During a data transfer operation of bit of information, the voltage level on the conductor is changed from a first voltage level to a second voltage level and maintained at the ... 08/18/05 - 20050180514 - Data transmission apparatus using asynchronous dual-rail bus and method therefor The present invention relates to a data transmission apparatus using an asynchronous dual-rail bus and a method therefor which can reduce power consumption for transferring data by limiting the number of dual-rail buses transferring data when a transmission side transfers an identical data. ... 07/14/05 - 20050152460 - Transmitting/receiving system, receiver and transmitter with crosstalk suppressing function From a transmitter to a transmission line, a baseband signal is transmitted together with a replica signal created by superposing the baseband signal onto Carrier Frequency C1. Similarly, from a transmitter to a transmission line, a baseband signal is transmitted together with a replica signal created by superposing the baseband ... 06/23/05 - 20050135490 - Methods of providing communications services Methods, systems, and products are disclosed for providing communications services. One method transmits signals to a destination via a first physical media. Signals are also transmitted to the destination via a second physical media. This second physical media is dynamically shared amongst multiple destinations to provide additional bandwidth when required. ... 06/23/05 - 20050135489 - Noise-tolerant signaling schemes supporting simplified timing and data recovery Described are communication systems that convey differential and common-mode signals over the same differential channel. Noise-tolerant communication schemes use low-amplitude common-mode signals that are easily rejected by differential receivers, thus allowing for very high differential data rates. Some embodiments employ the common-mode signals to transmit backchannel signals for adjusting the ... ### FreshPatents.com Support |
