    摘要: A housing assembly for an ISDN multimedia capable wireless interface device having a plurality of operating capabilities. The housing assembly comprises a main housing, a cover, hinge assembly for coupling the cover to the main housing. The hinge assembly enables the cover to pivot and articulate relative to the main housing to transform the housing assembly into a plurality of mechanical configurations via sensors responsive to the pivoting and articulating of the cover provided in the housing assembly. The cover includes an illuminated keyboard having a display for selectively providing pixel-based graphics and light. The keyboard is disposed over the display when the device is operating in one of a plurality of operational modes. Each keypad of the keyboard has an image viewing surface and coherent light pipe mechanism for conducting light generated by the display to the image viewing surface the keypad. The upper rear surface of the main housing includes three unmarked softkeys which enable finger access for various device functions. The keys are software controlled and as such operate to provide a mouse, cursor control, number and text generation, video camera control and other like device features.

    摘要: An arrangement for providing synchronization between a number of overlapping area access points within a wireless LAN utilizes a Power over Ethernet (PoE) cable connection to transmit synchronization signals from a centralized hub/switch to each of the access points connected to the cable. The synchronization signal takes the form of a direct sequence spread spectrum (DS-SS) signal that is coupled onto the twisted pair used to provide the low voltage PoE signal to various powered devices. At each access point, a filter is used to remove the synchronization signal from the PoE transport, allowing for the group of access points to share a common beacon signal and allow for frequency re-use among the access points. The DS-SS signal is preferable created by a combination of a baseband signal and a set of separate pseudo noise (PN) sequences defining a precision phase (“pilot tone”) signal, a time mark (superframe/beacon) signal, and a time-of-day (real-time clock) signal.
