The present invention provides a tablet computer and a docking station assembly. This docking station comprises a docking assembly for positioning with three degrees of freedom and having a data connector for mechanically supporting and interfacing with the tablet computer. A support member couples the docking assembly to an expansion base. The base includes a number of ports for interfacing with a variety of peripheral devices or power supplies. These varieties of ports mount to a printed circuit board contained within the expansion base. A flexible printed circuit (FPC) combines the signal pathways for the variety of ports, allowing the signal pathways to travel from the printed circuit board and to the data connector. The tablet computing device has a plurality of contact or touch points positioned on the right and left edges of the tablet to facilitate aligning the tablet to the docking assembly in either a landscape or portrait mode.

A method and device which dynamically detects, tracks and filters interfering signals with sufficient speed (i.e. within one IS-95 CDMA data frame period, or 20ms and fidelity to eliminate or greatly reduce the deleterious effects of narrow band interferor signals on a CDMA link. When inserted in an RF signal path an Adaptive Notch Filter (ANF) detects narrow band interferors above a threshold level within the CDMA signal. Detection is accomplished by continuous scanning of a preset excision band, e.g. a specified narrow band associated with an AMPS system. Detected interferors are then automatically acquired and suppressed. This is achieved by electronically placing a rejection notch at the frequency of the interferors. Multiple notch filters may be used to simultaneously suppress multiple interferors. In the absence of interferors a bypass mode is selected allowing the RF signal to bypass the notch. Upon detection of an interferor, a switch is made to a suppression mode where the interferor is steered through a first notch section and suppressed. Alternatively, an external control line may be used to select the bypass mode so that the signal is allowed to pass the notch section, regardless of interferer content.

A Multi-User Detection device and method for DS-CDMA to allow enhanced signal reception under Multi-User Interference (MUI) at either the Remote Station or the Base Station is disclosed. The method includes the steps of relaying current channelization code use at Base Stations to Remote Stations operating in the vicinity of the Base Stations. This information is used by an MUD device at the Remote Station, to improve its ability to separate signals transmitted from different Base Stations. The downlink channelization code information is used to recreate the interference received by all neighboring Base Stations transmissions at the Remote Station. The same method can be applied at the Base Station side. The Uplink Channelization Code Usage information is relayed to each Base Station from its neighboring Base Stations. Recreating the total Remote Station interference at the Base Station allows a multistage interference cancellation based MUD to enhance its capability of receiving Remote Stations in its coverage area.

Reverse link reception and reverse link capacity are improved at a multi-sector radio base station (RBS) by forcing always-softer reverse link handoff conditions for mobile stations served by the RBS. Whenever a serving sector reverse link is assigned to a mobile station at the RBS, one or more additional reverse links are assigned to it from remaining sectors of the RBS. Such assignments are made irrespective of whether those sectors are, or could be, used to serve the mobile station on the forward link. The RBS improves its reception of the mobile station's reverse link transmissions by combining signals from all of the assigned reverse links. With improved reception, mobile stations can be commanded or configured to reduce their reverse link transmit power, thereby reducing reverse link interference and increasing reverse link capacity. Always-softer handoff may not be forced unless the mobile station has a reverse supplemental channel, since the use of such channels makes interference reduction particularly beneficial.
