Patents by Inventor Anders Engman

Anders Engman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6926051
    Abstract: The invention is a planing cutter with a cylindrical cutter body (1) with recesses (3) along its enveloping surface. Each recess is delimited by a front wall (4), a rear wall (5) and a bottom (6) and contains a cutting element (7). Each cutting element (7) has a cutting edge (8), a lower edge (9), two lateral edges (10,11), a front face (12) and a rear face (13). One clamping device (2) is also located in each recess. According to the invention each lateral edge (10,11) of the cutting element (7) has a range (14) of grooves. At least one groove in each range interacts with a peg (17,18) protruding from one of the walls (4,5) of the recess (3). The invention also concerns a cutting element (7) for use with the cutter of the invention.

  • Patent number: 5970399
    Abstract: Detection of in-band noise in a radio communications voice channel is provided by mixing a signal having a known frequency into a radio signal containing a voice channel signal in an in-band range, thereby translating the voice channel signal out of the in-band range. The in-band range is thereafter examined for the presence of noise signal energy whose presence can be indicative of in-band noise. Squelching of the voice channel is provided in the event that in-band noise energy exceeds a predetermined threshold.

  • Patent number: 5778027
    Abstract: Methods and systems for determining a cosine (I) or sine (Q) component for the purpose of modulating a digital signal in radiocommunication systems are disclosed. Exemplary embodiments describe how such determinations may be performed using digital signal processing techniques to improve component accuracy, while reducing the amount of processor memory (e.g., DSP memory) used to accomplish this task. Phase information from a sampled signal is used to access one or more tables containing component values, or a combination of a component base values and difference values between consecutive base values. The phase information can be used derive an offset value from the difference values, which offset value is added to a component base value to provide a component value for output. This has the effect of reducing the amount of memory consumed while maintaining high resolution.
