Title: Voice internet transmission system
Inventor: RADULOVIC ALEX
IPC: H04M3/38
Filed: 1997-02-05
Granted: 2006-10-10
Abstract: A voice Internet transmission system which enables a person to have a conversation via the Internet (16) without having to use a computer at either end of the conversation, and without incurring long distance telephone charges regardless of the distance between those having the conversation. In a preferred embodiment, the apparatus consists of two non-Internet capable devices being enabled to connect to the Internet (16) and either in duplex or simplex mode transmit packets of Internet formatted data comprising digitized, compressed and encrypted conversation between the devices. In other words, a person can pick up an ordinary telephone (30) and converse with another person, regardlesss of the distance between them, without incurring long distance telephone charges. No special telephone is required, nor is a computer running a special software. The apparatus which makes this possible is a system of Internet access nodes or VoiceEngines (32, 34). These local Internet VoiceEngines (32, 34) provide digitized, compressed, and encrypted duplex or simplex Internet voice/sound communication services.

Abstract: A raised pavement marker (10) includes a rigid reflector assembly (24) that supports two retroreflectors (26). The reflector assembly (24) is resiliently mounted over a base (14) by a resilient membrane (18), which is secured to the base (14) at the membrane's outer edge (20). When a vehicle contacts the reflector housing (25), downward forces supplied by the vehicle to the reflector housing (25) deform the membrane, which allows the reflector housing to move downwardly to pavement level. After the vehicle has passed, the resilience of the membrane (18) restores the reflector assembly (24) to its raised position. Methods for installing and removing the pavement marker (10) are disclosed.

Title: Control of diarylalkane by-product formation in alkylation of aromatics by olefins using zeolite beta catalyst
Inventor: GAJDA GREGORY J
IPC: C07C15/16
Filed: 1999-03-01
Granted: 2008-07-08
Abstract: The amount of an undesired diarylalkane by-product formed in an alkylation reaction using a zeolite beta catalyst in which a feed aromatic reacts with an olefin is reduced by using an alkylaromatic diluent in an amount such that the ratio of phenyl group per alkyl group corresponding to the olefin reactant entering the reactor is held in the range 0.75:1 to 25:1 and the concentration of the olefin entering the reaction is less than an amount calculated by dividing MW O by the sum of 6.17 MW A and MW O where MW O =  molecular weight of the olefin and MW AA = molecular weight of the feed aromatic.

Abstract: L'invention concerne un procédé pour produire des séries d'impulsions de tension destinées à faire fonctionner des lampes à décharge (8) au moyen d'une décharge pulsée, diélectriquement inhibée, selon lequel une partie des valeurs de pointe d'impulsion nécessaires est remplacée par une composante tension continue de décalage (UDC(t)). Cela a pour avantage le fait que lors de la production des séries d'impulsions de tension (UP(t)), il se produit des interférences électromagnétiques proportionnellement plus faibles. Il est en outre prévu qu'une partie de la puissance effective électrique injectée pour produire la décharge principalement pendant la durée des impulsions de tension soit injectée sur la base de la tension continue de décalage (UDC(t)). Dans un circuit, il est prévu de monter en série, à cet effet, un cicuit d'impulsion (1) et un circuit à tension continue (2), le circuit d'impulsion (1) pouvant être dimensionné pour avoir, si l'on compare avec l'état de la technique, une puissance plus faible.

IPC: A61N1/365
Filed: 1998-09-11
Granted: 2004-03-09
Abstract: An implantable sensor/stimulator is connectable to a controller using just two conductors, which two conductors carry both operating power and data (data commands and/or measured data) between the sensor/stimulator and control circuit. Each sensor/stimulator may be serially connected to another sensor/stimulator, again using only two conductors, thereby allowing a "daisy chain" of such sensors/stimulators to be formed. Each sensor/stimulator in the daisy chain is individually addressable by the control circuit. Input data is sent to the sensors over the two conductors using a phase-modulated biphasic modulation scheme, which scheme also provides operating power for each sensor/stimulator connected to the two conductors. Output data is sent from the sensors to the controller over the same two conductors using a pulse-position presence/absence modulation scheme. The data transmisssion schemes provide a very high signal-to-noise ratio. Each sensor/stimulator includes a power rectifier circuit, a line interface circuit, a state machine controller, at least one sensor that generates an analog output current as a function of a sensed parameter, a low power current-to-frequency converter circuit, and a counter circuit.
