Abstract: A method is disclosed for searching and locating a target device emitting a wireless signal. The signal strength of the wireless signal is detectable and measurable. The method comprises defining a distribution of the signal strength within the search area, on the basis of an initial condition, then iteratively performing steps of interrogating the distribution to determine a plurality of inquiry locations, determining signal strength at those inquiry locations, and updating the distribution on the basis of the determined signal strengths. Iteration continues until a convergence condition is reached, whereby inquiry locations become proximate within a threshold.

While launching an application, a URL of the application, a code package, and a URL of a loading page are obtained; when the URL of the application is a target protocol URL, a loading parameter is read from the code package; the loading parameter is written into the URL of the loading page to generate a new URL of the loading page; and based on the new URL of the loading page, a loading page including display content corresponding to the loading parameter is presented on a display.

Abstract: In a computing system in which resources are available for performance of computing tasks allocated to them, and tasks are requested by requesting computers, a scheduler is associated with each of the requesting computers, to enable that computer to obtain resource for performance of the tasks. Each scheduler obtains resources, in accordance with a locally formulated preference list of resources, on the basis of scheduling tokens issued by resources indicative of reciprocal prioritisation of tasks by resources.

Abstract: Allocation of computational resource to requested tasks is achieved by running a scheduling operation across a plurality of schedulers, each in communication with a subset of network entities, the schedulers establishing a virtual bus. In certain embodiments, the scheduling operation is able to run continuously, allocating newly arriving task requests as resources become available.
