrete during the printing process. Multiple printing carts (30) straddle the armature structure. Each cart is equipped with a printer frame (31) suspended by four servo actuators (32). Each printer frame is equipped with two printing mechanisms (33), one for printing one side of the rail, the other for printing the other side of the rail. Also mounted on the printer frame are a pair of tambour cassettes (34), consisting of a sliding tambour (35), a plastic shield (36) and a vibrating roller (37). The printing of the sides and top of the rail (39) occurs when wet concrete mix (73) is supplied to the printing mechanisms by means of a mixer train (41) that rides on the rails which are attached to the top of the scaffolding. The mixer train is composed of a mobile sack handler (42), a fixed sack handler (43), automated delivery carts (44), a loading mechanism (45), a conveyor (49), a hopper (46) a mixer (47), and a pump (48). Pallets are loaded with sacks of premixed concrete (66). Pallet lifters (50) connected to the scaffolding, load pallets of premixed concrete (60) onto the mixer trains. A top surface grinding machine (53) and a side surface grinding machine (54) perform the dressing of the rail procedure (52) guided by grooves (55) in the sides of the rail. Both of the grinding machines ride on wheels (72). The wheels are mounted on bogies (64). Scaffold carts (51) deliver the scaffold sections (62) from the rear of the scaffold structure to the front. The rail is held up by posts (40).
To make the continuous serpentine concrete beamway forming system and method for creating a hollow continuous serpentine concrete beamway of the present disclosure, the path of the beamway system or (rail) is first plotted using optical and Lidar type survey equipment coupled to a computerized modeling application which creates the path of the rail in virtual space. This collection of hardware and software is referred to as the beamway measuring system (BMS). This system is used to position the location and height of the wooden blocking, the position and height of the scaffolding, as well as other equipment and components. Lidar devices are initially mounted on tripods and then subsequently mounted onto the scaffolding itself.
When the route for the rail is surveyed, markers are placed on the ground indicating the positions for the wooden blocking as well as the locations of the support posts. Holes are dug for the support posts. Wooden blocking is placed on and built to the required height on the markers and anchored to the ground. Scaffolding is positioned on the blocking and erected to the required height.
The scaffolding is fitted with deck boards. Trays are installed using support braces. The trays are adjusted to the desired position and angle with the help of target fixtures and the BMS. Steel guide rods are fastened to the support braces that hold up the trays.
Rebar and other reinforcing materials are placed in the trays and are supported above the surface of the trays on wire stands. The trays are subsequently filled with concrete.
Armature brackets are set into the wet concrete and adjusted to the precise location with the help of target fixtures and the BMS. Mounting braces are used to hold the armature brackets in place until the concrete has set.
Mats made of flexible forming material, such as StrawJet material, are screwed onto the armature brackets with the sections of mat overlapping one another in such a way as to create a continuous armature structure. Wire braces are screwed onto the armature that are used to support wire mesh and rebar.
Alignment brackets are screwed onto the armature structure and fiberglass tubes are fitted into each side of the brackets. Connector plugs inserted into the ends of the tubes allow them to link together thus creating the effect of a continuous unit. The result is two fiberglass tubes running parallel to each other on either side of the armature fixture. The positioning of these tubes is the most critical aspect of the entire operation and great care is taken to ensure that their position is accurate. An alignment jig is used to help with this process. The position of the tubes is locked in place by an adjustment mechanism built into the alignment brackets. This process is guided by an alignment jig.
During the printing process that follows, great care is taken to not disturb the position of the fiberglass tubes. The printing process is accomplished by positioning printing carts over the area to be printed then carefully lowering the printing frame mounted on each cart into position and clamping it onto the steel guide rods. With the printing mechanism in place, the printing of the sides and top of the rail can begin. When the concrete reaches a level just above the fiberglass tubes, the process is halted until the concrete has set. Once the concrete has set, the alignment brackets can be removed to allow the printing to continue until completion. Once the concrete has set, the printing carts are moved towards the front of the scaffolding and the pouring of the posts can begin.
