Imaging apparatus and imaging method
An imaging apparatus and an imaging method supply an optimum amount of image data to another apparatus. When a PDA has a maximum transfer rate of 1.5 Mbps, a mobile phone determines that the maximum speed of communication with the PDA is low, reduces the amount of moving image data captured by a CCD of the mobile phone accordingly, and supplies the captured moving image data to the PDA. The PDA therefore displays a low-quality moving image on its display unit. When the PDA has a maximum transfer rate of 480 Mbps, the CPU of the mobile phone leaves unchanged the amount of moving picture data captured by the CCD and supplies the captured moving image data to the PDA. The PDA then displays a high-quality moving image on its display unit. The foregoing may be advantageously applied to digital cameras. |

Systems and methods for supporting IP ownership in a cluster
While each node in a cluster of nodes sources connections with the same IP if each node allocates a port on this IP independently, there may be port clashes. Also, the return traffic is not guaranteed to hit the originating node. These issues are addressed by allocating a port in such a way that the response traffic hashes back to the originating node. A good hash is chosen such that the ports are equally divided among the nodes. When a node leaves, the other nodes take over the port range used by this node. When a node joins, the node takes back its share of ports. |

Outer loop link adaptation for device resumption
Outer loop link adaptation for device resumption. A user equipment (UE) and base station (BS) may be in communication in a first network (e.g., an LTE network). Communication between the UE and the BS may be interrupted, e.g., due to a long fading environment, the UE tuning away to a second network (e.g., a CDMA network). Accordingly, the measured error rate may increase dramatically. After resumption from the interruption, a negative offset may be applied to a reported SINR value from the UE due to the previous increase in error rate. Upon improvement in the error rate, a larger, positive offset adjustment may be added to the negative offset, allowing the estimated SINR to return to reported SINR more quickly. Additionally, the error rate estimation may be adjusted to converge to a more recently measured more quickly by decreasing a feedback filter coefficient. |
