Title: Mimo system with multiple spatial multiplexing modes and method using the same
Inventor: J RODNEY WALTON
IPC: H04B7/04
Filed: 2003-10-24
Granted: 2010-12-21
Abstract: A MIMO system supports multiple spatial multiplexing modes for improved performance and greater flexibility. These modes may include (1) a single-user steered mode that transmits multiple data streams on orthogonal spatial channels to a single receiver, (2) a single-user non-steered mode that transmits multiple data streams from multiple antennas to a single receiver without spatial processing at a transmitter, (3) a multi-user steered mode that transmits multiple data streams simultaneously to multiple receivers with spatial processing at a transmitter, and (4) a multi-user non-steered mode that transmits multiple data streams from multiple antennas (co-located or non co-located) without spatial processing at the transmitter(s) to receiver(s) having multiple antennas.; For each set of user terminal(s) selected for data transmission on the downlink and/or uplink, a spatial multiplexing mode is selected for the user terminal set from among the multiple spatial multiplexing modes supported by the system.

Title: Microwave filter disposed on the circuit board of wireless communication product
Inventor: YANG GUEI-JI
IPC: H03H9/46
Filed: 2003-10-28
Granted: 2004-11-21
Abstract: The present invention is related to a microwave filter disposed on the circuit board of wireless communication product. The manufacturing technique of printed circuit board is applied in the microwave filter. When manufacturing the circuit board of wireless communication products, the microwave circuits, such as one input terminal, one double-frequency resonant cavity and one output terminal, included in the microwave filter are directly disposed on the circuit board, so as to effectively suppress the double-frequency and even higher order harmonic wave noise generated due to the nonlinear distortion of power amplifier in the wireless communication products under the state of having no need of using extra high-frequency filter. Thus, it is capable of greatly lowering the manufacturing cost of wireless communication products and effectively reducing the generated electromagnetic (EM) wave interference.

Title: Input/output buffer
Inventor: CHEN SHENG-HUA
IPC: H03K19/0185
Filed: 2004-01-20
Granted: 2004-11-21
Abstract: An input/output buffer. An input/output circuit is composed of a first PMOS transistor and a first NMOS transistor, has an I/O port coupled to an I/O pad, and a N-well region. An N-well control circuit controls the voltage level at the N-well region of the first PMOS transistor according to input signals at the I/O pad. A P-gate control circuit receives a second gate control signal and outputs to the gate of the first PMOS transistor. The P-gate control circuit is composed of a transmission gate and a third PMOS transistor. The transmission gate and the third PMOS transistor do not have to follow the design rule for ESD, and the wafer area required for the P-gate control circuit can be decreased because the P-gate control circuit is not directly connected to the I/O pad.

Title: System topologies for optimum capacity transmission over wireless local area networks
Inventor: TERRY JOHN
IPC: H04W74/02
Filed: 2004-04-02
Granted: 2006-02-01
Abstract: An inventive method provides optimum topology for a multi-antenna system dedicated to higher throughput/capacity by bundling the point coordination function (PCF) operation in infrastructure mode of the current and/or enhanced IEEE MAC with PHY specifications that employ some form of coherent weighting based on CSI at the transmitter in conjunction with the corresponding optimum receiver detection based on CSI. Specifically, CSI is measured from a control message, so data messages and control messages are separated. In the contention period of IEEE 802.11, the RTS/CTS exchange is used for CSI and the data message is sent following the CTS message. In the contention free period, a poll by the PC is separated from a data frame, which gives the polled station the first opportunity to send a data message. The change in topology results in various changes to the frame exchange format in the CFP for various scenarios of data and control messages to be exchanged.

Title: Veneer dryer
Inventor: ROOS GOTTFRIED
IPC: F26B19/00
Filed: 2004-08-18
Granted: 2006-11-01
Abstract: The problem with known veneer dryers is that the individual drying zones cannot be separated distinctly. The optimal process conditions, which change during the drying process, cannot therefore be adjusted as required, as this leads to short-circuit currents between the drying zones. Thus, a novel veneer dryer is provided, in which the drying parameters can be optimally adjusted zone by zone. To achieve this, the drying zones (2), (3), (4) are arranged one above the other on horizontal planes and are thus effectively separated from one another.

Title: Structure of anti-reverse float screw
Inventor: CHENG MIN-SHIEN
IPC: F16B39/24
Filed: 2004-12-10
Granted: 2006-01-21
Abstract: A structure of anti-reverse float screw includes a screw installed inside a rotation cylinder. A float cylinder is fit over the screw. Furthermore, the float cylinder is received in the rotation cylinder. Also, a spring is installed between the rotation cylinder and the float cylinder. The invented structure is mainly characterized in that a stop ring is fastened inside the rotation cylinder, and the screw is provided with a ring equipped with anti-reverse teeth. Rotation of the rotation cylinder enables the stop ring to advance into the ring with anti-reverse teeth to push the screw for a forward rotation. When the rotation cylinder is rotated in a reverse direction, the stop ring does not advance into the ring with anti-reverse teeth so that the screw can not be withdrawn by a reverse rotation. Thus, the float screw is prevented from unintentional detachment.

The cold rolled steel sheet comprises 0.003% or less of C, 0.003 to 0.03% of S, 0.01 to 0.1% of Al, 0.02% or less of N, 0.2% or less of P, at least one of 0.03 to 0.2% of Mn and 0.005 to 0.2% of Cu, and a balance of Fe and other unavoidable impurities in terms of weight%. When the steel sheet comprises one of Mn and Cu, the composition of Mn, Cu, and S satisfies at least one relationship: 0.58*Mn/S <= 10 and 1 <= 0.5*Cu/S <= 10, and when the steel sheet comprises both Mn and Cu, the composition of Mn, Cu, and S satisfies the relationship: Mn+Cu <= 0.3 and 2 <= 0.5*(Mn+Cu)/S <= 20. Participates of MnS, CuS, and (Mn, Cu)S have an average size of 0.2 mum or less. Since carbon content in a solid solution state in a crystal grain is controlled by fine precipitates of MnS, CuS, or (Mn, Cu)S, the steel sheet has enhanced aging resistance and formability. And has excellent yield strength and strength-ductility.