With the posts in place, the fiberglass tubes, the support braces, and the trays can be removed from around the rail. Grinding machines are then used to dress the rail. The scaffolding is dismantled and the sections loaded onto carts which navigate by computer control to the front of the scaffold where the process is repeated.
By way of example,
An example of an initial survey procedure is described by reference to
After the initial survey with the ground markers is completed, the initial survey process 200 performed by the BMS includes a step to use survey equipment to establish the height of wooden blocking (at 220). In some embodiments, the wooden blocking varies in height such that scaffolding will be erected to be level. Since ground surfaces vary and have many differences in relative heights across the expected path of the target beamway, establishing the height of wooden blocking is a fundamental step carried out by the BMS.
In some embodiments, the initial survey process 200 performed by the BMS also includes a step for using the survey equipment to establish the height of the scaffolding (at 230). The height of the scaffolding, for example, can be based on a scaffold structure that supports at least two deck levels and a rail system that tops the scaffold above the two deck levels. However, in some embodiments, the relative height of different sections of scaffolding along the target beamway path may vary according to the intended height of the target beamway expected to be built via the continuous serpentine concrete beamway forming system. For example, the expected height of the target beamway may intend to smooth out variations in the height of the ground over a certain section of the path (e.g., a particular section of the path that has many small hills and valleys over a short span).
In some embodiments, the initial survey process 200 performed by the BMS next uses survey equipment to establish the positions and angles of support braces (at 240). The positions and angles of the support braces may vary as much as the relative and/or varying height of the scaffolding used in the construction of the target beamway, and therefore, needs to be established prior to moving forward to construction.
Finally, the initial survey process 200 performed by the BMS of some embodiments includes a step to use survey equipment to establish the positions of armature brackets (at 250). The armature brackets are later used in the forming and construction of the armature structure, which is used subsequently for the concrete printing process that creates the final beamway rail as intended. Then the initial survey process 200 performed by the BMS ends.

Examples of ground interface procedures and scaffold erection are described next by reference to
In some embodiments, the scaffold erection process 300 proceeds to attach the sections of scaffolding to ties and to bolt the sections of scaffolding together (at 330) in order to achieve a desired height for the scaffolding structure. Again, the overhead crane may be helping to deliver sections of scaffolding to higher levels where human, non-human autonomous, or non-human semi-autonomous operators wait to attach and bolt the sections of scaffolding into place. In some embodiments, the scaffold erection process 300 uses the scaffolding to support the continuous serpentine concrete beamway forming process (at 340).
In some embodiments, as the scaffolding structure is being assembled, the scaffold erection process 300 dismantles scaffolding (at 350) when the continuous serpentine concrete beamway forming process is complete in relation to one or more segments of beamway. In some embodiments, the scaffold erection process 300 then loads (at 360) sections of scaffolding onto scaffold carts with the help of the overhead crane. Next, the scaffold erection process 300 delivers the sections of scaffolding on the scaffold carts to the front end of the scaffold assembly/structure (at 370). Then the scaffold erection process 300 ends. While the scaffold erection process 300 is complete for erected scaffolding for one or more segments of the target beamway, it is noted that the scaffold erection process 300 is repeated over and over until the target beamway is fully constructed.

A key feature of the continuous serpentine concrete beamway forming system is that it is able to print concrete beamway rails at location and just in time according to the scaffolding structure state. A mixer train is employed in some embodiments to provide a continuous supply of concrete for the printing of the beamway rails. The next several descriptions relate to such a mixer train that is deployed on the square rails at the top of the scaffolding structure, to enable a steady supply of wet concrete to be supplied to the print carts to print the sides and top of the beamway rails.

Many of the above-described features and applications are implemented as software processes that are specified as a set of instructions recorded on a computer readable storage medium (also referred to as computer readable medium or machine readable medium). When these instructions are executed by one or more processing unit(s) (e.g., one or more processors, cores of processors, or other processing units), they cause the processing unit(s) to perform the actions indicated in the instructions. Examples of computer readable media include, but are not limited to, CD-ROMs, flash drives, RAM chips, hard drives, EPROMs, etc. The computer readable media does not include carrier waves and electronic signals passing wirelessly or over wired connections.
