    摘要： Provided is a process for the removal of metal ions from water which comprises filtering the water through a bed or layer of granular lightburned or hardburned magnesium oxide. The use of granular hardburned or granular lightburned grades of the magnesium oxide provides one with a most effective process for the removal of metal ions, as well as a process which permits a greater throughput of water before the effectiveness of the magnesium oxide decreases substantially.The process of the present invention also involves an acidic backwash to regenerate the granular magnesium oxide. The acidic backwash is used to strip the captured metal ions from the surface of the granules, and has been found to be quite effective. The acid is generally a dilute acid, e.g., about 1 to 10 percent by weight acid concentration.

    摘要： A prosthetic shape sensor comprises a single camera unit and a reflecting surface each mounted on a turntable and arranged opposite each other to define therebetween a space for a stump of a patient. The reflecting surface is shaped to fit between the stump and a leg of the patient. The camera unit includes a light source and the camera unit and the reflecting surface are rotatable together on the turntable through at least 180.degree.. The camera unit can collect a series of silhouette views of the stump upon rotation about the stump.

    摘要： In an instrument used to measure x-rays of the kind in which a wire anode operates in a gaseous atmosphere in a sealed housing to detect x-rays, the instrument is rejuvenated by passing a heating current through the anode to raise its temperature for a period of between two and six hours to convert any impurities to a compound.

    摘要： A memory system and a method for managing the system is described. The system is configured such a plurality of system controllers, which may be RAID controllers, receive requests from the external environment and distribute the requests to a plurality of memory modules such that data may be stored in the memory modules. A global sequence number is assigned to the data of a data stripe so that the operations related to the data stripe are performed in an ordered manner so that the data remains consistent. A plurality of system controllers may comprise a domain and access a plurality of memory controllers and a plurality of domains may include at least one common memory module.

    摘要： A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate physical apertures. Construction of probes can vary by medical application. That is, a general radiology probe can contain multiple transducers that maintain separate physical points of contact with the patient's skin, allowing multiple physical apertures. A cardiac probe may contain only two transmitters and receivers where the probe fits simultaneously between two or more intracostal spaces. An intracavity version of the probe can space transmit and receive transducers along the length of the wand, while an intravenous version can allow transducers to be located on the distal length the catheter and separated by mere millimeters. Algorithms can solve for variations in tissue speed of sound, thus allowing the probe apparatus to be used virtually anywhere in or on the body.
