RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 16/719,416, filed on Dec. 18, 2019, which claims priority to U.S. Provisional Patent Application No. 62/834,724, filed on Apr. 16, 2019, the entire contents of which are incorporated herein by reference. 
    
    
     FIELD 
     This application relates to geofence tracking for power tool devices and corresponding graphical user interfaces displayed on a mobile communications device. 
     SUMMARY 
     User interfaces of tracking systems for large inventories can be cumbersome and complicated, leading to frustrating and inefficient user experiences that require multiple user steps to gather desired information, which slows adoption and usage of such systems. Further, tracking systems designed for generic inventory, rather than particularly for power tool devices, lack features and functionality particularly helpful in the power tool industry context. Embodiments described herein provide, among other things, power tool tracking systems, methods and related user interfaces, with improved usability through efficient tracking data aggregation, analysis, and presentation. For example, in some embodiments, tracking data is analyzed to determine multiple tool tracking statistics and simultaneously displayed on a single dashboard along with identifying information and configuration options. 
     One embodiment provides a mobile communications device for power tool geofence tracking. The mobile communications device includes a transceiver configured to enable communications between the mobile communications device and one or more power tool devices. The mobile communications device also includes an electronic display and an electronic processor communicatively coupled to the transceiver and the electronic display. The electronic processor is configured to determine a location of the one or more power tool devices and generate a dashboard. The dashboard simultaneously displays an identity and location associated with a tool inventory and a link to a geofence boundary setup screen. The geofence boundary setup screen is configured to define a geofence boundary for the tool inventory. The dashboard also simultaneously displays inventory data of the tool inventory including an indication of a number of missing tools, a number of tools with suggested service, a number of tools missing for a specified period of time, and a number of tools outside of the geofence. The dashboard also simultaneously display a link to conduct a wireless inventory audit for the inventory. The electronic processor is also configured to display, on the electronic display, the dashboard. 
     Another embodiment provides a method for power tool geofence tracking and dashboard display. The method includes determining, using an electronic processor with a transceiver, a location of one or more power tool devices and generating, using the electronic processor, a dashboard to simultaneously display a location-based inventory, indication of number of missing tool, and geofence boundary setup of power tool devices within the inventory. The method also includes displaying, using the electronic processor, the dashboard on an electronic display. 
     Another embodiment provides a mobile communications device for power tool geofence tracking. The mobile communications device includes a transceiver configured to enable communications between the mobile communications device and one or more power tool devices and an electronic display. The mobile communications device also includes an electronic processor communicatively coupled to the transceiver and the electronic display. The electronic processor is configured to determine a location of the one or more power tool devices and generate a dashboard. The dashboard simultaneously displays an identity and location associated with a tool inventory and a link to a geofence boundary setup screen. The geofence boundary setup screen is configured to define a geofence boundary for the tool inventory. The dashboard also simultaneously displays a link to conduct a wireless inventory audit for the inventory. The mobile communications device is also configured to display, on the electronic display, the dashboard. 
     Another embodiment provides a remote server configured to populate a geofence boundary with a first plurality of reference points and populate an area around one or more power tools with a second plurality of reference points. The remote server is also configured to run the first plurality of reference points and the second plurality of reference points through a clustering function and determine whether one or more of the second plurality of reference points is in a same cluster as one or more of the first plurality of reference points. The remote server is further configured to determine that the one or more power tools is within the geofence boundary when one or more of the second plurality of reference points is in the same cluster as one or more of the first plurality of reference points. 
     In some embodiments of the system, the remote server is further configured to determine that the one or more power tools is outside the geofence boundary based on determining that no cluster includes both at least one of the second plurality of reference points and at least one of the first plurality of reference points. 
     In some embodiments of the system, the remote server is configured to transmit an indication indicative of whether the one or more power tools is within the geofence. 
     Another embodiment provides a method for determining whether a power tool is within a geofence boundary. The method includes populating the modified geofence boundary with a first plurality of reference points and populating area around the one or more power tools with a second plurality of reference points. The method also includes running the first plurality of reference points and the second plurality of reference points through a clustering function and determining whether one or more of the second plurality of reference points is in a same cluster as one or more of the first plurality of reference points. The method further includes determining that the one or more power tools device is within the modified geofence boundary when one or more of the second plurality of reference points is in the same cluster as one or more of the first plurality of reference points. 
     In some embodiments of the method, the remote server determines that the one or more power tools is outside the geofence boundary based on determining that no cluster includes both at least one of the second plurality of reference points and at least one of the first plurality of reference points. 
