  • Patent number: 9336225
    Abstract: Embodiments provide methods and systems for encoding and decoding variable-length data, which may include methods for encoding and decoding search engine posting lists. Embodiments may include different encoding formats including group unary, packed unary, and/or packed binary formats. Some embodiments may utilize single instruction multiple data (SIMD) instructions that may perform a parallel shuffle operation on encoded data as part of the decoding processes. Some embodiments may utilize lookup tables to determine shuffle sequences and/or masks and/or shifts to be utilized in the decoding processes. Some embodiments may utilize hybrid formats.

  • Patent number: 5968758
    Abstract: Antibodies having binding affinity for free IGFBP-1, biological compositions including antibodies having binding affinity for free IGFBP-1, kits for detecting free IGFBP-1 using the antibodies, and cell lines for producing the antibodies are provided. Also provided are devices and methods for detecting free IGFBP-1 and a rupture in a fetal membrane based on the presence of amniotic fluid in a vaginal secretion, as indicated by the presence of free IGFBP-1 in the vaginal secretion. The antibodies that are provided may be characterized by their ability to selectively recognize those IGFBP-1 molecules which are free of IGF-1 and IGF-2, i.e., antibodies which have a binding affinity for free IGFBP-1 that is greater than a binding affinity of the antibody to bound IGFBP-1. These antibodies may also be characterized by their competition with IGF-1 and IGF-2 for binding to IGFBP-1.

  • Patent number: 5722251
    Abstract: An air cooler including a housing having an air inlet zone and an air outlet zone, a heat exchanger mounted in the housing and defining a first plurality of dry channels extending from the air inlet zone to the air outlet zone. Air is passed through the dry channels from the inlet zone to the outlet zone to be cooled and the cooled air constitutes a total airflow. The heat exchanger also defines a second plurality of moist channels each having an inlet and an outlet and alternating with the dry channels. The moist channels are intended for passing the air to be humidified from their inlets to their outlets and in cross-flow direction to the direction of the total airflow. The air to be humidified constitutes an auxiliary airflow which is formed from a part of the total airflow at the air outlet zone and is extracted from such a section of the air outlet zone, which is situated closer to the outlets of the moist channels than to their inlets.

  • Patent number: 5597700
    Abstract: A method and device for detecting fetal membrane rupture by detecting only that insulin-like growth-factor-binding protein 1 (IGFBP-1) which is free of insulin-like growth factors 1 and 2 (IGF-1 and IGF-2) are disclosed. The method is based on the fact that the concentration of free IGFBP-1 in the blood serum is about 10 times lower than that of the IGFBP-1 bound to IGF-1 and IGF-2, while in the amniotic liquid which is contained in the amnion has more than 1000 times the concentration of free IGFBP-1 than the blood serum. Therefore, when even a small amount of amniotic liquid is contained in the vaginal secretion sample, this is clear evidence of the rupture of the fetal membrane having taken place. The method and the device make it possible to diagnose fetal membrane rupture with an extremely high accuracy. Because of the low concentration of the IGFBP-1 in the blood, the admixture of the blood serum to the sample does not affect the results of the test.

  • Patent number: 5481694
    Abstract: An electronic data storage system including a memory, a plurality of magnetic disk units, and a controller. The memory contains an index cross-referencing logical address with physical addresses, an obsolete list and a free list. In response to a "write " command, the controller selects a physical address according to which segment can be used the most quickly, appends a tag to the data to be written, and writes the data to the selected segment. Appropriate entries are made in the index and the free list. The system recovers from memory loss by using a checkpoint log and a set of checkpoint segments on the disk that together contain backups of the index and other critical information needed to restore the system. Group indices are used for roll-back groups; operations on data in a group are invisible outside the group until after a "commit " command is issued.

  • Patent number: 5345575
    Abstract: An indirectly accessed disk storage device comprises a rotating disk memory coupled to an intelligent disk controller. The intelligent disk controller responds to a request to store a packet of data by determining which storage location of the rotating disk memory are available and by selecting from among the available locations a location that can be accessed in a minimum amount of time relative to access time of any other available location. The intelligent disk controller makes its selection dynamically by monitoring the current position of the recording head of the rotating disk memory and by searching a record of available locations to select an optimal location. The intelligent disk controller then stores the packet of data on the rotating disk memory. By optimizing such data write operations, the indirectly accessed disk storage device also effectively optimizes data read operations.
