A power adapter for powering a remote device for use with a portable computer. The power adapter has a first plug for connecting to a data port of the portable computer and for sourcing power from the data port. Also provided is a power converter electrically connected to the first plug for regulating the sourced power from the data port and outputting a power requirement to the remote device. Lastly, a second plug electrically connected to the power converter for connection to the remote device and delivery of the outputted power requirement thereto is provided. Also provided is a portable computer system which utilizes the power adapter of the present invention. The portable computer system comprises a portable computer having a data port, a remote device for use with the portable computer, and the power adapter of the present invention for powering the remote device through the data port. In a preferred embodiment of the power adapter, the remote device is a cordless telephone transceiver and the power is sourced from a mouse port of the portable computer.

A flexible cable assembly for coupling an electronic apparatus, having a port for receiving personal computer cards in accordance with the PCMCIA standard, to at least one peripheral device, said flex cable assembly comprises a personal computer card connector, in accordance with the PCMCIA standard, for connecting into a corresponding port in the electronic apparatus, and a flexible cable connected to the personal computer card connector. The personal computer card connector also comprises an interface to said at least one peripheral device. In accordance with a further aspect of the invention, the flex cable assembly can also couple a first electronic apparatus, to a second electronic apparatus, each having a port for receiving personal computer cards in accordance with the PCMCIA standard. This flex cable assembly comprises (1) a first PCMCIA card connector for connecting into a corresponding port in either the first or second electronic apparatus; (2) a second PCMCIA card connector for connecting into a corresponding port in either the first or second electronic apparatus; and (3) a flex cable coupled between the first and second personal computer card connectors.

This invention relates to the adaptation of personal computers to communication through external networks, and more particularly to the ready adaptation of such computers to networks of varying characteristics, such as telecommunications networks located in various countries of the world. The adapter has first and second controllable digital/analog convertors for exchanging signals with a digital signal processor of the computer and controllable by a bus interface controller of the computer for converting signals between digital and analog forms. The adapter also has first and second connectors of the type required by the particular external network, coupled to the convertors for exchanging signals with the external network and for exchanging signals with an external device such as a telephone set.

Personal computer system combined with an adapter for networks having

A personal computer system includes a digital signal processor (DSP) subsystem that is connectable to a plurality of application specific hardware devices. A single DSP is operable under a DSP real-time operating system (RTOS) to concurrently handle a plurality of different signal processing functions on a real-time basis. A DSP data store is connected to the DSP and to the personal computer and includes addressable locations that emulate addressable I/O registers associated with the application specific hardware devices to enable the personal computer to run a plurality of application programs controlling operation of the hardware devices. Performance is enhanced for I/O read and write operations by delaying halting of the DSP allowing such operations to complete in a cycle during which the DSP is not accessing the data store.
