Abstract

A host device and temperature monitoring device (TMD) integrated assembly that can automatically collect temperature data and interface with a workflow management system. The TMD is provided in a portable housing and incorporates one or more temperature sensors, such as a physical probe, infrared sensor, or RFID transceiver, along with an interface for communicating via a wired connection with a host device that has been programmed with temperature management tasks. The TMD may be used to automatically collect temperatures and provide the data to the host for monitoring and tracking as part of a comprehensive workflow management system that includes food safety monitoring and compliance programs.

Claims

1. A system for managing the collection and monitoring of the temperatures of a plurality of targets, comprising:

an integrated assembly comprising a host device and a separate temperature monitoring device, the host device being a mobile device, coupled to the temperature monitoring device, said temperature monitoring device including a housing having a host interface adapted for wired communication with said host device, said housing removably attached to said host device, a microcontroller communicatively interconnected to the host interface and positioned within said housing, an infrared temperature sensor interconnected to said microcontroller, a radiofrequency identification transceiver interconnected to said microcontroller, and a temperature probe attached to said housing and interconnected to said microcontroller so that said microcontroller can selectively activate per inputs received from the host interface one or more of said sensor, transceiver and probe;

wherein said temperature probe is attached to said housing via an external cable which connects said temperature probe to said host interface via said microcontroller;

a remote server interconnected to said host device, wherein said server is programmed to provide said host device with at least one temperature monitoring task requiring a user of said integrated assembly to obtain a temperature of one of said plurality of targets per the use of at least one of said infrared temperature sensor, said radiofrequency identification transceiver and said temperature probe;

wherein said host device is programmed to require the use of said infrared temperature sensor when said at least one temperature monitoring task is from a first set of temperature monitoring tasks;

wherein said host device is programmed to require the use of said radiofrequency identification transceiver when said at least one temperature monitoring task is from a second set of temperature monitoring tasks; and

wherein said host device is programmed to require the use of said temperature probe when said at least one temperature monitoring task is from a third set of temperature monitoring tasks.

2. The system of claim 1, wherein said host device is programmed to display said at least one temperature monitoring task for said user and allow said user to provide said temperature to said host device via said temperature monitoring device per said wired communication.

3. The system of claim 1, wherein said temperature monitoring device further comprises a barcode scanner.

4. The system of claim 3, wherein said host device is programmed to require the use of said barcode scanner when said at least one temperature monitoring task is from a fourth set of temperature monitoring tasks.

5. The system of claim 1, wherein said host device is programmed to send a command via said wired communication to said temperature monitoring device that enables:

said infrared temperature sensor when said at least one temperature monitoring task is from the first set of temperature monitoring tasks;

said radiofrequency identification transceiver when said at least one temperature monitoring task is from the second set of temperature monitoring tasks; and

said temperature probe when said at least one temperature monitoring task is from the third set of temperature monitoring tasks.

6. The system of claim 5, wherein said microcontroller of said temperature monitoring device is programmed to collect temperature data using the enabled one of said sensor, transceiver and probe when triggered by user.

7. The system of claim 6, wherein said microcontroller of said temperature monitoring device is programmed to export said temperature data to said host device via said wired communication.

8. The system of claim 7, wherein said host device is programmed to validate said temperature data for compliance with predetermined requirements.

9. The system of claim 8, wherein said temperature monitoring device is programmed to obtain location data from a tag positioned at a predetermined location via said transceiver in addition to obtaining temperature data via one or more of said sensor and said probe.

10. The system of claim 9, wherein said host device is programmed to inhibit the use of one or more of said sensor, transceiver and probe based on said at least one task.
