A method and apparatus for storing and retrieving information to and from a memory of a hand-held audio database device. The audio database device includes a graphics display provided on a hand-held housing for displaying graphical information. A microphone and a speaker are provided on the housing to receive and broadcast audio information from and to a user, respectively. The audio database device includes a memory configured to store graphical icons and to support a hierarchical memory structure comprising categories, wherein the icons graphically represent the categories. A user-actuated navigation control is provided on the housing and permits a user to navigate the categories in the hierarchical memory structure and to select a desired category. A processor is coupled to the memory, the display, and the navigation control and effects displaying of one of the icons on the display when the user is navigating a corresponding one of the categories, and storing of the audio information in the desired category of the memory.

A voice recognition interface apparatus and method for interacting with a programmable timekeeping device is disclosed. The voice recognition interface includes a display for displaying time, alarm, calendar, and other information, and also includes a microphone and a speaker for facilitating verbal communication between a user and the programmable timekeeping device. A number of illuminatable annunciators are provided on the display for visually communicating prompts to the user. Programming, querying, and other interactive operations are facilitated through use of the voice recognition interface generally by producing a visual prompt to invoke a particular verbal input from the user, receiving the verbal input by use of the microphone, validating the verbal input against a pre-established recognition word library, verbally confirming the verbal input by broadcasting over a speaker pre-synthesized words and phrases retrieved from a message word library, and displaying or otherwise broadcasting information associated with the particular programming, querying, or other interactive operation. The voice recognition interface includes a logic controller that controls and cooperates with a memory, a voice recognition device, a display, and a clock circuit to provide an intuitive voice-driven programming and querying interface for interacting with a programmable timekeeping device. Manually actuatable control switches are also provided for enhancing programming and querying operations. Advanced features include a personal message recording and playback capability, multiple programmable alarms for activating personalized alarm messages, and user-modifiable verbal prompts for personalizing the voice recognition interface dialogue.

An as-fired alumina substrate for a hybrid microcircuit formed of GaAs dies operating at gigahertz frequencies has a large number of about 0.013' diameter via holes drilled on the surface thereof by use of a laser. A metal filling in each via hole is formed with about 85% sintered tungsten and 15% copper reflowed into the pores thereof to provide a composition that has a thermal coefficient of expansion that substantially matches that of the GaAs dies and the alumina substrate and also provides for hermetically sealing the via holes. The alumina substrate is further provided with a ground plane by which it is mounted on a metal block serving as a heat sink. The high frequency GaAs dies mounted on the via holes use the metal fillings therein to carry their internally generated heat to the heat sink and to provide low inductance ground paths for the microcircuit. A process for placing the metal filling in the via holes makes use of a stencil having the same large number of via holes thereon as the alumina substrate for first squeegeeing a tungsten paste with a predetermined amount of binder into the via holes of the substrate. After the tungsten is sintered, the stencil is then used to squeegee a copper paste on the top of the sintered tungsten in the via holes. The copper in the paste is then reflowed into the pores of the sintered tungsten.
