Patent Application
20080223089
This disclosure relates generally to information handling systems, and more to a media base security mechanism and method of use.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Various types of security measures can be taken to ensure the safety of laptop computers and other portable computer systems. For example, various mechanical linkage systems can be used to enable and disable computer systems to ensure they are not stolen or accessed without consent of the owner. In some instances, portable systems can be docked and undocked to access additional resources when needed. However, when configuring portable systems with security devices, various mechanical linkages can impede on space availability internal to housings of portable systems. As such, use of some locking mechanisms can require oversized hardware components to deter theft or other undesired access.
It will be appreciated that for simplicity and clarity of illustration, elements illustrated in the Figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements are exaggerated relative to other elements. Embodiments incorporating teachings of the present disclosure are shown and described with respect to the drawings presented herein, in which:
The use of the same reference symbols in different drawings indicates similar or identical items.
The following description in combination with the Figures is provided to assist in understanding the teachings disclosed herein. The following discussion will focus on specific implementations and embodiments of the teachings. This focus is provided to assist in describing the teachings and should not be interpreted as a limitation on the scope or applicability of the teachings. However, other teachings can certainly be utilized in this application. The teachings can also be utilized in other applications and with several different types of architectures such as distributed computing architectures, client/server architectures, or middleware server architectures and associated components.
For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.
According to one aspect of the disclosure, a media base security device can include a lock rod mechanism coupled to a portion of a media base housing including a security lock aperture operable to receive a security lock. The media base security device can also include a release lever accessible external to the housing. The release lever can be operable to release the media base housing when coupled to a portable computer system. The release lever can include a lock rod seat operable to engage a lock rod extending from the lock rod mechanism in response to locking the security lock.
According to another aspect of the disclosure, a method of operating a media base security device is disclosed. The method can include installing a security lock within a security lock aperture of a media base housing, and actuating the security lock. In one form, the actuating can cause the security lock to provide a first state to displace an actuator of the security lock towards a lock rod mechanism and contact a portion of a lock rod mechanism using a portion of the security lock. The actuating can further cause the security lock to extend a lock rod of the lock rod mechanism a distance away from the security lock, and inhibit rotation of a release lever to undock a portable computer system.
According to a further aspect of the disclosure, an information handling system is disclosed. The information handling system can include a media base including resources operable to be accessed by a portable computer system when docked. The media base can include a media base housing having a lock rod mechanism coupled to an internal portion of the media base housing. In one form, the lock rod mechanism can be located proximal to a security lock aperture that can receive a security lock. The media base can also include a release lever accessible along an external portion of the media base housing. In one form, the release lever can be operable to release the media base housing from the portable computer system. The release lever can further include a lock rod seat operable to engage a lock rod extending from the lock rod mechanism in response to actuating the security lock.
In accordance with one aspect, the media base 104 can include a media base housing 116 having a top surface 118 and one or more mounting couplers 120 operable to be coupled to the docking interface 112 of the portable computer system 102. The media base 104 can further include a release lever 124 that can be operated to disengage the portable computer system 102 and the media base 104. The media base 104 can also include a security lock interface 126 that can be engaged by a security lock (not illustrated) such as a notebook locks or other computer system locks such a Kensington lock having model number KMW64068E, a Targus lock having model number PA450U, PA410U, or any other notebook or media base lock that can be used as desired.
During operation, the portable computer system 102 can be placed on the media base 104 to access additional resources. For example, the media base 104 can enable access to one or more USB ports such as a USB 2.0 compliant communication port, a media bay that can provide access to Read/Write (R/W) optical drives, Digital Video Disk (DVD) drives, floppy disk drives (FDDs), hard disk drives (HDDs), and other media devices. The media base 104 can further provide access to a general purpose input output (GPIO) interface, serial communication ports, and parallel communication ports. A user can lock the media base 104 and the portable computer system 102 by inserting a security lock into the security lock interface 126. A user can actuate the security lock thereby causing the media base 104 to be securely coupled to the portable computer system 102. In one form, the security lock can actuate a locking mechanism of the media base operable to secure the media base 104 and the portable computer system 102, and restrict movement of the release lever 124. In this manner, the media base 104 and the portable computer system 102 can be maintained in a secure operating environment.
