Title: Apparatuses and methods for signal strength measurement in a wireless communication system
Inventor: RAITH ALEX KRISTER
IPC: H04W72/12
Filed: 1997-10-10
Abstract: Methods and devices for measuring signal strengths by mobile stations in a wireless communication system are described. More particularly, while transmitting and receiving on a channel, signal strength measurements may be required. For instance, the received signal strength of broadcast information slots at the beginning of a superframe may be measured at predetermined times for several carriers. However, the mobile station may be busy performing information reception or transmission tasks. According to one exemplary embodiment, the signal strength measurements may be delayed when the mobile is transmitting and receiving on a channel, and then more frequent signal strength measurements may be made when there is no communication. In other words, the signal strength measurements do not have to occur uniformly in time, but may be more frequently performed if they have been delayed. Alternatively, the mobile station can "steal" one or more time slots to perform the signal strength measurements by ignoring its tasks of receiving and/or transmitting information.

The proximal actuation handle (12) includes a shaft (30) and a spool (34) slidably mounted on the shaft (30). The actuation handle (12) is coupled to the proximal ends of both the flexible tubular member (14) and the control member (23). Lumens of the tubular member (14) form irrigation and aspiration conduits (72, 74). The distal assembly (22) includes a hollow jaw cup (88) coupled to the aspiration conduit (74), and a hollow movable jaw (90) coupled to the irrigation conduit (72). The movable jaw (90) is coupled to the control member (23), such that actuation of the actuation handle (12) moves the movable jaw (90) relative to the jaw cup (88). Moving the hollow jaw (90) into a closed position provides a substantially fluidtight coupling between the irrigation and aspiration conduits (72, 74).

Title: High dynamic range digital fluxgate magnetometer
Inventor: SLATER ERIC K
IPC: G01R33/04
Filed: 1998-11-06
Abstract: An improved digital fluxgate magnetometer (20) that uses digital logic and a high resolution digital to analog converter (40) to digitize a magnetic signal for use by signal processing algorithms. The magnetometer includes an oscillator (11) that outputs an oscillator signal and a magnetic fluxgate sensor (13) having a drive coil (13a) coupled to the oscillator, a feedback coil (13b), and a sense coil (13c). An analog multiplier (14) is coupled to the sense coil and the oscillator and outputs a signal to an analog low pass filter (21). A comparator (22) is coupled to the analog multiplier, and a register (23) is coupled to the comparator and outputs a logical 1 or a logical 0 in accordance with the output of the comparator. A digital filter (27) receives the output of the register and produces a digital output of the digital fluxgate magnetometer. A high resolution digital to analog converter (40) is coupled between the register and the feedback coil of the magnetic fluxgate sensor in a feedback loop of the sensor. The digital to analog converter produces a very high resolution digitized output (typically > 22 bits) that is necessary to adequately represent the dynamic range of the sensor.

Title: Process and apparatus for coating metals
Inventor: SAMSONOV VICTOR
IPC: C25D11/04
Filed: 1997-03-11
Abstract: The invention provides a process for forming a ceramic coating on a valve metal selected from the group consisting of aluminium, zirconium, titanium, hafnium and alloys of these metals. The process includes immersing the metal as an electrode in an electrolytic bath comprising an aqueous solution of an alkali metal hydroxide, providing an opposite electrode immersed in or containing the electrolyte liquid, passing a modified shaped-wave alternate electric current from a high voltage source of at least 700 V through a surface of the metal to be coated and the opposite electrode, wherein the modified shaped-wave electric current rises from zero to its maximum height and falls to below 40 % of its maximum height within less than a quarter of a full alternating cycle, thereby causing dielectric breakdown, heating, melting, and thermal compacting of a hydroxide film formed on the surface of the metal to form and weld a ceramic coating to the metal, and changing the composition of the electrolyte while the ceramic coating is being formed, the change being effected by adding an oxyacid salt of an alkali metal. The invention also provides apparatus for carrying out this method.

Abstract: A retrieval head (10) is disclosed for coupling to a down hole tool for retrieving a drill bit composed of individual drill bit segments (14). The down hole tool is adapted to travel through a drill string and a drive sub (12) attached to the drill string. The tool also releases segments (14) which are clamped between the drive sub (12) and a bit locking sleeve (16). The retrieval head (10) includes a body (30) having a first length (32) and a contiguous second length (34). The first length (32) is of constant diameter.  The second length (34) has a portion (42) of reduced diameter relative to that of the first length (32). The diameter of the first length (32) is dimensioned so that the bit segments (14) can initially collapse radially inwardly wholly onto an outer circumferential surface (38) of the length (32). The reduced diameter portion (42) is dimensioned so that when the bit segments (14) are disposed thereon, the bit segments (14) can pass throught the drive sub (12) and bit locking sleeve (16). In use, when the bit segments (14) clamped to the drive sub (12) are collapsed onto the first length (32) and a down hole tool to which the retrieval head (10) is coupled is pulled upwardly, the bit segments (14) slide relative to and along the head (10) from the first length (32) by abutment of the bit segments (14) with the drive sub (12) and/or bit locking sleeve (16) to the reduced diameter portion (42) where the bit segments (14) together with the retrieval head (10) can pass through the locking sleeve (16) and the drill string to be retrieved.

IPC: G01N33/46
Filed: 2000-02-21
Abstract: The method relates to a rapid identification of wood species by laser induced plasma spectroscopy. The method is used to identify the wood species of a wood sample, such as a lug, a lumber or any other form of wood that is to be identified.  The may be carried out by an apparatus comprising a pulsed laser beam which is focused on a wood sample to be analyzed. The laser pulse vaporizes a small volume of the surface of the wood and produces a plasma. The optical emission of the plasma is subsequently collected and sent to an spectrometer positioned to detect the emission lines of the elements present in the samples by a multichannel detector, such as a photodiode array, a CCD, a CID, a CTD or an array of individual detectors. The identification of the wood species is then conducted by comparing the spectral information to typical spectral information of various wood species stored in a database of a computer. The method allow for rapid, virtually non-destructive and on-line identification of various species of wood.
