摘要： A method and apparatus to regulate the inflation of objects. To start inflation, the apparatus couples a fluid source to the object via a plenum. Concurrent with inflation, the apparatus substantially continuously measures pressure within the plenum using a sensor sufficiently proximate the object such that pressure measured by the sensor is substantially similar to pressure within the object. When measured pressure exceeds a target pressure by a prescribed margin, the apparatus stops inflating. While inflation is stopped, the apparatus reads pressure measured by the sensor and deflates the object as needed to reduce measured pressure to the target pressure.

摘要： A fluid level sensor for use in a chamber contained in a surgical cassette. The sensor has a pair of parallel conductor that project vertically into the chamber forming an open circuit. When surgical fluid contained within the chamber touches the conductor, the circuit is completed and AC voltage or current is passed through the conductor circuit. The conductivity of the circuit can be measured and related to the depth of fluid covering the conductors using laboratory-generated data or in situ calibration of the cassette.

摘要： An acoustic fluid level sensor for use in a chamber contained in a surgical cassette. The sensor has an ultrasound transducer mounted on the outside of the bottom of a fluid chamber and is acoustically coupled to the chamber. The transducer sends a pulse ultrasound signal through the chamber and any liquid in the chamber. The signal is reflected back by the air/liquid interface and captured by the transducer. The time required for the signal to travel to and from the transducer will vary with the amount of fluid in the chamber and is indicative of the level of fluid in the chamber.

摘要： An improved method for adaptively cancelling acoustic feedback in hearing aids and other audio amplification devices. Feedback cancellation is limited to a frequency band that encompasses all unstable frequencies. By limiting the bandwidth of the feedback cancellation signal, the distortion due to the adaptive filter is minimized and limited only to the unstable feedback regions. A relatively simple signal processing algorithm is used to produce highly effective results with minimal signal distortion.

摘要： A method for operating a peristaltic pump having a molded flow channel contained on an elastomeric sheet that is bonded or mechanically attached to a rigid substrate. The pump head rollers are mounted radially from the axis of rotation of the pump motor and compress the elastomeric flow channels against the rigid substrate. During reflux, the pump head is positioned so that at least one of the rollers compresses the elastomeric flow channel at the input end of the peristaltic pump. Such an operation minimizes the amount of the elastomeric sheet that is exposed to high transient pressures.

摘要： The insertion effects of hearing aids are determined and compensated to restore the ability to have directional hearing in individuals wearing hearing aids. In one aspect a method involves finding the ratio of the unaided head related transfer function to the aided head related transfer function and then designing a hearing aid filter that is the inverse of that derived insertion effect, thereby restoring the ability to hear interaural differences in aided systems both in level and in time of arrival to improve hearing in the presence of noise. The insertion effects can be derived either through frequency domain analyses, using the above-mentioned transfer function calculations and measurements, or in another aspect through time domain analyses, using optimal filter calculations and measurement obtained using a successive data acquisition system that is subsequently time aligned by recording trigger pulses with the data.
