摘要： A digital burst mode communication system operates at a fixed wavelength for transmission and reception of burst mode signals using a pair of transceivers and a single optical cable. The stray noise level in the system is significantly reduced by use of angled plate absorbers that receive scattered transmission burst signal from a 45 degree partially reflecting mirror. Isolation of received burst signal from transmitted burst signal is increased to better than 30 dB. The system operates by sending only data bits across the single optical cable without scrambling or encoding preambles, significantly improving the efficiency of high speed communication.

摘要： A clock and data recovery circuit and method are used in a digital data communications system. The circuit and method are effectively employed for high speed, burst-mode transmission and allow rapid recovery of the clock and data signals without the need for an extended header, and notwithstanding the presence of substantial timing jitter. The method adaptively selects from among three delay times for the extraction of data by identifying a frequently recurring incoming pattern in the incoming data. The delay time is selected in a manner that insures that the same pattern is present in the reconstructed, resynchronized output data.

摘要： An electronic apparatus which detects when a battery having a different characteristic is mixed in a plurality of batteries accommodated therein. An average voltage V1 per battery of plural batteries connected in series and an average voltage V2 per battery at a connecting point halfway of those connected batteries are detected. A difference in voltage |V1−V2| between the average voltage V1 and average voltage V2 is compared with a tolerable voltage difference ΔV. If it is determined that a battery having a different characteristic is mixed, the operation of the apparatus is interrupted and an alarm is displayed or the supply of power is shut down.

摘要： Power control for a laser used for bust mode communication as well as end-of-life detection for the laser are performed in a combined manner, resulting in a savings in both cost and power consumption. This is achieved by employing a peak comparator which is supplied with an indication of the magnitude of a the laser signal, and supplying to the peak comparator in a time multiplexed manner with different thresholds, such as a first threshold which is used for performing power control and a second threshold which is used for performing end of life detection, on an alternative packet-by-packet basis. Thus, the first threshold is supplied for the duration of a first packet and the second threshold is used for the duration of a second packet. Additional thresholds and packets may be employed for other functions as desired by an implementor.
