Method and apparatus for a feed forward equalizer for a communication system are described wherein an equalizer may comprise a tapped filter having multiple filter multipliers, a correlator having multiple correlator multipliers, and a set of shared delay elements to connect to the filter multipliers and the correlator multipliers. Each delay element may include multiple delay stages. A first delay stage may receive an input data signal and output a first delay signal to one of the correlator mu...

A security server distributes security polices to the client computers. Each security policy includes an identifier identifying the process to which the policy pertains, and security rules for use with that process. The identifier includes a version hash and a code hash. The version hash of a process is likely to remain unchanged if the process is modified by a legitimate agent, such as by a software update. The code hash of a process is likely to change if the process is modified by a malicious...

A method and system for providing call forwarding in an IP telephone network is disclosed. First, when a telephone number for a first telephone from a second telephone is dialed, the call is routing to a call manager. Call setup procedures with a BRG responsible for the first telephone are then initiated. The BRG then checks stored call forwarding profiles to determine whether there is an active call forwarding profile for the first telephone. The call is connected to the first telephone if an a...

Feed forward amplifiers and methods particularly suited for power multichannel microwave amplifiers for cellular phone base stations and the like. The input signal is modulated with a small percentage of modulation at a relatively low frequency before being amplified by the main amplifier. At the same time, the input signal is also coupled to provide inphase and quadrature components thereof to be mixed with the amplifier output and lowpass filtered to extract a component of the low frequency re...

A new aerodynamic design for an automobile is called the Forward Tilt Windshield. By positioning the car's windshield such that the angle between the windshield and hood is less than ninety degrees, the Forward Tilt Windshield will direct downward the air encountered by the car during forward travel. The air flow will then be directed into a open-ended channel, from the base of the windshield to the bottom of the car, by contouring the windshield such that its outer edges at the sides of the car...

An apparatus for changing power direction for a bicycle is provided. The apparatus for changing power direction roughly including a shaft housing, a change ring, a carrier, a sun gear and a sprocket cap is located between a pedal shaft and a driving sprocket. The shaft housing supports the rotating pedal shaft and controls the carrier by using a plurality of pawls to be released from and inserted into a plurality of openings formed at the inside of a rim of a right cap of the shaft housing when ...

A method and system of managing call forwarding includes establishing criteria for selecting among possible links between nodes for forwarding calls from an originating node to a destination node. In the preferred embodiment, the selection of the possible links is made at a called node from which the call is to be forwarded. Based upon the administrable criteria, there is a determination as to whether an intermediate node along the call path between the originating node and the called node is to...

A feed forward amplifier (200) comprises a main signal path (201), an error signal path (203), and a third signal path (205). In the preferred embodiment of the present invention, the third signal path (205) comprises a gain and phase adjuster (245), delay circuitry (249), summing circuitry (251), and an error cancellation detector (255). The third signal path (205) is designed to match passive components in a component section (207) of the main signal path (201) to the error signal path (203). ...

A family of integrated filter forward converters includes a filter inductor is magnetically included in the transformer assembly. A basic circuit includes a DC voltage source, two cross-coupled capacitors, a clamp diode, a power switch, two identical transformers (or equivalent to a transformer and a filter inductor), two rectifying diodes, a filter capacitor and a load resistor. Several useful versions can be obtained by modifying the basic circuit for different applications. Both the input and...

A forward-drive apparatus for a bicycle comprises a drive transferring portion 40 including a pedal 20 fixed to a pedal shaft 22 of a bicycle and for transferring the drive force to a drive sprocket 30 connected by means of a chain to a rear wheel; a drive switching portion 50 for enabling the drive force generated from the drive transferring portion 40 to rotate the rear wheel in a forward or idle state; and a drive coupling portion 60 for enabling the forward or idle rotation of the drive spro...
