2. Description of the Related Art
The modern office environment typically includes multiple computer workstations, with each workstation or group of workstations assigned to a nearby printer. It often falls to members of an information systems staff or other computer support staff to maintain not only the workstations, but the peripheral equipment including printers. In some cases, these printers may be accessible on a network, either directly or indirectly, via connecting workstations. These connections allow a network administrator to update printer resident software and/or firmware and perform other maintenance checks, tests, and functions. However, not all printers are accessible via a network nor are all functions necessarily accessible.
Additionally, when a peripheral device, such as a printer, requires diagnostic operations to be performed, a data processing system associated with the peripheral device is required to be “taken over” for the diagnostics to be run. This process usually involves booting the system from a universal serial bus (USB) device or a bootable diskette. These actions result in an increase in time associated with each service call. Furthermore, the process depends on the system unit functioning for the diagnostics to be run.
Current methods exist for performing local maintenance of a computer peripheral using a portable device. However, the current methods are limited by the fact that an individual is required to travel to each individual peripheral device, hold and point the portable device directly at the peripheral device, wait for diagnostic routines to be ran, and then wait for updates to be performed. This type of process is time consuming especially in an environment when multiple peripherals require updates.
The illustrative embodiments described herein provide a computer implemented method, apparatus, and computer program product for performing maintenance operations on a first set of peripheral devices. The method initiates communication to the first set of peripheral devices using a radio frequency transmission link. A set of diagnostic routines is initiated on the first set of peripheral devices. Data associated with the diagnostic routines from the first set of peripheral devices is received. A number of maintenance updates from a plurality of maintenance updates is selected for each peripheral device in the first set of peripheral devices using the data associated with the set of diagnostic routines. Maintenance operations are performed simultaneously, over the radio frequency transmission link, for each peripheral device in the first set of peripheral devices utilizing the number of maintenance updates.
The novel features believed characteristic of the invention are set forth in the appended claims. The invention itself, however, as well as a preferred mode of use, further objectives and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
With reference now to the figures, and in particular with reference to
In the depicted example, data processing system 102 communicates to peripheral devices 104, 106, and 108 over communication links 118, 120, and 122, respectively. Communication links 118, 120, 122, 124, and 126 utilize a radio frequency transmission link. In this example, the Bluetooth protocol is used as the communication protocol for the radio frequency transmission link. The range associated with the radio frequency may vary from 1 meter, to 10 meters, and even up to 100 meters. Data processing system 102 and peripheral devices 104, 106, 108, 112, and 114 each contain Bluetooth enabled hardware. Alternatively, data processing system 102 or peripheral devices 104, 106, 108, 112, and 114 are coupled to a Bluetooth enabled adapter that supports Bluetooth communication.
Additionally, the peripheral devices may be coupled to a data processing system, such as data processing system 110 and peripheral device 104, or may be a stand alone peripheral device, such as peripheral devices 106 and 114. Data processing system 102 and peripheral devices 104, 106, 108, 112, and 114 may include other types of connections, such as wire, wireless communication links, and/or fiber optic cables.
In the depicted example, data processing system 102 and peripheral devices 104, 106, and 108 form a piconet. In these examples, a piconet is a collection of devices connected via Bluetooth technology in an ad hoc fashion. A piconet starts with two connected devices, such as, for example, data processing system 102 and peripheral device 104. A piconet has a limit number of devices, such as 8 devices in the illustrative examples. All Bluetooth devices are peer units and have identical implementations. However, when establishing a piconet, one unit acts as a master for synchronization purposes, and the other unit(s) will be slave(s) for the duration of the piconet connection. In the depicted example, data processing system 102 acts as the master and peripheral devices 104, 106, and 108 are slaves of to data processing system 102.
A second piconet is illustrated in
A scatternet is two or more independent and non-synchronized piconets that communicate with each other. A slave, as well as a master unit, in one piconet can establish this connection by becoming a slave or a master in the other piconet. The common device shared by the piconets relays communications between the piconets, if the need arises.

In one example, computer readable media 218 may be in a tangible form, such as, for example, an optical or magnetic disc that is inserted or placed into a drive or other device that is part of persistent storage 208 for transfer onto a storage device, such as a hard drive that is part of persistent storage 208.

