One embodiment of an inventive networking environment includes clients called sending clients because they send network content through a network, and clients called receiving clients because they receive the network content from the sending clients through the network. Both sending clients and receiving clients are “clients” in that they rely on a management server to orchestrate the secure transfer of information from sending clients to receiving clients.

Client computers on a computer network send messages informing their management computer on the network of the status of transmissions such as those for conferences involving the client computers. Managers use the messages to maintain records of active transmissions to (1) discover transmissions that started without explicit authorization from the managers and (2) delete transmission records corresponding to transmissions that terminated without explicitly notifying the managers.

The invention relates to a method of assembling two parts of which one part is a sub-assembly formed of a plurality of relatively movable components.The method comprises the steps of holding the components of the sub-assembly in their desired relative positions for assembly, cooling the sub-assembly sufficiently to prevent relative movement between the components of the sub-assembly, and offering the sub-assembly to the other part while the components of the sub-assembly are locked against one another.It is preferred to coat the sub-assembly prior to cooling with a liquid, the cooling being sufficient to freeze the liquid to cause locking of the components.

A method for managing the delivery of power for a plurality of devices includes allocating a power limit for each of the plurality of devices and providing power to at least one of the plurality of devices. The method also includes, in response to the providing of power, measuring the amount of power utilized by each of at least one of the at least one of the plurality of devices and determining that the amount of power exceeds the power limit for the device.

According to one embodiment, a method for converting alternating current voltage signals to Ethernet in-line power includes converting an alternating current voltage signal to an approximate direct current voltage signal, adding at least one odd harmonic of the approximate direct current voltage signal to produce a compensated direct current voltage signal, and conditioning the compensated direct current voltage signal to produce an Ethernet in-line power signal.

A method for controlling multiple voltages in a power supply includes providing a plurality of DC to DC power converters. Each power converter includes a pulse width modulator controller having a control pin. The method also includes when a voltage supply to the power controllers reads a particular level. After the particular level is met, the method includes providing a respective rising ramp control signal to each respective control pin of the pulse width modulator controller such that each respective power converter generates desired voltage level over time characteristics.

An apparatus, system and method for providing variable attenuation to data signals in an xDSL frequency range are disclosed. An attenuation device has a resistive circuit coupled to a capacitive circuit that prevents telephone signals from being attenuated by the resistive circuit and allows normal operation of telephone services at a subscriber premises.

An over-voltage protection module protects communications equipment against voltage surges, including periodic voltage disturbances. The protection module provides a steady state activation voltage threshold and a reduced activation voltage threshold less than the steady state value. Upon a receiving a periodic disturbance, the module activates initially upon receiving a voltage exceeding the steady state activation voltage threshold and activates for subsequent cycles of the disturbance upon receiving a voltage exceeding the reduced activation voltage threshold.
