A system and method for teaching music both visually and tactilely. In one embodiment, the invention comprises blocks shaped to resemble musical symbols used to compose music, including time signatures, notes, rests, and dots. Each of the blocks are relative in thickness such that for a given time signature, the correct rhythm for a given measure can be determined by laying one or more of the notes, rests and dots one over the other to see if their combined thickness is equal to that of a preselected time signature. The thickness of the block shaped to resemble the time signature is such that it only allows the correct number of blocks shaped as notes, rests or dots to be of equal thickness to thereby determine the correct rhythm. In addition, the correct rhythm can be determined by simply reading the shaped blocks as one would read music. The use of the shaped blocks having relative thicknesses allows a student to learn rhythm by trial and error and does not necessarily require that the student understand complex music theory. In addition, the blocks can be used by the student when clapping the correct rhythms. Other musical notation can be represented by blocks as well such as bar lines and slurs.

A representation of a codeword is decoded by applying a first decoder of the codeword to the representation of the codeword. If applying the first decoder fails to decode the representation of the codeword then a second decoder of the codeword is applied to the representation of the codeword. Preferably, applying the first decoder consumes less power and is faster than applying the second decoder. Data are ported by encoding the data as a codeword, exporting the codeword to a corrupting medium, importing a representation of the codeword, and applying a first decoder to the representation of the codeword. If applying the first decoder fails to decode the representation of the codeword then a second decoder of the codeword is applied to the representation of the codeword.

A method for producing polyphenylene sulfide (PPS) polymer, including polymerizing reactants in a reaction mixture in a vessel to form PPS polymer in the vessel, measuring values of operating variables of the vessel and / or PPS process, and determining the amount of quench fluid to add to the vessel based on the values of the operating variables. The technique may rely on the vapor liquid equilibrium (VLE) of the mixture to calculate the concentration of water existing in the reactor prior to quench, and accounts for the effectiveness of the upstream dehydration process and in the amount of water produced during the polymerization. The technique is a striking improvement over the trial-and-error estimation of the amount of quench water based on human operating experience, and avoids direct measurements of the existing water concentration in the reactor. The result is improved control of PPS particle size and other properties.

The present invention relates to a device and method for displaying various menus of a microwave oven onto one screen. In the present invention, the various menus can be displayed onto one screen by using a tree structure or window structure. To this end, display control data are stored such that the various menus can be displayed in the form of the tree structure or display window. These display control data are stored in a separately provided storage device. According to the present invention constructed as such, since the user can confirm the various functions of the microwave oven on the same screen at one time, there is an advantage in that trials and errors made when using the microwave oven can be minimized. In addition, since all the functions can be confirmed simultaneously, there are further advantages in that the time required for learning how to use the microwave oven is reduced and function selection can be conveniently made.

The present invention provides a means for guiding a medical device within the body to approach a target destination. The system and method provide a means for determining a predicted length and orientation, navigating the device to an intermediate point less than the predicted length, determining an error between the projected destination and actual target destination, and successively updating a predicted value of a control variable to yield an orientation within a predetermined distance error before advancing the device the remaining distance to the destination. This provides a physician with the capability of verifying the device will be accurately guided to the target destination without trial and error. A method is also provided for intuitive navigation to targets with limited trial and error based on user-applied device orientation adjustments, where the user chooses the magnitude of the adjustments and the system determines the adjustment direction.

A robot-guided system to assist orthopaedic surgeons in performing orthopaedic surgical procedures on pre-positioned inserts, including for the fixation of bone fractures, and especially for use in long bone distal intramedullary locking procedures. The system provides a mechanical guide for drilling the holes for distal screws in intramedullary nailing surgery. The drill guide is automatically positioned by the robot relative to the distal locking nail holes, using data derived from only a small number of X-ray fluoroscopic images. The system allows the performance of the locking procedure without trial and error, thus enabling the procedure to be successfully performed by less experienced surgeons, reduces exposure of patient and operating room personnel to radiation, shortens the intra-operative time, and thus reduces post-operative complications.

A computer system, method and computer program product for automatically converting, through automating-test-automation software, a manual test case representation (in a natural language), for testing a target software, into a machine-readable test case representation. In preferred embodiments, the machine-readable test case is in the form of a keyword-based test case that is made from action-target-data tuples. The automation-test-software uses a methodical process of trial-and-error to resolve ambiguities that are generally present (and generally resolvable by humans) in the manual test case representation.
