Method, modules and a system formed by connecting the modules for controlling payloads are disclosed. An activation signal is propagated in the system from a module to the modules connected to it. Upon receiving an activation signal, the module (after a pre-set or random delay) activates a payload associated with it, and transmits the activation signal (after another pre-set or random delay) to one or more modules connected to it. The system is initiated by a master module including a user activated switch producing the activation signal. The activation signal can be propagated in the system in one direction from the master to the last module, or carried bi-directionally allowing two way propagation, using a module which revert the direction of the activation signal propagation direction. A module may be individually powered by an internal power source such as a battery, or connected to external power source such as AC power. The system may use remote powering wherein few or all of the modules are powered from the same power source connected to the system in a single point. The power may be carried over dedicated wires or concurrently with the conductors carrying the activation signal. The payload may be a visual or an audible signaling device, and can be integrated within a module or external to it. The payload may be powered by a module or using a dedicated power source, and can involve randomness associated with its activation such as the delay, payload control or payload activation.

A transmission type color calibration chart includes a transparent substrate and a color bar group formed on the transparent substrate, wherein the color bar group is constituted by color bars of a plurality of colors containing at least a first color and a second color arranged in a pattern in no particular order, coordinate points of the first color are within a region encompassed by the four points (0.351, 0.649), (0.547, 0.453), (0.380, 0.506) and (0.433, 0.464) on an xy chromaticity diagram, coordinate points of the second color are within a region encompassed by the four points (0.125, 0.489), (0.112, 0.229), (0.270, 0.407) and (0.224, 0.242) on an xy chromaticity diagram, and the transmission spectrum of the first color's color bar and the transmission spectrum of the second color's color bar have peak tops that are respectively separated.

The Swatch is an Educational Beauty Apparatus providing a fabric material that is attached to a synthetic or natural hair extension. The hair extension attached to the fabric is not used as a hair extension to alter appearance but used as a guide in the color consultation process. Each Swatch will vary in different shades of hair color, shades of highlights and low-lights, and act as the precise foil placement. The Swatch will be placed over the guests' head using a wig cap or plastic cap for sanitation purposes. The Swatch can be hand washed and air dried with no heat.

A method of camouflaging a tonal imperfection comprising the steps of: identifying a skin tone of a user comprising a tonal imperfection; instructing the user to select a pigmented cosmetic composition adapted to camouflage the tonal imperfection based on the user's skin tone; selecting the pigmented cosmetic composition; and selectively targeting and depositing the pigmented cosmetic composition substantially only onto the tonal imperfection; wherein the pigmented cosmetic composition comprises an average composition L* value of about 10 to about 40 units greater than an average skin L* value of the user. The pigmented cosmetic composition can comprise a particular set of L*C*h* values such that when deposited onto tonal imperfections, it can result in natural, flawless looking skin, while still remaining substantially undetectable to the naked eye.

A system is disclosed that obtains an image of an apparel item and text describing the apparel item. The system also determines descriptive metadata of the apparel item by extracting information from the text. Further, the system further determines categorization metadata of the apparel item by analyzing the image. Additionally, the system stores the image, the descriptive metadata, and the categorization metadata in a virtual closet. Moreover, the system provides a recommendation of an outfit from a stylist to a user based on the virtual closet.

A system and method for assisted-learning with a portable computing device that includes a color detection mode and a game mode.

A paint color analysis station has a main body with a front exterior surface and a rear exterior surface. A paint sampling portion and a drying portion are disposed on the front exterior surface of the main body. The paint sampling portion has a paint sampling surface extending outwardly from the front exterior surface of the main body at an angle that is less than 90 degrees. The drying portion has a main body and an overhang disposed directly above the paint sampling portion. The overhang includes an opening configured to receive a drying device. At least one hanging portion and at least one storage portion are also disposed on the paint color analysis station. The at least one hanging portion and the at least one storage portion are configured to conveniently organize and house various paint analysis tools and accessories when not in operation.

A process of toilet training a subject to encourage urination in a toilet. Urease and color changing first pH indicator are introduced into water a toilet bowl of the toilet. In the presence of urine in the water the urease reacts with the urine to create a by-product that causes the color changing first pH indicator to change to a first color at a first pH thereby encouraging the subject to urinate in the toilet. A composition is provided that includes urease, color changing first pH indicator an excipient comprising citric acid, a binder, or a combination thereof. A kit is provided for the composition, a container for the composition, and instructions for using the composition during toilet training.
