Title: Spatial processing with steering matrix for pseudo-random transmit steering in multi-antenna communication system
Inventor: WALLACE MARK S
IPC: H04B7/04
Filed: 2010-05-26
Abstract: <P>PROBLEM TO BE SOLVED: To generate steering matrices for pseudo-random transmit steering (PRTS) to be used for spatial processing.  <P>SOLUTION: The steering matrices can be generated by selecting a base matrix which can be a Walsh matrix or a Fourier matrix. Different combinations of scalars are then selected, with each combination including at least one scalar for at least one row of the base matrix. Each scalar is a real or complex value (e.g., +1,-1,+j or -j). Different steering matrices are generated by multiplying the base matrix by each of the different combinations of scalars. The steering matrices are different permutations of the base matrix.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Title: Piezoelectric actuator apparatus and ink jet head
Inventor: YAMASHITA TORU
IPC: B41J2/045
Filed: 2010-05-31
Abstract: PROBLEM TO BE SOLVED: To specify a piezoelectric element generating dielectric voltage failure, and to securely prevent short circuit between electrodes of the element.SOLUTION: A comparator 48 of a driver IC 47 compares supply voltage (VDD) from a power source when voltage is impressed to only one activity section of a piezoelectric actuator 7 with a predetermined reference value. Based on the comparison result, a determination circuit 49 of a control device 8 determines whether the dielectric voltage failure relevant to each of a plurality of activity sections is generated or not. When the determination circuit 49 determines that the failure relevant to one activity section is generated, the determination circuit 49 determines whether the failure of the one activity section is a failure of a single body or a failure between adjacent activity sections, based on determination whether failure is generated in the adjacent activity sections or not. The driver IC 47 decides impressed voltage so as to prevent short circuit between electrodes relevant to the activity section where failure is generated according to the determination result.

Abstract: PROBLEM TO BE SOLVED: To provide a sheet shutter for which an antistatic measure or a static electricity removal measure is taken for a sheet.SOLUTION: In a sheet 3 of the sheet shutter, discharge lines 20 comprising a conductive line or tape are disposed. The discharge lines 20 comprise one vertical line 21 and three horizontal lines 22A, 22B and 22C. Since an upper end part 3b of the sheet 3 where an upper end part of the vertical line 21 is disposed is wound around a rotor pipe 6 at all times, the line 21 is conducted to the rotor pipe 6. Since the rotor pipe 6 is practically grounded, it is considered that the discharge line 20 is grounded. Thus, a potential charged to the sheet 3 is promptly released through the discharge line 30 and the rotor pipe 6 and the charging of the sheet 3 is prevented.
