Abstract: Methods and systems for timing analysis and optimization of asynchronous circuit designs are disclosed. Registration stages are placed between combinational logic circuits. For timing purposes, the registration stages are modified to have a duplicate set of pins. New paths are formed in the circuit for the purposes of timing analysis. The paths are analyzable by timing tools. Once the timing analysis is complete, the paths are reverted to original paths, and new devices are selected for the circuit design based on results of the timing analysis. An updated design is sent for manufacture, based on the timing analysis and optimization of the asynchronous circuit.

Abstract: A chemical, biochemical or biological analysis system and method including: a surface acoustic wave (SAW) actuator (6) including a piezoelectric substrate (9) and at least one interdigital electrode (17) located on a working surface (11) of the piezoelectric substrate (9), the SAW actuator generating travelling SAWs in the working surface when an electrical signal is applied to the interdigital electrode; at least one reaction chamber (19) located on the working surface of the piezoelectric substrate; a light detector (16) for detecting luminescent, fluorescent or phosphorescent emissions within the reaction chamber; a reagent flow line (29) for providing a flow of reagent through the reaction chamber; a test sample supply line (29) for supplying a test sample to the reaction chamber; wherein the SAW actuator can generate travelling SAWs within the working surface to thereby induce chaotic micromixing, convective transport, concentration or combinations thereof of the test sample and the reagent contained wit

Abstract: A surgical instrument is provided having articulating, distal end rotation and tip rotational functions. The articulating function includes a wheel rotatable relative to a handle of the surgical instrument and operable to move an articulating section of the surgical instrument from a neutral or straight position to an articulated or bent position. The wheel incorporates a groove in the form of an Archimedes spiral to drive the articulating section between the neutral and bent positions.

Abstract: A gravity-based angle sensor apparatus includes an outer housing (which may be incorporated into a carpenter's level or other reference frame) that contacts or is fastened to a workpiece, and a sensor assembly rotatably mounted within the outer housing. The sensor assembly includes a frame having internal cavities for supporting a LED light module and a sensor responsive to the orientation of the sensor assembly. The sensor electrically bridges two terminals of the LED light module to activate an LED indicator lamp when the sensor assembly has a reference horizontal orientation.

Abstract: A shaving device comprising a head assembly having a support member and a blade cartridge. The support member is configured to be detachably coupled to a handle. The blade cartridge has a first and a second face wherein at least one of the first or second faces comprises at least one razor blade. The blade cartridge is configured to be rotatably coupled to the support member about a pivot axis such that the blade cartridge is pivotable by a user to select one of the first or second faces.

Abstract: System, methods, and computer-readable media. A method includes maintaining an original image of a mail piece in a local image server and generating metadata corresponding to the original image by the local image server. The method includes transmitting the metadata to a regional image server over a network. The method includes receiving a request for the original image from a second system, and transmitting the original image to the second system in response to the request.

Abstract: The invention provides, in various embodiments, systems, devices and methods relating to ex-vivo organ care. In certain embodiments, the invention relates to maintaining an organ ex-vivo at near-physiologic conditions.

Abstract: An ammunition cartridge assembly including a case and a projectile positioned along a longitudinal axis towards the front end of the case. An endcap coupled to the front end of the case is adapted to retain the projectile entirely within the case. A primer is positioned along the longitudinal axis towards the base end of the case. A primer support is coupled to the base end of the case and is adapted to support the primer within the case. A groove is located on the interior surface of the primer support into which the primer expands under pressure during firing. Under firing pressure, the primer is deformed to create a retaining ring that locks the primer to the primer support after the pressure is released. The cartridge assembly includes at least one obturating lip seal to seal at least one of the endcap or the primer support to the case.

Abstract: System, methods, and computer-readable media. A method includes transporting a mail piece, and during transport, determining physical dimensions of the mail piece. The method includes, during transport, determining a density profile of the mail piece using an x-ray scanner and determining a weight for the mail piece according to the physical characteristics and the density profile. The method includes selectively separating the mail piece during transport based on the determined weight.

Abstract: A pump for use in anal irrigation includes a control unit integrated in the pump. The control unit includes a cylindrical housing element and a valve element fitted in the housing. The valve element and the housing element are adapted for rotating with respect to each other between a position allowing the pump to pump air into a balloon, a position allowing the pump to pump air into a reservoir bag and an evacuation position. The control unit is actuated by a handle attached to the rotatable valve element. The handle extends radially out from the rotatable valve element and the cylindrical housing.
