A method includes receiving at a receiver a voice signal in the form of a sequence of data packets, and using an automatic level control (ALC) component of the receiver to detect that one of the received packets is a silence packet or a noise packet. The method further includes receiving at a jitter delay control circuit from the ALC component a signal or signals to indicate that the one of the received packets is a silence or a noise packet, and dropping the one of the received packets in response to the signal or signals received from the ALC component. The ALC component includes a gain adjustment block and a level estimation and active voice detector block. The gain adjustment block is controlled by the level estimation and active voice detector block to adjust a gain applied by the gain adjustment block to an audio signal.

Conference calls are handled using distributed processing. In one embodiment, the invention includes receiving sets of telephone audio signals from conference subnodes, the telephone audio signals corresponding to subscribers of the conference call, selecting an output set of telephone audio signals from all of the received telephone audio signals, and transmitting the output set to the conference subnodes. In another embodiment, the invention includes receiving a set of telephone audio signals, each signal being received from a subscriber node of a single conference call, selecting a subset of the set of signals, transmitting the selected subset of signals to a conference node, receiving a second set of telephone audio signals from the conference node, and transmitting the second set to the subscriber nodes.

A method and apparatus to manage tone clamping are described.

Tone clamping and replacement

In some embodiments, a method includes detecting a tone in each data frame of a sequence of telephony signal data frames. A first data frame of the sequence of telephony signal data frames may be transmitted immediately after detecting the tone therein. Transmission of a last one or last ones of the sequence of telephony signal data frames may be deferred. It may then be determined whether the tone is present in a next data frame that immediately follows the sequence of telephony signal data frames. If it is determined that the tone is not present in the next data frame, the last one or ones of the sequence of data frames and the next data frame may be transmitted. If it is determined that the tone is present in the next data frame, a respective replacement data frame may be transmitted in place of each one of the last one or last ones of the sequence of data frames and in place of the next data frame.

A dynamic data queuing mechanism for network packets is disclosed. A three-dimensional coil may be expanded or contracted in length. In addition, the size of each loop of the three-dimensional coil may be adjusted. Moreover, simple circular queue and dynamic buffer management techniques are combined to implement circular queues that may be adjusted in size. Size adjustment, in turn, causes an entire queue either to expand or contract. Circular queue size is changed dynamically, without any copying or moving of queue data. This advantage is attained with little overhead added to conventional circular queues, and is useful in reducing memory requirements for simple circular queues by adjusting queue size as needs change. This is particularly useful for multiple queues that share the same memory space.

Dynamic data queuing mechanism for packet networks

Dynamically adjustable load-sharing circular queues are disclosed. That is, a method of reversing the processing order of a second queue placed adjacent to a first queue to allow the space allocated to both queues to be dynamically adjusted, without copying or moving queue data or affecting the performance of the input and output queue functions is described. These advantages are attained without adding any overhead to conventional circular queues, in terms of processing and memory requirements. Dynamically adjustable circular queues are particularly useful in reducing memory requirements for simple circular queues used in serving either a primary/backup or load-sharing configuration of two input queues. A simple way of determining when the queue sizes can be adjusted is further described.

A method and device for increasing the horizontal resolution of both a color flat panel display and a cathode ray tube (CRT) display. The method involves fine horizontal positioning of pixels according to information encoded in the color. Since pixel size is not changed, the display and processing bandwidth requirement is not increased. For the case of the color flat panel display, the fact that each pixel is constructed of a horizontal stripe of 3 primary color sub-pixels is utilized. Complex color information is spread across adjacent pixels to increase the apparent horizontal resolution by a factor of three. For the case of the CRT, a clock multiplier is used to multiply the video clock frequency by three. The apparent horizontal resolution of the CRT is increased by a factor of three by delaying pixels a varying multiple of this high clock speed. By encoding the fine repositioning information in the pixel color, the same display output can be post-processed respectively for the color flat panel and the CRT, allowing them to be driven and resolution enhanced simultaneously.

An apparatus and post-processing method for reversibly converting an existing electrocardiograph (ECG) erase bar waveform display to a scrolling waveform display. This conversion is accomplished by swapping the positions of the portions of the waveform that are displayed to the right and left of the erase bar in an erase bar waveform display each time a new heartbeat data point is displayed. The swapping function is accomplished by delaying the display of the data points to the right of the erase bar by a time period x and by delaying the display of data points to the left of the erase by x plus the amount of time required to scan an entire row. x is the amount of time required to scan all of the data points displayed to the right of the erase bar on the erase bar waveform display.
