  • Patent number: 8278327
    Abstract: Compounds that inhibit PDE10 are disclosed that have utility in the treatment of a variety of conditions, including (but not limited to) psychotic, anxiety, movement disorders and/or neurological disorders such as Parkinson's disease, Huntington's disease, Alzheimer's disease, encephalitis, phobias, epilepsy, aphasia, Bell's palsy, cerebral palsy, sleep disorders, pain, Tourette syndrome, schizophrenia, delusional disorders, drug-induced psychosis and panic and obsessive-compulsive disorders. The compounds have the general structure: wherein m, n, p, x, R, R1, R2, R3, R4, R5, A and B, are defined herein, including pharmaceutically acceptable salts, stereoisomers, solvates or prodrugs thereof. Also disclosed are compositions containing a compound of this invention in combination with a pharmaceutically acceptable carrier, as well as methods relating to the use thereof for inhibiting PDE10 in a warm-blooded animal in need of the same.
    Type: Grant

    Date of Patent: October 2, 2012
    Assignee: Omeros Corporation

  • Patent number: 8066859
    Abstract: A sensor supervision system for periodically providing a test to accesses the status of a gas detection sensor, such as a carbon monoxide (CO) sensor, is provided. To access the status of the CO sensor, a processor provides a voltage to the sensor supervision system, such that a voltage is applied to CO sensor, charging the CO sensor. The status of the CO sensor is accessed by determining the change in the voltage charge of the CO sensor between two sampling time points. If the first sample voltage is substantially equal to the second sample voltage, i.e., a substantially constant voltage, the carbon monoxide sensor fails the test. However, if there is an change is the voltage change between the first and second sampled time points, the CO sensor passes the test.

  • Patent number: 7417540
    Abstract: A wireless detector and alarm system, such as for example a smoke detector and/or carbon monoxide (CO) detector, operable to be linked and unlinked with one or more like detectors thereby forming a network of detectors. A detector sensing the presence of an environmental condition, which requires the sounding of an alert is operable to transmit a signal to other remotely linked detectors, thereby triggering the remotely linked detectors to sound an appropriate alarm. The detector at the location of the environmental condition causing the alarm and the remotely linked detector are capable to operate in teach and learn modes such that the address or “house codes” of the detectors can be synchronized.
