摘要： A telephone call screener discriminates between desired and undesired incoming telephone calls. Desired calls are signaled by use of a two-digit code known only to persons selected by the user. The first digit of the code refers to the number of silence gaps between calling tones or rings that the calling party has to wait before entering a second digit of the code from one of the ten numbers on the touch tone or rotary dial on the telephone used to place the call. An incoming call is first detected and electronically answered, after which the output of a sine wave generator is periodically transmitted over the open telephone line to generate false calling tones simulating the periodic audible ringing sequence of a conventional telephone. An enabling circuit detects the correct code being signaled only during the proper silence gap in the false calling tone sequence. Either a touch tone decoder circuit or a rotary dial detector circuit is enabled to generate an output for activating a transducer, such as a bell or a light, to indicate that the desired call has been received. If the transducer is activated, the false calling tone sequence is extended to provide additional time for answering the phone, and when the extended sequence ends, the call is terminated. Even if the proper code is not detected during the correct silence gap, the false calling tone generator continues to produce false calling tones either until the calling party hangs up or until a maximum number of false calling tones is generated, after which the screener automatically terminates the cycle and resets for receiving the next incoming call.
摘要翻译：电话呼叫筛选器区分期望的和不期望的来电电话。所需的呼叫通过使用仅由用户选择的人员知道的两位数码来发出信号。代码的第一个数字是指主叫方必须等待的呼叫铃声或振铃之间的静音间隔数，然后再从触摸音上的十个数字中的一个或使用的电话上的旋转拨号上输入代码的第二位数拨打电话。首先检测到来电并进行电子应答，然后通过开放的电话线周期性地发送正弦波发生器的输出，以产生模拟传统电话的周期性可听振铃序列的虚假呼叫音。启用电路仅在假呼叫音序列中的适当的无声间隙期间检测正在发信号的正确码。触摸音解码器电路或旋转拨盘检测器电路都能够产生用于激活诸如钟或光的换能器的输出，以指示已经接收到期望的呼叫。如果传感器被激活，则扩展虚假呼叫音序列以提供用于应答电话的额外时间，并且当扩展序列结束时，呼叫被终止。即使在正确的无声间隙期间没有检测到正确的代码，假呼叫音发生器继续产生虚假呼叫音，直到主叫方挂断或直到产生最大数量的虚假呼叫音，之后筛选器自动终止循环并重置以接收下一个来电。

摘要： A ski transporting device which can carry three or more pair of skis, boots and poles. The device comprises three main components; 1, a two wheeled component detachably mounted to 2, a main or spine pair of skis and 3, a spanner support bar again detachably mounted to the spine pair of skis. This bar supports two or more additional pairs of skis which, in conjunction with the main pair, form a cradling space in which additional skis, ski poles and boots can stored and thus transported. An optional handle mounts on the opposite end of the main pair of skis to facilitate pulling the loaded device.

摘要： A pencil holder which can be detachably mounted to the sweat band area of a soft baseball type cap preferably formed in one piece of moulded plastic. It includes a base section arm (12), an outwardly and upwardly extending opposing outer arm (13) between which the pencil is frictionally held and an inwardly and upwardly extending opposing inner arm (11), which in combination with the base section arm (12), forms a clamp or clip which firmly grasps the sweat band area of the cap. All three arms extend end to end of the holder, forming in essence, two upwardly facing clamps or clips.
