Abstract: A disk holding device for packaging hard drive disks includes a base and a cover. The base includes a central portion and at least one locking surface near an end of the base. The cover includes a latch arm near one end of the cover. The latch arm has a locking tab that transversely protrudes from the latch arm in a direction from the central portion of the base toward the end of the base. A space extends between the cover and the base for receiving a cassette portion when the locking tab is received against the at least one locking surface.

Abstract: Methods and apparatus are described for enabling a user using a communication device, such as a cell phone, to make and receive calls in a hands-free mode and utilize an existing audio system, such as a radio, to output audio received from the other party, i.e., the calling or called party. An accessory containing an RF transmitter and a microphone, among other components, is attached mechanically to a communication device, for example, using a clip. There is no electrical or digital connection between the accessory and the communication device. The accessory has an internal microphone which is positioned close to the speaker of the communication device to detect sounds waves emanating from the speaker. The sound waves are converted to an RF signal and transmitted to a radio at a particular radio frequency channel thereby allowing the user to hear the other party's voice over the radio speakers.
