Abstract: 1,145,355. Inverting. LICENTIA PATENTVERWALTUNGS G.m.b.H. 23 March, 1966 [24 March, 1965], No. 12788/66. Heading H2F. In an inverter circuit of the type in which a resonant circuit is maintained in oscillation by triggering a bridge of thyratrons, the disadvantages due to imprecise determination of the voltages across the thyratrons are avoided by centre tapping the capacitor, and connecting it to the centre tap of the power supply. The whole capacitance may be formed by two series connected capacitors (2, 2<SP>1</SP>), the junction of which is connected to the junction of two power sources, Fig. 2 (not shown). Alternatively, the two series connected capacitors (2, 2<SP>1</SP>) may be in shunt with a main capacitor (211) and the tap on the power supply may be provided by two series connected resistors (8, 8<SP>1</SP>) across it, Fig. 3 (not shown). The inductance (4) of the resonant circuit may include a saturable choke (3) in series with it, to disconnect it when the thyratrons are charging the capacitance. Alternatively, the choke may be replaced by a further thyratron.

Title: Concentric lens designs for astigmatic presbyopes.
Inventor: MENEZES EDGAR V
IPC: A61F2/16
Filed: 1996-05-03
Abstract: Concentric lens designs are disclosed for astigmatic presbyopes which comprise at least one surface which has a circular central portion and a plurality of concentric annular rings with at least three separate optical powers corresponding to a prescription for a patient and corresponding to 1) a basic distance spherical prescription Rx, 2) a near add spherical prescription Rx, and 3) a spherical prescription corresponding to the full, or preferably a fraction of the, cylindrical prescription Rx. An astigmatic presbyopic prescription contains an astigmatic correction, normally in the nature of a cylindrical prescription which specifies both the cylindrical optical power and the orientation of the cylindrical axis. The cylindrical prescription is taken into account in the design of the lens, but not with a cylindrical optical surface. Instead, the present invention recognizes that the brain can effectively discriminate between separate competing images by accepting an in-focus image and rejecting an out-of-focus image. Accordingly, a portion of the lens is provided with a spherical surface corresponding to the cylindrical prescription, or more preferably a fraction of the full cylindrical prescription, and the brain is relied upon to discriminate and accept an in-focus image to compensate for the patient's astigmatism.

Title: Method and system for enhancing images using edge orientation
Inventor: LI GUO
IPC: G06T5/20
Filed: 2002-09-02
Granted: 2005-09-07
Abstract: A method and system for enhancing images utilizes the direction of a detected edge within an image block of an input image to selectively smooth or sharpen a pixel of the input image that corresponds to that image block. The direction of a detected edge within the image block is determined by computing the horizontal gradient and the vertical gradient, and then using the ratio of the computed gradients. In an exemplary embodiment, the method and system is designed to exclusively use bit shifting to perform multiplications, rather than using digital signal processing. Consequently, the method and system is suitable for implementation in printer firmware and/or hardware.
