Abstract: The present invention includes a method and device for calculating an encryption key, K?c, for use in the initialization of an encryption algorithm. The present invention discloses a method for calculating the encryption key, K?c(x), by obtaining a ciphering key, Kc(x), determining a maximum ciphering key length, L, based on the requirements of the two devices wishing to communicate, and determining a maximum usable encryption key length, Lmax. The ciphering key, Kc(x), is then manipulated through an addition function or an exclusively-or function with a polynomial g1(x). The result is multiplied with a polynomial g2(x), which spreads the starting points of said encryption key, K?c(x). The encryption key is thus determined according to K?c(x)=g2(L)(x)[Kc(x) mod g1(L)(x)]. The method of calculating the encryption key, K?c, ensures that a maximum ciphering key length is not exceeded. In addition, the method provides new possible starting points each time a new encryption key, K?c, is generated.

Abstract: A cross-coupled dielectric resonator circuit. Resonator circuits in accordance with the invention may be used to build low-loss compact filters, oscillators, and other circuits, particularly microwave circuits. The resonators are arranged relatively to each other within an enclosure in a very efficient and compact design that enhances adjustability and coupling between adjacent resonators and the cross-coupling of alternate resonators.

Abstract: The invention comprises a technique and associated mechanisms by which dielectric resonator circuits, such as filters, can be tuned in both frequency, bandwidth or both without the need for irises, tuning screws and/or tuning plates. In accordance with the invention, the positions of the dielectric resonators are adjustable relative to each other within the cavity in multiple ways, including vertically and horizontally. The dielectric resonators also may tilt relative to each other. Furthermore, an off-center longitudinal hole can be machined in one or more of the dielectric resonators so as to make the electromagnetic field of the resonator non-uniform so that the dielectric resonator can be rotated about its longitudinal axis to alter the coupling between dielectric resonators.

In one arrangement, the control member includes one set of sensors that measure radial strain and another set of sensors that measures hoop strain. The device can also include a load sensor for measuring the load applied to the control member. In one embodiment the measurement module includes a processor that determines soil modulus based the strain measurements and the measured load.

Abstract: A system, method, and computer program product for allocating resources to a communication channel between a transmitter and a receiver are disclosed. The receiver implements a procedure that instructs the transmitter to utilize the maximum available bandwidth, consistent with maintaining satisfactory communication channel performance. When the performance of the communication channel degrades, the receiver measures the strength of a communication signal received from the transmitter. If the communication signal strength satisfies a threshold, then the bandwidth dedicated to the communication channel may be decreased, and at least one of the number of bits per symbol and coding rate may be increased. By contrast, if the communication signal strength fails to satisfy a threshold, then the transmitter may increase the transmission power and/or reduce the user rate of the communication link.

Abstract: A pixel is textured by storing a first texel reference value, a second texel reference value, and texel mapping values where each texel mapping value represents a k-tuple of (ternary) references to the first texel reference value, the second texel reference value and a third texel reference value to thereby represent a block of texels. A pixel value for the pixel is generated from the stored texel values and the pixel is displayed responsive to the generated pixel value. In some embodiments, respective pluralities of texel reference values and texel mapping values that map thereto are stored for respective ones of a plurality of overlapping blocks of texels. In further embodiments, a first mipmap value for a pixel is bilinearly interpolated from the retrieved texel values for the set of nearest neighbor texels. A second mipmap value for the pixel is generated by averaging the retrieved texel values for the set of nearest neighbor texels.

Abstract: A dam or barrier around the periphery of a die in a flip-chip package changes the shape of the underfill to reduce stress resulting from edge effects. The dam can include a treated region of a substrate having an affinity to an underfill material. The treated region causes liquid underfill material to bead, thereby controlling the wetting angle of the underfill material and shaping the underfill to eliminate sources of stress such as underfill fillet regions that are subject to significant shrinkage. The dammed underfill additionally avoids or reduces the extent of areas having thermal coefficients of expansion that differ from the optimal level because of low filler particle concentration.

Abstract: The present invention encompasses monoclonal and chimeric antibodies that bind to lipoteichoic acid of Gram positive bacteria. The antibodies also bind to whole bacteria and enhance phagocytosis and killing of the bacteria in vitro and enhance protection from lethal infection in vivo. The mouse monoclonal antibody has been humanized and the resulting chimeric antibody provides a previously unknown means to diagnose, prevent and/or treat infections caused by gram positive bacteria bearing lipoteichoic acid. This invention also encompasses a peptide mimic of the lipoteichoic acid epitope binding site defined by the monoclonal antibody. This epitope or epitope peptide mimic identifies other antibodies that may bind to the lipoteichoic acid epitope. Moreover, the epitope or epitope peptide mimic provides a valuable substrate for the generation of vaccines or other therapeutics.
