Abstract: A system including a module and an egress passageway is described. The module includes a cooling cells, a heat spreader, and a cover including vents therein. The cooling cells are between the heat spreader and the cover. Each of the cooling cells includes a cooling element configured to draw air in through the plurality of vents and drive air out of an aperture between the heat spreader and the cover at a first flow rate. A stream of hot air having been heated by a heat from a heat-generating structure thermally coupled to the heat spreader is thus provided. The hot air passes through the egress passageway toward an egress. The egress passageway includes at least one inlet through which cool air is drawn at a second flow rate to be mixed with the hot air. The second flow rate is greater than the first flow rate.

Abstract: A broadcasting signal receiving apparatus a method of controlling the same are provided. The broadcasting signal receiving apparatus includes: a signal receiver configured to receive a broadcasting signal including a stream of data for displaying an image; a buffer configured to store the stream; an interface configured to interface the buffer and a storage device including a storage space for reproducing the stream; a controller configured to control the interface to receive storage information about the stream from the buffer, to receive the stream from the buffer based on the received storage information, and to store the stream in the storage device.

Abstract: An apparatus comprising: a display configured to display contents; a user interface configured to designate a part of the contents displayed on the display unit as a scroll lock region; and a controller configured to lock the scroll lock region to not be scrolled, while contents except the scroll lock region is scrollable in response to a scroll operation.

Abstract: A system for evaluating a network having a plurality of domains, each domain embodying a respective topology, includes: (a) at least one gateway unit effecting signal handling between adjacent domains; (b) a plurality of communicating nodes coupled with the at least one gateway unit; and (c) at least one respective edge establishing a respective communication link between adjacent respective communicating nodes. At least one first selected communicating node is a unicast node. At least one second selected communicating node is a multicast node. At least one communicating node is a media node. Each unicast node is configured for handling messages addressed to the unicast node. Each multicast node is connected with at least one media node within a domain. Each media node is configured for handling messages addressed to multicast nodes connected with the media node individually or en masse.

Abstract: A DTMF transmission structure of a W-CDMA WLL system in which a DTMF signal is transmitted and received to and from a switching system through a terminal station and a base station controller, each of the terminal station and the base station controller comprising: an echo canceller for extracting an echo component from a received signal; a DTMF detector for discriminating whether a signal to be transmitted is a DTMF signal and controlling the operation of the echo canceller; an adder for adding the signal to be transmitted and the output of the echo canceller; a VOCODER for coding the output signal of the adder to a bit stream form or decoding the received signal in the bit stream form to an analog signal; an adjusted DTMF detector for detecting a digit component from the output of the VOCODER; a DTMF generator for reproducing a normal DTMF signal according to the detected digit component; and a silence generator for generating a silence for a predetermined time immediately after the DTMF signal is reproduce
