Abstract: A content navigation method that may be used with a storage device that holds multiple content objects includes a controller, at least one search switch and at least one control switch. Each of the content objects has a corresponding name which includes at least one character from an alphabet. The controller determines a set of names of the stored content that corresponds to the activation of the search switch, displays at least one name the set of names and, responsive to the control switch, selects the content object corresponding to the displayed name. The search switches may include multiple search switches, each associated with a predetermined set of letters from the alphabet. Alternatively, each switch may have an corresponding display and may be associated with a dynamically determined set of letters based on their frequency of occurrence in the names.

Abstract: A twisting ring control for a compact speaker is rotatably mounted on a speaker encircling the speaker baffle. When the ring is rotated in one direction, the ring causes the speaker to be switched off, and when the ring is rotated in the opposite direction, the ring causes the speaker to be switched on. A volume control can be integrated into the same mechanism, and arranged such that, after the speaker is switched on, when the ring is rotated in one direction the volume is increased and when the ring is rotated in the opposite direction the volume is decreased.

Abstract: A hand held electronic music reference machine includes a platform having a keyboard and a display for displaying text. A database removably or permanently mounted to the platform has a first memory portion storing, for each of a multiplicity of songs, selected lyrics and identification information including a title. The database has a second memory portion storing a segment from each of the songs. A user actuated selection component is operatively connected to the first memory portion of the database and to the display for permitting operator selection of a song from a list of song titles shown on the display and inducing display of the lyrics stored in the first memory portion for the selected song. In addition, a user actuated audio production element provided on the platform is operatively coupled to selection component and the database for enabling an audible reproduction of the segment stored in the second memory portion for the selected song.
