Abstract: The present invention is generally directed to a case for portable electronic devices. The case includes a body having a receiving portion for releasably receiving a portable electronic device. The case may also include at least one user operable input means for detecting user selection of at least one parameter, and may include a communication module for providing a communication channel between the case and the portable electronic device. A signal determined from a user selection of the at least one parameter is communicable from the case to the portable electronic device across the communication channel.

Abstract: A power adapter is provided that includes a base adapter configured to perform power conversion to supply power requirements of an electronic device from a power source. The power adapter converts the power signal from the power source into power signal compatible with the first electronic device. Input and output connectors provide coupling to the power source and electronic device, respectively. An accessory adapter can be provided and can be configured to be removably coupleable to the base adapter for modular operation. The accessory adapter can be configured to provide another power signal to power a second electronic device. Multiple accessory adapters can be added to provide power requirements for multiple devices. Security keys can be used to authenticate the power supply for security and verification purposes.

Abstract: A multiple outlet power product, includes a main body having a first power connector, a power cord having first and second ends, the first end attached to the main body and electrically connected to the first power connector, a power plug attached to the second end of the power cord and configured to receive power from a power source, and a circuit breaker disposed in the main body. In one embodiment, the first power connector is shaped so as to directly interface to an AC power adaptor without the need for a cord between the first power connector and the AC power adaptor. The power cord can further include a connection adaptor, the connection adaptor having a first end configured to mate to the first power connector and a second end configured to mate to a power adaptor.

Abstract: An apparatus and method provides control over the relative level of audio and background sound for an audio device such as a headset or headphones. An input sound transducer can be provided and configured to convert ambient acoustical pressure into an electrical background signal representing the background sound. Noise cancellation circuitry create a cancellation signal that is the inverse of the electrical background signal. A summing component is coupled to the noise cancellation component and combines the cancellation signal with an audio signal representing audio program content and provides the combined electrical signal to an output sound transducer. A controller is coupled to the noise cancellation component and is configured to control the level of a cancellation signal relative to the audio signal, thereby controlling the mix of cancellation signal and audio signal reaching the output sound transducer.
