Abstract: The current invention concerns a method, a computer system, and a computer program product for blood vessel image In extraction from ultrasound signals, and a method and apparatus for ultrasound imaging A set of ultrasound signals at successive times in a plurality of spatial points is obtained. The ultrasound signals are decomposed as a sum of terms. Each term consists of a time-independent spatial component image factor and a space-independent temporal component signal. The spatial component images are mutually orthonormal. The temporal component signals are mutually orthogonal. A sharpened spatial image for each of multiple spatial component images is determined. A processed image being a bilinear combination of multiple sharpened spatial images is generated.

Abstract: Disclosed is a method for imaging brain activity from a set of ultrasound images I(t) of blood in a brain, wherein a measured spectrum s(P,t,?) is computed at each point P of the ultrasound images, a reference spectrum s(P,?) is determined at each point P, based on measured spectrums at point P, the reference spectrogram having a high frequency edge decaying in a frequency ?min(P) to ?max(P), and a differential intensity is computed as: dI(P,t)=??min(P)?max(P)A(P,?)[s(P,t,?)?s(P,?)]d? wherein A(P,?) is a positive weighting function.

Abstract: A coolant filtration system and method for use with one or more metal working machines. The system includes a housing, pump, conveyer assembly, drum assembly, and centrifugal separator. The housing includes a tank that receives and holds coolant coming out of the one or more metal working machines. The pump is used to drive the coolant through the coolant filtration system. A part of the conveyer assembly is disposed within the housing in order to carry-away workpiece chips from the coolant. The drum assembly is located near the conveyer assembly in order to filter the coolant. The centrifugal separator receives coolant processed by the conveyor and drum assemblies. The system can further include one or more fine filters for additional filtering of the coolant outputted by the centrifugal separator.

Abstract: A sweetening and cleaning system that is used with one or more lapping machines to sweeten a lapping compound in a sweetening mode, and to clean parts of the system itself and parts of the one or more lapping machines with a cleaning compound in a cleaning mode. The system includes a virgin receptacle for holding the lapping compound, a cleaning receptacle for holding the cleaning compound, a waste receptacle for holding waste, and at least one pump.

Abstract: A miniature keyboard for a palm held computer is disclosed. The miniature keyboard includes a plurality of keys for providing input to a hand held computing device. The keyboard includes a platform supporting the plurality of keys. The platform is configured to be sized for use by a single hand and the platforms is selectively foldable to substantially conceal the plurality of keys from view. The keyboard also includes a support structure that couples the platform to the hand held computing device body. The support structure is configured to prevent substantial movement of the platform relative to the hand held computing device body.

Abstract: Embodiments of this invention provide for coupling an accessory device to a back face of a handheld computer while electrically connecting to the handheld computer through a communications or output port. In one embodiment, the accessory device “piggy-backs” on the handheld computer so that the accessory device and handheld computer form a portable combination. An insertion coupling may be used to detachably secure the accessory device with the handheld computer. The insertion coupling used with embodiments of the invention is preferably a snap-in coupling having one or more biased members. The biased members may be contracted to engage an aperture on a back face of the handled computer. When released, the biased members secure the accessory device to the handheld computer.

Abstract: An encasement for a handheld computer is provided. The encasement includes a spine that is slideably engageable with an accessory slot of a handheld computer; and an encasement portion joined to the spine. The encasement portion is dimensioned to encase the handheld computer when the spine is engaged to the handheld computer.