With reference now to
Data processing system 400 includes hardware layer 401. The hardware layer comprises of at least processing unit 402 and a Bluetooth enabled component 404. Bluetooth enabled component 404 may be an embedded chip on the system board of data processing system 400, or may be a Bluetooth enabled device coupled to the system board, such as a PCI/PCIe component. Alternatively, Bluetooth enabled component 404 may be an external adapter coupled to a port of data processing system 400, such as a universal serial bus port.
Operating system 406 runs on data processing system 400. Operating system 406 may be a commercially available operating system such as, but not limited to, Microsoft® Windows® Vista®. The illustrative embodiments may be implemented in a diagnostic/maintenance software application 408 running on operating system 406. Operating system 406 may run other software applications, such as, but not limited to, a word processing application 410 and an Internet browser application 412.
Diagnostic/maintenance software application 408 communicates to a data store containing software and firmware updates, such as data store 414. Data store 414 may be an internal database, such as Microsoft® SQL Server®, installed on data processing system 400. Microsoft® SQL Server® is a relational database management system (RDBMS) and is a trademark of Microsoft Corporation. Alternatively, data store 414 may be a remote data store installed on a separate data processing system and is accessed by data processing system 400.
In this example, diagnostic/maintenance software application 408 contains communication component 416, diagnostic component 418, update selection component 420, and update component 422. Communication component 416 initiates communication with the Bluetooth enabled peripheral devices. In order to establish new connections, the inquiry and paging procedures are used. The inquiry procedure enables a unit to discover which units are in range, and what their device addresses and clocks are. With the paging procedure, an actual connection can be established. Only the Bluetooth device address is required to set up a connection. Knowledge about the clock will accelerate the setup procedure. A unit that establishes a connection will carry out a page procedure and will automatically become the master of the piconet.
Diagnostic component 418 initiates diagnostic routines on the peripheral devices. Diagnostic routines consist of a series of instructions executed by the processing unit within the peripheral devices. The diagnostic routines test and report on the operational status or functionality of components within the peripheral devices. One status reported by the diagnostic routines may be, but is not limited to, the current version of software and firmware installed on the peripheral devices. The results of the diagnostic routines are received by data processing system 400.
Update selection component 420 uses the data received from the peripheral devices to select applicable maintenance updates for each peripheral device from a data store of updates, such as data store 414. Update component 422 transmits the applicable updates to each peripheral device and initiates installation of the updates on the peripheral devices. Diagnostic component 418 may initiate diagnostic routines on the peripheral devices after installation of the updates to ensure proper functionality of the peripheral devices.
Diagnostic/maintenance software application 408 may contain other components not illustrated in
With reference now to
The process begins by initiating communication to a first set of peripheral devices using a radio frequency (step 500). In this example, the Bluetooth protocol is used as the communication protocol for the radio frequency transmission link. The Bluetooth protocol supports both point-to-point and point-to-multi-point connections.
In these examples, the first set of peripheral devices may be one or more peripheral devices up to seven different peripheral devices to form a piconet. The connection procedure for a non-existent piconet is initiated by any of the devices, such as data processing system 400 as depicted in
The process initiates diagnostic routines on the first set of peripheral devices (step 504). The first set of peripheral devices performs the diagnostic routines and transmits the results to the master device. The process receives the data associated with the diagnostic routines from the first set of peripheral devices (step 506). Data may include, but is not limited to, error codes, software and firmware versions, and diagnostic performance results.
The process then selects a number of applicable maintenance updates for each peripheral device in the first set of peripheral devices from a plurality of maintenance updates using the data associated with the diagnostic routines (step 508). The maintenance updates may be stored in a data store, such as data store 414 depicted in
The process performs the maintenance operations simultaneously, over the radio frequency transmission link, for each peripheral device in the first set of peripheral devices utilizing the number of maintenance updates (step 510). The process re-initiates the communication, previously suspended in step 502, between the data processing system unit(s) capable of communicating to a peripheral device with the first set of peripheral devices (step 512), with the process terminating thereafter.
The process for performing the maintenance operations includes sending the applicable maintenance updates and initializing installation of the maintenance updates on each peripheral device. In another illustrative embodiment, the process initiates diagnostic routines on the first set of peripheral devices after performing the installation of the applicable maintenance updates to ensure proper functionality of the peripheral devices.
