Abstract: L'invention concerne un appareil de radiochirurgie alimenté par un circuit électronique fonctionnant avec un courant haute fréquence, ce circuit comprenant : un circuit de redressement (20) alimenté par la tension aux bornes qui fournit une tension pulsatoire de redressement (201) à un circuit haute fréquence (30) ; un circuit haute fréquence (30) capable d'émettre un signal (301) de courant de sortie avec une fréquence constante dans l'échelle des MHz, ce signal alimentant l'appareil de radiochirurgie au moyen d'un transformateur (40) haute fréquence. On obtient ce circuit haute fréquence (30) en pilotant un MOS (métal-oxyde-semiconducteur) (305) dans un circuit de pilotage (306) comprenant un oscillateur à quartz dont la fréquence d'oscillation représente au moins deux fois la fréquence de fonctionnement habituelle du MOS. Le circuit de pilotage (306) est commandé par un circuit de commande (310) de courant microprocesseur disposé derrière le MOS (305) et il est tel qu'il peut maintenir le courant du circuit haute fréquence à une valeur compatible avec l'énergie pouvant être dissipée par le MOS indépendamment de toute variation de l'impédance de charge du circuit.

Title: Collector of unused water
Inventor: NAOUM DIMITRIOS
IPC: E03C1/122
Filed: 1999-07-05
Granted: 2009-03-10
Abstract: It is a device which is placed underneath all kinds of taps and collects the pure unused water which escapes during the intermediate intervals of a use. The device consists of two spherical sections (12 and 13 ) firmly connected to each other, having internally various constructions and components (1, 2, 4, 6, 7, 8, 9, 14), with the purpose of collecting the clean water and of preventing the entry of the used water into the head of the collector. The rest of it consists of a very flexible pipe (3) which drives the water outside the place of use and of the drain (10, 5, 11) which leads it to the storage area. The collection of the water is achieved by taking advantage of the concentrated energy of the column of the water at one point (when we turn on the tap) whe n we do not use it. The opposite prevents the entry of the used water. The invention is to be used both for household uses (kitchen, bathroom) and places of personal hygiene for the personnel of small and big factories, etc.

Abstract: An external pipe leak repair technique is provided for arresting a leak occurring on an operating pipe in conjunction with an external pipe reinforcing sleeve arrangement. An installation apparatus is first placed over the leak to remove and divert the flow of errant fluids from the leak to create a safe working environment. Then a leak- arresting plug is placed over the leak and an elastomeric portion of the plug is pressed into the leak. After cleaning in the vicinity of the leak, the leak-arresting plug is affixed to the pipe using a binding agent. Then the outer surface of the pipe and the inner surface of the pipe reinforcing sleeve are cleaned, and an epoxy filler material is applied to the pipe over the area to be covered by the external pipe reinforcing sleeve and over the leak--arresting plug. A depression is ground into a part of the sleeve to accommodate the protruding leak-arresting plug and binding agent above the pipe's outer surface. The sleeve is then installed around the pipe to mechanically support the leak- arresting plug. The leak-arresting plug, binding agent, and epoxy act both as a filler agent and sealant, arresting the leak and filling all voids between the pipe and the sleeve. The leak-arresting plug prevents the pipe from leaking, the sleeve prevents the anomaly from rupturing, and the binding agent / epoxy acts as a secondary mechanism to prevent product leakage. The pipe sleeve therefore act as one unit, expanding and contracting with fluctuations in the pipe's pressure and temperature.

Title: Digital hearing aid system
Inventor: ARMSTRONG STEPHEN WADE
IPC: H04R25/00
Filed: 2002-04-11
Granted: 2007-07-03
Abstract: A digital hearing aid is provided that includes front and rear microphones, a sound processor, and a speaker. Embodiments of the digital hearing aid include an occlusion subsystem, and a directional processor and headroom expander. The front microphone receives a front microphone acoustical signal and generates a front microphone analog signal. The rear microphone receives a rear microphone acoustical signal and generates a rear microphone analog signal. The front and rear microphone analog signals are converted into the digital domain, and at least the front microphone signal is coupled to the sound processor. The sound processor selectively modifies the signal characteristics and generates a processed signal. The processed signal is coupled to the speaker which converts the signal to an acoustical hearing aid output signal that is directed into the ear canal of the digital hearing aid user. The occlusion sub-system compensates for amplification of the digital hearing aid user's own voice within the ear canal. The directional processor and headroom expander optimizes the gain applied to the acoustical signals received by the digital hearing aid and combine the amplified signals into a directionally-sensitive response.

Abstract: A braking system control requires that a first or service braking system be actuated before a second or parking braking system can be released to prevent unexpected movements. A sensor senses that the service brakes are engaged and controls a device to release the parking brakes. A latch ensures that the parking brakes remain released. For example, a piston and check valve form the sensor and latch. Service brake pressure works against the piston. Above a threshold level, service brake pressure drives the piston to open a valve that provides pressurized air to a parking brake release system. Once released, the check valve directs parking brake release pressure to the piston to keep the valve open.

Granted: 2012-01-10
Abstract: An electronic locking system (10) comprises a cylinder (14) housed within and rotatable with respect to a shell (16). A key (18) has a power supply (28). At least one of the key (18) and the cylinder (14) is capable of generating a signal when the key (18) is electrically connected with the cylinder (14). An electrically powered locking mechanism is housed within the cylinder (14) and includes a lock member (12) moveable between an open position and a locked position. The lock member (12) in the locked position interferes with movement of the cylinder (14). A power source (28) is connected to the locking mechanism in response to the signal. The locking mechanism allows movement of the lock member (12) from the locked position to the open position in response to the signal so that the cylinder (14) may be rotated within the shell (16). The cylinder (14) further includes an interfering member that resists movement of the locking member (12). In addition, a biasing mechanism urges the cylinder (14) toward a home position when the cylinder (14) is rotated away from the home position.

Granted: 2009-09-08
Abstract: A unified architecture for a multipoint VC session and interactive broadcasting system is provided that includes a server, one or more video accessing points, reflectors and client machines. The server sets up the vid eo communication sessions (VC sessions), each of which is hosted by one video accessing point. The server downloads the A/V client software to client machines. Reflectors direct audio/visual signals to client machines. The reflectors are coupled to the video accessing point and receive a control signal from the video accessing point in order to direct the A/V signals fro m the client machines participating in the VC session. The client machines process all of the A/V signals. This system for distributing the VC session tasks across these components reduces any bottleneck effect from using a single, central control point to direct the VC session and route the A/V signals. The server, also, serves as a ticket agent, and is configured to issue and redeem tickets for specific VC sessions and broadcasts through the use of a session booking module. Finally, the downloading process of the A/V client software prevents software incompatibility among participants and enables low storage devices such as handheld devices to participate.
