A modular voting machine displays a portion of ballot across a number of distinct physical locations on the voting machine. A block of memory is allocated to each of the physical locations which display a portion of the ballot. The blocks of memory are configured by voting officials to associate the physical location on the voting machine with the portion of an actual ballot that is displayed at that physical location. Once the blocks of memory have been configured by voting officials, the information contained in the blocks of memory may be used by a processor to verify a voter's selection of a portion of the ballot displayed at the associated physical location. Once a voter complete his or her selections, the voting machine may record the votes in an internal, encapsulated memory device.
This invention relates to automated vote counting.
Recent elections have highlighted the need for accurate, reliable, and inexpensive vote counting systems which are simple for a voter to use and for an election official to set up. Some current automated voting systems use machine-readable punch cards in which a voter punches out a “chad” on a punch card using a stylus to indicate his or her vote. The completed punch card is then fed through a machine which reads the punch cards and tabulates the votes. If a voter fails to completely punch out the “chad”, the card-reader machine may not be able to read the card and thus not count the vote. In close elections, these machine-rejected ballots may be examined by voting officials for evidence (e.g., a hanging or dimpled “chad” which has not been completely punched out) of the voter's intent. When the results of an election hinge on these machine-rejected votes, determination of voter's intent by voting officials examining punch cards can be a contentious and controversial issue. Accordingly it may be desirable to provide an inexpensive, tamper-resistant and easy-to-use automated voting machine to use in lieu of a punch-card system.

The following detailed description describes a modular voting machine having hot-swappable electronic modules so that if a component fails, the module containing the failed component may be replaced without loss of counted votes. Additionally, the voting machine is configured using a set up process described below rather than by traditional software programming. The set up process is used to configure the voting machine for a particular election by one or more technicians who push buttons on a touch-screen or other input device to input data about the portion of the ballot that appears at a particular physical location on the voting machine. In operation, a voter may select an input device, such as a button, associated with a physical area on the voting machine which displays a portion of a ballot (e.g., a candidate's name). In response to a voter's selection, the voting machine can automatically verify the validity of a voter's selection by reading the set up information associated with the physical location selected by the voter. Moreover, vote counting occurs in a secure, tamper-resistant environment because the actual vote counting occurs in an embedded system that has been encapsulated at the factory before the voting machine is shipped and is inaccessible to local voting officials and technicians.
As shown in FIG. 1, a voting machine 10 includes an embedded processor 12 which executes an operating system (not shown) is connected to two voting modules 14 a-14 b, a touch-screen display 16, a printer 18, an electrostatic input device 20, and a record votes button 22. Additionally, a ballot card holder 24 a-24 b is located next to each of the voting modules 14 a-14 b. Each ballot card holder 24 a-24 b holds a printed ballot card 26 a-26 b. After a printed ballot card 26 a-26 b is placed in a ballot card holder 24 a-24 b, a seal 28 a-28 b is placed on an edge of each ballot card holder 24 a-24 b in order to prevent tampering with the printed ballot card 26 a-26 b.
Each voting module 14 a-14 b includes a number of voting buttons (30 a-30 c and 30 d-30 f) and corresponding indicator lights (32 a-32 c and 32 d-32 f). When an active voting button is selected, the corresponding indicator light will illuminate to indicate a valid selection. Similarly, if a voter changes his or her vote and deselects an active button by pressing the button a second time, the corresponding indicator light is shut off.
Each voting button and corresponding indicator light is associated with a candidate name location (e.g., “Candidate Name Location A” in FIG. 1) within each ballot card holder 24 a-24 b by the embedded processor 12. Each candidate name location corresponds to an actual physical location on the voting module where a portion of a ballot is displayed. The combination of a candidate name location and the associated vote selection button (30 a-30 c and 30 d-30 f) and indicator light (32 a-32 c and 32 d-32 f) make up a candidate space location. As will be described in greater detail later, each candidate space location is assigned a permanent address location in the memory of the embedded processor 12 that stays the same election after election, even though the names of the candidates presented in a particular candidate name location on the printed ballot card changes from one election to the next.
