Inventor: TSUKUDA AKIMITSU A
IPC: C08J5/18
Filed: 1997-08-28
Granted: 2000-03-21
Abstract: This invention provides moldings of aromatic polyamide-based resins. At least one surface of the molding can exhibit, under an AFM microscope, a square average roughness of over 1.0nm and a ten-point average roughness of less than 80 nm.

Title: Method for enhancing data transmission in parity based data processing systems.
Inventor: LUCAS GREGG STEVEN
IPC: H03M13/09
Filed: 1998-01-03
Granted: 2000-03-21
Abstract: A data transfer system providing parity uses a method and apparatus for transmitting a data clocking signal in a parity bit location along a data bus to latch an accompanying data byte at a receiving device. A transmitting device, coupled to the receiving device through the data bus, generates a data clock signal and latches the clock signal into the parity bit location of the data bus. The clock signal and data byte are then transmitted along the data bus to the receiving device. The receiving device uses the clock signal to latch the data byte from the data bus. Thus, the data transfer system uses the data clock signal transmitted in the parity bit location of the data bus to validate and synchronize the accompanying data byte at the receiving device.

Title: Method and apparatus for using state determination to control functional elements in digital telephone systems
Inventor: SIH GILBERT C
IPC: H04M1/60
Filed: 1998-05-05
Granted: 1999-09-21
Abstract: A method and apparatus for controlling various functional elements in a digital telephone system using state determination from an echo canceller. An echo canceller is used to evaluate which one of five talk states two speakers are engaged in during a telephone conversation. This state determination information is used to control a tone detector function, a noise suppressor function, an adaptive equalizer function, a transmission mute function, and a vocoder encoder function within a vocoder. During the talk state where the far-end speaker is active and the near-end speaker is inactive, the echo canceller provides a signal which disables background noise estimates from being performed in the noise suppressor and the vocoder encoder. The same signal is used to disable the tone detector and to enable the transmission mute function during this talk state.

The apparatus also includes a detector unit that detects the beam passing through the plume. The apparatus computes a ratio of the second gas to carbon dioxide based upon the first and second detected wavelengths, and this ratio is then multiplied by a predetermined estimation of a concentration of carbon dioxide in the plume.

Title: Dynamic modification of multimedia content
Inventor: MALKIN PETER KENNETH
IPC: H04N21/2668
Filed: 1998-06-08
Granted: 2002-07-21
Abstract: A method and system for manipulating or modifying identifiable objects in a standard broadcast or Internet-based multimedia stream according to a control specification and a content specification. Viewers and/or organizations can independently specify acceptable levels of content on multiple dimensions to satisfy the content specification while minimizing the filtering or blocking to the viewers. A ""fuzz ball"" control specification is provided for masking some portion of a video frame. Several fuzz ball specifications can be overlaid to address multidimensional content specifications or rating systems. The manipulation of the multimedia stream can take place at the client (set-top box or computer), intermediate node, the content server or a combination thereof. Proxy servers can modify content specifications for outgoing requests, enabling organizations to specify intranet-wide policies. Multicasting can be supported by using a single stream delivered to multiple clients, each modifying the video using a different specification. The specification to facilitate modification can be done at different granularity levels: the video, a group of frames, or individual frame level and can also be time-based. Various protocols can be used to provide the content and/or control specification, including the VBI of a standard broadcast, PICS, RTSP and MPEG protocols.

Title: Droppable battery packs
Inventor: CLARKE JOHN EDWARD
IPC: H04W88/02
Filed: 1998-10-08
Granted: 2001-05-01
Abstract: In a battery pack made up of battery cells encased within a housing made up of a stronger outer housing portion and a weaker inner housing portion, the battery cells are secured to the stronger outer housing portion. Advantageously, the relative motion between the battery cells and the stronger of the housing portions that results when prior art battery packs are dropped, and which causes catastrophic failure of the prior art battery packs, is prevented. The battery cells may be secured to the stronger outer housing portion, for example, by gluing the battery cells to the stronger housing portion, attaching the battery cells to the stronger housing portion by using double-sided sticky tape, molding features into the stronger housing portion that immobilize the battery cells adjacent to the stronger housing portion, or providing screw holes through the stronger housing portion so that screws may engage the battery cell or an appendage thereto.

Abstract: A graffiti removing method comprising the steps of: applying a solvent condensation type silicone resin coating composition having water repellency onto a surface of a base material of a structure through a primer layer to form an adhesion-resistant surface layer on the primer layer; applying a releasable coating composition onto the surface layer to form a releasable layer, after graffiti are written onto the surface layer; and releasing the releasable layer from the surface layer after the releasable layer is hardened to thereby remove the graffiti together with the releasable layer from a surface of the surface layer, whereby although graffiti remaining on a surface layer are generally removed by wiping, or the like, not only it is difficult to wipe off graffiti but also the surface layer may be injured.

Title: Device and method for the blowoff of the steam
Inventor: MESETH JOHANN
IPC: G21C15/18
Filed: 1999-02-08
Granted: 2001-08-11
Abstract: In order to prevent the fact that in the nuclear power plant after the blowoff of the steam through a blowoff pipe (12) the cooling liquid (f) would be sucked in the blowoff pipe (12) undesirably high, a ventilating opening (18) is provided, said opening connects through a flow route (18, 20, 22, 40) the gas range (6a, 8a) above the cooling liquid (f), in which the blowoff pipe (12) is immersed, with the interior space (19) of the blowoff pipe (12). The flow route (18, 20, 22, 40) is thus open and free from valves or movable parts, and preferably has different flow resistances for the two opposite directions.

Title: Optical amplifier with wide flat gain dynamic range
Inventor: YADLOWSKY MICHAEL JOHN
IPC: H01S3/06
Filed: 1999-03-30
Granted: 2001-02-11
Abstract: An optical amplifier comprises an optical fiber segment doped with impurity ions such as erbium for providing optical gain for an optical signal propagating in the optical fiber segment. A first source of a first pumping wavelength pumps the ions from a first ground state to a second metastable state. The metastable state decays to the ground state by stimulated emission to provide the optical gain. A second source of a second pumping wavelength pumps the ions from the ground state to a third auxiliary state. The auxiliary state decays to the metastable state. Thus, by controlling the pumping power in one or both pumping wavelengths, it is possible to control the fraction of ions in the metastable state. This in turn permits control of an overall scale factor of the gain spectrum without substantially affecting the shape of the gain spectrum.

Title: Process for preparing alkyl esters of fatty acids from fats and oils
Inventor: TSUTO KEIICHI
IPC: C07C69/30
Filed: 1999-10-04
Granted: 2001-12-01
Abstract: Provided is a process for producing a fatty acid alkylester through a transesterification of triglyceride contained in a fat and oil by causing the fat and oil and an alcohol to react with each other. In this process, the reaction is performed in an atmosphere in which the alcohol is in super-critical state in the absence of a metal alkali catalyst and an acid catalyst. This makes it possible to eliminate a pre-treatment process for esterifying free fatty acids contained in the fat and oil and, in addition, to eliminate or simplify recovering and refining processes of the reaction product by suppressing the by-production of a fatty acid soap.
