The bulb is configured to house the substance and is exposed at the at least one side aperture to allow the user to apply a pressure to the bulb excrete the substance to the front face of the head portion in response to the pressure being applied to the bulb.

Abstract: A method for determining at least one physiological characteristic of at least one experimental animal in a cage is disclosed. The method may include capturing at least one infrared image of the at least one experimental animal in a band of infrared radiation that is within the range of from about 3 ?m to about 14 ?m in wavelength and capturing at least one visible image of the at least one experimental animal. The method may further include correlating the at least one image and the at least one visible light image and determining the at least one physiological characteristic of the at least one experimental animal based at least in part on the correlation. An apparatus to determine at least one physiological characteristic of at least one experimental animal is also disclosed.

Abstract: Embodiments generally relate to summarizing a photo album in a social network system. In one embodiment, a method includes grouping photos into a plurality of groups of photos, and selecting a plurality of representative photos, where each representative photo represents a respective group from the plurality of groups, where the selecting is based on a quality score of each of the photos, and where each quality score is based on different types of attributes. The method also includes enabling the plurality of representative photos to be shared.
