Abstract: In one embodiment, a lidar system includes a light source configured to emit local-oscillator (LO) light and pulses of light, the emitted pulses of light including a first emitted pulse of light, where an optical frequency of the first emitted pulse of light is offset from an optical frequency of the LO light by a first frequency offset. The lidar system further includes a receiver configured to detect the LO light and a first received pulse of light, the first received pulse of light including light from the first emitted pulse of light scattered by a target located a distance from the lidar system. The receiver includes a detector, where: the LO light and the first received pulse of light are coherently mixed together at the detector, and the detector is configured to produce a photocurrent signal corresponding to the coherent mixing.

Abstract: An art surface and a method for preparing the same are disclosed. In one embodiment, a coating is disposed on a thermoplastic compatible surface of a substrate. The coating includes a reaction product of a thermoplastic, at least one cellulose fiber, and acetone. Further, the coating is able to accept one or more artistic media such as acrylic, chalk, charcoal, colored pencil, conte, dyes, egg tempera, oil, pastel, or water color, for example.

Abstract: An apparatus for removing heat caused by living embryos within an insulated hatchery enclosure. The apparatus comprises an enclosed chamber bounded by two pairs of opposing side walls and opposing first and second end walls spanning the insulated hatchery enclosure. The first end wall has a heat conductive portion, such as a copper plate, adapted to conduct heat between an outer surface of the end wall facing an interior of the insulated enclosure and an inner surface of the end wall adjacent the enclosed chamber. A plurality of baffles within the chamber define a serpentine path within the chamber through which air is directed from a start position along the path to an end position. A fresh air inlet coupled to the start position communicates fresh air taken from outside the insulated enclosure into the chamber and then through the serpentine path.

Abstract: An egg tray is provided which holds the eggs at an angle of approximately 35.degree. relative to the horizontal floor of the tray with the large or air-cell end of the egg being elevated. Air vents in the tray sides permit fresh air to flow directly over the eggs during incubation. A hatchery facility includes racks for holding a plurality of such trays loaded with eggs. The loaded racks and are rolled into an incubation and hatching chamber through a first set of doors which connect the chamber to a first hallway in which fresh air is circulated. After incubation and hatching, the racks and an air control unit in each chamber are removed through a second set of doors into a second hallway in which air from the chambers is vented during incubation and hatching. The air pressure in the first hallway is greater than that in the second hallway thereby minimizing the risk of contamination.

Abstract: An incubator for incubating and hatching eggs includes a removable air control unit for humidifying, heating or cooling, and circulating air in the incubator. The air control unit is positioned between a pair of racks containing egg trays with removable inserts to accommodate differently sized eggs. Sensors monitor various parameters such as temperature and relative humidity. A computer controls the air control unit to maintain operator-selected values of the sensed parameters.

Abstract: This invention relates to an improved apparatus and method for locking printing plates to a support, e.g., saddle or cylinder, wherein the support includes a body portion having at least two anchoring means as an integral part thereof, at least one of the anchoring means being incorporated on a spring-mounted bar movable under spring tension to engage and lock printing plates to the support. The invention also relates to apparatus and method for mounting printing plates onto a support comprising an actuating assembly for the spring-mounted bar and which is adapted to move the spring-mounted bar between expanded and compressed positions for the mounting. The spring-mounted bar actuating assembly is mounted beneath the peripheral surface of the support and comprises a pivot arm pivotable at or near its midpoint about a pivot block which is mounted beneath the peripheral surface.
