International Classification:
H02M 7/537
US Classification:
363 97, 363 2113, 363 2116
Abstract:
Disclosed is a method and apparatus that includes a power supply having a primary coil and a secondary coil.

International Classification:
G08C 25/02, H04L 1/18
US Classification:
714748, 714776
Abstract:
The apparatus and method herein splits the function of a digital subscriber line (DSL) modem data pump between a digital signal processor (DSP ) and a general purpose host central processing unit (CPU ). The DSP () handles all front end data pump processing such as interface to an analog front end ( and ), FFT processing, FEQ processing, QAM decoding, and bit formatting. The host CPU () handles all back end data pump processing such as DMT tone deordering, data deinterleaving, error detection and correcting, bit descrambling, CRC processing, and the like. In order to enable the DSP () and the CPU () to communicate with each other effectively, buffers () under the control of specialized buffer management methodology (FIG. ) are used.

International Classification:
H04L 1266
US Classification:
375220
Abstract:
In a digital communication device adapted to be coupled to a digital network and having an analog port adapted for interconnecting an analog device to the digital communication device, a device for generating and detecting tones, includes: a processor programmed to selectively generate one of a first set of digital tones in a generation mode and to detect one of a second set of digital tones in a detection mode; and a conversion circuit, operably coupled to the processor, adapted to convert the one of the first set of digital tones generated by the processor in the generation mode to an analog tone and transmit the analog tone to the analog device; the conversion circuit further being adapted to convert an analog tone received from the analog device to the one of the second set of digital tones and transmit the digital tone to the processor when the processor is in the detection mode.

System For High Speed Data And Command Transfer Over An Interface Where A Non-Maskable Interrupt Signal Indicates Either A Write Command Or Received Data
US Patent:
5943505, Aug 24, 1999
Filed:
Apr 11, 1997
Appl. No.:
8/840315

Patrick J. Quirk - Huntsville AL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
G06F 1314
US Classification:
395851
Abstract:
The apparatus and method for high speed data and command transfer over an interface (202), such as an ISA or PCMCIA bus or interface, includes a transceiver (206) and a processor (210) having a direct memory access (DMA) controller (240), a memory (211) for storage of data, and a channel interface (218) for connection to a communications channel. The processor (210) is responsive through a set of program instructions, such as software or firmware, to receive an interrupt signal (310, 315) and, when the interrupt signal indicates a write command (320, 330), to transfer data via the transceiver from the interface to the memory for transmission over the communications channel (335), and when the interrupt signal indicates data received from the communications channel (350), the processor further responsive to generate a read command and transfer data from the memory to the interface via the transceiver (355).

International Classification:
H02H 7/00
US Classification:
361 18, 361 931
Abstract:
One embodiment monitors a line-side electrical current provided by a power sourcing equipment (PSE) port to a powered device (PD), the PSE port having a power-isolation transformer with a primary coil on an isolated side and a secondary coil on a line side. A switching signal having a switching period and a duty cycle is applied to the primary coil of the power-isolation transformer. A value is determined for an electrical current on the isolated side of the power-isolation transformer, conversion is performed between a line-side electrical current value Iand a corresponding isolated-side peak-current value I, and the line-side electrical current is indirectly monitored based on the determined isolated-side current value.
