An adjacent component can, for example, include one or more operating system components not provided by the OS (e.g., Device Drivers) and/or one or more functions that are not provided by the operating system (e.g., application management, security and/or isolation of applications), effectively serve as an interface to another adjacent layer and/or the OS, or provide Real-Time Operating System (RTOS).05-27-2010
20120151504METHOD FOR CREATING A CUSTOMER-SPECIFIC SETUP FOR A LIBRARY OF DEVICE DRIVERS - A method for creating a customer-specific setup for a library of device drivers, wherein each device driver is a software module, via which a field device, or a field device type, can be serviced. The method permits creation of an individualized, customer-specific setup for the device driver library. This is achieved by the feature that a DTM library setup is expanded automatically by earlier assembled, customer-specific information.06-14-2012
20110145839ABSTRACT DATABASE QUERY - A tangible computer-readable medium encoded with an executable set of instructions for accessing a database with a terminal is provided. A detecting code segment detects connection properties of the database. A determining code segment automatically determines, based on the connection properties of the database and from a plurality of database connectivity drivers stored in a memory, one of the plurality of database connectivity drivers that enables communication with the database. A loading code segment loads the one of the plurality of database connectivity drivers on the terminal to enable the terminal to communicate with the database.06-16-2011
20080222662Method for testing device descriptions for field devices of automation technology - A method for testing device descriptions for field devices of automation technology, which are executed in a frame application running on a computer unit, provides, between the frame application and the device descriptions, a test component, which, on the one hand, is transparent for the communication between the frame application and the device descriptions, and which, on the other hand, tests interface invocations according to a predetermined specification.09-11-2008
20080222661Failover and Load Balancing - Provided are techniques for failover when at least one of a first network adapter and a data path through the first network adapter fails, wherein the first network adapter is connected to a filter driver, and wherein the first network adapter is connected to a second network adapter. With the filter driver, a path fail notification is received that at least one of the first network adapter and the data path through the first network adapter has failed. With the filter driver, packets directed to the first network adapter are rerouted to the second network adapter.09-11-2008
20130125144Device Display Object Infrastructure - Multi-function devices expose multiple functions to device drivers or other lower-level software. Device function providers can interface with such drivers or lower-level software and can provide information, including device identifiers regarding such functions, to a device display object infrastructure. A device display object can then be created that encompasses one or more functions such that, in one embodiment, the device display object corresponds to a single, physical multi-function device. Alternatively, any combination of functionality from one or more physical devices can be combined into a single device display object representing a virtual multi-function device. Properties of the device display object can be set with reference to user-specified settings, remotely maintained metadata, locally available metadata, and information associated with each function. Functions can be ranked such that, if there is a conflict, information from more highly ranked functions is used to set the properties of the device display object.05-16-2013
20080209448Apparatus, System, and Method For Extending A Device Driver To Facilitate A Network Connection To A Remote Event Manager - An apparatus, system, and method are disclosed for providing a network interface to a small computer system interface (“SCSI”) storage device driver. The method includes detecting an event in one of a storage device and a SCSI device driver of the storage device and comparing an event identifier associated with the event to a list of event identifiers. The method includes suspending an application in communication with the storage device through the SCSI device driver and sending a request associated with the event to a remote event manager over a transaction control protocol/Internet protocol (“TCP/IP”) connection, each in response to the event identifier matching a listed event identifier. The method includes receiving a response related to the event from the remote event manager over a TCP/IP connection. The method includes resuming the application after sending the response to the storage device through the SCSI device driver or failing the application.08-28-2008
20120278818On-the-Fly Replacement of Physical Hardware with Emulation - Various aspects are disclosed herein for replacing the hardware backing the memory locations associated with a virtual machine with a backing mechanism. The backing mechanism may have the memory locations appear to contain data convenient to the driver in the virtual machine, typically containing what the hardware would have returned if the hardware had been read from. The data image being returned from the memory locations may travel with the virtual machine even if the virtual machine moves to a different physical machine that does not contain hardware equivalent to the hardware that was recently removed from the virtual machine.11-01-2012
20130152108METHOD AND APPARATUS FOR VIDEO PROCESSING - A method and system for video processing is disclosed. A device driver interface (DDI) call for flipping or updating an overlay may be skipped or ignored, and may not be used by a user mode driver to pass overlay properties to a kernel mode driver (KMD). Instead, the overlay properties may be passed to the KMD at rendering time during a DDI call for rendering. The user mode driver may call a DDI for rendering an overlay frame while simultaneously passing the overlay property data to the KMD. The KMD may store the overlay property data in an overlay flip queue, program the overlay hardware per the overlay property data stored in the overlay flip queue, and flip the overlay in response to the vertical synchronization deferred procedure call.06-13-2013
20120284734UNIVERSAL MEDICAL DEVICE DRIVER ADAPTER - A universal medical device driver adapter that enables the creation of medical device drivers without the need to write custom software for typical medical devices, thereby reducing development time for individual drivers and reducing training time and skill sets requirements of driver developers. Various format parameters are defined, such as baud rate, parity, buffer size, time stamps, tokens, message link, and the like, in an XML device driver file. When a recognized medical device is specified, the corresponding XML file is retrieved and an interface uses the parameters described therein for bidirectional communication with the monitor.11-08-2012
20130212602INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND COMPUTER-READABLE MEDIUM - An information processing apparatus comprises: a display unit configured to display, on a display device, a virtual device object to which a first object of a first device driver corresponding to a first output function of an output apparatus and a second object of a second device driver corresponding to a second output function of the output apparatus are assigned; and an acceptance unit configured to accept a data output instruction to the displayed virtual device object, wherein when the data output instruction to the virtual device object is accepted, said display unit displays information capable of accepting an output instruction to one of the first output function and the second output function.08-15-2013
