    摘要： A plastic item, such as a beverage bottle, conveys two distinct digital watermarks, encoded using two distinct signaling protocols. A first, printed label watermark conveys a retailing payload, including a Global Trade Item Number (GTIN) used by a point-of-sale scanner in a retail store to identify and price the item when presented for checkout. A second, plastic texture watermark conveys a recycling payload, including data identifying the composition of the plastic. The use of two different signaling protocols assures that a point-of-sale scanner will not spend its limited time and computational resources working to decode the recycling watermark, which lacks the data needed for retail checkout. In some embodiments, a recycling apparatus makes advantageous use of both types of watermarks to identify the plastic composition of the item (e.g., relating GTIN to plastic type using an associated database), thereby increasing the fraction of items that are correctly identified for sorting and recycling. A great number of other features and arrangements are also detailed.

    摘要： A surface is laser-etched to convey a 2D machine-readable code pattern. Various strategies are detailed to minimize the etching time. Some strategies include modifying the code pattern to reduce a path length traveled by the laser. Some strategies include modifying the code pattern to make it sub-optimal, i.e., making the code pattern a less-faithful approximation of an ideal code pattern. In some embodiments the etched surface is the surface of a plastic container, and the code pattern conveys information indicating the type of plastic of which the container is manufactured. A variety of other features and arrangements are also detailed.

    摘要： Several (in some cases many dozen) small antennae are integrated into or over a full body suit or clothing. These antennae preferably include an intra-suit or clothing wired connection to one or more small Ultra-Wide-Band (UWB) radios, e.g., in the 3-10 GHz range. In some cases, each antenna connection includes a variable delay, e.g., a few nanoseconds with picoseconds-scale resolution on the delays, thus allowing for the body-suit ensemble to act as a directional phased-array. One claim recites a radio wearable by a human comprising: a phased-array antenna including a plurality of antennae, the array being configured for wearing over or on a human body, the plurality of antennae provided for spatially positioning in multiple different regions over or on the human body; an RF radio; and a controller configured for: i) determining relative spatial position information for antennae within the phased-array antenna; and ii) using at least the relative spatial position information, controlling the radio to produce a directional UWB beam through the phased-array antenna. Another claim includes an antenna having a plurality of metamaterial elements. Of course, other claims and combinations are provided as well.

    摘要： An image capture device, such as a smartphone or point of sale scanner, is adapted for use as an imaging spectrometer, by synchronized pulsing of different LED light sources as different image frames are captured by the image sensor. A particular implementation employs the CIE color matching functions, and/or their orthogonally transformed functions, to enable direct chromaticity capture. These and various other configurations of spectral capture devices are employed to capture spectral images comprised of spectral vectors having multi-dimensions per pixel. These spectral images are processed for use in object identification, classification, and a variety of other applications. Particular applications include produce (e.g., fruit or vegetable) identification. A great variety of other features and arrangements are also detailed.