     In some embodiments of the method, the remote server transmits an indication indicative of whether the one or more power tools is within the geofence.

The invention is capable of other embodiments and of being practiced or of being carried out in various ways. 
     It should be noted that a plurality of hardware and software based devices, as well as a plurality of different structural components may be utilized to implement the invention. Furthermore, and as described in subsequent paragraphs, the specific configurations illustrated in the drawings are intended to exemplify embodiments of the invention and that other alternative configurations are possible. The terms “processor” “central processing unit” and “CPU” are interchangeable unless otherwise stated. Where the terms “processor” or “central processing unit” or “CPU” are used as identifying a unit performing specific functions, it should be understood that, unless otherwise stated, those functions can be carried out by a single processor, or multiple processors arranged in any form, including parallel processors, serial processors, tandem processors, or cloud processing/cloud computing configurations. 
       FIG.  1    illustrates a power tool geofence tracking system  100  in accordance with some embodiments. In the example illustrated, the power tool geofence tracking system  100  includes a plurality of mobile communications devices  110 , a plurality of power tool devices  120 , and a remote server  130 . The plurality of mobile communications devices  110  may be singularly referred to as a mobile communications device  110  or one or more mobile communications devices  110 . In the example illustrated, the plurality of mobile communications devices  110  includes a first mobile communications device  110 A and a second mobile communications device  110 B. The plurality of power tool devices  120  may be singularly referred to as a power tool device  120  or one or more power tool devices  120 . 
     Each mobile communications device  110  communicates with one or more power tool devices  120  that are located within a wireless communication range of the mobile communications device  110 . The power tool geofence tracking system  100  is used to track locations of the plurality of power tool devices  120  of a user or an organization. For example, the first mobile communications device  110 A communicates with a first one or more power tool devices  120  within a first location  140  to track the first one or more power tool devices  120 . The first location  140  is for example, a worksite location, a foreman&#39;s office location, or the like. Similarly, the second mobile communications device  110 B communication with a second one or more power tool devices  120  within a second location  150  to track the second one or more power tool devices  120 . The second location  150  is for example, a second worksite location, another office location, or the like. Accordingly, the plurality of mobile communications devices  110  can be used to track the plurality of power tool devices  120  across multiple locations. The power tool geofence tracking system  100  may include more or fewer components than those illustrated in  FIG.  1    and may perform functions other than those described herein. 
     The mobile communications device  110  is, for example, a smart telephone, a tablet computer, a smart watch, a personal digital assistant and the like. The power tool device  120  is any motorized or non-motorized power tool device, for example, a drill-driver, a hammer drill, a rotary hammer, a miter saw, a jigsaw, a work light, a work radio, a dust extractor, ruggedized tracking device (e.g., for securing to construction equipment or materials), and the like, or a power tool battery pack configured to power a power tool device, such as the aforementioned power tool devices. The plurality of mobile communications devices  110  communicate with the plurality of power tool devices  120  over a wireless connection  160 , for example, a Bluetooth® or ZigBee® connection. 
     The plurality of mobile communications devices  110  also communicate with a remote server  130  over a communication network  170 . In some embodiments, the communication network  170  may be an Internet network, a cellular network, another network, or a combination thereof. The mobile communications device  110  can forward to the remote server  130  at least some of the information received from the power tool devices  120 . The remote server  130  provides additional storage and processing power and thereby enables the geofence tracking system  100  to encompass more power tool devices  120  without being limited to the storage and processing capabilities of the mobile communications device  110 . 
     In some embodiments, the plurality of mobile communications devices  110  are issued by a single organization or entity to track the power tool devices  120  that belong to the organization or entity. In some embodiments, each user within an organization or entity has their own power tool devices  120  that can be tracked by one or more mobile communications devices  110 . In other embodiments, a single mobile communications device  110  may be used to track inventory of a single user. In further embodiments, one or more of the plurality of mobile communications devices  110  are owned and operated by independent users. 
     The power tool devices  120  can be added to an inventory using the mobile communications device  110 . For example, a user can use the mobile communications device  110  to pair with a nearby power tool device  120 . Once the mobile communications device  110  receives identification information of the power tool device  120 , the user may add the power tool device  120  to the inventory of the user or the organization. Power tool devices  120  can also be manually added to the inventory by entering identification information of the power tool devices into the mobile communications device  110  or another external electrical device in communication with the remote server  130 . The inventory for each user or organization may be stored in a memory of the remote server  130 , in the mobile communications devices  110 , or both. The inventory may include, for example, one or more of a list of power tool devices (e.g., identified by a serial number or another identification label), an associated user(s), an associated organization(s), a power tool type, an assigned worksite or location, collectively, inventory data. 
