  • Publication number: 20160331209
    Abstract: Exemplary apparatus and method can be provided. For example, using at least one light source first arrangement, it is possible to provide pulses of light to at least one portion of a biological structure. At least one detector second arrangement can be used to detect images from the portion(s) based on the pulses, and provide data based on the detection. With at least one configuration, it is possible prevent and/or reduce a movement of the apparatus within at least one anatomical body (i) is a particular surface of the apparatus, (ii) covers at least one portion of the surface, and/or (iii) extends from the surface. In addition or alternatively, with at least one computer third arrangement, it is possible to receive the data, and control a timing of at least one of activation or deactivation of at least one portion of the first arrangement based on the data.

  • Publication number: 20150253240
    Abstract: Exemplary apparatus and method can be provided for obtaining data regarding a plurality of samples. For example, using at least one arrangement, it is possible to receive interferometric information that is based on radiations provided from a reference and the samples that are provided in respective chambers. Alternatively and/or in addition, based on the interferometric information, it is possible to discriminate between agents to identify a particular agent that affects a particular function within at least one of the samples.

  • Patent number: 9091862
    Abstract: A partitioned aperture wavefront imaging system includes an imaging system comprising a partitioned aperture lens array positioned at the aperture plane or Fourier plane between the entrance plane and camera plane of an imaging system. The partitioned aperture lens array can include 2 or more off-axis lenses symmetrically distributed about an optical axis, and adapted to produce simultaneously at the camera plane at least two images of an object, or intermediate image of an object, presented at the entrance plane. Preferably, the partitioned aperture lens array includes from 3 to 5 off-axis lenses and produces 3 to 5 images at the camera plane from which phase and amplitude information about the light field can be determined. The partitioned aperture wavefront imaging system provides enough information about the light field presented at the entrance plane to enable reconstruction of the light field at other planes relative to the entrance plane.

  • Patent number: 8996680
    Abstract: A non-transitory computer readable media having instructions stored thereon that, when executed by a processor, cause the processor to optimize a network that is formed from a plurality of nodes. The instructions cause the processor to execute an order that the plurality of nodes perform a probing operation. The order is typically round robin. The processor receives a request from a client that identifies a next node to perform the probing operation. Based on the request, the processor changes the order so that the next node performs the probing operation after the current node that is performing the probing operation has completed the operation.

  • Publication number: 20150087902
    Abstract: A method of creating a phase contrast image is provided. In some embodiments the method comprises illuminating the target region of a sample with a first light source to provide a first oblique back illumination of the target region of the sample, and detecting a first phase contrast image from light originating from the first light source and back illuminating the target region of the sample. In some embodiments the method further comprises illuminating the sample with a second light source to provide a second oblique back illumination of the target region of the sample, and detecting a second phase contrast image from light originating from the second light source and back illuminating the target region of the sample. In some embodiments a difference image of the target region of the sample is created by subtracting the second phase contrast image of the target region of the sample from the first phase contrast image of the target region of the sample.

  • Patent number: 8849969
    Abstract: A method is disclosed for optimizing a network that is formed from a plurality of nodes. The NC node of the network compiles an order that the plurality of nodes perform a probing operation. The order is typically round robin. The NC node receives a request from a client that identifies a next node to perform the probing operation. Based on the request, the NC node changes the order so that the next node performs the probing operation after the current node that is performing the probing operation has completed the operation.

  • Publication number: 20110205935
    Abstract: A node forms a network by scanning for an existing network. If an existing network is not found, the node operates as a network controller node of the first network and admits at least one client node to the first network. As a network controller node, the node designates one of the client nodes as a scout node. The scout node removes itself from the first network and scans for a second network. If the scout node does not return to the first network after a predetermined time, it is assumed that the scout node has found a second network. The network controller node of the first network then designates the remaining client nodes as scout nodes, and then joins the second network as a client node. Therefore, multiple networks are avoided.