The voting machine 10 supports hot-swapping of electronic components should a component (e.g., voting module 14 a-14 b, touch-screen display 16, printer 18, electrostatic input device 22) or a part of a component (e.g., a voting button 30 a-30 f or indicator light 32 a-32 f) fail during the election. A hot-swappable component is one in which may be added or removed from the voting machine while the voting machine is running and have the operating system automatically recognize the change
Voting machine 10 also includes a touch-screen display 16 which, as will be described in greater detail below, is used by voting officials to configure the voting machine for a particular election. In addition, the touch-screen display 16 may be used during the election process by voting officials to view cumulative vote totals before the polls open (which should read zero for each candidate location) and throughout the voting process. In other separate embodiments, the voting machine may include one or more displays to display the ballot in lieu or in addition to the printed ballot cards. If one or more displays electronically displays the ballot, the voting machine may be configured to permit a voter to change the language of the ballot presented on the display.
Additionally, a printer 18 is included within voting machine 10 which may be used to print a voting receipt for each voter after he or she presses the record votes button 22. The printer 18 may also be used by voting officials to print election results during and after the voting process. While the touch-screen display 16 and printer 18 are shown to be integrated within the voting machine 10 in FIG. 1, in other separate embodiments one or both of these devices could be external to the voting machine and connected via cable or a wireless modem.
An electrostatic input device 20 functions as a write-in mechanism for voting machine 10 and is connected to the embedded processor 12. If a voter elects to write-in a candidate, he or she may do so by writing the person's name on the electrostatic input device 20 with a stylus. The electrostatic input device 20 records an image of the name of the candidate written in by the voter which will be later printed out and hand-counted by election officials. In a separate embodiment, text-recognition software may be included in embedded processor 12 in order to convert the hand written image into ASCII character text. Additionally, the write-in mechanism need not be an electrostatic input device, but could also be other electronic input devices commonly known such as a keyboard or a touch-screen.
In another embodiment, a printer (e.g., printer 16 shown in FIG. 1) may function as a write-in device. In this embodiment, when a voter indicates a desire to write-in a candidate, the printer prints out the candidate space location on a piece of paper. The voter then writes in his or her candidate for that office and deposits the write-in vote in a box within the polling station.
A record votes button 22 connected to the embedded processor 12 is also provided within voting machine 10. After a voter has completed his or her selections, he or she may press the record votes button 22 to record the votes and finalize the voting process for that voter. When the voter presses the record votes button 22, the printer 18 prints out a hardcopy of the voter's selections, including any write-in candidates. The voter then takes the hardcopy of his or her votes and places it in a box before leaving the polls. By having a printer 18 print out a hardcopy of the voters' selections, it helps to assure the voter to that his or her votes were successfully recorded and also functions to provide an audit trail of the results. While the record votes button shown in FIG. 1 is an actual button on the voting machine 10, in other embodiments a record votes function may be performed by other operations such as opening a curtain, activating a switch, or pulling a handle.
As shown in FIG. 2, a voting module 14 includes three voting buttons 30 a-30 c and corresponding indicator lights 32 a-32 c. The voting module 14 also includes a power supply 46 (e.g., a lithium battery), which provides back up power to the module in the event of a failure of the main power supply of voting system 10 (shown in FIG. 1).
The voting module 14 also includes a multiplexor/demultiplexor 40 with is connected to each of the voting buttons 30 a-30 c and indicator lights 32 a-32 c. The multiplexor/demultiplexor 40 is also connected to an interconnection device 44 (e.g., a plug). When module 14 is inserted into the voting machine 10, the interconnection device 44 connects with a mating interconnection device (not shown) in voting machine 10 in order to establish a communication channel between module 14 and the embedded processor 12.
When one of the voting buttons 30 a-30 c is selected, the multiplexor/demultiplexor 40 senses which of the three buttons was selected and transmits that information to the embedded processor. As will be described in greater detail below, the embedded processor determines whether the button selected by the voter is a proper selection. If it is, then the embedded processor sends a signal back to the multiplexor/demultiplexor 40 indicating a proper selection and the multiplexor/demultiplexor 40, in turn, illuminates the corresponding indicator light. If the embedded processor determines that the button selected by the voter is not a proper selection, then no signal will be sent to the multiplexor/demultiplexor 40 instructing an illumination of an indicator light.