       FIG.  2    is a block diagram of one example embodiment of the mobile communications device  110 . In the example illustrated, the mobile communications device  110  includes an electronic processor  210 , a memory  220 , a transceiver  230 , and a user interface  240 . The electronic processor  210 , the memory  220 , the transceiver  230 , and the user interface  240  communicate over one or more control and/or data buses (for example, a communication bus  250 ). The memory  220  includes read only memory (ROM), random access memory (RAM), other non-transitory computer-readable media, or a combination thereof. The electronic processor  210  is configured to communicate with the memory  220  to store data and retrieve stored data. The electronic processor  210  is configured to receive instructions and data from the memory  220  and execute, among other things, the instructions. In particular, the electronic processor  210  executes instructions stored in the memory  220  to perform the methods described herein. 
     The transceiver  230  facilitates communication between the mobile communications device  110  and the power tool devices  120 , between the mobile communications device  110  and the communication network  170 , or both. The mobile communications device  110  communicates with the remote server  130  over the communication network  170  via the transceiver. For example, the transceiver  230  may include a short-range transceiver to facilitate communication with the power tool devices  120  over a Bluetooth® connection and a long-range transceiver to facilitate communication with the communication network  170  over a Wi-Fi™ or a Cellular connection. In some embodiments, the transceiver  230  of the mobile communications device  110  may include separate transmission and receiving components, for example, a transmitter and a receiver, rather than a joint transmitter-receiver. 
     The user interface  240  includes one or more input components and one or more output components. Particularly, the user interface  240  includes an electronic display  260  to display information regarding the power tool devices  120  to a user of the mobile communications device  110 . The electronic display  260  is, for example, a touch screen display that can serve as both an input and an output component. In some embodiments, the user interface  240  includes further inputs (e.g., buttons, switches, dials) and outputs (e.g., a tactile output generator, speaker, etc.). 
     In some embodiments, the remote server  130  (see  FIG.  1   ) has a similar configuration as the mobile communications device  110  shown in  FIG.  2    including an electronic processor, memory, and transceiver coupled by a communication bus, and, in some embodiments, a user interface. Additionally, the memory of the remote server  130  stores data and instructions and the electronic processor of the remote server  130  is configured to receive instructions and data from the memory  220  and execute, among other things, the instructions to perform the functions of the remote server  130  described herein. Further, the remote server  130  may include a single server or a plurality of servers, whether co-located or distributed. 
       FIG.  3    is a block diagram of one example embodiment of the power tool device  120 . In the example illustrated, the power tool device  120  includes a device electronic processor  310 , a device memory  320 , and a device transceiver  330 . The device electronic processor  310 , the device memory  320 , and the device transceiver  330  communicate over one or more control and/or data buses (for example, a device communication bus  340 ). The device electronic processor  310 , the device memory  320 , and the device transceiver  330  are implemented similar to the electronic processor  210 , the memory  220 , and the transceiver  230  respectively. In one example, the device electronic processor  310  and the device memory  320  are part of a microcontroller unit of a motorized or non-motorized power tool or battery pack. In some embodiments, the power tool device  120  also optionally includes additional electronic components  350 . For a motorized power tool (e.g., drill-driver, saw, and the like), the electronic components  350  include, for example, one or more of a power source, an inverter bridge, a motor (e.g., brushed or brushless), and the like. For a battery pack, the electronic components  350  include, for example, one or more of battery cells, a charge level fuel gauge, analog front ends, sensors, and the like. For a non-motorized power tool (e.g., a work light, a work radio, ruggedized tracking device, and the like), the electronic components include, for example, one or more of a lighting element (e.g., an LED), an audio element (e.g., a speaker), a power source, and the like. In some embodiments, the device transceiver  330  is within a separate housing along with another electronic processor and memory, and that separate housing selectively attaches to the power tool device  120 , on an outside surface of the power tool device  120  or by being inserted into a receptacle of the power tool device  120 . Accordingly, the wireless communication capabilities of the power tool device  120  may reside in part on a selectively attachable communication device, rather than integrated into the power tool device  120 . Such selectively attachable communication devices may include electrical terminals that engage with reciprocal electrical terminals of the power tool device  120  to enable communication between the respective devices and enable the power tool device  120  to provide power to the selectively attachable communication device. 
