摘要:
Disclosed is a handle structure formed on the rear surface of the portable terminal, which comprises: fixing holes parallel formed in an shape on said rear surface; and a belt-type handle of which both ends are inserted and fixed into said fixing holes. Said belt-type handle comprises: a fixing part, folded parts, and a human body contact part extending from and connecting both folded parts. Said human body contact part has a curved shape the width of which is narrow at the center and gradually increases toward both folded parts. Each of said folded parts has a cylindrical shape, and a silicone layer is pressed and attached to the inner surfaces of the folded parts. Said silicone layer extends to surround a hole jaw within each of the fixing holes.

A control apparatus for use in wireless communications includes an antenna unit having antennas, the number of the antennas being equal to a maximum allowable number of connections in a specific frequency band; and a controller for receiving a connection request signal from each terminal attempting to connect to the control apparatus via the antenna unit, and transmitting and receiving a data signal to and from each terminal connected to the control apparatus by using a multiple-input-multiple-output scheme. The controller transmit and receive the data signal to and from each terminal connected to the control apparatus by obtaining a signal value of each antenna based on a predicted channel matrix and the number and types of terminals connected to the control apparatus via the antenna and separating the data signal for each terminal from the signal value according to the multiple-input-multiple-output scheme.

Provided is an apparatus and method for performing a wideband short-range wireless communication using a directional antenna in a millimeter wave band, and the method for wideband short-range wireless communication according to an embodiment may determine a change of a relay operation type based on a link quality between a source node and a relay node, a link quality between the relay node and the destination node, and a link quality between the source node and the destination node, transmit a relay operation change (ROC) request message in response to a determination of the change of the relay operation type, and receive an ROC response message corresponding to the ROC request message.
摘要:
The present invention provides a wireless communication method used for transmitting and receiving a relay in a wireless local area network system. The wireless local area network system according to an embodiment of the present invention relates to a wireless communication method of setting a relay link through a relay and setting a transmission time point at which a data frame is transmitted in a source device by recognizing a propagation delay between devices, and the like when an operation mode of the set relay corresponds to a cooperating mode.

An airbag apparatus may include a fastening unit mounted to a portion of a vehicle, a multi-ply airbag cushion fastened to the fastening unit, the multi-ply airbag cushion being formed by overlapping airbag cushion sheets on each other to form a multi-ply structure, and an inflator to provide gas to the airbag cushion sheets of the multi-ply airbag cushion.
摘要:
The present invention relates to a filament for an infrared lamp used as a heater and a method of manufacturing the same. The method of fabricating the filament includes cutting a thin graphite plate into a thin graphite plate strip of a predetermined size, integrally adhering two sheets of the thin graphite plate strips using heat, primarily heating and plasticizing the integrally adhered graphite plate strips within an inert gas, coating a silicon-series coating solution on the primarily heated and plasticized graphite plate strips and naturally drying the graphite plate strips, and heating and plasticizing the naturally dried graphite plate strips using an identical process to the primary plasticity process and then naturally cooling the heated and plasticized graphite plate strips.

An external airbag system of a vehicle may include an airbag housing that is disposed behind a bumper of the vehicle and is allowed to slide straight in a forward direction, an airbag cushion that is disposed inside the airbag housing, a sliding device that moves the airbag housing in a forward direction, and an airbag controller that controls the airbag cushion and the sliding device according to information of sensing device.
摘要:
Provided is a method and apparatus for selecting a channel in a wideband high frequency wireless system. The channel selection method may include: generating a channel scanning request frame that includes a channel bitmap, wherein the channel bitmap denotes information regarding a channel to be scanned by a neighboring device; transmitting the channel scanning request frame to the neighboring device; receiving a channel scanning response frame corresponding to the channel scanning request frame; and selecting a channel for a communication with the neighboring device, based on the channel scanning response frame.
