摘要:
A method of initiating a set up process for a call between users with reduced set up times using one or more 3G telecommunication networks. The method is provided between at least a pair of H.324-like terminals coupled to the one or more 3G telecommunication networks. The method includes establishing a bearer channel between a first terminal and a second terminal after a call signaling process, transmitting a first FSS message from the first terminal to the second terminal. The first FSS message includes a first preference profile associated with a first mode of operation for the call and a second preference profile associated with a second mode of operation for the call. The method also includes selecting either the first mode of operation or the second mode of operation.

A multimedia device configured to support video in a session of a call includes one or more media providing devices and one or more computer codes directed to performing an initialization process for the one or more media providing devices. The initialization process may be performed at an initialization time prior to or substantially equal to a first time prior to or substantially equal to a reception time associated with receiving an indication of call acceptance from a called device, or second time prior to or substantially equal to an acceptance time associated with call acceptance by the multimedia device. The multimedia device also includes one or more computer codes directed to transmitting one or more preferences for the session according to a session setup procedure, one or more media processors coupled to the one or more media providing devices, and one or more computer codes directed to transmitting media on one or more media channels associated with the session.
摘要:
A method of initiating a set up process for a call between users with reduced set up times using one or more 3G telecommunication networks. The method includes establishing a bearer channel between a first terminal and a second terminal after a call signaling process and determining, at the first terminal, one or more preferences for a call between the first terminal and the second terminal. The one or more preferences are associated with one or more modes of operation for the call. The method also includes determining a mobile level for operations and interleaving the one or more preferences, the mobile level for operations, and one or more media streams. The method further includes transferring the one or more preferences, the mobile level for operations, and the one or more media streams from the first terminal to the second terminal through a portion of a telecommunication network using the bearer channel.

摘要:
A method of establishing a session between a first device and a second device. The session is established over a telecommunications network using an accelerated session setup technique. The method includes providing a first accelerated session setup technique and providing a second accelerated session setup technique. The method also includes establishing the session using either the first accelerated session setup technique or the second accelerated session setup technique based on a predetermined process.

A binary vane pump is provided. The binary vane pump includes a pressure plate having a first discharge port, a thrust plate having a second discharge port, a ring positioned axially between the pressure plate and thrust plate, the ring having an inner cam surface, and a rotor rotatably disposed within the ring, the rotor having a plurality of slots and a plurality of vanes, vanes of the plurality vanes corresponding to respective slots of the plurality of slots and radially movable with the respective slots. A first and second pump chamber are disposed within the ring, separated by the rotor, vanes, pressure plate and thrust plate, the first pump chamber configured to discharge fluid to the first discharge port and the second pump chamber configured to discharge fluid to the second discharge port. A shaft extends through the pressure plate, thrust plate, ring and rotor and drives the rotor.
摘要:
A vehicular hydraulic system with a pump and first and second hydraulic applications arranged in series. The fluid upstream of the first application may be elevated to a first threshold pressure value. A pressure-dump valve is disposed downstream of the first application and fluid entering the valve flows through an inlet port, primary flow channel and outlet port of the valve to the second hydraulic application. The valve includes a valve member that axially slides within an elongate valve chamber, partitioning the primary flow channel from a low pressure volume. The valve also includes a low pressure port and a bypass port that diverts fluid past the second application. The valve member is biased into a position wherein fluid is diverted through the bypass port when the pressure in the primary flow channel exceeds a second threshold value. The first threshold value is greater than the second threshold value.

A vehicular hydraulic system having a hydraulic pump and first and second hydraulic applications arranged in series. A dual relief valve defines first and second flow channels, a passageway and a bypass port. The first flow channel is disposed between the hydraulic pump and the first hydraulic application and the second flow channel is disposed between the first hydraulic application and the second hydraulic application. A first valve member controls fluid flow through the passageway and allows fluid flow from the first to the second flow channel through the passageway when fluid pressure within the first flow channel exceeds a first threshold pressure. A second valve member controls fluid flow through the bypass port and allows fluid flow from the second flow channel to a return line through the bypass port when fluid pressure within the second flow channel exceeds a second threshold pressure.

A binary vane pump providing a balanced, stepwise variable displacement is provided. The binary vane pump includes a pressure plate having first and second discharge ports configured to discharge fluid from the binary vane pump to a first discharge path and a thrust plate having third and fourth discharge ports configured to discharge fluid from the binary vane pump to a second discharge path. The binary vane pump also includes a ring positioned axially between the pressure plate and thrust plate, the ring having an inner cam surface, a rotor rotatably disposed within the ring, the rotor having a plurality of slots and a plurality of vanes received and movable within respective slots, and a shaft extending along an axis through the rotor and configured to rotate the rotor so that the vanes are rotatable within the ring.

A hydraulic fluid reservoir assembly is disclosed. The reservoir assembly includes a reservoir housing defining a fluid chamber and a baffle member. The baffle member is disposed within the fluid chamber above the inlet and defines a central opening disposed radially inwardly of the reservoir housing. The central opening provides fluid communication between an inlet zone below the baffle and an upper zone above the baffle. The hydraulic fluid introduced through the inlet is directed to flow circumferentially along a radially outer section of the inlet zone whereby air entrained in the hydraulic fluid collects in a central portion of the inlet zone and is communicated to the upper zone thereby deaerating the fluid. A means for forming a substantially fluid tight seal between the reservoir housing and the baffle member is provided along an outer radial edge of the baffle member. A method of manufacture is also disclosed.
