Title: Rational frequency synthesizers
Inventor: PETROVIC BRANISLAV A
IPC: H03L7/08
Filed: 2001-05-24
Granted: 2011-10-04
Abstract: A single loop PLL frequency synthesizer, suitable for frequency applications in the MHz and GHz range, operates at high comparison frequencies (on the order of 100 MHz and higher), with excellent phase noise performance, but allows for small frequency steps (on the order of 10 kHz or less), and is suitable for integration within Application Specific Integrated circuits (ASICs). The basic principle of operation of the Rational Frequency Synthesizer is that the output frequency and the reference clock frequency always have a rational relationship (i.e. the ratio of the two frequencies can always be represented as a ratio of two integer numbers). This ratio can always be expanded into various expressions of equivalent fraction expansions.  The equivalent fractions take the form of a series of divided, added or subtracted terms, each term itself being a rational number. For each synthesized frequency, the computation of expansion terms yields specific, different values of the terms, with possibly multiple solutions. The realization in hardware of the computed fraction expansion terms is achieved by the means of a specific combination of frequency division and frequency translation (or freqeuncy conversion) of the reference clock frequency and/or of the oscillator frequency. The above is accomplished through multiple consecutive up or down conversions of these frequencies, using single sideband (SSB) mixers, where either the upper sideband (USB), or the lower sideband (LSB) can be selected by the frequency control means in combination with programmable frequency dividers or counters. The converted and/or divided frequencies are compared in a phase detector, followed by a loop filter in a closed loop manner that provides phase locking of the oscillator. The realization in hardware of the above functions is accomplished by using bi-level (digital) circuits in combination with analog circuits. All necessary frequency control algorithms, instructions, design parameters and values are stored in non-volatile memory, and are used by an on-board controller or micro-processor to generate frequency control signals for the synthesizer's hardware.

Title: Interrupteur inductif passif
Inventor: DINN DON
IPC: H02J7/00
Filed: 2003-02-04
Granted: 2008-06-03
Abstract: Interrupteur inductif passif pour relier une batterie à une charge dans un dispositif électronique à batterie déployé à distance. L'interrupteur fonctionne en réponse à un champ magnétique émis à une fréquence particulière. L'interrupteur inclut une antenne pour transformer le champ magnétique en une tension induite et un détecteur de tension pour capter la tension induite et déclencher un élément de commutation. L'interrupteur fonctionne en mode attente jusqu'à ce qu'une tension suffisante soit induite dans l'antenne, qui fait que l'interrupteur couple la batterie à la charge. En mode attente, l'interrupteur utilise une quantité négligeable de puissance, ce qui permet aux dispositifs d'être déployé sur le terrain pendant de longues périodes de temps sans consommer beaucoup de puissance de la batterie.

Title: Congestion control in an ip network
Inventor: IBEZIM JAMES A
IPC: H04L69/40
Filed: 2004-09-30
Granted: 2007-08-28
Abstract: Upon detection of an overload condition at a network element, the network element sends two messages to those other network elements which may potentially send request messages to the overloaded network element. If the network utilizes the SIP signaling protocol, then the messages sent by an overloaded network element are SIP INVITE and SIP CANCEL. The CANCEL message comprises an indication that the sending network element is unavailable and an amount of time which the recipient network elements are to wait before sending any requests to the overloaded network node. Upon receipt of these messages, the receiving network elements wait for a delay time period before sending any additional request messages to the overloaded network element. During the waiting period, the waiting network elements may send request messages to network elements other than the overloaded network element which provide functionality similar to that of the overloaded network element.

Abstract: D-glyceric acid has been found to enhance alcohol metabolism and thereby prevent adverse effects of alcohol consumption. D-glyceric acid is administered concurrently with alcohol, to accelerate the elimination of the alcohol from the body. D-glyceric acid is converted into D-glyceraldehyde an d further into glycerol in reactions catalysed by NADH-aldehyde dehydrogenase and NADH-alcohol dehydrogenase complexes, which are produced in excess durin g alcohol oxidation, in the cells of alcohol-metabolising tissues. In these reactions, the NADH complexes become NAD-aldehyde dehydrogenase and NAD- alcohol dehydrogenase complexes. These complexes which in turn accelerate th e oxidation of alcohol, which is paralleled by enhancement of acetaldehyde oxidation to metabolically harmless acetic acid. D-glyceric acid or its salt or ester is used for the manufacture of a pharmaceutical preparation for enhancing the metabolism of alcohol. A method of enhancing the metabolism of alcohol in a subject by administering said compounds an effective amount of D- glyceric acid or its salt or ester is disclosed.
