Title: Noise canceller
Inventor: IKEDA SHIGEJI
IPC: H04B3/23
Filed: 1998-01-28
Granted: 2001-05-01
Abstract: A noise canceler of the present invention includes a signal-to-noise power ratio estimator to which a main signal and a reference signal are input. The estimator 10 estimates the sinal-to-noise power ratio of the main signal from the mean power of a desired signal contained in the main siganl and a mean power of a noise signal also contained in the main signal. In addition, the estimator estimates the signal-to-noise power ratio of the reference signal from the mean power of a desired signal contained in the reference signal and the mean power of a noise singal also contained in the reference signal. An adptive filter for estimating the noise signal of the main signal has its step size for coefficient updating controlled in accordance with the estimated signal-to-noise power ratio of the noise signal. On the other hand, an adptive filter for estimating the desired signal of the reference signal has its step size for coefficient updating controlled in accordance with the estimated signal-to-noisepower ratio of the reference signal. Delay circuits are provided for compensating for a delay ascribable to a power averaging procedure which a signal-to-noise power ratio estimator executes to calculate the estimated siganl-to-noise power ratios.

Abstract: A cap for use with a dispensing system. The cap includes a main outer cap and an inner cap. The main outer cap has a central sleeve which receives and seals against a probe. The inner cap moves into and out of a sealing engagement with the central tube as the bottle is raised and lowered over the probe. The seal between the inner cap and the central tube is located on the outside surface of the central tube. The location of the connection between the inner cap and the probe is displaced away from the location of the connection between the inner cap and the sleeve of the main outer cap. This allows the cap to have effective differentials between the forces which are necessary to achieve proper sequencing of the formation of the various seals and connections which occur during use of the cap.

Abstract: A wristworn videoconferencing system is described. In particular, a wearable camera with viewfinder function incorporated into a wristwatch display screen that also electronically simulates the hour hand and minute hand of a traditional wristwatch, results in a device that resembles a fashionably modern timepiece, but which also has the possibly hidden videoconferencing capability. The electronically simulated hands showing the time of day may be overlayed onto the live video of the viewfinder function, or on live video received from a remote site, or a combination of both live video feeds. Pressing a SECRET button causes the electronically displayed clockface with electronically simulated hour hand and minute hand to become opaque and block the live video from being seen. Pressing an OPEN button returns the clockface to a transparent mode, allowing a videoconference to continue.

Abstract: Apparatus and method for monitoring print quality produced by a digital printing mechanism in real-time. Print quality is measured by: generating a background reflectance signal representative of the reflectance of said substrate; scanning the image to generate a post-print reflectance signal; comparing said reflectance signal with said post-print reflectance signal; and, if said post-print reflectance signal is greater than a predetermined fraction of said reflectance signal, generating an output signal indicative of poor quality. In one embodiment of the invention, the output signal is also generated if the post-print reflectance signal is less than a predetermined minimum value. In another embodiment of the invention, the print mechanism is comprised in a postage metering system and the output signal inhibits further printing. In another embodiment of the invention, the background reflectance signal is compared with the post-print reflectance signal to classify the post-print reflectance signal as being satisfactory, unsatisfactory, or doubtful; and if the post-print reflectance signal is doubtful, printing a test pattern and waiting for an operator response; and then if the operator response indicates said test pattern is acceptable, accepting the indicia; and if the operator response indicates the test pattern is unacceptable, rejecting the indicia; and if the operator response indicates the test pattern is acceptable, adjusting the comparison to classify a greater portion of post-print reflectance signals as satisfactory; and if the operator response indicates the test pattern is unacceptable, adjusting the comparison to classify a greater portion of post-print reflectance signals as unsatisfactory.

Abstract: A common metal drum is used in an upside down orientation and has a drum liner system installed through the designated bottom surface thereof. The drum liner system comprises an adapter mounted through the designated bottom surface. The adapter has a relatively large opening through which the liner is easily installed and the drum can be easily inspected and repaired. In another aspect, the adapter and a liner collar share a common thread, and a cover is mountable over this common thread. The thread portion on the liner collar is selectively movable relative to the thread portion on the adapter to cause a locknut effect therebetween and to retain the cover on the adapter and the liner collar. In a further aspect, a drum liner is bonded to the liner collar and is folded inside the liner collar. A hermetic wrapper is stretched around the liner collar and the drum liner. This drum liner package is particularly advantageous for being shippable to a user in an aseptic condition and for being maintainable in this condition prior to use.
