  • Patent number: 8644595
    Abstract: In one aspect, a method of displaying data is provided. The method comprises obtaining projection data of an object by exposing an object to radiation at a plurality of view angles and detecting at least some of the radiation exiting the object to form the projection data, operating a computer to reconstruct the projection data at a reconstruction resolution to form image data comprising a plurality of voxels representing locations within the object, each of the plurality of voxels being assigned an associated intensity indicative of a density of the subject matter at the respective location, determining a maximum resolution for display, above which variation in intensity between adjacent voxels is not supported by information in the projection data, the maximum resolution being less than the reconstruction resolution, and displaying the image data at or below the maximum resolution.

  • Publication number: 20130169820
    Abstract: This invention relates to processes for the capturing of the images of a target, and/or the shooter, at the time around the discharge of a gun, bow, or shooting device and the display of the images prior to discharge, around point of discharge, and post discharge in a manner that allows the shooter to analyze the images and data. More particularly, the present invention relates to the process in shooting where a moving target must be led in order that the projectile (or projectiles) arrives on target after the point in time where the shoot decision is made and the projectile reaches the target area. This invention will aid the shooter by letting them see images and sight pictures of successful and unsuccessful shots and how much lead, if any, they had given the targets at the point in time they decided to shoot. It also allows for the shooters technique to be recorded and analyzed.

  • Patent number: 8346207
    Abstract: A location and control system automatically locates, identifies, and corrects faults on a distribution system. The fault location and control system includes a central computer connected at one end of the distribution network and one casing installed at various locations along the distribution network. Each casing encloses a radio transceiver, plus an amplitude modulation detector connected to the radio transceiver. Each casing is installed at a predetermined distance from each other. When a fault is produced in the distribution line, each of the amplitude modulation detectors adjacent to a place where the fault is produced emits a signal that is detected by the central computer. The central computer detects and compares the location of the place where the fault is produced by comparing the time of arrival of the signals. The central computer may then automatically or manually disconnect any part of the distribution network in order to extinguish the fault arc.

  • Patent number: 8071734
    Abstract: The invention relates to compositions, systems, and methods for simultaneously detecting the presence and quantity of one or more different compounds in a sample using aptamer beacons. Aptamer beacons are oligonucleotides that have a binding region that can bind to a non-nucleotide target molecule, such as a protein, a steroid, or an inorganic molecule. New aptamer beacons having binding regions configured to bind to different target molecules can be used in solution-based and solid, array-based systems. The aptamer beacons can be attached to solid supports, e.g., at different predetermined points in two-dimensional arrays. The invention includes devices, methods, and computer software for carrying out the methods.

  • Patent number: 7971062
    Abstract: A hand-held token for secure conveyance of encryption keys includes memory for holding a media key and at least one device key. Control logic reads the media key from memory, encrypts the media key based on the device key, and transmits the encrypted media key to a data storage device. The data storage device decrypts the encrypted media key using its own device key, which may have previously been downloaded from a token.

  • Patent number: 7817773
    Abstract: A method and apparatus for imaging an object including the steps of projecting radiation from a radiation source through an object and moving the radiation source through multiple imaging positions relative to the object without stopping movement of the radiation source. Movement is accomplished while projecting radiation at more than one of the imagining positions with the source having a source velocity for at least one imaging position that is different from a source velocity for a second imaging position. Radiation transmitted through the object is also detected. Radiation may be projected while moving the radiation source through the multiple imaging positions. In addition, the velocity at which the radiation source is moved through a select imaging position may be related to a resolution desired for data collection at the select imaging position. The velocity of the radiation source may be varied within a select imaging position.

  • Patent number: 7797751
    Abstract: A multiple field nonce particularly suited for use in encryption algorithms associated with data storage has at least one field unique to each data storage device to avoid the possibility of the same nonce value being used to store more than one data string. Additional fields may be based on the number of times at least one encryption key is associated with the storage device and on a number assigned to the particular string of data.

  • Patent number: 7706538
    Abstract: A system, method and data storage device for encrypting data to provide at-rest data encryption of data in the data storage device. The system includes a compression engine for receiving a host data stream packet and selectively generating a compressed data packet, and an encryption engine in electronic communication with the compression engine for receiving an unencrypted data packet from the compression engine. The unencrypted data packet comprises the compressed data packet when the compression engine generates the compressed data packet. The unencrypted data packet comprises the host data packet when the compression engine does not generate the compressed data packet. The encryption engine generates an encrypted data packet having an encrypted component corresponding to the unencrypted data packet and a set of meta data indicative of one or more characteristic of the encrypted data packet.
