Abstract: Two data units are selected from main information, such as MIDI data,  into which additional information is to be incorporated, to calculate a difference between respective values of the two data units.  A particular data segment to be incorporated into one of the MIDI data units is selected from a group of data of additional information.  The size of the data segment to be incorporated into one of the data units may be either one bit or two or more bits.  Substitute data  to  replace  the  content  of  one  MIDI  data  unit  is generated on the basis of a predetermined function using, as variables,  the  data-related  value  and  a  value  of  the particular data segment, and the content of the data unit corresponding to a predetermined one of the two MIDI data units is replaced by the generated substitute data.   Thus, through such an electronic watermarking technique, any desired additional information can be incorporated into the MIDI data without  changing  the  MIDI  data  format.     In  another implementation, data of encoding information, representative of an encoding procedure, are incorporated dispersedly into particular data units belonging to a predetermined first data group of the main information,  and data belonging to a predetermined second data group of the main information are encoded by the encoding procedure represented by the encoding information.

Abstract: This application discloses an automated apparatus for cleaning the interior surface of a pipe.  The device includes a vehicle which propels itself down the inside of the pipe.          A cleaning system is fixed to the vehicle and uses arms to reach the walls of the pipe.  At the end of each arm sits a spray nozzle assembly equipped with spray nozzles.  The spray nozzle assembly rotates or oscillates to spray clean the pipe surface.  The arms and spray nozzle assembly interchange with other such cleaning systems depending on the shape or type of pipe and the desired cleaning technique.  The apparatus is tethered to a source of fluid under pressure and a power source both of which are located off-board the apparatus at a remote location.  An operator supervises the device's operation, controlling the speed and direction of travel of the vehicle, the speed and direction of oscillation and rotation of the cleaning system, and the fluid pressure delivered by the spray nozzles.

Title: A split power, differential aided cvt
Inventor: VAN SOLKEMA JEFF
IPC: F16H37/08
Filed: 1999-04-14
Granted: 2012-10-16
Abstract: The Split Power, Differential Aided CVT is an improvement of a standard belt type continuously variable transmission. It includes a pair of variable diameter pulleys and a belt, which provide the variable belt ratio mechanism for this transmission to continuously vary the final transmission ratio. The first variable pulley is mounted on the transmission input shaft. The final transmission ratio varies as a function of the belt ratio due to the inclusion of a differential gear set and an additional gear set.  Utilized in this application, the differential has two inputs and one output. The additional gear set connects the transmission input shaft to the differential's first input (the differential ring gear), causing the ring gear to turn in the same rotational direction as the input shaft. The first (primary) gear in the gear set is mounted on the transmission input shaft. The ratio of the rotational speed of the input shaft and primary gear to the differential ring gear is referred to as the gear ratio. The aforementioned continuously variable belt and pulley arrangement connects the transmission input shaft to the differential's second input, a shaft (also called the power transmission shaft) inserted into one of the differential side gears. The second variable pulley is mounted on this shaft. The other differential side gear and the shaft extending from it serve as the transmission output shaft.  It is the combination of the variable belt ratio with the differential and the fixed gear ratio in the aforementioned manner that achieves a variable final transmission ratio range (from max ratio to min ratio) that a standard variable belt arrangement cannot achieve, namely from positive ratios to negative ratios, including a zero ratio.

Abstract: An electronic delay circuit (10) useful for the delayed initiation of detonators illustrates several novel features that may be combined, including a novel oscillator (34), a programmable timer circuit (32) and a run control circuit (46). The oscillator (34) generates a clock signal determined by the rate of discharge of a capacitor (34a) relative to a reference voltage REF. A  second capacitor (34b) is charged to a voltage that exceeds REF, and when the first capacitor (34a) falls below REF, an internal signal is generated and the capacitors are switched, so that the first capacitor gets charged while the second is discharged. A latch (34f) produces clock pulses in response to the internal signals. The programmable timer circuit (32) includes a ripple counter (38) and a program bank (40) that loads a count in the counter upon initialization. Each stage of the counter (38) has separate inputs for set and clear signals, and the program bank (40) has a setting circuit and a clearing circuit for each counter stage. Each clearing circuit generates a signal of fixed duration and each setting circuit can generate a signal of two different durations, one of which exceeds the clear signal. During programming, the set signal of short or long duration is chosen and, in loading the counter, the longer of the set signal or the clear signal determines the state of the counter stage. The run control circuit (46) controls a gate (34h) that permits oscillator pulses to increment the counter (38), but closes gate (34h) should a temporary loss in power occur thus preventing the timer (32) from being re-initialized.

Abstract: The invention provides a safe and economical nonprescription combination of acetaminophen, aspirin and caffeine (APAP/ASA/CAF) for use in treating migraine pain and the cluster of symptoms characteristic of migraine attack, such as nausea, photophobia, phonophobia and functional disabilities. In accordance with the present invention, the u se of the APAP/ASA/CAF combination is also effective in aborting the prodrome phase of a migraine attack, prior to the onset of the migraine- associated symptoms, aborting the symptoms of migraine attack prior to the onset of severe, throbbing migraine pain, and aborting migraine pain after a migraine has fully developed. In accordance with the present invention, the efficacy of the APAP/ASA/CAF combination treatmen t in reducing and eliminating migraine pain is at a parity with the efficacy of sumatriptan, a known, but dissimilar, anti-migraine agent, used at similar dosing regimens. Use of the APAP/ASA/CAF combination composition treatment at the unit dose also advantageously reduces/obviates the need of the migraine sufferer to re-dose or re-medicate at the end of the dosing period in accordance with the present invention.

Abstract: A prosthetic heart valve (11) comprising a tubular valve body (13) and a pair of leaflets (15) which pivot, or translate and pivot, between open and closed positions. The valve body is of circular interior cross section except for a pair of diametrically opposed flat wall sections (23) which contain recesses (25) within which the pivot axes of the leaflets are located.      Arcuate edges (35) of the leaflets are irregularly shaped so that a pair of protrusions (73) extend radially outward from an otherwise generally semicircular periphery.      The protrusions (73) are strategically located so as to contact the interior surface of the valve body in the closed position at arcuately spaced apart locations which flank the centerline of the leaflet. As a result, contact in the closed position occurs at two spaced apart locations rather than at a single location, and at least a minimum gap is established at the central tip (71) of the leaflet which counteracts potential cavitation ,noise and hemolysis.
