The present invention discloses handheld photocosmetic devices that can be utilized to apply EMR to the skin, e.g., to achieve fractional treatment of the skin. The invention discloses effective fractional photocosmetic devices for use in by a consumer in a non-medical and or non-professional setting. Thus, embodiments of such devices are disclosed herein that have one or more of the following attributes: capable of performing one or more cosmetic and/or dermatological treatments; efficacious for such treatments; durable; relatively inexpensive; relatively simple in design; smaller than existing professional devices (with some embodiments being completely self-contained and hand-held); safe for use by non-professionals; and/or not painful to use (or only mildly painful).

A three-dimensional (3D) high density memory array includes multiple layers of segmented bit lines (i.e., sense lines) with segment switch devices within the memory array that connect the segments to global bit lines. The segment switch devices reside on one or more layers of the integrated circuit, preferably residing on each bit line layer. The global bit lines reside preferably on one layer below the memory array, but may reside on more than one layer. The bit line segments preferably share vertical connections to an associated global bit line. In certain EEPROM embodiments, the array includes multiple layers of segmented bit lines with segment connection switches on multiple layers and shared vertical connections to a global bit line layer. Such memory arrays may be realized with much less write-disturb effects for half selected memory cells, and may be realized with a much smaller block of cells to be erased.

An improved E-field generator including a slow-wave transmission line structure is provided herein. In some cases, the improved E-field generator may include an inductively-loaded slow-wave transmission line structure driven by a power source at one end of the structure and terminated by a load at the other end of the structure. In other cases, the improved E-field generator may include a capacitively-loaded slow-wave transmission line structure. In either case, the improved E-field generator provides a frequency-independent, significantly increased electric field at a distance spaced from the generator without altering the dimensions of the generator and/or the input power supplied to the generator. The increase in generated field intensity is achieved by decreasing the phase velocity of the electromagnetic wave propagating along the parallel elements of the generator.

A light control and display technology applicable to light redirection and projection with the capacity, in a number of embodiments modified for particular applications, to produce managed light, including advanced images.

An intragastric balloon and method of adding and/or removing fluid therefrom are disclosed. The intragastric balloon includes a shell, a grasping tab, and a self-sealing portion. A gastroscopic instrument which includes a grasping tool is inserted into the stomach of a patient and used to grasp the grasping tab located on the surface of the shell. Using the grasping tool, the intragastric balloon is securely fastened to the gastroscopic instrument. A filling instrument, such as a needle, is advanced through the self-sealing portion of the shell for the filling or deflating of the intragastric balloon. After inflation or deflation is complete, the filling instrument is then withdrawn from the balloon and the gastroscopic instrument withdrawn from the stomach.

An advanced antenna or set of antennae for a wireless device is provided by embedding the antennae into the battery case or generally the largest surface area of a wireless phone. The antenna connections are made through the battery's connections to the wireless device. The antenna design can be compact and located in any area of the battery. The antenna design can be thin and flat, located at the back surface of the battery or the large rear surface of a wireless phone, facing away from the user. An RF shielding device can be embedded into the battery and configured in relation to the antenna such that the RF field intensity and the consequent specific absorption rate for the user is lowered while the outgoing signals of the wireless device remain fully adequate for the function of the wireless device. This feature is preserved for a multi-band operation because a digital phase shifter is used between two radiating antennae. An external case is used as a complement to the wireless phone to provide additional antennae, power and capability.

A holder for a flexible leaflet prosthetic aortic heart valve that is less bulky than earlier holders and minimizes obstructions to vision and working space around the valve to facilitate implantation thereof. The holder may have a central hub and three outwardly extending legs that connect directly and exclusively to tips of the commissures of the aortic heart valve for better tactile feedback when parachuting and seating the valve in the annulus. The legs are sized so that they do not overlap the commissure tips and therefore afford a better view of the sewing ring adjacent the commissures. The legs may be narrow in the midsection or split into two rails to increase visibility of the valve leaflets. The hub may be vaulted axially upward relative to the outer ends of the legs to further increase visibility of the valve. A more secure engagement between the central hub and a delivery handle is also provided to ensure the holder/handle connection does not become loose during suture placement through the sewing ring and fewer handle revolutions are required to screw in and unscrew the handle from the holder.

A distractor for separating adjacent elements, such as vertebrae. The distractor preferably has a scissors-type distracting mechanism, either in a simple scissors or double-acting scissors configuration. A set of blades is provided on each jaw such that an implant may be inserted between the spaced apart blades. The set of blades includes at least two blades.

In an exhaust gas pipe, a first fluid flows in a flow direction in the pipe, and a second fluid is injected inside the pipe by a nozzle, from an injection inlet arranged in the pipe wall, according to an injection direction. A mixing device fastened inside the pipe upstream from the injection inlet creates turbulence that helps the mixing of the fluids. The mixing device has a first portion located on the injection inlet side of the pipe and a second portion located opposite the injection inlet side of the pipe, the portions being designed so that the fluid velocity is higher downstream from the mixing device second portion than downstream from the mixing device first portion. An aqueous solution of urea can be injected inside an exhaust pipe of a diesel engine.

A method of simultaneously transmitting and receiving multiple data packets over wireless channels among the nodes of a wireless network is provided. The method includes automatically selecting a master sending node and corresponding master receiving node in response to an omni-directionally transmitted request to send during a contention period. The method also includes selecting a slave sending node and corresponding slave receiving node if a spatial reuse ratio correspond to the master-node pair is less than a predetermined threshold and if directional data transmissions between the slave sending node and corresponding slave receiving node avoid interfering with directional data transmissions between the master nodes and other pairs of slave nodes. The method further includes causing the master sending node and slave sending node to directionally transmit data packets during a coordination period.

A housing (1) for a fluid flow engine comprises a first rotor space (2) for receiving and housing a turbine rotor, a bearing space (4) to house a shaft (5) of said turbine rotor, and a second rotor space (3) for receiving and housing a compressor rotor. The housing portions, which surround the bearing space (4), are integrally formed at least in part with those portions that surround at least one of the rotor spaces (2,3).
