Title: Digital compression and storage device
Inventor: MIZUMOTO TETSUO
IPC: G11B5/02
Filed: 2009-04-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a digital compression and storage device capable of materializing an end-around carry of the binary system where digits are carried by 0, 1 in, for example, a digital/analog converter or an analog/digital converter.  <P>SOLUTION: Various digital compressions have been tried by using expression of conventional digital codes 0 and 1 and simultaneously a magnetic or magnetic field analog element. However, such compression has been found impossible in a binary system expressed by 0 and 1 in a 4-dimensional world. In the case of units of digital codes called analog minimum unit bytes of a digital binary number of 0, 1, 2, 3, 4, 5, 6, 7 and 8, they are materialized by using a magnetic or magnetic field tape while they are in analog elements. By forming a magnetic head magnetic core into a wide sharp knife edge shape or a minus driver shape from a conventional coil, a magnetic tape storage surface becomes linear. When travelling on the magnetic or magnetic field surface by the magnetic core, due to the linear magnetic tape storage surface different from the conventional surface, a cancel relative speed is increased, and data is written/read with stabler outputs of a voltage and power.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To improve the efficiency of a packet data transmission system.  <P>SOLUTION: A radio communication system has a communication channel for the transmission of data packets from a primary station 100 to a secondary station 110. In response to receipt of a data packet, the secondary station transmits an acknowledgement signal to the primary station indicating the status of the received data packet. The signal is selected from a set of at least two available signal types (for example positive and negative acknowledgements, ACK and NACK), and the power at which it is transmitted depends on the type of the signal. In one embodiment NACKs are transmitted at a higher power than ACKs, thereby reducing the chance of the primary station misinterpreting a NACK as an ACK. In another embodiment a REVERT signal is used to request retransmission of a previous packet. The REVERT signal may be identical to the NACK signal but transmitted at a higher power.  <P>COPYRIGHT: (C)2009,JPO&INPIT
