Title: Hartmann wavefront sensor adopting time-division exposure.
Inventor: MA XIAOYU
IPC: H01J9/00
Filed: 2013-03-15
Abstract: A Hartmann wavefront sensor employing different-time exposure comprises a spectroscope, an optical power density measurer, a step-by-step acquisition controller, a microlens array, a CCD (Charge Coupled Device) camera, a center-of-mass calculator and a wavefront restorer, wherein the optical power density measurer measures the optical power density of incident wavefront at first; the step-by-step acquisition controller calculates the exposure time of step-by-step acquisition of the CCD camera to a light spot array according to the characteristics of the optical power density of the incident wavefront and the response sensitivity of the CCD camera, and then controls the center-of-mass calculator to calculate the center of mass of the light spot array step by step after the completion of acquisition; and finally, the wavefront restorer restores the incident wavefront according to the center-of-mass matrix obtained by the center-of-mass calculator. The Hartmann wavefront sensor acquires the array of the light spots at the CCD camera step by step by different exposure time by means of the step-by-step acquisition controller, thereby improving the signal-to-noise ratio of light spot center-of-mass detection in a single sub-aperture when the incident light intensity is uneven, enhancing the accuracy of center-of-mass detection and providing a solution for restoring the incident wavefront with high accuracy under the condition with uneven lighting.

Title: Bed box spring arrangement - has rectangular frame with three transverse support bars and pre-stressed spiral springs
IPC: A47C23/26
Filed: 1974-08-23
Abstract: Rectangular wooden frame has one transverse support bar at equidistant from short sides of frame, and between the first support and the short sides at equidistant on either side another transverse support. Several longitudinal arranged spiral springs fitted inside the wooden frame are prestressed to such an extent that when the springs are not subjected to any load, no force is subjected onto the three transverse rigidly fixed supports. Consequently only when springs are subjected to load do they excert any force upon the transverse support, this means a flat spring formation is maintained and bulges are avoided.

Title: House air distribution and floor heating system - has air passages shaped to use ventilator characteristics fully
IPC: F24D5/04
Filed: 1975-07-11
Abstract: The air distribution system is combined with floor heating, and the air passages are so shaped as to make full use both of the static and the dynamic characteristics of the ventilator. The necessary heat can be dissipated to the rooms by heating the air and floors, and dividing pieces can be provided in the feed pipes, reducing air speed and resistance and increasing the surface area for floor heating, also reducing noise to a great extent. The accumulative effect of the floor can keep the pipes warm for longer than with conventional air heating systems. Thereis no detectable 'on/off' effect, so that continuous ventilation or recirculation takes place.
