摘要:
An image acquisition system has a computer and one or more imaging devices coupled thereto. Each imaging device has a device memory and is capable of capturing and storing a digital image in its memory. An image device manager is implemented in software on the computer to control imaging device operation. The image device manager presents a user interface (UI) within the familiar graphical windowing environment. The UI has a context space pertaining to a particular imaging context (e.g., scanning, photography, and video). The UI also has a persistently-visible imaging menu positioned within the context space that lists options particular to the imaging context. The image acquisition system also includes a set of application program interfaces (APIs) that enable applications to manage loading and unloading of imaging devices, monitor device events, query device information properties, create device objects, capture images using the devices, and store or manipulate the captured images.

摘要:
A system and method for automatically identifying and configuring interface boards connected to a computer bus is disclosed. Each interface board contains a pair of interface ports that can be addressed by the system and a unique identification address. The interface boards are instructed to serially read the identification address and place a logic 10 in the two least significant bits of the data bus if the first data bit is a logic one. The serial read instruction is performed twice for each data bit in the identification address with a logic 01 data pattern placed on the data bus for the second serial read to assure that a floating data bus is not causing false readings. If no interface board responds to any particular read identification instruction, the system assigns a logic zero for that particular bit of the identification address. Any interface board not having a logic one for a particular first data bit in the identification automatically places itself in a disabled state if the first and second serial read instructions indicate that another interface board did have a logic one for that particular data bit of the identification address. By the time that the system has read all of the identification bits, one and only one interface board will have been identified and enabled. The system can read registers on the interface board to determine which resources are required for operation of that board and assigns parameters such as I/O address, interrupt line, and data channel line. The system enables the other previously disabled interface boards and repeats the identification instructions until all interface boards have been identified and configured.
摘要:
A system for configuring a network adapter of a computer without user intervention. Device information for the devices of the computer, including each network adapter, is collected to uniquely identify the devices and to describe the device characteristics associated with the operation of those devices with the computer. Computer resources, which support the functions of the devices within the computer, are allocated based upon this device information. This allocation process prevents a potential conflicting use of computer resources by the installed devices. A device driver, which enables communications between a corresponding device and the computer, is also identified and loaded for each of the devices in response to the allocation of computer resources. In response to loading the driver for each network adapter, each network configuration routine or layer for a particular interface of the corresponding network adapter is identified. In response to the identification of these layers, each identified layer for the particular interface is loaded. In turn, layers are identified and loaded for each of the remaining interfaces of the corresponding network adapter.
摘要:
A system for managing the configuration of devices of a computer system. Device information is obtained to uniquely identify each device and to describe the device characteristics associated with device operation. To obtain device information, a particular device is detected on a selected system bus and thereafter assigned an identification code that uniquely identifies the detected device. A system bus code, which uniquely identifies the selected system bus, is appended to the identification code, thereby forming a device identification code associated with the particular device. Logical configuration data, which supplies configuration requirements for device operation, is also obtained for the detected device. This data collection process is repeated until device information is obtained for each of the devices connected to the selected system bus. Resources are allocated to each device based on the device identification code and the logical configuration data. This resource allocation process prevents a potential conflicting use of the resources by the devices. A device driver, which enables communications between the corresponding device and the computer system, is identified and loaded for each of the devices in response to the device information. If the computer system contains more than one system bus, then the tasks of collecting device information, allocating resources, and identifying and loading device drivers are completed for each of the remaining system buses.
摘要:
A system for allocating resources for use by devices of a computer system. A possible configuration of elements of a resource is obtained. This possible configuration defines the resource elements that are appropriate for operating the devices within the computer system. For a selected device, a determination is made whether a particular resource element is available for use by this device. If not, another possible configuration is obtained and the process begins anew. In contrast, if the particular resource element is available, then this resource element is assigned for use by the selected device. This resource allocation process continues until resource elements have been assigned to the remaining devices.

摘要:
A system for managing the assignment of device drivers to devices of a computer system. The computer system can maintain device-related information for a primary device and for devices that are "compatible" with the primary device. This device information supplies an indication of whether a device driver intended for primary use with a device is maintained by the computer system. Moreover, the device information provides an indication of whether one or more device drivers compatible with the primary device are maintained by the computer system. During assignment of device drivers to devices of the computer system, the device information is examined to determine whether the intended device driver for the primary device is available to support the operations of that device. If not, the device information is examined to determine whether a device driver for a device that is compatible with the primary device is available for supporting computer operations of the primary device. In this event, if the device information lists more than one device that is compatible with the primary device, then the compatible device having the highest priority or ranking can be selected and the device driver for the selected device is used to support the operations of the primary device.
