Abstract: Systems and methods for classifying structured vocabulary where an input is received that includes one or more terms. The one or more terms relate to an area of technology. Each one or more terms are identified and extracted from the input. The results of the extraction may be reviewed, and manually modified if appropriate. Each extracted one or more terms are classified where the classification associates a classified term to each extracted one or more terms. Each classified term is related to the area of technology. The results of the classification may be reviewed, and manually modified if appropriate. A result output is generated containing each one or more terms and the associated classified terms.

Abstract: A system for summoning a service industry worker using pulsed width modulation for remote signalling having a number of signalling switches, each connected to a transmitter. When a switch is activated, the corresponding transmitter transmits an RF carrier modulated by a lower frequency tone, turning the tone on and off in a pattern determined by a unique code assigned to the switch. A central receiver filters the signal from the transmitter and converts the tone pattern to a binary output to a computer. The computer instructs a display unit to turn on a light corresponding to the switch by sending its number in a serial bit stream of all lights that should be on. The bit stream is interpreted by circuits in the display unit using a clock signal. Upon the clock signal, the bit is sent to the appropriate register, which is used to turn on the correct light.

Abstract: A cleaning device (10) for bath tubs, shower enclosures, swimming pools, and the like, comprises a more rigid support block (12) attached in a cavity (40) formed in a sponge block (14). A support-block bottom surface (22) is substantially flat and is substantially parallel to a substantially flat sponge bottom outer surface (36). A support-block sidewall surface (24) extends upwardly from said support block bottom surface when said support block bottom surface is horizontal but includes an inwardly beveled transition portion (30). A bottom edge area (38) of a sponge block outer surface (32) is spaced substantially further from the support block than other portions of the sponge outer surface. There is a dimple (50) in the sponge bottom outer surface positioned below the cavity.

Abstract: A cleaning device (10) for bathtubs, shower enclosures, and the like comprises a sponge block having an outer surface which substantially defines a rectangular polyhedron in shape and which has a cavity (34) cut into a top surface thereof which is similarly shaped and oriented correspondingly as is the outer surface of the sponge block. A rigid support block (14), having an outer surface with length and breadth dimensions which are approximately the same as the size and shape of the length and breadth dimensions of a cavity surface, is adhered in the cavity by a chemical (cleaning), detergent, and water resistant, elastic, adhesive (18) and an elongated handle (16) is attached to a top surface of the support block. The sponge block is constructed of reticulated sponge material and distances between side, end, and bottom surfaces of the support block and the sponge outer surface fall in a range from 1/2 inch to 2.5 inches.

Abstract: A memory system is shown in which communication to and from memory cells is effected by optical beams. Memory cells are shown employing elements with negative resistance and operating in either of two stable modes. Other memory cells are shown employing subharmonic oscillators operating in either of two phase relationships. The memory cells and systems permit extremely fast operation.