Like the other components of voting machine 10 (e.g., the display 16, printer 18, electrostatic input device 20), the voting module 14 is a hot-swappable component of the voting machine 10 (shown in FIG. 1). The voting buttons 30 a-30 c and vote selection lights 32 a-32 c are monitored by the embedded processor in order to detect a failure of a voting button or indicator light. After each voter presses the record votes button 22, the embedded processor runs a systems check on each of the voting buttons 30 a-30 c, indicator lights 32 a-32 c, and other components such as the printer, display and write-in mechanism to ensure that the voting machine 10 is functioning properly. If embedded processor 12 detects a failure of a voting button 30 a-30 c, indicator light 32 a-32 c, or other component, the embedded processor 12 prevents further voting until the component containing the failed sub-component is replaced or repaired. If the systems check run by embedded processor 12 indicates that all components are functioning properly, the voting machine 10 permits voting by the next voter.
In a separate embodiment of voting module 14, a separate multiplexor and demultiplexor may be used, the multiplexor dedicated to sensing which buttons have been selected and relaying the information to the embedded processor, and the separate demultiplexor dedicated to receiving control signals from the embedded processor to illuminate indicator lights.
In yet another embodiment of voting module 14, the voting buttons and corresponding indicator lights may be connected directly to the embedded processor over an interconnection device and with a multiplexor/demultiplexor located within embedded processor.
As shown in FIG. 3, the embedded processor 12 of voting machine 10 (shown in FIG. 1) includes a central processing unit (CPU) 60, Read-Only Memory (ROM) 62, Random Access Memory (RAM) 64, a power supply 66, a back up power supply 68, a Universal Asynchronous Receiver Transmitter (UART) 70, and an input/output device 72 interconnected across a bus 74. Embedded processor 12 is fully encapsulated in a tamper-resistant package, such as a molded plastic case that surrounds the embedded processor.
As will be explained in greater detail below, the ROM 62 contains the set-up routine which may be part of the operating system of the voting machine or may be a separate program. The set-up routine is used by officials use to set-up the parameters of the particular election before the election and validates and records the voter's selections during the voting process. ROM 62 also contains driver information for the peripheral devices (e.g., the display 16, printer 18, voting modules 14, electrostatic input device 22 and record votes button 22) of the voting machine 10. While ROM 62 contains the set-up program, RAM 64 stores the parameters selected by the voting officials through the set-up program before the election. RAM 64 is interconnected to the CPU 60 via a separate memory bus 75.
While ROM 62 and RAM 64 are illustrated in FIG. 3 as storage devices for the embedded processor, many other storage devices may be used in lieu of or in addition to ROM 62 or RAM 64, such as a hard-drive, floppy disk drive, removable disk drive, Electronically Programmable Read Only Memory device (EPROM), an Erasable Electronically Programmable Read Only Memory device (EEPROM), or one or more registers.
Power supply 66 is an AC-DC converter which plugs into an AC power source 76 (e.g., a wall socket) and delivers DC power to the embedded processor and the peripherals of the voting machine (i.e., the voting modules, the printer, and the display). Backup power supply 68 is a lithium battery located within embedded processor 12 which provides DC power in the event of a power failure of power supply 66. In another embodiment, a backup power supply may be located wholly or partially outside the embedded processor. Additionally, other embodiments may include additional back up power supplies, such as a car battery, a fuel cell, or a gas-powered generator to provide longer-term backup power in the event of a power outage.
UART 70 is included within embedded processor 12 and connects to an election control panel 71. Vote tallies are downloaded from the voting machine 10 to the election control panel 71 via UART 70 after each voter completes his or her ballot. The election control panel includes a storage device which stores the vote totals. This permits voting officials to monitor the election results on a real-time basis. In addition, storing the vote totals on the election control panel provides a back-up storage system for the vote totals. Thus, if RAM 64 of the voting machine 10 should become erased or corrupted during the voting process, vote totals for the voting machine would still be preserved.
In addition to downloading vote totals to an election control panel 71, UART 70 may also upload information from the election control panel 71 to the voting machine 10 during the election. For example, voting officials may upload voter information such as political party registration and voting restrictions via the UART 70. This voter information may be used by embedded processor 12 to validate voter selections. Additionally, if embedded processor 12 should fail during the election, voting officials may replace it with a functional embedded processor. Rather than setting up the new embedded processor, voting officials may upload set up information and vote totals that had been saved from the previous embedded processor via the UART 70. This permits voting officials to quickly and easily replace a faulty embedded processor during the election.
