The device can optionally contain integral testing or analysis component (83) for receiving the sample and providing testing or analysis indication or readout for the user. A method involves piercing the skin at a rapid rate, kneading the surrounding area by ultrasonic action, piezoelectric or mechanical oscillation to stimulate the blood flow from the wound, drawing the fluid using a pumping system.

Coding free text documents, especially in medicine, has become an urgent priority as electronic medical records (EMR) mature, and the need to exchange data between EMRs becomes more acute. However, only a few automated coding systems exist, and they can only code a small portion of the free text against a limited number of codes. The precision of these systems is low and code quality is not measured. The present invention discloses a process and system which implements semantic coding against standard lexicon(s) with high precision. The standard lexicon can come from a number of different sources, but is usually developed by a standard's body. The system is semi-automated to enable medical coders or others to process free text documents at a rapid rate and with high precision. The system performs the steps of segmenting a document, flagging the need for corrections, validating the document against a data type definition, and looking up both the semantics and standard codes which correspond to the document's sentences. The coder has the option to intervene at any step in the process to fix mistakes made by the system. A knowledge base, consisting of propositions, represents the semantic knowledge in the domain. When sentences with unknown semantics are discovered they can be easily added to the knowledge base. The propositions in the knowledge base are associated with codes in the standard lexicon. The quality of each match is rated by a professional who understands the knowledge domain. The system uses this information to perform high precision coding and measure the quality of the match.

Fourier domain a/LCI (faLCI) system and method which enables in vivo data acquisition at rapid rates using a single scan. Angle-resolved and depth-resolved spectra information is obtained with one scan. The reference arm can remain fixed with respect to the sample due to only one scan required. A reference signal and a reflected sample signal are cross-correlated and dispersed at a multitude of reflected angles off of the sample, thereby representing reflections from a multitude of points on the sample at the same time in parallel. Information about all depths of the sample at each of the multitude of different points on the sample can be obtained with one scan on the order of approximately 40 milliseconds. From the spatial, cross-correlated reference signal, structural (size) information can also be obtained using techniques that allow size information of scatterers to be obtained from angle-resolved data.

A multichannel cochlear implant system spatially spreads the excitation pattern in the target neural tissue by either: (1) rapid sequential stimulation of a small group of electrodes, or (2) simultaneously stimulating a small group of electrodes. Such multi-electrode stimulation stimulates a greater number of neurons in a synchronous manner, thereby increasing the amplitude of the extra-cellular voltage fluctuation and facilitating its recording. The electrical stimuli are applied simultaneously (or sequentially at a rapid rate) on selected small groups of electrodes while monitoring the evoked compound action potential (ECAP) on a nearby electrode. The presence of an observable ECAP not only validates operation of the implant device at a time when the patient may be unconscious or otherwise unable to provide subjective feedback, but also provides a way for the magnitude of the observed ECAP to be recorded as a function of the amplitude of the applied stimulus. From this data, a safe, efficacious and comfortable threshold level can be obtained which may be used thereafter as the initial setting of the stimulation parameters of the neurostimulation device, or to guide the setting of the stimulation parameters of the neurostimulation device.

A method of, apparatus for, and computer-readable medium for rapid, real time kinematics determination requiring lowered information transmission for position updates than traditional RTK systems. Position signals are received from a base station and roving system and a compressed position signal is received from the base station. A position estimate using an integrated method is determined using the received position signals from the base station and the roving system and the compressed position signal from the base station. Ambiguity resolution of the position estimate is enhanced by applying a quality control procedure using derived validation criteria. A second position estimate is derived based on the enhanced ambiguity resolution. Because of the use of the compressed position signal smaller transmissions may be performed at a more rapid rate providing a higher position update rate.

Ammonium sulfate nitrate composite materials useful as fertilizers having desirable levels of nitrate ions, superior stability against detonation, higher density, greater resistance to moisture, and a method for their manufacture. The ammonium sulfate nitrate composites have as essential constituents ammonium sulfate and the NH4SO4.2(NH4NO3) double salt with less than 5 wt. % in combined total of the more hazardous NH4SO4.3(NH4NO3) double salt and ammonium nitrate. The composites of the invention are formed by reacting ammonium sulfate with ammonium nitrate in a molar ratio of about 0.9:1 to about 1.1:1 in the presence of a small amount of water in a narrow range of temperatures and then cooling to solidification at a sufficiently rapid rate to prevent macroscopic segregation of the reaction products.

Aspects of the present disclosure relate to the brewing of beverages from a liquid, such as water, and a flavor base, such as tea, cocoa, or coffee. Specifically, aspects of the present disclosure enable the brewing of beverages with a level of precision that can yield a uniform taste from cup to cup, and at a rapid rate. In one embodiment, a liquid is heated in a reservoir to a predetermined temperature. Prior to brewing a beverage with the liquid, the liquid may be passed through a temperature control unit to cool the liquid to a desired brewing temperature. By utilizing such a temperature control unit, the brewing temperature can be varied on a per-beverage basis. Moreover, utilization of a temperature control unit can enable the liquid to be brought to a desired brewing temperature relatively rapidly.

