Title: Method for characterization of rock strata in drilling operations
Inventor: UTT WALTER K
IPC: E21B47/00
Filed: 2000-07-12
Granted: 2007-04-03
Abstract: A method and system for determining the relative strength and classification of rock strata in near real-time during drilling operations is provided for use in underground mines. Neural network technology is used to classify mine roof strata in terms of, for example, relative strength or strength index as the roof bolt hole is being drilled (i.e., in near real-time).  Measurements taken while a layer of the rock strata is being drilled are used to compute the specific energy input and convert these data to suitably scaled features. A neural network is then used to classify the strength of the layer.      The neural network can be trained using data of known rock strata classifications prior to using it to classify new measurements. The present system allows for detection of unsafe conditions within the rock strata being drilled, and allows appropriate warnings to be issued in near real-time so that appropriate actions can be taken.

Title: Selection of sites for targeting by zinc finger proteins and methods of designing zinc finger proteins to binds to preselected sites
Inventor: EISENBERG STEPHEN P
IPC: C12Q1/6811
Filed: 2000-01-06
Granted: 2011-06-14
Abstract: The invention provides criteria and methods for selecting optimum subsequence(s) from a target for targeting by a zinc finger protein. Some of the methods of targetgene site selection seek to identify one or more target segments having a DNA motif containing one or more so-called D-able subsites having the sequence 5'NNGK3'. Other methods of the invention are directed to selection of target segments within target genes using a correspondence regime between different triplets of three bases and the three possible positions of a triplet within a nine-base site. In another aspect, the invention provides methods of designing zinc finger proteins that bind to a preselected target site. These methods can be used following the preselection of target sites according to the procedures and criteria described above. The methods of design use a database containing information about previously characterized zinc finger proteins.

Abstract: A method and an apparatus produce current values dependent on the position of the accelerator pedal controlling the power of one or more electric drives for moving a mobile device that is energised by a fuel cell. The time required by the drive or drives to respond to a change in the desired current value produced as a function of the position of the accelerator pedal is kept as small as possible by producing a current value - convertible into a desired torque value - which is held continuously at a value sufficient to ensure that the output voltage of the fuel cell just avoids undershooting a critical limit.

Abstract: A portable master controller for a locomotive remote control system. The portable master controller has a user interface for receiving commands to control the movement of the locomotive. The user interface is responsive to operator commands to generate control signals. A processing unit receives the control signals from the user interface to generate digital command signals directing the movement of the locomotive. A transmission unit receives the digital command signals and generates a RF transmission conveying the digital command signals to the slave controller. A solid-state tilt sensor in communication with the processing unit communicates inclination information to the processing unit about the portable master controller. The processing unit receives and processes the inclination information. If the inclination information indicates that the portable master controller is in an unsafe operational condition, the processing unit generates an emergency digital command signal to the transmission unit, without input from the operator, for directing the locomotive to acquire a secure condition.

Abstract: The invention proposes a method for managing of Signalling ATM Adaptation Layer (SAAL) resources performed in a sublayer comprising the steps of receiving a request from a Layer Management (LM); processing the request in the sublayer; judging whether the processing of the request has been successful, and forwarding a success message to the Layer Management (LM) in case the processing has been successful, or forwarding a failure message to the Layer Management (LM) in case the processing has not been successful. By this method it is guaranteed that the SAAL resources are available as long as the corresponding signalling link/channel is configured in a network element. It further enables detection of SAAL resource defects.
