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： An optical network unit is associated with a multi-wavelength optical fiber communications system carrying low-power digital signals bidirectionally transmitted at a first and a second wavelength and a high-power analog video signal transmitted at a third wavelength. The unit comprises a housing having a connection for the optical fiber; and an optical filter, first and second optical units, and a beam splitter mounted in the housing. The optical filter is interposed between the fiber termination and the second optical unit, and is adapted to block light of the third wavelength but bidirectionally transmit light of the first and second wavelengths. The system is readily implemented, and any combination of the data and video services may be selected. A high level of skill is not required for changing the combination of services procured.

摘要： A burst mode digital data receiver automatically adjusts its logic reference voltage to be equal to one-half of the sum of the minimum and maximum excursions of a received data signal. The receiver includes a differential amplifier circuit which has a first input for receiving the data signal and a second input connected to a voltage reference circuit. The voltage reference circuit is responsive to an output signal from the amplifier circuit to produce the required logic reference voltage at the second input to the amplifier circuit by generating a feedback signal which causes the amplifier circuit to have a first gain value during the absence of the data signal and while the data signal is less than its peak amplitude and a second gain value approximately twice the first gain value for a predetermined time after the peak amplitude of the data signal is reached.

摘要： Disclosed is an optical package including at least one electro-optical component aligned with at least one optical fiber. The electro-optical component is mounted on a surface which is essentially parallel to, but not coplanar with, the longitudinal axis of the fiber and light is coupled between the fiber and component by bending the light path. Electrical connection to the component is provided by conductors mounted over the same surface, thus producing a compact package. The invention is used preferably with arrays of components and fibers to eliminate the need for a vertical fanout to contact the components.

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. Use of transparent glass ferrule with or without a front surface anti-reflection coating instead of an opaque ceramic ferrule to support optical fiber at a selected location within the transreceiver reduces optical detector signal noise. 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.
