There are provided a unicast type network apparatus having reduced power consumption, and a data transmission and reception method thereof. The unicast type network apparatus includes: a first device allowing link quality information between the first device and a reception side to be included in a data frame and then transmitting the data frame to the reception side, at the time of transmission of data; and a second device receiving the data frame from the first device and allowing link quality information between the second device and the first device to be included in an acknowledge frame in response to the data frame and then transmitting the acknowledge frame to the first device, when the link quality information is included in the data frame.

There is provided a network apparatus in which a contention free period is fixed at a relatively maximum size and guaranteed time slots are varied in the fixed contention free period to allocate remaining time slots of the contention free period to data transmissions of terminals according to priority. There is provided a network apparatus for accessing a channel in a contention free period, the method including: a coordinator fixing a contention free period within a frame to have a preset size and setting and allocating guaranteed time slots (GTSs) in the fixed contention free period according to request; and a terminal group having at least one terminal, forming a network with the coordinator, requesting guaranteed time slots from the coordinator, and transmitting data in allocated guaranteed time slots.
摘要:
A host device, a point of deployment (POD), and a method for recognizing an operation mode are disclosed. The host device interfaces with a point of deployment (POD), and includes an interface unit and a controller. The interface unit includes CD1#, CD2#, VS1#, VS2#, VPP1, VPP2, and IPDET ports. The controller outputs a mode confirmation signal to the POD via the IPDET port, and identifies that the POD supports an Internet Protocol (IP) Card M-Mode when the mode confirmation signal has been applied to the VS1# and VS2# ports.

There is provided a channel access method in which a channel access method in a wireless network in which a channel access opportunity is provided to high priority traffic for each super-frame. The channel access method includes: setting parameter values required for channel access; setting a channel access time to be equal to a size of a contention access period (CAP); and accessing a channel to be used by resetting the channel access time to be equal to the size of the CAP when traffic to be transmitted is traffic having a preset high priority in a case in which the channel is not in an idle state.

A projection type display apparatus is capable of significantly reducing operational noise of a color wheel. The projection type display apparatus includes a color wheel, a color wheel assembly in which the color wheel is installed, and a noise damping section which changes air flow caused by a rotation of the color wheel so as to reduce the noise.

The present invention provides a hybrid material comprised of an active component for raw materials for cosmetics and a layered metal hydroxide, showing good stability, low toxicity, low irritation, good sustained release and good dispersibility. The present invention provides a method for preparing the hybrid material, using the coprecipitation method, the ion-exchange method or the adsorption method, depending on properties of the active component for raw materials for cosmetics. The method may further comprise a step of coating the surface of the hybrid material after preparation of the hybrid material. The present invention provides cosmectics comprising the above hybrid material.
摘要:
A host device, POD (point of deployment) and a method of identifying an operation mode are disclosed, by which data received via internet can be processed. The present invention includes an interface unit including CD#1, CD#2 , VS1#, VS2#, VPP1, VPP2 and IPDET ports and a controller controlling a mode confirmation signal to be outputted to the POD via the IPDET port, the controller recognizing that the POD supports an IP (internet protocol) card M-mode if the outputted mode confirmation signal is inputted to the VS1# port.
