In some embodiments, the techniques may involve monitoring a wireless connection established between a portable computing device and a portable medicine delivery device. The techniques may also involve making a determination, based on the result of the monitoring, that the portable medicine delivery device is outside a predetermined range of the portable computing device. The techniques may further involve generating a notification based on the determination. The notification may be indicative of a user of the portable computing device being unaccompanied by the portable medicine delivery device. ## Claims ### Claim 1 A system comprising: one or more processors; and one or more processor-readable storage media storing instructions which, when executed by the one or more processors, cause performance of: monitoring a wireless connection established between a portable computing device and a portable medicine delivery device; making a determination, based on a result of the monitoring, that the portable medicine delivery device is outside a predetermined range of the portable computing device; and based on the determination, generating a notification indicative of a user of the portable computing device being unaccompanied by the portable medicine delivery device. ### Claim 2 (depends on 1) The system of claim 1, wherein making the determination comprises detecting that the wireless connection is lost. ### Claim 3 (depends on 1) The system of claim 1, wherein making the determination comprises detecting that the wireless connection has less than a predetermined strength. ### Claim 4 (depends on 3) The system of claim 3, wherein detecting that the wireless connection has less than the predetermined strength comprises comparing a received signal strength indicator to a predetermined threshold value. ### Claim 5 (depends on 1) The system of claim 1, wherein the one or more processor-readable storage media further store instructions which, when executed by the one or more processors, cause performance of: prior to making the determination that the portable medicine delivery device is outside the predetermined range, determining that the portable medicine delivery device is within the predetermined range; and storing a location record indicating a location of the portable medicine delivery device. ### Claim 6 (depends on 5) The system of claim 5, wherein the one or more processor-readable storage media further store instructions which, when executed by the one or more processors, cause performance of: accessing the location record for the portable medicine delivery device; and providing the user with the location of the portable medicine delivery device indicated in the location record. ### Claim 7 (depends on 6) The system of claim 6, wherein providing the user with the location of the portable medicine delivery device comprises displaying visual information for navigating to the location of the portable medicine delivery device. ### Claim 8 A processor-implemented method comprising: monitoring a wireless connection established between a portable computing device and a portable medicine delivery device; making a determination, based on a result of the monitoring, that the portable medicine delivery device is outside a predetermined range of the portable computing device; and based on the determination, generating a notification indicative of a user of the portable computing device being unaccompanied by the portable medicine delivery device. ### Claim 9 (depends on 8) The processor-implemented method of claim 8, wherein making the determination comprises detecting that the wireless connection is lost. ### Claim 10 (depends on 8) The processor-implemented method of claim 8, wherein making the determination comprises detecting that the wireless connection has less than a predetermined strength. ### Claim 11 (depends on 10) The processor-implemented method of claim 10, wherein detecting that the wireless connection has less than the predetermined strength comprises comparing a received signal strength indicator to a predetermined threshold value. ### Claim 12 (depends on 8) The processor-implemented method of claim 8, further comprising: prior to making the determination that the portable medicine delivery device is outside the predetermined range, determining that the portable medicine delivery device is within the predetermined range; and storing a location record indicating a location of the portable medicine delivery device. ### Claim 13 (depends on 12) The processor-implemented method of claim 12, further comprising: accessing the location record for the portable medicine delivery device; and providing the user with the location of the portable medicine delivery device indicated in the location record. ### Claim 14 (depends on 13) The processor-implemented method of claim 13, wherein providing the user with the location of the portable medicine delivery device comprises displaying visual information for navigating to the location of the portable medicine delivery device. ### Claim 15 One or more non-transitory processor-readable storage media storing instructions which, when executed by one or more processors, cause performance of: monitoring a wireless connection established between a portable computing device and a portable medicine delivery device; making a determination, based on a result of the monitoring, that the portable medicine delivery device is outside a predetermined range of the portable computing device; and based on the determination, generating a notification indicative of a user of the portable computing device being unaccompanied by the portable medicine delivery device. ### Claim 16 (depends on 15) The one or more non-transitory processor-readable storage media of claim 15, wherein making the determination comprises detecting that the wireless connection is lost. ### Claim 17 (depends on 15) The one or more non-transitory processor-readable storage media of claim 15, wherein making the determination comprises detecting that the wireless connection has less than a predetermined strength. ### Claim 18 (depends on 17) The one or more non-transitory processor-readable storage media of claim 17, wherein detecting that the wireless connection has less than the predetermined strength comprises comparing a received signal strength indicator to a predetermined threshold value. ### Claim 19 (depends on 15) The one or more non-transitory processor-readable storage media of claim 15, wherein the one or more processor-readable storage media further store instructions which, when executed by the one or more processors, cause performance of: prior to making the determination that the portable medicine delivery device is outside the predetermined range, determining that the portable medicine delivery device is within the predetermined range; and storing a location record indicating a location of the portable medicine delivery device. ### Claim 20 (depends on 19) The one or more non-transitory processor-readable storage media of claim 19, wherein the one or more processor-readable storage media further store instructions which, when executed by the one or more processors, cause performance of: accessing the location record for the portable medicine delivery device; and providing the user with the location of the portable medicine delivery device indicated in the location record.
