摘要:
A filter module (12) is proposed which includes a multiplicity of tubes arranged in side-by-side disposition to provide an annular array of flow passages (16) disposed about a common centre (17). The tubes comprise a filter material, and the disposition thereof is such as to maximize the filtration area whilst minimizing space utilization. A plurality of filter modules (12) is arranged in stacked relationship, corresponding tubes of the respective elements being in fluid flow relationship and one end of the stack being closed by a bottom plate (33). (FIGS. 1 and 2).

Methods and apparatus to determine a remainder value are disclosed. A disclosed example method involves, during a compilation phase, causing a processor to multiply a dividend value by a first value to generate a second value associated with a product. The first value is associated with a scaled approximate reciprocal of a divisor value, and the scaled approximate reciprocal of the divisor value is determined using a compound exponent value. During a runtime phase, the processor is caused to multiply a third value from the second value. The third value is generated using at least a subset bitfield of the second value. During the runtime phase, the processor is caused to determine a remainder value based on the third value. The processor is caused to store the remainder value in a memory.

Information processing methods, systems and ancillary apparatus are disclosed which are generally concerned with the principle of making use of verified information concerning a user whose identity has been verified and stored on a secure server. The server effectively provides a point of presence which third parties may make use of to send or receive information to or from or concerning a specific user reliably, whilst enabling the user to retain control over the information, typically by means of a key such as a smartcard. This may facilitate a variety of transactions over a network, such as the Internet, which would otherwise require separate verification processes to provide the same level of reliability and thereby lead to a surprising improvement in efficiency of the network.

The present invention is a method and system for providing a user with confirmation of the origin of a Web site and related information including the steps of registering a Web site with an assuring third party, saving the registration on a registration server, entering in a database the Web site's Internet domain name and cross-referencing it to the registration data, retrieving the Web site's domain with an Internet browser, and either (1) using a client application tool to call for registration data for the domain name via a secure SSL connection with the registration server, determining if the domain has been registered, and returning and displaying registration data for the domain name as a confirmed identity, or (2) calling a program on the registration server in response to an HTML tag on the domain via a secure SSL connection and passing it the domain name, determining if the domain has been registered, determining if the domain name has been registered, and returning and displaying registration data for the domain name as a confirmed identity.

The invented teaching method includes setting a token skill mastery task involving one or more repetitions of a two-handed digital maneuver by a student on a musical instrument; thereafter explaining the musical theory behind the maneuver; and associating the maneuver with a musical goal to reinforce the student's mastery of the skill. Preferably, the number of the one or more repetitions is based upon the student's level of skill mastery; the explaining includes asking the student one or more questions configured to elicit verbal responses of understanding; and the associating includes placing the skill in a musical context familiar to the student. The invented teaching system includes a skill drill tool defining a simple fingering, positioning or strumming skill to be mastered by a student; a knowledge development tool for imparting musical theory to the student that relates to a mastered skill, the knowledge development tool including a query/response protocol for posing one or more questions regarding the musical theory and for determining by answers thereto whether the student understands the musical theory; and a motivational tool for positively reinforcing the student's mastered skill by placing the mastered skill in a larger musical goal context.

A real-time path-directed controller for navigating an object along a desired path is disclosed. The controller comprises: a position sensor which contributes to the production of a conditioned object position signal to a controller summer; a heading conditioning module which contributes to the production of a conditioned heading signal to the controller summer; a control apparatus sensor which contributes to the production of a conditioned control apparatus signal to the controller summer; and a control apparatus null position conditioning module which contributes to the production of a conditioned null position signal to the controller summer. The controller summer sums the signals to produce a controller summer signal to a controller summer conditioning module so as to produce a control apparatus control signal to a control apparatus controller so as to direct the control apparatus and thereby direct the object by feedback control along the desired path.

An apparatus for providing weather information onboard an aircraft includes a processor unit and a graphical user interface. The processor unit processes weather information after it is received onboard the aircraft from a ground-based source, and the graphical user interface provides a graphical presentation of the weather information to a user onboard the aircraft. Preferably, the graphical user interface includes one or more user-selectable options for graphically displaying at least one of convection information, turbulence information, icing information, weather satellite information, SIGMET information, significant weather prognosis information, and winds aloft information.

Under the present invention, a customized contract is created based on the needs of the parties and is then stored within a secure computer infrastructure. Security within the computer infrastructure is typically provided through encryption such as 128 bit encryption. Moreover, all actions taken with respect to the contract (e.g., approval, execution, etc.) occur within the infrastructure and are recorded so that a record can be provided. Any party taking action will first be authenticated before access to the infrastructure is granted. In order for the contract to be electronically executed, both the originating contract partner and the receiving contract partner must first deliberately approve the contract. Once approval has been obtained, the contract can be electronically executed by both parties. After execution is complete, a final image of the contract is generated that includes the electronic signatures and the date of execution.
