    Patent number: 8518234
    Abstract: A method for making a ferritic stainless steel article having an oxidation resistant surface includes providing a ferritic stainless steel comprising aluminum, at least one rare earth metal and 16 to less than 30 weight percent chromium, wherein the total weight of rare earth metals is greater than 0.02 weight percent. At least one surface of the ferritic stainless steel is modified so that, when subjected to an oxidizing atmosphere at high temperature, the modified surface develops an electrically conductive, aluminum-rich, oxidation resistant oxide scale comprising chromium and iron and a having a hematite structure differing from Fe2O3, alpha Cr2O3 and alpha Al2O3. The modified surface may be provided, for example, by electrochemically modifying the surface, such as by electropolishing the surface.

  • METHOD AND APPARATUS FOR AUTOMATIC TIME-SHIFTING FOR A CONTENT RECORDER
    Publication number: 20130216198
    Abstract: A content player includes a pausable mass storage device player that can be used to record and play content. The pausable mass storage device can become paused in response to an assertion of a pause signal. Once paused, the content player remains paused until the pause signal is deasserted. The content player also includes an event detector that is coupled to the pausable mass storage device player. The content player detects a non-viewer initiated event, (e.g., an automatic event such as the receipt of an email with embedded enhanced content), and to assert the pause signal in response thereto. The content player receives content, detects an event, and in response to detecting the event, pauses the content to a presentation device and spools the content onto the mass storage device.

  • Rotating coupling for robotic tool changer with one-way clutch and dual-button handle mechanism
    Patent number: 8500132
    Abstract: A manual robotic tool changer provides a compact, lightweight means to manually selectively couple a robotic tool, such as a surgical tool, to a robot arm. The tool changer includes numerous safety features to prevent inadvertent decoupling of the robotic tool. These include a dual-button handle locking mechanism operative to lock the tool changer closed in the fully coupled position, and requiring simultaneous actuation of both of two latch buttons to unlock; a one-way clutch mechanism that prevents rotation of the coupling mechanism towards the decoupled position, unless the handle is actuated to unlock the tool changer; and a spring biasing the tool changer to an at least partially coupled state when no force is applied to the handle, thus requiring a positive force against the spring, moving the handle to a fully open position, to insert or remove a robotic tool.

  • Hot stretch straightening of high strength ?/? processed titanium
    Patent number: 8499605
    Abstract: A method for straightening a solution treated and aged (STA) titanium alloy form includes heating an STA titanium alloy form to a straightening temperature of at least 25° F. below the age hardening temperature, and applying an elongation tensile stress for a time sufficient to elongate and straighten the form. The elongation tensile stress is at least 20% of the yield stress and not equal to or greater than the yield stress at the straightening temperature. The straightened form deviates from straight by no greater than 0.125 inch over any 5 foot length or shorter length. The straightened form is cooled while simultaneously applying a cooling tensile stress that balances the thermal cooling stress in the titanium alloy form to thereby maintain a deviation from straight of no greater than 0.125 inch over any 5 foot length or shorter length.

  • Symmetrical data signal processing
    Patent number: 8498352
    Abstract: A digital communications receiver includes an input configured to receive, via a communications channel, a received first signal representing a sequence of symbols, each symbol being encoded to be representative of a plurality of data bits. A processor adjusts a magnitude and filters the received signal. An equalizer applies a cyclic prefix restoration to the adjusted and filtered signal, producing a second signal, converts the second signal from time domain to frequency domain to produce a frequency domain signal, and determines a first quantity of values representing a first portion of the symbols by evaluating a relationship of channel values representing characteristics of the communications channel and a second quantity of values representing a portion of the frequency domain signal, the first quantity being smaller than the second quantity.

  • WRITE DATA MASK METHOD AND SYSTEM
    Publication number: 20130166875
    Abstract: In various embodiments, dedicated mask pins are eliminated by sending a data mask on address lines of the interface. A memory controller receives a request for a memory write operation from a memory client and determines the granularity of the write data from a write data mask sent by the client. Granularity, as used herein, indicates a quantity of write data to which each bit of the received write data mask applies. In an embodiment, the memory controller generates a particular write command and a particular write data mask based on the granularity of the write data. The write command generated is typically the most efficient of several write commands available, but embodiments are not so limited. The write command is transmitted on command lines of the interface, and the write data mask is transmitted on address lines of the interface.
