Title: Collapsible impeller for catheter pump
Inventor: ZENG ZIJING
IPC: A61M60/174
Filed: 2013-05-13
Abstract: An impeller 1200 for a catheter pump has a blade 1203 coupled to a hub 1201, the blade movable between a collapsed, stored position compressed against the hub 1201 and an extended position extending away from the hub 1201 and the blade 1203 having a shape or profile when in the extended position which is different when the impeller rotates than when the impeller is at rest due to deformation of the blade during operation causing elongation, or flattening, or an extended operation height of the blade 1203 or a change to a radius of curvature R of a curved surface of the blade. A sheath or external sleeve 1275 urged against a ramped or chamfered surface 1215 of the trailing edge of the blade 1203 may compress the blade 1203 in the collapsed, stored position. The pump may be a percutaneous rotary heart pump providing elevated flow rates with reduced risk of hemolysis and thrombosis.

Title: Solvent assisted inlet ionization (SAII) interfaces
Inventor: BROWN JEFFERY MARK
IPC: H01J49/04
Filed: 2012-11-02
Abstract: In SAII, an analyte dissolved in a solvent is introduced directly into a heated metal channel via a fused silica or metal solvent delivery tube so that ionization occurs without requiring a voltage or a laser. One end of the metal channel is held at a higher pressure than the other end and, generally, the channel may form the inlet of a mass spectrometer. A multi-inlet interface is disclosed in which an atmospheric pressure ionization source, such as an electrospray ion source 45, is provided in combination with an SAII interface. Also disclosed is a dual channel Solvent Assisted Inlet Ionisation (SAII) interface (see Figure 3) comprising a tube (8) having two or more separate channels. The tube is surrounded by heating element (2). Capillaries (4a & 4b) are preferably independently positioned within the separate channels. Alternatively, two physically separate channels (8a & 8b, Figure 5) may be provided, said channels being independently heated by separate heaters (2a & 2b). In an alternative embodiment, the two separate capillaries 4a & 4b may be positioned within a single heated channel (1, Figure 2).

Title: Waterblind
Inventor: FORD CHRISTOPHER JOHN
IPC: E06B9/00
Filed: 2014-02-12
Abstract: A flexible flood barrier comprising a flexible waterproof barrier 3 that is detachably attached to mounting channels 1. A mounting channel 1 is fixed horizontally at or below ground level at the property boundary, and identical mountings channels 1 are fixed vertically to the property to the required height. The mounting channels are U shaped and receive a bead 2 that is bonded to the lower end and vertical edges of the barrier 3. The barrier 3 has a degree of elasticity which allows the barrier to absorb shock and mould to contours when required, and the upper horizontal edge of the barrier 3 is held by fixings 5. When not in use, the barrier 3 can be lowered and removed for storage, while the mounting channels can remain in situ for future use. Alternatively the barrier 3 can be lowered and rolled for storage at or below ground level. The barrier may be used as a temporary flood defence against a river or other watercourse breaking its banks (fig 6, 7 & 8), where the mounting channel is embedded into a plinth (10 fig 6) on the riverbank, and mounted to temporary vertical support posts (11, fig 8).
Patent GB-2510268-A (GB)
Title: Declination compensation for seisimic surveys
Inventor: ROBERTS PHILLIP
IPC: G01V1/38
Filed: 2012-05-07
Abstract: In seismic survey for icy waters, streamers are towed behind a vessel under the water's surface to avoid ice. GPS readings may not be consistently obtained because the ice prevents a tail buoy with a GPS receiver from trailing from streamer at the surface. Instead, a device tows on the streamer under the water's surface. The streamer's absolute position is tracked by intermittently bringing the towed device toward the surface so GPS readings can be obtained. The streamer's absolute position can then be used in conjunction with compass readings and can correlate various seismic sensor signals obtained along the streamer during the survey. The compass readings can be corrected for declination using declinometer readings, which can be compensated for iron effects from the vessel or other device carrying the declinometer.

Patent GB-2533292-A (GB)
Title: Differential data access
Inventor: CHRISTOPH MARTIN ANGERER
IPC: G06F9/30
Filed: 2014-12-15
Abstract: By storing a data element as a base word in a first precision, and one or more delta words comprising additional information related to a second precision version of the stored data element, data may be read to different precision. This allows faster processing, requiring lower bandwidth for certain estimate calculations, whilst allowing the more accurate data to be read from different memory banks. The delta words may be added as least significant bits to the base word, or the first part added as most significant bits, and a second part as least significant bits. The base word may have a defined bit width typically the register width of the CPU. This therefore differs from the long double, double-double or quadruple precision floating point formats.

Title: Integrated capacitor based power distribution
Inventor: MANIPATRUNI SASIKANTH
IPC: G11C11/16
Filed: 2013-03-15
Abstract: An embodiment provides power (having low voltage, high current, and high current density) to ultra low voltage non-CMOS based devices using a distributed capacitor that is integrated onto the same chip as the non-CMOS devices. For example, an embodiment provides a spin logic gate adjacent dielectric material and first and second plates of a capacitor. The capacitor discharges low voltage/high current to the spin logic gate using a step down switched mode power supply that charges numerous capacitors during one clock cycle (using a switching element configured in a first orientation) and discharges power from the capacitors during the opposite clock cycle (using the switching element configured in a second orientation). The capacitors discharge the current out of plane and to the spin logic devices without having to traverse long power dissipating interconnect paths. Other embodiments are described herein.
