Abstract: A hand held device (10) for measuring automatically the Hormonal Quotient and correlated hormonal status of an individual, providing a measure of index finger for ring finger. The device (10) includes a base (30) upon which a concentrically arranged disc (40) is rotatable mounted by a central fastener (11). The base (30) carries a ruler face (32), a first finger-length logarithm scale (36), a Hormonal Quotient logarithm scale (38) and an arrow indicator of the gonadal hormone exposure index (39). The disc (40) carries a second finger-length logarithm scale (42) and the Hormonal Quotient arrow (44). When scales (42) and (36) are properly aligned the Hormonal Quotient arrow (44) inserts automatically into the resulting Hormonal Quotient in the Hormonal Quotient scale (38) and the correlated gonadal hormone exposure (39).

Abstract: An aroma visual message carrier is shaped into a card device for carrying multisensory messages to deliver two interchangeable images with a scent releasing mechanism linked to the very act of image change by a recipient. The carrier comprises an image changing frame including a still image member with a first image printed on it and a sliding image member with a second image print partially interlaced with the still image member so that a manual sliding action of the still image member brings the two images interchangeably fade in and out laterally through each other. The still image member has a deposit of scent material formed rearward of its visual side.

Abstract: Arithmetic Measurement System quantifies arithmetic operations just by measurement and without arithmetic calculation or even counting. Playing cards may be annotated with size-coded marks or card tags to represent face value. For example, a tag representing a face value 5 is half the size of one representing a value 10 using a linear tag scale, or about 7/10th the size using a log10 tag scale. Users align linear tags in a contiguous row to add values or overlap tags to subtract values. Users align logarithmic tags in a row to multiply values or overlap tags to divide values. Integrated and separate measures with corresponding linear or logarithmic tag-scales quantify a total value of aggregate or net tag row size. Product developers may use the Arithmetic Measurement System of tags and measures to provide novel educational math manipulatives and playing card games for players unskilled in arithmetic.

Abstract: The present invention consists of a numeric teaching device having a plurality of spinning wheels mounted on an axle and a decimal point indicator appearing between two groups of spinning wheels, with each spinning wheel containing the digits 0 through 9 printed on the outer annular surface of the spinning wheel in columnar form so that when the wheels are spun, different numeric formulations may be created by the user of the device. The axle containing the spinning wheels is supported by three dowel rods secured to a wood base, with each dowel rod further having a cradle at its upper end for communicating with the axle. The device is especially important in teaching numeric place values, numeration or the formation of numbers, and the rounding of numbers.

Abstract: The present invention discloses a method and tools for teaching rapid and accurate decoding and encoding words. In decoding (reading), the invention delineates the concept of sound units (a combination of blendable letter sounds) and their use to accurately decode words systematically and efficiently. In encoding writing or making words), the invention utilize a combination of wheels to help children with limited motor skills to easily and accurately encode thousands of words and word like combinations so as to learn and familiarize themselves with words and their structures. The same wheels can also be used to create math wheels and sorting wheels that can train children's early math skills in adding, deducting, multiplication, subdivision, and other important abilities.

Abstract: The present invention comprises an electronic learning game that provides a plurality of pedagogical and instructional modalities which combine strong kinesthetic, auditory, and visual stimulation to assist a child to learn basic arithmetical concepts. The inventive game utilizes a combination of voice statements, rhythmic music, a visual display, and manual inputs from number dials and a response switch to achieve multi-modal learning or arithmetic concepts. The ergonometric size and structure of the present invention promotes a strong kinesthetic learning modality.

Abstract: An apparatus comprises a first plurality of first numerical sequences, each numeral within each first numerical sequence being identified by a common indicia and each of the plurality of first numerical sequences having a different indicia; a second numerical sequence of numerals; and a selector which is relatively movable with respect to the first and second numerical sequences for selecting one numeral of the second sequence of numerals. The selector has third numerical sequence wherein each numeral of the third sequence has an indicia which corresponds to the common and different indicia of the first numerical sequence. The common and different indicia is color or pattern selective. In the method, the numeral of the first numerical sequence is a mathematical function of the numerals of the second and third numerical sequences.

Abstract: A device for recording a series of exercises to be followed over a period of days and for indicating the order in which the exercises are to be performed on a given day. When the exercises are recorded in pencil, they may be erased and rewritten when the exercise regimen is changed by the exerciser. The device includes three flat, circular plates that are rotatable independently of one another about a common pivot point. A plurality of radially extending lines are disposed on a base plate and one exercise is written on each line. Exercises to be performed in one day are grouped together on contiguous radial lines. An intermediate plate has a window formed in it that exposes to view a group of the radial lines when the window is in registration with the group, and a pointer plate includes a pointer that points at an exercise written on a particular line of the group that is exposed to view.

Abstract: A puzzle comprises a plurality of puzzle elements held together along a common axis. Each of the puzzle elements includes first and second faces and a peripheral edge. A series of discrete symbols are formed along the peripheral edge of each element. Preferably, the puzzle elements are magnetic wheels held together by magnetic forces. The magnetic wheels have a series of protuberances on one face which are adapted to register with a series of cavities on an opposing face of an adjacent magnetic wheel. The magnetic wheels are rotated relative to each through a series of click-stops which correspond to discrete positions of the magnetic wheels. A solution is achieved when all of the symbols on each of the magnetic wheels are properly aligned.

Abstract: A puzzle-type game comprises at least five manipulatable members, for example of square or circular cross-section, each formed at one end with fingers, and at the opposite end with a circular recess, such that a plurality of the members may be assembled by the player according to any desired sequence, and to be rotated to any desired angular position with respect to each other. Each member carries on its outer faces indicia representing one element of a valid multi-element relationship produced only when the indicia of all the members are aligned according to a predetermined sequence and a predetermined angular position. In one described example, the indicia represent arithmetical equations, and in other described examples they represent the letters of the alphabet, and a maze.
