  • Patent number: 10066914
    Abstract: A disposable indicator for use with an arrow or crossbow bolt comprising a substrate and a chemical indicator material capable of detecting and visually indicating chemical properties of a bodily fluid wiped from the arrow by a change in color. Chemical indicating materials may be selected to indicates a variety of bodily fluid chemical properties using pH, enzyme, or detection of other bodily compounds. The indicator provides an immediate indication of the portions of the animal's body through which the arrow or bolt passed, enabling the hunter to determine the type of shot and how best to track the wounded animal. An additional benefit is that the substrate can be used to clean the arrow or bolt in additional to providing a chemical shot indication.

  • Patent number: 9833612
    Abstract: Various examples are provided for securing deep brain stimulation (DBS) leads. In one example, among others, a DBS cap for securing a DBS lead includes a base ring adapted to be mounted within a counterbore opening formed in the skull, a lead securing element that mounts to the base ring, and. a top cover that mounts to the base ring. In another example, a method for securing a DBS lead includes forming a counterbore opening in the skull, securing a DBS cap within the counterbore opening, passing a DBS lead through the DBS cap and the counterbore opening and positioning a tip of the lead in brain tissue, and securing the DBS lead to the DBS cap using an adhesive. The skull opening includes a lower bore, a concentric upper bore, and a step positioned at the interface of the upper and lower bores.

  • Patent number: 9767552
    Abstract: In one embodiment, the presence of anomalous material within tissue is detected by scanning a patient using magnetic resonance imaging (MRI) to obtain MRI data, identifying individual voxels of the MRI data, identifying multiple parameters of each voxel, and determining as to each voxel based upon the identified parameters the likelihood of tissue represented by the voxel containing anomalous material.

  • Patent number: 9759534
    Abstract: An arrow or bolt comprising of an indicator that will chemically indicate the fluids that have come into contact with the arrow as it has passed through the animal. The indicator may comprise a treated substrate that chemically reacts with bodily fluids of the animal as the arrow or bolt passes through the animal to provide an indication of the acidity thereof. The chemical indicator may be attached to the arrow allowing a user to reuse the arrow by simply removing a used indicator and replacing with an unused chemical indicator. Alternatively, a portion of the arrow or bolt may be provided with an absorptive neutral substrate on which a reusable chemical indicator dye could be applied. The substrate could be cleaned following use and the indicator dye reapplied to enable reuse of the arrow or bolt.

  • Patent number: 6169359
    Abstract: The luminance of a phosphor suitable for an alternating current thin-film electroluminescent device is substantially improved according to the present invention by including an alkali halide. The alkali halide included within the bulk of the phosphor material results in providing a significant number of trapping states which trap free electrons within the phosphor material. The addition of the trapping states (added defects) within the bulk tend to control the electrical and optical characteristics of the phosphor material. This reduces asymmetric light output characteristics of traditional phosphor material, reduces asymmetric current movement within the phosphor material, and decreases the influence of the interfaces between the phosphor material and insulating materials resulting in decreased aging and increased brightness.
