Abstract: A speaker system to distribute sound may include a housing formed from Himalayan salt rock having a central aperture; a platform being positioned within the central aperture; a light source being mounted on the platform; a base connected to the housing; and a speaker connected to the base at an acute angle.

Abstract: Dispensing of commodities such as bulk liquids, gases, granules and powders is monitored electronically by identifying receivers of the commodities with specific codes and relating those codes to amounts dispensed by commodity dispensers. The specific apparatus includes a passive module attached to the commodity receiver and a reader linked to the commodity dispenser by radio transmitter or hard-wired. The passive module includes a planar member therein with a code thereon in form of a pattern of conductive and non-conductive areas, the particular organization of which determines the code identifying a particular commodity receiver. The reader includes: an array composed of pairs of opposed inductors for alignment with the conductive and non-conductive areas; a multiplexer for indexing the pairs of opposed inductors to determine if an area is conductive or non-conductive, and a transmitter for relaying the code to the commodity dispenser.

Abstract: An electronic dictionary having a keyboard with a plurality of character keys, a clear key and a definition key; a plurality of flip-flops each associated with one of the character keys for indicating the characters in an entered word; a counter for accumulating a count indicating the number of entered characters; a pulse generator enabled upon operation of the definition key to provide a pulse train to a further counter which disables the pulse generator upon a given count; decoder logic receiving as an input the outputs of the flip-flops and the outputs of the two counters to produce a sequence of character codes at an output as the further counter is incremented, such codes being stored in a register and applied to a conventional display to form a definition of an entered word and the clear key then being operated to reset the circuitry and blank the display.
