Patent GB-2363845-A (GB)
Title: Focussing RF flux
Inventor: PENDRY JOHN BRIAN
IPC: G01R33/34
Filed: 2000-06-21
Abstract: A material having magnetic permeability at r.f. frequency, for example, a microstructured magnetic material has a magnetic permeability of negative value but unity magnitude over a particular r.f. frequency range. The singularity in the flux pattern has the result that magnetic resonant disturbances in a plane C,E normal to the line C,D are focussed into a plane D,F also normal to the line C,D, and vice versa. This is particularly applicable to magnetic resonance apparatus, since the material can be used to transfer the r.f. magnetic flux distribution in a target region in a patient, for example at C,E to D,F where the flux may be directly measured by receive coils. Equally, transmit coils may generate flux to be focussed into the target region by the material. Magnetic resonance apparatus may be constructed which does not require gradient coils, and r.f. hypothermia may be carried out in a focussed way, minimising damage to surrounding tissue.

Title: Image data compression method
Inventor: GONDEK JAY S
IPC: H04N1/415
Filed: 2001-11-07
Abstract: A method of compressing a set of image data organized into a matrix of pixels includes selecting a multi-pixel block portion of the data (32), then performing a mathematical function (34) on the multi-pixel block portion to generate a first result. The multi-pixel block portion is divided into at least two segments (40), and a function is performed on each of the segments to generate a second result and a third result (44). Based on a comparison of the first, second, and third results, determining whether or not to compress the multi-pixel block portion (44, 46). The function may be a deviation or mean measurement and serve to determine the noise level and image detail level to determine whether to compress or divide the block into sub blocks. Sub blocks may be recursively analyzed for compression or subdivision until all sub blocks are compressed or divided into single pixels.

Title: Servicing cooling systems for electronic devices
Inventor: LAW ALLAN RANDALL
IPC: G06F1/20
Filed: 2004-12-10
Abstract: An apparatus and method for replacing a CPU cooling system, for example, a fan, while a computer continues to operate has a mechanism for maintenance personnel to signal that cooling fan replacement is about to begin. In response to the signal, a control mechanism causes the CPU to shift into an operating mode in which heat generation is reduced. In some cases, a clock frequency of the affected CPU and/or a duty cycle at which the CPU operates is reduced. After the fan has been replaced the control mechanism returns the CPU to a normal operational mode, for example, by increasing the clock frequency or duty cycle to a normal level. During the fan replacement procedure, the CPU and its software continues to run at lower than normal performance.
