Abstract: A method for simulating behavior of first and second interrelated components within a system. The method comprises modelling behavior of said first and second components using first and second functional specifications; simulating behavior of said first and second components in predetermined circumstances by instantiating at least one first entity within a hierarchy of interrelated entities; and instantiating at least one further entity in response to the or each instantiated first entity. The or each further entity is selected by a simulation system on the basis of its hierarchical relationship with the at least one first entity.

Abstract: There is provided a sound module for a toy, the sound module including: a controller; a speaker operatively connected to the controller; and a light operatively connected to the controller. The sound module is operable in at least a first mode and a second mode. In the first mode the controller controls the speaker to provide entertaining noises. In the second mode the controller: controls the light to provide calming illumination and/or controls the speaker to provide calming noises for a first period; and then controls the light to provide invigorating illumination and/or controls the speaker to provide invigorating noises for a second period. There is also provided a toy including the sound module.

Abstract: Methods and systems for determining a location of a probe in a network are disclosed. Several methods analyze network data received by a probe to identify at least two devices in the network between which the network data is transferred. The method further includes assigning a level of certainty as to the location of the probe based on the at least two devices of the network identified. Another method for gathering information describing a location of a probe includes receiving network data from a probe, the network data representing data transmitted in the SAN through a link coupled to the probe. The link in the SAN from which the information is received defines a location of the probe. The method further includes analyzing at least a portion of a header within the network data to gather information describing the location of the probe. The location of the probe can be included in a topology of the network and the topology can be displayed along with a visual representation of the location of the probe.

Abstract: A fastener is provided comprising a shank having a head at one end and a tapered tip at the other end, and a threaded section having a helical thread on the shank. The fastener also comprises, on the head, side surfaces for engagement with a driving tool, and wherein each of the side surfaces has at least one rib formed thereon. Also provided is a method for driving a fastener, comprising providing a shank having a head at one end, a tip at the other end, and wherein the head comprises side surfaces for engagement with a driving tool, and wherein each of the side surfaces has at least one rib formed thereon. The method further comprises providing a driving tool having driving surfaces, and driving the fastener with the driving tool by engaging the driving surfaces of the driving tool with the at least one rib of the side surfaces of the head.

Abstract: A phased array antenna (400) comprises a first array element (402) and second array element (404) and a dielectric separator (408). Each of the first and second array elements (402,404) is a detection element and or an emitter element. The dielectric separator (408) is located between the first and second array elements (402, 404) and within a path of an inter-element mutual coupling (IMC) signal between the first array element (402) and the second array element (404).

Abstract: A complex switched-current bilinear integrator (100) is formed as a pair of cross coupled real bilinear integrators and has inputs (10, 11, 12, 13) and outputs (14, 15, 16, 17) for differential pairs of in-phase (1) and quadrature-phase (Q) signals and an arrangement of sample-and-hold circuits (20, 30, 40, 50) and coupled scaling circuits (70, 71, 80, 81). Dynamic element matching is used to reduce the effect of mismatch between scaling circuits by interchanging scaling circuits in different signal paths. In order to prevent cross-talk of signals between different signal paths, the change of a scaling circuit coupled to a sample-and-hold circuit is constrained to occur only at the beginning of a sampling operation by that sample-and-hold circuit.

Abstract: A fastener is described having a head formed with a recess which accommodates a square head driver, symmetrical drivers, such as PHILLIPS™ style drivers, asymmetrical style cross head drivers, such as POZIDRIV® style drivers, and combination square and cross drivers without compromising performance of the drivers.

Abstract: An ultrasonic imaging array has two independent, interleaved linear subarrays occupying a common array face. The subarrays are independently steerable and focusable in different imaging planes. The subelements making up the elements in of the subarrays is preferably quadrilateral. Adjacent subelements in each element are electrically connected via an interconnect portion such that the interconnect portion connecting each pair of adjacent subelements in each element is substantially linear and is aligned with the diagonals of the adjacent subelements. A preferred acoustic lens is curved in both azimuth and elevation directions, whereby the subarrays are independently focusable. By transmitting in one plane and simultaneously receiving in a different, orthogonal plane, a system including the array can image a 3-D region of interest (ROI). In a volumetric embodiment of the invention two orthogonal B-mode images of a structure within the ROI are displayed simultaneously.

Abstract: Non-invasive angiography is provided through use of monochromatized synchrotron radiation in a dichromographic procedure. A small quantity of an iodinated compound is introduced into the blood stream of a patient. An X-ray picture of a blood vessel such as the coronary artery can be produced by directing synchrotron radiation from a storage ring source at first and second selected wavelengths or energy levels through the blood vessel, detecting the attenuated radiation to obtain first and second signals representative of the attenuated radiation, and logarithmically subtracting the two signals to essentially eliminate all background contrast. Due to the K-absorption edge of iodine the resulting signal will emphasize the blood vessel containing the iodine.
