A Single Electron MOS Memory (SEMM), in which one bit of information is represented by storing only one electron, has been demonstrated at room temperature. The SEMM is a floating gate Metal-Oxide-Semiconductor (MOS) transistor in silicon with a channel width (about 10 nanometers) which is smaller than the Debye screening length of a single electron stored on the floating gate, and a nanoscale polysilicon dot (about 7 nanometers by 7 nanometers by 2 nanometers) as the floating gate which is positioned between the channel and the control gate. An electron stored on the floating gate can screen the entire channel from the potential on the control gate, and lead to: (i) a discrete shift in the threshold voltage; (ii) a staircase relation between the charging voltage and the shift; and (iii) a self-limiting charging process. The structure and fabrication of the SEMM is well adapted to the manufacture of ultra large-scale integrated circuits.

A rechargeable battery assembly comprises a rechargeable battery unit and a data and power connector plug. The battery assembly has a deployed configuration in which the battery assembly has the general form of and functions as a conventional battery format, and a recharge configuration in which the data and power connector plug is made accessible to enable said connector to be connected to a suitable receptacle on a computing or peripheral device for recharging of the battery.

A multi-layer armature for a moving armature receiver. The armature includes a first armature layer and a displacement region. The first armature layer includes a first surface and a second armature layer having a second surface positioned adjacent to the first surface. The displacement region provides relative displacement between the armature layers. The multi-layer construction of the armature in combination with the displacement region creates considerable design freedom in choosing armature geometry outside conventional bounds posed by the above-mentioned constraint between armature cross-sectional area and its mechanical stiffness. The design freedom can be applied to achieve numerous performance benefits for the moving armature receiver such as higher electroacoustic conversion efficiency, increased maximum sound pressure output or smaller overall length of the multi-layer armature. The smaller length leads to a smaller size of moving armature receivers which is an important performance metric for moving armature receivers for numerous severely size-constrained applications.

A system and method for high-speed, low-power cryogenic computing are presented, comprising ultrafast energy-efficient RSFQ superconducting computing circuits, and hybrid magnetic/superconducting memory arrays and interface circuits, operating together in the same cryogenic environment. An arithmetic logic unit and register file with an ultrafast asynchronous wave-pipelined datapath is also provided. The superconducting circuits may comprise inductive elements fabricated using both a high-inductance layer and a low-inductance layer. The memory cells may comprise superconducting tunnel junctions that incorporate magnetic layers. Alternatively, the memory cells may comprise superconducting spin transfer magnetic devices (such as orthogonal spin transfer and spin-Hall effect devices). Together, these technologies may enable the production of an advanced superconducting computer that operates at clock speeds up to 100 GHz.

The present invention relates to an improved cerebrospinal fluid shunt system comprising a coating covering at least part of the system and a flow restricting component exerting a passive and essentially constant resistance to flow. The present invention also relates to methods for implanting different catheters of a cerebrospinal fluid shunt system into a brain ventricle and the sinus system, respectively, of an individual. The present invention further relates to methods for shunting cerebrospinal fluid from a brain ventricle to the sinus system of an individual.

A spread illuminating apparatus includes: a light conductor plate; at least one LED disposed at a side surface of the light conductor plate; an FPC including a substrate and first and second conductive patterns formed respectively at the front ad rear surfaces of the substrate; and a heat radiating plate to hold the FPC. The LED is mounted on electrode pads formed at the first conductive pattern of the FPC, and all the side faces of the LED are covered with an individual thermal conductor enclosure which is connected to the second conductive pattern via an opening formed at the substrate of the FPC. Thus, a heat radiation system is established from the side faces of the LED through to the heat radiating plate which is affixed to the rear surface of the FPC.

A method and apparatus for performing minimally invasive hip surgery for implanting a prosthetic acetabular component into a natural acetabulum. The method and apparatus include a posterior retractor having handle and retracting sections. The retracting section retracts soft tissue in the posterior section of the surgical site and includes a paddle with a curved flare and an elongated curved prong extending outwardly.

A razor has an elongate handle body with a shaving head at one end, the other end of the handle body as a body cavity for receiving a trimming wand with a smaller blade than the shaving head. The trimming wand is normally concealed by the razor body but can be selectively exposed for use by sliding the trimming wand, along the razor body, pivoting the trimming wand, or separating the razor body into components which expose the trimming wand.

A distraction device for moving a one-part or two-part or separated bone apart in order to extend or bridge a bone gap. The device is optionally provided in the form of an intramedullary pin, which can be inserted into a medullary space of a bone and which has at least two elements that can be axially moved in relation to one another. The first element is joined to the second element via at least one detent device for securing a distraction movement, and a pushing module for distracting the first element is assigned to the second element and is joined to the second element in a manner that enables it to be locked.

In an internal combustion engine having a pair of balancer shafts (53, 54), an engine torque is transmitted from a crank gear (28) to an oil pump gear (74) on a drive shaft (73) of an oil pump (71) via a first idler gear (84) and the first balancer shaft gear (64). The engine torque is also transmitted to a fuel pump (72) from the crank gear to a fuel pump gear (78) via the first idler gear and a second idler gear (86), and to the second balancer shaft gear (67) via the first idler gear and second idler gear. Alternatively, the engine torque may be transmitted to the fuel pump from the crank gear to the fuel pump gear via the first idler gear, second balancer shaft gear and second idler gear. As the oil pump gear is actuated by the crank gear via the first idler gear, the oil pump gear is not subjected to the loading caused by the balancer shaft, and hence can be made of a compact and light-weight gear. Furthermore, this allows the various gears to be arranged in an efficient (in terms of the overall weight for the given mechanical strength requirements) and compact manner.

A guide tongue (10) intervening between a pair of side slots (11) and protruding forwards from the lug (7) is inserted in between the legs (17) spaced sideways, the slots (11) fitting on the legs at the same time. A pair of bridges (19) continue from the female housing (4) to lateral ends of the push lever.
