A method for validating positional data in vehicle surveillance applications wherein vehicles transmit positional data indicating their own position to surrounding vehicles using a data link over which a transmission is initiated at a given transmission point in time that is known by all users of the data link. A signal transmitted from a radio source over the data link is received at a receiving unit. The signal carries positional data indicating an alleged position of a vehicle. The distance between the receiving unit and the radio source is estimated based on the time of flight and the propagation velocity of the received signal. The time of flight is determined based on the time elapsed from the transmission point in time of the signal to the time of reception of at least a first part of the signal. A deviation value is determined. The deviation value indicates the difference between the distance to the position of a vehicle according to the received positional data and the estimated distance to the radio source.

A loop delay control circuit is provided between a comparator and a power switch stage. When the amplitude of an input signal is especially high, the loop delay control circuit secures an oscillation threshold value by setting a delay amount at a low value. On the other hand, when the amplitude of the input signal is not so high, the loop delay control circuit reduces an average switching rate by increasing the delay amount, but does not reduce the oscillation threshold value. This makes it possible to provide a delta-sigma modulator allowing realization of both (i) a high oscillation threshold value, i.e., high output power, and (ii) high power efficiency.

A process for floating fine particles containing metal values of an iron-bearing sulphide mineral ore including the steps of conditioning the aqueous pulp of ore at a pH of between about 7 and about 10 with a reducing agent which is preferably oxy-sulphur compound which dissociates to form oxy-sulphur ions having the general formula:where n is greater than 1; y is greater than 2; and z is the valance of the ion.A suitable collector is then added to the conditioned aqueous pulp to further condition the pulp and the pulp potential of the pulp raised to a sufficient level for the collector to adsorb onto the sulphide mineral ore. Gas is then bubbled through the aqueous pulp to subject the pulp to froth flotation. The froth from the flotation process is recovered to produce a concentrate of fine sulphide mineral and other metal values.By conditioning the aqueous pulp at a pulp potential which dissolves the iron hydroxide film from the surface of the metal sulphide inclusions in the ore and subjecting the ore to froth flotation at a suitable pulp potential before the iron hydroxide can reform, the recovery of metal values in the fine ores can be greatly enhanced.

A motor drives a window glass of a door of a vehicle in an opening direction and a closing direction. A rotation sensing device outputs a pulse signal in response to rotation of the motor. A controller senses pinching of an object by the window glass based on the rotational speed signal.

The controller senses start of the pinching based on the rotational speed difference. When an amount of change in the rotational speed since the time of sensing the start of the pinching exceeds a pinching determining threshold value, the controller confirm the pinching of the object.
