摘要:
A request is received from a client for a web page hosted by a web server. Responsive to this request, a persistent client state object having an identifier therein is returned to the client. When a request is received from a client for elements of the web page hosted by the web server, the client is first required to return the persistent client state object having the identifier therein before the requested web page element is sent to the client.

A process is provided for operating a computer system (100) having a storage holding an operating system (OS) and an application program (APP.exe) and a third program (VSP Kernel), a first processor (106) having an instruction set, and a second processor (1730) having a different instruction set. The process includes a first step of running the first processor (106) to determine whether a part of the application shall be run on the first processor or the second processor and then establishing a second processor object (VSP OBJECT1) if said part shall be run on the second processor and the first processor (106) sending a message that the second processor (1730) is to run said at least part of the application program. The third program establishes message handling functions and bus masters data transfer operations for the second processor between the host running the operating system and the second processor running the third program. The process concurrently runs the second processor to perform operations defined by the third program, including to access memory to detect the message that the second processor is to run said at least part of the application program, and runs the second processor (1730) to access the second processor object and thereby determine operations for the second processor to access second processor instructions for said part of the application program and data to be processed according to said second processor instructions.

An integrated circuit (1720) includes a dual-port memory (3330.1) having a first memory port (Port A) and a second memory port (Port B), a bus interface block (5010) including bus master (5016) and bus slave circuitry (5018), and a byte-channeling block (5310) coupled between the first memory port (Port A) and the bus interface block (5010) operable to convert non-aligned data addresses into aligned data. Advantageously, this invention includes a single bus master serving all application hardware. This relieves the host of the extra burden of communicating to slave circuits, reducing host I/O MIPS significantly. The digital signal processor with an ASIC wrapper of this invention together provide super-bus-mastering to access the entire memory space in the system, including the entire virtual memory space accessible by the host processor. Other processes, systems, devices and methods are also disclosed.

摘要:
An orthopedic device delivers dynamic forces to a desired remote bone region. Dynamically arranged mechanical forces are known to stimulate bone cells (the process of mechanotransduction). The device includes an implantable element configured to couple with a generally accessible and healthy bone area, from which location it's configured to transmit forces to a remote bone area in need of repair, regrowth, or regeneration. Further, the device positions and orients the implantable element where it can be readily acted on by the device's force generator. The force generator is configured to impart dynamic forces that are transmitted through the implantable element and into a desired bone mass including a remote bone area in need of repair. This device promotes fracture healing, treats osteoporotic or other poor quality bone, and promotes vertebral fusion in conjunction with a spinal fusion procedure.
