Abstract: In an imaging method, periodic maintenance radio frequency pulses (?, ??) are applied to maintain a steady state magnetic resonance excitation in an imaging region. Readout (66) of imaging data from the imaging region is performed during selected intervals between maintenance radio frequency pulses. A spatially selective blood signal suppression sequence (62, 62?) is performed during selected other intervals between maintenance radio frequency pulses. The blood signal suppression sequence suppresses a blood signal in a suppression region different from the imaging region. The blood signal suppression sequence has substantially no zero the moment applied magnetic field gradient.

Abstract: A method for fat-suppressed imaging is disclosed. Such a method may include storing a first spectral component of an echo signal formed at TR/2 from a sample, suppressing a second spectral component of the echo signal at TR/2, re-exciting the stored spectral component after suppressing the second spectral component, and producing an image of the sample based on the re-excited stored spectral component.

Abstract: Disclosed is a filter comprised of activated carbon fibers, wherein said filter has a Virus Removal Index (hereafter “VRI”) of at least about 99%, as measured in accordance with the test method described in the specification. The filter may comprise unbound fibers, or the fibers may be bound with a binder to form a composite of fibers. Also disclosed is a method of removing viruses from a liquid, the method comprising contacting the liquid with a filter comprising activated carbon fibers wherein said filter has a VRI of at least about 99%. Also described is an article of manufacture comprising: (a) a filter comprising activated carbon fibers, wherein said filter has a VRI of at least about 99%; and (b) instructions which inform a user that the filter may be used to remove viruses from a liquid.

Abstract: Described are filters containing free-activated carbon fibers or activated carbon fibers in the form of a composite used for filtering a variety of contaminants, including pathogens, from air. These filters can provide effective and efficient removal of contaminants from air, requiring only short contact time between the air being filtered and the filter itself, with only a minimum pressure drop across the filter. The characteristics of these filters allow for effective filtration with only thin filter layers being required. The process of filtering air utilizing these filters is also disclosed.

Abstract: A tire condition monitoring system (1) comprises a wheel transmitter unit (2) for each wheel of a vehicle. The transmitter unit is mountable in the wheel and has sensors (9, 10) for sensing pressure and temperature in and rotation of the wheel. Signals from the sensors are processed by a processor (9) to produce data which is transmitted via a radio frequency transmitter (23). The data is transmitted with data representing a unit identity code. Transmitted data is received by a receiver unit (5, 6, 7) where it is analyzed to determine the condition of the tire. The receiver unit includes a user operable input for setting threshold limits for the temperature and/or pressure such that if a threshold is passed an alarm is sounded. Each wheel transmitter unit includes a power supply and is arranged so that power is only applied during the sensing and transmission of data. Intervals between transmissions of data can be varied depending on whether rotation of the wheel has been sensed.

Abstract: An MRI system measures the movements of a subject during the acquisition of a series of NMR images and automatically updates the scan parameters such that the image plane or volume tracks the movement of the anatomy of interest. An array of tracking coils fasten to the subject and an NMR measurement pulse sequence is interleaved with the image acquisitions to measure the location of the tracking cols.
