20110007720 | WIRELESS COMMUNICATION METHOD, BASE STATION APPARATUS AND WIRELESS COMMUNICATION SYSTEM - A base station apparatus includes a base-station receiver which receives information indicating the occurrence of the given event in the wireless terminal device, the information being transmitted from the wireless terminal device using the common slot. The base station apparatus includes a base-station transmission and reception manager which determines the number of random slots assigned as random slots to transmit the bandwidth request information for the given event among random slots in the random access period, based on the occurrence of the given event received by the base-station receiver. The base station apparatus includes a base-station transmitter which transmits, in the base station apparatus, information on the assigned random slots to the wireless terminal device of random access period. | 01-13-2011 |
20110013578 | WIRELESS COMMUNICATION METHOD, WIRELESS COMMUNICATION SYSTEM, BASE STATION, AND TERMINAL STATION - A base station performs bandwidth assignment for each terminal station or each wireless link even when the base station does not receive a bandwidth request in random access from the terminal station in the demand assignment period present in a specific period in which a transmission frequency of data to transmit is high, the specific period being specified for each terminal station or each wireless link between the terminal station and the base station, and the terminal station transmits at least one of bandwidth request information and the data to transmit in a bandwidth assigned by the base station. | 01-20-2011 |
20110038317 | WIRELESS TERMINAL CALL METHOD AND WIRELESS ACCESS SYSTEM - A wireless terminal receives a first broadcast signal transmitted from a wireless base station; detects whether a part of a wireless terminal ID of the own wireless terminal is included in the first broadcast signal received in the broadcast signal reception or not and determines that the second broadcast signal is to be continuously received when the part of the wireless terminal ID is included; and receives the second broadcast signal when it is determined in the broadcast signal determination that the second broadcast signal is to be received, stops receiving data transmitted from the wireless base station when assignment information to be transmitted to the own wireless terminal is not present in the received second broadcast signal, and receives data transmitted from the wireless base station to the own wireless terminal based on the information on the assignment position of the wireless slot included in the second broadcast signal when the assignment information to be transmitted to the own wireless terminal is present in the received second broadcast signal. | 02-17-2011 |

20090141135 | LENS DRIVE DEVICE, IMAGE PICKUP DEVICE AND LENS DRIVE METHOD - A lens drive device in at least one lens barrel holding a lens moveably includes a motor to drive the lens; an acceleration detection section to detect an acceleration; and an output control section to control an output of the motor corresponding to the acceleration detected by the acceleration detection section. The output control section determines whether the acceleration detected by the acceleration detection section falls within a predetermined acceleration range or not. When the acceleration is determined to be within the range, a further determination of whether the lens drive device is in a stationary state is performed. When it is determined not being in the stationary state, the motor is driven by a maximum drive voltage. When it is determined being in the stationary state, a further determination of whether the posture is horizontal or not is performed. | 06-04-2009 |
20100046097 | LENS BARREL, LENS DRIVING APPARATUS, CAMERA, AND MOBILE INFORMATION TERMINAL - At least one objective of the present invention is to provide a lens barrel capable of detecting a position of a retractable lens retaining frame with high accuracy, a lens driving apparatus, a camera, and a mobile information terminal using the lens barrel. | 02-25-2010 |
20110033178 | LENS BARREL, CAMERA AND PORTABLE INFORMATION TERMINAL APPARATUS - A lens barrel includes a telescopic cylinder, at least one movable lens, and a retractable lens. The telescopic cylinder includes at least one movable cylinder that can be accommodated in a fixed cylinder. The movable lens is retained in the movable cylinder. An optical axis of the movable lens determines a reference axis of the lens barrel. The retractable lens can be retracted in a plane perpendicular to the reference axis from a photographing position on the reference axis to a retracted position off the reference axis. In a photographing state, the retractable lens is adjacent to the movable lens, and the movable lens and the retractable lens are coaxially aligned along the reference axis. The retractable lens moves to the reference axis from the retracted position immediately after the movable cylinder of the movable lens reaches a maximum protruded position. | 02-10-2011 |
20110141586 | LENS BARREL, LENS DRIVING APPARATUS, CAMERA, AND MOBILE INFORMATION TERMINAL - A lens barrel includes a plurality of lens groups each having at least one lens; a plurality of lens retaining frames which retain a corresponding one of the plurality of lens groups; a telescopic cylinder containing therein the plurality of lens groups and the plurality of lens retaining frames; a lens retaining frame driving device configured to drive at least one of the lens retaining frames; a moving member which moves in a direction along the photographing optical axis; and a position detector configured to detect a change in a position of the moving member, wherein the plurality of lens retaining frames including a retractable lens retaining frame configured to retract the at least another one of the plurality of lens groups from the photographing optical axis to a retracted position out of the telescopic cylinder in the collapsed state. | 06-16-2011 |
20110273781 | LENS BARREL, CAMERA AND MOBILE INFORMATION TERMINAL - A lens barrel including a telescopic cylinder configured to be accommodated within a fixed frame; a plurality of lens groups configured to be retained in the telescopic cylinder; a lens driving device configured to drive the plurality of lens groups along a longitudinal axis of the telescopic cylinder between a collapsed position in which at least one portion of the plurality of lens groups is stored in the fixed frame and an extended position in which the at least one portion of the plurality of lens groups is extended out of the fixed frame; and a retractable lens group configured to be retracted into the fixed frame through an opening in a wall of the fixed frame when the telescopic cylinder is in the extended position. | 11-10-2011 |
