Abstract: A method and system to permit the creation of “parent” accounts within a school system's data transmission system which are associated with a parent's child or children who are students in the system. A parent account is capable of creation and access by various levels within the hierarchy of the system and is associated with one or more schools within the community being serviced by the entity providing the servers and community generation implementation engine.

Abstract: The present invention is a method and apparatus for monitoring and filtering data transmission for providing the creation of a secure “virtual classroom” through which teachers can use the internet to link their students to other classes and work collaboratively and create a “shared learning” environment. A collaborative community is created by a teacher or administrator who submits initial input data to a central storage and clearing center. A first filter system is employed to ascertain and control the entrance of class data in order to ensure that the entering party is duly authorized. Once the initial input data is accepted, a search engine permits the teacher to search for compatible shared classrooms. The dynamic filtering permits security to be controlled by a central location and ties the individual classrooms into a network. The dynamic filtering level component permits each classroom and each student to be monitored to a degree designated by the teacher and appropriate for the student.

Abstract: A surgical utility tube, comprising a plurality of members, wherein the plurality of members are joined together to form a continuous first tube, wherein the first tube is bendable to a plurality of angles along a length of the first tube, and wherein the first tube locks at each of the plurality of angles, and a second tube positioned in the first tube.

Abstract: A surgical equipment supporting frame comprises a plurality of interconnected branches, an arm portion connected to at least one of the plurality of branches, wherein the arm portion extends over an operating table, and moves to different positions along the operating table, and a surgical tool connected at an end of the arm portion.

Abstract: An extramedullary fluoroscopic alignment guide is disclosed, along with a surgical method employing such an alignment guide. The extramedullary alignment guide includes both radiolucent and radiopaque material. The invention is useful in performing surgery on bones, for example, in performing surgery on the knee joint. The radiolucent material provides a support structure for the radiopaque material. The radiopaque material provides a radiopaque instrument reference that is sized, shaped and positioned so that the surgeon can simultaneously fluoroscopically view the patient's bone and the radiopaque instrument reference. The radiopaque instrument reference may be aligned with landmarks on the bone or other fluoroscopically viewable references, such as the mechanical or anatomic axis. The alignment guide can also include cutting guide surfaces.

Abstract: This disclosure provides a system for qualifying embryonic stem cells intended for human therapy. A comprehensive sequencing project has identified important markers that are characteristic of undifferentiated pluripotent cells. Combinations of these markers have been used to screen feeder cells, media additives, and culture conditions that promote rapid expansion of stem cells without differentiation. By measuring undifferentiated stem cell markers, and markers formed by early progenitors such as stromal cells, the user can quantitate the proportion and extent of differentiation. This establishes standardized criteria for master cell banks and cell cultures that can then be used to produce therapeutic cell populations and medicaments for use in regenerative medicine.

Abstract: The present invention is a method and system for monitoring and filtering of data transmission to permit the creation of a secure web-based “virtual meeting place” through which a scientist, business person, educator or other individual can use the Internet to link themselves or their group or student to others to work collaboratively and create a shared environment. A community is formed by having a person who is interested in participating in a collaborative project or just exchanging data on a given subject submit preliminary profile data to a digital storage center. The data may contain a description of the project and a general description of the of the collaboration level sought. A first filter system is employed to ascertain, verify and control the entrance of data to ensure the legitimacy of the entering party.

Abstract: The present invention is a method and apparatus for multi-level monitoring and filtering of data transmission (SchoolMail) to permit a school district or other affinity group to create a secure “virtual classroom”, “Virtual district” or “Virtual affinity group” and multiple accounts to permit a hierarchical infrastructure with varying privileges associated with each user name or category. The system provides a universal solution to allowing information flow to both students and educators, or varying participant levels within a group, while maintaining control of the type and character of material received and sent. The system can employ common service capability to permit multiple districts or user groups to have their individual SchoolMail, while at the same time providing the capability for interaction and connectivity among the districts, based upon screening and search criteria.

Abstract: The present invention is a method and system for integrating a browser into and making it a part of a monitored and filtered data transmission system for a school or other controlled environment. A browser is configured by an administrator to require that all pages be reviewed and checked before they are delivered to the recipient. The browser directs that the monitoring and filtering applicable to the hierarchical system be exercised with regard to the pages to be reviewed. The system also contains a hierarchical control level so that varying filtering and monitoring control is available at each level of the hierarchy and can be configured down to the individual user level to permit the overall system to remain secure while providing appropriate browser capabilities to the users, be they student, teachers, administrators or parents. The administrator or other control person within the hierarchy can also prevent access to any other browser, making the filtered browser the only one available to the user.
