Abstract: A method for distributing injection fluid in a horizontal well bore in fluid communication with hydrocarbon bearing formation begins by determining flow resistance characteristics of the formation along at least a portion of the length of the horizontal well bore. An injection tubing string having a sidewall defining a tubing bore is injected into the horizontal well bore. The tubing string is provided with ports having a selected distribution and geometry. The annulus geometry is selectively controlled along the length of the tubing string through at least one of axial distribution of eccentricity and flow area of the annulus, so as to provide selected flow restriction characteristics along the annulus, such that when injection fluid is pumped into the tubing, a resulting flow resistance network is formed by the tubing bore, the ports, the annulus and the formation, resulting in a desired distribution of the fluid into the formation.

Abstract: Disclosed is a diffractive micromirror and a method of producing the same. More particularly, the present invention pertains to a diffractive micromirror, in which a recess having a desired depth and width is precisely formed in a piezoelectric operation manner, and a method of producing the same.

Abstract: A retractable step assembly (10) includes a step (12) pinned to the lower ends of a pair of swing arms (14, 16) depending downwardly from a bracket (30) for mounting the step assembly to the underside of a vehicle. An electric motor (20) powers the upper end of a swing arm (14) to rotate the two swing arms between retracted and extended positions. A clutch assembly (24) is interposed between the electric motor and the swing arm (14) to allow the motor to continue to operate to the end of its cycle if the step or swing arm become obstructed. A lock assembly (170) is provided to lock the step in retracted position, with the lock being automatically disengaged when the step assembly is actuated to extend the step from retracted position.

Abstract: A method and apparatus for aligning an optical fiber (120) with an optoelectronic hybrid device (112) and locking the optical fiber in the aligned position are disclosed. A fiber coated with an external layer of gold is threaded through a solder preform (130). The optical fiber (120) rests upon a ceramic substrate (104). The ceramic substrate also supports a device submount (108) that houses the optoelectronic device (112). The ceramic substrate (104) supports a resistor/heater formed of a thin film of nickel-chromium alloy (604). The resistor/heater supports a pad (609) formed of a layer of nickel (610) and a layer of gold (612). Located atop the pad (609) is the solder preform (130). Precise control of heating is provided by applying a predetermined voltage to the resistor/heater (122) for precise time periods, thereby eliminating the necessity of making temperature measurements during heating. As the resistor/heater (122) is energized, the solder preform is liquefied.

Abstract: Disclosed is a flight management computer modification that provides a pilot of an aircraft with a list of alternate landing destinations at which he can land the aircraft in case of an emergency on board or due to some reason why he cannot land at an intended destination. Each of the alternate landing destinations is displayed with data regarding the distance between the aircraft's present position and each of the alternate destinations, the estimated time of arrival to fly the aircraft to each of the alternate destinations and an estimate of the fuel remaining on board the aircraft if the aircraft were to land at the alternate destinations. The data allows the pilot to compare the benefits of landing at one of the alternate destinations versus landing at another. The dam is calculated assuming a direct flight from the aircraft's present position to the alternate as well as assuming a missed approach at the intended destination and a flight from the intended destination to the alternate landing destination.
