Abstract: A cart assembly system for handling laundry in a facility, the system including first and second support structures each having arms extending outwardly therefrom. The arms support drive wheels, which in turn support a tow line extending between the first and second support structures. The system may include a drop cord extending downwardly from the tow line and engaging a slot on a tow cart to attach the tow cart to the tow line. The system may also include a mast extending from the cart to the tow line, the mast supporting a clamp assembly for coupling the cart to the tow line. A controller drives one or both of drive wheels to move the tow line and the cart along the line pathway, where the cart transports laundry throughout the facility.

Abstract: A stopwatch with a 100 base of hours, minutes and seconds will provide direct calculation of the time differential between observed operations. The watch will display 999,999 seconds, or 9999.99 minutes, or 9999.99 hours. The watch will use a display of 6 digits. For accumulating seconds, all digits will be used without a decimal point. Total seconds available will be 999,999. If this total is exceeded, the time will automatically convert to accumulated minutes and tenths and hundreds of minutes. For accumulating minutes and tenths and hundreds of minutes, minutes will be accumulated to 9999.99. If this total is exceeded, the time will automatically convert to hours and tenths and hundreds of hours. A display mode indicator will be used to shift between seconds, minutes, or hours. Changing the mode will convert the time accumulated to the seconds, minutes, or hours selected.

Abstract: Methods and systems for generating pharmacophore models are characterized both by molecular features that are present in the model and features that are defined as absent. Thus, models can be developed that take into account features such as steric bulk that inhibit activity for a specified target as well as features such as functional groups that promote activity. Features that inhibit activity can be identified by comparing known active molecules with known inactive molecules. Features that are present in the inactive molecules but absent in the active molecules can be defined in a pharmacophore model.
