Provided are apparatuses and methods for transmitting or receiving data packets in a data block in a communication network with a transport protocol. In one example, a loss tolerant TCP protocol is used in which a maximum segment size (MSS) may be adapted to a minimum granularity of a congestion window. Also, proactive forward error correction (FEC) packets may be added to a window of the data block. The number of proactive FEC packets may be determined, for example, based on an estimate erasure rate. In addition, reactive FEC packets may be added to the data block. Also, a receiver may receive data packets in a data block and process a selective acknowledgment (SACK) responsive to the data packets received.

A method and an apparatus for generating superpixels for a sequence of frames are described. A feature space of the sequence of frames is separated into a color subspace and a spatial subspace. A clustering is then performed in the spatial subspace on a frame basis. In the color subspace a clustering is performed on stacked frames.

An information processing apparatus includes: a display control section for displaying a window showing a first icon and a second icon of a predetermined display size on a display screen. The display control section reduces the display size of at least either the first icon or the second icon so as not to overlap with each other if it determines that the icons overlap with each other when it alters a display area of the window being displayed on the display screen.

Before packets enter a router, a packing limiting unit abandons out-of-order packets, decreases a window size, and stores temperately part of said out-of-order packets for having packets pass the packet limiting unit with a better efficiency and a precise order. After packets enter said router, a packet retransmission processing unit acquires a characteristic values and messages calculated from each characteristic value of a packet for obtaining the order, size, header, and check bits for assisting in identifying packets, and stores the characteristic values with a link list for saving memory utility. With both the abovementioned methods, problems of out-or-order and retransmission during packets are transmitted, and of an over-used amount of memory, are solved.

The invention relates to a combined minimally invasive cutting biopsy device for a bone tumour. The combined minimally invasive cutting biopsy device is structurally characterized in that a hollow annular drill is arranged in an external sleeve; the wall of the hollow annular drill is hollow and is provided with a spiral blade; the spiral blade is connected with a spiral blade knob by virtue of aconnecting rod; a trephine rotary handle is connected with the hollow annular drill; an electric drill joint is connected with the hollow annular drill; an inner core ejection rod is arranged in the hollow annular drill; and a Kirschner wire is arranged in the inner core ejection rod. According to the combined minimally invasive cutting biopsy device for the bone tumour, the defects that bone tissues and surrounding soft tissues are seriously damaged because biopsy after cutting causes serious pollution, irregular opened window and large area, and pathological fracture risk is increased can be solved. According to the invention, the cut sizes of cut biopsy skin and soft tissues are reduced, so that the pathological fracture risk in the future is lowered; and meanwhile, the pollution on the surrounding tissues by the tumour tissues and cells is reduced so as to prevent tumour cells from being transferred and diffused, thereby reducing patient pain, bringing convenience for operating, and lowering the risk of secondary pathological biopsy.

When retransmission requests are issued based on the results of error-correction decoding of received data packets to perform data transmission, statistical information indicating whether received data packets have been successfully decoded or have not been decoded is acquired, and based on the rate at which correct decoding has been made or the rate at which correct decoding has not been made, which is obtained from the statistical information, a request is transmitted to the transmission source to change the window size, which is the number of data units handled in a predetermined layer, so that when for example the communication environment is not excellent, processing can be performed at a small window size, and the occurrence of circumstances in which data retransmission and the discarding of received data are repeated can be efficiently prevented. Accordingly, data transmission efficiency in a wireless transmission system performing high-speed data transmission is improved under conditions of a poor radio wave environment.

A method for reconfiguring size of a receiving window in a communications system avoiding duplicate packet delivery to an upper layer to keep ciphering parameters in synchronization when the communications system reconfigures a receiving window of a receiver includes receiving a command for reconfiguring a size of the receiving window, reconfiguring the size of the receiving window according to the command, removing packets with sequence numbers outside the receiving window from buffers of the receiver and delivering the packets to the upper layer, determining whether a sequence number of a next expected packet is below the receiving window, and keeping the sequence number of the next expected packet and the packets in a reordering buffer of the receiver unchanged when the sequence number of the next expected packet is not below the receiving window.

A wireless mobile terminal determining a size of an advertised window depending on a current data rate of a wireless downlink transmission is provided. The wireless mobile terminal receives from a transmission control protocol (TCP) sender a data packet comprising a header portion and a payload portion; and determines the current data rate of the wireless downlink transmission to the wireless mobile terminal from signaling information contained in the header portion of the data packet; and determines the size of the advertised window depending on the current data rate of the wireless downlink transmission.
