Abstract: A network device comprising: a processor; and a memory comprising instructions which when executed by the processor cause the device to allocate a packet to a Media Session Controller (MSC) by receiving the packet; inspecting a port number in the packet header of the packet; comparing the port number with one or more MSC-port allocations in a database; selecting based on the comparison an MSC from a plurality of MSCs; and forwarding the received packet to the selected MSC.

Abstract: In one general aspect, an apparatus to monitor movement of an object may include an input device configured to trigger pre-selection of a type of performance of the object, at least one sensor used to measure a motion parameter of the object, a controller configured to receive the motion parameter of the object and compare the measured motion parameter with a motion reference, and an output device configured to display, in real-time, a feedback information based on the comparison.

Abstract: A wheel chair motor control circuit for a wheel chair having two independently controllable motor-driven wheels. The user has a "joystick" control operable from a datum position to move the wipers of two potentiometers both independently and simultaneously from their corresponding datum positions. A first, proportional control circuit is provided for each motor to supply it with drive power proportional to the magnitude of the deviation of its corresponding potentiometer wiper from datum and a second reversing circuit is provided for each motor to operate a reversing relay connected thereto in accordance to the direction of the deviation of its corresponding potentiometer wiper.
