Disclosed herein are methods and systems for conserving energy of a power source of an analyte monitoring device, including entering a power saving mode based on at least one of a temperature level of a power source, a level of power of a power source, or an amount of power needed by at least one component. Also disclosed herein are methods and systems for reducing noise during data transmissions to and from the analyte monitoring device.

Analyte monitoring system and methods for managing power and noise

Methods and devices to monitor an analyte in body fluid are provided. Embodiments include continuous or discrete acquisition of analyte related data from a transcutaneously positioned in vivo analyte sensor automatically or upon request from a user.

Medical devices and methods

Disclosed embodiments include methods and systems including a receiver unit of a glucose monitoring system. The receiver unit is configured to receive a key associated with a transmitter unit that enables the receiver unit to identify the transmitter unit, initiate communication with the transmitter unit, access a communication key uniquely associated with the transmitter unit, and receive communication packets from the remote transmitter unit on a periodic basis including data indicative of a glucose level of a bodily fluid. The receiver unit is further configured to process the data determine the glucose level for display, output a numerical representation of the determined glucose level in a GUI, and transmit data indicative of the glucose level to a second receiver unit.

Analyte monitoring system and methods

Embodiments that translate a sensor measurement to a frequency characteristic are disclosed. The frequency characteristic can be wirelessly detected by a reader device. The detected frequency characteristic can be used to determine the corresponding sensor measurement. Devices utilizing this approach can be characterized or calibrated to increase accuracy. Systems and methods utilizing the approaches are also described.

Systems, devices, and methods for RF detection of analyte sensor measurements

A medical device includes an antenna external to a case, package, or encapsulant for the electronic systems of the medical device. In one embodiment, a diabetes infusion pump is enclosed within a metal case, the pump including a processor and a communication module for wireless communications. An antenna is disposed in the delivery tubing of the pump outside the case with an antenna feed interconnecting the external antenna with the internal communication module. In another aspect, a thin film antenna is formed on the outer surf ace of the case in which a physiological parameter sensor, such as a glucose sensor, is enclosed. Multiple antennas may be used for communications on different frequencies.

Medical device antenna systems having external antenna configurations

Methods and systems for providing data communication in medical systems are disclosed.

Systems, devices, and methods are provided for changing the power state of a sensor control device in an in vivo analyte monitoring system in various manners, such as through the use of external stimuli (light, magnetics) and RF transmissions.

Systems, devices, and methods for energy efficient electrical device activation

Methods and devices to monitor an analyte in body fluid are provided. Embodiments include continuous or discrete acquisition of analyte related data from a transcutaneously positioned in vivo analyte sensor automatically or upon request from a user. The in vivo analyte sensor is coupled to an electronics unit holding a memory with instruction to cause processing circuitry to initiate a predetermined time period that is longer than a predetermined life of the sensor, during the predetermined time period, convert signals from the sensor related to glucose to respective corresponding glucose levels, without relying on any post-manufacture independent analyte measurements from a reference device, and at the expiration of the predetermined time period, disable, deactivate, or cease use of one or more feature.

An antenna is disposed in the delivery tubing of the pump outside the case with an antenna feed interconnecting the external antenna with the internal communication module. In another aspect, a thin film antenna is formed on the outer surface of the case in which a physiological parameter sensor, such as a glucose sensor, is enclosed. Multiple antennas may be used for communications on different frequencies.

Systems, devices and methods are provided that allow for enhanced performance, power efficiency, interoperability, data security and user privacy for in vivo analyte monitoring systems that utilize wireless communications. The in vivo analyte monitoring systems can include a Bluetooth or Bluetooth Low Energy enabled handheld relay device for wirelessly relaying analyte data between a sensor unit device and one or more reader devices. The in vivo analyte monitoring systems can employ advertisement and encryption schemes for wirelessly transmitting data in a manner that allows for improved security, efficiency and privacy.

Systems, devices, and methods for wireless communications in analyte monitoring systems

Disclosed embodiments include methods and systems including a receiver unit of a glucose monitoring system. The receiver is configured for communicating with a remote transmitter unit coupled with a glucose sensor. The glucose sensor generates data signals associated with a glucose level. The receiver unit includes a processor, a display, and a memory for storing instructions which, when executed by the processor: access a transmitter key associated with the remote transmitter unit; transmit a command to the remote transmitter unit after verifying the transmitter key; receive communication packets from the remote transmitter unit including a first data segment with data signals indicative of the glucose level and a second data segment with information corresponding to a remaining life of the remote transmitter unit; estimate a remaining life of the remote transmitter unit; process the data signals; and output the estimated remaining life and the processed data signals for display.
