Abstract: An adaptive beamforming apparatus and method of an array antenna in a communication system. First, a tentative symbol decision value is obtained by processing a traffic signal vector, and a final updated coefficient value is obtained by performing a least mean square (LMS) algorithm at least once with respect to the tentative symbol decision value and a pilot signal vector on the assumption that the tentative symbol decision value is a transmitted symbol value. Then an adaptive beam which corresponds to a final symbol decision value is formed using the traffic signal vector and the final updated coefficient value.

Abstract: A computer-based method and system for capturing and verifying a handwritten signature. The handwritten signature may relate to a document, such as an electronically stored document. An image of the document is displayed. A user signs the document electronically, and the handwritten signature is electronically captured. A set of measurements relating to the handwritten signature is determined and stored in a signature envelope. Optionally, a checksum of a checksum of the document can be determined and stored in the signature envelope. The claimed identity of the signatory can also be stored in the signature envelope. The signature envelope is encrypted. The signature envelope can be communicated to another application or computer platform, or stored for later verification. The signature envelope is decrypted, and the set of measurements stored in the signature envelope are compared against a known set of handwritten signature measurements to verify the identity of the signatory.

Thereafter, the pair of weighted bias currents presented to a node are adjusted in response to the selected pair of clock signals, where the selected pair of clock signals operates to adjust the rate of change of the weighted bias currents.

Abstract: A VDSL customer drop testing arrangement and equipment utilizes a test set top box having a sign-on identifier unique to an authorized test device to perform testing of the customer drop without the need to provision the drop for receipt of video programming or data services from any network information or service providers (VIPs or DSPs). Because the test arrangement of the present invention does not require such provisioning, isolation of the customer drop is achieved. Such isolation insures that the test set is not being affected by problems originated from a VIP or DSP.

Abstract: A web browser (54) downloads a JAVA applet (84) from a web server (52) that maintains an IP connection between a customer's browser program and a push server. A sales or service representative interacts with a terminal (58) to view web pages on the web server. When the representative desires the customer to receive a desired web page, the representative selects a “follow me” control on the terminal. The follow me control directs the push server to transmit an address of a web page to the applet. The applet in turn forwards the address to the web browser program to download a new web page. The present invention is used to transmit information to a web browser program that may be connected to other web sites.

Abstract: When telephone calls are placed by dialing a special number such as an “800” number, the dialed number is converted to a specially configured translation number that includes a destination output set of digits which are preferably the last four digits of the dialed number. This translation number is transported over the network from an originating switch to a terminating switch which then outputs the output set to the destination. Advantageously, the terminating switch also replaces the prefix portion of the translation number with an output prefix consisting of at least the NXX portion of the dialed number and outputs this prefix along with the output set to the destination for use in call tracking.

Abstract: An antenna apparatus which can increase capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective programmable phase shifter. The phase of each antenna element is programmed for optimum reception during, for example, an idle mode which receives a pilot signal. The antenna array creates a beamformer for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference. Various techniques for determining the proper phase of each antenna element are accommodated.

Abstract: A method and apparatus to inform an online computer user of the presence of an incoming telephone call without disturbing an associated modem connection is disclosed. A device is connected to a telephone line, modem and telephone set, and utilizes a call waiting service provided by the telephone company. Upon detection of a call waiting signal the device generates a four second warbling tone to a piezoelectric sounder alerting the user to the presence of an inbound telephone call. The user may answer or ignore the telephone call. Caller identifiers included in incoming calls may be used to alert the user of the origin of the incoming call before the user decides to accept or ignore the call. When the device determines that the user has lifted the telephone set, it places the modem on hold, generates a signal displayed as a colored LED display, connects the telephone to the incoming tip/ring connection, thus establishing a connection to the caller.
