Patent number: 8988567Abstract: A single array of pixels is used to obtain a plurality of different images at different levels of admitted exposure light from a common source level of exposure light. More particularly, first and second matrices of light-admitting elements are deployed in a single camera and disposed relative to focal lens light in front of corresponding first and second matrices of light-sensitive image sensors that are arrayed in a singular focal plane array in the camera and react equally to equal levels of color image information. The respective matrices of light-admitting elements transmit color image information from exposed focal lens light at different levels of brightness to their corresponding matrices of light-sensitive image sensors, wherein first and second images are acquired at the respective different levels of brightness from the respective matrices of the image sensors, and pixel data from the images combined to produce an HDR image.Type: GrantFiled: March 27, 2013Date of Patent: March 24, 2015Assignee: International Business Machines CorporationInventors: Derek Kwan, Angela Y.

Publication number: 20040040093Abstract: Weed-Grabber a multifunction hand operated garden tool device equipped with semi-automatic gabbing clamp mechanism positioned over a 6 inches long cutting blade for deep ground penetration sporting wide T-shaped cutting blade tip to cut and grab all kinds of weeds from small inch size buds to several feet full-grown plants with some roots several inches thick and vines. Long cutting blade length provides means to work the soil and also by simple twisting it can pulverize weed roots left in dirt after each cutting as well. Motion of the Clamp is derived either from a manual release-handle and/or as the cutting blade penetrates the ground the clamp opens and it closes when the blade comes out. And multiple weeds can be removed at once plus it comes with attachment tool heads. Grab-clamp design of this tool allows picking up loose yard debris as big as an army boot and handy for reaching into flower beds.Type: ApplicationFiled: September 3, 2002Publication date: March 4, 2004Inventor: Gregory Y.C.

Patent number: 6251782Abstract: A method for preparing small area parallel lapping specimens by a focused ion beam technique is disclosed in which a multiple-staged ion beam milling process is used to prepare a specimen for microscopic examination. The method may be carried out by first providing a high current ion beam for removal of a top surface of a specimen exposing a surface that immediately covers the characteristic feature to be examined to define a small window area that contains the characteristic feature. The present invention novel method may further be combined with a wet etching step after the ion beam milling process is completed. In the wet etching step, a three dimensional surface containing the characteristic feature to be examined is revealed which can then be observed under a scanning electron microscope.Type: GrantFiled: July 23, 1999Date of Patent: June 26, 2001Assignee: Vanguard International Semiconductor CorporationInventors: Angela Y.C.

Patent number: 5474025Abstract: Bird cage furniture comprises a number of interconnecting parts including ladder sections 10 and 11, apertured nodal bodies 12, 14, 16, 17, 18 and 19, linking members 20, feet 22, 23, 24 and 25, and a feeding trough 26. The parts are readily assembled into the configuration shown, or other configurations, by entering and gripping ends of the ladder sections, the linking members and tops of the feet into different apertures in the bodies 12 to 19. The feet 22 and 23 have their bases gripped between adjacent wires of a wire mesh wall of a cage. The furniture can be readily disassembled for removing its parts from the cage, for cleaning and so on.Type: GrantFiled: October 13, 1994Date of Patent: December 12, 1995Assignee: Alliance Pet Supply Company LimitedInventor: Ivy Y.

Patent number: 4943796Abstract: The structure of a rear view mirror mounted reversing distance sensor for automobiles having a housing, a cover, a spring and a retaining bracket. The housing and the cover together form a hollow, L-shaped structure when assembled. The housing has an upright part and a base. A channel is formed on the central portion of one lateral surface, opposite and parallel to the cover, of the upright part. The channel receives the retaining bracket at the uppermost portion of the channel, which also receives a first pad. A second pad is disposed over the entire top surface of the base. The retaining bracket is a flat sheet of metal bent to form an L-shape. The first leg, parallel to the cover, of the retaining bracket is formed a tab with a first hole therethrough for securing of one end of the spring.Type: GrantFiled: June 9, 1989Date of Patent: July 24, 1990Inventor: Y.

Patent number: 4887244Abstract: Method of interpolating additional seismic traces between existing seismic traces obtained during the exploration of a subsurface formation. Seismic traces are recorded upon a datum surface in accordance with standard seismic data acquistion methods. Forward and backward wave equation datuming of the data set at the same velocity estimates new measurements for originally acquired data deemed unsatisfactory by propagating measured seismic traces to a fictitious datum plane using wave theory to create a second set of seismic traces and datuming the second set of seismic traces, again using wave theory, back to the original datum plane to create a third set of seismic traces. The third set of seismic traces will include new seismic traces to be used in place of the originally acquired unsatisfactory data.Type: GrantFiled: June 28, 1988Date of Patent: December 12, 1989Assignee: Mobil Oil CorporationInventors: Mark E.
