Show moreA multiple emulsion of aqueous oxygen carrying material in oil in outer aqueous phase is suitable for provision of oxygen for oxygen transfer processes. A hemoglobin multiple emulsion in physiologically compatible oil in an outer aqueous saline solution is provided in sufficiently small droplet size to provide oxygen flow through blood vessels to desired body tissues or organs thereby providing a blood substitute. A process is provided wherein hemoglobin, a fragile material, is formulated into high hemoglobin content water-in-oil-in-water multiple emulsions while maintaining high yields and high oxygen exchange activity.

Show moreThe disclosure describes a technique for uniform heating of relatively large blocks of hydrocarbonaceous formations in situ using radio frequency (RF) electrical energy that is substantially confined to the volume to be heated and effects dielectric heating of the formations. An important aspect of the disclosure relates to the fact that certain hydrocarbonaceous earth formations, for example raw unheated oil shale, exhibit dielectric absorption characteristics in the radio frequency range. In accordance with the system of the invention, a plurality of conductors are inserted in the formations and bound a particular volume of the formations. The phrase "bounding a particular volume" is intended to mean that the volume is enclosed on at least two sides thereof. Electrical excitation is provided for establishing alternating electric fields in the volume. The frequency of the excitation is selected as a function of the dimensions of the volume so as to establish a substantially non-radiating electric field which is substantially confined in the volume. In this manner, volumetric dielectric heating of the formations will occur to effect approximately uniform controlled heating of the volume.

Show moreAn intranet mediator for obtaining direct answers to natural language questions allowing users to search both a data warehouse of integrated/structured data sources and unstructured data sources. The intranet mediator allows the user to obtain an answer to a natural language question without having to surf the data sources in which the answer might be contained, or without being limited to one specific factual item return. The intranet mediator operates on the supposition that most answers to business queries are contained within structured data sources which have been integrated into the data warehouse thereby having common schema and known contents. Preselection of the most relevant data source(s) is thus possible before query output. Search of unstructured data is also performed for additional context surrounding either the question or the answer. A direct answer is given in response to the question. If desired, the intranet mediator may also display a list of data sources where additional relevant information may be found.

Show moreA video tape cartridge of endless loop configuration capable of tape speeds suitable for longitudinal scan television recording while providing one hour or more of continuous playing time on one-quarter inch width tape. In an illustrative embodiment tape guides within the cartridge are shiftable from a loading position to an operating position without a substantial change in the length of the tape path to accommodate scanning of the tape at a tensioned loop closely adjacent the capstan. In operating condition, the tape is engaged with the capstan at one side thereof so that the capstan pulls tape along an incoming tape path from the inner side of the coil, the tape passing about the tensioned loop past the transducer head and again engaging the capstan for supply of the tape to the outer side of the coil along an outgoing tape path, with a tape drag applying a substantial drag force to the tape at the incoming tape path between the reel and the capstan.

Show moreA method and apparatus for prefetching data from memory for a multicore data processor. A prefetcher issues a plurality of requests to prefetch data from a memory device to a memory cache. Consecutive cache misses are recorded in response to at least two of the pluarlity requests. A time between the cache misses is determined and a timing of a further request to prefetch data from the memory device to the memory cache is altered as a function of the determined time between the two cache misses.

Show moreA method and apparatus for eliciting a physiologically significant cough reflex, such as in a quadriplegic patient. The apparatus preferably has at least one pair of electrodes which are positioned about or near the abdominal muscles. The user generates an input signal. The input signal and a stimulus pulse signal are computed into an output signal. Prior to the delivery of the output signal, alerting signals are delivered to the user to alert the user of an upcoming cough and the onset of pulse electrical voltage to allow the user to engage appropriate volitional activity to optimally engage and complete the cough. The output signal is transformed into a pulse electrical voltage which is delivered across each pair of electrodes. Such pulse electrical voltage activates the lower motor neurons and thereby contracts the abdominal muscles to elicit a physiologically significant cough reflex. The pulse electrical voltage can be delivered at an optimum time, which can be calculated as a function of a physical and temporal status of the cough and a volitional activity by the user, in order to achieve a maximum air flow rate of the cough.
