Abstract:
Twin roll caster for casting metal strip. Metal is delivered through a distributor (18) and delivery nozzle (19) between a pair of casting rolls (16) to form a casting pool (30) supported on rolls (16) and confined by end plates (56). Rolls (16) are rotated to deliver cast strip downwardly from the nip between them. Rolls (16) are mounted on carriers (104) moveable to allow rolls (16) to move bodily toward and away from one another. Biasing units (110, 111) act on the roll carriers (104) to force them against central stops (107) and to provide roll biasing forces. Stops (107) are adjustable to set the width of the nip between the rolls (16). Biasing units (110) comprise biasing springs (112) whereas biasing units (111) comprise hydraulic actuators (113).
Abstract:
The invention relates to different designs of a microelectronic device comprising an array of heating elements (HE) with local driving units (CU2) and optionally with an array of sensor elements (SE) adjacent to a sample chamber (SC). By applying appropriate currents to the heating elements (HE), the sample chamber can be heated according to a desired temperature profile. The local driving units comprise means for compensating variations of their individual characteristics.

A secure method for updating computer firmware online is described. The firmware storage locations are write protected prior to loading the operating system. Updating the firmware after loading the operating system helps to reduce downtime.
Abstract:
Physical barriers (210) are present between neighbouring pixels (200) on a circuit substrate (100) of an active-matrix electroluminescent display device, particularly with LEDs (25) of organic semiconductor materials. In order to reduce parasitic capacitance in the circuit substrate, the invention forms these barriers (210) with metal or other electrically conductive material (240) that provides at least part of the signal lines (160) at a higher level than the circuit substrate (100). This conductive barrier material (240) is connected to the matrix circuitry within the substrate (100) but is insulated (40) at least at the sides adjacent to the LEDs (25). Preferably, an inter-capacitance guard line (9) is included in the circuit substrate (100) between the signal lines (160) and the circuitry in the substrate (100).
Abstract:
An active matrix electroluminescent (EL) display device has a switching circuit for each display pixel which has a drive transistor (30) and a cascode transistor (32) in series with the associated EL display element (20). The switching circuit is operable in two modes, a first mode in which an input current is sampled by the drive transistor (30) and a second mode in which the drive transistor drives a current corresponding to the input current through the EL display element (20). This configuration uses the same transistor for current sampling as for current driving, thereby avoiding the need for matched transistors. The cascode transistor increases the output impedance and ensures that no voltage fluctuations pass to the drive transistor, so that a constant current supply is maintained.
Abstract:
Methods and architectures for performing hardware error handling using coordinated operating system (OS) and firmware services. In one aspect, a firmware interface is provided to enable an OS to access firmware error-handling services. Such services enable the OS to access error data concerning platform hardware errors that may not be directed accessed via a platform processor or through other conventional approaches. Techniques are also disclosed for intercepting the processing of hardware error events and directing control to firmware error-handling services prior to attempting to service the error using OS-based services. The firmware services may correct hardware errors and/or log error data that may be later accessed by the OS or provided to a remote management server using an out-of-band communication channel. In accordance with another aspect, the firmware intercept and services may be performed in a manner that is transparent to the OS.
Abstract:
An embodiment of the present invention is a system and method relating to seamlessly enable enhanced management and scripting of a computer system and its add-in devices. In at least one embodiment, the present invention enables a system administrator or integrator to script a common configuration for multiple devices and then automatically configure the devices using the script. The language construct and central data repository for configuration settings are extended to comprehend a scripting language. A script is read by a script engine during either pre-boot or runtime. The script engine searches a keyword database on the central data repository to determine requested configuration settings. A data offset is corresponding to a specific op-code is used to determine where configuration settings are located, for modification.
Abstract:
A method and system for content pre-fetching during a processing system pre-boot runtime. First, it is determined when a processor of a processing system is in one of a busy wait state and an idle state during a pre-boot runtime of the processing system. Then, content is pre-fetched from a data storage unit of the processing system. The content is pre-fetched based upon a pre-fetch profile. The content is loaded into system memory of the processing system.
Abstract:
Twin roll caster for continuously casting metal strip comprises a pair of parallel casting rolls (16) to which molten metal is supplied through a delivery nozzle (19). The rolls are mounted on roll carriers (104) moveable on a frame (102) to allow rolls (16) to move toward and away from one another. Biasing units (110, 111) allow inward biasing forces to be applied to the roll carriers (104) so as to bias one of the rolls (104) toward the other. The biasing units (110) incorporate biasing springs and means to adjust the thrust exerted by the springs.
