Title: Trip indicator for circuit breaker
Inventor: ULERICH PHILLIP LLOYD
IPC: H01H71/46
Filed: 2002-01-10
Abstract: An indicator apparatus for a circuit breaker includes an indication mechanism and a latch mechanism mounted on a base, the base being mounted within the circuit breaker. The indication mechanism includes an indicator movably mounted on the base and being translatable along a longitudinal axis between a retracted position and an extended position, with the indicator in the extended position providing an indication visible from the exterior of the circuit breaker of a tripped condition of the circuit breaker. The latch mechanism includes a latch that is pivotable between a blocking position and a release position, with the latch in the blocking position being engageable with a ledge on the indicator to retain the indicator in the retracted position. The indicator is biased to the extended position by a first biasing device, and the latch is biased to the blocking position by a second biasing device.  The abstract shall not be used for interpreting the scope of the claims.

Title: Implantable ventricular assist device
Inventor: JASSAWALLA JAL S
IPC: A61M60/896
Filed: 1999-12-15
Abstract: An implantable ventricular assist device (VAD) has a small size to provide full-implantable capabilities. The VAD has two variable-volume chambers and an actuator for expelling blood from the chambers in sequence and to a common outlet, thus operating as a positive-displacement pump.  The variable-volume chambers may be flexible sacs and the pump is operable at a substantially continuous flow, such as during the systolic phase of the assisted ventricle. A method of operation includes operating the pump at a first frequency during systole and a second lower frequency during diastole.  The VAD pump may include a pair of coils housed within a frame and disposed in a spaced relationship to generate a coil flux through a pair of poles. A plate including an armature and a magnet is disposed within the frame such that the armature is between the poles and the magnet is between the coils. Gaps are defined between the armature and each of the poles and the coil flux displaces the armature across the gap. The volume of the chambers is a fraction of the ventricular volume, and may be about 20 ml.

Abstract: L'invention concerne une composition et un procédé permettant de préparer des résines imide haute performance pouvant être traitées par des procédés de moulage par transfert de résine (procédé RTM) et par injection de résine (RI). Des matériaux présentant une combinaison de propriétés les rendant particulièrement adaptés à la fabrication d'éléments composites par des techniques RTM ou RI ont été préparés et caractérisés, puis transformés en éléments moulés et en composites renforcés de fibres de carbone dont on a déterminé les propriétés mécaniques. Ces matériaux conviennent particulièrement à la fabrication de composants structurels composites dans les applications aérospatiales. Le procédé permettant de préparer les résines haute performance pour procédés RTM et RI comprend plusieurs processus distincts. Il consiste à préparer un mélange de produits à partir d'une combinaison de diamines aromatiques et de dianhydrides aromatiques avec des poids moléculaires théoriques relativement bas (ou un écart stoechiométrique important) et à réaliser un coiffage terminal avec des groupes réactifs latents. La combinaison de ces monomères donne un mélange de produits de forme imide, qui présente une viscosité stable à la fusion, inférieure à environ 60 poise en dessous d'environ 300 ·C.

Title: Adjustable-height ladder
Inventor: SHANNON KYLE
IPC: E06C1/39
Filed: 2002-02-26
Abstract: An adjustable-height stepladder has an upper-front frame and an upper-rear frame interconnected by a top member. The upper-front frame and the upper-rear frame each have an elongate slide track. A lower-front frame, wider than the upper-front frame and positioned centrally rearward thereof, has a pair of rails, each having a slide mechanism slidingly engageable with the slide track of the corresponding upper-front frame rail. A lower-rear frame, wider than the upper-rear frame and positioned centrally forward thereof, has a pair of rails, each having a slide mechanism slidingly engageable with the slide track of the corresponding upper-rear frame rail. Each slide mechanism has a hinged swing arm and a biasing spring, the combination of which allows the slide mechanisms to engage the slide tracks although the lateral distance between the upper-frame rails and their corresponding lower-frame rails may vary.  Accordingly, the stepladder is height-adjustable when the rails of the various frames are flared as well as when they are parallel.

Title: Ram having dynamically switchable access modes
Inventor: WIATROWSKI JACEK
IPC: G11C11/4193
Filed: 2002-03-28
Abstract: A row addressing circuit for DRAM memory is disclosed. Additional address or mode bits are used to dynamically select between long page and short page access modes, and to dynamically select between single cell per bit and dual, or two cell per bit modes in each memory bank within a memory block. In the short page access mode, only one wordline in a memory block is activated. In the long page access mode, two wordlines in the memory block are activated for accessing twice the number of bits as in short page access mode. In the single cell per bit mode, one bit of data is stored in one DRAM cell. In the two cell per bit mode, the row addressing circuit simultaneously activates two wordlines in a bank of the memory block to access one DRAM cell connected to each bitline of a pair of complementary bitlines for writing and reading complementary data. The row addressing circuit can combine the different access modes for system design flexibility.

Autocorrelation points at various bit delays independently or in combination with average optical power may be used to detect and/or quantify one or more of the following: loss of data modulation, signal contrast, pulse broadening, peak power fluctuations, timing jitter, and deviations from the pseudo-random character of data. In addition, the OPM may be configured to perform Fourier transformation based on the autocorrelation points to obtain corresponding spectral components. The spectral components may be used to detect and/or quantify one or more of chromatic dispersion, polarization mode dispersion, and misalignment of a pulse carver and data modulator. The OPM may be further configured to generate feedback, e.g., to network operators to improve network performance.
