Apparatus is described for imaging a portion of a body of a subject that moves as a result of cyclic activity of a body system of the subject and that also undergoes additional motion. An imaging device acquires a plurality of image frames of the portion. A sensor senses a phase of the cyclic activity of the body system. A control unit generates a stabilized set of image frames of the portion by identifying a given phase of the cyclic activity, and outputting a set of the image frames corresponding to image frames of the portion acquired during the given phase, and by image tracking at least the set of image frames to reduce imaged motion of the portion associated with the additional motion. A display displays the stabilized set of image frames of the portion. Other embodiments are also described.

Apparatus is described for use with a portion of a subject's body that moves as a result of cyclic activity of a body system. An imaging device acquires a plurality of image frames of the portion. A sensor senses a phase of the cyclic activity. A medical tool performs a function with respect to the portion. A control unit generates a stabilized set of image frames of the medical tool disposed within the portion, actuates the tool to perform the function or move, in response to the sensor sensing that the cyclic activity is at a given phase thereof, and inhibits the tool from performing the action or moving in response to the sensor sensing that the cyclic activity is not at the given phase. A display facilitates use of the tool by displaying the stabilized set of image frames. Other embodiments are also described.

It is an object of the present invention to provide techniques for shortening a time required for establishing a correspondence between an electronic shelf label and a product. In an electronic shelf label system (1), in response to receipt of a correspondence cancellation signal in an electronic shelf label (5), a hardware information screen (S2) including a device code (8d) appears. Thus, in the electronic shelf label (5) in an unlinked state, the device code (8d) is kept being displayed. Accordingly, in a subsequent linking process for establishing a correspondence between the electronic shelf label (5) and a product, a process for causing the electronic shelf label (5) to display the device code (8d) is unnecessary, to thereby significantly shorten a time required for establishing a correspondence between the electronic shelf label (5) and a product.

Sunscreen products that do not require the use of organic, ultraviolet-absorbing agents are provided. Effective protection of the skin from ultraviolet light is attained by increasing the amounts of titanium dioxide and zinc oxide. To mask the excessive whiteness that would otherwise result from the oxides, the sunscreen products contain multilayer-type encapsulations containing pigments. Before use, the pigments are enveloped in capsules that muffle the pigments' color. When the sunscreen product is applied to the skin, the capsules break and the pigments are released to counter the excessive whiteness due to titanium dioxide and zinc oxide. Sunscreen product precursors, from which these sunscreen products can be generated by stirring, are also provided. A sunscreen product package contains the sunscreen product precursor and a stirring ball. A method of ultraviolet protection is provided by shaking the sunscreen product package and applying the sunscreen product thus generated to the skin.
