Title: Method and system for intercepting application program interface
Inventor: HOLLANDER YONA
IPC: G06F11/30
Filed: 2002-05-13
Abstract: A method of intercepting application program interface, including dynamic installation of associated software, within the user portion of an operating system. An API interception control server in conjunction with a system call interception module loads into all active process spaces an API interception module. An initializer module within the API interception module hooks and patches all API modules in the active process address space. When called by the application programs, the API routines' flow of execution, by virtue of their patched code, is re-directed into a user-supplied code in a pre-entry routine of the API interception module. The API- routine might be completely by-passed or its input parameters might be filtered and changed by the user code. During the operation, the API routine is double-patched by the API interception module to ensure that all simultaneous calls to the API routine will re-direct its flow of control into the API interception module. A user-supplied code in a post-entry module of the API interception module might filter or change the return values of the API.

Patent CA-2391339-A1 (CA)
Title: Emat transmit/receive switch
Inventor: MACLAUCHLAN DANIEL T
IPC: G01N29/36
Filed: 2000-08-15
Abstract: A transmitting and receiving switch assembly for an electromagnetic acoustic transducer (EMAT) and a method for selectively switching an EMAT between transmit mode and receive mode both use a particular circuit. This circuit contains an EMAT coil (20) coupled to a tuning capacitor (10), which allows the EMAT to be operated at a desired frequency when transmitting. A set of capacitors (40, 42) separates the EMAT coil (20) from a set of diode strings (70, 72) (preferably containing at least one fast switching diode), which are joined by a resistive connection (61, 62, 63, 64). A transformer (50), which is center tapped at its primary winding, is coupled to the other end of the diode strings (70, 72). Finally, a receiver input (95) is connected to the transformer (50). In operation, the frequency of the EMAT (20) is set by appropriately energizing and tuning the tuning capacitor (10). A voltage is then applied in the center tapped transformer (50) and in the resistive link (61, 62, 63, 64) between the diode strings (70,, 72). The current automatically switches the conductivity of the diodes and permits the EMAT  (20) to switch modes as desired. Likewise, the method disclosed also utilizes this circuit, as described above, and involves several steps. First, the EMAT  frequency must be selected and set, using the tuning capacitor (10). Then, a voltage is applied within the circuit to induce transmission by the EMAT (20).  Next a sinusoidal toneburst is given within the circuit to switch the transmit/receive capabilities of the EMAT (20), and then observing the input received by the EMAT (20) - thereby permitting the alternate switching of the EMAT (20) from receive to transmit mode in a matter of nanoseconds.

IPC: B62K21/00
Filed: 2002-09-24
Abstract: This present invention relates to a Steering Apparatus for a manually operated, four wheeled, driver propelled vehicle, including a child's toy vehicle. The steering apparatus enables the vehicle to drive through turns, without a differential, by causing the vehicle to drive on three wheels while the fourth wheel is suspended above ground. The Steering Apparatus consists of a stationary steering pipe attached to the vehicle frame and a rotating steering pipe attached to the steering axel. The assembly of the Steering Apparatus causes the vehicle's wheel assembly (steering wheels and steering axel), to rotate on a tilted plane of rotation, not parallel to the ground, thereby causing an imbalance in the vehicle weight distribution among the wheels. Heavier weight construction in the steering end of the vehicle mediates the tendency of the vehicle to pivot on two wheels thereby causing the vehicle's weight to be distributed over three wheels with the fourth wheel suspended above ground.

Abstract: L'invention concerne des compositions et des procédés permettant une intégration stable d'une séquence de nucléotide présentant un intérêt dans le génome d'un organisme. Les compositions sont de nouveaux vecteurs d'intégration comportant un complexe de donneur clivé actif, ou CDC, qui contient une cassette transposable Mu d'un plasmide mini-Mu ou un plasmide mini-Mu préclivé. La cassette transposable Mu comprend la séquence de nucléotide présentant un intérêt et est également liée à la transposase MuA, en vue de former le CDC. En présence d'ADN hôte lié au MuB, la protéine MuA liée comme partie du noyau tétramérique MuA facilite le transfert de la cassette transposable Mu, qui comprend la séquence de nucléotide présentant un intérêt, dans l'ADN hôte sur le site auquel le MuB est lié. La cassette transposable Mu insérée reste intégrée de manière stable à ce site, à l'intérieur du génome hôte. L'invention concerne également des procédés de transformation d'un organisme hôte au moyen d'un tel vecteur d'intégration et par un plasmide contenant la séquence codant le MuB associé de manière fonctionnelle à un promoteur qui arrête l'expression dans l'organisme hôte. L'expression transitoire de la protéine secondaire MuB a pour conséquence la liaison aléatoire de cette protéine au génome de l'organisme. L'ADN génomique lié au MuB devient le site d'insertion des vecteurs d'intégration décrits par la présente invention et de l'intégration stable de la séquence de nucléotide présentant un intérêt à l'intérieur du génome de l'organisme. L'invention concerne également des cellules, des tissus, des plants et des semences de plante transformée.
