Abstract: An earpiece of an ANR device incorporates one or more of feedforward-based ANR; feedback-based ANR; passive noise reduction (PNR) of environmental noise sounds in the environment external to the casing of the earpiece in higher audible frequencies; a controlled leak acoustically coupling the front cavity to the environment external to the casing of the ANR device where the coupling may be through another cavity that is closable to the environment external to the casing with a leaky cover; a combination of an acoustically resistive port and a mass port coupling a rear cavity to the environment external to the casing where the coupling may be through another cavity that is closable to the environment external to the casing with a leaky cover; a feedforward microphone given acoustic access to the environment external to the casing through an aperture that is overlain with a leaky cover or that is enclosed within a cavity that is acoustically coupled to the environment external to the casing with a leak.

Abstract: A method, system, and computer program for concurrent in-application programming of programmable devices, such as microcontrollers, provides the capability to concurrently program multiple programmable devices that are installed in systems. A method for programming programmable devices in a system comprises determining a status of a first plurality of programmable devices, the status including information relating to program code in each programmable device, determining a subset of the plurality of programmable devices that is to be programmed, based on the information relating to program code in each programmable device; where in the subset includes a second plurality of the programmable devices, programming the second plurality of programmable devices concurrently, and determining a status of the second plurality of programmable devices, the status including information relating to success of concurrent programming of each programmable device.

Abstract: An apparatus and method for radiographic image includes a plurality of light emitting diodes two of which produce light in the optical or visible wavelengths, another one of which produces light in an infrared wavelength so that pumping light can be supplied to a variety of radiographic substrate media. The pumping light is supplied to the medium by a plurality of optical fibers arranged in a linear array as the medium is scanned beneath the fibers. A second plurality of linear optical fibers picks up phosphorescent emissions from the radiographic medium due to the pumping light excitation and supplies the emissions to a photodiode or other optical receiver where the light intensity is translated into an electrical signal. The signal is sent to a processor which generates an image signal. The image signal may then be converted into an image representative of the latent x-ray image on the radiographic medium.

Abstract: A system that accepts and stores raw time and expense data for a plurality of businesses—each business defining a separate account that is accessible and usable by authorized users for the particular business. The inventive system automatically converts the raw time and expense data by considering any client or project-specific billing requirements (e.g., flat-fee, maximum fee, discount, write-offs, etc.) and by applying such specific requirements to the raw time and/or expense data in generating an invoice. The raw data may be referred to as internal data in that it is used only by the business providing a service to their client, and in connection with that business's account by the inventive system. A client will not have access to internal data. The invoice data, on the other hand, may be referred to as external data because it is communicated to the client and also used in connection with that business's account.

Abstract: A visual display has an increased readout capability due to its operation the transflective mode. A source of ambient light and light for radiation through the display from the backside together assure the increased readout capability. Heretofore, ambient light would degrade or washout a display making it nearly impossible for monitoring personnel to decipher alphanumeric or pictoral displays due to the decreased contrast. A pair of linear polarizers sandwich a twisted nematic liquid crystal and have their polarization axes either parallel or mutually orthogonally disposed so that the crystal will present bright or dark areas in response to applied potentials. Because a partially transmitting mirror is interposed between the sandwiched liquid crystal and the radiating light source, the ambient light augments the radiated light to enhance the visual display.

Abstract: Light energy data is generated in sequential interlaced field raster format y a sensor driven in azimuth to detect a panoramic scene. The light energy data is sequentially recorded together with an azimuth rate signal which is a function of the rate that the sensor is driven in azimuth. Because the sensor has been driven in azimuth, however, there is a delay in the sequential detection between first and second interlaced fields of any selected frame of the panoramic scene; consequently, when it is desired to retrieve and playback a "stop-action" image comprised of a selected frame, compensation must be made for the delay. The recorded azimuth rate signal is used to develop a commensurate delay between the two sequential first and second interlaced fields of light energy data comprising the selected frame of light energy data which is desired to playback in "stop-action" form.

Abstract: An electro-optical system for performing matrix-vector multiplication includes a mask having a plurality of elements of substantially equal resolution area disposed in a matrix of M rows and N columns, each element containing recorded discrete information as defined by its degree of opacity which is representative of a predetermined mathematical value in a known matrix. A light source is positioned to illuminate the mask and has its intensity modulated as a function of the sequential values in a N X 1, vector. A multiple photo-responsive array including M elements disposed in a column is positioned to receive the light energy transmitted by the illuminated mask and generates signals at each element commensurate with the instantaneous photo energy received at its position.

Abstract: A multi-channel optical correlation system employs a light source to illuminate a mask having a plurality of linearly disposed channels, each of which has recorded information defined by variations in opacity along its linear length. The light source is modulated as a function of an unknown input signal. A multiple element charge coupled device having its elements arrayed in linearly disposed groups along axes parallel to the linearly disposed channels of the illuminated mask is positioned to receive the light energy transmitted by the illuminated mask for developing a charge within each such element commensurate with the photo energy received at its discrete position.
