## Title
Offender monitor messaging system

## Abstract

An officer can utilize an offender monitor to track remotely and manage the whereabouts of an offender, such as someone who as been convicted of a crime and is on parole. The officer can compose and send custom messages to send to the offender via the offender monitor. The offender monitor can store a received message so that the offender can play the message at an appropriate time via pressing a button on the offender monitor or making another input. If the officer deems that a message is urgent or needs to be played immediately, the officer can transmit a command to the offender monitor that causes the message to be played automatically.

## Background
TECHNICAL FIELD
The present technology relates generally to offender monitors for tracking locations of offenders, and more particularly to transmitting prioritized messages to offenders via their offender monitors.
BACKGROUND
Situations arise where an officer or other person would like to send a message to an offender who is being monitored by an offender monitor. If the offender is not carrying a conventional cell phone or the offender's cell phone is not operational due to depleted batteries or another issue, then communicating with the offender may not be feasible with conventional technologies.
Accordingly, need exists for communicating reliably with offenders who are being monitored by offender monitors. A technology addressing such a need, or some related deficiency in the art, would improve offender-monitoring programs.
SUMMARY
An offender monitor can remotely track an offender, for example someone who as been convicted of a crime and is on parole or someone who is under a court-ordered restriction. An officer can utilize the tracking capabilities to help manage the offender, for example to confirm that the offender is complying with any restrictions on locations or movements. The officer can compose and send messages to send to the offender via the offender monitor. In one aspect of the disclosure, the offender monitor can store a received message so that the offender can play the message at an appropriate time via pressing a button on the offender monitor or making another input. In another aspect of the disclosure, if the officer determines that a stored message needs to be played immediately, the officer can transmit a command to the offender monitor that causes the stored message to be played. In another aspect of the disclosure, the officer can send a priority message that is automatically played upon receipt by the offender monitor.

U.S. Pat. No. 8,115,621, issued Feb. 14, 2012 in the name of Yoganand Rajala and Steve Aninye and entitled “Device for Tracking the Movement of Individuals or Objects” discloses some example embodiments of an offender monitor 100 and is hereby incorporated herein by reference.
Turning now to FIG. 2, this figure illustrates an example operating environment for the offender monitor 100 according to some embodiments of the present technology. In the illustrated embodiment, the operating environment comprises a cellular system 200. As illustrated, the offender monitor 100 is located near two cell towers 250 and may communicate with either via respective communication channels 275. The cell towers 250 communicate with a server 210 over a network 205. In some example embodiments, the network 205 comprises the Internet.
A user station 225 is also connected to the network 205. The user station 225 can communicate with the offender monitor 100 through the server 210, or alternatively directly. The user station 225 provides an interface through which a user, for example an officer such as a parole officer or official, can interact with the offender monitor 100 and the server 210. The officer may track offender movements and historical movement patterns through the user station 225, for example. In various embodiments, the user station 225 can comprise a smartphone or other handheld device, a laptop, a workstation, a personal computer, or other appropriate system.
The server 210 can provide location services for the offender monitor 100 as well as for other monitors (not illustrated) that may be attached to other people or objects. Additionally, the server 210 can store configuration data that may be downloaded to the offender monitor 100, such as during startup or rebooting. In an example embodiment, the server 210 may comprise an Internet connection, a processor, and memory. In some example embodiments, the server 210 can comprise a group or cluster of servers acting as a single logical entity.
Turning now to FIG. 3, this figure illustrates a functional block diagram for the example offender monitor 100 according to some embodiments of the present technology. In the illustrated embodiment, the offender monitor 100 comprises a cellular module, a GPS receiver 350, a microcontroller system 325, and an input/output system 310, all of which are powered by one or more on-board batteries 375. The cellular module 305 comprises an example embodiment of a radio. The GPS receiver 350 comprises an example embodiment of a location detector.
In various embodiments, the offender monitor 100 may further comprise gyroscope, a tamper detector, a switch, and other appropriate elements, for example. Example tamper detectors can include switches that open or close to provide an electrical signal when the housing 310 is opened or otherwise breached, fiber optic strands that are embedded in the strap 105 to break and stop transmitting an optical signal when the strap 105 is compromised, and other appropriate tamper sensing devices.
