Abstract: An improved portable notebook computer having a base (15) connected to a display unit (20) that folds along a spine (26). The display unit (20) is pivotally coupled to the base (15) for motion and houses a plurality of display components including a light source (85), light guide (80) and LCD (50). The display drive circuits (115), light source (85), power board (165) and related display components are relocated to the base (15) reducing the thickness and weight of the display unit (20). PWB's (115, 120, 125) used to control LCD (50) display functions are maintained on the display case back (70) to take advantage of available space within the display unit (20). A flexible circuit (330) extends from the base (15) to the display unit (20) to connect the display drive circuits (115) to the PCB's (115, 120, 125) for controlling LCD (50) display functions.

Abstract: Generally, according to the present invention, the sidewall of the adhesion layer (e.g. TiN 36) in a lower electrode is pre-oxidized after deposition of an unreactive noble metal layer (e.g. Pt 38) but before deposition of an HDC material (e.g. BST 42). An important aspect of the present invention is that the pre-oxidation of the sidewall generally causes a substantial amount of the potential sidewall expansion (and consequent noble metal layer deformation) to occur before deposition of the HDC material. One embodiment of the present invention is a microelectronic structure comprising a supporting layer having a principal surface, and an adhesion layer overlying the principal surface of the supporting layer, wherein the adhesion layer comprises a top surface and an expanded, oxidized sidewall (e.g. TiO.sub.2 40).

Abstract: A transparent telephone access system using voice authorization includes a method and system (30 and 60) to protect against the unauthorized use of telephone network (20). By receiving a spoken telephone number (14) from telephone unit (16) and recognizing the spoken phrase that corresponds to telephone number (24), the method and system permit transmission through telephone network (20) to telephone (22). The method and system record spoken phrase (14) in voice recognition server system (18). For the spoken phrase, a voice-template is formed and compared with a voice template formed from a composed phrase including pre-existing or stored spoken digits. In response to the comparison, use of telephone system (16) through telephone network (20) is permitted.

Abstract: Portable electronic devices, such as notebook computers, are provided with the capability of a low profile and light weight keyboard, allowing greater reduction in the size and weight of portable computers without compromising the functionality. In specific embodiments, the present invention provides laptops, notebooks, and sub-notebooks with a low profile keyboard having a polymer top surface. In an embodiment of the invention, a structural rib 214 surrounds at least some portion of the key to advantageously provide a firm offset of the key top from the circuit board 206 for increased key travel over prior art designs. In another embodiment of the present invention, the keyboard key includes alignment pistons 218 affixed to the flexible key layer 202 and extend into holes in the circuit board 206 to provide advantages such as keeping the key's top surface flat, preventing the key from tilting or collapsing on only one or two sides.

Abstract: An apparatus and method for converting a subtractive device decode cycle to a peripheral component interface device decode cycle comprising a data communications bus (45), an interface (110) to the data communications bus (45), a function decoder (125) and device decoder (12) coupled to the interface (110). The function decoder (125) and device decoder (120) detect the presence of predetermined command and device types, respectively, on the data communications bus (45). The function decoder (125) and device decoder (120) feed a device select drive circuit (135) when the proper address and command types are detected. Device addresses in preselected ranges are pass-through and maintained internally in order to prevent the subtractive decode agent (90) from grabbing the bus cycle. Also, a positive decode cycle detection circuit (130) is operably coupled to the device select drive circuit (135) to detect the presence of positive decode cycles after the subtractive decode device select signal has been asserted.

Abstract: The present invention provides a method and a circuit architecture whereby a time delay for optical signals in an integrated optical circuit is implemented in a hybrid configuration. For example, a hybrid time delay circuit could be implemented with a three chip set composed of a switch chip 34 placed between two delay chips 36,38. The delay chips may include one or more delay loops 44 and preferably an associated bypass loop for each delay loop 42. The switch chip contains an optical switch 20 for each delay loop on the delay chips and may contain switch control circuitry or an interface to external switch control circuitry.

Abstract: A sensor 20 is formed on semiconductor substrate 22. Dielectric layers 23 and 24 are formed on the face and backside of substrate 22, respectively. Metal leads 26 and 28 contact the substrate through openings in the dielectric layer 23. The leads 26 and 28 are also connected to the set of interleaved longitudinal contact fingers 27 and 29. Additionally, a pair of backside contacts 30 and 32 are formed on the dielectric layer 24. The backside contact 30 is in contact only with the metal lead 26 through a conductive region 34.

The mirror is suspended adjacent the top surface by at least two supporting elements. At least one supporting element is displaced from an edge of the mirror. The supporting elements, being collinear, define an axis of rotation about which the mirror may oscillate to steer incident light through an angle.
