Title: Borehole logging system
Inventor: FUKUHARA MASAFUMI
IPC: G01V3/18
Filed: 1997-01-31
Abstract: For various reasons it may be desirable to change the way a sonde is programmed to behave and respond to the data it receives and operates on, and at present each time this must be done it has been necessary to lift the sonde out of the borehole and then disassemble it to permit the removal of the old ROM and its replacement with a new ROM  storing the new program. The operability and efficiency of such an arrangement is poor. To deal with this, the present invention proposes that the sonde also includes: signal processing means for processing a sampled detection signal according to a predetermined signal processing program; first memory means for storing that signal processing program; and second memory means storing a Writing program for writing the signal processing program in the first memory means according to a command from the ground surface processing apparatus. In this way the sonde's program can be updated from the surface simply by downloading the new program into it, and without the need to bring the sonde up to the surface.

Title: Method for admitting new connections based on measured quantities in a multiple access system for communications networks
Inventor: CHUAH MOOI CHOO
IPC: H04L69/14
Filed: 1998-10-08
Abstract: In a method for admitting new connections based on measured quantities in a wireless commumications network having a base station and remote hosts, the basestation measures and computes performance metrics to determine whether admissionof the new connection could cause a failure to meet the Quality of Service (QoS)promised to already admitted connections. Only if the QoS can be maintained is the new connection is admitted. In one embodiment, the base station may optionally disconnect one or more already admitted lower priority connections if doing so will allow a higher priority new connection to be admitted without loss of QoS to theremaining already admitted connections. In one embodiment, each connection request specifies the average bit rate required and a traffic burstiness factor, the base station measures the number of bytes sent by each connection for a certain period of time and a burstiness factor for the traffic in either direction. The base station computes an equivalent number of admitted connections and determines whether the new equivalent number of admitted connections, after admission of the new connection, would exceed a threshold. The measured quantities can be various metrics related to interference. In one embodiment, uplink Frame Error Rate (FER), an average uplink bit rate, a burstiness factor of the uplink traffic, and a packet loss rate are measured at the base station. Downlink FER is similarly measured at each already admitted remote host and is sent to the base station. Alternatively, the average downlink bit rate, burstiness factor of downlink traffic, and packet loss rate may also be sent from each remote host to the base station. Considering the effect of the average rate and packet loss rate requested by a new connection and the computed equivalent bandwidth, the base station decides whether to admit the new connection based onwhether the QoS of all admitted connections can be maintained.

Title: Assay of peroxidase activity
Inventor: DAVIS PAUL D
IPC: G01N33/533
Filed: 1997-04-15
Abstract: Chemiluminescent detection of molecules of synthetic or natural origin such as proteins and nucleic acids (DNA and RNA), as well as other biologic molecules, is increasingly replacing radioactive detection as the method of choice where sensitivity is critical. In such assays, luminescence is customarily achieved by the oxidation of a luminol or isoluminol substrate in the presence of an oxidizing agent such as hydrogen peroxide or hydrogen peroxide source, such as perborate, and a peroxidase catalyst such as horseradish peroxidase. To obtain useful levels of luminescence (e.g., detectable levels) by customary techniques, a luminescent enhancer is also present during oxidation. It has been found in the practice of the present invention that azine enhancers have contained an impurity which reduces the properties of the chemiluminescent assay working solutions. The present invention describes a working solution, a process of using the working solution, and kits containing solutions which can be mixed to form the working solutions comprising a solution which is useful for the chemiluminescent assay of peroxidase activity comprising: a) at least one chemiluminescent cyclic diacylhydrazide, b) at least one azine enhancer, and c) at least one oxidizing agent wherein said azine enhancer comprises less than 0.005 parts mole/mole total basis of azine compounds having a hydrogen atom bonded to a nitrogen atom of the azine ring. It has generally been found that this hydrogen containing azine is a poisoning agent for the performance of the azine enhancer.

Title: A lamina stack with at least one lamina layer having a plurality of discrete segments and an apparatus and method for manufacturing said stack
Inventor: NEUENSCHWANDER THOMAS R
IPC: B21D35/00
Filed: 1997-06-03
Abstract: A laminated stack (82, 116) having a lamina layer comprised of a plurality of discrete lamina segments (121, 122, 136, 138) and which may also have laminas (118, 120) which define a plurality of outer perimeter configurations.  The invention provides a method and apparatus for manufacturing such stacks (116). Lamina layers (118, 120) comprising a plurality of discrete lamina segments (121, 122, 136, 138) are automatically stacked by positioning the uppermost lamina in a choke barrel (94, 148) near the lower die bed (166) surface and engaging the interlock tabs (144) of the discrete lamina segments (121, 122, 136, 138) with the interlock slots (146) of an uppermost lamina layer in the choke barrel (94, 148) prior to the complete separation of the discrete lamina segments (121, 122, 136, 138) from the remaining portion of the strip stock material (154). Each of the outer perimeter configurations has at least one common choke surface (150). The common choke surfaces (150) form, when the laminas (118, 120, 140, 134) are stacked, a choke contacting surface (150) on the outer perimeter surface of the lamina stack (116) which extends continuously in the axial direction from the top lamina (140) to the bottom lamina (118). A die assembly having selectively actuated punches (90) is used to stamp the laminas (118, 120, 134 140) with a plurality of outer perimeter configurations and the laminas (118, 120, 134, 140) are stacked in a choke barrel (94, 148) with an alignment surface which cooperates with the common choke surface (150) and securely holds the stamped laminas in position while the stack is being formed. Rotation of the choke barel (94, 148) compensates for strip thickness variations.

Title: Promotion of wound healing by chemically-modified tetracyclines
Inventor: RAMAMURTHY NUNGAVARAM S
IPC: A61L15/44
Filed: 1997-08-01
Abstract: A method for improving the healing response of epithelialized tissue (e.g., skin, mucosae) to acute traumatic injury is disclosed.  The method includes employing a tetracycline compound, having substantially no antibacterial activity, to improve the capacity of the epithelialized tissue to heal acute wounds. Specifically, the method involves increasing the rate of collagen accumulation of the healing epithelialized tissue above that associated with wound healing in the individual. The method decreases proteolytic activity in the epithelialized tissue by means of the tetracycline compound, most commonly decreasing collagenolytic activity and/or decreasing gelatinolytic activity.  Collagenase and gelatinase activity have been shown to be decreased by the method of the invention. Preferably, the method is employed to improve the wound healing capacity of human or animal subjects in whom such capacity is impaired. Also, the non-antibiotic tetracycline is preferably administered topically at the site of the wound.