       FIG.  4    is a flowchart of an example method  400  for power tool geofence tracking and dashboard display. In the example illustrated, the method  400  includes determining, using the electronic processor  210  with the transceiver  230 , a location of one or more power tool devices  120  (at block  410 ). The mobile communications device  110  communicates with power tool devices  120  within a wireless communication range of the mobile communications device  110 . The mobile communications device  110  communications with the power tool devices  120  over, for example, a Bluetooth® connection, a ZigBee™ connection, and the like. In one example, the mobile communications device  110  provides a wireless advertisement. The power tool devices  120  that are within the wireless communication range of the mobile communications device  110  and that receive the wireless advertisement establish a connection with the mobile communications device  110  via the device transceiver  330 . Particularly, the power tool devices  120  transmit identification information of the power tool devices  120  to the mobile communications device  110  in response to the wireless advertisement. In some embodiments, additionally or alternatively, the power tool devices  120  periodically transmit a beacon signal (including the identification information) via the device transceiver  330  based on an internal trigger, such as the elapsing of a timer, an internal schedule, sensed movement, or the like. 
     The mobile communications device  110  also receives location information over the communication network  170 . For example, the mobile communications device  110  may include a separate global positioning system (GPS) receiver that determines a location based on signals received from one or more GPS satellites and provides the location to the electronic processor  210 . The mobile communications device  110  then tags the location information to the identification information received from the power tool devices  120 . That is, the mobile communications device  110  stores the identification information from the power tool device  120  along with the location information determined around the same time as when the mobile communications device  110  receives the identification information. The mobile communications device  110  forwards the identification information of the power tool devices  120  and the location information to the remote server  130  over the communication network  170 . The remote server  130  may store the location information as the last seen location of the power tool device  120  to which the location information is tagged. 
     Referring to  FIG.  1   , in one example, the first mobile communications device  110 A outputs a wireless advertisement. The first plurality of power tool devices  120  within the first location  140  provide respective identification information to the first mobile communications device  110 A in response to the wireless advertisement (or internal trigger). The first mobile communications device  110 A determines the location information of the first location  140  from the GPS signal received from the GPS satellite. The first mobile communications device  110 A stores the location information of the first location  140  as the current location of the first plurality of power tool devices  120 . The first mobile communications device  110 A may also forward the current location of the first plurality of power tool devices  120  along with the identification information of the first plurality of power tool devices  120  for storage in the remote server  130  as the last seen location. 
     In some embodiments, one or more of the power tool devices  120  includes a GPS receiver for determining its own location independent of the mobile communications devices  110 , and a long range wireless transceiver to, independent of the mobile communications devices  110 , communicate the identification information along with the determined location information to the remote server  130  for storage as the last seen location. In some embodiments, the GPS receiver and long range wireless transceiver are within a separate housing that selectively attaches to the power tool device  120 , on an outside surface of the power tool device  120  or by being inserted into a receptacle of the power tool device  120 . 
     Accordingly, in some instances, the mobile communications devices  110  are configured to determine a location of one or more power tool devices  120  via direct interfacing with the power tool devices  120 , as explained above. In some instances, the mobile communications devices  110  are configured to determine a location of one or more of the power tool devices  120  via communication with the remote server  130 . For example, the mobile communications devices  110  is configured to query the remote server  130  for location information for one or more of the power tool devices  120  stored on the remote server  130  (e.g., aggregated from other mobile communications devices  110 ). Thus, in one example, the mobile communications device  110 A is configured to determine the location information for power tool devices  120  in the second location  150  from the remote server  130 , which was previously provided to the remote server  130  by the mobile communications device  110 B or directly from the power tool device  120 . 
     Returning to  FIG.  4   , the method  400  also includes generating, using the electronic processor  210 , a dashboard  500  to simultaneously display a location-based inventory, indication of number of missing tools and geofence setup of power tool devices within the inventory (at block  420 ).  FIG.  5    illustrates one example embodiment of the dashboard  500 . The dashboard  500 , as well as other dashboards described below, is generated by execution of a smart phone application, a tablet application, and the like (referred to as a mobile application) for display on the mobile communications device  110  as part of a graphical user interface of the mobile application. In the example illustrated, the dashboard  500  includes a location information section  510 , a location address section  520 , a tool stats section  530 , and an inventory section  540  (that is, location-based inventory). The location information section  510  includes information regarding a specific location, for example, the first location  140 , the second location  150 , and the like. 
