Abstract: A seismic gun system for surveying underground geological topology, the seismic gun system comprising a projectile, a seismic gun body, a barrel, and a guide tube. The projectile includes an outer tubular jacket and a frangible material in its interior. A exterior surface of the tubular jacket is textured to regulate tubular jacket disruption. The barrel includes a breach end and a muzzle end. The breach end is connectable to the seismic gun body for receiving the projectile into said barrel and said muzzle end directing the projectile towards the bottom of a bore hole. The guide tube has an upper end and a terminal end. The upper end of the guide tube is connectable to the muzzle end of the barrel. The guide tube has walls to direct the projectile towards the bottom of the bore hole when aimed therein.

Abstract: A light weight brake assembly for bicycles is disclosed. Some embodiments of the invention are designed to enhance assembly adjustability, for example to accommodate geometric variations that occur with various bicycle frame and wheel geometries. Some embodiments of the invention are designed to allow for a brake leverage that can be non-linear and capable of multiplying during brake actuation so that braking force increases more rapidly than brake lever force applied by the user. Some embodiments of the invention are designed to provide a brake sensitivity that is adjustable in use. Some embodiments provide for a quick-release functionality, for example by quickly increasing the gap between the two brake pads so that the wheel can be easily/quickly removed.

Abstract: A well drilling head comprises a housing and a bearing assembly. The housing has a sidewall structure defining a central bore. A tapered bearing assembly seating surface is provided within the central bore of the housing. The bearing assembly includes an outer barrel having a central bore, an inner barrel at least partially disposed within the central bore of the outer barrel and bearing units coupled between the barrels for providing concentric alignment of the barrels and allowing rotation therebetween. The outer barrel is removably seated within the central bore of the housing. A tapered exterior surface of the outer barrel is engaged with the tapered bearing assembly seating surface of the housing whereby engagement of the tapered surfaces align the outer barrel with respect to the central bore of the housing.

Abstract: A reinforced stripper rubber assembly with a stripper rubber body including a drillstring engaging portion having a drillstring bore extending axially therethrough. The drillstring engaging portion of the stripper rubber body is made from an elastomeric material, has an inner surface that engages a drillstring when the drillstring is dispose therein and has a reinforcing insert receiving recess within an exterior surface thereof extending at least partially around the drillstring bore. A reinforcing insert is disposed within the reinforcing insert receiving recess. The reinforcing insert includes an elastomeric material bonded to the stripper rubber body within the reinforcing insert receiving recess. A support structure is disposed within a support structure engaging portion of the stripper rubber body. The support structure includes a central opening generally aligned with the drillstring bore thereby allowing the drillstring to pass jointly through the central opening and the drillstring bore.

Abstract: An image processing system and method is disclosed. The image processing system can be configured for use with a mouse scanner system operable to scan a document. The mouse scanner system includes a scanner built into a computer mouse and the image processing system includes a scanner software application operating on a computer. The scanner includes a positioning system operable to output position indicating data and an imaging system operable to output captured image data. The data is sent to the scanner software application where a feedback image is constructed and displayed on a display in real, or near real, time to allow the user to view what areas have been scanned. The scanner software application also constructs an output image that can be printed, saved or communicated.

Abstract: Pedicle screw apparatuses each including a pedicle screw assembly and an attached pedicle screw extender are placed in a true percutaneous manner, thereby overcoming issues resulting from placing pedicle screw assemblies through a retractor. Thus, a retractor can advantageously be built off of the pedicle screw apparatuses, thereby allowing visualization of the spine anatomy directly. Furthermore, such a method for performing surgery ensures ideal placement of the retractor for additional procedures that are often required such as, for example, decompression, interbody device placement, etc.

Abstract: A gunfire shock simulation apparatus that uses an actual firearm for generating and measuring shock response data without a pyrotechnic discharge. The apparatus exerts an impact on a discharge end of a barrel of the firearm for simulating the pyrotechnic discharge event of a round of ammunition discharged within the firearm. Following such impact, the apparatus cycles a bolt carrier group of the firearm for simulating movement of the bolt carrier group resulting from the pyrotechnic discharge event of a round of ammunition. A sensing device is used for gathering shock response data in three perpendicular reference axes. By adjusting the manner in which the impact is applied to the discharge end of the barrel and/or the manner in which the bolt carrier group is cycled, resulting shock response data can be tuned to closely approximate that generated by live fire of the firearm.

Abstract: A blade assembly has a blade body and a blade body surround. A retractor attachment structure is attached to the blade body at the first end portion thereof extending from an exterior surface thereof. The retractor attachment structure is configured for having one of the blade body mounting structures of the retractor engaged therewith in a manner whereby the blade body is independently pivotable about and translatable along the blade body mounting structure. An alignment member protrudes from an interior surface of the blade body adjacent its first end portion. A slot extends through the blade body at its first end portion. The blade body surround and the blade body jointly form a generally cylindrical-shaped structure when the blade body is in a seated position within the slot. The cylindrical structure defines a central passage extending between the first and second end portions of blade body surround.

Abstract: A seismic gun assembly comprising a barrel and guide tube assembly for delivering a projectile to the bottom of a bore hole with a non-line-of-sight section. The guide tube being either a large diameter guide tube or a tight fitted guide tube. The large diameter guide tube allowing the projectile to perform shallow angle bounces to reach the bottom of a non-line-of-sight bore hole. The tight fitted guide tube allows the projectile to ride the inner wall of the guide tube to reach the bottom of a non-line-of-sight bore hole. The projectile comprises an outer jacket and a frangible core. The seismic gun barrel assembly additionally comprises a fluid exclusion puck for preventing fluids from entering the guide tube, a suppressing collar for suppressing seismic noise, and a method for modulating recoil.
