Patent CA-2332162-A1 (CA)
Inventor: SAITO YOSHIAKI
IPC: A61N5/02
Filed: 2001-01-25
Abstract: A cancer thermotherapy apparatus of the present invention has an ortho-hexahedral cavity resonator and a loop antenna on a upper inner wall surface of the cavity resonator. The loop antenna is attached so that its loop face can be parallel to two side inner wall surfaces which are opposed each other, and orthogonal and adjacent to the upper inner wall surface. A high frequency electric power introduced into the cavity resonator is resonated in the parallel direction to the side wall surfaces on an excited mode with a constant electric field intensity along the side wall surfaces. A human body is set in the direction parallel to the side inner wall surfaces in the cavity resonator, and the resonated high frequency electric power is applied to the human body.

Title: Noise testing system with temperature responsive sensitivity
Inventor: JURANITCH JAMES C
IPC: G01J5/00
Filed: 1999-06-29
Abstract: An arrangement for isolating an energy transfer system while it is subjected to a test process for noise. The energy transfer system is of the type having an energy input and at least one energy output, and may be mechanical or electrical. The isolation arrangement has a base that supports the energy transfer system. An isolation support supporting the energy transfer system, yet affords multiple degrees of freedom with respect to the base. The energy transfer system is clamped in a manner that permits at least one degree of freedom with respect to the base, via an engagement arrangement that secures the energy transfer system to the isolation support. When mechanical or electrical energy is applied to the evergy transfer system, acoustic energy in the form of sound and/or vibration is issued by the energy transfer system under test, which acoustic energy is monitored by an acoustic sensor that issues a corresponding electrical signal. The monitored acoustic energy is responsive to a qualitative condition in the energy transfer system under test, and also to a temperature thereof. A thermal sensor monitors a temperature change in the energy transfer system under test, and the resulting temperature-responsive electrical signal is employed to control the sensitivity of the acoustic sensor. Such temperature-responsive control is effected non-linearly in certain embodiments of the invention.

Title: Method and device for semantic reconciling of complex data models
Inventor: SLUIMAN HARM
IPC: G06F17/50
Filed: 2001-04-03
Abstract: A method and device for semantically reconciling complex data models is disclosed. A first transform is initially applied to received divergent complex data models in order to extract fundamental data representing selected divergent aspects of the; complex data models that are to be reconciled. The extracted fundamental data are then semantically displayed in a manner suitable for both identifying differences between the aspects to be reconciled and for reconciling them. Input representative of a reconciliation of the fundamental data by a reconciling individual is received, and the fundamental data are reconciled accordingly to generate a single reconciled fundamental data set. The reconciled fundamental data set is then expanded into a corresponding reconciled complex data model by application of a second transform. The transforms are optionally capable of providing automatic enforcement of complex data model data abstractions and value dependencies during reconciliation.

Patent CA-2346136-A1 (CA)
Inventor: KARIMI GHARTEMANI MASOUD
IPC: H03L7/085
Filed: 2001-05-09
Abstract: A new structure for phase-locked loop (PLL) system is disclosed. As with conventional PLLs, the present invention consists of phase detection, loop filter and voltage-controlled oscillator units. An alternative phase detection structure, inspired by concepts from adaptive filtering and dynamical systems theory, is presented which substantially enhances the performance of the loop in terms of stability and dynamic performance.  Presented phase detection scheme obviates the need for sophisticated loop filters, so much so that a first order filter suffices for most applications. In addition to the normal function of a PLL, the present system directly generates estimates of the amplitude, phase and frequency of the input signal. This feature extends the range of applications of the system beyond well-known applications of PLL in various disciplines of electrical engineering.

Patent CA-2355312-A1 (CA)
Inventor: TIRLONI BARTOLOMEO ITALO
IPC: H04B10/2525
Filed: 1999-12-15
Abstract: An apparatus and method for transmitting an optical signal. The invention is directed to a transmission line having first (16) and second (18) spans of single mode fiber. The fiber of the first span has a negative dispersion with an absolute value of between about 2.5 ps/nm/km and 10 ps/nm/km at the operating wavelength. The second span (18) is connected to the first span (16) and has a positive dispersion at the operating wavelength. The positive dispersion of the second span compensates for the negative dispersion of the first span such that the cumulative dispersion across the first and second spans is approximately zero. The increased dispersion of the first span coincides with characteristics to lower non-linear effects, permits a longer length of the second span, and helps lower attenuation in the transmission line.

Title: A method for preventing repudiation of an executed transaction without a trusted third party
Inventor: CAI MING
IPC: G06Q20/00
Filed: 2000-10-02
Abstract: A protocol for prohibiting subsequent denial by one of the transacting parties of an already executed electronic transaction. This protocol enables secure Internet electronic commerce without the necessity of using a trusted third party. In this protocol, a sending party transmits to a receiving party, an encrypted first message that includes a desired product encrypted with a required key, but that does not include the required key. The receiving party uses the encrypted first message as evidence of non-repudiation of origin, i.e., evidence of non-repudiation that the sending party sent the transaction.  The receiving party transmits to the sending party a second message requesting for the required key. The sending party may use the second message as evidence of non-repudiation of receipt, i.e., evidence of non-repudiation that the receiving party received the transaction. Thereafter, the sending party publishes a third message with the encrypted required key on the sending party's web site, and the receiving party is required to go to the web site to fetch the third message. This protocol therefore ensures non-repudiation of origin and non-repudiation of receipt without a trusted third party involved in the electronic transaction.
