An uninterruptible power supply unit for coupling between an adapter with an adapter connector and an electronic device in accordance with one embodiment of the present invention includes a self-contained housing, a backup power supply, and an output switch system. The self-contained housing has an input port for coupling with the adapter connector from the adapter and an output connector extending from the housing for coupling with the electronic device. The backup power supply is located in the housing and provides the backup power. The output switch system is also located in the housing. The output switch system is coupled between the output connector and the input port and the backup power supply and couples the backup power from the backup power supply to the electronic device when incoming power from the adapter fails. The uninterruptible power supply unit may also include a polarity switch moveable between a positive position coupling one lead of the output connector to the positive terminal for the backup power supply and a negative position coupling the one lead of the output connector to the negative terminal for the backup power supply.

Uninterruptible power supply unit

An electronic learning system that utilizes a plurality of coded cards on which sensory-information representations are provided to present pictorial-symbol information and/or language-symbol information, in conjunction with a housing that contains card slots in combination with a visually and functionally distinctive button associated with each individual card slot and a button associated in an equal manner to all card slots, wherein a card may be inserted in each of the card slots. The operator can cause the system to generate unique audible information associated with the sensory-information representation provided on any selected card by pressing the visually and functionally distinctive button associated with the card slot in which the card is inserted. The operator can also cause the system to generate, automatically and sequentially, unique audible information associated with the sensory-information representation provided on each inserted card and, depending on the type of cards installed, perform secondary functions as the individual cards are being accessed, such as, mathematical computations, pattern recognition, and spelling accuracy by pressing the visually and functionally distinctive button associated in an equal manner with all card slots, after which automatic tertiary functions take place such as the accuracy of the result of mathematical computations are accessed and an audible message is generated; an audible message equivalent to the combination of the installed cards is generated; and the accuracy of the spelling of words formed by individual cards is determined and an audible message is generated.

Card type of electronic learning aid/teaching apparatus

A self-contained remote control unit for use on electronic equipment processing on audio output such as home entertainment equipment (i.e. a television receiver, whether black and white or color, an AM radio, an FM radio, an AM/FM radio, or an audio magnetic tape player) comprises an externally mounted remote control receiver which connects to the home entertainment equipment through the earphone connector of said equipment and thereby disables the speakers of said equipment. The remote control receiver unit includes its own speaker which replaces the disabled internal speaker of the equipment to be controlled, a programmable audio power amplifier for driving its speaker, and an on/off triac which supplies AC power to the equipment to be controlled when said equipment's AC power cable is connected to an AC receptacle on the receiver. A battery-operated, hand-held, hand-operated remote control transmitter is used to send wireless information to the remote control receiver. The remote control transmitter unit includes a keyboard, a remote control encoder, and an output circuit.
