Abstract: An improved system and method for defining an event based upon an object location and a user-defined zone and managing the conveyance of object location event information among computing devices where object location events are defined in terms of a condition based upon a relationship between user-defined zone information and object location information. One or more location information sources are associated with an object to provide the object location information. One or more user-defined zones are defined on a map and one or more object location events are defined. The occurrence of an object location event produces object location event information that is conveyed to users based on user identification codes. Accessibility to object location information, zone information, and object location event information is based upon an object location information access code, a zone information access code, and an object location event information access code, respectively.

Abstract: A method for specifying pulse characteristics applies codes having pre-defined characteristics to a layout. The layout can be sequentially subdivided into at least first and second components that have the same or different sizes. The method applies a first code having first pre-defined properties to the first component and a second code having second pre-defined properties to the second component. The pre-defined properties may relate to the auto-correlation property, the cross-correlation property, and spectral properties, as examples. The codes can be used to specify subcomponents within a frame, and characteristic values (range-based, or discrete) within the subcomponents.

Abstract: This invention is a computer based system for the assessment, management and instruction of students, and for the delivery of work pages and other instructional materials in the form of electronic student workbooks. The computer based assessment of the student produces a student profile including skill gaps or learning objectives. Teacher (20) and student (22) workstations are networked CPUs with pen-based tablet inputs, and displays network with a central processor (10) and data base. A director workstation may also be networked with the central processor. The central processor generates a teacher workbook either directly or with input from the director workstation. The teacher, or teacher and director together, assemble an electronic student workbook containing instructional materials correlated with the student profile. The system tracks useful data such as instructional material (e.g., textbook pages, work sheets, software, simulations, tests, etc.) delivered to students.

Abstract: In a computer system that contains an input output (I/O) bus connecting to I/O devices, a central processing unit (CPU), a CPU cache memory, a system memory not directly accessible via the I/O bus, and a system bus used for conducting data transfers between the I/O bus and both the CPU cache and system memory, a method and apparatus are provided to allow addressable memory locations in both the system memory and I/O devices coupled to the I/O bus to be cacheable in the CPU cache. The I/O bus supports data transfers between pairs of I/O devices, as well as data transfers between individual I/O devices and the system which presents a problem of maintaining coherency in the CPU cache when data is written by one I/O device to a cacheable memory location in another I/O device.
