Title: Method and apparatus for controlling aquatic population in defined areas
Inventor: MENEZES JOHN K
IPC: A01K79/00
Filed: 1990-05-31
Abstract: ABSTRACT    A method for controlling the population of marine and aquatic species in an area of water includes the development of data concerning the response of various species to stimuli in different environmental conditions, and the generation of stimuli in the control area to affect the species in that area and thus control the population.  The stimuli are generally sonic waves, but other stimuli such as light, radio waves, and magnetism may also be employed in place thereof or in addition thereto.  The system uses a feedback monitor and computer with data concerning species response to adapt the stimuli to changing species and conditions.

Title: Optical fiber interface
Inventor: HUGHES RICHARD P
IPC: G02B6/42
Filed: 1990-08-29
Abstract: An optical fiber interface includes a detector assembly, which may include an integral fiber, for detecting an optical signal carried on a single fiber in an outbound direction and a piezo electric transducer or the like for providing relative movement between the fiber and the detector assembly to produce a modulated return optical signal in reflections of the outbound signal.  The return optical signal has a lower frequency or data rate than the outbound signal.  Several embodiments modulate the return signal by relative movement either perpendicular to or parallel to the fiber. The perpendicular movement modulates the reflected signal by varying alignment of the fiber and detector assembly, while the parallel movement modulates by varying a Fabry-Perot gap formed between the fiber and the detector assembly.  One embodiment includes a cantilever beam of semiconductor material attached to the detector surface.  The beam providing an integrated transducer and reflecting surface.

Patent CA-2027212-A1 (CA)
IPC: H04M3/56
Filed: 1990-10-10
Abstract: Abstract of the Disclosure A high-fidelity audio telephone conferencing arrangement which provides talker position information is economically provided between telephone stations over a single standard digital telephone channel. Digitized high-fidelity audio is combined with digitized phase information, derived from talker positiondetecting circuitry in a local telephone station, and transmitted over the telephone channel to one or more remote telephone stations. A receiver in each remote station decodes the digital information and provides the high-fidelity audio signal to multiple spatially separated acoustic output devices. The digitized phase information controls "panning" of the audio signal among the acoustic output devices. By varying the level of audio signal flowing to each acoustic output device, the position of the talker can be created in a specific position in the remote listener's sound field and the talker's identity thereby more easily determined. In addition, talker location information may be shared among multiple telephone stations participating in a telephone conference. Information as to the location of the talker along with the position of the talker is provided to each remotely located telephone station. The location of the talker is represented by the audio signal occurring in a designated general area of the remote listener's sound field and the position of the talker is represented by the creation of the audio signal in a specific position in this general area.
