Patent NO-337159-B1 (NO)
Inventor: SPORER THOMAS
IPC: G10L19/00
Filed: 2006-04-28
Abstract: When processing a signal having a sequence of discrete values, wherein there is a first frequency range, in which the signal has a high energy, and wherein there is a second frequency range, in which the signal has a low energy, the sequence of discrete values is first manipulated to obtain a sequence of manipulated values, so that at least one of the manipulated values is non-integer. Then the sequence of manipulated values is rounded to obtain a sequence of manipulated values. The rounding is formed to effect a spectral shaping of a generated rounding error so that a spectrally shaped rounding error has a higher energy in the first frequency range than in the second frequency range. By spectrally shaping the rounding error so that the rounding error does not have any energy either in the storage areas where there is no signal energy, an especially efficient coding is obtained particularly in connection with a lossless coding context.
Patent NO-325878-B1 (NO)
Inventor: STRAUME INGVALD
IPC: F03B13/14
Filed: 2007-04-17
Abstract: A device for a wave-power plant includes a self-tightening winch with a winch wire. The winch wire is connected to a wave-power-operated absorption element at one end and to a cable drum of the self-tightening winch at the other end. The cable drum is connected via a transmission system to an outgoing axle which is further connected to an energy-storing restructuring machinery. Movement of the absorption element results in rotation of the cable drum and transmission of mechanical energy from the cable drum to the rotating outgoing axle and to the restructuring machinery. The transmission system includes a slip clutch connected to the outgoing axle, which protects the components in the wave-power plant, particularly the components in the restructuring machinery, against overload in the event of large wave amplitude. The engagement of the slip clutch varies depending on the rotational speed or torque of the outgoing axel, thereby providing a maximum threshold for how great an amount of energy per time unit can be transmitted to the outgoing axle and to the energy-storing restructuring machinery.