The election control panel 71 may include a public counter, which may be viewed by election officials during the election, as well as a protected counter which cannot be accessed without a password. Additionally, the election control panel 71 may include the capability to electronically lock and unlock voting machine 10 at the beginning and end of the voting period.
Embedded processor 12 is also connected to printer 16, display 18, the electrostatic input device 20, and the record votes button 22. All of these components (i.e., the printer 16, display 18, electrostatic input device 20, and record votes button 22) are hot-swappable components that may be replaced during an election should one or more fail.
In another embodiment, the voting machine 10 may include a second embedded processor in order to eliminate some of the computational burden on a single CPU. For example, a second processor may be used to perform print driving functions, and refresh for the selection indications.
The voting machine 10 is configured for a particular election through a set-up program stored in ROM 62. Voting officials use the set up routine configure each candidate space location according to information on the printed ballot card for a particular election. Once the set-up information is loaded, it may be used to validate voter's selections and record the votes.
Embedded processor 12 associates a number of bits at a permanent address location within RAM 64 (shown in FIG. 3) for each candidate space location within the voting machine 10. Voting officials configure the candidate space locations by enabling various bits that are assigned to each candidate space location.
As shown in FIG. 4, a block of sixty (60) bits of RAM 64 is assigned to each candidate space location (e.g., “Candidate Space Location A” shown in FIG. 1) in a voting machine. These blocks of sixty bits are used to store the set up information input by voting officials, the choices voters make during the voting process, and the accumulated vote totals for each candidate space location. In this embodiment, the block of sixty bits for each candidate location is assigned the definitions shown in Table I.
0 Office Enable Bit (OF) Indicates whether the candidate space location is the start of
an office or question field on the printed ballot card. All of
the candidate space locations associated with a particular
office or question on the printed ballot card are defined as a
candidate field or, in the case of a question, a question field.
1 Candidate Enable bit Indicates whether the candidate space location is associated
(CE) with a candidate on the printed ballot card. If this bit is set,
then the voting button and indicator light associated with this
candidate space location will be active during the voting
2 Write-In Enable bit Indicates whether the candidate space location is associated
(WI) with a selection to write in a candidate.
3 Vote Enable bit (V) Indicates whether the candidate space location has been
selected by the voter.
4 Question Enable bit Indicates whether the candidate space location is associated
(Q) with a response to a question presented to a voter (e.g., “yes”
or “no”). If this bit is set, then the voting button and
indicator light associated with this candidate space location
will be active during the voting process.
5 Slate Enable bit (SE) Indicates whether the candidate space location is associated
with a vote for an entire slate of candidates. For example,
this feature may be used to permit a voter to press a single
button to automatically select all democratic or republican
candidates for all offices having a democratic or republican
6 Primary Enable bit Indicates whether the candidate space location is associated
(PE) with a primary election where only a portion of the
candidates presented can be selected at any one time. For
example, in a primary election registered democrats may only
vote for democratic candidates and registered republicans
may vote for republican candidates. In many states
independents may choose a party in secret in the booth, but
then are locked out from the other parties.
7 Endorsed Candidate Indicates whether the candidate space location is associated
Enable bit (ECE) with a selection for one or more endorsed candidate. For
example, this feature may be used to permit a voter to press a
single button to automatically select all candidates who have
received a particular endorsement with one button or switch.
8 Restricted office bit Indicates whether the candidate space location is associated
(ROF) with a restricted office election in a particular election. For
example, a restricted office election may happen when a
voter lives in a school district but outside a municipality; this
voter may be able to vote for school committee candidates,
but may not vote for municipal offices.
9 Restricted Question bit Indicates whether the candidate space location is associated
(RQ) with a restricted question in a particular election. For
example, a restricted question may happen when a voter is
able to vote on a particular question or issue, e.g., a school
bond issue, but not for candidates for office.
10 Disable Restricted Prohibits the setting of any restricted questions in a particular
Question bit (DRQ) election.
11 Disable Restricted Prohibits the setting of any restricted offices in a particular
Office bit (DROF) election.
12 Disable Endorsed Prohibits the setting of any endorsed candidates in a
Candidate bit (DECC) particular election.
