Abstract: A pill splitter splits a pill in quarters along a major axis and a minor axis The pill splitter has a lower body, and an upper body, integrally affixed to the lower body. A rotating bed receptacle is rotatingly affixed in the pill splitter, and contains a bed substantially conforming to the pill shape. A membrane, disposed below the bed, contains a cruciate cutout into which are formed a major axis slit and a minor axis slit. A long, thin cutting blade is disposed below and in proximity to the bed receptacle. In use the, receptacle is rotated to a position so that the cutting blade is disposed beneath the one axis slit and beneath the corresponding axis of the pill. A blow struck to a plunger aligned with the blade by plunger slots and guides cuts the pill along the chosen axis.

Abstract: A signal isolation system includes an aeroisolator to couple output signals to an electronic device. The aeroisolator is made from two commercial miniature earphones, each having a ferro-magnetic diaphragm activated by a voice coil in proximity to a permanent magnet. The diaphragm is removed from one of the earphones, and the two earphones are then disposed in proximity to each other, with the diaphragm in proximity to the voice coil of each.

Abstract: A quartering pill splitter includes a bed having a recess formed within, the recess having a cross section which substantially conforms to the pill shape. A thin, cruciate cutting blade assembly is disposed below the pill bed, so that the pill, when inserted into the recess, rests on the cutting edges of the cruciate cutting blade assembly. A plunger, containing an upper compression member is moveable with respect to the cutting blade assembly and is forceably engaged against the pill disposed in the bed recess when the user strikes the cap of the plunger, thus cutting the pill into quarters in a single stroke. The cruciate cutting blade assembly contains a first blade and a second blade at a right angle relative to the first blade, and which is offset from the first blade a distance equal to the thickness of the first blade.

Abstract: A family of pill splitters is formed from a standard, substantially cylindrical lower body which contains a distinct bed for each one of a number of different complex pill shapes, and an upper body, integrally affixed to the lower body, which contains a pair of linear plunger guides slots. Each bed contains a recess having a cross section which substantially conforms to the pill shape, and the bed thickness is proportional to the thickness of the pill to be split. A long, thin cutting blade is affixed in proximity to the bed, and a bed support is formed in the lower body. A plunger with plunger guides slidingly engages the plunger guide slots. Each bed contains alignment tabs which engage the plunger guide slots to align the bed relative to the cutting blade.

Abstract: A dyslexia detection system displays a test word, either alone, or within a sentence. The test subject is asked to pronounce the test word, and to write it on a handwriting input device, such as a tablet. The system analyzes the spoken words, comparing them to sound records in a library of properly pronounced phonemes which make up the test word. The system also analyzes the characters written by the subject, and detects whether any of the characters correspond to a member of a distorted character set containing distortions commonly produced by dyslexics. A summary of errors in pronunciation shows errors in pronunciation as mispronounced phonemes, and errors in writing are displayed as erroneously written characters.

Abstract: A pill splitter for use with pills of complex shapes has a bed which substantially conforms to one-half of the pill. The bed is affixed within the cylindrical lower body of the splitter, into which a blade is affixed. A clearance slot allows the blade to be exposed within the bed at a height such that the pill, when placed in the bed, just touches the blade. A plunger containing guides is inserted in the cylindrical upper body, so that the plunger lies on the upper surface of the pill, along a line directly above the blade. A sharp blow to the cap of the plunger drives the pill onto the blade below, splitting the pill.

Abstract: A method for incorporating dyslexia detection into existing handwriting pattern recognition software includes a database of distorted characters along with the database of legitimate characters with which the handwriting samples are compared. The distorted characters are those recognized as typical of those produced by dyslexic persons. The system used may be a personal computer, a personal digital assistant, or an Internet system. Whatever system is used, a means of freehand drawing must be included, such as a stylus with pressure sensitive drawing area, a drawing tablet, or pen-pad-type device. A character is first presented to the student for reproduction. The student then draws a character on the pad, attempting to reproduce the character. The system software detects a correspondence between the character input and the legitimate characters, when occurring.
