11 patents in this list
Updated:
Due to their ability to provide real-time glucose level data, continuous glucose monitoring (CGM) devices are vital tools in diabetes management.
It is essential to optimize power usage to improve user convenience and device longevity. This entails creating gadgets that strike a compromise between precise glucose monitoring and effective energy consumption.
Innovative ways of data transmission, component optimization, and battery management are needed to achieve this, which are discussed on this page.
1. Battery Life Optimization and Management in Wearable Glucose Monitoring Devices
Dexcom, Inc., 2023
Analyte sensor system worn by a user that monitors battery life and extends battery usage. The system measures battery power level and predicts remaining life based on usage assumptions. It then adjusts sensor operations like data transmission if the battery is low. This prolongs sensor system operation by skipping transmissions when the battery is low instead of draining it further.
2. Energy-Efficient Data Management in Continuous Glucose Monitoring Systems
I-SENS, INC., 2023
Transmitting and receiving biometric information between a sensor and a device in a continuous monitoring system reduces the load of determining whether biometric information was received at every regular interval. Instead, it checks for unreceived data only at longer non-receipt intervals and selectively requests missing data if needed. This reduces processing and energy waste compared to constant checking.
3. Integrated Glucose Monitoring System for Reduced Power Consumption and Enhanced Convenience
Tula Health, Inc., 2023
Integrated glucose monitoring system that combines a glucose meter, mobile device, and housing into a single unitary device for convenient and less invasive glucose monitoring. The integrated system eliminates the need for separate glucose meters and mobile devices. The housing surrounds both devices, providing easy access and management of supplies. The integrated system reduces discomfort, the spread of disease, and the burden of managing separate devices.
4. Energy-Efficient Component Management in Continuous Glucose Monitoring Devices
Abbott Diabetes Care Inc., 2022
Selectively disabling components of a medical device like a continuous glucose monitor during data transmission to reduce noise and improve signal quality. The device determines the battery temperature and charge level and disables components when thresholds are reached to prevent issues like desensitization or corruption. It also selectively disables components during data reception windows to reduce noise. This allows enhanced and more accurate signal transmission and reception.
5. Touch and Light-Activated Power Management for Glucose Monitoring Devices
I-SENS, INC., 2022
Body attachable glucose monitoring device that can be easily powered on and operated using light or touch commands instead of physical buttons. The device has a housing, sensor, PCB, battery, and connection control unit. The connection control unit generates a connection signal to electrically connect the battery and PCB based on user input from a touch panel or optical receiver. This allows powering the device before and after attachment without physical buttons. A blocking film covers the input to prevent accidental activation.
6. Adaptive Power Management Techniques for Glucose Monitoring Devices
ABBOTT DIABETES CARE INC., 2022
Efficiently changing the power state of devices like glucose sensors to reduce energy consumption while maintaining functionality. The techniques involve using external stimuli like light or magnetic fields to activate the device without powering on the entire circuitry. This allows activating the device before attaching it to the body. Wireless communications can also be used to adaptively change the power mode by monitoring the device and increasing the communication power until enough is supplied to transition to a higher power mode.
7. Integrated Multi-Analyte Sensing for Automated Insulin Delivery in Continuous Glucose Monitoring Systems
PercuSense, Inc., 2022
A minimally invasive multi-analyte continuous glucose monitoring (MCGM) system that enables automated insulin delivery for diabetes management. The system uses a single probe inserted under the skin to continuously monitor glucose and at least one other analyte like lactate or ketones. Integrating multiple signals from the same probe reduces the burden compared to multiple sensor insertions. The combined biochemical and physical data allows automated insulin delivery algorithms to refine personalized treatment and anticipate glucose changes based on context like meals, exercise, stress, and sleep.
8. Power-Efficient Data Transmission System for Continuous Glucose Monitors
DexCom, Inc., 2022
System for transmitting data from a continuous glucose monitor to a display device with power-saving features. The monitor and display communicate using a two-way channel. The monitor can be woken up from low-power sleep by the display using NFC. This reduces power compared to continuous transmission. The monitor can also detect excess current during sleep to determine if it's awake. The display can also request a transmission pause mode. The monitor can provide a reduced power state during this time. The display can also request adjustments to sensor data based on leakage current.
9. Self-Powered Glucose Sensor with RFID Transmission for Optimized Power Consumption
Abbott Diabetes Care Inc., 2022
Self-powered glucose sensor that does not require a separate battery. The sensor has an integrated circuit with a capacitor to store charge from the sensor's electrical signals. When a nearby device with a strong magnetic field passes, it latches a switch to connect the capacitor to the circuit components. This provides power to process the stored sensor signals and transmit glucose levels using RFID. The sensor and electronics are sealed in a sterilizable housing.
10. Autonomous Power Management for Continuous Analyte Monitoring in Implantable Sensors
Senseonics, Incorporated, 2021
Implantable sensor for continuous monitoring of analytes in body fluids like blood, saliva, etc. The sensor has an internal power source (charge storage device) and an inductive element for wireless communication. It can take measurements when not near an external power source by using internal power. When near the external device, it wirelessly transmits stored measurements. A scheduler issues autonomous measurement commands based on an internal clock to periodically measure when not near the external device. This allows continuous monitoring without relying solely on external power.
11. Dual-Processor Approach for Power Optimization in Continuous Glucose Monitoring Devices
Roche Diabetes Care, Inc., 2020
A handheld diabetes management device that separates the power consumption of the communications module from the user interface module to optimize battery life. The device has a separate processor for collecting and storing continuous glucose monitoring (CGM) data from a CGM device, and a separate processor for displaying the CGM data to the user. The CGM data collection processor operates at a lower power rate than the user interface processor to save battery. This allows asynchronous data collection and reporting to reduce power consumption.
