Methods and apparatus identify downhole equipment and correlate input data with the equipment to improve planning and/or inventory operations. For some embodiments, oilfield equipment or tubular goods such as drill pipe include a shaped recess along an outer circumference for receiving a tag cartridge by shrink fitting. Once tagged, detector system configurations at pipe yards may facilitate logging the presence and location of each drill pipe and correlating specific data, such as inspection data, to each drill pipe. Further, this correlation populates a database utilized to achieve other business functions such as forecasting number of additional drill pipe needed to purchase, invoicing customers according to actual tracked wear/use of the drill pipe being returned, and providing well or job specific drill string population using known history pipe joints.

Generally described, the invention provides for an indicia that is associated with a pick up notice left at a pick up location. This indicia is “linked” to the parcel(s) that were intended for pick up at the location, which may be done by a handheld portable data acquisition device that includes a scanning or reading means, allowing information to be acquired from the pick up notice as well as from the parcels, and stored on the handheld portable data acquisition device. Parcel's that do not comply with a carrier's business rules are left at the business location, along with the pick up notice. The indicia is then used to access information about the parcels that were left behind and arrange for re-pick up or alternate pick up instructions, including canceling pick up. The indicia may also be used to track parcels that were picked up as well as to make alternate delivery arrangements for the picked up parcels.

A distributed intercom system including a centralized interconnection unit with a central control device for receiving, processing and transmitting signals, a power distribution device for transmitting a power signal for distribution and at least one cable connection port for receiving a cable connection therein. The system includes a cable with a cable connection element for connection to the cable connection port, and the cable transmits a control signal, a line-level, analog audio signal and the power signal. One or more remote user interface units are connected to and in communication with the centralized interconnection unit through the cable, and the remote user interface unit includes an amplifier, a speaker device and a microphone device. At least one component of the remote user interface unit is powered by the power signal transmitted by the power distribution device.

A method for repairing a stationary turbine nozzle segment having at least one vane disposed between outer and inner structural bands includes providing an engine-run turbine nozzle segment having at least one vane disposed between outer and inner bands, wherein the outer band and the vanes are previously replaced components of the segment and the inner band is an original component of the segment; separating the inner band from the nozzle segment; repairing damage in the outer band and/or the vane; and joining the outer band and the vane to a newly manufactured replacement inner band segment. The replacement inner band segment includes: a structural inner band; and an integral structural collar adapted to receive an inner end of the at least one vane.

In the novel process, a metal oxide is heated in a reactor under 20% H2 gas at a heating rate of 5 degrees C./min to 450 degrees C.; the catalyst is held there for 30 minutes, followed by exposure to 10-20% CO for another 30 minutes; then cooled down to room temperature. The resultant catalyst is then used for synthesis of carbon fibers at 550 and 600 degrees C. In an additional embodiment the catalyst once produced is removed from the reactor, and a new batch of metal oxide catalyst is placed in the reactor to provide a continuous production process.

A method of forming a capacitor includes forming a first capacitor electrode over a semiconductor substrate. A capacitor dielectric region is formed onto the first capacitor electrode. The capacitor dielectric region has an exposed oxide containing surface. The exposed oxide containing surface of the capacitor dielectric region is treated with at least one of a borane or a silane. A second capacitor electrode is deposited over the treated oxide containing surface. The second capacitor electrode has an inner metal surface contacting against the treated oxide containing surface. Other aspects and implementations are contemplated.

A system and method for analog-to-digital conversion using digital pulse width modulation (PWM) is disclosed. The method and system according to the disclosed invention converts an analog input signal to a digital signal in pulse code modulated (PCM) form. The disclosed invention uses a feedback circuit to perform PWM of the analog input signal. The PWM signal is then decimated to obtain the digital signal in PCM form. The system according to the disclosed invention requires lower operating frequency and dissipates lesser power than prior art systems providing the same sampling frequency and resolution. The operation at a lower frequency is achieved by obtaining two samples from every pulse of the PWM signal; the first sample being obtained from the right duty ratio, and the second sample being obtained form the left duty ratio. Further, the disclosed invention has lesser implementation complexity and higher signal-to-noise ratio than prior art.
摘要:
A method for accurately estimating a pose of the human head in natural scenes utilizing positions of the prominent facial features relative to the position of the head. A high-dimensional, randomly sparse representation of a human face, using a simplified facial feature model transforms a raw face image into sets of vectors representing the fits of the face to a random, sparse set of model configurations. The transformation collects salient features of the face image which are useful to estimate the pose, while suppressing irrelevant variations of face appearance. The relation between the sparse representation of the pose is learned using Support Vector Regression (SVR). The sparse representation, combined with the SVR learning is then used to estimate a pose of facial images.
