Title: Method and apparatus for interface-progressive video conversion
Inventor: TANG CHE WING
IPC: H04N5/44
Filed: 2001-08-29
Granted: 2010-11-09
Abstract: A method and apparatus for and correcting motion artifacts in interlaced video signal converted for progressive video display. To determine 3-2 pulldown or field motion, a video field is compared to the field prior to the previous field to generate field error. Field errors are generated for five consecutive fields and a local minimum error repeated every five fields indicate the origination of the video material from film source using the 3-2 pulldown process. Upon confirmation of 3-2 pulldown, the video material is modified to correct for the mixing of two film frames into one interlaced video frame by assuring that the two fields of the de-interlaced video frame contain data from the same film frame. Where the video material did not originate from a film source, but pixel motion is detected, the pixel motion is smoothed out by an averaging method. The odd and even fields of the resulting video data are subsequently combined to form a progressive video material.

Abstract: A valve assembly (20) can automatically dispense aerosol content from an aerosol container (22) at predetermined intervals without the use of electri c power. A diaphragm (58) at least partially defines an accumulation chamber (80) that receives aerosol content from the can (22) during an accumulation phase. Once the internal pressure of the accumulation chamber (80) reaches a predetermined threshold, the diaphragm (58) moves axially, carrying with it a leg (62) so as to unseal an outlet, and thereby initiate a spray burst. A pa wl (66) extends from the diaphragm (58), and engages a retention surface (68) t o resist movement of the diaphragm (58) and prolong the accumulation phase. Th e diaphragm (58) assumes its original position when the pressure within the accumulation chamber (80) falls below a threshold pressure.

Granted: 2012-02-07
Abstract: A system in which a packet-sending entity and a packet-receiving entity communicate using parameter signaling channels (SCCH) and also using shared data channels (SDCH) and do so according to a protocol in which when packet data are transmitted over one or more transmission time intervals (TTIs), the communication being such that once a parameter signaling channel is assigned to the packet-receiving entity for communicating a packet, the assigned channel is used in each subsequent TTI as long as there is at least a portion of the packet in the subsequent TTI. When there is, the packet-receiving entity despreads and decodes only one parameter signaling channel for the subsequent TTI along with the data channels. When there is not, the packet-receiving entity despreads all the parameter signaling channels for the subsequent TTI, and may decode some or all of the parameter signaling channels.

Title: Biochemical assay detection in a liquid receptacle using a fiber optic exciter
Inventor: HILLENDAHL JAMES W
IPC: G01N21/64
Filed: 2002-09-24
Granted: 2011-11-29
Abstract: Biochemical assays that are performed in multi-well plates (11) and that utilize a system that supplies excitation light through an optical fiber (21, 22) that transmits light from an excitation light source (14) to the well (12). Emission light produced by the excitation is then collected by a collimating lens (31) and converted to a signal that is compiled for analysis.  The optical fiber (21, 22) and collimating lens (31) can either be on the same side of the receptacle or on opposite sides, i.e., one above the other below.  When the optical fiber and the collimating lens are both on the open side of the receptacle, they are arranged such that the direction of travel of the excitation light and the direction along which the emission light is collected are not coaxial, and preferably both are at an acute angle to the axis normal to the mouth of the receptacle.

Title: Expendable sonobuoy flight kit with aerodynamically assisted sonobuoy separation
Inventor: BILYK DEREK
IPC: F41F5/04
Filed: 2004-05-14
Granted: 2009-12-15
Abstract: The invention is a flight kit that can be retrofitted to existing navy sonobuoys. The invention gives sonobuoys the capability of self-deployment, allowing them to be sent to a location remotely without the use of manned aircraft or recoverable unmanned air vehicles. This capability is advantageous in instances where it is desired to place a sonobuoy in an area hostile or hazardous to manned aircraft. The invention is an attachment of a GPS navigation and control system, wings, control surfaces, and a propulsion system, onto a naval size-A sonobuoy, using the sonobuoy as the central structural load bearing component of the assembly. The invention navigates from a launch point on a ship to a designated position, where the sonobuoy separates from the invention, using the wings' aerodynamic forces to mechanically assist in separating the sonobuoy from the flight kit. The sonobuoy and the flight kit enter the water separately to ensure no interference with the sonobuoy.