With reference now to
The process begins by initiating communication from a peripheral device, such as peripheral device 106, in the first set of peripheral devices to a second set of peripheral devices using a radio frequency transmission link (step 600). The peripheral device in the first set of peripheral devices becomes the master device of a second piconet in which the peripheral devices in the second set of peripheral devices are slaves of the piconet. The second set of peripheral devices may contain one or more peripheral devices. The process initiates performance of diagnostic routines on the second set of peripheral devices (step 602). The process receives data associated with the diagnostic routines from the second set of peripheral devices (step 604). The process then determines if the peripheral device, on which the process is being executed, contains maintenance updates applicable to the peripheral devices in the second set of peripheral devices (step 606). Following a determination that the peripheral device in the first set of peripheral devices contains maintenance updates applicable to a peripheral device in the second set of peripheral devices, the peripheral device in the first set of peripheral devices performs maintenance operations on the peripheral device in the second set of peripheral devices utilizing the maintenance updates (step 608), with the process terminating thereafter.
However, in response to a determination, at step 606, that the peripheral device in the first set of peripheral devices does not contain the maintenance updates applicable to a peripheral device in the second set of peripheral devices, the process initiates communication to other peripheral devices within the second set of peripheral devices using the radio frequency transmission link (step 610). The process requests maintenance updates applicable to the peripheral device in the second set of peripheral devices from the other peripheral devices in the second set of peripheral devices (step 612). Responsive to a determination that at least one of the other peripheral devices in the second set of peripheral devices contains the maintenance updates applicable to the peripheral device in the second set of peripheral devices, the process retrieves the maintenance updates applicable to the peripheral device in the second set of peripheral devices from the at least one other peripheral device (step 614). The process performs maintenance operations on the peripheral device in the second set of peripheral devices utilizing the applicable maintenance updates (step 616), with the process terminating thereafter.
If a determination is made that the other peripheral devices in the second set of peripheral devices does not contain the maintenance updates applicable to the peripheral device in the second set of peripheral devices, the process initiates communication using the radio frequency transmission link to the first set of peripheral devices (step 618).
The peripheral device in the first set of peripheral devices may become the master of the piconet for first set of peripheral devices or may remain a slave of the piconet for the first set of peripheral devices. The first set of peripheral devices may include a data processing system containing maintenance updates, such as data processing system 102 shown in
The process determines if at least one of the peripheral devices in the first set of peripheral devices contains the maintenance updates applicable to the peripheral device in the second set of peripheral devices (step 620). Following a determination that at least one of the peripheral devices in the first set of peripheral devices contains the maintenance updates applicable to the peripheral device in the second set of peripheral devices, the process retrieves the maintenance updates applicable to the peripheral device in the second set of peripheral devices from at least one of the devices in the first set of peripheral devices containing the applicable maintenance update (step 622). The process then initiates communication, using the radio frequency transmission link, to the peripheral device in the second set of peripheral devices (step 624). The process performs maintenance operations on the peripheral device in the second set of peripheral devices (step 626), with the process terminating thereafter.
If the process does not locate the applicable maintenance updates in the first set of peripheral devices, at step 620, the process determines if a communication link can be initiated with a third set of peripheral devices (step 628). If a communication link can be initiated to a third set of peripheral devices, the process initiates communication with the third set of peripheral devices and repeats steps 618-624 in relation to the third set of peripheral devices. If at step 628, a communication link cannot be initiated with a third set of peripheral devices, the process terminates.
Thus, the illustrative embodiments described herein provide a computer implemented method, apparatus, and computer program product for performing maintenance operations on a first set of peripheral devices. The method initiates communication to the first set of peripheral devices using a radio frequency transmission link. A set of diagnostic routines is initiated on the first set of peripheral devices. Data associated with the diagnostic routines from the first set of peripheral devices is received. A number of maintenance updates from a plurality of maintenance updates is selected for each peripheral device in the first set of peripheral devices using the data associated with the set of diagnostic routines. Maintenance operations are performed simultaneously, over the radio frequency transmission link, for each peripheral device in the first set of peripheral devices utilizing the number of maintenance updates.
Furthermore, the illustrative embodiments provide a method for a peripheral device within the first set of peripheral devices to update a second set of peripheral devices. Therefore, the illustrative embodiments provide a method for dynamically performing maintenance operations on multiple peripheral devices at the same time; thus, reducing the amount of man-hours required to maintain peripheral devices. In addition, the illustrative embodiments provide a method for performing maintenance operations on peripheral devices without requiring “taking over” the data processing system coupled to the peripheral device to perform diagnostic and maintenance routines.

The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution.
Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening I/O controllers.
Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modem and Ethernet cards are just a few of the currently available types of network adapters.
