Abstract: An optimum combiner that reduces the amount of interference imposed upon a first base station (102) by transmissions of other base stations within the same communication system. Two antennas (112, 114) are used to receive transmissions within a receiving station (110).

Title: Method and system for on-line blind source separation
Inventor: PARRA LUCAS CRISTOBAL
IPC: G10L21/0272
Filed: 2000-09-30
Granted: 2002-06-11
Abstract: A method and apparatus is disclosed for performing blind source separation using convolutive signal decorrelation. For a first embodiment, the method accumulates a length of input signal (mixed signal) that comprises a plurality of independent signals from independent signal sources. The invention then divides the length of input signal into a plurality of T-length periods (windows) and performs a discrete Fourier transform (DFT) on the signal within each T-length period. Thereafter, estimated cross-correlation values are computed using a plurality of the averaged DFT values. A total number of K cross-correlation values are computed, where each of the K values is averaged over N of the T-length periods. Using the cross-correlation values, a gradient descent process computes the coefficients of a FIR filter that will effectively separate the source signals within the input signal. A second embodiment of the invention is directed to on-line processing of the input signal - I.e., processing the signal as soon as it arrives with no storage of the signal data. In particular, an on-line gradient algorithm is provided for application to non-stationary signals and having an adaptive step size in the frequency domain based on second derivatives of the cost function. The on-line separation methodology of this embodiment is characterized as multiple adaptive decorrelation.

The plasma processing device (10) comprises a plasma generator (14) and a processing chamber (52) in communication with the plasma generator (14) such that plasma within the generator may pass into the chamber and react with the surface of a substrate (18) residing therein. The temperature control system (20, 22, 24) comprises (i) a radiant heater assembly (20) for heating the substrate (18), comprising a plurality of radiant heating elements (58) arranged in a plurality of zones (a-n), each zone comprising at least one heating element, and a focused reflector (56) for focusing radiant energy from the heating elements toward the substrate; (ii) a feedback mechanism (24) for providing a substrate temperature feedback signal (25); and (iii) a controller (22), including a P-I-D dosed loop controller (80) and a lamp power controller (90). The P-I-D closed loop controller (80) receives a temperature setpoint signal and the temperature feedback signal and in response thereto independently adjusts a control variable sent to the lamp power controller. The power controller (90) then adjusts the power applied to the plurality of zones of radiant heating elements, independently of the control variable, based on temperature zone maps stored in processor memory. The power controller operates in at least a first ramp state and a second steady state, depending upon the magnitude of difference (Δ) between the temperature setpoint signal and the temperature feedback signal.

Title: Fluid device
Inventor: NISHIO KIYOSHI
IPC: F04B43/00
Filed: 2000-11-23
Granted: 2001-12-01
Abstract: It is an object of the invention to, even in the case where transported liquid containing a sedimenting material such as slurry is used, prevent the sedimenting material from stagnating and collecting in a liquid chamber of a pump. In order to attain the object, a diaphragm (7) that reciprocally moves in an axial direction, such as a diaphragm is disposed in a pump body (1) so as to form a liquid chamber (9) with respect to an inner wall (4a) of the pump body (1). A suction port (18) and a discharge port (19) are disposed in the inner wall (4a). A stroke of sucking liquid from the suction port (18) into the liquid chamber (9), and a stroke of discharging the liquid in the liquid chamber (9) from the discharge port (19) are alternately performed by reciprocal motion of the diaphragm (7). The suction port (18) is disposed in a side face of a protruding tip end portion of a suction check valve (20) which is fixed so as to protrude into the liquid chamber (9) from the inner wall (4a) of the pump body (1), thereby ejecting the sucked liquid toward a circumferential wall (9a) in the liquid chamber (9). Therefore, the sucked liquid ejected from the suction port (18) produces a swirling flow along the circumferential wall (9a) in the liquid chamber (9), and the interior of the liquid chamber (9) is stirred by the swirling flow. Consequently, staying of liquid in the liquid chamber (9) is reduced to enable fresh liquid to be always supplied, and, even in the case where liquid containing a sedimenting material such as slurry is used, the sedimenting material can be prevented from sedimenting and aggregating in the liquid chamber (9).

Because the optical system for information recording and reproduction is combined with the slider, so that the optical head becomes small, unlike an optical head adopting a slider and a large optical system, which are separated from each other. As a result, dynamic characteristics of the optical head improve, thereby reducing the time required for searching for a target track. Thus, the optical head is suitable for a micro information recording and reproducing system.

Title: Solid state image sensing device
Inventor: YOSHIDA TOSHIO
IPC: H04N5/335
Filed: 2001-02-15
Granted: 2002-11-01
Abstract: A CCD area sensor has an effective pixel region A for detecting optical information of a subject and an ineffective pixel region B for detecting optical black. On a light-receiving region 23 in the ineffective pixel region, a light shielding film 30 is provided with an opening portion 40. This enables hydrogen ions to be sufficiently diffused from a passivation film 33 made of a P-SiN film toward a silicon substrate 21 in a hydrogen annealing process even though, the light shielding film 30 is made of a material such as a high-melting point metal of TiW that is hard for, hydrogen ions to penetrate. As a result, interface state densities in a light-receiving region 23 and a transfer channel region 24 are reduced, and a dark-time output voltage of the ineffective pixel region is reduced to be equivalent to that of the effective pixel region. Thus, no difference occurs between the effective pixel region and the ineffective pixel region in terms of the black level.

The drive can abort the current drum action and begin the next drum action in the sequence and, after a predetermined number of overload conditions, can suspend counter-rotating drum operation. The user may be provided with an indication when an overload condition occurs.