     An organizational user can add and configure locations on the mobile communications device  110  using an application executed by the mobile communications device  110 .  FIG.  6    illustrates a second dashboard  600  generated by the electronic processor  210 . The second dashboard  600  is generated in response to receipt of a user request to launch the mobile application and a selection of a places option  610 . The user may use the second dashboard  600  to add and configure locations. For example, the organization user can setup each worksite of one or more projects of the organization. For example, the electronic processor  210  characterizes a location in response to receipt of user input indicating a name  512 , a phone number  514 , a job number  516 , and a division  518  for the location as shown in  FIG.  5   . The user may also provide an address for the location, an image to be used as an icon for the location, and a date range for the job at the location. The name  512 , phone number  514 , cost code  516 , and the division  518  for the location are displayed in the location information section of the dashboard  500 . The location address is displayed in the location address section  520  of the dashboard  500 . An individual user may similarly add location(s), for example, a home location using the mobile application. In response to receipt of a user selection of one of the locations registered in the mobile application, the electronic processor  210  generates and displays the dashboard  500 . 
     When the locations are setup in the mobile application, the user can add and/or assign power tool devices  120  to each location. Particularly, the user may add nearby power tool devices  120  to the user&#39;s inventory and assign the nearby power tool devices  120  to the current location. The power tool devices  120  assigned to the current location may be viewed by selecting an assigned items selection  542  in the inventory section  540 .  FIG.  7    illustrates a third dashboard  700  generated by the electronic processor  210  that displays the power tool devices  120  assigned to a particular location. Particularly, the third dashboard  700  displays identification information of the power tool devices  120  assigned to the particular location. 
     The user may also assign other users or other mobile communications devices  110  to the current location. The users assigned to the current location can access the tools at the current location. For example, the assigned users may use their mobile communications device  110  to lock and unlock tools at the current location for operation. The users assigned to the current location may be viewed by selecting an assigned people selection  544  in the inventory section  540 . 
     The mobile communications devices  110  forward the location and inventory information for storage on the remote server  130 . The location and inventory information stored on the remote server  130  can be accessed by other mobile communications devices  110  that belong to the organization, as well as by the mobile communications device  110  that forward the location and inventory information at a later time. 
     The tool stats section  530  displays information regarding the power tool devices  120  in the inventory. In the example illustrated, the tool stats section  530  displays number of power tool devices  120  marked as missing  532 , number of power tool devices  120  that need service  534 , number of power tool devices  120  not seen in a particular number of days 536, and a number of power tool devices  120  seen outside a geofence  538 . The user of the mobile application can mark the power tool devices  120  as missing if they cannot be found at any of the locations by navigating through the mobile application graphical user interface. In some embodiments, the one or more mobile communications devices  110  may mark the power tool devices  120  as missing when the mobile communications devices  110  cannot communicate with the power tool devices  120  at any of the registered locations for a certain number of days. 
     The one or more mobile communications devices  110  similarly mark the power tool devices  120  as not seen in a particular number of days when the mobile communications devices  110  have not communicated with the power tool devices  120  for that particular number of days at any of the registered locations. For example, as previously noted, the mobile communications devices  110  transmit to the remote server  130  identification and current location information for power tool devices  120  that the mobile communications devices  110  encounter (i.e., become within wireless communication range), and the remote server  130  stores the received current location information as the last seen location for each power tool device  120 . When the remote server  130  determines that the last seen location for one of the power tool devices  120  occurred more than the particular number of days before the current date (i.e., current date−last seen date&gt;particular number of days), the remote server  130  indicates to the mobile communications device  110  that the power tool device  120  has not been seen for the particular number of days. The mobile communications device  110  then updates (i.e., increments) the not seen in a particular number of days statistic  536  in the tool stats section  530 . When a power tool device  120  previously determined to not have been seen for a particular number of days later comes into wireless communication with one of the mobile communications devices  110 , the mobile communications device  110  sends the identifying information of the power tool device  120  and the current location of the mobile communications device  110  to the remote server  130 . The remote server  130  then updates the last seen location and date for the power tool device  120 , and sends a notification to the mobile communications devices  110  having that power tool device  120  in an associated inventory that the power tool device  120  has been seen. The mobile communications device  110  then updates (i.e., decrements) the not seen in a particular number of days statistic  536  in the tool stats section  530 . In some embodiments, the incrementing and decrementing for the not seen in a particular number of days statistic  536  is performed at the remote server  130 , the statistic is provided to the mobile communications device  110  to update the particular number of days statistic displayed in the tool stats section  530 . 
