Title: Enhancement of signal-detection capability of gps systems
Inventor: DA REN
IPC: G01S1/00
Filed: 2001-01-09
Abstract: Estimated Global Position System (GPS) navigation data is used to increase the signal integration interval. In one embodiment, a WAG (wireless assisted GPS) server receives GPS signals and demodulates the navigation data modulated onto the GPS signals. The WAG server utilizes known features of the demodulated navigation data to generate estimated navigation data for the satellite. This estimation can be made several seconds or even minutes ahead of time. The wireless terminal uses this estimated navigation data to perform a data wipe-off operation to enable the integration interval to be increased (e.g., beyond 20 ms), thereby increasing overall signal-detection sensitivity at the wireless terminal. In another embodiment, information from strong GPS  signals is used to detect weak GPS signals from other satellites. In this embodiment, strong GPS signals are received directly by the wireless terminal from the satellites.  After strong GPS signals have been detected, the strong GPS signals are demodulated to compute satellite ephemerides including navigation data. The demodulated navigation data is then matched with known features of the navigation data to estimate the navigation data for weak GPS signals. The estimated navigation data is then used to increase the integration interval for weak GPS signals so that weak GPS signals can also be detected at the wireless terminal.

Title: Solid state transformer
Inventor: SUDHOFF SCOTT D
IPC: H02M5/22
Filed: 1999-06-02
Abstract: A solid state distribution transformer (T) provides transformation between voltage levels through the use of power electronic converters rather than through the use of magnetics, al-though a high frequency isolation transformer (22) is also used. Advantages of this device over a traditional distribution transformer include no mineral oil, less weight, smaller, mitigation of all power quality issues at the load (can compen-sate for non-sinusoidal loads, DC offset loads, input power factor at input of transformer re-gardless of unity power factor at output of trans-former.   The solid state distribution transformer (T) also features a DC bus capable of supporting motor drives and may also be readily interfaced to energy storage devices (such as batteries) for operation as an uninterruptable power supply. In addition, the input frequency (12) is decoupled from the output frequency (30), and changing the number of output phases could be readily achieved. Further, phase shifting of the out-put voltage relative to the input voltage may be achived with the solid state distribution trans-former (T).

Filed: 2001-02-23
Abstract: A grinding machine, that is preferably used for sharpening saw blades has a machine frame that supports a system for positioning the saw blade so that it can be clamped in place, and for advancing the saw blade tooth-by-tooth. In addition, the machine frame supports a positioning system that guides a grinding head. The grinding head has two spindles that are oriented so as to be at right-angles to each other, and independent of each other; these have separate drive systems and are perpendicular to each other. The grinding head is supported so as to be able to pivot and to be adjustable in three spatial directions. In one selected, pivoted position, one of these directions (the Z direction) is oriented so as to be radial to the saw blade. In this position, the axis of rotation of one spindle is in the peripheral direction and the axis of rotation of the other spindle is oriented in the radial direction. Such a grinding head makes it possible to hollow grind tooth-face surfaces with grinding rods that are of small diameter. A separate, high-speed motor is used as a driving system.

Inventor: TOLEDANO JACQUES
IPC: G01N27/60
Filed: 1999-07-28
Abstract: The invention concerns a device and a method for ultrasensitive detection comprising an electrically inert porous sheet sandwiched between two positively charged fine electrodes. The invention uses the capacity of the electrodes, resulting from their powerful electrostatic properties, for sensing marked antibody complexes related to antigens detected in the sample, and to leave marked antibodies non-complexed with said antigens free. The method consists in depositing a sample droplet on the porous material sheet upstream of the electrodes and in detecting downstream of the electrodes, in a signal-zone, the possible presence of an antigen-antibody complex which has diffused in the porous material. The invention is useful for detecting some millipicogrammes of antigen per millilitre of sample.

Filed: 2001-04-09
Abstract: A system and method for synchronizing data records between multiple databases is provided. Each database includes data records that are modified to include at least one pair of synchronization parameters. In a two-database system including a first database and a second database, each data record is modified to include synchronization parameters for both the first and second databases. When an update is made to a data record at one of the databases, an update message is transmitted to the other database including both synchronization parameters from the database where the update is made, along with the updated data record. An efficient master-slave configuration between the databases then enables either database to resolve conflicts without further communications. The system and method scale to systems having more than two databases by modifying the data records in at least one of the databases to include a pair of synchronization parameters for each of the other databases to which it is being synchronized, and by providing a multi-level master-slave configuration. The system and method permits the ability to add and delete records and to securely communicate between all synchronized databases.
