A lighting system uses an array of lighting elements which provide light in different directions. The intensity of the lighting elements is controlled in dependence on a time-varying parameter related to at least one of a position of a light emitting or light reflecting body, and an intensity, color or color temperature of the light emitted or reflected by the body, such that the system can simulate directional sunlight.

A sieve assembly for separating grain from chaff inside of a combine. The sieve assembly comprises a plurality of longitudinal sieve planks that pivot on their longitudinal axis. A hanging weighted member combined with the sieve planks regulates the angle of the sieve planks relative to the combine. As the combine becomes laterally inclined on a hillside, the weighted member changes its angular position relative to the combine. In doing so, the weighted member causes the sieve planks to pivot on their longitudinal axis so that the sieve planks remain level relative to the horizon. Dividers extend between each sieve plank.

A method, system, and computer program product for monitoring service tickets for information technology (IT) service providers to ensure that levels of service regarding resolving problems identified by a customer are met is provided. In one embodiment, a monitoring server inspects a service ticket in a database to determine a deadline for when a problem associated with the service ticket must be resolved. The server then determines a deadline approaching alert time. This deadline approaching alert time is a time at which a help desk user must be notified that the deadline for resolving the problem must be met is approaching. The server then alerts the help desk user that the deadline for resolving the problem is approaching when the deadline approaching alert time is reached. If the problem is not resolved by the deadline, the server periodically alerts the help desk user when times for status updates, which have been specified by a level of service agreement for updating the customer of the status of resolution of problems that have past deadline, are approaching, thereby ensuring that the IT provider meets its obligations to the customer.

The data processing apparatus comprises main processing logic operable to execute a sequence of instructions in order to perform a process, and subsidiary processing logic operable to perform at least part of the process on behalf of the main processing logic. A memory is provided that is accessible by the main processing logic when performing the process, the main processing logic defining a portion of the memory to be allocated memory accessible to the subsidiary processing logic when performing part of the process on behalf of the main processing logic. Further, a memory management unit is provided that is programmable by the main processing logic and operable to control access to the allocated memory by the subsidiary processing logic. The main processing logic is arranged to program the memory management unit such that for an access request issued by the subsidiary processing logic relating to the allocated memory, the memory management unit produces a memory address and one or more associated memory attributes identifying one or more properties of the allocated memory at that memory address.

A method for engineering of a connection in a WDM photonic network with a plurality of flexibility sites connected by links comprises calculating a physical end-to-end route between a source node and a destination node and setting-up a communication path along this end-to-end route. An operational parameter of the communication path is continuously tested and compared with a test threshold. The path is declared established whenever the operational parameter is above the margin tolerance. The established path is continuously monitored by comparing the operational parameter with a maintenance threshold. A regenerator is switched into the path whenever the operational parameter is under the respective threshold, or another path is assigned to the respective connection. An adaptive channel power turn-on procedure provides for increasing gradually the power level of the transmitters in the path while measuring an error quantifier at the destination receiver until a preset error quantifier value is reached. As the connection ages, the power is increased so as to maintain the error quantifier at, or under the preset value. The path operation is controlled using a plurality of optical power/gain control loops, each for monitoring and controlling a group of optical devices, according to a set of loop rules.

A method is provided for dynamically allocating the radio resources of a satellite and a very high throughput satellite system configured to implement this method. The method of allocation is executed by a piece of ground equipment called a Radio Resource Manager. The method of allocation according to the invention, allocates dynamically in time frequency resources to each spot of the multibeam coverage in accord with the conditions of propagation of the radio signals (in particular the attenuations due to bad weather) prevailing in the spots, with the current and future spot data traffic profile, with the level of interference generated in the neighbouring beams. The method preferentially applies in respect of downgoing forward links, that is to say from the satellite to the user terminals.

Provided are a plasma display panel (PDP) device using a sub-field mode and a method of driving the PDP device. The method of driving the PDP includes allocating a first event pulse for generating an even number of light pulses or a second event pulse for generating an odd number of light pulses to each sub-field, and outputting sustain pulses, which generate light pulses, according to the allocated event pulse. Thus, linearity of the gray level can be improved and an image quality can be improved.

A concrete floor leveling device includes a transmission device and a power source is located in a body and connected to wheels which are connected to the body. A connection unit is connected to the body and a blade is connected to the body by the connection unit. The power source outputs a stable power to drive the blade to level the concrete floor and to ensure that the blade levels the concrete floor with even force.

A rotor core which has relatively high rigidity, can ensure sufficient magnetic performance, and can be produced at a cheaper cost with a relatively small-scale facility. A claw-equipped core and a yoke are manufactured separately. After fitting the yoke to a fitting portion formed in the claw-equipped core, a part of the claw-equipped core in the vicinity of the fitting portion is axially pressed to plastically flow into an annular groove formed in the yoke, thereby integrally joining the claw-equipped core and the yoke to each other. Thus, a large-scaled manufacturing facility is not required, and claws of the claw-equipped core are hard to open in the radial direction even under the action of a centrifugal force during high-speed rotation. A stator core and the claws of the claw-equipped core can be positioned closer to each other, and deterioration of magnetic performance can be avoided.

System and method for detecting a reference signal. A preferred embodiment comprises a latch (such as the latch 320) and a filter (such as the filter 325). The latch tracks a reference signal at its input and reflects the reference signal at its output. The filter can be coupled to the output of the latch and may inject a delay to help eliminate the effects of glitches and noise. When the reference signal reaches a specified value, a control signal from the filter causes the latch to store the reference signal. A delay imparted by the filter ensures that the latch does not store the reference signal until a finite amount of time after the reference signal reaches the specified value.
