  • Patent number: 6430761
    Abstract: An improved portable patient transfer device comprising a small wheeled base having a vertically disposed telescoping lifting column extending upwardly therefrom. A patient support means extends from the column to support the patient. A crank, accessible to both patient and attendant, is used to raise and lower the lifting column for transfer between surfaces with different heights, such as beds, wheelchairs, and car seats. The lift my be closed and temporarily attached to a wheelchair for convenient transport with a patient. The lift is small and lightweight and may be easily transported and stored. The lift is further economical to manufacture.

  • Patent number: 5561274
    Abstract: A weight sensor generates a load signal representative of the weight of the object as the object approaches, tips over, and leaves the downstream end of a conveyor. A support mechanism preferably provides balancing of the load upon the weight sensor. The weight of the object is determined from the load signal which is preferably adjusted to compensate for various mechanical effects using signals generated by an inclinometer for measuring the angle of inclination of the conveyor, a mechanism for measuring the speed of the object upon the conveyor, and/or an accelerometer for generating signals characteristic of the vibration of the conveyor.
