| The flight of an aircraft is characterized in terms of Earth-based reference system data for a first position and a second position of the aircraft that are separated by a time increment. A centripetal acceleration of the aircraft is determined based on the Earth-based reference system data for the positions in conjunction with the time increment. A rate of rotation is established corresponding to the time increment in an aircraft-based reference system. Aircraft airspeed is determined based on the centripetal acceleration and the rate of rotation. A turn can be detected as characterized by a change in track angle from a prior GPS packet compared to a new packet. Aircraft turns can be detected based on a change in track angle in GPS packets. Compensation can be applied to a gyro based on centripetal acceleration such that the gyro more accurately responds to the Earth gravity axis. | ||||||

| A system for monitoring the service life of an HVAC air filter is disclosed and includes an airflow sensor that is positioned in an HVAC duct in relatively close proximity to the air filter. The airflow sensor output is sent to a processor that is pre-programmed with a filter evaluation algorithm. Each time the HVAC blower is activated begins a new duty cycle during which airflow signals are generated are sampled by the processor/algorithm. Selected sampled values are averaged to calculate a peak airflow velocity, Vpeak, for each duty cycle. The peak airflow velocity, Vpeak, is then compared to a base reference, Vreference, to determine whether the air filter requires service/replacement. The value of the base reference, Vreference, can be established during an initializing procedure and thereafter updated using the peak airflow velocity, Vpeak. | ||||||

| A fountain (50) comprises a supply of water under pressure, a primary fluidic diverter (10) having an input (12) for said supply, and first and second outputs (16a, b) diverging from said input. Two control ports (20a, b) are provided with control flow to direct input flow to one or other of the two outputs that lead to the two inputs of a vortex amplifier (40). This comprises a vortex chamber (54), a radial port (50), a vortex inducing port (60) and an axial output port (58). One (16a) of the diverter outputs is connected to the vortex inducing port, the other (16b) to the radial port, so that supply to said axial output port is modulated by formation of a vortex in the chamber when flow is to the vortex inducing port. The axial port leads to a nozzle whereby a vortex spray or axial jet is produced, depending on which diverter output (16a, b) is active. A wind detector (100) has a vertical jet (102) and a catcher (104) which fails to catch water from the jet in high wind conditions. The catcher feeds the control port (20a) of a diverter 101, or such other pressure or flow detector as may be convenient. A fountain array of elements may comprise a number of diverters, the outputs of which have branches supplying the control ports of others in the array, whereby internal control is provided. | ||||||
