Abstract: An electrophoretic record that includes at least one gel separation is mounted for motion laterally of the separation record. A light source is positioned to illuminate at least a portion of the record, and a linear array camera is positioned to have a field of view of the illuminated portion of the record and orthogonal to the direction of record motion. The elements of the linear array are scanned at increments of motion of the record across the field of view to develop a series of signals corresponding to intensity of light at each element at each scan increment.

Abstract: A spectrmeter radiation transmission system is disclosed which permits concurrent availability of numerous alternative accessory devices by conserving radiation throughput. Parabolic reflectors are used to provide alternating collimated and confocal segments of radiation, thereby largely eliminating the problem of vignetting (i.e., loss of radiation throughput due to beam size expansion). Modular enclosure elements are provided, inside which the radiation path travels between the parabolic reflectors.

Abstract: A wearable device includes a testing portion, the testing portion includes receiving space, a bottom surface defining an opening, an opposite top surface, and a first side surface defining a slot. A white light source is received in the receiving space. A wearable portion of the device is secured to the testing portion and the wearable portion can be placed around a terminal device comprising a camera. The opening faces the camera when the wearable portion is around the terminal device, allowing the camera to capture a standard image of the white light, and capture a wet image of a test paper imbued with user bio-matter when the test paper is inserted into the slot. A biological information of the user, as an indicator of health, is calculated according to a color comparison between the wet image and the standard image.
