A base/navigator framework is presented to correct unknown clock biases of the LTE eNodeBs. In this framework, the base receiver is placed outdoors, has knowledge of its own position, and makes pseudorange measurements to eNodeBs in the environment whose positions are known. The base transmits these pseudoranges to the indoor navigating receiver, which is also making pseudorange measurements to the same eNodeBs. The navigating receiver differences the base and navigator pseudoranges. The navigator receiver is equipped with an extended Kalman filter (EKF) to fuse LTE and IMU measurements in a tightly-coupled fashion and estimate navigating receiver states. | 2021-04-15 |

20210109329 | PROJECTION DEVICE AND PROJECTION SYSTEM INCLUDING THE SAME - A device for projecting a test pattern for evaluating the image-capturing properties of a lens module includes a light emitting assembly. The light emitting assembly includes a light emitter and a patterning plate on the light emitter. The patterning plate includes a first surface facing the light emitter and a second surface opposite to the first surface. The second surface is concave and defines a patterning groove. The light from the light emitter passes through the patterning groove to form an original pattern for testing, the display of a test pattern being instantly selectable and displayable. | 2021-04-15 |
20210109330 | ZOOM LENS AND IMAGE PICKUP APPARATUS - A zoom lens consists of in order from an object side to an image side: a first lens unit having a positive refractive power and configured not to move for zooming; three or four moving lens units configured to move in zooming: an aperture stop: and one or two rear lens units including a rear lens unit closest to the object side and configured not to move for zooming. An interval between each pair of adjacent lens units is changed in zooming. The three or four moving lens units include a moving lens unit having a negative refractive power. The three or four moving lens units include a rear positive lens unit closest to the image side and having a positive refractive power. The first lens unit includes three positive lenses. Conditional expressions are satisfied by the zoom lens. | 2021-04-15 |
20210109331 | VARIABLE MAGNIFICATION OPTICAL SYSTEM, OPTICAL APPARATUS, AND METHOD FOR PRODUCING VARIABLE MAGNIFICATION OPTICAL SYSTEM - A variable magnification optical system comprising, in order from an object side, a first lens group having negative refractive power, a first intermediate lens group having positive refractive power, a second intermediate lens group having negative refractive power and a rear lens group; upon varying a magnification from a wide angle end state to a telephoto end state, a distance between the first lens group and the first intermediate lens group being varied, a distance between the first intermediate lens group and the second intermediate lens group being varied, and a distance between the second intermediate lens group and the rear lens group being varied; the rear lens group comprising at least one focusing lens group which is moved upon carrying out focusing from an infinitely distant object to a closely distant object and at least one lens component at an image side of the most image side focusing lens group in the focusing lens groups; and predetermined conditional expressions being satisfied, thereby the focusing lens group(s) being reduced in weight. | 2021-04-15 |
20210109332 | OPTICAL SYSTEM FOR AN LED WASH LUMINAIRE - An optical system for an LED wash luminaire employing an lens with a first Fresnel functional surface and a second functional surface comprised of a plurality of out of focus microlenses in bands of different focal lengths in combination with specially shaped reflector(s) to achieve a more even light distribution on a surface area with a wide range of distances from the luminaire. | 2021-04-15 |
