    摘要: A mop bucket system includes a liquid-retaining portion and an energy-dissipation device. The liquid-retaining portion is configured to retain liquid. It has a bottom wall portion, a first sidewall portion, a second sidewall portion facing the first sidewall portion, a third sidewall portion, and a fourth sidewall portion facing the third sidewall portion. The liquid-retaining portion permits retained liquid to move in a liquid-movement direction extending from the first sidewall portion toward the second sidewall portion within a higher-momentum region having a width that is approximately 70% of a distance between the third sidewall portion and the fourth sidewall portion. The energy-dissipation device is disposed within the liquid-retaining portion and extends into the higher-momentum region. The energy-dissipation device being configured to inhibit build up of momentum of liquid in the higher-momentum region along at least a portion of the liquid-movement direction by breaking surface tension of the liquid.

    摘要: A safety device, comprising at least one sensor for sensing the presence of an object and a warning system that emits at least one precreated verbal warning message after the sensor senses an object. The warning system includes a control system that allows a user to select at least one of a plurality of precreated verbal warning messages for emission. In another embodiment, a safety device comprises a safety cone, a sensor disposed on the safety cone and that senses an object, and a warning system disposed at the top of the safety cone and that emits at least one warning signal after the sensor senses an object.
