Abstract: A decision feedback equalizer system is disclosed. The decision feedback equalizer system includes a current summer core that in current mode, removes inter-symbol interference from a signal, and, a CMOS latch component, that is coupled to the current summer core, that receives a current mode signal and outputs a CMOS compatible signal. The components of the decision feedback equalizer system are controlled by a single clock.

Abstract: A universal portable minidisk drive system adopts the (1) universal head (2) laser pin (3) timing/coordinate clock track to have the long-time, continue-playing for all the different disk media such as optic disk, magnetic disk or magnetopic disk. The universal head enables the universal disk to read/write all the different disk that the portable computer only needs to have one kind of disk drive. The laser pin pushes the track density to the extreme limit that the minidisk can store a large amount data. The timing/coordinate clock track introduces the (track, sector) coordinate system to the disk that the access/recover time is reduced. The disk drive can play continuously in the vibrant environment.

Abstract: A personal communications terminal (PCT) in a case having a first half hingedly connected to a second half. The PCT operates in an open and a closed position and comprises a mobile telephone unit and a personal digital assistant (PDA) unit electronically connected to the mobile telephone unit. The PDA unit is a fully functional personal computer. The PDA unit comprises a memory for application software programs, a memory for data, a processor for performing operations with the data and the application programs, a modem for passing data between the PDA unit and the mobile telephone unit, and a mobile data interface for passing data between the PDA unit and the mobile telephone unit without utilizing the modem. When the PCT is in the open position, it forms two interior faces which include a PDA display screen on one face and a full alpha-numeric keyboard on the other face.