Apparatus for blast freezing palletized products is disclosed in which tall racks have openings on at least one side that connect to a plenum chamber, against which stacked pallets can be placed one above another as well as beside one another adjacent the plenum openings, but with the rack providing only one pallet depth to optimize circulation of regular warehouse freezing air through the pallets at a rapid rate for rapid blast freezing.

As another example, there are vertically adjustable panels in a tall rack to accommodate different height palletized products stacked one above another, in a way that allows for sealing between the plenum chamber and the palletized products on one side of the palletized product without either substantial blockage of air flow through the side of the palletized product and without allowing a substantial gap between the palletized product and the plenum that would allow a substantial bypass of flow through the palletized product. In particular, as to a particularly preferred embodiment of the invention, there is disclosed the fixing of the position of adjustable panels through the use of pins that could be inserted into any one of a series of vertically arranged holes to achieve any one of multiple discrete heights that are securely positioned, yet readily adjustable. The vertical adjustability of a member that has a rigid component that may or may not also contain a cushioned or flexible seal allows for much more durability, versatility and suitability for accommodating palletized products of various heights.

A system and method for relating heart rate and power output during exercise includes subjecting an individual to a physical activity that involves maintaining power output at a substantially constant level during a time period while monitoring heart rate. For an initial portion of the time period, there is a generally parallel correlation between power output and heart rate. Subsequently, a separation point occurs at which heart rate increases at a relatively rapid rate while power output remains relatively constant, which provides an accurate indication of the individual's anaerobic threshold. The separation point may be used to determine an exercise regimen for the individual, which may be used in a variety of ways, including in weight loss or maintenance, athletic training, physical therapy, etc. The physical activity may involve operation of an item of exercise equipment, such as a cycling exerciser, which includes means for sensing power output by the individual.

A method and apparatus for continuously or at a rapid rate of repetition measuring friction between a road surface and a tire, especially suitable for evaluating the severity of visually undetectable road ice at traffic speeds, consists of a separate test wheel attached to a vehicle and in contact with a road surface, wherein a controlled slippage of test wheel is created by a compressed spring acting either clockwise or counterclockwise to a hinge with a substantially vertical axis upon which the test wheel arm pivots. Electrical signals are produced varying in accordance with the angle of yaw, the signals being transmitted to an onboard computer or remote receiver. A suspension system links the test wheel to the vehicle.

A method of designing an earth-boring rotary drill bit includes designing a bit body and cutting elements of the drill bit such that features of the drill bit other than cutting elements engage and rub against the subterranean formation being drilled by the drill bit at depths-of-cut beyond, but close to, an intended median depth-of-cut, and such that the amount of rubbing area between such features and the formation increases at a relatively rapid rate as the depth-of-cut increases beyond the intended median depth-of-cut. Such methods may be employed to mitigate the occurrence of the stick-slip phenomenon during drilling. A method of fabricating a drill bit includes configuring a bit body and cutting elements in accordance with such a design. Earth-boring drill bits include a bit body and cutting elements so configured.

An electrical, automatic hot beverage brewer (10) and method of brewing in which a removable brew chamber (20) has a drain hole (25) in the bottom fitted with a normally closed, pressure responsive brew chamber drain valve assembly (24) maintained in a normally closed position except when pressure against the drain valve (24) exceeds a preselected minimum pressure limit that is greater than the fluidic pressure applied by virtue of head pressure of a full load of hot water and a piston (74) is moved within the brew chamber to control the opening and closing of the drain valve (24) When the piston (74) moves downwardly toward the drain hole the air pressure of a pocket of air (90) above the beverage (92) in the brew chamber (20) is increased to open at the end of a seeping period when it is desired to rapidly expel freshly brewed beverage out the brew drain valve at a relatively rapid rate depending upon the total of the hydraulic pressure and the added pressure from the air pressure source to avoid the need to wait for the end of a drip period. The drain valve (24) automatically closes after the piston (74) is removed from the brew chamber (20) to enable removal of the brew chamber (20) from a brewer housing (12) without risks of hot beverage leaking out of the brew chamber (20).

A radio base station (RBS) provides dynamic rate adaptation for rate-adjustable communication channels used to transmit information to remote mobile stations based on monitoring transmit power information associated with those channels. For a given channel, the RBS tracks an average channel power on a per transmit frame basis and compares the average to first and second rate adjustment thresholds, which comparisons trigger downward or upward rate adjustments. Similar operation also may be based on averaging the power control commands returned by the mobile station, which indicate whether the channel's power as received by the mobile station is or is not sufficient with respect to a desired signal quality. This method thus provides a mechanism for rapid rate adaptation without requiring explicit rate control signaling from the mobile stations.
