| 20090122406 | Optical Image Stabilizer Using Gimballed Prism - An optical image stabilizer is used to compensate for an unwanted movement of an imaging system, such as a camera. The camera has a folded optics system using a triangular prism to fold the optical axis. Two actuators are used to rotate the prism around two axes in order to compensate for the yaw motion and pitch motion of the camera. The prism can be mounted on a gimballed system or joint and two actuators are operatively connected to the gimballed system in order to rotate the prism. Alternatively, the folded optics system uses a mirror to fold the optical axis, and two motors are used to rotate the prism. | 05-14-2009 |
| 20090237793 | ACTIVE-ISOLATION MOUNTS FOR OPTICAL ELEMENTS - Disclosed are, inter alia, optical components that include an optical element (e.g., mirror) and at least three active-isolation mounts mounting the optical element to a frame (e.g., optical barrel or optical frame). An active-isolation mount has a non-contacting actuator connecting a respective location on the optical element to the frame and provides movability of the respective location relative to the frame in at least one direction. At least one displacement sensor is associated with each respective location on the optical element. The displacement sensors are sensitive to displacements of the respective locations in at least one respective direction and reference the displacements to an absolute reference. The actuators and sensors are connected to a servo control loop to provide feedback control. | 09-24-2009 |
| 20100067113 | Apparatus and Method for Displaying Hierarchical Data - A computer readable storage medium includes executable instructions to receive a request for tree node information and apply one or more tree node parameter limits to the request. The tree node parameter limits include a tree node level limit and a sibling node count limit. The computer readable storage medium further includes executable instructions to receive tree node objects corresponding to the tree node parameter limits, add the tree node objects to a dynamically extended tree node data structure and display a first portion of the tree node objects. | 03-18-2010 |
| 20100226010 | Anti-Shaking Optical Element For Optical Imaging Systems - The present invention provides an optical system comprising, at least one lens group for projecting an image on an image sensing means, an optical path being defined between a light entrance of said optical system and said image sensing means, a reflective optical element having convergent or divergent optical power and being located in said optical path, and means for moving the reflective optical element in response to unwanted movement of the imaging system to eliminate or mitigate the negative imaging effect of the said unwanted movement. | 09-09-2010 |
| 20110051243 | PRISM TYPE LENS STRUCTURE - A prism type lens structure is provided. A plurality of piezoelectric elements are mounted to a reflection prism. The deformation of piezoelectric elements corresponding to the applied voltages controls the deflection angle of the reflection prism to compensate the unsteady optical path caused by vibration. Therefore, the image of light signals may be controlled to precisely and steadily focus in an image sensor element to reduce the vibration due to hand shake. | 03-03-2011 |
| 20110181955 | OPTICAL SYSTEM WITH OPTICAL IMAGE STABILIZATION USING A MEMS MIRROR - An optical system with optical image stabilization of the present invention comprises at least one movement determination unit determining a movement of the optical system, a control circuitry generating a movement compensation signal using the movement information of the optical system from the movement determination unit, and a Micro-Electro Mechanical System (MEMS) unit made by microfabrication technology and controlled by the control circuitry with the movement compensation signal | 07-28-2011 |

| 20090002828 | Stabilized mirror system for a handheld laser pointer - A hand-held laser pointer is disclosed wherein the laser beam is isolated from unwanted hand tremor motions of the laser pointer housing. A laser beam is directed toward a pair of passively inertially stabilized mirrors disposed within the housing that are biased to a neutral position by a spring and damper. Both the laser beam that exits the housing and the laser dot appearing at a target are minimally affected by laser jitter associated with hand tremor. | 01-01-2009 |
| 20120019911 | Device for Stabilizing a Light Beam or Images - Device for stabilizing a light beam or images of the type that can be used to stabilize film cameras or light beam emitters, such as a laser emitter or a pulsed laser beam emitter, which includes means for detecting movements in several axes, means for coding the latter and driving means for correcting the unwanted movements of the object to be stabilized ( | 01-26-2012 |
| 20120113514 | Picoprojector with Image Stabilization [Image-Stabilized Projector] - A handheld projector is provided with an image stabilization system that acts to reduce (or even eliminate) unwanted motion of the projected image due to unintended movement of the projector. In certain preferred embodiments, a solid-state motion sensor provides input to an image stabilization system that computes a corrective signal. In embodiments having optical image stabilization, the corrective signal is supplied to a mechanical actuator that moves one or more optical elements within the projector. Other embodiments have electronic image stabilization. In these embodiments, the corrective signal from the image stabilization system is used by the image generator to shift the image so as to compensate for movement of the projector. | 05-10-2012 |
