Abstract: This communication network (18) extends between a plurality of input blocks (E1, . . . , EN1) comprising a predetermined number P1 of input ports and a plurality of output blocks (S1, . . . , SN2) comprising at least the same number P2 of output ports as the predetermined number P1. In this network, when the result of the multiplication of the number of input ports P1 by the number of input blocks N1 is even, the number N3 of switches is equal to: N ? ? 3 = N ? ? 1 × P ? ? 1 2 , and when the result of said multiplication is odd, the number N3 of switches is equal to: N ? ? 3 = N ? ? 1 × P ? ? 1 - 1 2 , and, for each switch, the first (30) and second (32) input terminals are each connected to different input blocks (E1, . . . , EN1) and the first (34) and second (36) output terminals are each connected to different output blocks (S1, . . . , SN2).

Abstract: An information handling system includes a memory and a first controller. The memory stores a mapping table. The first controller is configured to communicate with the memory. The first controller detects a presence of a second controller in response to a first node being connected to a network within the information handling system, generates a port number for the second controller, stores the port number for the second controller in the mapping table, receives an indication that an Internet Protocol address of the second controller has changed, and updates the mapping table with the changed Internet Protocol address of the second controller.

Abstract: A wireless network having an architecture that resembles a peer-to-peer network has two types of nodes, a first sender type node and a second receiver/relay type node. The network may be used in a medical instrumentation environment whereby the first type node may be wireless devices that could monitor physical parameters of a patient such as for example wireless oximeters. The second type node are mobile wireless communicators that are adapted to receive the data from the wireless devices if they are within the transmission range of the wireless devices. After an aggregation process involving the received data, each of the node communicators broadcasts or disseminates its most up to date data onto the network. Any other relay communicator node in the network that is within the broadcast range of a broadcasting communicator node would receive the up to date data.

Abstract: An electrical control system includes one or more master devices that are adapted to control the operation of one of more slave devices. The master and the slave devices are operably coupled by at least one radio frequency communication interface. The master devices are adapted to assign the slave devices to a delayed off mode of operation, define a time delay associated with each slave device, and activate the delayed off mode of operation. The slave devices include manually operated switches and are operably coupled to corresponding loads. During the delayed mode of operation, each slave device is adapted to delay a transition for the corresponding load from on to off by the time delay associated with the particular slave device.

Abstract: An electrical control system includes one or more master nodes that are adapted to control and monitor the operation of one or more slave nodes. The master nodes and the slave nodes are operably coupled by one or more communication interfaces, such as radio frequency, Internet Protocol, power line, or other conventional communication interfaces. A hand-held radio frequency controller includes a controller that is operably coupled to an radio frequency transceiver. The controller includes an operating system and application programs, including a device engine, a scenes engine, an events engine, a system engine, and an away engines. The device engine, scenes engine, events engine, system engine and away engine permit a user of the hand-held radio frequency controller to customize the operation of at least some of the aspects of the master and slave nodes.

Abstract: A data-communications switch having at least two modes of operation is provided. The data communications switch includes a first Clos switch having a first mode of operation and a second Clos switch, which is combined with the first Clos switch, for providing a second mode of operation. The first Clos switch and second Clos switch are interconnected in an overlapping manner to form a switch fabric, which is essentially a superset of both the first Clos switch and the second Clos switch and can be configured to operate in either mode depending on system requirements.
