20080253302 | NETWORK FORMATION METHOD AND COMMUNICATION APPARATUS - A determination is made as to whether a communication apparatus is a data sender or a data recipient and, based on the results of the determination, it is determined whether the apparatus constructs a network or joins a constructed network. | 10-16-2008 |
20090075594 | COMMUNICATION APPARATUS, COMMUNICATION METHOD, AND COMPUTER PROGRAM FOR CONTROLLING COMMUNICATION APPARATUS - In a system in which a communication adapter installing UPnP is connected to a printer to provide a print service, the communication adapter notifies a device that the printer joins the network or leaves from it, based on determination whether the printer can provide a service. Hence, the present invention can suppress from issuing a service request to a printer which cannot provide the service. | 03-19-2009 |
20090135943 | COMMUNICATION APPARATUS AND CONTROLLING METHOD THEREOF - To determine an appropriate transmission rate more efficiently in communication which uses multiple-input multiple-output technique, a communication apparatus which selects one of a plurality of transmission rates determined by a set of modulation schemes for streams and communicates with an external device using the MIMO technique of performing transmission using a plurality of streams includes a change unit which changes the transmission rate, and a determination unit which determines, based on a transmission power to be allocated to each stream and the modulation scheme of each stream, the transmission rate to be changed by the change unit so as to make the power per bit of each stream at the transmission rate after change remain unchanged or increase. | 05-28-2009 |
20100165964 | WIRELESS COMMUNICATION APPARATUS, A WIRELESS COMMUNICATION METHOD AND A COMPUTER PROGRAM - A wireless communication apparatus that transmits data in certain communication interval to a receiving apparatus, using one or more communication channels among a plurality of adjacent communication channels, is provided. The apparatus includes: a setting unit configured to set the one or more communication channels for transmitting the data; a transmission unit configured to transmit the data using the one or more set communication channels; and a detection unit configured to detect interference with other wireless communication apparatuses, when the transmission unit transmits the data using the one or more set communication channels; wherein the setting unit changes the number of the one or more communication channels based on a time duration that the data transmission has been restrained due to the detected interference, and the communication interval. | 07-01-2010 |
20100189057 | COMMUNICATION CHANNEL DETERMINATION METHOD AND A DETERMINATION APPARATUS - By controlling a plurality of communication apparatuses, when determining the communication channel used by each apparatus, conducting determination of channel allocation priority order of communication apparatuses, based on the extracted load information of the communication apparatus. Based on the determined channel allocation priority order, setting the communication channels as they should be set, in case the other communication apparatus can not conduct communication in the channels the aforementioned channel is set, the channel is allocated as the channel used by the communication apparatus. | 07-29-2010 |
20100315676 | COMMUNICATION APPARATUS AND CONTROL METHOD OF COMMUNICATION APPARATUS - An apparatus includes a recognition unit configured to recognize a function included in a communication partner and a determination unit configured to determine processing, which the communication partner performs on transmission data, according to the recognized function and a type of the transmission data. | 12-16-2010 |
20120013513 | LOOP ANTENNA - A loop antenna includes a parasitic element arranged at a position almost concentric to a loop element and having an opening portion smaller than the half perimeter of the loop element at a position opposite to the feeding point of the loop element. | 01-19-2012 |
20140375524 | ANTENNA AND COMMUNICATION APPARATUS - The present invention provides an antenna in which first and second conductors each having a first width are spirally arranged on first and second planes, respectively, such that a conductor-to-conductor distance is equal to a second width, and an inter ends of spirals of the first and second conductors are connected with a conductor. In this antenna, the direction in which the spiral of the first conductor runs from its outer end to its inter end and the direction in which the spiral of the second conductor runs from its inter end to its outer end correspond to each other, the first width is greater than or equal to the second width, and the first and second conductors are alternately arranged in at least a portion thereof as viewed in a radius direction from an axis of the spiral. | 12-25-2014 |
20150061401 | WIRELESS POWER TRANSFER SYSTEM, WIRELESS POWER TRANSFER APPARATUS, WIRELESS POWER TRANSFER METHOD, CONTROL METHOD FOR THE WIRELESS POWER TRANSFER APPARATUS, AND STORAGE MEDIUM STORING PROGRAM - The disclosure relates to a wireless power transfer system composed of a power transmission apparatus including power transmission elements configured to transmit power and a power reception apparatus including power reception elements configured to receive the power. The wireless power transfer system communicates information related to the power transmission elements or the power reception elements between the power transmission apparatus and the power reception apparatus and selects a combination of the power transmission element and the power reception element used for wireless power transfer among plural combinations of the power transmission elements and the power reception elements by using the communicated information. | 03-05-2015 |
