A receiver in an audio distribution system provides graceful degradation of audio quality as transmission quality decreases by dynamically adjusting the volume of audio output as a function of transmission quality. The receiver estimates the rate of transmission errors in a transmission link on which the audio signal is distributed by detecting errors in known information embedded in the audio signal. As the rate of transmission errors increases, the receiver increasingly attenuates the volume of the audio output. The receiver dynamically adjusts the volume relative to the rate of transmission errors applying a smoothing function to avoid disruptive rapid fluctuations in audio output volume.

An echo suppressor uses a multi-state operating sequence to provide non-disruptive monitoring of a remotely broadcast program during a performers live performance at a local site. The operating sequence is actuated by a voice activated switch that initiates signal processing for correlating a locally originating audio (e. g. , the performers voice) to its echo in the broadcast program. During correlation states in the operating sequence, the echo suppressor switches monitoring to a local microphone signal to allow the performer to hear his or her own voice while preventing echo from being heard before correlation is achieved and echo suppression can begin. The correlation states include an initial correlation at a reduced sampling rate to detect echo within a wide delay time window and determine the locally originating audio is on-the-air. A subsequent state then performs a second correlation at a higher sampling rate to correlate to the echo in a narrower delay time window displaced according to the approximate delay determined in the initial correlation.

A beverage mixing and dispensing valve, or a beverage dispenser including the valve, includes an automatic shut-off features. A user presses a cup or container against a lever on a soft-drink dispenser. The lever closes a switch to activate the opening of a solenoid-operated valve. At the same time, a detection circuit is monitored to determine whether overflow of drink or foam has occurred. When drink or foam overflows and bridges a gap between two metal conductors on the lever, resistance is lowered and electricity flows in the detection circuit. The valve then automatically shuts off the flow of beverage. Energy is saved in keeping the valve open using a pulse width modulation (PWM) technique for voltage to the solenoid, rather than using a steady-state voltage.

A diagnostic instrument for sources of electrical system discharges provides a map interface for controlling playback of collected signal traces. A map pane of the interface displays a map of an area illustrating a path along which signal data was collected. A double click input selecting a location on the path causes playback of a waveform for the recorded signal in a signal pane commencing from the selected location.

In one embodiment the present invention includes a radio frequency identification (RFID) system with a shorting loop. The shorting loop at least partially surrounds the antenna. The shorting loop distorts the electromagnetic field generated by the antenna to improve the definition of the border of the read region of the antenna. In this manner, the RFID system provides more accurate discrimination between RFID tags inside the read region versus RFID tags outside the read region (i. e. , improves the accuracy of determining that a particular RFID tag is inside the read region).

An embodiment of the present invention improves the efficiency of radio frequency identification (RFID) systems and helps to extend the effective read range for certain configurations of closely spaced RFID tags. Specifically, an embodiment helps to minimize energy losses that result when there is excess energy from the excitation source. This excess energy has the potential to damage the circuitry in RFID tags. A shunt regulator is often used to protect the RFID circuitry by clamping the voltage, but has the undesirable effect of converting this excess excitation energy into heat. Various embodiments are directed toward using only as much of the excitation energy as necessary to power the RFID circuitry. These embodiments include circuitry for a constant current power supply that can be implemented either with discrete components or built into a new ASIC design; a network that minimizes the amount of energy that is converted to heat by the shunt regulator built into many RFID circuits; and/or a sleep mode for reducing the energy consumed by an RFID tag after it has been read. An embodiment may have the benefit of making more of the excitation energy available to power other RFID tags nearby—thereby improving system performance and read range.
