A signal distribution system for distributing signals, such as for outdoor wireless networks, comprises a number of remote hubs, each of which can direct wireless signals to a number of antennas. The antennas are used to provide wireless service to the service users, such as mobile units, within their geographic coverage area. The remote hubs are connected to main hubs, which are usually located centrally. Each main hub can support a number of remote hubs. The main hubs are connected to a number of base stations (again usually located centrally) in a flexible and re-configurable manner using a switch matrix. Some remote hubs may also include switched matrices for a further level of signal routing.

Method and device for therapeutic or aesthetic treatment of the skin performs a combination of dermabrasion to mechanically modify at least an outer layer of the skin in a first region and phototherapy. The device preferably employs a skin interface element with projections protruding from a substrate which is moved in a vibratory motion by a vibration generating mechanism. This is combined with an illumination system deployed to direct a therapeutically relevant dosage of light towards a surface of the skin against which the skin interface unit is in contact.

A packet network congestion control system using a biased packet discard policy includes a plurality of end points having codecs operating in a framework, e.g. ITU-T H.323 protocol to establish a communication session. The protocol enables the codecs to negotiate codec type and associated parameters. Once a connection and session are established, compressed voice and data packets start flowing between the two end points. A control entity supplies congestion control packets periodically. The control packets provide a “heartbeat” signal to the codec at the other end of the session. Each codec receiver uses the “heartbeat” signal as an indication of network congestion. As network congestion increases, routers within the network discard excess packets to prevent network failure. The network discards all packets classified as congestion control packets whenever a flow control mechanism detects congestion or a trend toward congestion. As packets are discarded, the end points renegotiate codec type and / or parameters to realize lower bit rates.

An offload system, method, and computer program product are provided. In use, data is communicated between a host and at least one network utilizing a network interface capable of transport layer processing. Further, a port associated with the data is identified. The connection, by which the data is communicated, is managed utilizing the network interface. Further, the connection and the port are bound.

In one embodiment, a transmitter assembly containing a light source is electrically powered. The light source receives electrical power and converts the electrical power to an optical power beam that is directed through free space to an optical-to-elect power converter for a device. The optical-to-electric power converter converts the optical power beam to electrical form, thus providing electrical power to a device. A safety subsystem assures that the emission beyond the hot zone between the transmitter and receiver do not exceed regulatory levels.

A network system for actively controlling congestion to optimize throughput is provided. The network system includes a sending host which is configured to send packet traffic at a set rate. The network system also includes a sending switch for receiving the packet traffic. The sending switch includes an input buffer for receiving the packet traffic at the set rate where the input buffer is actively monitored to ascertain a capacity level. The sending switch also includes code for setting a probability factor that is correlated to the capacity level where the probability factor increases as the capacity level increases and decreases as the capacity level decreases. The sending switch also has code for randomly generating a value where the value is indicative of whether packets being sent by the sending switch are to be marked with a congestion indicator. The sending switch also includes transmit code that forwards the packet traffic out of the sending switch where the packet traffic includes one of marked packets and unmarked packets. The network system also has a receiving end which is the recipient of the packet traffic and also generates acknowledgment packets back to the sending host where the acknowledgment packets are marked with the congestion indicator when receiving marked packets and are not marked with the congestion indicator when receiving unmarked packets. In another example, the sending host is configured to monitor the acknowledgment packets and to adjust the set rate based on whether the acknowledgment packets are marked with the congestion indicator. In a further example, the set rate is decreased every time one of the marked packets is detected and increased when no marked packets are detected per round trip time (PRTT).
