Publication number: 20040174266Abstract: A fish farming net having conductive wires integrated into the filaments of the net. The conductive wires are arranged in circuits, each of said circuits defining a field connected to an electronic apparatus that monitors a certain electrical parameter of the field. The wires of each circuit are arranged in a pattern whereby the wires are close enough together that a hole large enough for fish to escape will necessarily break one of the wires. In the event the circuit is broken, the monitoring apparatus detects a change in the electrical parameter being monitored and signals an appropriate alarm.Type: ApplicationFiled: December 17, 2003Publication date: September 9, 2004Inventor: Leif Erik Larsen

Publication number: 20040158458Abstract: Described is a transmission system (20) comprising a transmitter (22) for transmitting a narrowband speech signal, e.g. bandwidth limited between 300 and 3400 Hz, to a receiver (24) via a transmission channel (26). The transmission system (20) is characterized in that the transmitter (22) or the receiver (24) comprise amplifying means (28,30,32,34,36,38) for enhancing a listener's perception of low-frequency speech signal components by amplifying a frequency band of the narrowband speech signal. The frequency band may contain frequencies in the range of 300-450 Hz. The amplifying means (28,30,32,34,36,38) may comprise a band pass filter (28,34) for deriving the frequency band from the narrowband speech signal and an amplifier (30,36) for amplifying the frequency band. The amplification of the frequency band gives a reinforced perception of frequency components below the narrowband speech signal (e.g. 50-300 Hz), compensating for the lack of the physical presence of these components.Type: ApplicationFiled: December 12, 2003Publication date: August 12, 2004Inventors: Robert Johannes Sluijter, Erik Larsen, Andreas Johannes Gerrits, Ronaldus Maria Aarts

Publication number: 20040011191Abstract: The invention relates to a method and a circuit (500) for generating a sub-harmonic of a periodic signal (100). Conventional methods of generating sub-harmonics of a periodic signal, e.g. for bass enhancement of audio signals, create considerable artefacts. This affects the timbre, the color of the audio signal. The invention presents a method of generating a sub-harmonic of a periodic signal (100) which, added to the original audio signal, produces a more natural audio signal with bass enhancement. In a first embodiment of the invention, the signal (100) is clipped at a first predetermined level (a) in every second period (116) of the signal when the amplitude of the signal is larger than a second predetermined level. In a second embodiment of the invention, the signal is clipped at a second level (a) in every first period (115) and at a third level (b) in every second period (116) of the signal, provided that the signal level exceeds a first predetermined level.Type: ApplicationFiled: September 3, 2002Publication date: January 22, 2004Inventor: Erik Larsen

Patent number: 6589102Abstract: A lens (L) with an aspheric surface (10) is held by a vacuum lens holder (12). A lap wall (42) is moved towards the lens surface (10) while in a plastic state. A polishing fabric (PF) is positioned between the lens surface (10) and the lap wall (42) before they are moved together. Fluid pressure in a chamber (44) behind the lap wall (42) is used to move the lap wall (42) and the polishing fabric (PF) against the lens surface (10). This causes the lap wall (42) to take a shape corresponding to the shape of the lens surface (10). Then, the lap wall material (42) is caused or allowed to become a solid. When the lap wall (42) is solid, the polishing fabric (PF) is caused to move relative to the lens (L) and the lap (32). The lap wall (42) holds the polishing fabric (PF) against the lens surface (10) while the polishing fabric (PF) moves across the lens surface (10) and polishes it.Type: GrantFiled: January 30, 2001Date of Patent: July 8, 2003Assignee: Larsen Equipment Design, Inc.Inventors: Colin H.

Patent number: 6575675Abstract: The invention relates to a boring tool that includes a boring bar having a center axis which at a top portion of the bar is arranged to be connected to a machine tool, and which at a bottom portion of the bar along the center axis is slit into two legs. The two legs can be movable towards or away from each other, such as by means of an adjusting screw, for exact adjustment of the position of the cutting tool with relation to the center axis. The tool is arranged in such a way that a joint through bar is detachably attached to the bottom of each of the legs of the boring bar. This joint through bar extends essentially perpendicular to the slit and center axis, and enables a cutting tool to be provided at the end of the bar. Hereby an especially simple tool is obtained which can be adjusted extremely precisely for fine machining of holes.Type: GrantFiled: November 8, 2001Date of Patent: June 10, 2003Assignee: Larsen Tooling ApSInventor: Erik Larsen

Patent number: 5593340Abstract: A single castable ophthalmic lens polishing lap includes a mounting plate that is adapted for connection to a lap press/cylinder machine and includes a flexible membrane that is affixed to the mounting plate and filled with castable material. A polishing pad is affixed to the flexible membrane. The lap is cast by first applying energy to the castable material that causes it to soften, and to preferably change to a fluid phase, and then pressing the lap against the rough cut back surface of a lens. This causes the castable material to deform so that the lap's curvature is complementary to the lens' prescription curvature. Energy is then removed from the lap so that the castable material solidifies in the desired shape. After polishing, the lap can be recast with another lens having a different prescription.Type: GrantFiled: September 28, 1995Date of Patent: January 14, 1997Assignee: DAC Vision, Inc.Inventors: Thomas E. Nelson, Erik A. Larsen
