A firearm () includes a detection system () suitable to detect a configuration change of the firearm from an initial configuration. The detection system () includes a detection device (), on the slide () suitable to be moved, starting from an initial position, to a detection position in which the detection device () detects a configuration change of the firearm. An idler device () on the slide () engages with the detection device () which moves the idler device (). The detection device () includes at least one primary sensor element (), a receiver device () on the main body () suitable to receive the information of the configuration change of the firearm from the primary sensor element () and at least a secondary sensor element ().

Firearm with change configuration detection system

An ultrasonic pool occupant sensing device capable of using ultrasonic pulses to analyze the occupancy level of a swimming pool. An ultrasonic transducer sends and receives ultrasonic pulses. A front end electronics has a driver for controlling the transducer, a pre-amplifier, band-pass filter, and amplifier combination for filtering received signals. The digital processing unit contains a timer unit for generating pulses, an AD converter for digitizing received pulses, a signal processor for determining data about the return pulse, and an I/O unit for transmitting data to the central processing unit. The data may be an estimate of the number of people in the sensor range, or it may be data about the return pulse that can be analyzed by the central processing unit.
