Abstract: A quantitative electroencephalograph (QEEG) based method and system for automatically controlling anesthesia is called a Closed Loop Anesthesia Controller (CLAC). An anesthetic is administered until the patient has attained the desired plane of anesthesia and a QEEG self-norm is then obtained. If the patient's brain waves exceed a confidence interval, centered at the set-point of the self-norm, the administration of the anesthesia is automatically adjusted.

Abstract: Two methods, "Adjusted Winner (AW)" and "Proportional Allocation (PA)," are provided for the fair division of a collection of items, which could be either real goods or issues in a dispute, between two claimants (parties). The methods can be implemented as a digital computer software program. In both methods, the parties are each given 100 points and then bid on each item using their points. Under the AW method, which is applicable to indivisible items, each party is initially allocated those goods, or wins on those issues, for which it bids the higher number of points. Then the goods or issues are reassigned, or resolved differently, to achieve equality of points based on the quotients of the parties' bids. Under PA, each good or issue is divided according to a ratio based on both parties' bids for that good or issue.

In one embodiment the web is partly covered by custom-fitted curved plates. The flexible web areas between the plates comprise hemispherical or disk protrusions. In another embodiment, without plates, the protrusions on the web are disks and the areas between the disks are covered by other disks.

Abstract: An electrosurgical scalpel includes a hand-held tubular housing having a cable which extends from the housing to an electrosurgical current generator. At least two, and preferably three, conductive blades are retractable to within the housing. The surgeon, using a finger, may selectively extend one blade at a time, so that the extended blade protrudes through a front (distal) orifice of the housing. The blades are different in size and/or shape from each other and may, by finger operation of a switch mounted on the housing, be used for cutting tissue or, alternatively, for applying coagulation current.

Abstract: A projector system includes a light pipe integrator (LPI) between its lamp and its projection lens system. The LPI is hollow, formed from sheet metal, and has an internal cold mirror coating which reflects visible light and passes infra-red radiation. The reflector is a compound reflector having profiles of two ellipses with different eccentricities.

Abstract: A projector system includes a lamp, a reflector collector optic, a light pipe, a Polarizing Beam Splitter (PBS), and an LCD (Liquid Crystal Display) panel. The light pipe has a square or octagonal entrance pupil, reflecting internal walls coated with a cold mirror coating, is tapered in shape, and has a rectangular exit pupil. The PBS converts an unpolarized beam from the exit pupil of the light pipe into a uni-polarized beam which it directs to the LCD panel.

Abstract: To satisfactorily transmit two-way speech on digital computer networks, such as the Internet, it is necessary to reduce unpredictable delays due to variations in loading, routing and other factors. The present invention transmits extra packets of specially computed data along with the data representing speech. These extra packets are used at the receiving server to reconstruct any missing or late data packets. In one embodiment, any single packet of missing data in a stream of packets may be reconstructed. In additional embodiments, multiple packets of missing data may be reconstructed. This method is particularly suited to eliminating or reducing delays in networks in which data is sent down multiple diverse paths. Unlike prior art, it is not necessary to send full sets of redundant data down these diverse paths. The present invention significantly reduces latency with only a fraction of the added network bandwidth required with prior art methods that use full sets of redundant data.

Abstract: A method and system to prevent auto theft from parking areas, such as airport parking lots, includes a ticket dispenser, at an entry gate, which issues a numbered ticket to each driver. The driver is advised to carry the ticket with him and not to leave it in the car. At the same time the ticket is issued, the a part of its license plate number, is automatically determined and entered into computer memory, in association with the ticket number. At the exit, the ticket is presented by the driver, read by a ticket reader, and its associated license plate data is retrieved from computer memory. Also at the exit, part of the license plate of the car is again automatically obtained and compared with the license plate data retrieved from the computer memory. In the event of a mismatch, a warning signal is generated.

Abstract: In medical convulsive therapy (CV), comprising electroconvulsive therapy (ECT) and magnetoconvulsive therapy (MCT), a computer system is used to analyze the effectiveness of the treatment. In one embodiment the effectiveness is determined by measuring the physiological effects on the heart (ECG) muscles (EMG) and brain (EEG).

