Abstract: A laser range finder (LRF) (20) is used to identify an aircraft (12) approaching a gate. The LRF (20) is directed at the aircraft (12), and from the echoes, a profile is derived and compared to known profiles. To distinguish among aircraft (12) with similar profiles, the LRF is directed at a volume in which a feature such as an engine is expected and at another volume in which the engine is not expected. The echoes from the two volumes are used to determine whether the engine is in its expected location. If so, the aircraft (12) is identified as the correct type and is allowed to dock at the gate (16). Otherwise, the aircraft (12) is stopped. The nose height can be used as yet another identifying criterion.

Title: Video compression for multicast environments using spatial scalability and simulcast coding
Inventor: WAN WADE K
IPC: G06T9/00
Filed: 2000-04-10
Granted: 2011-04-05
Abstract: An optimal system for determining whether simulcast coding (400) or spatial scalability coding (100) should be used to encode video for clients with a specific communication link. Operating points (A', B', C') for both simulcast coding and spatial scalability are also determined. Adaptive switching (3130, 3140) is provided, with the operating points and decision boundaries being used to guide the switching to optimize the quality of the higher-resolution data based on a bit allocation to the associated lower-resolution data. A system for determining the point (A', C') of equal quality in both layers of simulcast and spatial scalability coding is also disclosed. The proportion of bits allocated to the base layer to achieve equal quality is essentially independent of the total bit rate for both simulcast and spatial scalability.

Abstract: An ice fishing apparatus for automatically jigging a fishing line. The apparatus has two repeating states, an active state wherein said jigging occurs and an inactive state wherein jigging does not occur. In a preferred embodiment, three optional jigging rates are provided. The duration of the active state for each of the jigging rates is about 10.4 seconds and the duration of the inactive state is about 4.2 seconds. The apparatus is comprised of a housing, an arm pivotally mounted to the housing, an alarm, an electric motor drive unit for rotating the arm upwardly and downwardly to jiggle a fishing line, and an electronic control unit. The electronic control unit controls the periods of the active and inactive states, triggers the alarm, increases battery life and prevents damage to an electric motor. The electronic control unit is a CMOS dual monolithic timing IC circuit. An important feature of the invention is that the tension in the fishing line for activating the alarm system can be selectively preset within a given range. Another feature is that the performance of the apparatus is not affected by water.

Abstract: A light-receiving device incorporating particulate semiconductor devices (solar cells) having a light-to-electricity transducing function or a light-emitting device incorporating particulate semiconductor devices (light-emitting diodes) having an electricity-to-light transducing function. In a solar cell panel shown, solar cells are arrayed on the same plane in rows. Each row of solar cells are parallel interconnected through positive electrode wires and negative electrode wires, and solar cells of adjoining rows are interconnected in series through a connection part. These solar cells connected in parallel and in series are covered with a transparent covering member, thus forming a panel. These solar cells each have externally exposed positive and negative electrode terminals, and therefore the solar cells can be interconnected in parallel, in series, or in parallel and series. When the conductive wires and the covering member are flexible, the device can be deformable. When the solar cells are replaced with light-emitting diodes, the device can be a light emitting one.
