Abstract: A system and method for measuring the weight of patients in a wheelchair are disclosed, including two portable weight measurement devices, wherein the devices measure the weight imposed on two wheels of a four wheel wheelchair, and a receiver that accepts weight measurement data from the portable weight measurement devices. The weight data exchanged between the two portable weight measurement devices and/or with the receiver may be transported over wireless connections.

Abstract: A stretcher supporter, and a method of balancing a stretcher supporter for a patient lifting device, are disclosed. The stretcher supporter includes an open frame, wherein said open frame provides for secure attachment of a stretcher to said open frame and an adjustable lifting point connected to said open frame, wherein said adjustable lifting point suspends said open frame and rotatably shifts to substantially balance said stretcher respective to said open frame. The method of balancing a stretcher supporter for a patient lifting device, includes the steps of securely attaching a stretcher to an open frame of said stretcher supporter and adjusting a lifting point connected to said open frame, wherein said adjusting a lifting point suspends said open frame and linearly and rotatably shifts to substantially balance said stretcher respective to said open frame.

Abstract: A high speed fluorescent emission imaging digital microscope has an Argon-Ion UV laser illumination source and a high speed optical filtering wheel in the illumination path to alternately select between two UV illumination wavelengths to produce fluorescent emission images at each UV wavelength. A dichroic reflector directs emission images along an image path and an galvanometer rotatable mirror exposes each image on a predetermined area of a CCD. A computer controls the rotatable mirror in response to exposure timing information from the filtering wheel. An objective lens is focused on the specimen for producing an image from a particular focal plane of the specimen. The objective lens is mounted on a counterweighted piezoelectric objective translator for changing the focal plane of the specimen image in response to control signals from the electronic processor.

Abstract: A two PROM coherent optical processing system under computer control provides zoom of the input object, rotation of the filter PROM relative to Fourier transform of the coherent light image, serial painting of the spatial filter on the filter PROM using a digitally controlled laser scanner, and greater operator control of the filtered image using a digital video processor and the associated computer.
