Abstract: A joint-masking device (10) for joints in wall or floor coverings consists of a base profile (12) with a proud ball head (22) and a masking profile strip (14) with a socket pointing downwards which is formed from two co-axial walls  (34,  36)  curved into a circular cylinder. The walls (34, 36) extend around the ball head (22) by more than 180°,  so that the two strips  (12,  14)  can lockingly engage. The masking profile strip (14) can be pivoted to a limited degree, so that inclined positions are possible.

Granted: 2000-01-18
Abstract: An electrosurgical probe comprises a shaft having an electrode array (12) at its distal end and a connector at its proxi-mal end. The array (12) includes a plural-ity of isolated electrode terminals, and an electrosurgical power supply (28) is pro-vided with a multiplicity of independently limited or controlled current sources and a connector.  The electrosurgical probe and the power supply may be connected through their respective connectors so that the independent current sources are con-nected to individual electrode terminals. By applying very high frequency electrical energy to the electrode array, target tissue may be cut or ablated while heat dissipa-tion through low impedance paths, such as blood and normal saline, will be mini-mized.

Title: Decoder for audio signals belonging to compressed and coded audiovisual streams
Inventor: FINOTELLO ANDREA
IPC: G10L19/02
Filed: 1995-12-22
Granted: 1999-07-06
Abstract: A decoder for audio signals belonging to audio-visual streams coded in accordance with standard ISO/IEC 11172 is provided. Said decoder comprises a presentation unit (UP) which is controlled by a first and a second clock signal, depending on the desired sampling rate, and is associated to means (SAV) managing audio-video synchronisation. The latter means start the presentation of output data by comparing a first timing signal (SCR), representative of a system clock signal, and a second timing signal (PTS), representative of a correct instant of data presentation, independently generate the two clock signals (CLK24, CLK22) and correct the signal corresponding to the desiredsampling rate by means of a feedback circuit which c omprises a digital filter (FD).

Abstract: In a control system being provided with a local oscillator (42) and being for controlling a demodulating arrangement (43, 44, and 45) demodulating a desired one of modulated signals in accordance with a demodulating frequency, produced by a sweeping operation of the local oscillator, into a demodulated signal having a unique word and an identification number which are carried by the desired modulated signal, a unique word detecting circuit (47) detects the unique word to produce a unique word detection signal.  A number comparing circuit (48) compares the identification number with a desired one of predetermined numbers to produce a number coincidence signal when the identification number coincides with the desired number.  In response to presence and absence of each of the number coincidence and the unique word detection signals, an oscillator control circuit (49) controls the sweeping operation of the local oscillator.

Title: Modular spill deck
Inventor: FORNEY FRANK G
IPC: B65D90/24
Filed: 1996-04-24
Granted: 1999-10-05
Abstract: A spill deck module of the present invention includes a substantially planar bottom wall, a pair of opposing side walls and a pair of opposing end walls which form an interior chamber.  Each side wall and end wall includes an aperture allowing fluid communication between adjacent modules.  Initially, the side wall and end wall apertures  are closed by a removable sealing assembly.  When a number of modules are desired to be arranged to form a composite spill deck, the sealing assemblies in adjacent modules are removed and replaced with module connection assemblies allowing fluid transfer between adjacent modules.  A deck grating either rests on the bottom surface of the spill deck or rests on top of ribs provided in each module.  The grating forms a continuous spill deck for support of containers of hazardous or non-harzadous liquid materials in various configurations using different combinations of the spill decks.

Abstract: In a transmitter (100), circuitry is employed to automatically calibrate errors in a modulated carrier signal. A generator (320) is activated to generate (510) a low frequency square wave for use as data, which is used to generate a modulating signal from which the modulated carrier signal is generated. The modulated carrier signal is down-converted to an intermediate frequency (IF) signal having a steady state IF signal level. The instantaneous IF signal level is compared (545) to the steady state IF signal level to determine (550) whether the instantaneous IF signal level differs from the steady state IF signal level by greater than a predetermined amount, and, when the instantaneous IF signal level differs from the steady state IF signal level by greater than the predetermined amount, the modulating signal is adjusted (560).

Abstract: A programmable, medical imaging system (250) which incorporates algorithms for enhancing the usability of the system for clinicians is described. With respect to programmability, and in one aspect, the present invention relates to a programmable system which includes a learn mode usable for script generation. In the learn mode, a user can rehearse a sequence of actions and save those actions to be replayed later. In another aspect, the present invention is directed to an algorithm (300) which provides a non-blocking, synchronous interface to an underlying asynchronous architecture. Generally, the algorithm decouples the client-server portion of the application from the synchronous development environment. Using this algorithm (300), a programmer can develop a non-blocking, highly interactive, client-server application without having to resort to asynchronous programming techniques. In yet another aspect, the present invention is directed to an overlap detection and correction algorithm (400) which, in one form is integrated into a review template editor for creating review templates. The overlap detection and correction algorithm (400), in one embodiment, is a one or two boundary rectangular cell overlap detection and correction algorithm (400).

Abstract: A vehicle steering input device includes a fixed housing, a steering input shaftrotatable relative to the housing by a vehicle operator, a hub non-rotatably mounted on the input shaft, a friction member frictionally engaging the hub, a resilient member biased to maintain the friction member in engagement with the hub member, a movable locking ring meshingly coupled to the friction member, and an electromagnet. When the electromagnet is energized it moves the locking ring into meshing engagement with the housing, thus limiting rotation of the friction member and creating an additional friction force which makes it more difficult to rotate the hub and the input shaft. The magnitude of this friction force depends on the bias of the resilient member and is not limited by the strength of the electromagnet.
