摘要： An optical drive system includes a computer that monitors the current in an improved bias coil assembly in conjunction with a magnetomotive field generator to determine when a predetermined current threshold is exceeded. The bias coil assembly includes a wire coil wrapped around a center bar contained by a bias coil housing. The bias coil assembly is positionable above an information storage medium so that the entire medium may be within the magnetic field thereby allowing writing of information to all portions of the medium. When the threshold is exceeded, a sufficiently strong magnetic field is generated to permit writing of information on the storage medium utilizing a laser. A laser pulse generator is then enabled. The device thereby achieves a substantially shortened write cycle while employing the improved bias coil assembly.

摘要： An optical drive system includes a computer that monitors the current in the bias coil of a magnetomotive field generator to determine when a predetermined current threshold is exceeded. When the threshold is exceeded, a sufficiently strong magnetic field is generated to permit writing of information on a storage medium utilizing a laser. A laser pulse generator is then enabled. The system is provided with an optics module for processing light produced by the laser light source. A laser driver for energizing the laser light source is positioned in close proximity to the optics module and the laser light source to reduce noise in signals associated with the optics module. The system thereby achieves a substantially shortened write cycle while reducing relevant signal noise.

摘要： An optical drive system includes an optical assembly, a light source, a lens positioned to direct light between the optical assembly and an information storage medium or disc, and an actuator suspending the lens. A photodetector is disposed in a path of returning light to measure light received from the medium. A monitoring circuit is provided to monitor a Quad Sum signal associated with return light. A first servomotor is employed to move the lens in a tracking direction and to move the lens during focus capture while system circuitry searches for a maximum Quad Sum signal. A second servomotor is employed to move the lens in a focusing direction. A first electronic circuit is provided to control the first and second servomotors. A servo error circuit is coupled to the first electronic circuit and the photodetector to determine when return light exceeds a predetermined value, to search for a first zero crossing, and to indicate to the first electronic circuit to close focus by the second servomotor when the Quad Sum signal exceeds a predetermined amplitude. A focus capture method for use in the system includes impinging light upon the disc, moving the lens, monitoring the Quad Sum signal, moving the lens while looking for a maximum Quad Sum signal, monitoring light received from the disc, determining when the light is above a measured peak value, searching for the first zero crossing, determining when the Quad Sum signal exceeds a predetermined amplitude, and closing focus at the predetermined amplitude.

摘要： A method of testing a semiconductor memory device using a parallel march pattern method of testing. All of the memory bits in a memory device are programmed to a first logic state. All of the memory bits in selected rows are programmed to a second logic state. All of the memory bits in rows adjacent to the rows programmed to the second logic state are read to determine if the memory bits programmed to the second logic state have caused the memory bits programmed to the first logic state in the adjacent rows to change logic state. The selected rows are determined by a periodicity value that can be values such as 4, 8, or 16. The periodicity determines the number of clock cycles needed to test the entire memory device. A periodicity of 8 requires only 8 clock cycles to test the entire memory device, regardless of the size of the memory device. The parallel march pattern method of testing can be by rows, by columns or by diagonals.

摘要： A laser driver for controlling an electrical current supplied to a laser in an optical disc system. The laser driver includes pass transistors for delivering electrical current to the laser, an operational amplifier for setting a reference voltage on the bases of the pass transistors, and a CMOS buffer for applying a drive voltage to emitter circuits of the pass transistors. The drive voltage has a first voltage level and a second voltage level, and the electrical current is supplied to the emitter circuits only when the drive voltage is at the first voltage level. The laser driver further includes a switch for switching the drive voltage between the first voltage level and the second voltage level so that electrical power is consumed only when the laser is energized and enhanced rise and fall switching characteristics are thereby achieved.

摘要： A class of predominantly hydrophobic non-azo N-substituted 1,8-naphthalimide compounds, each bearing, at its 3-position, a nucleofuge and, at its 4-position, a heteroatomic electron-releasing group. The heteroatomic electron-releasing group is being characterized as having a heteroatom directly linked to the 4-position of the ring, and having at least one hydrogen directly attached to the heteroatom. Upon activation by an activating agent in an environment independent of the presence or absence of oxygen, these compounds generate activated species. The activated species initiate chemical changes in lipid bilayer membranes of viruses and other target cells. These changes can eradicate viruses and other target cells. The activated species can also cause structural changes in lipid and any associated proteins and polypeptides at a level beneath the surface of the membrane, leading to polymerization and crosslinking.

摘要： A method for the qualitative or quantitative determination of the deleterious agent in a substantially non-aqueous medium, such as an oil. The method involves using a non-azo 1,8-naphthalimide dye for the detection or quantitation of the total hydrogen ion activity in a substantially non-aqueous medium. The method includes the steps of: Mixing the dye with the substantially non-aqueous medium, which may or may not contain any hydrogen ion, to form a mixture; irradiating the mixture with a fluorescent light sufficient to cause the mixture to emit a detectable fluorescent emission spectrum; detecting the fluorescent emission spectrum of the mixture; and comparing the detected fluorescent emission spectrum with standard fluorescent emission spectra generated by reacting the dye with different known hydrogen ion activities, wherein differences between the fluorescent emission spectra compared are dependent upon the presence or levels of the hydrogen ion activity present in the mixture.

摘要： The use of a class of non-azo 1,8-naphthalimide dyes for the detection and quantitation of a paramagnetic metal cation in a non-aqueous medium and some of the dyes that will complex with a paramagnetic metal cation. The concentration of the paramagnetic metal cation is determined by monitoring differences in the detected fluorescent emission spectra of the non-azo 1,8-naphthalimide dye solution when it is mixed with paramagnetic metal cations present in the non-aqueous medium. The detected fluorescent emission spectra will vary in relation to the presence or amount of the paramagnetic metal cation in the mixture.
