摘要： Power over Ethernet (PoE) communication systems provide power and data communications over the same communications link, where a power source device (PSE) provides DC power (for example, 48 volts DC) to a powered device (PD). The DC power is transmitted simultaneously over the same communications medium with the high speed data from one node to the other node. The PSE typically includes a controller that controls the DC power provided to the PD at the second node of the communications link. The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. The PSE controller includes a resistorless switch to measure the current. The resistorless switch includes a sense transistor and a current mirror to allowing the PSE controller to calculate the current based upon a replica current.

摘要： A system and method for implementing fairness in the powering of computing devices in a power over Ethernet (PoE) application. Power supplies in a power sourcing equipment are often oversubscribed. This oversubscription can lead to starvation of certain computing devices that have power requests that are not granted relative to competing requests. A fairness consideration can be implemented to ensure that starvation conditions are avoided.

摘要： A method of initializing system components of a wireless-controlled lighting system. The system components include a remote control and a plurality of lighting units which communicate with a control master for the system via commonly-received radio communications. In order to become part of the system, each component transmits a respective request for initialization. A local control master for the system responds to each request, in turn, by allocating and transmitting a unique ID code for the requesting component. It then transmits a verify command to the requesting component which, if it has received the ID code, signals the user affirmatively.

摘要： Disclosed are a system and method of selectively awaking processes in response to an interrupt condition. A processing system may host a plurality of processes where each process is associated with an event causing an interrupt condition at a device. When a process transitions to a sleeping state, an identifier of the process may be associated with an address in a data structure. In response to an event at the device causing an interrupt condition, an interrupt service routine may associate data received from the device with the identifier in the data structure to locate the sleeping process. The located process may then be awakened while maintaining other sleeping processes associated with other events in a sleeping state.

摘要： An apparatus and method for multi-point detection in a power source equipment (PSE) device is provided. During multi-point detection, a series of at least four currents is sequentially applied to a link port of the PSE device. Each current is applied during a different measurement interval. A voltage measurement sample is obtained for each of the measurement intervals. A difference in voltage between alternating voltage samples is determined and used by a detection module to determine whether a valid power device is coupled to the link port of the PSE.

The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. In addition, the PSE controller may detect and validate a compatible PD, determine a power classification signature for the validated PD, supply power to the PD, monitor the power, and reduce or remove the power from the PD when the power is no longer requested or required. The PSE controller also monitors for a Maintain Power Signature (MPS). The PSE controller removes power from the PD if the MPS condition is absent for longer than its related time limit. The MPS consists of two components: an AC MPS component and a DC MPS component. The PSE controller may optionally monitor the AC MPS component only, the DC MPS component only or both the AC and the DC MPS components.

During detection, if the PSE finds the PD to be non-compatible, the PSE can prevent the application of power to that PD device, protecting the PD from possible damage.

摘要： A balanced approach is provided for interrupt coalescing, wherein interrupts of locking and other small size packets are maximized, while large data segment interrupts are minimized. Thus, the most desirable interrupt characteristics of both large data segments and smaller packets are achieved. Usefully, a data processing system has an adapter connecting the system to a network to receive incoming packets of varying size, the incoming packets respectively carrying messages to interrupt the system processor. Each incoming packet is analyzed, to determine whether or not it meets one or more prespecified criteria, at least a first criterion being related to the size of the incoming packet. The processor is immediately interrupted in accordance with the interrupt message carried by the analyzed packet, if the packet meets all the prespecified criteria. If the analyzed packet does not meet all of the prespecified criteria, the processor is interrupted in accordance with a specified interrupt coalescing technique.
