Abstract: A flexible or roll-up electronic keyboard is provided for use with electronic devices. The keyboard is formed with a plurality of section of flexible plastic materials and embodies a dual-walled bottom which includes a network of support members which can be inflatable to provide a rigidity to the structure of the keyboard sufficient to prevent false signals. At least one separately inflatable accordion-pleated wedge means is also provided to enable variable adjustment of the plane or planes of the keyboard relative to the hands of its operator, sufficient to reduce the risk of nerve disorders such as carpal tunnel syndrome in the operator.

Abstract: A composition, which is suitable for containment in a water soluble bag as a liquid or a gel, contains a hazardous product and an electrolyte and water and other additives. Typical hazardous products include agrochemicals such as pesticides, plant growth regulators and plant nutrients. Optionally the composition contains a thickener, a solvent or a dispersant. The water soluble bags used as containerization systems for these compositions may be made of polyvinylalcohol.

Abstract: An amplifier for amplifying RF signals comprises a transistor, a first impedance, an impedance transformer, and a tuned resonant circuit. The amplifier receives the RF signals via a signal terminal of the transistor, wherein the RF signals are amplified by the transistor, the tuned circuit, the first impedance, and the impedance transformer. The degree of amplification is based on the impedance ratio between the impedance transformer and the first impedance, wherein the first impedance may be an output impedance matching transformer.

Abstract: An audio arrangement includes a thin speaker/transducer positioned within a portable housing wherein the speaker cavity is dimensioned to move the resonant frequency of the speaker/housing combination up to approximately the free-air cutoff frequency of the speaker/tranducer. The resulting response then falls off at about 6 db/octave below that point. An amplifier having gain increasing at 6 db/octave is placed in the signal input path for creating an essentially flat frequency response in the normally desired audio range.

Abstract: A power inverter for an electroluminescent device is disclosed which enables the electroluminescent device to be powered from a low voltage DC power source. Switching transistors convert the low voltage DC power to low voltage AC power which is subsequently increased and coupled to a resonant circuit including the electroluminescent device. Current in the resonant circuit is sampled, referenced to half the low voltage DC power, and coupled back in phase to an amplifier and switching transistors to create an oscillator which oscillates at a frequency determined by the resonant circuit.

Abstract: Improved radio transmitter modulation control circuitry is described which significantly increases the average power of the modulating signal, resulting in enhanced audio signal quality since the signal-to-noise ratio is likewise increased. The inventive modulation control circuitry includes a microphone 110, audio amplifier 120, splatter filter 130, modulator 150, potentiometer 140, oscillator and transmitter 180, and antenna 190. The audio amplifier 120 further includes an operational amplifier 160 having an input resistor 162 coupled via capacitor 168 to microphone 110, a phase-lag filter 170 coupled to the output of the operational amplifier 160, and a feedback resistor 161 coupled between the filter 170 and the input resistor 162. When driven into amplitude limiting, the phase and amplitude of harmonic signals from the operational amplifier 160 are altered by phase-lag filter 170 to produce a waveform similar to that shown in FIG. 2.

Abstract: The present apparatus suspends a book above the reader from an overhead support. It includes a suspension line hanging down from two support attachments above. Suspended from the middle of the line is an assembly of a book tie rod which holds the book along its spine and a suspension bar extending from side to side behind the cover of the book. An apertured control tube couples the book tie rod to the suspension bar. Page retainers are carried by the suspension bar to engage the open pages of the book. A pitch line extends down to the suspension bar at one side of the book from a pitch bar which engages the opposite sides of the hang line a short distance above the suspension bar and tie rod.
