Abstract: A recording device that is coupled to a book. The recording device records, saves and plays back a plurality of discrete messages. An archival control disables and enables the device, thus permitting the user to ensure that no new messages will be accidentally recorded over existing saved messages.

Abstract: An ultrasonic broadband frequency transducer pest repulsion system comprises: a variable frequency generator; at least one ultrasonic frequency amplifier coupled to the variable frequency generator; and a transducer unit coupled to the ultrasonic frequency amplifier. The transducer unit comprises: a first transducer tuned at a first frequency located between a lower frequency and an upper frequency; a second transducer tuned at a second frequency located between the first frequency and the upper frequency, and a third transducer tuned at a third frequency located between the second frequency and the upper frequency.

Abstract: An environmental test chamber fast cool down system. The environmental test chamber fast cool down system, comprises: an environmental test chamber evaporator, a cascade condenser coupled to the environmental test chamber evaporator, a sub-cooled primary stage loop coupled to the cascade condenser, a sub-cooled secondary stage loop coupled to the cascade condenser, and a thermal storage unit coupled to the sub-cooled primary stage loop and to the sub-cooled secondary stage loop.

Abstract: A loop-current regulator for protecting terminal telephone equipment coupled to telephone lines from high telephone line loop-current. The loop-current regulator has a current regulator for protecting the terminal telephone equipment from excess power generated by current signals which pass through the telephone lines to the terminal telephone equipment. A signal network circuit is coupled to the current regulator for providing an alternating current (AC) path for AC signals to pass by the current regulator while minimizing attenuation of the AC signals. A bridge rectifier circuit is coupled to the current regulator, the signal network circuit, and the telephone lines for allowing the current signals to pass in only a single direction through the current regulator and the signal network circuit regardless of the polarity of the telephone lines.

Abstract: A truck bed extension is provided for extending the useful length of a pickup truck bed. The truck bed extension includes a pair of transversely spaced sidewalls interconnected by a spacing member, with each sidewall coupled to a downwardly extending mount having an inwardly oriented pin, whereby the pins are substantially opposed and collinear. The pins are positioned for receipt into openings in the tailgate housing latches. When the truck bed extension is lowered, the pins are received into and releasably coupled with the latches. Brackets are preferably provided adjacent the forward margins of the sidewalls and oriented outwardly to receive inwardly extending posts extending inwardly from the bed walls.

Abstract: A method of playing a video poker game which allows the player to pick the cards to form his or her poker hand. All the playing cards are placed lying face down. The player picks and turns over a predetermined number (i.e. five) of the playing cards to form an initial poker hand. The player then determines which of the selected cards to hold. If one or more of the selected playing cards are discarded, the player selects and turns over replacement playing card(s) from the remainder of the playing cards which are lying face down.

Abstract: An emissions reduction system comprising an emission gas inlet for receiving emissions-containing gas, and an emissions reducing device for reducing emissions contained in the emissions-containing gas. The emissions reducing device is coupled at a first end thereof to the emission gas inlet and an emission gas outlet is coupled at a second end of the emissions reducing device for releasing emissions-reduced gas. The emissions reducing device comprises: a torturous fluid channel, lava material displaced within the torturous fluid channel wherein the lava material is located within a set of self contained containers within the emissions reducing device.

Abstract: A container for storing shoes having cleats/spikes uses a shoe bag for storing the shoes having one of cleats or spikes. A protective flap is coupled to the shoe bag and is used to protect a surface of an object from being damaged by a bottom portion of the shoes when the shoes are placed on top of the protective flap when an individual is putting on the shoes.