13-20 Number of Votes For Indicates the maximum number of candidates a voter may
byte (VF) select for a particular office or question field. For example, if
the voter may only vote for one candidate for the particular
office, then these bits may be set to 0000 0001. If the voter
may vote for two candidates for a particular office, then the
bits may be set to 0000 0010.
21-28 Slate Identifier byte This byte associates the candidate location space with a
particular slate of candidates. For example, a 0000 0001 in
this location may indicate the candidate is a Republican, a
0000 00010 may indicate a Democrat, a 0000 00011 may
indicate Libertarian, and so on. If the slate enable bit is
enabled, a voter may be able to vote for all Republicans,
Democrats, Libertarians, etc. in each office up for election by
selecting a single switch or button.
29-36 Primary Identifier byte This byte associates the candidate space location with a
particular political party that has candidates running against
each other in a primary election. If the primary enable bit is
enabled, a voter is restricted to vote for only candidates
associated with the voter's registered political party. Or, in
some states, independent voters may choose which political
party primary to participate in while in the voting booth, but
becomes blocked out of other party's primaries once the
voters makes a selection.
37-44 Endorsed Candidate This byte associates the candidate space location with a
Identifier byte particular endorsement. If the endorsed candidate enable bit
is enabled, the candidate space location is linked to one or
more other candidates on the ballot by assigning each of the
candidates the same value in this byte. A voter may thus
select a group of candidates associated with a particular
endorsement by selecting a single button or switch.
45-60 Number of Candidate These two bytes hold the cumulative count of votes for the
Votes bytes candidate space location during a particular election.
The block of bits illustrated in FIG. 4 and described in Table I permits the voting machine 10 to be adapted to different requirements of the various states' and countries' voting laws. Various embodiments may include fewer of the set up bits to provide a simpler, but less versatile system, or additional bits to increase versatility.
In addition to storing the set up information for each candidate space location, a portion of RAM 64 is reserved to store voter information such as the voter's political party affiliation (which may be used to restrict the voter's ability to vote for candidates associated with other political parties in a primary election) or voter restrictions (which may be used to restrict the voter to only certain items on the ballot). A voting official enters the voter information externally via an election control panel 71 and uploads it to the voting machine 10 via UART 70. Alternatively, the voting official may enter the voter information through an input device (e.g., the touch-screen display 18) directly connected to embedded processor 12.
A voting official will set the appropriate bits for each candidate space location according to the information on the printed ballot card 26 a-26 b (shown in FIG. 1). In practice, a voting official may insert a printed ballot card into the ballot card holder and then set the appropriate bits for each candidate space location. Voting officials may access to set up routine to set the bits through a variety of interfaces commonly used, including a graphical user interface presented on a touch screen display (as illustrated in FIG. 1) or a display in combination with a keyboard, mouse, trackball, touchpad, or the like either integrated within or external to the voting machine.
To illustrate how a voting official might use this technique, FIG. 5 shows a printed ballot card 28 inserted into a ballot card holder 24 in a voting machine 10. In this embodiment, a voting machine includes a voting module 14 which has fifteen (15) sets of voting buttons 30 a-30 o and corresponding indicator lights 32 a-32 o. The fifteen buttons and indicator lights provided on voting module 14 signify fifteen candidate space locations labeled A-O. Each candidate space location A-O is assigned a block of sixty (60) bits in RAM within the embedded processor of the voting machine. The blocks of sixty bits assigned to each candidate space location are defined in accordance with FIG. 4 and Table I.
The printed ballot card 26 contains two issues for a voters' consideration. First, voters may select two candidates for a local school board election and second, voters may vote on whether or not to raise a levy on real property taxes. Additionally, the printed ballot card permits voters to select all of the Democratic or Republican party candidates running for office with a single selection. Prior to the election, a voting official would place the printed ballot card 26 into the ballot card holder 24 on the voting machine 10 and then, through a graphical user interface, set the bits shown in Table II for each candidate space location.

Once the bits are set, the printed ballot card should be sealed within the ballot card holder in order to prevent removal of the printed ballot card until after the voting is completed. As described below, the embedded processor uses these set up bits during the election in order to validate selections, prevent an over-vote, and control the voting process.
