Inventor: JALALI AHMAD
IPC: H04L12/801
Filed: 2001-07-12
Granted: 2003-08-21
Abstract: Transmitter and receiver units for use in an OFDM communications system and configurable to support multiple types of services. The transmitter unit includes one or more encoders, a symbol mapping element, and a modulator. Each encoder receives and codes a respective channel data stream to generate a corresponding coded data stream. The symbol mapping element receives and maps data from the coded data streams to generate modulation symbol vectors, with each modulation symbol vector including a set of data values used to modulate a set of tones to generate an OFDM symbol. The modulator modulates the modulation symbol vectors to provide a modulated signal suitable for transmission. The data from each coded data stream is mapped to a respective set of one or more ""circuits"". Each circuit can be defined to include a number of tones from a number of OFDM symbols, a number of tones from a single OFDM symbol, all tones from one or more OFDM symbols, or some other combination of tones. The circuits can have equal size or different sizes. Different circuits can be used for full rate data (e.g., active speech) and low rata data (e.g., silence periods).

Title: Overload protection method of motor in servo press machine
Inventor: HATA YUKIO
IPC: B30B15/26
Filed: 2003-01-14
Granted: 2007-01-01
Abstract: The present invention provides an overload protection method of motor in servo press machine, which can prevent the overload abnormality during the automatic operation of servo press machine. In the automatic operation, the accumulated heat (Qn) is calculated based on the detected load current of motor (In) practically measured in the past. When the accumulated heat (Qn) exceeds the threshold value (Qs1), the slider (3) is temporarily stopped at the predetermined position else than the formation region. At this time, after stopping the slider (3) temporarily, and when the load current of motor (In) is above the predetermined value, the slider (3) is raised for a predetermined distance and is temporarily stopped. After the slider is stopped temporarily, the load current of motor is detected again. When the accumulated heat (Qn) calculated based on the detected load current of motor (In) practically measured is less than the second threshold value (Qs2) of the accumulated heat, the temporary stop is released, and the reactivation state is reentered. Also, it can be reactivated after the slider is temporarily stopped for a predetermined period.