     In some embodiments, the power tool devices  120  communicate sensor and other data to the mobile communications devices  110 . A power tool device  120  may also communicate that the power tool device  120  needs service. Alternatively, the mobile communications device  110  may determine that the power tool device  120  may need service in response to data received from the power tool device  120  or the remote server  130 . In some embodiments, a user may select a power tool device  120  from the inventory and select an option for service. The mobile communications device  110  then displays the number of power tool devices that need service in the tool stats section  530 . 
     In some embodiments, the user may select a geofence setup option  545  to setup a geofence around the location.  FIG.  8    illustrates a fourth dashboard  800  for setting up a geofence for the current location. As illustrated in  FIG.  8   , a user may set up a boundary around the current location. For example, the mobile communications device may receive an initial location selection via the electronic display  260  (e.g., by dragging and dropping a pin on the illustrated map). The mobile communications device  110  then generates a default geofence boundary that is displayed on the map, and receives user boundary input modifications via the electronic display  260  (e.g., through a user dragging boundary corners or points). Once a geofence is defined, the mobile communications device  110  transmits the geofence definition to the remote server  130 . The remote server  130  associates the geofence with the location and location-based inventory. The remote server  130  further compares the last seen location information for each power tool device  120  of the associated inventory, and determines whether each of the power tool devices  120  is within or outside the geofence. One example method for determining whether a power tool device  120  is within or outside the geofence is explained below with respect to  FIG.  12   . The remote server  130  then transmits the results of the comparison to the mobile communications device  110 , for example, by transmitting an indication of whether each power tool device  120  of the associated inventory was determined to be inside the geofence or outside the geofence. Returning to the dashboard  500  of  FIG.  5   , the tool statistic, seen outside the geofence  538 , is updated to indicate the number of the power tool devices  120  of the associated inventory that are outside of the geofence  538 , determined by the mobile communications device  110  based on the information received from the remote server  130  (e.g., by incrementing and decrementing a counter for each of the power tool devices  120  indicated outside of the geofence and inside the geofence, respectively). 
       FIG.  9    illustrates a fifth dashboard  900  that shows a number of tools found outside the geofence boundary set up by the user of the mobile application. The fifth dashboard  900  is generated by the electronic processor  210  when the user selects the seen outside geofence  538  option in the dashboard  500 . The fifth dashboard  900  displays the identification information of the power tool devices  120  found outside the geofence boundary of the current location. 
       FIG.  10    illustrates a sixth dashboard  1000  that shows an audit of the inventory at the current location. The sixth dashboard  1000  is generated by the electronic processor  210  in response to receipt of a user selection of an audit inventory option  546  on the dashboard  500 . The sixth dashboard  1000  displays identification information of the power tool devices  120  in the inventory that are assigned to the current location. For example, the electronic processor  210  access inventory information stored in the memory  220 , in the remote server  130 , or both, for inclusion in the sixth dashboard  1000 . Further, the electronic processor  210  determines which of the power tool devices  120  in the inventory have been marked as missing (e.g., information obtained from the remote server  130 ), which of the power tool devices  120  in the inventory are outside of the associated geofence (e.g., information obtained from the remote server  130 ) and which of the power tool device  120  in the inventory are outside of communication range with the transceiver  230  of the mobile communications device  110  (e.g., based on a lack of receipt of a signal by the transceiver  230  from the power tool devices  120  for a predetermined time period). The electronic processor  210  may also provide colored indications by the identification information of the power tool devices  120  based on the status of the power tool devices  120 . For example, the electronic processor  210  may provide a first indication (e.g., a green border) by the identification information of the power tool devices  120  that can be found at the current location and do not need service, provide a second indication (e.g., a red border) by the identification information of all power tool devices  120  that need service, and provide a third indication (e.g., a gray border) by the identification information of the power tool devices  120  that are marked as missing, are found outside the geofence boundary of the current location, or are outside of communication range with the mobile communications device  110  on which the inventory audit was initiated. 
