摘要： A system and method for reducing switching overhead in a communication network and a web-based server incorporating the system or the method. In one embodiment, the system includes: (1) an optimization engine configured to receive input data describing trunks, switches and traffic demands in at least a portion of the communication network and arrange connections between the trunks and switches such that the traffic demands are satisfied and such that a switch load or cost is reduced and (2) a report generator associated with the optimization engine and configured to produce a report containing a modified configuration having the reduced switch load or cost.

摘要： Techniques and systems for design of optical switch arrays so as to minimize power requirements are described. A design system includes a computer system hosting a design program. The design program receives parameters for the switch array, including a number N of outputs required, and either a maximum number L of stages allowed or maximum and average power requirements allowed. If power requirements are used as parameters, the design program uses N and the power requirements to compute the value of L. The design program then constructs a minimum power sequence of L switches or N switches, whichever is less. If N is less than L+1, N outputs are present and the array is complete. If N is greater than L+1, the design program then adds switches one at a time to the minimum power switch path of the array, until the array provides N outputs.

摘要： Apparatus for storing an optical image of an object comprises an imaging device having a multiplicity of pixels, each pixel including a light sensor and a multiplicity of storage cells coupled to the sensor. A lens system focuses light from the object onto the imaging device. Within each pixel a first one of its storage cells is configured to store data corresponding to a first exposure of its sensor to light from the object, and a second one of its storage cells is configured to store data corresponding to a second exposure of its sensor to light from the object. In a preferred embodiment, the pixels are arranged in an array extending along a first direction, and during the time interval between the first and second exposures, a translator is configured to produce, in a second direction, a relative translation or shift between the imaging device and the focal point of the lens system. In one embodiment, the second direction is traverse to the first direction. In a preferred embodiment, each pixel comprises a photosensitive region, and the pixels are shifted by a distance that is approximately equal to one half the pitch of the photosensitive regions as measured in the second direction. In this fashion, the invention increases the spatial resolution by increasing the effective number of pixels of the sensor without increasing the actual number of pixels. In alternative embodiment of the invention, the dynamic range of the sensor is enhanced.

摘要： A method and apparatus for grooming traffic demands according to mileage based tariffs. An Integer Linear Program (ILP) that captures the traffic grooming problem is defined, and such a linear program can in principle be solved by conventional linear program application systems which are fully familiar to those of ordinary skill in the art. However, the time required to solve such an ILP is fairly large, even for the moderately sized networks we are interested in. That is, there are many possible routes to consider, and hence many integer variables in the ILP. Therefore, further in accordance with the principles of the present invention, the ILP is advantageously run on the Delaunay Triangulation of the network rather than on the completely connected network graph.

摘要： An electro-mechanical actuator includes a comb drive and a deformable connector. The comb drive has a first capacitor plate and a second capacitor plate. The capacitor plates have teeth capable of inter-digitating. The deformable connector is configured to apply a mechanical restoring force to the first capacitor plate. The deformable connector is configured to restore the first capacitor plate to be at an equilibrium rest position in response to no control voltage being applied across the capacitor. The comb drive is more engaged at the equilibrium rest position than at a mechanical stability threshold of the comb drive. The capacitor plates are disengaged at the equilibrium rest position.