Abstract: A projector system includes a lamp, a reflector collector optic, relay optics to image the light from the light pipe exit pupil to the image gate, a light pipe and an image forming means such as a film gate or an LCD (Liquid Crystal Display) panel. The light pipe has a round or octagonal entrance pupil, reflecting internal walls, is tapered in shape, and has a rectangular exit pupil which is larger than a center section in cross-section. The light pipe mixes the light, by internal reflection, and produces light which is uniform in color and intensity across the exit pupil.

Abstract: A method in computer networks in which a client machine (playback client computer) requests multimedia files, such as compressed video clips, from a server (storage server computer). The transmission uses digital data packets. In the case of video files, the packet headers identify the video frame and the sequence number of each packet derived from the frame. The transmission timing is not based on a steady byte stream or an average of bytes to be transmitted. Instead, in the case of video, the frame rate determines normal transmission and a frame is transmitted during each frame time. The client agent has a normal packet buffer, normally holding 1-5 video frames. The transmission rate is adjusted to keep that buffer filled within its normal range. The timing information required for transmission, in one embodiment, is stored in a separate index file associated with each multimedia file.

Abstract: A method which is accurate and yet relatively simple, rapid and inexpensive for estimating 3-D coordinates of EEG (electroencephalograph) electrode positions on the head. The electrode positions of any number of scalp electrodes placed according to the standard 10/10 electrode position system are computed by a computer system based on 14 manually measured inter-electrode distances and 9 electrode-to-skull landmark straight-line distances. The measurements are made manually using digital calipers.

Abstract: A magnetic induction coil is placed next to the scalp of a patient. A pulse train of high energy electrical waves is flowed through the induction coil to produce a sufficiently strong magnetic field to generate currents in the patient's brain for the therapy of neurologic or psychiatric illnesses. These currents induced in the brain cause multifocal neuronal discharge to induce a generalized convulsive neuronal discharge.

Abstract: A cervical biopsy device utilizes a biopsy needle having a magnifying lens which may be mounted directly on a cutting sheath. The magnifying lens also acts as a barrier to prevent excessive penetration into the tissue. The components of the biopsy needle, which include a stylet, the cutting sheath and the magnifying lens may be constructed as a single, disposable unit. In a method of using the biopsy device of the invention, the magnifying lens is used to observe the initial insertion of the stylet and sheath into tissue as well as the cutting and removal of the tissue.

Abstract: A laparoscopic surgical instrument to perform tubular ligation of the Fallopian tube includes a handle grip to be held by the surgeon. A finger grip is used to slide a body member on a rod fixed to the handle and to squeeze a staple onto the Fallopian tube. A forceps, operated by a button on the handle, pulls up the Fallopian tube and holds a segment of the tube, as a biopsy sample, after it has been severed.

Abstract: A subscriber broadcast system broadcasts encrypted fax (facsimile) messages on an FM subcarrier. The subcarrier is received by an FM data receiver which includes an FM receiver tuned to a selected FM subcarrier, a subcarrier detector and a demodulator. A fax message, having the subscriber's address, is received, decrypted, and stored in memory. When the subscriber's fax machine is not busy, i.e., not receiving a fax over a telephone line, the FM data receiver transmits handshake signals and then transmits the stored fax message to the subscriber's fax machine.

Abstract: A portable air sampler to measure the concentration of a chemical compound in the air, especially in a workplace, measures the quantity of the chemical in its gas phase and in its particle phase. The sampler is connected to a pump which draws ambient air through an inlet tube and out a nozzle. A housing holds a filter aligned with the nozzle. The air is immediately separated into two parts, one portion continues straight through the filter, the second turns 180.degree.. The particles, due to their mass and resulting inertia, will travel in the forward direction to be collected in the filter. The portion of air that flows through the filter continues through a sorbent tube where the vapor (gas phase) from this portion is collected. This sorbent tube also collects the quantity of the chemical that evaporates from the particles collected on the filter.