In operation, a voter enters a voting station containing a set up voting machine with a printed ballot card sealed in place. When the voter makes a selection by pressing one of the voting buttons, the multiplexor/demultiplexor 40 a (shown in FIG. 2) relays the information to the embedded processor. The set up routine stored on ROM 62 verifies that the button selected by the voter is a proper selection according to the algorithm illustrated in FIG. 6.
As shown in FIG. 6, when the embedded processor receives a signal indicating that a button has been pressed (90), the embedded processor then first checks the bits associated with the candidate space location of the button which was pressed to ensure that the button is within an active candidate space location (92). To do this, the embedded processor checks to ensure that either the CE (candidate enable bit) or Q (question enable) bit is enabled. If neither of these bits is enabled, then the button that the voter has pressed is not associated with an active candidate space location and the embedded processor will not illuminate the indicator light (94).
If either the CE or Q bit is enabled, then the embedded processor will then check to see if the button has previously been selection by the voter by reading the V bit (96). If the bit is a “1”, then the button has been previously pushed by the voter and the embedded processor will deselect the button by writing a “0” to the V bit for that candidate location space and extinguishing the indicator light (98). If the V bit is a “0”, then the embedded processor will proceed to run a number of checks on the other candidate space locations within the candidate or question field in which the selection was made. The candidate or question field is the group of candidate space locations which correspond to an office up for election on the ballot card or a question posed to the voters on the ballot card. For example, referring to FIG. 5, the candidate or question fields are A-E (vote for all democratic or republican candidates), G-K (vote for school board members), and L-O (vote on property tax).
The embedded processor will next check to see if the election is a primary by checking the PE bit in the candidate space location of the button that was selected (100). If the PE bit is enabled, then it is a primary election and voters registered with a political party may only vote in their party's primary election. The embedded processor will check the voters' political party (which is entered by voting officials) against the primary byte in the candidate space location to see if they match (101). If they do not match, then the selection is improper and the indicator light is not illuminated and a “1” is not written to the V bit (94). If they do match, then the embedded processor runs additional checks to see if the selection is valid. In other embodiments the embedded processor may be programmed to permit independent voters to participate in a primary election. In this embodiment, the embedded processor would read the political party of the candidate which the voter makes his or her selection and then locks to voter into the primary election for that political party and prevents the voter from making any selections from a different party.
After running the primary election check (100), if either the election is not a primary election or the election is a primary election and the voter is permitted to vote for the candidate selected, the embedded processor then checks to see if this is a restricted candidate or question (102). The embedded processor reads the ROF, RQ, DRQ and DROF bits of the candidate space location of the button that was selected to determine if the field is restricted. If it is (i.e., ROF=1 and DROF=0, or RQ=1 and DRQ=0), then the embedded processor checks to see if the voter is permitted to vote for the restricted candidate or question (104). If the voter is not able to vote for the restricted candidate or question, then the selection is not proper and the embedded processor does not illuminate a indicator light or write a “1” to the V bit (94).
If either the candidate or question field is not a restricted candidate or question or if it is restricted but the voter is allowed to vote in the restricted question or candidate field, then the embedded processor checks to see is the button selected is associated with a slate of candidates by reading the SE bit of the candidate space location of the button that was selected (108). If the SE bit is enabled, the embedded processor runs a slate selection routine (110) to automatically select all candidates matching the slate identifier of the button which was selected by the voter. The slate selection routine (110) checks to ensure that each of the votes on the slate is a valid selection and then will select all valid selections on the slate.
If the SE bit is not enabled, then the button selected by the voter is not associated with a vote for a slate of candidates and the processor moves on to check whether the button selected is associated with a vote for an endorsed candidate (112). The embedded processor checks the ECE bit in the candidate space location of the button that was selected to see if the button pressed by the voter is associated with an endorsement vote. If the ECE bit is enabled then the embedded processor runs an endorsed candidate selection routine (114) to automatically select all candidates matching the endorsed candidate identifier. The endorsed candidate selection routine (114) will check to ensure that each of the selections for the endorsed candidates is a valid selection and then will select all valid selections within the group of endorsed candidates.
