International Classification:

G06F 1328

US Classification:

Abstract:

An apparatus and method for transferring high speed asynchronous data using a DMA controller. By using a conventional Universal Serial Asynchronous Receiver Transmitter (USART) with a small buffer, high speed asynchronous data can be manipulated by the DMA controller by use by other applications, such as wireless communication applications. The wireless communication applications includes Global System for Mobile communications (GSM), Code Division Multiple Access (CDMA), or Personal Digital Cellular (PDC). These wireless communication applications utilize high asynchronous data rates that would require more expensive USART with additional buffer capacity. In the receive mode, the high speed asynchronous data shifted into a DMA FIFO buffer from the USART. The data is then flushed into a host memory, such as a protocol stack by the DMA controller once the FIFO is full or if a timer expires. The data in the protocol stack is then manipulated by the wireless communication application.

US Classification:

375268000, 375300000, 326082000

Abstract:

According to one embodiment, an isolation barrier comprises a transformer and a controlled impedance module. The system side device generates an amplitude modulated clock signal when the system side device is in a transmit mode, and generates an unmodulated clock signal when the system side device is in a receive mode. When the system side device is in the receive mode, the controlled impedance module modulates, according to the data being transmitted by the line side device, the unmodulated clock signal incoming from the system side device. The transformer is utilized in bidirectional data transfer to provide the line side device with the amplitude modulated clock signal generated by the system side device, while providing the system side device with the amplitude modulated clock signal generated by the controlled impedance module and the line side device.

US Classification:

434118

Abstract:

A freestanding visual aid is disclosed which includes instructional material displayed on multiple sufaces of a geometric object to allow the selective display of indicia representing information, on at least one of the surfaces, in a resting position of the geometric object. The indicia displayed by each face of the freestanding object is preferably related to one of a plurality of modes of operation of an apparatus or system with which the visual aid is used. Each surface, for example, may include an explanation of the key functions and command language applicable to a different computer program when the visual aid is used in connection with the operation of a computer or microprocessor system. The freestanding object allows immediate selection of the appropriate instructional information represented by the indicia on a given surface for the particular program employed by the computing system.
