    摘要: A portable data input or computer system includes an input/output device such as a keyboard and a display, another data input device such as an optical bar code scanner, and a data processor module. To scan bar code type indicia, the operator points the scanner at the bar code and triggers the scanner to read the indicia. All the system components are distributed on an operator's body and together form a personal area system (PAS). Components may include a scanner or imager, a wrist unit, a headpiece including an eyepiece display, speaker and a microphone. Components within a particular PAS communicate with each other over a personal area network (PAN). Individual PASs may be combined into a network of PASs called a PAS cluster. PASs in a particular PAS cluster can communicate with each other over another wireless communication channel. Individual PAS can gain access to a Local Area Network (LAN) and/or a Wide Area Network (WAN) via an access point. Individual PASs can use devices, such as servers and PCs situated either on the LAN or the WAN to retrieve and exchange information. Individual PAS components can provide automatic speech and image recognition. PAS components may also act a telephone, a pager, or any other communication device having access to a LAN or a WAN. Transmission of digitized voice and/or video data can be achieved over an Internet link.

    摘要: The waveform generator herein may be used to generate an analog waveform selected from a plurality of stored digital representations of waveforms. These are stored in a memory within a processor section of the system. At least one waveform generator section communicates with the processor section and receives parameter control words therefrom respecting the manner in which a waveform is to be generated. Each such generator section includes a function generator controller, a temporary waveform memory for storing a selected one of the waveforms and a digital-to-analog converter. After receiving the parameter control words from the processor section, the function generator controller operates independently of the processor section for reading the data words stored in the temporary memory and generating the selected analog waveform.
