Disclosed is a method and system for estimating an adaptive joint channel in a CDMA system based on TDD. The method includes the steps of a) receiving activity information of a mobile terminal; b) parsing the activity information, and transmitting a midamble sequence to the mobile terminal when a result of the parsing shows that the mobile terminal is in an ON state; c) conducting adaptive joint channel estimation by using the midamble sequence in the mobile terminal; and d) conducting adaptive joint detection by using a channel impulse response of the mobile terminal, obtained as a result of conducting the adaptive joint channel estimation. The method and system decreases the complexity in channel estimation and additionally increases the accuracy of channel estimation by reducing transmission power consumption and eliminating unnecessary interference.

A deposition mask that is placed on a mask frame by a tensile force includes first through nth corrected patterns obtained by correcting first through nth initially designed patterns, which are arranged sequentially in a first direction, a row direction and a column direction in view of the tensile force applied to the deposition mask. Outermost sides of the first through nth corrected patterns include first outermost sides extending in a second direction perpendicular to the first direction and second outermost sides extending in a direction parallel to the first direction. The first outermost sides have a first curvature and are recessed inwardly with respect to the first and the nth initially designed patterns. The second outermost sides have a second curvature and protrude outwardly with respect to the first through nth initially designed patterns.

A deposition mask that includes a mask sheet and a frame to support the perimeter of the mask sheet. The frame includes a contact surface that is attached to the mask sheet, and a non-contact surface that faces and is spaced apart from the mask sheet, the non-contact portion extends from the contact portion, to an opening formed in the center of the frame. The non-contact portion may form an acute angle, with respect to the plane of the mask sheet.

Provided is a beacon scheduling method based on a distributed address assignment scheme that schedules a beacon and minimizes data delay using non-collision of addresses in a network, such as a ZigBee network, that provides a distributed address system. In the method, a time offset Tn between beacon reception from a parent device and beacon transmission of a device in a wireless network system having a tree structure may be obtained from Tn=SD×(1+On×Bd) according to an address of the device determined by a distributed address assignment mechanism to create a beacon transmission schedule, where SD denotes a super-frame duration, On denotes a value for determining which child among sibling devices in the network the device corresponds to, and Bd denotes a maximum number of router devices that a sub-network having a depth d in a tree can have.

Embodiments of the present disclosure provide an organic electroluminescence display device. The display device may include a set of multi-directional spacers that are interposed between the pixels of the display. In one embodiment, the spacers are positioned in both lengthwise and crosswise directions. In another embodiment, the spacers include a first portion that is extends lengthwise between pixels and one or more portions that extend laterally from the first portion between pixels. In yet another embodiment, the spacers include portions that extend in multiple directions between pixels. The spacers may substantially surround each of the pixels and may serve as a boundary, for example, that prevents organic material for one pixel from being incorrectly deposited in another pixel. The spacers can be configured as a support structure, such as, for a metal mask during fabrication of the display device. In addition, the multi-directional aspect of the spacers may be useful in protecting the pixels from damage, such as, when a metal mask is moved during mounting or during fabrication of the display device.