In this specification, the term “software” is meant to include firmware residing in read-only memory or applications stored in magnetic storage, which can be read into memory for processing by a processor. Also, in some embodiments, multiple software inventions can be implemented as sub-parts of a larger program while remaining distinct software inventions. In some embodiments, multiple software inventions can also be implemented as separate programs. Finally, any combination of separate programs that together implement a software invention described here is within the scope of the invention. In some embodiments, the software programs, when installed to operate on one or more electronic systems, define one or more specific machine implementations that execute and perform the operations of the software programs.
The bus 2505 collectively represents all system, peripheral, and chipset buses that communicatively connect the numerous internal devices of the electronic system 2500. For instance, the bus 2505 communicatively connects the processing unit(s) 2510 with the read-only 2520, the system memory 2515, and the permanent storage device 2525.
From these various memory units, the processing unit(s) 2510 retrieves instructions to execute and data to process in order to execute the processes of the invention. The processing unit(s) may be a single processor or a multi-core processor in different embodiments.
The read-only-memory (ROM) 2520 stores static data and instructions that are needed by the processing unit(s) 2510 and other modules of the electronic system. The permanent storage device 2525, on the other hand, is a read-and-write memory device. This device is a non-volatile memory unit that stores instructions and data even when the electronic system 2500 is off. Some embodiments of the invention use a mass-storage device (such as a magnetic or optical disk and its corresponding disk drive) as the permanent storage device 2525.
Other embodiments use a removable storage device (such as a floppy disk or a flash drive) as the permanent storage device 2525. Like the permanent storage device 2525, the system memory 2515 is a read-and-write memory device. However, unlike storage device 2525, the system memory 2515 is a volatile read-and-write memory, such as a random access memory. The system memory 2515 stores some of the instructions and data that the processor needs at runtime. In some embodiments, the invention's processes are stored in the system memory 2515, the permanent storage device 2525, and/or the read-only 2520. For example, the various memory units include instructions for processing appearance alterations of displayable characters in accordance with some embodiments. From these various memory units, the processing unit(s) 2510 retrieves instructions to execute and data to process in order to execute the processes of some embodiments.
The bus 2505 also connects to the input and output devices 2530 and 2535. The input devices enable the user to communicate information and select commands to the electronic system. The input devices 2530 include alphanumeric keyboards and pointing or cursor control devices. The output devices 2535 display images generated by the electronic system 2500. The output devices 2535 include printers and display devices, such as cathode ray tubes (CRT) or liquid crystal displays (LCD). Some embodiments include a touchscreen that functions as both an input and output device.
Finally, as shown in
These functions described above can be implemented in digital electronic circuitry, in computer software, firmware or hardware. The techniques can be implemented using one or more computer program products. Programmable processors and computers can be packaged or included in mobile devices. The processes and logic flows may be performed by one or more programmable processors and by sets of programmable logic circuitry. General and special purpose computing and storage devices can be interconnected through communication networks.
Some embodiments include electronic components, such as microprocessors, storage and memory that store computer program instructions in a machine-readable or computer-readable medium (alternatively referred to as computer-readable storage media, machine-readable media, or machine-readable storage media). Some examples of such computer-readable media include RAM, ROM, read-only compact discs (CD-ROM), recordable compact discs (CD-R), rewritable compact discs (CD-RW), read-only digital versatile discs (e.g., DVD-ROM, dual-layer DVD-ROM), a variety of recordable/rewritable DVDs (e.g., DVD-RAM, DVD-RW, DVD+RW, etc.), flash memory (e.g., SD cards, mini-SD cards, micro-SD cards, etc.), magnetic and/or solid state hard drives, read-only and recordable Blu-Ray® discs, ultra density optical discs, any other optical or magnetic media, and floppy disks. The computer-readable media may store a computer program that is executable by at least one processing unit and includes sets of instructions for performing various operations. Examples of computer programs or computer code include machine code, such as is produced by a compiler, and files including higher-level code that are executed by a computer, an electronic component, or a microprocessor using an interpreter.
While the invention has been described with reference to numerous specific details, one of ordinary skill in the art will recognize that the invention can be embodied in other specific forms without departing from the spirit of the invention. For instance,
