Abstract
A monitoring system for obtaining a video related to medication adherence of a user, includes: a wireless communication device comprising a motion sensor, an ambient light sensor, a first transceiver transmitting data to an external device, and a first controller configured to control the motion sensor, the ambient light sensor, and the first transceiver, the wireless communication device having an attaching portion for being attached to an object containing a medication; and a wearable device including a camera, a second transceiver receiving a signal from the first transceiver, and a second controller configured to obtain video data through the camera based on the signal received through the second transceiver.
Core Innovation
A wearable electronic device includes a camera, a communication circuit, and at least one processor configured to establish a communication connection with an external electronic device positioned within a specific distance at a first time point. The processor receives data for an activation of the camera at a second time point after the first time point and obtains a received signal strength indicator (RSSI) value corresponding to the second time point, where the RSSI value is related to a distance between the wearable electronic device and/or the external electronic device and an environment around the wearable electronic device.
Based on the RSSI value being included in a specific range, the processor activates the camera to capture at least one image based on the activation data. Based on the RSSI value being out of the specific range, the processor disregards the data so that the camera is not activated. In this way, the decision to activate the camera is controlled using an RSSI-based range condition tied to distance and/or environment.
A system is also described in which a wireless electronic device having a motion sensor and a first communication circuit transmits data for activation of the camera to a wearable electronic device having a camera and a second communication circuit. The wearable device receives the activation data, obtains an RSSI value corresponding to the time point at which the data is received, and activates the camera to capture at least one image based on whether the RSSI value is included in a specific range or disregards the data when the RSSI value is out of the specific range.
Claims Coverage
The document contains two independent claims. Both independent claims cover controlling camera activation in a wearable electronic device using activation data and an RSSI-based specific-range decision; one independent claim adds short-range communication constraints from an external electronic device, and the other independent claim adds a two-device system where motion-derived activation data is transmitted from a wireless motion sensor device to the wearable camera device.
RSSI-gated camera activation using distance/environment range
A wearable electronic device activates its camera to capture at least one image based on received activation data only when a corresponding RSSI value is included in a specific range related to a distance between the wearable electronic device and/or the external electronic device and an environment around the wearable electronic device; otherwise the device disregards the data so the camera is not activated.
Short-range communication with later activation data
The wearable electronic device establishes a communication connection with an external electronic device positioned within a specific distance at a first time point, receives camera-activation data at a second time point after the first time point, obtains an RSSI value corresponding to the second time point, and performs the RSSI-specific-range decision to activate or disregard the data.
Motion-sensor wireless device transmitting activation data to wearable camera
A system includes a wireless electronic device with a motion sensor that obtains activation data for camera activation based on a motion value and transmits the activation data to a wearable electronic device, where the wearable device receives the activation data, obtains an RSSI value corresponding to the reception time, and activates the camera to capture at least one image based on whether the RSSI value is included in a specific range or disregards the data when out of the range.
Across the independent claims, the main claim coverage is the RSSI value being related to distance/environment and being used to gate whether activation data results in camera capture versus being disregarded, applied either to an external device that is within a specific distance or to a system where motion-derived activation data is transmitted from a wireless motion sensor device to a wearable camera device.
Stated Advantages
Disregarding activation data so the camera is not activated when RSSI is out of the specific range to prevent unnecessary video capture.
Protecting privacy by gating camera activation based on RSSI range.
Documented Applications
Medication adherence monitoring using a motion sensor and ambient-light threshold conditions to generate activation data and server-side video analysis to determine whether the user performed medication adherence.
Multiple medications monitoring by handling multiple medications and/or multiple wireless devices.
Health management actions extension to other health management actions including blood pressure, glucose, ECG, and temperature.
