Abstract: A system and method for intelligently detecting a duplicate address attack is described. The system and method comprise transferring a first address conflict check message; receiving a first address conflict check response message; performing intelligent Duplicate Address Detection (DAD) to determine if the duplicate address attack is valid; and if the duplicate address attack is valid, then reporting the duplicate address attack to a monitoring server. An intelligent switch that detects the DAD attack blocks further address conflict check response messages from the attacker's MAC address.

Abstract: Embodiments of the present invention relate to systems and methods for an electronic hook switch for customer premises equipment. In an embodiment, a system includes a first lead configured to be coupled to a tip wire and a second lead and the second lead to a ring wire. A diode bridge is coupled to the first lead and the second lead had a positive output. A low side switch is coupled to the positive output of the diode bridge without a high side switch between the low side switch and the positive output of the diode bridge.

Abstract: A flexible display for displaying images comprises a plurality of columns of pixel elements, each pixel element having display elements, a pixel driver for processing an output signal from a preceding adjacent pixel element in the same column and generating and transmitting an output signal to a succeeding adjacent pixel element in the same column; electrical conductors extending between pixel elements of each column for electrically connecting the pixel driver of the preceding adjacent pixel element to the pixel driver of the succeeding adjacent pixel element; an image signal processor for generating and delivering pixel element actuating signals to a first pixel element of each the column; and support connectors extending between adjacent pixel elements in the same column and between adjacent pixel elements of adjacent columns and permitting relative movement of the adjacent pixel elements.

Abstract: DNA isolates coding for a vascular endothelial cell growth factor may be used to produce the protein via recombinant expression systems. Such protein is useful therapeutically to treat conditions in which a selective action on the vascular endothelial cells, in the absence of excessive connective tissue proliferation, is desirable.

Abstract: A system and method for invoking one or more features of a wireless device when a signal strength of a channel approaches or drops below an RSSI threshold of the channel is disclosed. An embodiment of the invention includes the steps of (1) obtaining the RSSI threshold for the channel; (2) monitoring the signal strength during an operation mode of the wireless device; and (3) invoking the feature when the signal strength approaches a predetermined limit of the RSSI threshold. In an implementation on a cordless telephone, the feature can include playing a warning, switching to a different channel, or returning a telephone line to an idle state.

Abstract: An inverted F antenna with integrated shield is constructed from an electrically conducting sheet that is folded into a shape that provides both a shield can covers an RF module of circuit and an inverted F antenna such that shield can functions also as a ground plane for the antenna. In a pre-folded state the sheet has a shield can portion and a radiating element portion that are connected to each other by a ground feed line that bridges the shield can portion and radiating element portion. The shield can portion preferably includes a plurality of walls that are foldable along respective folds. The radiating element portion preferably includes a plurality of edges and a signal feed line extending from a first one of the plurality of edges. The ground feed line extends from a second one of said plurality of edges.

Abstract: A tone detector includes at least one circuit (hereinafter “single phase reference matcher”) that not only performs a convolution of an input signal with a reference signal, but also compares the result of convolution with a threshold to determine if there is a match, and if so drives a signal active indicating that tone is present. If there is no match, another circuit (hereinafter “phase shifter”) delays the reference signal by a fraction (e.g. ⅛) of the measuring period, thereby to introduce a phase shift (e.g. &pgr;/8) between the input signal and the reference signal. The “single phase reference matcher” again performs the just-described operation, this time with a delayed reference signal, and repeats the operation as often as necessary (e.g. eight times) to cycle through the entire measuring period, thereby to ensure that tone (if present in the input signal) is detected irrespective of phase, during one of the operations.
