Title: Architecture for an extensible real-time collaboration system
Inventor: POTRA ADRIAN
IPC: G06F9/54
Filed: 2004-10-22
Granted: 2012-06-26
Abstract: An architecture for an extensible real-time collaboration system is provided. The architecture presents a unified application program interface for writing application programs that use communications protocols. The architecture has activity objects, endpoint objects, and multiple media stacks. These objects may use various communications protocols, such as Session Initiation Protocol or Real-Time Transport Protocol to send and receive messages. The activity objects, endpoint objects, and multiple media stacks may each have one or more APIs that an application developer can use to access or provide collaboration-related functionality. These objects map the API to the underlying implementation provided by other objects. Using the activity objects enables a developer to provide less application logic than would otherwise be necessary to provide complex collaboration services.

Abstract: A method and apparatus for improving the fault protection of a monitor circuit is provided by coupling an input protection circuit to an output section. The input protection circuit may include a fusible device that limits or removes a fault condition present at an input to the input protection circuit. The fusible device may be, for example, a resettable positive temperature coefficient ("PTC") device configured to limit the current passing through it to a predetermined level once it reaches a predetermined temperature. A  resistive element may be thermally coupled to the PTC device to assist in reaching the predetermined temperature. The monitor circuit may further be configured to generate a sensory signal in response to a fault condition.

Abstract: A boiler firebox comprises arcuate front and rear end water walls connected respectively to front and rear ends of right and left side water walls. The end walls curve outward from respective ends of one side water wall and then inward to the respective ends of the other side water wall. The end and side water walls enclose a combustion chamber, and are connected at ends thereof such that water can circulate through the end and side water walls. Water input ports can be provided in water walls on opposite sides or ends of the firebox such that the flow of circulating water can be divided with about half entering the water wall on one side or end of the boiler and the other half entering on an opposite side or end, thereby reducing temperature variations in the water near the input ports compared to boilers with a single input port.

Abstract: This security door construction is applicable to safes, factory doors and house doors. An offset hinge assembly allows the door to swing open and closed and also to slide in and out of a door slot in the door frame at the closing edge of the door. In the construction of a safe, hooks on the inside of the door enter slots in upstands inside the safe and engage and disengage through the sliding motion. House doors and screen doors use a hinge assembly which operates in the same way as the safe. One pair of hinges are fixed to the frame and the second pair of hinges are fixed to the door. The frame and door pairs are connected by a rod or tube which ensures that the hinge axis of the door pair remains parallel to the hinge axis of the frame pair. A door locking mechanism is actuated by a conventional pneumatic door closer. A gas strut supplies the thrust to cause the mechanism to slide the door into the door slot when the door closer brings the door into register with the door slot.

Abstract: A pumping system for use in medical applications where liquids must be infused and aspirated, and which is cost effective to simply dispose of it after a single use. The system features positive displacement pump(s) (64, 80) such as reciprocating pump(s) which may contain a damping mechanism to dampen out the peaks and valleys in the fluid pressure that is pumped, which is important for preventing cavitation. Embodiments furthermore feature a shut-off valve (76) on the extraction side so that certain injected fluids such as contrast medium, are not immediately pumped out of the patient. In a preferred embodiment, the system also features means for independently controlling the fluid pressure/volume on the infusion and extraction sides, self-priming capability, a continuous fluid path, and visual air bubble detection (20), with viewports located at important points in the fluid path, such as at pumps and valves.

Abstract: A disposable wound-healing device is disclosed that incorporates a housing having a fluid-impermeable material having a cavity and a perimeter that can be sealed in an air-tight manner over a wound region of a patient. The device is capable of producing a negative pressure over the wound region by either removing oxygen from within the cavity, or absorbing fluid into the cavity and then removing the fluid from the cavity. The oxygen may be removed via chemical absorption, by an electrochemical cell or by a chemical reaction that cannibalizes oxygen from the cavity. The fluid may be removed through the use of osmotic or electro osmotic cells, or through a one-way valve. The negative partial pressure over the wound region promotes healing.
