20090216888 | DATA TRANSMISSION DEVICE - A data transmission device to transmit a data file to an external device is provided. The data transmission device includes a data file storing unit to store a data file to be transmitted, a communication session establishing unit, which is capable of establishing a plurality of communication sessions between the data transmission device and the external device, a data transmitting unit to transmit data included in the data file and divided in portions concurrently through the plurality of communication sessions to the external device. | 08-27-2009 |
20100188685 | Communication Device - A communication device may be provided with a main control unit, a condition storage unit, and a sub control unit. The sub control unit may judge, in a case where data is received while the main control unit is being in the sleeping state, whether the sleeping state is to be maintained by referring to a condition stored in the condition storage unit. The sub control unit may release the sleeping state in a case where a negative judgment is made. When object data is received, at least one of the main and sub control units may register a new condition in the condition storage unit. The registration of the new condition is executed in a case where the sleeping state of the main control unit would be released although the sleeping state of the main control unit should not be released under a presumption of the object data being received while the main control unit is being in the sleeping state. | 07-29-2010 |
20100250987 | Processing Device - A processing device may comprise a first controlling unit, a second controlling unit, a first memory and a second memory. The second memory may be set to a normal operation mode in a case where the first controlling unit is in the non-sleeping state, and may be set to a low power consumption mode in a case where the first controlling unit is in the sleeping state. In the case where the first controlling unit is in the sleeping state, the second controlling unit may be configured to perform one of the below processes depending on its condition. If the second controlling unit is to perform a specific process by using a first program, the second controlling unit may perform the specific process on behalf of the first controlling unit by using the first program stored in the first memory while the first controlling unit is maintained in the sleeping state and the second memory is maintained in the low power consumption mode. If the second controlling unit is to perform the specific process by using a second program, the second controlling unit may change a mode of the second memory from the low power consumption mode to the normal operation mode, and perform the specific process on behalf of the first controlling unit by using the second program stored in the second memory, while the first controlling unit is maintained in the sleeping state. | 09-30-2010 |
20110235535 | COMMUNICATION APPARATUS - A communication apparatus including: a processing unit configured to transition between a first state and a second state and configured to perform a response process on a packet received via the network, wherein the processing unit includes: a determination unit configured to perform a first determination process; a verification unit configured to perform a first verification process for verifying the validity of the first packet, if it is determined as a first case; and a first responding unit configured to perform the response process on the first packet, if the first packet is verified as valid, wherein if it is determined as a second case that the first packet is not the packet of which the response process is to be performed by the processing unit, the verification unit dose not perform the first verification process and the first responding unit does not perform the response process. | 09-29-2011 |
