The cover 14 and case back 28 are constructed and arranged for collectively positioned about the printed circuit board 25 and battery/button cell 29. A preferential attribute of this embodiment is to have highly thermal conducting vias (or through elements, which are typically metal such a copper; see 27 of FIG. 11) in the printed circuit board 25 under the thermal sensor 26 and thermal media (e.g., paste or epoxy or thermal grease or similar) is added onto the inside of temperature probe 8 such that when device 2 is assembled, the thermal paste physically connects the temperature probe 8 to the thermal vias (27 of FIG. 11) under thermal sensor 26 such that the heat from the end-user efficiently travels from the skin through the thermal probe 8 through the thermal paste through the vias (27 of FIG. 11) to the thermal resister 26. Alternatively, the printed circuit board 25 may be made of highly thermally conductive material and this may be used instead of the vias under the thermal sensor 26 may be a thermal resistor element or preferably an integrated thermal sensor such as a silicon bandgap temperature sensor. Thermal conductivity of material in vias is greater than 1 W/mK and preferably greater than 10 W/mK.

    [0092] FIG. 11 illustrates the back exploded view of the parts of the device of FIG. 7 with cover 14, printed circuit board 25, thermal vias 27 (the hole or holes through the printed circuit board that are filled with metal or highly thermally conductive material), battery/button cell 29, case back 28, battery recharging pins 7, and skin temperature probe 8.

    [0093] FIG. 12 is a flow chart of a method for administering PHM devices in the context of an organization that manages a group of end-users with the intent to provide some level of safety through the monitoring and management of PHMs. End-user personal heath monitors (PHMs) are shown using symbol 30, mobile electronic devices (MEDs), such as cell phones are shown with symbol 31. Communications between the PHMs 30 and MEDs 31 are shown in dashed lines 42. Communications between MEDs 31 and the internet 36 are shown in dotted lines 35. Communications between the internet 36 and the database 40 and an organization systems' application programming interface (API) 41, organization 38, and access points 37) are shown in solid lines 39. Groups of many devices 30 may connect through a single MED 31 such as in grouping 33 and grouping 34 or a single device 30 may connect through the end-user's personal MED 31 as in the one-to-one pairing in 32. In the preferred method, groupings many devices 30 may connect through one MED 31 as shown in groupings 33 and 34. It is highly preferable that all data communications are done with appropriate prior legal permission and data is encrypted and transmitted in a secure way. In the preferred method, the internet 36 is used to connect device data from MEDs 31 to the database 40. Likewise, the database may communicate back down to the device using the same pathway to send updated operating parameters or software/firmware to the devices 30. Similarly, the application or “app” on the MED 31 may be updated from the database (or app provider such as Google Play or Apple App Store). In addition, database may update parameters in the device 30 (transmitting through MED 31) and/or MED 31 such as health information, warning language, parameters to determine when warnings are triggered, device firmware, and historical data. An application program interface (API) 41 is used for the organization 38 to access data from the database to monitor constituents of the organization who have given permission for organization to access such data or for which organization has legal right to view data. API 41 may also be a website portal with security and login that provides a user interface to administrators of the organization 38 to see the status and history and data of end-users from its organization. Physical access points to the organizations such as door entries 37 may be equipped with RFID readers (or similar technology) which read end-user identification data (such as student ID number or employee ID number) as the end-user enters or approaches the organization. The access point 37 preferably relays the end-user ID information and the access location to the organization system 38 and/or database 40 where the person ID is matched up with that person's end-user PHM health status from the database (either directly or through API) and if end-user/person entering access point is deemed by database (or organization system) to be a health risk, then an alarm or notification will be alerted by one or more of: the access point physical location (such as with an alarm sound and/or lights), the organization API, the organization web portal, the organization administrator(s) MEDs, the end-user MED, and the end-user custodial/family member(s) MEDs. Email and text notification may also be send to any of the persons mentioned.

    [0094] It is to be understood that the foregoing description is intended to illustrate and not to limit the scope of the invention, which is defined by the scope of the appended claims. Other embodiments are within the scope of the following claims.
