The present invention relates to cleaning and / or treatment compositions comprising a dye conjugate, and processes of making and using such compositions. Such compositions can provide benefits such as an increase in the whiteness or blackness perception of a situs that is cleaned or treated with such compositions.

Methods and apparatus that provide a hardware abstraction layer (HAL) for a robot are disclosed. A HAL can reside as a software layer or as a firmware layer residing between robot control software and underlying robot hardware and / or an operating system for the hardware. The HAL provides a relatively uniform abstract for aggregates of underlying hardware such that the underlying robotic hardware is transparent to perception and control software, i.e., robot control software. This advantageously permits robot control software to be written in a robot-independent manner. Developers of robot control software are then freed from tedious lower level tasks. Portability is another advantage. For example, the HAL efficiently permits robot control software developed for one robot to be ported to another. In one example, the HAL permits the same navigation algorithm to be ported from a wheeled robot and used on a humanoid legged robot.

A content-based image retrieval (CBIR) system has a front-end that includes a pipeline of one or more dynamically-constructed filters for measuring perceptual similarities between a query image and one or more candidate images retrieved from a back-end comprised of a knowledge base accessed by an inference engine. The images include at least one color set having a set of properties including a number of pixels each having at least one color, a culture color associated with the color set, a mean and variance of the color set, a moment invariant, and a centroid. The filters analyze and compare the set of properties of the query image to the set of properties of the candidate images. Various filters are used, including: a Color Mask filter that identifies identical culture colors in the images, a Color Histogram filter that identifies a distribution of colors in the images, a Color Average filter that performs a similarity comparison on the average of the color sets of the images, a Color Variance filter that performs a similarity comparison on the variances of the color sets of the images, a Spread filter that identifies a spatial concentration of a color in the images, an Elongation filter that identifies a shape of a color in the images, and a Spatial Relationship filter that identifies a spatial relationship between the color sets in the images.

The invention seeks to improve the taking of physical measurements on an industrial product represented by organoleptic perceptions, the method providing a measurement interface that submits descriptors in a relative arrangement such that testers are not influenced by the order in which they appear, regardless of the descriptor and regardless of the field of the descriptor. For this purpose, the invention provides a method of analyzing industrial products in order to characterize them, in order to distinguish between them, and / or in order to modify them so as to improve them, by analyzing the responses of a panel of testers in application of certain descriptors. The method comprises steps consisting in selecting descriptors that are a priori pertinent for determining the organoleptic characteristics of the products; selecting a response mode; providing all of the descriptors simultaneously to the panel of testers on a single occasion and for a determined duration in a measurement interface presenting a center and an input zone for each descriptor, the input zones being distributed uniformly over at least a section of at least one conic about the center of the interface; collecting the responses from each tester as a function of the selected response mode; recording the responses; and analyzing the responses using at least one statistical method.
