Title: Plural-order sigma-delta analog-to-digital converters using both single-bit and multiple-bit quantizers
Inventor: RIBNER DAVID B
IPC: H03M3/00
Filed: 1991-10-03
Abstract: PLURAL-ORDER SIGMA-DELTA ANALOG-TO-DIGITAL CONVERTERS    USING BOTH SINGLE-BIT AND MULTIPLE-BIT QUANTIZERS                       ABSTRACT OF THE DISCLOSURE       An oversampling converter of a type using a plural-order, plural-stage sigma-delta modulator, the output signal to the decimating filter of which modulator has the quantization noise contribution of a number of its plurality of stages suppressed therein, uses single-bit quantization in those stages, and the modulator uses single-bit quantization in those stages. Those stages each employ digital-to-analog converters with single-bit resolution in their feedback connections to avoid non-linearity problems. Another sigma-delta converter stage, the quantization noise of which appears in substantial amount in the converter output signal to the decimating filter, uses quantization having multiple-bit resolution to help increase the resolution of the oversampling converter overall. This other sigma-delta converter stage also employs a digital-to-analog converter with single-bit resolution in its feedback connection in order to avoid non-linearity problems, with additional circuitry being used to compensate for the digital-to-analog converter having single-bit, rather than multiple-bit, resolution.

Title: Information processing system for counting coughs
Inventor: STEINER SOLOMON S
IPC: A61B5/11
Filed: 1991-04-19
Abstract: A system using audio and visual information to count coughs or evaluate other discrete information, including respiration and heart rate, relating to a patient in a fixed location such as a bed (46) is disclosed. The system provides movement- and sound-based information derived from the patient's activities to a storage device (26) and subsequently to a signal processing apparatus. One embodiment of the invention includes a pressure transducer (14), a video camera (18), a directional microphone (22), and a videocassette recorder (VCR) having two audio channels. Signals obtained from the transducer (14) and microphone (22) are transmitted to the two audio channel inputs of the VCR, while movement of the patient is recorded using the video camera (18) connected to the video channel input of the VCR. Part or all of the information stored using the VCR may be transmitted to signal processing equipment and frequency filtered to determine the presence and number of coughs, and any remaining information (e.g. the video data) may be used to confirm the count. Because various conditions manifest themselves in movements having different frequency characteristics, the present system, as appropriately modified, also can be used to determine the presence of symptoms such as restlessness and thereby evaluate the effectiveness of medicines such as sedatives and hypnotics.

Title: Method for metallizing surfaces by means of metal powders
Inventor: LAUDE LUCIEN D
IPC: C23C24/00
Filed: 1992-02-17
Abstract: ABSTRACT OF THE DISCLOSURE       "Method for metallizing surfaces by means of metal powders"         The method for metallizing the surface of dielectric materials accordingto the invention comprises a first step wherein a metal powder, the size of the grains of which is comprised between 10 and 5000 nm, is deposited and then incorporated into the surface of the dielectric material. In a second step of the method, the dielectric material which is so impregnated with metal, is immersed into an autocatalytic bath to coat the impregnated zones of the material with a layer of the metal contained in the bath in a thickness which is proportional to the immersion time. This method enables to metallize materials such as oxides, polymers and composites containing these oxides and/or these polymers. The characteristics of the metal deposits are controlled, on the one hand, by the type of metal, and the size and the geometry of the metal powder grains and, on the other hand, by the type and the structure of the dielectric materials coated with these deposits.
