Each of the modules is dedicated to perform a different one of a plurality of classes of functionality of the mobile device, where each said module includes a processing element and memory dedicated for use by said module. A time-based intelligence system provides robust storage, access, and processing of information on a mobile device.

Abstract: An automated mobile assistant system provides automated, proactive and anticipatory services for the user of the system. A scheduling system for a mobile device is described and can include a memory to store calendar events and a scheduler to automatically organize the events based on at least one of temporal, geographical, contextual availability, user-preference, past activities, usage pattern, proximity to other users or events, or combinations thereof. In an example, a customizable personal mobile device for communication and organization can include a core engine and a plurality of modules coupled to the core engine to perform a different one of a plurality of classes of functionality of the mobile device, where each said module includes a processing element and memory dedicated for use by said module. A time-based intelligence system provides robust storage, access, and processing of information on a mobile device.

Abstract: The monolithic inductor (30) includes a substrate (38), a spiral metal trace (32) disposed insulatively above the substrate (38), where a parasitic capacitance (56) is generated between the spiral metal trace (32) and the substrate (38), and a depletion layer is generated under the spiral metal trace (32) with a depletion junction capacitance (58) coupled in series with the parasitic capacitance (56). The overall capacitance is thus reduced, which enhances the self-resonance frequency of the inductor (30). For the same self-resonance frequency, a thicker metal trace may be used to implement the inductor, resulting in an improved quality factor, Q.

Abstract: An ocular projection display (12) projects an image directly to the eye (26) of the user (10). The focus of the image may be varied to allow for different user profiles or to relieve the stress of maintaining a fixed focus over a prolonged period of time. Optionally, the ocular projection display (12) can include a location and distance sensor (46) for identifying the location of the user's eyes for proper aiming of the image to the eyes of the user and focus detection circuitry (54) to correct for the user's focusing abilities.

Abstract: A low noise RF input amplifier circuit has an input impedance Z.sub.IN for matched-impedance coupling to an antenna having a resistive impedance R.sub.A. The amplifier circuit has an input and output nodes, an inverting amplifier, and a feedback capacitor. The input node receives an antenna signal which the inverting amplifier amplifies by a frequency-dependent gain -A(s) approaching -A.sub.0 at low complex frequencies s. The feedback capacitor C couples the output node to the input node for negative feedback and is selected to match Z.sub.IN to R.sub.A. When the amplifier's gain A(s) has a rolloff approximated by ##EQU1## where p.sub.1 is a negative pole, the capacitance of C which matches Z.sub.IN to R.sub.A is approximately inversely proportional to both (A.sub.0 +1) and R.sub.A.

Abstract: For mixed signal and RF integrated circuits, the problem of substrate coupled noise can be resolved by using a moat (12) formed in the common substrate to substantially surround sensitive circuits (16). Signal bridges (18, 19) may be formed to provide a path for signals to and from the sensitive circuits (16).

Abstract: A monitorless video projection device (10) for projecting video images (22) onto a surface (24) which is resident in a portable computer (12), a keyboard (54) or projection display unit (72) of a desktop computer (66), a hand-held television (98) or a wireless communication device (85), comprising a digital light processing system (112) which includes a light source (114) that provides incident light (116) to a semiconductor light switch (124) having a plurality of micromirrors (126) for receiving and reflecting the light, a color filter (120) between the light source (114) and the semiconductor light switch (124) and an imaging lens (20) for projecting the light reflecting off the micromirrors (126) onto an existing surface (24), thereby displaying video image (22).