     The user of the mobile application may also request a summary of the inventory at the current location by selecting a view summary option  1010  on the sixth dashboard  1000 .  FIG.  11    illustrates a summary dashboard  1100  generated by the electronic processor  210  in response to receipt of a user selection of the view summary option  1010 . The summary dashboard  1100  displays additional tool statistics of the power tool devices  120 . Particularly, the summary dashboard  1100  displays a number of power tool devices  120  in the inventory assigned to the current location and detected at the current location  1110 , a number of power tool devices  120  in the inventory not assigned to the current location and detected at the current location  1120 , and a number of power tool devices  120  in the inventory not detected at the current location  1130 . In some embodiments, the user also has the option to receive periodic summary emails (for example, weekly emails) generated by the remote server  130 . The summary emails may provide the tool statistics of the power tool devices  120 , for example, the number of power tool devices  120  in the inventory assigned to the current location and detected at the current location, the number of power tool devices  120  in the inventory not assigned to the current location and detected at the current location  1120 , and the number of power tool devices  120  in the inventory not detected at the current location  1130 . 
     Returning to  FIG.  4   , the method  400  also includes displaying, using the electronic processor  210 , the dashboard  500  on the electronic display  260  (at block  430 ). The electronic processor  210  causes the dashboards  500 ,  600 ,  700 ,  800 ,  900 ,  1000 ,  1100  to be displayed on the electronic display  260  of the mobile communications device  110 . 
     As discussed above, in some embodiments, the remote server  130  determines whether each power tool device  120  is within or outside a geofence.  FIG.  12    is a flowchart of one example method  1200  for determining a location of a power tool device  120  with respect to a geofence using a clustering technique. In the example illustrated, the method  1200  includes receiving geofence location information (for example, a geofence boundary or a modified geofence boundary) (at block  1210 ). Referring to  FIG.  8   , a user may set up a geofence on the fourth dashboard  800  by using the user interface  240  to manipulate a boundary region on a map. In some embodiments, the geofence may be a continuous area within a boundary or may include two or more areas having separate boundaries.  FIG.  8    illustrates an example of a geofence including a continuous area. In some situations, a user may set up a geofence that includes, for example, two building but excluding the street or area between the two buildings. In these situations, the user may setup a first area by drawing a first border around a first building on the map and may setup a second area by drawing a second border around a second building on the map. Once a geofence is defined, the mobile communications device  110  transmits the geofence definition (i.e., the geofence location information) to the remote server  130 . 
     The method  1200  also includes receiving power tool device  120  location information (at block  1220 ). As explained above with respect to block  410  of  FIG.  4   , the mobile communications device  110  determines a location of the power tool devices  120  and transmits the location of the power tool devices  120  along with the identification information of the power tool devices  120  to the remote server  130 . Additionally, in some embodiments, one or more of the power tool devices  120  includes a GPS receiver for determining its own location independent of the mobile communications devices  110 , and a long range wireless transceiver to, independent of the mobile communications devices  110 , communicate the identification information along with the determined location information to the remote server  130  for storage as the last seen location. The method  1200  also includes populating the geofence location with a first plurality of reference points (at block  1230 ). The remote server  130  populates the area of the geofence location with the first plurality of reference points. For example, referring to  FIG.  13 A , the remote server  130  may begin by plotting the locations of the geofence (e.g., the boundary points  1305 ) and the power tool device  120 .  FIG.  13 B  illustrates the geofence location populated with the first plurality of reference points  1310 . The first plurality of reference points may be placed equidistant from each other within the boundaries of the geofence location. In some embodiments, some of the first plurality of reference points may be provided just outside the boundaries of the geofence location to account or adjust for errors in the received location or the geofence location. The number or density of the first plurality of reference points may be varied based on the accuracy specifications for the system  100 . In some embodiments, the spacing of the first plurality of reference points depends on the size of the geofence location. For example, a large geofence may include more spacing between the first plurality of reference points and a small geofence may include less spacing between the first plurality of reference points. 
     The method  1200  further includes populating an area around the location  1315  of the power tool device  120  with a second plurality of reference points (at block  1240 ). In some embodiments, the remote server  130  populates the area within the location of the power tool device  120  with the second plurality of reference points. In other embodiments, the remote server  130  expands the area of the power tool device  120  location and populates the expanded area with the second plurality of reference points.  FIG.  13 C  and  FIG.  13 D  illustrate the power tool device  120  location populated with the second plurality of reference points  1320   a  and  1320   b , respectively. The area and the number or density of second plurality of reference points may be adjusted based on the accuracy specifications for the system  100 . For example, when the system has higher accuracy specifications, the second plurality of reference points  1320   a  may be compactly grouped near the location  1315  of the power tool device  120 , such as illustrated in  FIG.  13 C . When the system has lower accuracy specifications, the second plurality of reference points may be less compactly grouped near the location  1315 , such as illustrated in  FIG.  13 D . 
