Abstract: A monitoring device, including an encasement having an upper part and a lower part; wherein the lower part is attached by a hinge at a first side of the encasement to the upper part; wherein at an opposite side the upper part can be lowered onto the lower part to close the encasement or lifted up to open the encasement; an elongated strap with a first end and a second end wherein the first end of the strap is attached to the first side of the encasement and configured to enable coupling the monitoring device to a person by wrapping the strap around a limb of a person, and inserting the second end of the strap into the opposite side of the encasement onto the lower part and covering it with the upper part.

Abstract: A matrix card is provided. The matrix card includes a plurality of physical layer devices. Each of the physical layer devices is adapted to support cells of first and second priorities and including a controllable port. The ports are in operative communication with each other to provide for the transmission of all cells of the first priority from all of the plurality of physical layer devices before transmitting any cells of the second priority from all of the plurality of physical layer devices.

Abstract: An ATM buffer system includes a buffer to communicate with 16 ATM ports, and the system can implement two buffers to communicate over 32 ATM ports. A flow control signal is provided between the buffers in the 32-port configuration to route a buffer status signal to an ATM matrix using overhead data. The multiple buffers communicate with the ATM matrix using a single low voltage differential signal (LVDS) transmit and receive connection.
