Abstract: An exercise apparatus is implemented with a frame with a horizontal and vertical component and a rotatable endless belt mounted on the horizontal frame component, the belt having a surface for supporting a user. Vertical frame component has an upper body engaging element connected thereto and adapted to engage the shoulders of a user during a portion of an exercise cycle. An actuator is disposed between the upper body engaging element and the vertical frame component, wherein an increase in actuator length raises the height of the upper body engaging element relative to the belt. The upper body engaging element is positioned at a start position of low height to engage the user in a low-level position at a beginning of the exercise cycle, and the upper body engaging element increases in height as the user accelerates and rises to a fully upright position.

Abstract: The gas turbine engine shroud comprises a plurality of circumferentially-disposed and concentric shroud segments. Each shroud segment has an arc-shaped platform with opposite ends, each end comprising an inter-segment seal slot, at least one slot extending substantially across each corresponding end and having a lengthwise-variable depth.

Abstract: A diffuser for a centrifugal impeller assembly of a gas turbine engine includes a diffuser case having a plurality of vanes extending therein defining a plurality of circumferentially distributed angled passages in communication with an inlet space. Each vane includes a bleed port defined in a suction surface thereof, in proximity of the leading edge. The diffuser case includes a passive fluid communication defined at least partially through each one of the vanes between each bleed port and the inlet space upstream of the leading edge, such that air bled through the bleed ports is recirculated upstream of the leading edges to the inlet space to increase a surge margin of the diffuser.

Abstract: A fluid jet for injecting fluids in the liquid of a tub through a throughbore in a wall of the tub comprises a gas injector with a hollow body having a gas inlet receiving a gas flow from a pressurized gas source. A gas outlet produces a flux of gas with the gas flow. A liquid injector comprises a hollow body with a liquid inlet connected to a pressurized liquid source to receive a liquid flow therefrom. A liquid outlet produces a flux of liquid with the liquid flow, the gas injector being received in the hollow body of the liquid injector, for the gas outlet and the liquid outlet to form a common jet outlet. The liquid injector is secured to the wall of the tub opposite the throughbore such that fluids exiting the common jet outlet are directed concurrently through the throughbore into the liquid of the tub.

Abstract: A system for (and a method of) selectively establishing communication with one of plural devices associated with a single telephone number is provided. In a preferred embodiment, the system includes a wireless connect unit connected between an enterprise private branch exchange (PBX) network and a public switched telephone network. The wireless connect unit preferably serves as a gateway between the PBX and one or more remote communication devices. The remote devices can be used as standard PBX office telephones for both inbound and outbound telephone calls. Thus, features of the PBX network (e.g., voice mail, direct extension dialing, corporate calling plan, etc.) are available to the remote device even though they are not physically connected to the PBX. When the system receives an incoming call, it can route the call to an office telephone and one or more of the remote devices simultaneously or as desired by the user.

Abstract: A hybrid gas compressor has at least one rotor and shroud which define a compressor gas path extending from an inlet to an outlet. The compressor includes at least two compression stages and one diffusion stage between the inlet and outlet, the compression stages including respective circumferential arrays of blades extending from the rotor and the diffusion stage including a circumferential array of vanes between the compression stages. Blade aerodynamic loadings may be controlled, particularly in the last stage, to provide desired compression characteristics across the compressor. A bleed outlet is optionally located between the inlet and outlet for bleeding from the gas path.

Abstract: Electric machines comprising a plurality of magnetized rotors, preferably including bi-pole magnets. The rotors are configured to drive and/or be driven by a common shaft, as for example by suitable configurations of gears. The rotors are magnetically indexed, in pairs, with respect to each other and to corresponding electrical windings, such that, when a current is passed through the one or more windings, the rotors provide phased rotary power to the common shaft; or, when torque is applied to the common shaft, a phased electrical output is provided to the windings.

Abstract: A fluid conduit coupling for a turbofan engine wherein the engine has a gas path defined by inner and outer duct walls and the exterior surface of the outer duct wall is readily accessible for visual inspection. In one example, a first fluid line extends across the gas path between the inner and outer duct walls and a second fluid line is connected to the first fluid line at the level of the outer duct wall. The first fluid line may include a female coupling member and the second fluid member may include a mating male coupling member. An annular sealing member is associated with the first and second couplings and a leak path is defined between the annular sealing member and the exterior surface of the outer duct wall, whereby fluid may be detected by visual inspection of the outer duct wall if a leak should occur at the annular sealing member.

Abstract: A system for filling medication dose packs with oral-solid medication items comprises storage tray drawers each having storage trays. Each storage tray stores a specific type of oral-solid medication item. The storage tray drawers are displaceable to a drawn position to expose the storage trays thereof. A table supports dose packs having a plurality of receptacles arranged in rows, with each receptacle associated with an intake time and date of a patient prescription file. A dispensing mechanism has fingers for grasping by suction an oral-solid medication item, and degrees of freedom to displace the fingers from any one of the storage trays to the dose pack, to transfer the oral-solid medication items from the storage trays in the drawn position to the receptacles of the dose pack.

Abstract: Bipolar membrane electrodialysis (BMED) was used to separate lipids from biological solutions. The lipids are separated from animal as well as vegetable solutions. Particularly, bipolar membrane precipitates high levels of lipids from a biological solution. The BMED single step process improves significantly lipid precipitation rates in several biological solutions of different natures.
