Patent Issued for Changing Resource Allocation among a Plurality of Concurrently Executing Applications in a Portable Multimode Communication Device in Response to a Change in Usage Scenario
By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventors Tennant, Bryce (Rochester, NY); Weigold, Kenton (Henrietta, NY); Dobri, Tibor (Holley, NY), filed on April 4, 2013, was published online on June 23, 2015, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.
Patent number 9063782 is assigned to Harris Corporation (Melbourne, FL).
The following quote was obtained by the news editors from the background information supplied by the inventors: "The inventive arrangements relate to multimode devices and more particularly to methods and systems for providing controlled access to hardware resources needed for mission critical applications.
"Public safety personnel commonly make use of multiple devices for communication and data processing. For example, a public safety officer may be equipped with one or more of a land mobile radio (LMR), a cell phone, laptop, a tablet computer and so on. Advances in technology have made possible the creation of multimode devices that integrate the functionality of two or more such systems into a single device. In these types of devices, software applications frequently implement important functionality using limited hardware resources (e.g., buttons, knobs, speakers, displays, and processing resources) which must be shared with other applications. While these arrangements can work well in many scenarios, they will often contradict the mission critical expectations associated with public safety equipment. More particularly, a mission critical function may not be available when needed due to requested hardware resources being in use by another, possibly lower priority, function. Whether or not a particular function is deemed mission critical can vary in accordance with different operational scenarios and with different types of users."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "Embodiments of the invention concern a method for providing to a plurality of software applications executing in a software environment controlled access to limited hardware resources on a portable multimode communication device (PMCD). The method begins by establishing a software environment in the PMCD in which a plurality of software applications are executing. Each software application is configured to perform at least one predetermined application function using a respective hardware set. Each hardware set is comprised of a plurality of hardware resources provided on the PMCD. The method involves evaluating a usage scenario of the PMCD based on one or more parameters. Based on such evaluation, selected ones of the hardware resources comprising each set are dynamically allocated to each of the software applications.
"According to another aspect, the invention concerns a portable multimode communication device (PMCD). The PMCD includes a processing device configured to receive data comprising a plurality of parameters and determine a usage scenario for the PMCD based on the parameters. The processing device evaluates the usage scenario to determine a hardware resource allocation for each of a plurality of software applications executing in a software environment on the PMCD. The processing device dynamically re-allocates selected hardware resources in the PMCD based on a change in at least one of the parameters. The re-allocation can provide a first one of the plurality of software applications with access to a hardware resource which is at the same time required by a second one of the priority of software applications. The re-allocation in such a scenario is based on a determination that the first software application performs a function which is determined to be mission critical based on the usage scenario. Access to hardware resources as described herein can be exclusive or shared, depending on the particular hardware resource and the needs of the particular software application."
