The present invention is related to a statistical multiplexing method and apparatus using a multi-dimensional orthogonal resource hopping multiplexing method in a wired / wireless communication systems where a plurality of communication channels, which are synchronized through a single medium, coexist. The present invention, in order to implement a generalized statistical multiplexing communication system using a multi-dimensional orthogonal resource hopping multiplexing method, comprises a multi-dimensional hopping pattern generator which is located in the primary communication station, a data symbol modulator that modulates data symbols based on the corresponding orthogonal resource hopping pattern generated by said multi-dimensional hopping pattern generator, a collision detector and controller that detects whether a collision occurs or not between the multi-dimensional hopping patterns and compares the consistency of the data symbols toward the secondary communication stations between said collision interval, a transmission power controller that controls the transmission power of the remaining parts excluding the parts where the multi-dimensional hopping patterns collide and the transmission is stopped due to transmitting data symbol inconsistency and compensates for the loss in the average reception energy due to a transmission stoppage.

A method for minimizing the loss of data and ensuring that large delays do not occur during reconfigurations of an uplink transmission time interval (TTI) length of a WCDMA High Speed Packet Uplink Access (HSUPA) air interface, wherein the reconfiguration of an uplink TTI length is delayed until all pending retransmissions are successfully transmitted or until the maximum number of transmissions is reached. The transmission of new packets during this time period is prevented. However, pending retransmissions are allowed to occur. After the UE has received an ACK / NACK for each HARQ process, or until the specific maximum number of re-transmissions is reached, the UE starts transmitting with a new uplink TTI length.

An ultrasound apparatus and a method of emitting plane wave are provided. The ultrasound apparatus includes an ultrasound probe, a transceiver circuit, a switch module and a processor. The ultrasound probe has a 1st to a Mth transducer elements for respectively emitting ultrasound beams to form the plane wave, and the transceiver circuit has a 1st to a Nth transceiving channels. M, N are positive integers, and M is a multiple of N. During a scanning period, the processor controls the switch module to initially and respectively connect the 1st-Nth transceiving channels to the 1st-Nth transducer elements, such that the 1st-Nth transducer elements successively emit the ultrasound beams. After the ultrasound beam is emitted by the Nth transducer element, the processor controls the switch module to respectively connect the 1st-Nth transceiving channels to the (N+1)th-(2N)th transducer elements, such that the (N+1)th-(2N)th transducer elements successively emit the ultrasound beams.

A magneto-electric-induction conversion system of a wireless input device includes an emitter and a receiver. A plurality of serially-connected resonant circuits, arranged side by side, makes resonance, so transmission energy is enhanced. An electromagnetic wave is transmitted via an inductive antenna, then received and converted by predetermined parallel-connected resonant circuits into an available power source, so that the energy is effectively delivered.

A display panel has a display area, a first wiring area, and a second wiring area, in which the display area is adjacent to the first and second wiring areas.
