Patent CA-2379161-A1 (CA)
Title: Wind energy facility with a closed cooling circuit
Inventor: WOBBEN ALOYS
IPC: F03D11/00
Filed: 2000-04-27
Abstract: The conversion of energy regularly results in losses in the form of heat. This applies both for the conversion of kinetic energy of wind into electrical energy in the generator of a wind energy facility, where these losses regularly occur in the main drive train of the wind energy facility, and also for the electrical feeding of energy generated by the wind energy facility into a medium voltage network. For this purpose, regular devices of power electronics, e.g., rectifiers, and/or transformers, are necessary. In the main drive train, which is mounted in the nacelle for a wind energy facility, the losses occur overwhelmingly in the gears, at the bearings, and in the generator or at other control units, such as, e.g., in the hydraulic systems or similar control and regulation units, which adjust the rotor blades or turn the wind energy facility into the wind. For gearless wind energy facilities, e.g., model E-66 of Enercon, the main losses occur at the main drive train in the generator, i.e., in the nacelle (head) of the wind energy facility.      The task of the invention is to prevent the previously mentioned disadvantages and to provide a cooling device for a wind energy facility, which reduces the losses of the wind energy facility.      Wind energy facility (1) with a completely closed or at least partially closed cooling circuit, with which the heat to be dissipated from the cooling circuit is dissipated by the tower (3) or the nacelle (2) of the wind energy facility (1).

Title: Infrared spectrometer for the measurement of isotopic ratios
Inventor: TOKHTUEV ALEXANDER
IPC: G01N21/35
Filed: 2000-07-25
Abstract: An infrared spectrometer (100) for the determination of isotopic ratios of gaseous compounds includes a broad-band infrared light source (102), a spectral selector (138), a sample compartment (106), an infrared detector (112), and a processor (114). The spectral selector (138) selectively transmits a wavelength window of infrared light covering a range of wavelengths in which the wavelength window can be selected alternatively to overlap with a wavelength range primarily absorbed by a compound with a firs t isotope or by the compound with a second isotope. The sample compartment (10 8) helds a gas sample and includes a gas inlet and a gas outlet. The infrared spectrometer (100) can be used to detect isotopic ratios of carbon dioxide, where enhancement of 13CO2 can indicate metabolic activity of an infection, for example by H. pylori, or of specific enzymes. Preferred embodiments use a particular multipass optical cell (400) that includes a field mirror (404) a nd a multi-segment objective mirror (406).

Title: System and method for intelligent trap analysis
Inventor: BIALEK ALEXANDRA G
IPC: G06F9/38
Filed: 2002-04-24
Abstract: A method and system for intelligent trap analysis for debugging software on a computer system. Instead of dumping only a register context snapshot or all of memory to a file, a trap handler determines a likely cause of a trapped instruction and selects relevant memory addresses for copying to a file. The relevant memory addresses and their contents are preserved for later analysis. The trap handler may step back through the process instruction list searching for relevant memory addresses referenced by the instructions preceding the trapped instruction. The module may undo the effect of instructions as it steps back through the instruction list.

Title: System and method for adaptive carrier occupancy in a frequency hopping spread spectrum system
Inventor: KOCKMANN JUERGEN
IPC: H04B7/26
Filed: 2001-12-05
Abstract: A frequency hopping spread spectrum telecommunication system is provided, which selects carrier frequencies based on the number of active slots. The duration that carriers have been employed is then based on the number of active slots (401, 402), rather than the number of frames (22). Thus, non-interfered with carriers can be used more often than interfered with carriers, thereby improving voice quality.
Patent CA-2405403-A1 (CA)
Title: Electronic label
Inventor: DROZ FRANCOIS
IPC: G06K19/077
Filed: 2001-04-11
Abstract: One characteristic of electronic labels in that they can be read and written  without electrical contact through the communication coil. The reading head is then positioned at some distance and interfaces with the label through magnetic waves. When said labels are placed on metallic objects, reading becomes difficult even impossible as a result of the dispersion of waves in the object. The invention proposes to avoid this inconvenience by equipping the coil with an electromagnetic element so as to insulate the coil and enhance the quality of reception.
