Granted: 2006-08-15
Abstract: A method and apparatus for mixing liquids or liquids (9) with particles (8) without the aeration of the liquid. The liquid and/or particles (8) opposed in a vessel (2) having an upper end (4) and a lower end (5) and a containing wall (3) extending between the upper and lower ends. A mechanical rotating means (6) disposed adjacent the upper end (4) and submerged in the liquid (9) is used to induce a rotational flow directed radially outward from a central region of the vessel towards the containing wall (3) to establish a swirling flow. The flow is characterised by an outer annular region (11) of moderate rotational flow adjacent the containing wall (3) moving from the upper end (4) toward the lower end (5), an inward flow adjacent the lower end of the vessel (2) and an inner core (12) of rotational flow about the central region of the vessel (2). The inner core flow (12) moves from the lower end (5) toward the upper end (4) and extends substantially from adjacent the lower end (5) of the vessel to the mechanical rotating means (6).

Title: Frame-based audio coding with additional filterbank to suppress aliasing artifacts at frame boundaries
Inventor: FIELDER LOUIS DUNN
IPC: G10L19/022
Filed: 1998-10-01
Granted: 2005-08-02
Abstract: Several audio signal processing techniques may be used in various combinatio ns to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain - control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or forms of TDAC transforms are used to suppress aliasing artifacts on either side of a splice. In yet anoth er technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. I n a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, fo r example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.

Abstract: A roller degradation monitor device monitors the diameter of escalator rollers during operation of the escalator. A cam plate is mounted proximate the roller track for sequential contact with the upper circumference of rollers as they travel along the track. The vertical displacement of the cam plate is monitored by a proximity switch or sensor, differences in cam plate practice from an established baseline signifying variations in roller diameter. The output of the proximity switch or sensor provides a continuous measure of wear and decrease in diameter of the rollers. When the wear exceeds a predetermined value an alarm can be actuated.

Abstract: A door or other entryway component of synthetic resin composite construction and closely resembling the appearance of stained real wood. Skin portions of doors and other structures have a surface layer of clear gel coat resin molded to include the texture of a wood grain surface. A subsurface layer adjacent the clear gel coat layer is of pigmented gel coat resin. A structural support layer of the skin is of reinforced resin. Skins of a door or similar article are mounted on frames, and dense micro porous resin foam is provided between the skins to form a solid structure such as a door. Moldings retaining glass panels in openings defined in the door or similar structure are attached to the skins by adhesively fastening the moldings to the skins. Fasteners mounted in the moldings so that there are no plugged holes in the exterior surfaces of the moldings are used to locate the moldings properly with respect to the skins by inserting the fasteners into predrilled holes in the skins. The assembled doors and other structures can be finished by staining and coating with a finish system such as a urethane varnish to provide an appearance closely resembling real wood.

Abstract: The present invention relates to a wireless home automation system having a controller for controlling a broad variety of functions via two ways communication with a plurality of devices. More specifically, the invention relates to an improved and flexible way of routing signals from a controller to a device which includes the building of various tables such as routing tables. The improved and flexible way of routing allows the user to reach any device within the network with a high reliability. According to the invention, a processing unit of a controller is adapted to instruct a first device to discover other devices within its range by transmitting a signal comprising a device table holding device identifiers of devices controlled by the controller. The devices in the system are adapted to, upon instruction, perform a discovery of other devices within its range by transmitting discovery signals addressed to each device in the device table received from the controller. The devices save the identifiers of the device which acknowledges the reception of the discovery signals in a list indicating which devices of the device table it can reach and which it can not reach. The controller can at any time collect the saved list from a device to build a routing table.

Title: Feedback compensation detector for a direct conversion transmitter
Inventor: NIELSEN JORGEN S
IPC: H04B1/04
Filed: 2002-05-15
Granted: 2004-11-23
Abstract: A feedback compensation detector for a direct conversion transmitter includes a baseband processor, a direct up-converter, an antenna, and an impairment detection and compensation feedback circuit. The baseband processor generates an in-phase (I) baseband signal and a duadrature-phase (Q) baseband signal. The direct up-converter is coupled to the baseband processor, and combines the I and Q baseband signals with an RF carrier signal to generate an RF output signal. The antenna is coupled to the direct up-converter, and transmits the RF output signal. The impairment detection and compensation feedback circuit is coupled to the RF output signal and the I and Q baseband signals. The impairment detection and compensation feedback circuit down-converts the RF output signal to generate an intermediate frequency (IF) signal, measures as least one signal impairment in the IF signal, and pre-distorts the I and Q baseband signals to compensate for the measured signal impairment.
