Abstract: One aspect of the present application relates to a pharmaceutical composition comprising a sulfated glycosaminoglycan having an average molecular weight ranging from 3,000 to 15,000 Daltons, a skin penetrating agent, where the skin penetrating agent promotes transdermal penetration of the sulfated glycosaminoglycan when applied to intact skin surfaces, and a pharmaceutical carrier for topical application, where the pharmaceutical carrier is mixed with the sulfated glycosaminoglycan and the skin penetrating agent. This composition is useful in carrying out a method of treating a subject for pain, joint stiffness, soft tissue injury, connective tissue disorders, and/or muscle soreness.

Abstract: A virtual memory system for a computer employs decentralized management of secondary storage media. The caching of data obtained from secondary storage is controlled by software management entities that lie outside of the operating system. These entities communicate with the operating system through a message-based interface relationship. With the decentralized approach, the operating system can remain relatively simple, while specific backing store management entity modules can be tailored to accommodate new types of hardware and data organization.

Abstract: A computer has a device driver and an operating system that call a consolidated buffer service routine to coordinate the transfer of data between a main memory and an external device. The consolidated buffer service routine includes a memory preparation service routine and a memory checking service routine. The memory preparation service routine coordinates data transfers between the external device and the memory with the operating system and a data cache, and with other data transfers. The memory preparation service routine ensures that the buffer remains assigned to the memory ranges until the memory checking service routine relinquishes the buffer. Before calling the memory preparation service routine, an I/O preparation table is set which defines the addresses and the type of addresses of the buffer, the size of the data to be transferred, the page size of the buffer, and flags defining data flow and type.

Abstract: A system for custom context switching comprises a thread accounting unit, a switching routine registration unit, a thread scheduling unit, a custom context switching unit, and a default context switching unit. The thread accounting unit creates a thread object for each thread present in a multithreaded execution environment, where the thread object includes data fields for storing a unique thread ID, a reference to a custom context switching routine, and a switching parameter signal. The switching routine registration unit stores a reference to a custom context switching routine in a particular thread object. The thread scheduling unit determines when rescheduling operations for transferring execution from one thread to another are required, and directs rescheduling operations.

Abstract: A method of installing a cable, particularly but not exclusively in a duct filled with flowing liquid, wherein, as the cable is deployed, the strain in the cable is determined by sending a signal down the cable and receiving a signal back from the cable. The speed of deployment is adjusted according to the strain detected. Preferably the system is applied to optical cables, and a radio frequency signal is modulated on an optical carrier. Optical connection to the cable on the rotating drum is made via an optical slip-ring. The front end of the cable has a silvered end termination for reflecting the modulated signal back along the fibre to be detected by an optical receiver, and there is a vector voltmeter for determining the phased difference between the signals to thus determine the strain in the cable.
