  • Publication number: 20060052372
    Abstract: Compounds with 5HT7 receptor affinity (some of which are novel) useful for lowering IOP, improving blood flow to the optic nerve head and the retina, providing neuroprotection, and treating retinal diseases are disclosed. The Compounds are also useful for treating sleep disorders, depression, and other psychiatric disorders, such as, schizophrenia, anxiety, obsessive compulsive disorder, circadian rhythm disorders, and centrally and peripherally mediated hypertension. Compositions and methods for their use are also disclosed.

  • Patent number: 6980484
    Abstract: An improved fish finding device and method for detecting and distinguishing marine life from a sonar reflected marker that generates artificial echoes comprises steps of 1. transmitting of sonar waves 2. receiving of sonar echoes 3. distinguishing the sonar echoes reflected from a sonar reflected marker from the marine life by the difference of frequency, intensity, waveform and duration of the echoes and converting echoes into signal using a microprocessor and 4. displaying the echoes signal of the sonar reflected marker as an icon different from that of the marine life. The relative distance of the sonar reflected marker and the marine life could also be calculated by a microprocessor. A fish nearby alarm sounds when fish swims within a preset value of distance. The improved fish finding device and the fish finding method guide the user to adjust accurately the bait next to fish.

  • Patent number: 6934218
    Abstract: A sounding device for showing its location on a sonar fish detector including a sonar wave receiving unit (10) to detect the sonar signal, a sonar wave producing unit (20) to simulate the reflection of the sonar wave from the fish, a control unit (30) to regulate the function of the wave receiving and producing units through on-off switches (12) and (22), and a power supply (40) to provide the electricity for the sounding device. The control unit may also receive command remotely from a sonar fish detector or a remote controller to turn on/off the sounding device as well as to perform other functions.
