A method for processing measurements, acquired by a measurement sensor at different measurement times, involves the measurement sensor being integrated into a connected device that is worn/borne by a user and configured to connect to a wireless communication network. The measurement sensor is configured to acquire, at each measurement time, a measurement representative of a movements of, or a physiological characteristic of, the user. The measurement sensor is parameterized by various parameters, the value of each parameter being encoded in a register. Measurements are acquired by the measurement sensor at various measurement times to form a sequence of measurements. Data, established from the sequence of measurements, is transmitted to an interpreting application programmed to estimate, from the transmitted data, a user state selected from a plurality of predetermined states. The method also includes, before or during the measurements acquisition, a verification of the parameters of the measurement sensor.

According to an aspect, there is provided a method of sending a message to a subject, the method comprising obtaining (30; 502) measurements of one or more physiological characteristics of a subject over time; determining (32; 504) a psychological state of the subject for a plurality of time periods from the measurements; and in the event that it is determined that the subject is in a psychological state of interest in a first time period, sending (34; 514) a message to the subject in a time period subsequent to the first time period in which it is determined that the subject is not in the psychological state of interest.

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.