In one form, the media base 202 can also include a first side portion 216 including a security lock aperture 218 that can be coupled to a security lock 220. The media base 202 also includes a second side portion 222 and a release lever 224 operable to release a portable computer system (not illustrated) when coupled to the media base 202. The release lever 224 further includes a lock rod seat 226 operable to engage the second end 210 portion 208 of the lock rod 206. The lock rod mechanism 204 further includes a spring actuator 228 displaced around the lock rod 206 and between the first flange 212 and the second flange 214. According to a further aspect, the lock rod mechanism 204 can include a third flange 234 operably coupled to the spring actuator 228.
During use, a user can insert the security lock 220 into the security lock aperture 218. When actuated (as illustrated), the security lock 220 can interface the first end 206 of the lock rod 206 and maintain a force on the lock rod 206 away from the first side portion 216. In this manner, rotation of the release lever 224 away from the second side portion 222 can be inhibited thereby limiting engagement of the slide bar seat 230 to the slide bar 232. As such, the media base 202 can be secured to a portable computer system.
During operation, a user can insert the security lock 310 into the security lock aperture 308. The security lock 310 can be actuated to contact the first end 320 of the lock rod 318. Upon actuating the security lock 310 (e.g. rotating to a locked position), the lock rod 318 can be extended toward the lock rod seat 326. In one form, the lock rod 318 need not contact the lock rod seat 326 but can restrict movement of the lock rod seat 326 when a release lever may be rotated. In this manner, the lock rod seat 326 can restrict movement of a release lever thereby maintaining a coupling or docking of a portable computer system and the media base. According to one aspect, a third flange 328 can be provided to couple the spring actuator 324.
According to a further aspect, as a user removes the security lock 310 from the security lock aperture 308 (e.g. unlocks the security lock), the spring actuator 324 retracts toward the side portion 304 and the lock rod 318 can be displaced toward the side portion 304 of the media base housing 302. In this manner, rotating the release lever and the lock rod seat 326 will not be inhibited by the lock rod 318, and the media base housing 302 and the portable computer system can be detached as desired.
In one form, the media base 402 can also include a first side portion 416 including a security lock aperture 418 that can be coupled to a security lock 420. The media base 402 also includes a second side portion 422 and a release lever 424 that can be rotated away from the second side portion 422 (as illustrated) to release a portable computer system (not illustrated) when coupled to the media base 402. The release lever 424 further includes a lock rod seat 426 operable to engage the second end 410 of the lock rod 406 when the lock rod 406 is extended by the security lock 420. The lock rod mechanism 404 further includes a spring actuator 428 displaced around the lock rod 406 and between the first flange 412 and the second flange 414. According to one aspect, a third flange 434 can be operably coupled to the spring actuator 428.
As illustrated, the security lock 420 is unlocked or removed, and the spring actuator 428 extends the lock rod 406 towards the security lock aperture 418 giving sufficient clearance to the lock rod seat 426 when rotated. As such, when the release lever 424 rotates away from the second side portion 422, the slide bar seat 430 can contact the slide bar 432 operable to disengage the docking interface of the media base 402 and the portable computer system.
Upon activating the lock, the method can proceed to decision block 510, and if the lock is not deactivated (e.g. unlocked, removed), the method proceeds to block 512 and the locking mechanism maintains inhibiting rotation of the release lever. If at decision block 510, the lock has been deactivated, the method can proceed to block 514 and the lock actuator can be released. In one form, releasing the lock actuator can include operating a locking mechanism that retracts a lock pin that may be inhibiting rotation of a release lever. The method can then proceed to block 516 and a user can remove the security lock from the security lock port or aperture. A user can then actuate a release lever at block 518, and the portable computer system and the media base can be separated at block 520. The method then proceeds to block 522 and ends.
