Abstract: Systems, methods and computer program products are provided for distributed administration of a network environment having defined administrator authorities. A plurality of rules are defined specifying ones of a plurality of entity objects without administrator authority authorized to invoke administration powers to establish properties of target entity objects. In various embodiments, such rules are based on one or more of the properties of the target ones of the entity. An administrator application identifies one of the rules associated with one of the administration powers for one of the properties to be established and obtains a property of the target entity object designated by the identified rule to determine if the action is authorized.

Abstract: A sound transmission system comprises-a microphone, an amplifier, a low-pass filter, an ADC, a digital signal processor (DSP), a digital interface, a buffer, and a transport medium interface. The low-pass filter removes unwanted out-of-band signals, and the ADC converts the filtered analog signal to digital form. The DSP receives the digital data from the ADC and performs gain and filtering operations in the digital domain. The digital interface operates on the data and places it on the buffer where the data is stored prior to being transmitted over some channel via the transport medium interface. By powering down one or more particular components of the sound transmission system, most notably the ADC, the DSP and the digital interface, when the received signal falls below a predetermined level, power consumption is reduced.

Abstract: A communications system comprises a PDA and a Bluetooth peripheral device. The Bluetooth peripheral device is connected to the PDA by a data channel. The Bluetooth peripheral device enables the PDA to communicate with remote data networks using the Bluetooth wireless protocol. The system is configured to operate according to an algorithm that enables the Bluetooth peripheral device to enter an ultra-low power mode in which a receiver associated with data transfer can be disabled when no data is required to be transmitted. Data loss is prevented through the use of a hardware handshake mechanism that stops the PDA from sending data while the Bluetooth peripheral device is in the low power mode. Latency in the PDA responding to a change in handshake signals is provided.

Abstract: A data processing system is disclosed including a data processor for operating on data samples received from a data source, a digital to analog converter arranged to receive the data samples from the data processor and to convert the received data samples into an analog signal, and a controller arranged to monitor the magnitude of the data samples received from the data source and disable one or both of the data processor means and the digital to analog converter when the magnitude of one or more received data samples falls within a predetermined magnitude range. Such a system is able to operate in a low-power mode that may be advantageous for battery-powered device or other applications where power conservation is important.

Abstract: A server architecture remotely monitors client page render times by approximating the time lapse from when a hyperlink is first activated to request a web page to when the web page is rendered on the requesting client machine. In the described implementation, a client submits a request for a page. When the server receives the request, it locates or generates the appropriate page and attaches a script with the current time stamp. The stamped page is returned to the client and rendered. When the page is completely rendered (or some other important event occurs), the script is executed to return the time stamp to the server. The server measures the time lapse between the returned time stamp and the current time to derive a close approximation of client page render time. The server assumes that the time required to initially submit a request from the client to the server is approximately the same as the time involved in returning the time stamp.