If the ECE is not enabled, then the button selected by the voter is not associated with a vote for one or more endorsed candidates, and the embedded processor continues to validate the voter's selection by checking to see if the maximum number of votes have been received in the candidate or question field (114). The embedded processor reads the VF byte in the first candidate space location in the candidate or question field in which the voter pressed the button to see the maximum number of votes the voter may cast for this particular office or question in the election. The embedded processor then reads the V bit in each of the active candidate space locations in the candidate or question field (i.e., those candidate space locations in the field which have either the CE or Q bit enabled). The embedded processor counts the number of V bits that have been enabled in each of the active candidate space locations in the candidate or question field and compares the total to the value of the VF byte at the first candidate space location in the field. If the total number of V bits set to “1” in the active candidate space locations in the field is less than VF, then the maximum number of votes has not been received and the embedded processor then moves on to check to see if the button selected by the voter is associated with a write-in candidate (116).
If, however, the total number of V bits in the active candidate space locations in the candidate or question field is not less than VF, then the maximum number of votes has been received. In this case, the embedded processor will then check to see if the voter is only able to select one candidate or response to a question in the candidate or question field by to see if the value of the VF byte is set to one (i.e., VF=0000 0001) (118). If it is, then the embedded processor will deselect the other previous button pressed by the voter in the candidate or question field (120). The embedded processor deselects a button by extinguishing the indicator light associated with the button and writing a “0” to the V bit in the candidate space location associated with the button. After deselecting the previous button (120), the embedded processor then checks to see if the current button selected is associated with a write-in candidate (116). If the embedded processor determines that the maximum number of selections a voter may make in a candidate or question field is greater than one and the maximum number of selections has already been made by the voter prior to pressing the current button, then the voter's selection is an improper selection and the embedded processor will not select or deselect any buttons (94).
If the maximum number of votes has not been received (or if the maximum number ahs been received and the embedded processor has deselected the previously-selected button (120)), then the embedded processor checks the WI bit of the candidate space location associated with the button selected by the voter (116). If the bit is set to “1”, then the embedded processor illuminates the indicator light associated with the button, writes a “1” to the V bit in the candidate space location associated with the button, and records the voter's write in vote on the electrostatic write-in device (122). If the WI bit is set to “0”, then the embedded processor illuminates the indicator light associated with the button and writes a “1” to the V bit in the candidate space location associated with the button (124).
After the voter has completed making his or her selections, the voter finalizes the voting process by pressing the record votes button 22 (shown in FIG. 1). When the voter presses this button, the embedded processor reads all of the V bits in the active candidate space locations (i.e., those candidate space locations which have a CE or Q bit enabled). For each “1” read in the V bit location, the embedded processor will add a one to the bytes containing the total number of votes received for that candidate space location (shown in FIG. 4) and then rewrite a “0” in the V bit location. After recording the votes, the embedded processor then downloads the vote count to an external device (e.g. election control panel 71) maintained by the election officials via the UART 70 (shown in FIG. 3). The embedded processor also runs a systems check after each voter to ensure that all components (e.g., voting modules, printer, display, electrostatic input device) and sub-components (e.g., buttons and indicator lights) are functioning properly. If they systems check indicates that all components and sub-components are functioning properly, the voting machine is ready for the next voter. If the systems check reveals a faulty component or sub-component, this information is relayed to the election control panel and the voting machine prevents further voting until the problem is fixed.
As shown in FIG. 7, another embodiment of voting machine 10 includes a surface 130 having an electrostatic point embedded in each candidate space location 132 a-132 k. A printed ballot card (not shown) may be placed on top of the surface 130 and the electrostatic points 132 a-132 k. The surface 130 of the voting machine 10 includes four pegs 134 a-134 d which match with four corresponding holes on the printed ballot card in order to ensure that the printed ballot card is properly aligned when it is placed on the surface 130 of the voting machine 10. A clip 136 mounted to the voting machine further secures the printed ballot card in place.
Once the printed ballot card secured in placed on top of the surface 130 of the voting machine 10, the voter uses a pen to mark the ballot. As the voter marks the ballot the electrostatic points on the surface 132 a-132 k of the voting machine 10 sense the voter's mark on the ballot and record the vote. A voter may write-in a candidate by marking by marking a space on the printed ballot card that indicates a desire to write-in a vote. The electrostatic point aligned with this point is set up to tell the embedded processor that a write in vote is being entered for the particular office. The voter then writes in his or her vote on a piece of paper or via an electronic input device (e.g., a keyboard, electrostatic input device, touch screen).
