  • Patent number: 7448532
    Abstract: The present invention discloses a log sawing system comprising multiple cutting blades. The multiple cutting blades are positioned to cut laterally or perpendicular to the centerline of the log which is to be cut. The logs are transported into cutting position using some type of log positioner. The multiple cutting blades are rotatably mounted on an arm which is pivotally mounted on a shaft in groups, being driven by an electrical or like motor, all of which are mounted onto a platform positioned adjacent to the log to be cut. Hydraulic lifters are used to partially rotate the saw blades into the cutting position adjacent the log. Means utilizing a computer and lasers are provided to develop a log cutting solution to best utilize the logs.

  • Publication number: 20080262366
    Abstract: A method and apparatus for measuring the QT interval of an electrocardiogram (ECG) signal is provided wherein the end of the T wave is identified from ECG data. The end of the T wave is defined as the first time of intersection at which an upright T wave of a first set of derived ECG signal data intersects an inverted T wave of a second set of derived ECG signal data. The intersection of the two sets of ECG data is along an isoelectric line within the trough after the positive T wave peak when the superimposed isoelectric baselines from the upright and inverted ECG signals demonstrate the best least squares fit.

  • Publication number: 20080169229
    Abstract: Circulation systems for ponds, lakes, or other bodies of water. In one set of embodiments, water is drawn up from the depths of the body for exposure to the atmosphere and to generate an overall, high flow circulation pattern throughout the entire body. In other embodiments, the circulation in the body of water is primarily limited to an upper aerobic zone with only small and controlled volumes from a lower anaerobic zone being brought up. Each system preferably includes a flotation platform, dish, impeller, and draft tube with specific modifications to the various systems to adapt them for use in a variety of environments.

  • Publication number: 20080087610
    Abstract: Circulation systems for ponds, lakes, or other bodies of water using a flotation platform, dish, and impeller. One embodiment has a connecting arrangement between the drive motor and the impeller that permits the two to be easily and quickly coupled and uncoupled. The connecting arrangement also is designed to accommodate slight misalignments between the shafts. An arrangement to adjust and calibrate the depth of the inlet to the draft tube is disclosed. The system further includes solar panels that can be pivotally swung outwardly to open positions, angularly adjusted about a horizontal axis, and mounted to face toward the central axis of the flotation platform rather than away from it. Arrangements are further provided to monitor and control the components of the system including remotely from shore.

  • Publication number: 20070295672
    Abstract: A circulation system for bodies of water. In one set of embodiments for larger bodies of water, modified horizontal plate designs are provided at the entrance of the draft hose. The plate designs have sections that pivot downwardly as the flotation platform and depending draft hose are rapidly raised in high wave conditions to let the water escape downwardly out of the hose. Adaptations to the floats for the elongated arms of the platform are also made to essentially eliminate the creation of any damaging torques on them from high waves. Another set of embodiments are particularly adapted for smaller systems in municipal water tanks for thorough mixing of the water and treatment to kill undesirable ammonia oxidizing bacteria and prevent or at least inhibit their return.

  • Patent number: 7152728
    Abstract: The present invention 10 discloses a device for singulating individual logs from groups of logs for linear or transverse processing. The present invention discloses a log singulator having a fully rotatable lifter arm member, i.e., 360 degrees rotatable, which is used to singulate logs from groups of logs. The rotatable axle of the lifter arm may be located above the upstream “V” of the log cradle member. Furthermore, the lifter arm of the present invention will positively push the logs over the top point of the log cradle because it is rounded at the top point, thereby allowing the tip of lifter arm to remain in contact with the log. Lifter arms with 1 to 4 lifter arm tips are disclosed.

  • Patent number: 6956333
    Abstract: This invention relates to a device for emitting addressable locations comprises parallel spaced-apart first conductors (10) intersecting with parallel spaced-apart second conductors (11). The intersecting first and second conductors define addressable locations where electrons (12) are emitted in response to the application of an energizing voltage. One face of the first conductors is covered with an insulating layer (13) against which the second conductors (11) are applied, this insulating layer (13) forming a tunnel barrier for hot electrons (12) that travel ballistically through and are emitted from the second conductors (11) in response to the application of the energizing voltage. The emitted electrons impinge a target (30, 40, 50) which can be a light-emitting screen of a flat panel display, such as an electroluminescent polymer of a flat panel screen, or an electroluminescent phosphorous screen, or a target wafer bombarded by the electrons emitted from a flexible e-beam lithography mask.
