Abstract: A new "cold-loading" technique for filling the amorphous central cavity of paucilamellar lipid vesicles with a water immis-cible material has been developed. Preformed, substantially aqueous filled paucilamellar lipid vesicles are mixed with the water immiscible material to be encapsulated under intermediate mixing conditions, thereby replacing the aqueous solution with the water-immiscible solution. The "cold-loading" technique is particulary useful for encapsulation of volatiles and heat labile mate-rials.

Abstract: Methods and apparatus for determining whether an encoder of a borehole tool is jammed are disclosed.  The borehole tool has a motor with a drive shaft which is coupled to and drives an encoder, a position sensor coupled to the motor for sensing the position of the motor, and a microprocessor coupled to the position sensor and to the motor in a feedback loop, with the microprocessor controlling the movement of the motor based on the sensed position of the motor and the desired position of the motor.  The method for determining jamming includes: determining, at a first plurality of times, positions of the motor from the position sensor; determining position errors of the motor from the positions of the motor and desired positions of the motor as determined by the microprocessor; and determining whether the encoder is jammed based on whether the position error exceeds a threshold value.  In determining jamming, the microprocessor can also determine the rotational velocity of the motor, and account is taken of whether the motor velocity exceeds a threshold velocity at a time when the position error exceeds its threshold value.

Granted: 1998-12-08
Abstract: An IDCT method decimates a 2-D IDCT into two 1-D IDCT operations and then operates separately on the even and odd pixel input words.   In a common processing step, selected input values are passed directly to output adders and subtractors, while others are multiplied by constant, scaled cosine values. In a pre-common processing step, the lowest-order odd input word is pre-multiplied by ~2, and the odd input words are summed pairwise before processing in a common processing step.  In a post-common processing step, intermediate values corresponding to the processed odd  input  words  are  multiplied  by  predetermined coefficients  to  form  odd  resultant  values.    After calculation of the even and odd resultant values,  the high-order and low-order outputs are formed by simple subtraction/addition, respectively, of the odd resultant values from/with the even resultant values.   The input values are preferably scaled upward by a factor of ~2. Selected bits of some intermediate resulting data words are optionally adjusted by forcing these bits to either "1"  or  "0".     The IDCT system includes  a pre-common processing circuit (PREC), a common processing circuit (CBLK), and a post-common processing circuit (POSTC), which perform the necessary operations in the respective steps.  The system also includes a controller (CNTL) to generate signals to control the loading of system latches and, preferably, to time-multiplex the application of the even and odd input words to latches in the pre-common circuit.

Title: System and method for automatically selecting among a plurality of input modes
Inventor: BAKER BRUCE R
IPC: G06F3/00
Filed: 1991-09-27
Granted: 2001-05-29
Abstract: A continuous input system allows a system operator to continuously input a plu-rality of polysemous icon symbols to access stored (l3, l4) morphemes, words, phrases, or sentences corresponding to an icon se-quence. The system, with automatic mode selection for the input system, containing a plurality of character and symbol keys (4), allows for automatically selecting (4, 5) of the icon (12, 17, 22) mode, a character or word prediction mode (14, 15, 23); and even a subsequent suffix mode, to allow a user to enter morphemes, words, phrases, or sen-tences sequentially. Further, by utilizing the character and word prediction (l4, 15, 23) modes, including the suffix (27, 32) mode; words; phrases or sentences corresponding to non-accessible icon sequences can beau-tomatically activated without having to man-ually switch out of the icon mode or select the character and word prediction mode.    Such automatic icon, word prediction, char-acter and suffix mode selecting, thereby al-lows continuous text (16) or speech (18) gen-eration with a minimal number of input key (4) activations necessary for a system opera-tor.

Abstract: An improved mechanism for converting handwritten input data into text and commands in a computer system is provided. An unintended results detection component is used after the handwritten data has been converted to text and commands. The unintended results detection component determines when the converted text and commands were likely unintended by the computer user.

Abstract: The present invention is directed to a papermakers fabric which provides for usage of high aspect ratio yarns as structured weave components. The fabric comprises a system of flat monofilament machine direction yarns (hereinafter MD yarns) which are woven in a selected weave construction which provides stability to the fabric. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. the lower MD yarns may weave in an inverted image of the upper MD yarns to provide floats on the bottom fabric surface or may weave with a different repeat to provide a different surface on the bottom of the fabric.             At least the upper MD yarns are flat monofilament yarns woven contiguous with each other to reduce the permeability of the fabric and to lock in the machine direction alignment of the stacking pairs of MD yarns. In the preferred embodiment, the same type and size yarns are used throughout the machine direction yarn system and both the top and the bottom MD yarns weave contiguously with adjacent top and bottom MD yarns, respectively. The stacked, contiguous woven machine direction system provides stability and permits the MD yarns to have a relatively high aspect ratio, cross-sectional width to height, of greater than 3:1.
