Abstract: A locking cap and container is provided for a container having an opening surrounded by a neck with container threads thereon that are sized and located to threadingly engage cap threads formed on a skirt of the cap. A shaped distal end is formed on a distal end of the container threads and a barb is formed on the distal end of the cap threads. A resilient locking tab extends from the container, and is located below the shaped distal end and spaced apart from the shaped distal end a distance sufficient to allow passage of the barb beyond the shaped distal end but sufficiently close to resiliently urge the barb into overlapping rotational alignment with the shaped end. The shaped end is configured to lockingly engage the barb when the tab holds them in alignment. Pushing down on the cap pushes the thread against the locking tab and allows disengagement of the barb from the shaped distal end and movement of the barb past the shaped distal end to unlock the cap.

Abstract: A real time embedded video processing system includes a central processing unit (CPU); a real time operating system; and an input/output interface that receives user input via a user input device. The system runs a graphics application that generates computer graphics in response to user input. A device control application controls multiple different video input sources in response to user input. The system includes a video processing engine comprising a dedicated logic circuit, such as a field programmable gate array (FPGA). The circuit includes a pixel processing engine that receives input from at least one of the video input sources and receives computer graphics from the graphics application. The pixel processing engine alpha blends the computer graphics with the video input and then outputs the blended data in real time.

Abstract: The drying time of a piece of wood can be determined by the present apparatus and method, based on a current signal passing through the piece of wood. A set of first and second electrodes of a probe are inserted into the piece of wood which may be travelling on a conveyor. The second electrode has an input for receiving electric power. The first electrode has an output for transmission of the current signal having passed through the piece of wood. The probe is driven toward and away from the piece of wood by a driving mechanism controlled by a control circuit. A measuring circuit is coupled to the outputs of the electrodes. The current signals are measured by the measuring circuit, which determines the drying time of the piece of wood.

Abstract: A method of seismic exploration by which substantially plane or substantially cylindrical seismic energy waves are simulated by combining reflectional signal traces of conventional spherical seismic waves. Seismic sources and receivers are established in sets at positions such that at least one of the sets includes a plurality of positions spaced over an extent of the area being explored having either one or two dimensions which are large relative to a seismic energy wavelength. Seismic energy is imparted into the earth from the sources and signals are generated in response to seismic energy received at the receivers. The generated signals are then combined into a form simulating the reflection response of the earth to seismic energy having a substantially continuous wavefront in either one dimension, simulating a cylindrical seismic energy wave, or two dimensions, simulating a plane seismic wave.

Abstract: A kit for assembling a toolbox adapted for installation in the back of a pickup truck, the kit containing: a preassembled upper section, an unassembled lower section, and fasteners for fastening the upper section to the lower section, when assembled. The interrelatable parts of the unassembled lower section include: a bottom panel, a pair of end panels, a pair of side panels, and four locking members. The end and side panels carry tabs for interconnecting with corresponding slots on the bottom panel. Adjacent side edges of the end and side panels have abutting locking channels which are slidingly interlocked by the locking members.

Abstract: Seismic sources and detectors are each positioned in a series of shotholes along a course to be explored. The sources in the shotholes are activated in a sequence along the course and caused to emit seismic waves. The detectors remaining along the course sense or detect the seismic waves which are then recorded. Since the detector at each shothole has performed its function, that of sensing signals from earlier shots in the sequence, its disposal by destruction when the source in the shothole with it is activated does not impair further surveying efforts.

Abstract: Seismic traces synthesizing the response of subsurface formations to a cylindrical or plane wave are obtained for a succession of shotpoint locations along a seismic line of profile. The traces obtained are then wavefront steered and the steered traces and original trace for each shotpoint are summed. Groups of these traces for a line of profile are assembled to form a steered section. A number of these sections are then individually imaged or migrated, and the migrated sections are summed to form a migrated two-dimensional stack of data from cylindrical or plane wave exploration. Reflectors may then be located by finding common tangents.The traces for those shotpoints of the several lines which lie in planes perpendicular to the lines are then assembled and processed in the foregoing manner to obtain three dimension migrated seismic data.

Abstract: Seismic sources or source arrays and seismic detectors or detector groups are arranged and spaced with respect to each other during the seismic survey to enhance simulation of plane waves or cylindrical waves, and also to reduce undesirable effects of horizontally travelling seismic noise.

Abstract: A seismic signal source adaptable for use with various types of seismic exploration vehicles which move over land. A signal means forms a seismic signal, and a transfer means transfers the signal to a fluid-filled tire of the vehicle for improved and more efficient coupling of the signal to the ground surface. Whether the vehicle with which the source is mounted is stationary or moving, signals may be sent from the source into the ground.

Abstract: A new and improved method of forming color graphic displays from input data is disclosed. In the displays so formed differing colors quantitatively identify and indicate differing values or ranges of values of the data. The input data are processed to determine sample values for data display points, and numerical codes from an assignment table are assigned according to the sample values. The assigned codes are arranged into output sequences for each of plural component displays of the final display, and the component displays formed and displayed in superposition to form the color graphic display with colors therein graphically indicating the data.

Abstract: A synthetic display is provided, in cross-sectional form, of the theoretical strength of seismic reflections. The theoretical strength is computed from calculated inverval-velocity values and known or estimated density values. By comparison of this synthetic reflection-strength display with the observed reflection-strength display, useful conclusions may be drawn about the nature of geological materials and the complex origin of reflections.

Abstract: New and improved apparatus and method for seismic exploration on land transports sensing geophones with a flat, lightweight, towing medium or sheet which conforms to the earth's surface. The geophones are mounted on sleds attached to the towing medium by strips or members of resilient material which isolate and decouple the geophone from vibrations and the like induced, sensed, or transmitted by the towing medium. The resilient members enable the geophones and sleds to continually maintain contact with the earth's surface over irregularities in the surface to provide good ground coupling for more accurate seismic exploration results. Plural or multiple towing mediums may be coupled together and towed into place for use in accordance with the desired geophone array to be used.
