An apparatus for modifying aircraft cabin airflow includes a redirector configured to receive an airflow from an inlet of an aircraft cabin. The redirector is configured to downwardly redirect at least a portion of the airflow. In one embodiment, the redirector includes a dividing portion configured to be oriented generally parallel to the airflow received at the redirector from the cabin inlet, and further includes a redirecting portion configured to be oriented in a generally downward direction. In another embodiment, the redirector includes an elongated protrusion configured to be positioned on a ceiling of the aircraft cabin.

Methods and apparatus for a Wireless Terminal (WT) to convey uplink traffic information, e.g., uplink channel resource requests, to a Base Station (BS) are described. Uplink transmission resources are requested for data corresponding to different priority levels. The WT keeps track of the BS's understanding of WT traffic through the use of a first queue which keeps track of the BS's estimate of WT's uplink queue status for different priority levels by following the same procedure the BS uses to update its estimate of WT queue status. The WT uses this tracked information along with actual traffic information it maintains in a second set of queue information to form uplink traffic channel requests to be transmitted to the BS. Methods used by the BS to interpret uplink traffic channel requests from WTs are also described. The BS maintains its own queue of requests and corresponding priority information for individual WTs.

Disclosed herein is a dynamic update cube and hybrid query search method for range-sum queries. The present invention relates to a hybrid query search method, which provides a precise answer or an approximate answer with respect to On-Line Analytic Processing (OLAP) queries by using a delta (Δ)-tree, which has a multidimensional index structure and a prefix-sum cube, so as to effectively support range-sum queries widely used in opinion decisions in enterprises. In the dynamic update cube and hybrid query search method for range-sum queries, a prefixed-sum cube is dense and the dynamic update cube is sparse, such that whenever a data cube changes, the prefixed sum cube is not directly updated and instead, the changes of the data cube are stored in a Δ-Tree and the Δ-Tree is managed.

An ultrasonic wave transmitting and receiving unit includes: a piezoelectric member supporting plate; an acoustic matching member fixed to one surface of the piezoelectric member supporting plate; a piezoelectric member fixed to the other surface. Moreover, the ultrasonic wave transmitting and receiving unit includes: an insulating vibration suppressing member integrally formed in such a manner as to cover the piezoelectric member and the piezoelectric member supporting plate, wherein the insulating vibration suppressing member has a hole reaching the piezoelectric member supporting plate.

The invention relates to a method for reducing visual artefacts in a digital image, which is coded by blocks (B1, B2, B3, B4) and then decoded. In the method filtering is performed to reduce visual artefacts due to a boundary (R12, R13, R24, R34) between a current block and an adjacent block (B1, B2, B3, B4). The filtering is performed after the current block (B1, B2, B3, B4) is decoded and there is a boundary available for filtering between the current block and a previously decoded block.
