Dual purpose, weather resistant data terminal keyboard assembly including audio porting

Abstract: An improved data terminal utilizing tactile switch assemblies with specialized sound apertures provide reduced panel space requirements and indirect sound paths for miniature electronic apparatus. A maximum number of switches can be accommodated on the instrument panel with no separate speaker/microphone grille required. Non-aligned sound apertures provide maximal weather protection for speaker and microphone mounted behind the switch assembly panel. The switch assembly design seals off the remainder of the unit from weather or dust damage.

Method for forming a semiconductor device

Abstract: First and second dummy structures (201 and 202) are formed over a semiconductor device substrate (10). In one embodiment, portions of the first dummy structure (201) are removed and replaced with a first conductive material (64) to form a first gate electrode (71) and portions of second dummy structure (202) are removed and replaced with a second conductive material (84) to form a second gate electrode (91). In an alternate embodiment, the dummy structures (201 and 202) are formed using a first conductive material (164) that is used to form the first electrode (71). The second electrode is then formed by removing the first conductive material (164) from dummy structures (202) and replacing it with a second conductive material (84). In accordance with embodiments of the present invention, the first conductive material and the second conductive material are different conductive materials.

Semiconductor device with test-only leads

Abstract: A semiconductor device (10) includes test-only leads (20) and operational leads (18). Operational leads (18) provide access to portions of a semiconductor die (12) needed for device operation. Test-only leads (20) provide access to portions of die (12) which are not needed for device operation, but which are needed during manufacturing tests. Operational leads (18) have an external configuration which facilitates attachment to a user substrate. Test-only leads (20) have an external configuration which enables electrical access to the device for test purposes; however, the test-only lead configuration makes attachment to the user substrate difficult. Since the test-only leads (20) and the operational leads (18) have two different external lead configurations, overall lead pitch is reduced, enabling device (10) to be made very small. Yet, complexity of mounting device (10) to a user substrate is not increased since the pitch between adjacent operational leads (18) can be made larger than the overall lead pitch.

Steady-state analysis and design of a switched-capacitor DC-DC converter

Abstract: A representative switched-capacitor DC-DC converter topology is presented, circuit operation is explained, and control strategies are identified. State-space averaging is used to analyze steady-state performance and to develop control criteria and design equations. The analytical results are verified by SPICE simulation. >

Wireless messaging device with selectable scroll display and message pre-fetch

Abstract: A system, method and computer readable medium for scroll displaying of message information stored in message memory (418) of a wireless messaging device (400). The wireless messaging device (400) fetches additional message information from a wireless messaging server (112) over a wireless network, and stores in message memory (418) the additional message information received over the wireless network prior to reaching the end of scroll displaying the stored message information. Additionally, a plurality of received messages can be scroll displayed according to a message receive order or other priority.
