Scalable, parallel processing of messages while enforcing custom sequencing criteria
Scalable, parallel (i.e., concurrent) processing of messages is provided from a message queue, while at the same time enforcing sequencing within a stream. Dependencies among messages can therefore be respected.

A system and method for optical lymph node mapping. The system is useful for guiding sentinel lymph node biopsy surgeries. A contrast agent that includes a fluorescent dye is injected near the site of a malignancy. The contrast agent drains into the lymphatic system, collecting in a sentinel node or nodes. The system utilizes one or more low-power continuous-wave lasers or light-emitting diodes modulated with a digital code sequence to probe the tissue suspected of containing the sentinel node. When the light is incident near the sentinel node, it will excite fluorescence from the dye. A portion of the scattered fluorescent light is captured with one or more photo-detectors. A correlation of the photo-detector signal and the digital code sequence is calculated to produce an estimate of the distribution of flight times for photons traveling from a given source to a given detector. The flight time distributions are used along with the measured amplitudes to reconstruct a map of contrast agent location within the tissue. |

Device and method for the optimal estimation of distortion of a transmission medium, comprising the sequential emission of pairs of quadrature complementary sequences
The present invention relates to a device and method for optimal estimation of the distortion caused by the transmission medium by means of the sequential emission of pairs of quadrature complementary sequences, estimating the frequency spectrum of a transmission channel allows obtaining information of considerable interest to analyze its characteristics or correcting the distortion effects introduced in a communication system. This invention describes a new method for extracting said characteristics generating a transmission preamble using complementary sequences, which allows upon reception identifying the distortion caused in each of the I/Q phases of a quadrature modulation system on the transmitted symbols, canceling the phase distortion effects caused by the medium and reducing the equalization of the channel to a single equalizing baseband filter identical for both I2/Q2 phases. Since the distorted frequencies are received in the receiver, they also allow extracting the temporal and/or frequency characteristics of the distortion caused by the medium they traverse with a precision depending on the length of the sequences used in coding. |

The second lens group includes a cemented doublet SU21; an aperture diaphragm; a lens SU22; and a biconvex lens L25 arranged in the above-mentioned order from the object side, and largest ones of air spaces on the axis being front and rear spaces of the aperture diaphragm except the back focal length. The wide angle optical system is divided into the first lens group and the second lens group at the second largest air space operating as a boundary. |

Optical lens assembly for capturing images and image capture device therewith
The invention is an optical lens assembly for capturing images and an image capture device therewith. The optical lens assembly for capturing images includes, along an optical axis, a total reflection prism, a first lens group having negative focal power, wherein the first lens group comprises a lens having negative focal power, a second lens group having positive focal power, wherein the second lens group comprises at least one lens having an aspherical optical surface, a third lens group having positive focal power, wherein the third lens group comprises at least one lens having positive focal power and at least one lens having negative focal power, and a fourth lens group having positive focal power, wherein the fourth lens group comprises at least one lens having an aspherical optical surface. Thereby, the aberration can be improved and a thin lens module for capturing images can be achieved. |

Lens barrel
A lens barrel capable of distributing, upon receipt of the impact of, e.g., dropping, a torque load so as not to concentrate on a particular linear movement key and groove for linearly moving a barrel member, thereby suppressing occurrence of a failure. The lens barrel has a fixed barrel (8) and a third lens group barrel (3). In a movement region of the third lens group barrel (3) moving in the optical direction relative to the fixed barrel (8), each of a set of a first linear movement groove (8c) and a first linear movement key (3c) and a set of a second linear movement groove (8d) and a second linear movement key (3d) has a mutually engageable region and a mutually disengageable region, and a set of a groove (8e) and a projection (3e) has not a mutually engageable region. |

Zoom lens and image pickup apparatus including the same
A zoom lens includes a first lens unit, a second lens unit, a third lens unit, a fourth lens unit and a fifth lens unit. In the zoom lens, air intervals L2w, L3w between the second lens unit and the third lens unit and between the third lens unit and the fourth lens unit at a wide-angle end, a focal length f1 of the first lens unit, a combined focal length f23w of the second lens unit and the third lens unit at the wide-angle end, a focal length fw of the whole system at the wide-angle end, a zoom ratio Z, and a smallest value L2z1a of the air interval between the second lens unit and the third lens unit in a wide angle zoom range in which a magnification-varying ratio relative to that at the wide-angle end ranges from Z0.02 to Z0.35 are appropriately set. |

Compact objective lens assembly for simultaneously imaging multiple spectral bands
An objective lens assembly suitable for use in helmet-mounted applications. The objective lens assembly comprises two prisms that collectively are configured, oriented and bonded relative to each other to separate and allow simultaneous imaging of two separate spectral bands (such as VNIR and LWIR bands) received from the same object scene via a common window such that the object scene may be viewed from the same perspective without the effects of parallax. |

Laser marked device
An optical device projecting one or more synthetically magnified images that has been laser marked with one or more static two dimensional (2D) images is provided. The static 2D image(s) laser marked on or within this device and the synthetically magnified image(s) projected by this device help determine the authenticity of a document (e.g., passport data page) or product that employs it. Several embodiments of the inventive device also offer increased resistance to tampering or alteration and wear. |
