Title: Child seat cover
Inventor: RUNK KELLY L
IPC: B60N3/00
Filed: 2004-03-23
Abstract: A cover for a child seat in the form of a pad with slots through the pad that facilitate simple removal and reinstallation of the cover. Some of the slats accommodate the seat safety harness and merge with side slots that are held closed by mating separable fastening elements. The side slots extend at least partially along the junction between the backrest portion and the side bolster portions of the pad. A pair of back slots extend from respective strap anchoring locations in the backrest region to respective side slots. A release slot may be included at each side of the pad, extending from the respective side slot to the adjacent outer side edge of the pad - this being especially useful with three-point harness seats. A five-point harness version has a pair of lap strap slots through the pad to accommodate the lap straps of the harness. The lap straps slots extend outwardly to the adjacent side slots.  Adding release slots as described gives this latter cover universal application.

Title: Method for varying the power consumption of capacitive loads
Inventor: KREITTMAYR JOSEF
IPC: H03K17/725
Filed: 2004-04-01
Abstract: The invention relates to a method for varying the power consumption of capacitive loads, in particular compact fluorescent lamps which are operated using a phase-gating dimmer by means of a converter (step-up converter). According to the invention, in the case of a nonconducting dimmer (i.e. no system power supply to the load), the switch (T1) in the converter (step-up converter) is closed. In the case of a conducting dimmer (i.e, when a system voltage is applied to the load), the step-up converter operation takes place until a predetermined maximum voltage is reached across the smoothing capacitor of the load.

Abstract: Moteur de générateur d'impulsions amélioré, intelligent et écoénergétique utilisé pour générer des impulsions de boue dans une application de MWD (mesure en cours de forage). Dans le générateur d'impulsions, un circuit de commande alimenté par un courant continu (CC) fait fonctionner un moteur électrique rotatif réversible comme un moteur à CC triphasé sans balai qui commande une servo-vanne. L'ouverture de la servo-vanne stabilise la pression dans un plenum, ce qui permet le fonctionnement d'une vanne principale réduisant la zone d'écoulement et cause une pointe de pression dans la colonne de boue. La fermeture de la servo-vanne crée une réduction de pression de la boue qui fait fonctionner la vanne principale et agrandit la zone d'écoulement, ce qui met fin à la pointe de pression. La servo-vanne est alimentée au moment de l'ouverture et de la fermeture par le moteur électrique rotatif réversible. Le moteur électrique rotatif réversible comporte des capteurs intégrés et peut, par exemple, détecter des blocages et/ou déclencher, notamment, des mesures visant à débloquer l'écoulement de boue.

Abstract: A long term oxygen therapy system having an oxygen supply directly linked with a patient's lung or lungs may be utilized to more efficiently treat hypoxia caused by chronic obstructive pulmonary disease such as emphysema and chronic bronchitis. The system includes an oxygen source, one or more valves and fluid carrying conduits. The fluid carrying conduits link the oxygen source to diseased sites within the patient's lungs. A collateral ventilation bypass trap system directly linked with a patient's lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs, thereby treating another aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve and an air carrying conduit. In various embodiments, the system may be intrathoracic, extrathoracic or a combination thereof. A pulmonary decompression device may also be utilized to remove trapped air in the lung or lungs, thereby reducing the volume of diseased lung tissue. A lung reduction device may passively decompress the lung or lungs. In order for the system to be effective, an airtight seal between the parietal and visceral pleurae is required. Chemical pleurodesis is utilized for creating the seal and various devices and/or drugs, agents and/or compounds may be utilized to accelerate wound healing in thoracic anastomosis applications.             ~~~~~~

Title: System and method for partially encrypted multimedia stream
Inventor: PEDLOW LEO M JR
IPC: H04N7/167
Filed: 2004-03-08
Abstract: A multimedia stream head end includes a legacy conditional access (CA) device (20) that fully encrypts the stream using legacy keys. A copy of the stream is sent to a secondary CA device (24) that encrypts only critical packets in the stream using secondary keys to render a partially encrypted stream. The critical packets in the fully encrypted stream from the legacy CA device (20) are obtained and inserted next to the corresponding critical packets in the partially encrypted stream. Thus, only critical packets are encrypted, with encrypted versions being generated by both the legacy CA (20) and secondary CA  (24) without the legacy CA (20) knowing which of the packets that it encrypts are "critical".
