Title: A method and apparatus for transparent, real time reconstruction of corrupted data in a redundant array data storage system
Inventor: BAILEY WILLIAM
IPC: H04N7/173
Filed: 1995-09-25
Abstract: A method and apparatus for providing real time reconstruction of corrupted disk from a redundant array of disks. Each parcel is divided into 'N" blocks of data. An "N+1st" parity block for each parcel is derived based on the content of the "N" blocks of data. The "N" blocks of data and the parity block for each parcel are stored in stripes in the blocks in a redundancy group consisting of "N+1" data storage units. Data is read in "N+1" whole block reads (600, 610, 620). If none of the received blocks are parity then the data is copied to a buffer (630, 650). If parity exists in some of the received blocks, then if the "N+1" block has been received the data is copied to a buffer; if not then XOR blocks are received (630, 635, 640, 650).

Title: Operation of a radiotelephone in a synchronous extended standby mode for conserving battery power
Inventor: KIVARI RAIMO K
IPC: H04B1/16
Filed: 1996-05-27
Abstract: A method and system for operating a radiotelephone at reduced power provides for a deenergization of a receiver of the radiotelephone wherein the receiver, during periods of activation, receives a sequence of messages of a control channel, each message having a synchronization portion and a data portion which follows the synchronization portion. Included within the radiotelephone is signal processing circuitry synchronized by a synchronization portion of an individual one of the messages to permit a reading of data of the data portion of an individual one of the messages. A digital phase locked loop (DPLL) with phase adjustment capability enables operation of synchronization circuitry and the data reading circuitry.   Electronic circuitry within  the  DPLL  provides  for  inhibiting  the  phase adjustment  function  in  response  to  the  command  of  a controller of the radiotelephone subsequent to a reading of data and concurrently with a termination of power to the receiver.  The phase adjustment function is enabled upon reactivation of the receiver and operation of the data reading circuitry for reading data of a subsequent message.

Abstract: A rare earth element-doped multiple-core optical fiber has an outer cladding layer and a plurality of cores each covered with a primary cladding layer. The cores are positioned substantially on a central axis of the outer cladding layer and separated with a predetermined spacing S from each other by the primary cladding layer. The outer cladding layer is made of SiO2, or SiO2 to which a dopant like F, Ge, etc. is added. The primary cladding layer is made of SiO2 doped with Er, or SiO2 doped with Er and F together and formed to have a predetermined thickness of 1.0µm - 1.5µm to form the predetermined spacing S. The soot glass rods for cores and primary cladding layers are immersed in an Er-compound solution, then picked up, dried and consolidated to form Er-Al co-doped SiO2 - GeO2 transparent glass rods. The glass rods are inserted into a quartz tube and collapsed by heat to fabricate an optical fiber preform rod, then heated to be drawn to provide an Er-doped multiple-core optical fiber.

IPC: B01D53/86
Filed: 1996-12-04
Abstract: A method is described for cleaning exhaust air containing pollutants, especiallygaseous hydrocarbon emissions in an exhaust duct, using a catalyst and a UV radiation raising the energy level of the hydrocarbons. The invention is characterized in that the exhaust air is exposed in a first section of the air duct to UV-C radiation of a wavelength of below 300 nm, preferably of about 254 nm, which causes an excitation of the hydrocarbons to higher energy levels, and also to a UV-C radiation of a wavelength preferably of about 185 nm, which additionally causes the formation of ozone, and of molecular oxygen and radicals from the ozone, while a partial oxidation of the hydrocarbon molecules takes place in the gas phase, and in that in a following second section of the air duct a catalytic oxidation of the hydrocarbon molecules is performed at the inner surface of a porous support material, the hydrocarbon molecules being absorbed, then oxidized on the active surface by the additionally formed ozone and removed from the surface of the catalyst in the form of H2O and CO2 as reaction products.

Title: Method and apparatus of facial image conversion by interpolation/extrapolation for plurality of facial expression components representing facial image information
Inventor: CHANDRASIRI NAIWALA PATHIRANNE
IPC: G06T13/00
Filed: 1997-08-28
Abstract: An input/output control mechanism receives facial image information of different facial expressions of a plurality of human beings to provide control so that a normalization processing mechanism normalizes each facial image information. A facial expression generation mechanism converts the normalized facial image information into facial expression components, and averages the facial expression components for each facial expression to store the same as average facial expression components. The input/output control mechanism has the facial expression component converted by the facial expression generation mechanism after the applied facial image information is normalized. The facial expression generation mechanism converts the facial expression components of the applied facial image information according to a difference between an average facial expression component corresponding to a facial expression of applied facial image information and an average facial expression component of a specified facial expression. Synthesized facial image information is generated from the converted synthesized facial expression component.
