Abstract: An apparatus is provided to deliver carbon dioxide to an animal in a manner which allows the carbon dioxide to totally displace blood in an area of interest and to thus serve as a contrast media for angiographic procedures, or blood displacement media for angioscopic or laser procedures. The apparatus enables the carbon dioxide to flow at varied flow rates, the varied flow rates correlated to the varied flow rate of blood in the animal's vascular system. The flow rate of the carbon dioxide is variable during the course of a single injection. <IMAGE>

Abstract: An apparatus (10) and method for facilitating the respiration of a patient (36) are disclosed which are particularly useful in treating mixed and obstructive sleep apnea and certain cardiovascular conditions, among others, by increasing nasal air pressure delivered to the patient's respiratory passages just prior to inhalation and by subsequently decreasing the pressure to ease exhalation effort. The preferred apparatus (10) includes a patient-coupled gas delivery device for pressurizing the patient's nasal passages at a controllable pressure, and a controller coupled with the delivery device having a pressure transducer for monitoring the nasal pressure and a microcontroller (20) for selectively controlling the nasal pressure. In operation, the controller (20) determines a point in the patient breathing cycle just prior to inhalation and initiates an increase in nasal pressure at that point in order to stimulate normal inhalation, and subsequently lowers the nasal pressure to ease exhalation efforts.

Abstract: The system for determining a position of a probe relative to an object such as a head of a body patient. The head includes a surface such as a forehead having a contour. The head is placed in a cradle equipped with an arc. The cross-sectional images of the head are determined relative to the arc. A hand-held unit optically scans the forehead and the arc. During scanning to generate the cross-sectional images, the optical scanner is used to determine the position of the forehead relative to the cradle. During surgery, the optical scanner also determines the position of the forehead relative to a base ring. An array for receiving radiation emitted from the probe and from the base ring generates signals indicating the position of the tip of the probe relative to the base ring. A stereotactic imaging system selects and display the image of the head closest to the measured position of the tip of the probe.

Abstract: In an antenna for transceiver devices or the like, in order to eliminate the presence of separate modulators and demodulators and the associated circuits, according to the invention a detector/mixer diode (6) is associated with the radiating antenna structure (1), so as to form a single device which is alternately able to receive a modulated carrier wave and demodulate from the said wave the modulation signals received as well as modulate, with local modulation signals, a carrier wave, reflecting it for example back to the emitting source. The modulation signals received and the local modulation signals transmitted are respectively detected and supplied to the radiating structure (1) at a point (P) of the said structure, where the electric field of the carrier wave is equal to zero. The point of insertion (I) of the detector/mixer diode (6) in the radiating structure (1) is determined so as to obtain optimum matching between the impedance of the radiating structure (1) at the insertion point (I) and of the detector/mixer diode (6), during reception and transmission. <IMAGE>

Abstract: A system and method for digitally detecting the presence of analyte particles within a sample is disclosed herein. Each analyte particle is disposed to emit an optical response upon illumination in a known manner. The digital analyte detection system includes optical apparatus for illuminating a multiplicity of distinct pixel regions within the sample so as to induce each of the analyte particles included therein to emit at least one optical response. The pixel regions are dimensioned such that the number of analyte particles included within each region is less than a maximum detection threshold proportional to variability of the optical responses. The digital detection system further includes apparatus for measuring the emitted signal emitted from each pixel region. A data processing network receives the measurements of the emitted signals and, based on the measurements, counts the number of analyte particles within each pixel region so as to determine the number of analyte particles within the sample.

Abstract: A link quality improvement system for a cellular communication system in which portable units are used to facilitate communication of information signals between system users, via at least one cell-site, using code division multiple access spread spectrum communication signals. The system enables users to improve the quality of reverse communication links from the portable units to the cell-site by providing to each system user a link quality signal indicative of power received at the cell-site relative to an optimum level of received power. At a cell-site communicating with a portable unit associated with a particular system user, the portable unit transmitted power is measured as received at the cell-site. A command signal is generated at the cell-site and transmitted to the portable unit for adjusting portable unit transmitter power. The command signals are also accumulated in order to enable generation of a link quality signal in response thereto. In a preferred implementation the link quality signal is an audible interference signal inducing the system user to adjust orientation of the portable communication unit so as to improve signal quality on the reverse link.
