Abstract: The invention relates to antibodies such as anti-C1 s antibodies, pharmaceutical compositions comprising the same, and methods of using the same. The invention provides antibodies that comprise an antigen-binding region and an antibody constant region, have a displacement function such that the antibody binds to C1qrs complex and promotes dissociation of C1q from C1qrs complex and/or a blocking function such that the antibody binds to C1r2s2 and inhibits the binding of C1q to C1r2s2, and bind to C1s in a pH-dependent manner. The invention also provides pharmaceutical compositions comprising any one of the antibodies, and methods of treating an individual having a complement-mediated disease or disorder, or preventing an individual potentially having a complement-mediated disease or disorder, comprising administering any one of the antibodies to the individual.

Abstract: A channel-estimating apparatus according to the present invention, including: an input unit (2) operable to receive several pieces of channel information (5) from a plurality of receivers (10), (11), in which the plurality of receivers (10), (11) are operable to perform MIMO communication through a plurality of channels; an estimating unit (3) operable to collectively estimate statuses of the plurality of channels in accordance with the several pieces of channel information (5) received by the input unit (2), whereby estimation results (6) are generated; and an output unit (4) operable to feed the estimation results (6) into the plurality of receivers (10), (11).

Abstract: A card device to be inserted into a slot of an electronic apparatus having an electronic apparatus ground and electrically connected to this electronic apparatus, including a single antenna provided on a carrier, a card ground which is disposed on the carrier and electrically connected to the antenna, and a switch for carrying out, at a high frequency, a connection/disconnection of the card ground to/from the electronic apparatus ground in a condition where this card device is inserted in the slot.

Abstract: A wireless communication system comprises a base station (4) and terminals (1)-(3). The base station (4) and the terminals (1)-(3) perform a space division multiplex wireless transmission. Each of the base station (4) and the terminals (1)-(3) comprises a multi-beam antenna for a space division multiplex. A beam pattern formed by the multi-beam antenna of the base station (4) is orthogonalized based on transfer function values of a radio-wave-propagation characteristic formed between antenna elements of the multi-beam antenna of the base station (4) and antenna elements of multi-beam antenna of the terminals (1)-(3).

Abstract: Reception level frequency distribution is determined. A frequency correlation bandwidth is determined in accordance with intervals between peaks or dips, or alternatively intervals between intersections wherein the reception level frequency distribution intersects a threshold. At the time of reception start, a training mode period is set up to determine a frequency correlation bandwidth. After the training mode period, signals are received in accordance with the determined frequency correlation bandwidth. The frequency correlation bandwidth is determined with increased precision to avoid a large amount of calculation such as Fourier transform. As a result, the entire diversity reception processing requires a reduced amount of calculation.
