Abstract

This present disclosure describes a computer-implemented method for updating a plurality of parameters on a medical inhaler sensor via a wireless connection by a client device. The client device stores the plurality of parameters for the medical inhaler sensor on the client device. The client device updates one or more parameters of the plurality of parameters on the client device. The client device receives a plurality of periodic chirps from the medical inhaler sensor, and can establish the wireless connection with the medical inhaler sensor in in response to having received a chirp. Through the wireless connection, the client device transmits the updated one or more parameters of the plurality of parameters to the medical inhaler sensor.

Core Innovation

The disclosed medicament-device sensing analytics system includes a medicament inhaler sensor and a client device that communicate using Bluetooth Low Energy. To reduce wireless connection latency, the medicament inhaler sensor periodically broadcasts low-power "chirps" that indicate readiness to pair, enabling the client device to establish a wireless connection quickly.

After the client device receives the readiness indication, the system receives event records describing medicament dispensing recorded by the medical inhaler sensor. The client device transmits an echo of a first event record back to the medical inhaler sensor, then receives a second event record at the client device, and determines whether the second event record is a null event record.

A null event record is used to confirm that the first event record is the most recent recording of medicament dispensing by the medical inhaler. Responsive to determining that the received event record is a null event record, the system terminates the wireless connection, and the disclosure describes extensions where additional event records are checked in sequence using null-event determination logic.

Claims Coverage

The independent claims are directed to a computer-implemented method, a non-transitory computer-readable storage medium, and a system, each centered on ping-based connection establishment, event-record exchange using echoes, and null-event determination to confirm the most recent medicament dispensing before terminating the wireless connection. Across the independent claims, the inventive features can be summarized as a ping-to-connection workflow, echoing of event records, and null-event-based wireless termination, with dependent claims refining wireless technology, ping periodicity, event-record contents, and echo matching/continued exchange behavior.

Across the independent claims, the core coverage is an exchange protocol in which a client device receives a ping, establishes a wireless connection to a medical inhaler sensor, receives and echoes event records, determines whether subsequent received event records are null event records confirming the most recent medicament dispensing, and terminates the wireless connection in response to the null-event determination.