In the illustrated embodiment of FIG. 3, the input/output system 310 comprises an input device 311 and a messaging output device 312. The input device 311 accepts inputs from the offender/user to interact with or control some aspects of the offender monitor 100. The offender can use the input device 311 to access and play messages stored in the offender monitor 100, for example. Example embodiments of the input device 311 can comprise a microphone for receiving voice commands, a button, a touch pad, or some other appropriate device. The messaging output device 312 outputs messages from the offender monitor 100 for receipt by the offender. Example embodiments of the messaging output device 312 can comprise a speaker, a transducer for converting electrical signals into vibrations that can propagate through air as sound, a vibrating component that vibrates in manner that the offender can perceive via feel or tactilely, a light that flashes, or some other appropriate device.
In operation, the cellular module 305 maintains a connection to one or more cell towers 250 over one or more wireless channels 275 through a wireless network as illustrated in FIG. 2. In an example embodiment, the cellular module 305 continuously or regularly attempts to keep a cellular connection available to the tower 250. In such an embodiment, the server 210 can control the operation of the offender monitor 100 by sending commands or other data to the monitor 100. In various embodiments, the cellular module 305 can comprise CDMA, GSM, UMTS, HSPA, or LTE technologies. In some example embodiments, the cellular module 305 and the GPS receiver 350 are integrated into a single modem module or chip or chip set.
When triggered by the microcontroller system 325, a GPS location reading occurs on the GPS receiver 350. That is, the GPS receiver 350 acquires a location reading or GPS data. The microcontroller system 235 can further control the cellular module 305 in connection with transmitting acquired location data (GPS or otherwise), notifications, alarms, and other appropriate data (to the server 210 or other recipient) and with receiving commands and other data. In some embodiments, location information is obtained utilizing cell-tower-based triangulation, such as advanced forward link trilateration (AFLT), or using a signal-strength-based location approach, such as received signal strength indicator (RSSI) based on tower or Wifi signals. The offender monitor 100 can utilize such technologies as embodiments of a location detector to augment or support, or as a substitution for, satellite-based location tracking. Further, GPS tracking can utilize assisted GPS (A-GPS) to improve location acquisition speed.
In an example embodiment, the microcontroller system 325 comprises a low-power microcontroller and associated memory 330. The microcontroller system 325 can comprise a microprocessor or other appropriate processor, for example. Example embodiments of the memory 330 can comprise volatile and nonvolatile memory, such as random access memory (RAM) and flash memory for example. In an example embodiment, the memory 330 can comprise firmware for executing management and control functions. For example, the memory 330 can comprise persistent memory that stores program code, including a messaging engine 333. An example embodiment of the messaging engine 333 comprises computer executable instructions for receiving, processing, and playing prioritized messages on the offender monitor 100. Accordingly, the instructions may be executed by the microcontroller system 325 or other appropriate computer-, controller-, or microprocessor-based system. For example, the messaging engine 333 can comprise code for implementing process 500 that is illustrated in flowchart form in FIG. 5 and discussed below.
Turning now to FIG. 4, this figure illustrates an example of the offender monitor 100 in which the messaging output device 312 is enclosed within and mounted to the housing 110 according to some embodiments of the present technology. In the illustrated embodiment, the housing 110 is waterproof and submersible so that the offender can immerse the offender monitor 100 in water without risk of water incursion damaging the electrical system or internal elements of the offender monitor 100.
As illustrated, the messaging output device 312 comprises a transducer that converts electrical signals conveying a message into vibrational signals conveying the message. In some embodiments, the transducer can comprise a speaker in which the vibrations radiate from the transducer as sound in air. In some examples, the transducer of the messaging output device 312 is mounted to the housing 110 so that the vibrational signals transmit directly to the housing 110, without an air gap. In such an embodiment, the housing 110 vibrates directly from vibrations of the transducer, and the housing vibrations set up vibrations in air that radiate from the housing 110 of the offender monitor 100 as sound. The vibrations can transfer from the transducer to the housing 110 by mounting the transducer to an interior wall or other structure of the housing 110 or by connecting the transducer to the housing structure with a vibration bridge or horn or other solid connection that couples the transducer vibrations into the housing 110 without an air gap.
