  • Patent number: 8931415
    Abstract: Initiator systems for warheads include a first initiation device configured to detonate at least a portion of an explosive material contained in an explosive device and a second initiation device configured to deflagrate at least a portion of an explosive material of a warhead. Scalable output explosive devices include an explosive material at least partially disposed within a housing and an initiator system including a first initiation device configured to detonate at least a portion of the explosive material and a second initiation device configured to deflagrate at least another portion of the explosive material. Methods of igniting warheads include deflagrating a portion of an explosive material disposed within the warhead and detonating at least another portion of the explosive material disposed within the warhead.

  • Patent number: 8887430
    Abstract: Subject matter disclosed herein relates to an apparatus, device, or method for detecting aim or pointing direction of a firearm, the method comprising detecting a sound signature of a gunshot from the firearm; sensing an aim direction of the firearm substantially at the time of detecting the sound signature of the gunshot; setting a reference direction based, at least in part, on the aim direction; sensing a current aim direction of the firearm; comparing the current aim direction to the reference direction; and initiating an alarm if the current aim direction is beyond a threshold angle of displacement from the reference direction.

  • Patent number: 8132537
    Abstract: A multi-compartment pet training system includes a front compartment joined to a rear compartment to define a passage therebetween such that the pet may move freely between the front compartment and the rear compartment. The front compartment includes a front door for ingress and egress of the pet between a surrounding area and the front compartment. The front compartment provides an area in which the pet may eat, drink and sleep. The rear compartment is configured to allow the pet to carry out urinary and/or fecal elimination while its owner is away. As such, the pet may be trained to utilize the rear compartment for carrying out waste elimination activities while utilizing the front compartment for all other activities.

  • Patent number: 6752357
    Abstract: An aircraft distance measuring system analyzes images from at least one camera using a known refueling boom length and boom nozzle location to identify a distance between the boom nozzle and a receiving aircraft refueling receptacle. Existing sensors identify boom extended length and angle. The refueling boom and camera connection points on the refueling aircraft provide reference points. Each camera takes a plurality of images of the boom nozzle and the refueling receptacle which are converted to pixel images. A plurality of different aircraft are stored as wire-models in a computer. The computer compares the receiving aircraft image to the wire-model images and a receiving aircraft type having a known refueling receptacle position is selected. The computer continuously uses the camera images and analyzes for position, range and aspect to continuously calculate (i.e., update) the distance between the boom nozzle and the receiving aircraft refueling receptacle.

  • Patent number: 6739084
    Abstract: A fishing rod rack for the support of a plurality of fishing rods, the fishing rod rack spanning the width of the bed of a pick up truck. The fishing rod rack has a two piece bracket member at each end for engaging the inward lip of the respective side walls, there being a support rod extending between opposing bracket members. A plurality of support tubes are rotatably secured to the support rod by a clasp member rotatable about the support rod and secured in angular position by a pair of set screws.

  • Patent number: 6732470
    Abstract: A first horizontal hollow cylinder open at both ends has a first narrow elongated slot. A second horizontal hollow cylinder open at both ends is disposed concentrically within the firtst cylinder and has a second narrow elongated slot that extends between its ends. A vertically elongated element is secured at its upper end to the first cylinder and has an opening intermediate its ends. A flexible elongated connector secured at one end to the lower end of the element with its other end being detachable with the element opening. A rotatable member is secured to one end of the second cylinder and is spaced from the first cylinder so that the member can rotate the second cylinder about its axis without rotating the first cylinder.

  • Patent number: 6684578
    Abstract: A method for controlling the spread of kudzu utilizes vertical, or near vertical, smooth surfaces which do not provide a horizontal step for continued vertical growth of kudzu. Accordingly, a clear zone may be established mechanically or otherwise and guards placed intermediate the kudzu and an area to be protected wherein when the vines contact the guards, they are unable to unsupportedly span the guard to continue upward growth and then into the protected area.

  • Patent number: 5451076
    Abstract: A pneumatic actuator for a trailer landing gear reduction assembly for directing the raising or lowering of the feet of a trailer. The pneumatic actuator replaces the hand crank which has traditionally been used for turning a gear reduction assembly of the trailer. The present invention can be incorporated onto the already existing trailer landing gear or the present invention can be milled directly onto the newly manufactured trailer.

  • Patent number: 5287949
    Abstract: A shaft-locking device which locks rotation of a movable shaft by a clamping force of a coil spring closely surrounding a fixed shaft and a movable shaft. Both sides of the coil spring are inserted surrounding the fixed shaft and a central portion of the coil spring surrounds the movable shaft. In case of rotation of the movable shaft on both sides, the locking torque is applied. Further, the closed state of the coil spring to the movable shaft is maintained uniformly without any relation to operation by separating the end portions of the coil spring at the movable shaft side of the coil spring from an outer circumference of the movable shaft so that a constant locking torque may be always obtained.
