Abstract: A coating removal apparatus removes a coating from a surface. The apparatus has a movable scanning head and scanning optics. The scanning head is movable in one dimension, and the scanning optics adjust in two dimensions to compensate for movement of the scanning head to implement long range scanning with a uniform scanning pattern. Further, a surface roughness is determined by measuring specular and scattered reflections at various angles. For composite surfaces, the apparatus utilizes UV laser radiation and a controlled atmosphere to remove coating and alter the chemical characteristics at the surface.

Abstract: A system to optimize code for a family of related functions. The system recognizes a function call as being a member of a family of related functions. For the member function, the system replaces the member call with corresponding family-start and member-finish function calls.

Abstract: A rotary refractive laser scanner head uses two sets of lenses and prisms aligned along a common optical axis. Each prism is paired with one of the lenses. The lens-prism pairs are separately mounted rotatable on a common axis coaxial with the optical axis. A motor drives two gear sets. Each gear set is separately coupled to one of the two lens-prism pairs and rotates them at selected, typically different speeds. An input laser beam is directed along the optical axis at one of the lens-prism pairs. The first pair collimates and refracts the input beam into an intermediate deflected beam according to Snell's law and the characteristics of the laser beam and optics. The second pair receives the intermediate beam and further deflects it to form an output beam. By selecting the motor speed, gear ratios, optics spacing, characteristics and prism wedge (deflection) angle, the scanner head effectively can scan an output laser beam over a desired pattern area.

Abstract: A golf club organizing assembly for a golf club carrying bag includes a plurality of dividers. Some of the dividers extend in intersecting transverse relationships with other of the dividers so as to form a plurality of compartments therebetween for receiving shafts of golf clubs placed in a carrying bag. Also, some dividers are of colors different from and contrasting with colors of other dividers so as to provide contrasting colors about the compartments which improve visibility of compartments to a golfer over a case where all of the dividers are of the same color.

Abstract: A method and system for treating internal surface material overlying the interior of a tubular a substrate, and more particularly, to a system for ablating contaminates and other unwanted material from an internal surface 52 using a pulsed laser beam (38). The system includes three main sub-systems: a back end (30), a work head (100), and an umbilical tube (31) to protect conduits communicating between the back end (30) and the work head (100). The back end (30) includes heavy and bulky equipment such as a laser (32), chiller (4), pressurized air source (70), suction system (84), waste containment system (82), and electric power source (78). A conveyance such as a trailer (17) may enclose the back end (30) to make it transportable. The work head (100) includes a propeller driven rotating mirror assembly (380), and a lens assembly (520). During operation, the work head (100) is inserted in the tube or pipe and the laser (32) activated.

Abstract: In accordance with the present invention, a method is disclosed herein which is primarily designed for use in improving the seismic data collection process through the use of hybrid gathers. The instant invention is suitable for application either in the field during seismic acquisition as part of the process or back at the main processing center, although it will probably be of greatest use in the field. That being said, the computational efficiency of the instant method and its ability to work effectively with low fold seismic data sets argue that it would be most useful in the field. By timely application of the instant method it is possible to improve or optimize the selection of acquisition parameters such as geophone spacing, line layouts, shot locations, instrument filters, etc., while the data are being acquired.

Abstract: This invention relates to the general subject of seismic exploration and, in particular, to seismic processing and methods for attenuating ground roll in land and ocean bottom seismic surveys. According to a first aspect of the instant invention, there is provided a method of attenuating non-primary reflection events such as ground roll in an unstacked gather. In the preferred embodiment, the collected seismic data will be analyzed to determine the approximate velocity at which the ground roll appears to travel through the section. As a next step, a single-velocity migration is performed on the seismic data at the selected velocity. Those seismic events that are moved by the migration past an “attenuation line” on the section are intentionally discarded or attenuated. Finally, a reverse single velocity migration is performed which places the reflectors—minus those events such as ground roll that have been attenuated—back at their original unmigrated times.

Abstract: An improved method for gathering traces in a 3-D seismic survey is disclosed. In one configuration, receiver lines having equally spaced geophone receivers stations are run in one direction, and lines of equally spaced shotpoint stations run orthogonal to the receiver station lines. The station spacing in each shotpoint and receiver lines is selected to produce a desired spatial resolution, and the individual lines are spaced apart by a distance equal to at least two times the station intervals. In this method, a series of common mid point gathers centered about source/receiver line intersection, referred to as "hybrid gathers" is made, where each hybrid gather includes traces from a designated number of shots in the shotpoint line of the selected intersection that are directed into a designated number of geophone receivers in the receiver line of the selected intersection.

Abstract: An HMDS tank for use in an integrated circuit fabrication process includes a tank configured to hold HMDS having an first inlet port configured to receive a carrier gas below an HMDS surface level, an outlet port configured to release said carrier gas saturated with HMDS above the HMDS surface level, and a second inlet port configured to receive HMDS. A sensor is positioned in the tank at a predetermined HMDS level and configured to generate a sensor signal when the HMDS surface level falls below the predetermined HMDS level. A processor is coupled to the sensor and configured to generate a fill signal in response to the sensor signal to initiate introduction of HMDS into the tank through the second inlet port. In another embodiment, the HMDS tank further includes a second sensor positioned in the tank at a low HMDS level. The processor is also coupled to the second sensor and configured to generate an alarm signal in response to the second sensor signal to warn an operator of a low HMDS level in the tank.

Abstract: Incoming diphase signals E which have base bit intervals delineated by spaced clocking signals with data information occurring between the clocking signals are fed to a four bit shift register 10 which in cooperation with an exclusive OR-gate 14 generates a pulse D for each diphase signal E transition. Upon receipt of a preamble comprising four diphase signal transitions, a shift register 16 provides a signal MSR which initiates the decoding of the following data information. A counter 24 stores counts related to the time intervals between each two successive clocking signals and counters 26 and 28 store a count related to an immediately subsequent time period which is three-fourths of the time interval. The occurrence of data information is sensed by a logic array 20 during successive time periods and a non-return to zero mark-space output signal K is stored in a flip-flop 22. The logic array 20 continually updates the counts stored by the counters 24, 26-28.

Abstract: A circuit for detecting the relative time of occurrence of first and second signals applied to first and second terminals includes a pair of bistable flip-flops. In response to the occurrence first of the first signal the first one of the flips-flops is set to initiate the generation of a control signal. A time delay responds to the control signal and upon expiration of the time delay interval the second one of the flip-flops is set and this in turn resets the first flip-flop to terminate the control signal. In response to the first occurrence first of the second signal the second one of the flip-flops is set and this inhibits the setting of the first flip-flop. In the event that the first and second signals occur simultaneously the second flip-flop sets quickly resetting the first flip-flop. In response to either signal, a conductive path is established between the terminals.
