Title: Oversampled channel response identification
Inventor: CHERUBINI GIOVANNI
IPC: G11B20/10
Filed: 2007-11-08
Abstract: Methods, apparatus and computer programs are provided for multiplication-free identification of the impulse response of an oversampled data channel (3). An input (a) comprising a pseudo-random binary sequence of L symbols is supplied to the channel (3) at a symbol rate of 1/T. A channel output (z) is produced by sampling a channel output signal corresponding to the input (a) with a sampling interval Ts = (q/p)T, where q and p are relative prime integers with q < p, and q and L are relative prime integers, p polyphase sequences (P(j)) are produced from the channel output (z) by selecting, for each polyphase sequence (P(j)), every pth sample of the channel output (z), with a phase shift of one sample between successive polyphase sequences (p(j)). A decimated binary sequence (b) is produced by selecting every qth symbol of the channel input (a). Each polyphase sequence (p(j)) is correlated with the decimated binary sequence (b), the two possible binary values being of equal magnitude and opposite sign for the correlation. The correlation results are accumulated to produce a correlated output sequence (c(j)) for that polyphase sequence (p(j)). The samples of the correlated output sequences (c(j)) are then interleaved in phase order of the corresponding polyphase sequences (p(j)) to produce the impulse response of the channel. ® KIPO & WIPO 2009

Title: Clothing with crotch for exercise
Inventor: FUKUYO CHIZURU
IPC: A41D1/08
Filed: 2007-09-12
Abstract: Clothing with crotch for exercise which can enhance performance sufficiently in various exercises with three-dimensional movements such as rotation of the body, rotation/abduction/adduction of both legs. In a wearing state of clothing (1) with crotch for exercise, fastening force by a first fastening portion (21) acts on a muscle group existing on the periphery of a greater trochanter to permit the clothing (1) to be supported so as to widen the movable region of pelvic arch. In contrast, on the inside of the annular first fastening portion (21), the interval of a first line (21a) and a second line (21b) is widened gradually as the position A of the greater trochanter is approached thus forming a side hole (24). By the formation of such a side hole (24), direct oppression of the greater trochanter of a wearer by the first fastening portion (21) is avoided. In the clothing (1) with crotch for exercise, performance of various exercises can thereby be enhanced effectively by securing support of a muscle group around the greater trochanter by the first fastening portion (21), and flexibility of the pelvic band by the side hole (24).
