| 20100124219 | Method for Routing Packets in Ad-Hoc Networks with Partial Channel State Information - A method routs a packet from a source node, via relay nodes, to a destination node. The nodes are connected by wireless links x. A channel power gain γ is measured for each link x. Resource trade-off curves y=ƒ(x) are constructed for each link x from the channel power gains γ, wherein y represents a set of resources. A hyperbolic upper bound h/x+c is fitted to each resource curve, such that h/x+c≧ƒ(x), wherein h is a scale factor, and c is an offset. A route with an optimal resource allocation is selected according to the hyperbolic upper bounds. Then, the packet is transmitted from the source node to the destination node using the route. | 05-20-2010 |
| 20100128703 | Method for Routing Packets in Wireless Ad-Hoc Networks with Probabilistic Delay Guarantees - A method determines an optimal route to deliver a packet from a source node via relay nodes to a destination node in a network. A graph of nodes connected by edges represents possible routes in the network. A probability that the packet arrives at the destination before a deadline time is assigned to each edge. A minimal delay route is selected from the possible routes, and an arrival time for delivering the packet using the minimal delay route is determined. The arrival time is comparing to a deadline time, and the probabilities are scaled accordingly until the minimal delay route is an optimal route. | 05-27-2010 |

| 20080308361 | Method and System for Determining Instantaneous Peak Power Consumption in Elevator Banks - A method and system determine peak power consumption over time by a bank of elevator for servicing a set of passenger hall calls and delivery requests, and selecting elevator schedules that keep peak power consumption below a predetermined threshold. For each car in response to receiving a hall call, a set of all possible paths to service all hall calls assigned to the car are determined, in which each path includes a set of all possible segments. A peak power consumption for each possible segment is also determined. The peak power consumptions for the set of all possible segments for each time instant are added to determine a total peak power consumption for each time instant, and a particular path is selected as a schedule to operate the bank of elevator cars, if the total peak power consumption for any instant in time while operating according to the selected schedule is below a predetermined threshold. | 12-18-2008 |
| 20090148072 | Method and Apparatus for Touching-Up Images - A method and camera apparatus touches up a source image to produce a target image. The source image is partitioned into non-overlapping tiles of pixels. Each tile is labeled. A probability distribution of the labels is inferred, in which the probability distribution is a conditional random field. Weights are determined from the conditional random field. Then, each tile of the source image is transformed according to the weights to produce a corresponding tile of a target image. The transforming maximizes a conditional likelihood of the target image given the source image, while marginalizing over all possible labelings of the source image. | 06-11-2009 |

The possible paths from the source to the destination are represented as a stochastic graph of nodes connected by edges. Each edge has an independent probability distribution over a cost of the edge. A constraint for reaching the destination is defined. The graph is reduced to a relatively small set of deterministic minimum cost problems, which can be solved to determine an optimal path that maximizes a probability of reaching the destination within the constraint. | 07-09-2009 |

The grid graph includes one node for each pixel in the input image, and adjacent nodes in the grid graph are connected by arcs. Each arc is directed and has an associated cost. A cut is applied to the arcs of the grid graph using a cost function. A seam of pixels is determined from the cut so that coordinates of the pixels in the seam enforce monotonicity and connectivity constraints. Then, the input image is resized according to the seam to produce an output image while minimizing a change of energy in the output image when compared with the input image. | 09-01-2011 |
