Abstract: Pour effectuer une synchronisation approximative de fréquences, compensant un écart de fréquences porteuses par rapport à une fréquence d'oscillateur dans un système de démodulation (130), un premier signal est d'abord reçu. Ce système de démodulation (130) permet de démoduler un signal présentant une structure de trame qui comprend au moins un symbole utile (162) et un symbole de référence (166) et constitue une séquence modulée en amplitude. Ensuite, la fréquence du signal reçu est abaissée. Une démodulation en amplitude du signal dont la fréquence a été abaissée est effectuer pour générer une enveloppe. Cette dernière est corrélée à un schéma de référence prédéterminé pour déterminer l'écart de fréquences des porteuses. Enfin, la fréquence de l'oscillateur est contrôlée en fonction de l'écart de fréquence des porteuses. Le symbole de référence peut comprendre deux séquences identiques (300). Dans ce cas, l'enveloppe obtenue par la démodulation d'amplitude comporte deux parties qui sont fondées sur les séquences identiques (300). Une des parties de l'enveloppe est corrélée à l'autre des parties pour déterminer l'écart de fréquences porteuses. La fréquence de l'oscillateur est contrôlée en fonction de l'écart de fréquence des porteuses déterminé.

The plunger includes a hollow sleeve that is disposed over and extend beyond an inner rod. The plunger includes a hollow cutter extending from the inner rod and a stopper disposed over the end of the sleeve. The plunger has a displaceable collar to prevent movement of the inner rod with respect to the sleeve, that is by distal force to the plunger by engagement with the proximal end of the barrel allowing the cutting surface to cut through the stopper. There is a hub with a stem, a proximal flange and an engagement. A clip having a proximal foot with an opening therethrough and a distal grip is disposed on the stem of the hub. The proximal foot of the clip is disposed at the distal surface of the flange and the grip at the engagement on the stem. There is a spring disposed about the stem compressed between the receiver and the clip to provide a bias, so that when sufficient force is applied to the plunger causing; the cutting surface to cut through the stopper, the cutting surface then engages, cuts through the flange to engage the clip and cause the clip to release the engagement on the stem. This allows the spring to urge the hub to a position within the syringe.

Title: Hybrid thermionic energy converter and method
Inventor: KUCHEROV YAN
IPC: H01L35/30
Filed: 2000-03-06
Granted: 2011-07-12
Abstract: The present invention embodies a solid state thermionic energy converter and is directed to a method and apparatus (10, 104, 108) for conversion of thermal energy to electrical energy, and electrical energy to refrigeration. The present invention maintains a thermal separation between an emitter (12) and a collector (16) through a fractional surface contact (13, 42, 44) of decreasing cross-sectional area towards the point of contact. The fractional surface contacts (13, 42, 44) may be associated with the emitter (12), a barrier (14), or the collector (16). Maintaining a thermal separation between the emitter (12) and the collector (16) provides for ballistic electron transport through the barrier (14) and reduces the transport of electrons through thermal conductivity. Hence, the efficiency is increased through the collection of ballistic electrons and the reduction of thermal conductivity electrons which cannot be collected. The inventive principle works for hole conductivity, as well as for electrons.
