  • Patent number: 7662787
    Abstract: The present invention describes compounds, compositions and methods of using the same comprising lysine covalently attached to amphetamine. These compounds and compositions are useful for reducing or preventing abuse and overdose of amphetamine. These compounds and compositions find particular use in providing an abuse-resistant alternative treatment for certain disorders, such as attention deficit hyperactivity disorder (ADHD), ADD, narcolepsy, and obesity. Oral bioavailability of amphetamine is maintained at therapeutically useful doses. At higher doses bioavailability is substantially reduced, thereby providing a method of reducing oral abuse liability. Further, compounds and compositions of the invention decrease the bioavailability of amphetamine by parenteral routes, such as intravenous or intranasal administration, further limiting their abuse liability.

  • Patent number: 7661381
    Abstract: A vehicle includes a submersible housing and a propulsion mechanism, which is coupled to drive the housing over an interior surface of a container in which the housing is submerged. A hollow tube is fixed to the housing and is configured to be filled with a fluid having a first specific gravity. One or more objects, which have a second specific gravity that is less than the first specific gravity, are contained within and capable of moving inside the hollow tube so as to stabilize the housing in response to changes of an angle of the interior surface over which the vehicle travels.

  • Patent number: 7659311
    Abstract: The inventors have discovered that the disodium salt of certain delivery agents has surprisingly greater efficacy for delivering active agents than the corresponding monosodium salt. Furthermore, the inventors have discovered that the disodium salts of these delivery agents form solvates with ethanol and hydrates with water. The delivery agents have the formula wherein R1, R2, R3, and R4 are independently hydrogen, halogen, C1-C4 alkyl, or C1-C4 alkoxy; and R5 is a substituted or unsubstituted C2-C16 alkylene, substituted or unsubstituted C2-C16 alkenylene, substituted or unsubstituted C1-C12 alkyl(arylene), or substituted or unsubstituted aryl(C1-C12 alkylene). The hydrates and solvates of present invention also have surprisingly greater efficacy for delivering active agents, such as heparin and calcitonin, than their corresponding monosodium salts and free acids. The present invention provides an alcohol solvate, such as ethanol solvate, of a disodium salt of a delivery agent of the formula above.

  • Patent number: 7660090
    Abstract: A circuit for voltage transient protection is provided. The circuit includes a voltage divider, a low-voltage reset circuit, and an input transistor. The input transistor receives an input voltage at the source of the input transistor, and provides a protected input voltage at the drain of the input transistor. The voltage divider provides a threshold voltage from the input voltage. The low-voltage reset circuit receives the threshold voltage. The low-voltage reset circuit causes the gate and source of the input transistor to short together when the low-voltage reset circuit is not in a reset state.

  • Patent number: 7660035
    Abstract: A scanning microscope includes at least one light source, an acousto-optical element, a beam deflection device and a beam guiding device. The at least one light source generates an illuminating light beam. The acousto-optical element spatially splits a sub-light beam from the illuminating light beam and adjusts an optical power of the illuminating light beam. The beam deflection device scans the illuminating light beam over or through a sample. The beam guiding device directs the sub-light beam onto the sample.

  • Patent number: 7658175
    Abstract: An engine start device having a first start mode in which the engine is started on a spot by executing a start operation of the engine, and a second start mode in which a necessary accumulated force is previously accumulated in to start in one time in an optional place at an optional timing. In the first start mode, an accumulated force, accumulated by a rotation of a rotation drive section allows the engine to be started on the spot. If switched to the second start mode, the rotation of the rotation drive section is exclusively accumulated and released in the optional place at a desired time so as to start the engine in accordance with a one-touch operation.
