Abstract: A device for leveling a surface; the device includes a shaft, a handle-means and a head-assembly. The shaft is selectively retractable, and the head-assembly is foldable to enable compact storage. The device is for personal use by a user in leveling a surface; for example, a sand bunker/sand trap on a golf course. In some versions, the device further includes an attachment-means for attaching the device to a bag.

Abstract: Psychopharmacological properties of new therapeutic drugs and highly heritable behavior patterns of test subjects are identified based on analysis of monitored exploratory movement to identify behavioral signatures. A test subject in a pen is allowed to explore for a period of time, after injecting it with a candidate drug or control vehicle. The test subject's movement is monitored and its locations stored. The locations are analyzed to separate them into behavioral patterns that are defined based on combinations of behavioral feature. Relative frequencies of performing each behavioral pattern are determined. In each pattern, differences between the relative frequencies in the candidate drug and control groups are tested, and only patterns in which this difference is highly significant are retained.
