Abstract: In order to provide a method of distinguishing natural from synthetic diamond which does not involve costly equipment of long periods to make a measurement, a diamond (1) is irradiated with ultraviolet radiation which is preponderantly of wavelength 225nm or less, such that substantially only the surface region of the diamond is irradiated. By observing the pattern of luminescence and/or phosphorescence produced by the diamond (1), an observer can identify the diamond (1) as a natural or synthetic diamond. In an alternative method, a diamond can be placed in an electron beam and the pattern of luminescence and/or phosphorescence produced by the diamond observed in order to determine whether there is a layer of synthetic diamond deposited upon the diamond.

Abstract: Power inverter equipment monitor/controller method and apparatus are described. The invented apparatus provides for the semi-automatic state steering and monitoring of an inverter/charger and alternator system. A flat panel user interface includes an array of switches, displays and indicators for establishing modes of operation of the system, for initializing operating parameters of the system and a connected battery, for establishing rates for the system's operation, permit the user to monitor the system's operating mode and charging data (including charging efficiency factor or CEF) while it is operating to charge the battery and to supply AC power to connected appliances. By the one of the preferred methods of the invention, tamping-up the alternator's output of current, sustaining the output until the voltage of the battery is acceptable, adjusting the output while maintaining the battery voltage at an acceptable level, reducing output until float level voltage is obtained and further adjusting output to maintain float level voltage to preserve the battery charge. By the other of the preferred methods, certain charge data related to the charging of the battery -- including a present CEF, maximum amp-hour charge level capacity of the battery (AH CL capacity), and the present status of amp-hour charge level -- are given and stored in memory, the battery is discharged, the lowest-recorded (LR) AH CL is recorded with recharge begins, completing the recharge and storing amount of amp-hours used to recharge, determining an intermediate CEF by dividing AH used-to-recharge battery by difference between the AH CL capacity and LR AH  CL, averaging the present CEF with the intermediate CEF to produce a result which is stored in memory as the present CEF, and resetting present status to the AH CL  capacity.

Title: Sensor system for controlling ventilation systems in vehicles
Inventor: RUMP HANNS
IPC: B60H3/00
Filed: 1995-04-06
Granted: 2003-07-08
Abstract: A sensor system to control the ventilation systems in vehicles in recirculation or air input mode, dependent on the concentration of pollutants in the air outside the vehicle, contains a gas sensor element (52), the electric resistance of which falls when reducing gases appear, and rises when oxidizing gases appear, and an evaluation unit (51), the output of which is connected to the controller of the ventilation unit. In order to simplify the sensor technology of such a system and in order to make evaluation less complicated, the sensor system is so organized that the increase of a gas sensor signal fed into the evaluation unit (51) for a rise in the concentration of reducing gases is the approximate quantitative equivalent of the fall of the signal fed into the evaluation unit (51) for a corresponding rise in the concentration of oxidizing gases, so that the evaluation unit (51) can measure per unit of time the rise or fall in the gas sensor signal fed in, and that the evaluation unit (51) generates a switch signal to adjust the ventilation system to recirculation mode, as soon as the measured rise or fall in the gas sensor signal per unit of time quantitatively exceeds a certain threshold limit.

Abstract: An optical proximity sensor (1) generates information indicative of a distance (DI) to an object (14A) in a field and in some embod-iments also generates information indicative of a spectral reflectance characteristics of the object (14A). The information indicative of the spectral reflectance characteristic can be used to determine whether the object (14A) in the field is a living plant (14A) or another object such as soil (10). Light emitted from the optical sensor (1) for reflection off the object (14A) is modulated so that reflected light from the optical sensor can be discriminated from reflected ambient sunlight. The opti-cal sensor (1) is scanned over the field to map objects in the field and/or to determine the location of rows of crop plants. A sensor in accor-dance with the present invention has many uses in agriculture including spraying, cultivation and vehicle guidance.

IPC: C12Q1/6825
Filed: 1995-09-20
Granted: 2009-01-27
Abstract: A waveguide binding assay method involves detecting the scattering of light directed into the waveguide, the scattering being the result of scattering labels specifically bound to the waveguide within the penetration depth of an evanescent wave. The waveguide may be transparent plastic or glass and the binding is typically by oligonucleotide hybridization or immunological capture. Light scattering labels include colloidal metals or non-metals, including gold, selenium and latex. A light absorbing member consisting of dye or concentrated particles may also be employed to enhance signal. Real-time binding and dissociation can be monitored visually or by video imaging, such as with a CCD camera and frame grabber software. Hybridization mismatches of as few as one base can be distinguished by real-time melting curves.

Title: Atm virtual path switching node
Inventor: WATANABE HIROMITSU
IPC: H04L12/70
Filed: 1997-08-18
Granted: 2001-10-02
Abstract: In an ATM virtual path switching node, upon being notified of a current virtual path by a virtual path monitoring unit, a link fault determination unit compares the number of faulty current virtual paths with a predetermined threshold value. When the number of faulty current virtual paths is equal to or larger than the threshold value, a link fault is determined, and a message communication unit transmits/receives a link fault notification signal to/from another ATM virtual path switching node. When the number of faulty current virtual paths is smaller than the threshold value, a current virtual path fault is determined, and the message communication unit transmits/receives a virtual path fault notification signal to/from another ATM virtual path switching node. The message communication unit transmits a switching control signal for designating switching from the current virtual path to a stand-by virtual path. A current virtual path information management unit manages correspondence between the current virtual path having, as one switching terminal, a self ATM virtual path switching node and a plurality of links in an ATM network.

Title: Inverter for inputting sinusoidal currents into an alternating current network
Inventor: WOBBEN ALOYS
IPC: H02M7/525
Filed: 1998-06-06
Granted: 2001-02-27
Abstract: The invention relates to an inverter for inputting sinusoidal currents into an alternating current network. The invention seeks to improve resistance to short circuiting and to reduce the risk thereof. According to the invention, only one switching unit is used to generate a semi-oscillation of a sinusoidal oscillation. In order to generate a positive semi-oscillation of a sinusoidal oscillation, a second switching unit is used in addition to the one used to generate the negative component of a sinusoidal current. As a result, only one switch pertaining to a switching unit is clocked or actuated to generate a positive semi-oscillation. Another switch is clocked or actuated to generate a negative semi-oscillation of a sinusoidal current. The risk of a short circuit between both switches is thus reduced to the period occurring between switching from the positive to the negative or from the negative to the positive semi-oscillation.
