Biased Insert for Installing Data Transmission Components in Downhole Drilling Pipe

An apparatus for installing data transmission hardware in downhole tools includes an insert insertable into the box end or pin end of drill tool, such as a section of drill pipe. The insert typically includes a mount portion and a slide portion. A data transmission element is mounted in the slide portion of the insert. A biasing element is installed between the mount portion and the slide portion and is configured to create a bias between the slide portion and the mount portion. This biasing element is configured to compensate for varying tolerances encountered in different types of downhole tools. In selected embodiments, the biasing element is an elastomeric material, a spring, compressed gas, or a combination thereof.

Method of producing a wafer scale package

A method for manufacturing a wafer scale package including at least one substrate having replicated optical elements. The method uses two substrates, at least one of which is pre-shaped and has at least one recess in its front surface. Optical elements are replicated on a first substrate by causing a replication tool to abut the first substrate. The second substrate is then attached to the first substrate in an abutting relationship in such a way that the optical element is contained in a cavity formed by the recess in one of the substrates in combination with the other substrate. Thereby, a well defined axial distance between the optical elements and the second substrate is achieved. Consequently, well defined axial distance between the optical elements and any other objects attached to the second substrate, e.g. further optical elements, image capturing devices, light sources, is also established.

Magnetic return path and permanent-magnet fixing of a rotor

A rotor for an electric motor having a short-circuit element that has lamination packets in which the laminations of the short-circuit element are embodied with spring elements which press from two sides against permanent magnets of the rotor and as a result center the permanent magnets in the lateral direction independently of production tolerances. After the insertion of the permanent magnets between the spring elements, the short-circuit element with the permanent magnets is potted, for instance with synthetic resin, or spray-coated with plastic. The rotor has the advantage that it compensates for production tolerances of the permanent magnets.

Controlled oscillator circuitry for synthesizing high-frequency signals and associated method

A method and apparatus for synthesizing high-frequency signals, such as wireless communication signals, includes a phase-locked loop (PLL) frequency synthesizer with a variable capacitance voltage controlled oscillator (VCO) that has a discretely variable capacitance in conjunction with a continuously variable capacitance. The discretely variable capacitance may provide coarse tuning adjustment of the variable capacitance to compensate for capacitor and inductor tolerances and to adjust the output frequency to be near the desired frequency output. The continuously variable capacitance may provide a fine tuning adjustment of the variable capacitance to focus the output frequency to match precisely the desired frequency output. During fine tuning adjustment, the PLL may be controlled by a plurality of analog control signals. The analog control signals may be derived by first generating a plurality of phase shifted signals from a divided version of the VCO output clock. Second, the phase differences between the plurality of phase shifted signals and a divided version of a reference clock may be detected and then converted to the analog control signals.
