摘要： A connection verification system that provides substantially non-intrusive connection verification for an optical switch, achieved by correlating the low-frequency contents of the input and switched signals. The results of the correlation process are compared against a connection map to determine whether the switch has operated correctly and to identify, if possible, which mis-connections have taken place. The system includes a selection unit for controllably admitting individual ones of the input signals and individual ones of the switched signals and a verification unit connected to the selection unit, for controlling operation of the selection unit as a function of a connection map and performing relative-delay-dependent signal processing operations on the signals admitted by the selection unit so as to identify connections established through the switching unit and determine their consistency with the connection map. The relative-delay-dependent signal processing operations may be based on correlation or anti-correlation, depending on the operational requirements of the invention.

摘要： This invention describes a loudspeaker implementation which can adaptively reduce the transmission of an acoustic signal to listeners other than the intended listener. The invention uses a dipole loudspeaker implementation with two acoustic sources, each of which is driven by a separate signal. By introducing a predetermined phase difference between the signals produced by the two acoustic sources, the null in the standard dipole spatial directivity pattern may be moved to any desired direction. Alternatively, using a microphone close to the unintended listener's ears and a suitable feedback arrangement, the null can adaptively be aligned with the direction of minimum desired sound transmission. This invention, therefore, provides a solution for applications where it is preferable to reduce the transmission of sound in particular directions while providing the listener with headphoneless audio. In particular, the invention would be effective in applications which involve embedding the implementation into a headrest, seat or other object where the direction of minimum desired transmission is known. Since the invention only involves the use of presently available components, its implementation will not add much cost to an overall system.
摘要翻译：本发明描述了一种扬声器实现方式，该扬声器实现方式可以自适应地减小声信号向除了预期听众之外的听众的传输。本发明使用具有两个声源的偶极扬声器实现，每个声源由单独的信号驱动。通过引入由两个声源产生的信号之间的预定相位差，标准偶极子空间方向性图案中的零点可以移动到任何期望的方向。或者，使用靠近无意的收听者的耳朵的麦克风和适当的反馈布置，空值可以自适应地与最小期望声音传播的方向对准。因此，本发明为其中优选地减少传输的应用提供了解决方案的声音在特定方向，同时向收听者提供无耳声音频。特别地，本发明在涉及将实施方案嵌入到其中已知最小期望传输方向的头枕，座椅或其他物体中的应用中将是有效的。由于本发明仅涉及使用目前可用的组件，所以其实施不会给整个系统增加很多成本。

摘要： Portable wireless telephone handset with a flap movable upon a housing. In a first position the flap is close to a speaker to enable the flap to be disposed near to a user's ear for the user to receive personal low volume sound from the speaker. In a second position, the flap is further from the speaker to detract from use of the speaker near to the user's ear. In the second position of the flap, the speaker operates in loudspeaker mode. A switch is provided to change the speaker between loudspeaker and low volume sound mode, the switch operation being dependent upon flap position.

摘要： An electric field proximity detector capable of detecting partially conductive or conductive objects regardless of their impedance to circuit ground. The detector has a sensor with a transmitting electrode, a receiving electrode, and at least one circuit ground electrode preferably arranged in a bulls-eye configuration with the ground electrode between the transmitter and receiver electrodes. With appropriate sizing, upon the approach of an object, a signal received by the receiving electrode decreases, at least until the object is within a threshold distance of the sensor. The size and positioning of the ground electrode further reduces the effects of stray capacitance.

摘要： A battery has an electrode assembly that includes a positive electrode, a negative electrode, and a layer of electrolyte between the positive electrode and the negative electrode. An electric current flow in the positive electrode is unmatched to an electric current flow in the negative electrode, thereby producing a first magnetic field. A magnetic compensation structure is adjacent to the electrode assembly and has body of electrically conductive material connected to one of the positive electrode and the negative electrode. The electric current flowing through the electrode assembly also flows through the body in a pattern that matches the pattern of unmatched electric current in the electrode assembly. As a result a second magnetic field is produced by the magnetic compensation structure that opposes the first magnetic field thereby mitigating magnetic noise from the battery.

摘要： Handsfree telephony continues to be an increasingly desirable feature of modern telecommunications, whether in a conference room or mobile setting. Fundamental to the user acceptability of these systems is the performance of algorithms for acoustic echo cancellation, the purpose of which are to prevent the far-end signal from being transmitted back to the far-end talker. Most speech coding algorithms are based on some variant of Linear Predictive Coding (LPC), which reduces the amount of bits sent across a channel. Instead of doing echo cancellation in the time domain, the invention involves operating an acoustic echo canceller on the LPC parameters at the receiver, before the decoding stage.

摘要： A method and apparatus for setting the level of an analog signal supplied to an electronic device having a maximum input level. The method includes computing a gain which, when applied to the analog signal, causes the amplified signal to exceed the maximum input level for a percentage of time which is greater than zero, and applying the gain to the analog signal. When clipping occurs at least part of the time, the correlation result obtained for a pair of truly correlated signals remains virtually unaffected, while there is actually a beneficial effect on the correlation result obtained for a pair of truly uncorrelated signals. To determine the amplifier gain needed to attain the desired amount of clipping, the present invention capitalizes on the availability of power measurements taken from the signal before it was amplified. Reliance on feedback from the amplifier output is not required, resulting in a simplified gain computation process.

摘要： A post assembly process for enabling a manufacturer of acoustical communications apparatus, such as telephones and the like, to conveniently trim a sensitivity characteristic of an electret microphone therein, after assembly of the apparatus, whereby a uniform performance standard may be adhered to. When the acoustical sensitivity characteristic of the electret transducer is measured to be greater than a predetermined value, the transducer is exposed to X-ray radiation until the measured sensitivity characteristic has been reduced to the predetermined value.
