Abstract: A bottom hole assembly includes a single wire bus, a legacy sensor coupled to the single wire bus, and at least one high frequency communication sensor coupled to the single wire bus. The high frequency communication sensor injects a high frequency signal alternating between high frequency synchronization pulses and high frequency data signals onto the single wire bus. A first high frequency pass filter coupled between the at least one high frequency communication sensor and the single wire bus is also included. The high frequency pass filter passes the high frequency signal to the single wire bus from the high frequency communication sensor. The bottom hole assembly includes a first high frequency blocking filter coupled between the legacy sensor and the single wire bus. The high frequency blocking filter blocks the high frequency signal from the high frequency communication sensor from disturbing a legacy signal at the legacy sensor.

Abstract: A single layer antenna path profile is provided. An antenna assembly for the single layer antenna profile includes a bobbin having a cylindrical body defining an outer radial surface, an inner radial surface, and a central axis. The antenna assembly also includes one or more channels defined in the outer radial surface. In some aspects, each channel is defined by a continuously curved inner surface having a constant radius. In some aspects, the inner surface extends more than 180 but less than 360 and thereby defines an opening in the body. The antenna assembly also includes a coil including a wire wrapped about the bobbin and received within the one or more channels. In some aspects, an arcuate portion of the wire extends through the opening such that a portion of the wire protrudes out of the channel.

Abstract: A logging tool and a method for in-situ, independent calibration of receiver amplifier electronics separately from transmitter electronics. A logging tool can perform in-situ gain and phase calibration on one or more receiver assemblies, each consisting of at least a receiver amplifier electronics and a receiver antenna, and based on a calculated gain and phase of the receiver assembly, determine the true antenna amplitude and phase associated with a measurement made by the receiver assembly. The logging tool can perform in-situ crosstalk measurement and calibration, by determining a crosstalk matrix for all of the receiver assemblies and for each receiver assembly, removing the crosstalk interference from the measurement made by the receiver assembly.

Abstract: A radiation logging tool is provided that includes a scintillator detector for use on a wellbore tool string to characterize earth formations. The scintillator detector has a shutter to allow for the collection of data differentiating between incident radiation, such as backscatter signal, and system noise, such as dark current, vibration noise, electronics thermal noise, and electrostatic noise. The radiation logging tool provides for a method of calibrating and measuring incident radiation by the removal of system noise. The shutter is positioned between the photosensor and scintillation member of the scintillator detector, and is able to switch between open and closed states while the scintillation detector is deployed. Measurements of signal noise can be used to calibrate the sampling signal of incident radiation on the scintillator detector.

Abstract: A system for Internet appliance data entry and navigation includes a reduced keyset remote control unit transmitting a user input keystroke sequence. An Internet appliance receives and parses the keystroke sequence, placing the parsed data into an input buffer. An Internet appliance browser accesses user interface display screens from remote storage via a communications network. The buffer contents define a window within an accessed display screen. The Internet appliance converts the composite display screen for output to a standard television receiver. A user makes option choices and navigates the user interface display screens by activating hyperlinks within the accessed display screens. A standard telephone keypad arrangement is used to create the keystroke sequence, permitting use of a standard or wireless telephone and a hand-held remote control unit for system input and control. An alternative embodiment permits voice input of text, numbers, special symbols, and shortcuts in many languages.

Abstract: A system for using an Internet appliance for sending and receiving digital content files as email attachments includes a system server and an Internet appliance both connected to a communications network such as the Internet. The Internet appliance and system server define communication and control protocols based on server maintained user interface display screens and Internet appliance received reduced keyset keystroke sequences. The protocols define text entry and editing, and option selection and navigation via hyperlinks embedded within the user interface display screens. An email protocol permits selection of server stored digital content files for attachment to outgoing emails and the receiving and viewing-of/listening-to video/audio digital content files that arrive as email attachments. All digital content files are maintained at the server and accessible at the Internet appliance only for viewing via browser and listening.

Abstract: A network access device uses a standard video display to show functional choices and network content received from the Internet to a user. The user directs the functional operation of the network access device with a simple reduced keyset remote control unit having a relatively small number of keys similar to a consumer remote control used for television receivers and video recorders. The control choices are displayed to the user in a unique format with elements associated to characters corresponding to the same characters in the reduced keyset. The display format uses several display areas, some of which can be designated as input focus areas, any one of which can be active at a given time. The device affords low cost ready access to the informational capabilities of the Internet for users at all skill levels by eliminating a full text keyboard and a mouse.
