A system for detecting placement or misplacement of an object includes a wireless tag; a first electronic device (“FED”) associated with the tag to automatically detect signals from the tag, determine a position of the FED, transmit the position and status to an external electronic device or network (“EED”) in response to the status indicating that the tag and the FED are within a predetermined range, and transmit the position and status to the EED in response to the status indicating that the tag and the FED are outside of the predetermined range; and a second electronic device (“SED”) that is unassociated with the tag to automatically detect signals from the tag, determine a position of the SED, determine an identifier for the tag using the signals, and transmit the position of the SED and the identifier to the EED.

A system and method for location tracking using Bluetooth Low Energy tracking devices or tags having a button, a light, a sound generating buzzer, and a user replaceable battery are disclosed. The system may include one or more Bluetooth receiving units, which may be user mobile devices, programmed to receive a signal from one of the tracking devices and send the location of the tracking device to the system. The advertising interval or transmission frequency of the tracking devices may be raised or lowered to either increase the location precision or extend the battery life of the tracking devices. In one embodiment, tracking devices may be attached to automobile keys and the automobile's vehicle identification number may be associated with the corresponding tracking device, to allow an automobile dealership to manage the location of a large quantity of keys.

Methods and systems for tracking a supply chain of a package by using a barcode and a plurality of mobile devices are provided. The methods at least includes issuing and scanning the barcode at an initial location, pairing the barcode with a first mobile device, receiving transaction information of the package to update the barcode to include the transaction information, validating the barcode with a first digital signature, unpairing the barcode with the first mobile device, scanning the barcode by a second mobile device, and pairing the barcode with the second mobile device, validating the barcode with a second digital signature, tracking a location of the package that is moving along with the second mobile device. Tracking is continued until the package is arrived at a final destination. Validated data is further confirmed by a third party to increase credibility of tracking information.

A caregiver location system includes a computer configured to track a location of a caregiver in a healthcare facility. A caregiver identification (ID) tag is worn by a caregiver and has a tag transmitter configured to communicate with a plurality of receivers. The plurality of receivers and the computer cooperate to form a locating system that is operable to determine a location of the caregiver ID tag. The computer collects data over time related to a caregiver location within the healthcare facility and determines a problem area within the healthcare facility where a determined caregiver location is inaccurate.

Provided is a transmitting device for a cart with an auto following function, which can sense the position and moving path of a user and move while following the user.

The transmitting device for a cart provides a sensing and communication function such that the cart with the auto following function can sense and follow the position of the transmitting device. Thus, the cart can sense and follow the position of the transmitting device.

Furthermore, since the transmitting device for a cart can be conveniently worn like a watch, a user's convenience can be improved.

A Smart Campus Security Shield System comprising a Smart Student ID Card, wherein the card comprises a set of sensors inside the Smart Student ID Card. The set of sensors send a crime alert through a wireless network to a cloud server. The cloud server memory comprises a student crime alert model which describes the crime alert severity, student ID number, name, location, date, time, and a set of details of the student, so that the student risk control model can generate a plurality of corrective actions and preventive actions for each individual student. The crime alerts personalized and adaptive machine learning method presents a set of customized corrective actions and preventive actions to a student, based on at least one student attribute data. A set of student safety performance statistics is used to generate an optimal safety management strategy for the school security staff to reduce school crime.

Systems and methods for operating an Electronic Smart Tag (“EST”). The methods comprise: harvesting, by an energy harvesting circuit of the EST, energy from an external energy source; using the energy to power at least a receiver and a display device of the EST; performing signal reception operations by the receiver to receive an original information bearing signal modulated in the external energy source; processing the original information bearing signal to obtain item related information therefrom; and causing the item related information to be displayed on the display device.

A caregiver location system includes a computer configured to track a location of a caregiver in a healthcare facility. A caregiver identification (ID) tag is worn by a caregiver and has a tag transmitter configured to communicate with a plurality of receivers. The plurality of receivers and the computer cooperate to form a locating system that is operable to determine a location of the caregiver ID tag. The computer collects data over time related to a caregiver location within the healthcare facility and determines a problem area within the healthcare facility where a determined caregiver location is inaccurate.

Disclosed herein are tracking and analysis devices, systems, and methods for optimizing workflow operations using the tracking and analysis devices and a plurality of movable and fixed tracking beacons. The movable tracking beacons may be configured for secure attachment to, or incorporation within, mobile workflow assets, while the fixed tracking beacons may be placed around the workflow environment in a grid-pattern. The tracking and analysis devices, as well as the movable and fixed tracking beacons, may each comprise any combination of a: battery, a low frequency Bluetooth module, an accelerometer, a Wi-Fi module, a USB hub, and/or an RFID reader/scanner. The tracking and analysis device may track and identify a workflow asset's location within a workflow environment within a range of about 2-3 feet by receiving and comparing relative signal strength of low frequency Bluetooth signals received from the movable tracking beacons and/or the plurality of fixed tracking beacons.
