In a mobile communications system, a plurality of base stations may receive the same signal, whereby the "best" reception may be determined. The plurality of received digital signals are combined to form a majority signal. Each of the received digital signals is compared to the majority signal to estimate the bit-error-rate (BER) of each received signal. If the difference between the highest and l...

The invention relates to a brake cylinder suitable for a hydraulic vehicle brake system, having at least one brake chamber and a brake booster, actuatable by a piston rod, with a brake valve assembly that has an inlet and an outlet for power brake fluid and communicates with a pressure chamber of the brake booster. The pressure chamber is located in a longitudinally bored housing section and is de...

A composite mixture of two materials, at least one of which includes a metal or metal alloy, is formed by causing each material to flow in a molten or slurry state through inlet channels (13) into a mixing region (17) where they impinge on each other. The resulting composite mixture flows from the mixing region (17) into an outlet passage (16) for subsequent forming into a continuous casting, disc...

This invention provides improved seating for vehicles having cramped space for operators. A tubular frame (12) is disposed to the periphery of backrest and seat members (13), (14). The backrest slides and pivots with respect to the frame and is pivotally attached to the seat.
