Title: Process and plant for the recovery of materials from sport equipment
Inventor: ALAVI KAMAL
IPC: B29K105/20
Filed: 1993-10-27
Abstract: Abstract The disclosed process produces and recovers fractions of materials, containing most of the original weight of the treated material, with a sufficient degree of separation. Most of the material thus recovered is suitable for industrial reuse.          The process is particularly suitable for sport equipment made mainly of plastic and/or wood in conjunction with metal compo-nents, such as skis, ski boots, snowboards, skateboards, and safety helmets. The steps of the process comprise mechanical shredding and several stages of mechanical and physical sepa-ration, but no incineration. The process is environmentally acceptable and easy to operate. A suitable plant that consists mainly of shredding units and various types of separator units can preferably be made as a mobile assembly and, for example, installed in a road vehicle.

Title: Compensation for multi-path interference using pilot symbols
Inventor: MARCHETTO ROBERT F
IPC: H04B7/005
Filed: 1993-11-23
Abstract: COMPENSATION FOR MULTI-PATH INTERFERENCE USING PILOT             SYMBOLS Abstract of the Disclosure A method and apparatus for compensating fading and interference in a radio signal. A plurality of pilot symbols are appended to a plurality of data symbols to form successive frames that are modulated at a transmitter. The transmitted modulated signal is subject to loss of data due to simple fading and multi-path and simulcast interference. The received signals are demodulated by a receiver and processed to provide a data signal comprising the data symbols and a pilot signal comprising the pilot symbols. The data signal is delayed for sufficient time to enable channel impulse response estimates to be made of successive blocks of pilot symbols, preferably using pilot symbol blocks that both precede and follow the data symbols in the frame being processed. The channel impulse response estimates for blocks of pilot symbols are buffered and used by an interpolator to determine an interpolated channel impulse response estimate for each data symbol as a function of both the pilot symbols and of predefined channel characteristics. The interpolated channel impulse response estimates are applied to successive data symbols in the delayed data signal, enabling the data to be decoded, compensating for fading and interference. Interpolation using predefined channel characteristics based on worst case conditions substantially improves the bit error rate (BER) for the data recovered, compared to the prior art.

Title: Code-division multiple-access mobile telephone system
Inventor: ASANO NOBUO
IPC: H04W76/00
Filed: 1994-07-07
Abstract: In an automobile on-board and/or portable telephone system capable of increasing the capacity of subscribers easily on the basis of changing of information transmission bit rate, spread codes obtained by multiplying orthogonal spread codes (m in number) by a pseudo-random noise series are assigned to individual channels in the same cell in such a manner that the orthogonal spread codes are multiplied by some types of pseudo-random noise series having different phases, thereby making it possible to maintain the number of channels in the same cell at a value which is a multiple of the number of the orthogonal spread codes. Through this, in the case where the transmission bit rate is halved as compared to the presently existing rate in the future, assignment of spread codes which are increased in number to as large a value as necessary can be achieved and the subscriber's capacity can be increased within a range in which the necessary quality can be maintained even when link paths for m or more channels are set up in one cell from the viewpoint of SIR.
