Efficient Power Consumption in CGM Devices

Continuous glucose monitoring system using lithium batteries that can have extended shelf life and reduced power consumption in sleep mode compared to existing continuous glucose monitoring devices. The system has a power interface detection module that checks the current and voltage. If they exceed a threshold, it disconnects the battery from the voltage regulator and connects just the battery and management module. This saves power as the regulator isn't needed. In this mode, the system can still monitor glucose but can't transmit data. It reconnects to the regulator for full functionality. This allows long-term storage without draining the battery.

Low-power dynamic blood glucose monitoring device for continuous glucose monitoring (CGM) systems that reduces power consumption compared to existing CGMs. The device has a bidirectional wake-up mechanism where it can actively wake up a host computer or be awakened by the host. It uses a FIFO buffer to save data during power off and enter low-power sleep states between samples. The device can be used in a system with a host computer to minimize power by waking up infrequently and communicating data in bursts.

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.

Modular continuous power supply system for glucose monitoring devices like continuous glucose monitors (CGMs) to improve battery life and enable longer monitoring periods. The system uses a redundant power architecture with a rechargeable supercapacitor as a backup power source. When connected to a battery, the supercapacitor charges continuously. If the battery is removed, the supercapacitor provides power to the CGM through a continuous power supply circuit. This prevents interruption of monitoring when the battery is swapped or removed.

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.

Continuous glucose monitoring device that can extend battery life without increasing size by using the glucose sensor itself as a power source when the main controller is sleeping. A battery management circuit connects the glucose sensor and storage battery. During normal operation, the glucose sensor provides data to the controller. When the controller sleeps, the battery management circuit switches to charge the battery from the glucose sensor's oxidation current. This self-powered feature extends device runtime without needing a separate battery.

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.

Continuous glucose monitor (CGM) for diabetics that eliminates the need to replace disposable batteries and sensors, reducing waste and cost. The CGM uses an energy conversion device with an oscillating weight and magnets to generate electricity from body motion. This replaces disposable batteries in the sensor. The generated power is stored in a rechargeable device and managed to optimize usage. The CGM continuously monitors blood glucose levels without needing finger pricks. The oscillating weight swings due to body motion and generates electricity from the magnetic field. This powers the CGM instead of disposable batteries. A rechargeable battery stores the generated power and a power management circuit optimizes usage. This avoids sensor battery replacement and waste.

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.

Energy utilization method for long-running autonomous monitoring devices that reduces power waste and enables stable operation without unnecessary power consumption. The method involves steps like power pre-reservation, timely start-up, and timely transmission to optimize power usage. The device harvests power from sources like capacitors, solar panels, piezoelectric, etc. and uses a trigger switch to selectively charge the main battery when a threshold is met. The device starts monitoring at predetermined intervals instead of continuously. Transmission occurs when monitored values exceed thresholds. This avoids unnecessary power consumption for repetitive monitoring and transmission. A timing controller activates the device at predetermined points to interrupt power between monitoring cycles.
