Patent KR-930702038-A (KR)
IPC: A61M15/00
Filed: 1991-09-10
Abstract: The invention relates to a disposable breath-actuated inhaler comprising a housing forming an air flow path open at both ends, wherein one end forms an air inlet and one end forms an air outlet. The housing includes a compartment for storing a pharmaceutical powder to be inhaled which is located close to the air inlet and covered by a thin foil which seals the compartment in an airtight way. The foil can be removed from the compartment from outside the housing. Additionally, the housing has a constriction adjacent the powder compartment such that a turbulent air stream will be obtained at the constriction upon inhalation which will lift the powder out from the compartment and mix the powder into the air stream.
Patent KR-930703219-A (KR)
IPC: C04B35/06
Filed: 1991-11-14
Abstract: A thermally activated, dry refractory composition and method for the high temperature, dry application of a new refractory lining or the repair of an existing refractory lining on an interior surface of a furnace and the like is disclosed. The composition includes a refractory aggregate and a hydrated material containing chemically bound water of hydration, such as a metasilicate hydrate, which give the composition a self-flowable property, and may include other binders, homogenizers and flowability enhancing agents, such as calcium carbonate and phosphate glass. The refractory composition is placed in a dry state into a hot furnace at a temperature of at least about 500  DEG C, in communication with the surface to be coated. The water of hydration is released at the high temperature causing the composition to become a self-flowable aqueous slurry which coats-out on the surface. Continued exposure to the high temperature causes vaporization of the water with consequent drying and setting of the composition leaving a refractory lining in place on the surface.

Filed: 2011-02-01
Abstract: Video image stabilization provides better performance on a generic platform for computing devices by evaluating available multimedia digital signal processing components, and selecting the available components to utilize according to a hierarchy structure for video stabilization performance for processing parts of the video stabilization. The video stabilization has improved motion vector estimation that employs refinement motion vector searching according to a pyramid block structure relationship starting from a downsampled resolution version of the video frames. The video stabilization also improves global motion transform estimation by performing a random sample consensus approach for processing the local motion vectors, and selection criteria for motion vector reliability. The video stabilization achieves the removal of hand shakiness smoothly by real-time one-pass or off-line two-pass temporal smoothing with error detection and correction.

Title: Storage device and method for providing a partially-encrypted content file to a host device
Inventor: HUTTON HENRY R
IPC: H04L9/14
Filed: 2011-06-30
Abstract: A storage device and method for providing a partially-encrypted content file to a host device are provided. In one embodiment, the storage device retrieves a content file from memory in the storage device and partially-encrypts the content file by encrypting some portions of the content file. The storage device sends the partially-encrypted content file to a host device and informs the host device of which portions of the partially-encrypted content file are encrypted. In one embodiment, the remaining portions of the content file are in clear text form and do not need to be decrypted. Because the host device only needs to decrypt the portions of the content file that are encrypted - and not the entire content file - the host device can decrypt the partially-encrypted content file, even if it does not have the processing power to decrypt a fully-encrypted version. In another embodiment, at least some of the remaining portions of the content file are encrypted with at least one additional key.
