Abstract: A light-monitoring apparatus includes a power source, a light detector, a computer processor coupled with the power source and in communication with the light detector and configured to receive and record light exposure detected by the light detector, an output device coupled with the computer processor, and a computer-readable medium coupled with the computer processor and storing instruction code for summing the recorded light exposure from the computer processor over time and communicating a signal to the output device to generate and communicate a signal indicating that a cumulative threshold light exposure for achieving a health benefit has been reached. The apparatus can accordingly be used by an individual to monitor cumulative light exposure from both natural and artificial sources, e.g., in the treatment of seasonal or non-seasonal depression.

Abstract: The invention is directed to improving the disinfection of dental impressions following removal from the patient's mouth and before entering the dental laboratory to prevent contamination. It involves the use of a pH-adjusted hypochlorite solution, which is highly effective in killing microorganisms, and also relatively inexpensive. Using the solution of the instant invention for disinfection causes no damage to the impression, no loss of accuracy, and does not destroy the details on the impression surface.

Abstract: A beam deflection system is provided with electrical circuitry for adaptively correcting the deflection of a beam of radiant energy in a scanning system incorporating a rotating scanning mirror to compensate for misalignment in facets of the mirror. With the use of an acousto-optic modulator providing a deflected beam at an angle dependent on the frequency of an acoustic drive signal, the orientation of the beam can be altered to compensate for the misaligned facets by varying the acoustic frequency. A sensor and bridge circuit signal the position of a beam scan. A memory stores the value of the frequency for scans by each facet, the value being altered with each scan to optimize the frequency. A drift compensation circuit provides for an averaging of the parameter values, and provides a voltage to adjust the balance of the bridge to drive the average value towards a reference value.

Abstract: There is disclosed a pharmaceutical composition for therapeutic use comprising an immune globulin and fibronectin in amounts sufficient to produce an opsonic activity in the composition that is greater than the additive opsonic activity of the individual agents or in amounts sufficient to produce a phagocytosis of infectious agents greater than the additive effect from fibronectin and immune globulin alone.
