摘要： A ringtrip detector comprises a reference counter for controlling a battery current generator, which shapes the ring signal, a zero pass detector for detecting zero passes in a voltage at a node, which is proportional to the telephone line current and two other counters. The zero passes of the voltage create a pulse at both the positive and the negative zero crossing of the zero pass detector. The reference counter is gated into a memory, when these pulses appear. The zero passing of the previous and the present ring cycle are stored in the memory. A counter decides the difference between the previous and the present ring cycles zero passes. If the zero pass difference between the present and previous ring cycles is greater than a fixed value, the output will indicate a "phase difference" and if it is less than the fixed value it will indicate "no phase difference". Another counter counts a predetermined number of successive ring cycles with "no phase difference" at the start of a ring burst signal, and after establishing the ring burst signal, another predetermined number of successive ring cycles with "phase difference" is counted to detect the ringtrip.

摘要： A telephone circuit, which may be monolithically integrated, for supplying ringing signals to a subscriber's line and for detecting an off the hook condition during ringing includes a circuit for supplying ringing signals coupled to exchange control components for generating a constant frequency sinusoidal signal which gives rise to the ringing signals and an enabling circuit, controlled by the exchange components, for enabling the supplying of the ringing signals to the line and for activating a circuit for detecting a direct current on the line. The circuit for detecting a direct current on the line supplies a signal to a circuit for controlling the detection of an off the hook condition, and which supplies an inhibiting signal for the enabling circuit and check, only after a predetermined time, whether the circuit for detecting a direct current on the line is still supplying a signal and for generating a signal informing the exchange components that the set has been off the hook. The circuit also includes a circuit which amplifies the ringing signals and simultaneously supplies the telephone line. A circuit for generating timing signals synchronizes the operation of the enabling circuit and the circuit which controls the detection of the off the hook condition, and also the supplying of ringing signals to the line, during the times in which the sinusoidal signal generated by the exchange control components has a zero amplitude.

摘要： The method includes generating a binary signal (S4A to S4D) which is time modulated. To do this, an alternating signal (S1) is compared with a known cyclical signal (S5) and a threshold signal. There is measured the durations between the transitions of the modulated signal by means of a high speed clock and by means of counting in the positive and negative directions of the clock pulses for one or more periods of the signal under examination. If, after counting, a residual value is found, one generates a binary signal representing the transition.

摘要： Ring trip is detected when a telephone set which is being rung goes off-hook, through the use of a comparator in which the ringing signal superimposed on battery feed voltage is compared with a fixed reference voltage closer to ground than the battery feed voltage. Inasmuch as the duty cycle of the ringing signal with respect to the reference voltage is less than or equal to 50% under pre-trip (on-hook) conditions and will increase under trip (off-hook) conditions, the comparator output is a square wave form of corresponding duty cycle. An up-down counter is caused to count up when the comparator output wave form is of one level and down when the comparator output wave form is of another level during each cycle of the ringing signal. The counter counts up during the portion of the comparator wave form which determines the duty cycle and down during the rest of the period of the cycle. Underflow and lack of underflow states of the counter respectively indicate nonring trip and ring trip conditions. Logic responsive to these conditions causes deactuation of a ringing relay to enable disconnection of the ringing signal from the ring lead going from the line circuit to the telephone set. The line circuit has a calling bridge which provides an output which is used to prevent the ringing relay from reoperating unless the telephone set remains on-hook after ring trip detection.
摘要翻译：通过使用将电池馈电电压叠加的振铃信号与比电池供电电压更接近的固定参考电压进行比较，使用比较器检测正在梯级的电话机摘机时的环路跳闸。由于在跳闸（挂机）条件下振铃信号相对于参考电压的占空比小于或等于50％，并且在跳闸（摘机）条件下将增加，所以比较器输出为方波形式相应的占空比。当比较器输出波形在振铃信号的每个周期期间比较器输出波形为另一个电平时，当比较器输出波形为一个电平和下降时，引起递减计数器的计数。在比较器波形的部分期间，计数器向上计数，该周期的剩余时间期间确定占空比和下降。计数器下溢和欠流状态分别表示非跳闸和环路跳闸情况。响应于这些条件的逻辑导致振铃继电器的停用，以使得振铃信号能够与从线路电路到电话机的环形引线断开。线路电路具有一个呼叫桥，提供一个输出，用于防止振铃继电器重新操作，除非电话机在环路跳闸检测后保持挂机。

摘要： A telephone line interface which performs the BORSHT functions employs pulse width modulation and eliminates dc in the transformer to reduce the size of the coupling transformer thereby reducing space and costs. The ring function is provided to the subscriber without use of mechanical relays. An automatic, dynamically adjusted hybrid network is provided for removing echo signals thereby providing major improvement in two-to-four wire conversion performance. The circuitry lends itself to large scale integration thereby reducing space and cost and improving reliability.

摘要： The duty cycle of an AC telephone off-hook signal is measured by means of comparing it with the duty cycle of a known AC signal having a duty cycle of 0.5 because it has a DC component of zero. Measurement of the duty cycle in a telephone off-hook detector application involves measuring the DC portion of the signal on a pair of telephone lines from a telephone handset to an exchange. A high frequency master clock oscillator with a much higher frequency than the basic ringing voltage is used. An input signal is used to gate clock pulses to a counter when the input signal is positive. At the end of a predetermined number of clock pulses, the counter is gated into memory connected to a decoder for transmission of the decoded signal to the exchange for appropriate action.

摘要： Infrared light from an object directed into a thermal imaging television camera by a lens is passed through an angularly mounted rotating plate to impart orbital motion to the image received upon the image plane of the camera. A variable speed drive is operatively connected to the plate by an elastomeric belt to rotate the plate with a minimum of mechanical vibration. The operator can adjust the speed of the plate's rotation to improve the clarity of the particular scene being televised.
