Abstract: An optical amplification system capable of operating without being affected by the waveform of the incoming optical signal is provided for amplifying the optical signal in its optical waveguide by the effect of stimulated emission of a fluorescent substance induced by pumped light. According to a first aspect of the invention, an optical amplification system turns on its pumping source 8 when there is an optical signal s1 in the optical waveguide 5 whereas the pumping source 8 is kept off as long as no optical signal s1 is found in the optical waveguide 5 so that, when the pumping source 8 is turned on, pumped light from the pumping source 8 is fed to the optical waveguide 5 with a delay of time relative to the incoming optical signal s1. According to a second aspect of the invention, the inside of the optical waveguide 5 is constantly kept under an excited condition so that, when no optical signal s1 is found in the optical waveguide 5, dummy light s3 is fed to the optical waveguide 5, whereas no dummy light s3 is fed to the optical waveguide 5 once an optical signal s1 is introduced to the optical waveguide 5. With such an arrangement, since no optical amplification takes place at the rising edge of an incoming optical signal and hence the operation of optical amplification is not dependent on the waveform of the incoming optical signal, a safe and stable optical amplification system can be established.

Abstract: An ink jet head is disclosed for use with a drop-on demand type printer, and includes an insulating base (240,242), a plurality of elongated barriers (245) projecting upwardly from the base so as to form a plurality of slots (202) between the barriers, a plurality of nozzle holes (203) communicating with the slots, and electrodes formed on the side walls of the elongated barriers. Voltage can be applied to the various barriers through the electrodes in order to cause deflection of the barriers and a corresponding reduction in the cross-sectional area of selected slots, so as to force ink contained in the slots to be jetted through the nozzle holes. In order to provide a uniform ink jet intensity from the outermost slots relative to the inner slots, dummy slots can be formed outwardly of the outermost active slots by providing dummy barriers outwardly of the outermost active barriers. In addition, the nozzle holes are formed in a nozzle plate. The nozzle plate can either be mounted against the ends of the slots, or atop the base. When mounted atop the base, possible breakage of the ends of the barriers is less of a problem. Further, the plurality of barriers can either be mounted to the base by an adhesive, or can be formed integrally with the base. The ink jet head is formed with two bases (240,242), one atop the other, and the barriers of the bases may be polarized in opposite directions.

Abstract: A low air loss patient support system (20) includes a plurality of identical multi-chambered inflatable sacks (34). A restrictive flow hole (64) connects two adjacent chambers (46, 54) disposed predominately to one side of the centerline of the sack, and each side is separately pressurizable under the control of a microprocessor (160) and a plurality of pressure control valves (162) with pressure transducers and a plurality of flow diverter valves (220) for switching between different modes of configuring the manner in which the sacks are pressurized. The system includes a modular manifold (128) for mounting the pressure control valves (162), and a modular support member for mounting the sacks via quick-disconnect couplings and having air flow channels defined therethrough. The support system can rotate or tilt the patient by depressurizing one side of the sacks (34) while increasing the pressurization of the opposite side of the sacks. An end chamber (46) of the depressurized side of each sack remains inflated while the adjacent intermediate chamber (54) becomes progressively deflated during depressurization to permit the end chambers to restrain the patient from sliding off the sacks during tilting. The support system can relieve pressure points between the patient and the sacks while elevating the head and chest of the patient by reconfiguring the diverter valves (162) to connect alternating sacks at the same pressure and periodically decreasing the pressure in one group of sacks while increasing the pressure in another group of sacks alternately to relieve the pressure of and on the patient between the two different groups of sacks depending upon which group is depressurizing and which group is being increased in pressure.

Abstract: A laser scanning device (50) includes a spinner (58), one light spot misalignment detector (68) and a beam misalignment corrector (70). The spinner (58) scans a light beam (54) across a scanning line. The detector (68) is located generally at a beginning of the scanned line and measures an initial misalignment of the light spot in a cross-scanning direction. The corrector (70) dynamically corrects, during scanning along said scanning line, the scanning misalignment of the light beam (54) in accordance with at least the initial misalignment. The corrector includes a pre-positioner which determines an offset for the initial misalignment, a pyramidal error estimator which estimates a first portion of the misalignment due to pyramidal error and a wobble estimator which estimate a second portion of the misalignment caused by wobble. The estimations are summed together and used for correcting the misalignment.