     The method  1200  also includes the remote server  130  running the first plurality of reference points and the second plurality of reference points through a clustering function (at block  1250 ). In other words, the clustering function is executed, by the remote server  130 , using the first and second plurality of reference points as inputs to the function. Various clustering functions may be used by the remote server  130 , such as a K-means clustering function, a means-shift clustering algorithm, a density-based spatial clustering of applications with noise (DBSCAN) function, or a hierarchical clustering function. For example, in some embodiments, the clustering function receives a distance value and a plurality of reference points and outputs one or more clusters. Each cluster including a subset of the plurality of reference points. A subset of the plurality of reference points are grouped together into a cluster when each one of the subset of the plurality of reference points is within the distance value away from at least one other of the subset of the plurality of reference points. 
     The method  1200  further includes determining whether at least one of the second plurality of reference points is in a same cluster as one of the first plurality of reference points (at block  1260 ). The remote server  130  may examine each of the one or more clusters output from the clustering function to determine whether at least one of the one or more clusters includes at least one of the first plurality of reference points and at least one of the second plurality of reference points. For example, the remote server  130  may compare the reference points in each cluster to the list of first and second reference points to identify matches to determine whether the clusters include at least one of the first reference points and at least one of the second reference points. 
     When the remote server  130  determines that at least one of the second plurality of reference points is in the same cluster as one of the first plurality of reference points, the method  1200  includes determining that the power tool device  120  is within the geofence location (at block  1270 ). The remote server  130  transmits an indication to the mobile communications device  110  that the power tool device  120  is within the geofence location and the mobile communications device  110  displays that the power tool device  120  is within the geofence location, for example, on the second dashboard  600 . 
     When the remote server  130  determines that no cluster includes both at least one of the second plurality of reference points and at least one of the first plurality of reference points, the method  1200  includes determining, by the remote server  130 , that the power tool device  120  is outside the geofence location (at block  1280 ). The remote server  130  transmits an indication to the mobile communications device  110  that the power tool device  120  is outside of the geofence location and the mobile communications device  110  displays that the power tool device  120  is outside of the geofence location, for example, on the fifth dashboard  900 . 
     In the example of  FIG.  13 C , because the spacing between the first plurality of reference points  1310  and the second plurality of reference points  1320   a  of the power tool device  120  is significant, the clustering function executed using these points as inputs is unlikely to result in at least one cluster having at least one of the first plurality of reference points and at least one of the second plurality of reference points. In such an example, the power tool device  120  would be determined to be outside of the geofence. In the example of  FIG.  13 D , because at least some of the second plurality of reference points  1320   a  overlap with the area of the first plurality of reference points  1310 , the clustering function executed using these points as inputs is likely to result in at least one cluster having at least one of the first plurality of reference points and at least one of the second plurality of reference points. In  FIG.  13 D , an example of a cluster  1325  is illustrated having at least one of the first plurality of reference points and at least one of the second plurality of reference points. In such an example, the power tool device  120  would be determined to be within the geofence. Similar techniques as described in method  1200  may also be used to determine whether any of the power tool devices  120  are within any other geofences defined by the user. In addition, the summary email generated by the remote server  130  described above may also provide information regarding whether any of the power tool devices  120  were found in any geofences defined by the user. 
     Generally, the clustering technique reduces the likelihood of incorrectly determining that the power tool device  120  is outside of the geofence due to location anomalies (e.g., temporarily inaccurate GPS location information for the power tool device  120 ). In other words, the clustering technique can reduce false positives inaccurately indicating that the power tool device  120  is outside of the geofence. 
     In some embodiments, the requirement for the number of first reference points and the number of second references points to be present in the same cluster to determine that the power tool device  120  is within the geofence may be varied based on the accuracy specifications of the system  100 . For example, based on the accuracy specifications, the remote server  130  may looks for at least one of the second plurality of reference points to be in the same cluster as at least four of the first plurality of reference points, or the like. 
     Thus, embodiments described herein provide, among other things, a power tool geofence tracking system and corresponding dashboard. The various dashboards generated by the mobile communications devices  110  provide, among other things, improved usability through efficient tracking data aggregation, analysis, and presentation. For example, in some embodiments, the mobile communications devices  110  determine tool tracking statistics and generate dashboards that simultaneously display multiple tool tracking statistics along with identifying information and configuration options.
