Patent CA-2363383-A1 (CA)
Title: Photodynamic stimulation device and methods
Inventor: LARSEN ERIC
IPC: A61N5/06
Filed: 2001-11-15
Abstract: A treatment device which uses cold red and infrared radiation for the photodynamic stimulation of cells, especially cells of human tissue. The described device produces a constant energy radiation by the use of semiconductor and or laser diodes, which furthermore radiate light in several separate wavelengths due to a special operation mode. With help of sensors the advanced controller system is able to test the patients for the needed radiation doses in order to avoid over stimulation. Furthermore the radiation openings in the applicators are advantageously covered with a polarization filter, whereby the absorption in the irradiated tissue is increased. The basic equipment consists of a standpillar, with which machine applicators are connected with a jointed arm. The machine applicators are adapted for the treatment of large area tissues, for example, the back of humans. The standpillar is freely movable on wheels and includes a control mechanism, whereby the various parameters for therapy can be adjusted and switched ON and OFF. The standpillar is also connected to a hand applicator designed for the treatment of small tissue areas, e.g., acupuncture points. Another version of the hand applicator is especially devised for dental treatment, whereby the head piece of the hand applicator can be connected with an expander containing an optical fibre. Photodynamic substances are introduced into tissue to be treated, which enhances the effects of light irradiation by the inventive device. The present invention also includes a special hand applicator for introducing the light-sensitive substances into the tissue by means of air-pressure and electrical impulses (Ionto-phoresis). The advantages applied very precisely and the absorption dose can be improved and more accurately regulated without waiting time for a sufficient absorption.

Title: Blade structure in a gas turbine
Inventor: ITO EISAKU
IPC: F01D11/10
Filed: 2002-01-11
Abstract: In the blade structure in a gas turbine, inlet included angles are made large. As a result, a curve of a relative relationship between incidence angles icl and isl and pressure loss becomes mild. Entrance metal angles, which are formed by an axial direction of the gas turbine and a tangential direction to a camber line at the front edge of the stationary blade, are made small. As a result, it becomes possible to make the incidence angles small.      Chord length of a tip portion of a moving blade is made large. As a result, it becomes possible to make small the deceleration on a rear surface of the tip portion of the moving blade. Accordingly, it becomes possible to make the pressure loss small, and therefore, it becomes possible to improve the turbine efficiency.

Abstract: A spring loaded decent having a particularly designed, angled head normally utilized in holding and releasably locking two elements such as tubular members together.  The angled head assists in the of entrance of the detent into the held member and facilitates the ease of moving the detent against spring force, from its locking position for separation of the members. By increasing the ease of detent entrance into the member to be joined, a positive, yet easily releasable lock is provided between the members. Similarly, the shaping of the head of the detent reduces the pressure required to overcome the locking spring force and allows separation of the members with particular ease.

Patent CA-2386501-A1 (CA)
Inventor: NYGAARD RICHARD A JR
IPC: H04L1/24
Filed: 2002-05-14
Abstract: An eye diagram analyzer (9) equips each SUT data (19,34) and clock signal (18,25) input channel with individually variable delays (40,32) in their respective paths.  For a range of signal delay of n-many SUT clock cycles, the SUT clock signal delay might be set at about n/2. For each data channel there is specified a point in time (7) relative to an instance of the delayed clock signal (data signal delay) and a voltage threshold. The specified combination (data signal delay, threshold and which channel) is a location on an eye diagram (3,4), although the trace may or may not ever go through that location. A counter (53) counts the number of SUT clock cycles used as instances of the reference for the eye diagram, and another counter (51 ) counts the number of times the specified combination of conditions was met ("hits"). After watching a specified combination for the requisite length of time or number of events, the number of SUT clock cycles involved and the associated number of hits are stored in memory using a data structure indexed by the components of the specified combination (data signal delay, threshold). Next, a new combination of data signal delay and threshold is specified and a measurement taken and recorded in the data structure. The process is repeated until all possible combinations within a stated range (21) of data signal delay and threshold voltage (using specified resolution/step sizes for delay and voltage) have been investigated. As this process proceeds under the control of firmware (11,17) within the logic analyzer, other firmware ( 16) can be examining the data structure and generating a partial eye diagram visible on a display, and that will be complete soon after the measurement itself is finished.

Filed: 2001-02-28
Abstract: The method and apparatus enable information to be retrieved from an electronic database based on a probabilistic approach and some query processing. In one aspect, records of a database are parsed into record tokens using a pattern action language before an index for the records is created. In another aspect, a table of index tokens is created wherein the table comprises a frequency of occurrence in the database for each index token and each index token comprises a phonetic equivalent for a respective record token. In one aspect, a query is parsed into query tokens using a pattern action language, a search token is generated from a query token, and the search token is used to access database records. In another aspect, a search token comprises a phonetic equivalent for a query token or a token that qualifies as similar to a query token and search token and a search token is used to access database records. The qualification of a token as similar to a query token is based on a comparison of the query token to a database dictionary using an information theoretic algorithm. In yet another aspect, a token is selected, the selected token is used to access database records, a likelihood of relevance to the query is calculated for each of the records, and the highest likelihood of relevance to the query is compared to a continuation threshold. If the continuation threshold is exceeded, no more records are accessed and the accessed records are output. If the continuation threshold is not exceeded, the selected search token is eliminated from the set of available search tokens, and a new token is selected for accessing database records.

Abstract: Slowly rotating electrical machines, for example, ring generators, as used in wind energy plants produced by the firm Enercon of the types E-33, E-40, E-12 and E-66, require a high excitation power. The required excitation power rises with the number of poles, with increasing airgap and with the size of the reactive power. The aim of the invention is to improve the efficiency of directly-driven generators, as described above and to avoid the disadvantages described above. Said aim is achieved, whereby the generator of a slowly rotating synchronous generator (ring generator) for a wind energy plant, comprises a rotor and a stator, surrounding the rotor. The stator has at least one three-phase winding, injected with a capacitive current and/or part of the excitation power is generated by the stator.
