One or more embodiments of the invention enable improved communication with a database comprising multiple clients utilizing multiple large data objects concurrently. For example when a client system interacts with a server with respect to a data object that is over a threshold size, the system may utilizing a communication methodology that minimizes system resource usage such as CPU utilization and network utilization. In one embodiment of the invention when a client request for an object falls within the relevant size threshold, one or more embodiments of the invention segment the object into smaller size chunks. Hence the server is not required to assemble all data associated with a request at once, but is instead able to immediately start transmitting smaller segments of data. Allowing for the transmission of smaller data chunks prevents the server from allocating large blocks of memory to one object and although the server may be required to handle more memory allocations, each allocation is smaller in size and can therefore be processed much faster. The determination of the chunk size is dependent on inherent system resources such as the amount of server memory, and the available bandwidth of the network. In addition, the determination of chunk size is dependent on environmental factors such as the time of day, the day of the week, the number of users, the number of predicted users for a given time and day based on historical logging, and the current and predicted network utilization for a given time and day. One or more embodiments of the invention obtain the chunk size and optionally obtain a chunk transfer size from a server that may alter these quantities dynamically in order to minimize resource utilization.

A memory system includes a memory controller to control a first memory device and a second memory device. The first and second memory devices are different in terms of at least one of physical distance from the memory controller, a manner of connection to the memory controller, error correction capability, or memory supply voltage. The first and second memory devices also have different latencies.

Memory circuitry, a data processing apparatus and a method of storing data are disclosed. The memory circuitry comprises: a memory for storing the data; and control circuitry for controlling power consumption of the memory by controlling a rate of access to the memory such that an average access delay between adjacent accesses is maintained at or above a predetermined value; wherein the control circuitry is configured to determine a priority of an access request to the memory and to maintain the average access delay at or above the predetermined value by delaying at least some accesses from access requests having a lower priority for longer than at least some accesses from access requests having a higher priority.

A method of prioritising content for distribution from a camera to a server over an Internet Protocol (IP) network, the method comprising: storing a plurality of audio and/or video data packages to be distributed to the server over the IP network; obtaining information indicating the priority at which each audio and/or video package is to be distributed over the IP network, the priority being determined in accordance with the content of the audio and/or video package; and sending each audio and/or video data package over the IP network, the order in which each audio and/or video data package is sent being determined in accordance with the indicated priority.

An overlaid switching network is derived by overlaying perpendicularly one multistage interconnection network with a second multistage interconnection network. The new network is formed by placing a switching element corresponding to the position of switching elements in either multistage interconnection network. Each switching element in the overlaid network has the ports defined by the two multistage interconnection networks as does its interconnection networks. A special case occurs when the number of rows and columns of the first multistage interconnection network is the number of columns and rows of the second multistage interconnection network, respectively. The overlaid switching networks also inherit their upgradeability from the multistage interconnection networks from which they are derived, such as in the case of a redundant blocking compensated cyclic group multistage network.

A light projection system and method for generating an image with three primary colors having a module of first blue lasers, second lasers and a wavelength conversion element configured to emit light at a plurality of wavelengths after absorption of a light beam from the second lasers at an excitation wavelength, the output of the module being a combined light beam having a pre-defined chromaticity where the projector is calibrated so as to provide the pre-defined chromaticity of the combined beam over at least a range of laser drive current values to correct for non-linear performance of the wavelength conversion element.

Some embodiments are directed to a method, corresponding system, and corresponding apparatus for detecting unexpectedly high latency, due to excessive retries of a given storage device of a set of storage devices. Some embodiments may comprise a processor and associated memory. Some embodiments may monitor one or more completion time characteristics of one or more accesses between the given storage device and one or more host machines. Some embodiments may then compare the one or more completion time characteristics with a given threshold. As a result of the comparison, some embodiments may report, by the one or more host machines, at least one error associated with the given storage device. The error may be unreported by the set of storage devices.

The invention discloses a method for measuring and eliminating delay between sounding data and positioning data of an unmanned ship. The method comprises the steps: providing an anechoic pool for single-beam precision measurement, installing a transducer of the unmanned ship on a support of the anechoic pool, transversely transmitting beams, and fixing a positioning module of the unmanned ship at the top of the support. Unique corresponding water depth values are positioned for different positions in the movement process of the unmanned ship, and synchronous change of the positioning data and the water depth data under the condition that the precision and the range are known is achieved.