An example embodiment of a process 500 for messaging an offender will now be described in further detail with reference to the flowchart illustrated in FIG. 5. Example reference will further be made to the preceding figures, without limitation. In some example embodiments, instructions for execution of the process 500 that FIG. 5 describes can be stored in the memory 330 and executed by the microcontroller system 325 of the offender monitor 100. As discussed above, process 500 can comprise an executable embodiment of the messaging engine 333 maintained on the memory 330.
At block 510 of process 500, the officer composes and enters a message into the user station 225 and designates the message as regular or high priority. In various embodiments, the priority designation can be transmitted as a flag, as metadata, or via other appropriate indication of priority. The officer can compose the message via a voice recording or via typing a custom message on a keyboard, for example. In some other embodiments, the officer may select messages from a menu.
At block 520 of process 500, the user station 225 transmits the message to the offender monitor 100, and the offender monitor 100 receives the message. In some embodiments, the message transmits as a wave file. In some other embodiments, the message transmits as an SMS message. The message may be transmitted over a cellular system 200 as illustrated in FIG. 2 and discussed above, for example.
At inquiry block 530 of process 500, the microcontroller system 325 of the offender monitor 100 determines whether the message was transmitted as a high priority message or as regular priority message.
If the message was transmitted as a high priority message, then process 500 branches to block 560. At block 560, the offender monitor immediately plays and delivers the message, without input from the offender. In some embodiments, the offender monitor plays a wave file as a voice recording. In some embodiments, the offender monitor 100 synthesizes speech according to a received SMS message.
In the illustrated embodiment, process 500 ends following execution of block 560. Process 500 can iterate from block 560 to process additional messages sequentially or in parallel, for example.
If the microcontroller system 325 makes a determination at inquiry block 530 that the message was designated as normal priority, then process 500 executes block 540 from block 530 rather branching to block 560.
At block 540, the offender monitor 100 issues a notification to the offender of receipt of the message and stores the message, for example in the memory 330. The offender monitor 100 can notify the offender by vibrating in a manner that the offender perceives via the offender's sense of touch through skin, via an audible beep, via a blinking light, or via some other appropriate output.
At inquiry block 550, the microcontroller system 325 determines whether the offender has selected to play the message (for example via the input device 311 as discussed above) or whether the officer (via the user station 225) has issued a play command received at the offender monitor 100 sometime after receipt of the message and storage of the message. If the offender has not selected to play the message and the offender monitor 100 has not received a play command, then process 500 iterates inquiry block 550 until one of those conditions has been satisfied.
When either the offender has selected to play the message or the officer has issued a play command, then the offender monitor 100 plays the message at block 560 as discussed above, and process 500 ends.
Example embodiments of process 500 support messaging flexibility, so that an officer can avoid interrupting the offender with a non-critical message at an inappropriate time, for example while the offender is at a church service. However, the officer can elect to force playing of a stored message when the officer deems immediate delivery important, for example when the offender is out past a curfew or is in an impermissible location, such as near a victim's residence. The officer can further deliver priority messages for play-on-delivery, when the officer deems immediate delivery is warranted. In another exemplary embodiment of process 500, the messaging feature can be disabled to prevent an exchange of communications between an officer and the offender that are deemed to be confidential or legally privileged communications.
Technology for messaging offenders has been described. From the description, it will be appreciated that embodiments of the present technology overcome limitations of the prior art. Those skilled in the art will appreciate that the present technology is not limited to any specifically discussed application or implementation and that the embodiments described herein are illustrative and not restrictive. From the description of the exemplary embodiments, equivalents of the elements shown therein will suggest themselves to those skilled in the art, and ways of constructing other embodiments of the present technology will appear to practitioners of the art.
