A rotary module for implementing a high frequency pressure swing adsorption process comprises a stator and a rotor rotatably coupled to the stator. The stator includes a first stator valve surface, a second stator valve surface, a plurality of first function compartments opening into the first stator valve surface, and a plurality of second function compartments opening into the second stator valve surface. The rotor includes a first rotor valve surface in communication with the first stator valve surface, a second rotor valve surface in communication with the second stator valve surface, and a plurality of flow paths for receiving adsorbent material therein. Each flow path includes a pair of opposite ends, and a plurality of apertures provided in the rotor valve surfaces and in communication with the flow path ends and the function ports for cyclically exposing each flow path to a plurality of discrete pressure levels between the upper and lower pressures for maintaining uniform gas flow through the first and second function compartments.

A leak detection method for an air bed having an air chamber comprises adjusting the air chamber to a predetermined pressure level, sensing a first pressure value of the air chamber after a first time interval, sensing a second pressure value of the air chamber after a second time interval, determining a pressure change in the air chamber, detecting whether the air chamber is leaking by comparing the pressure change with a second pressure value, and displaying a leak detection indicator. In one embodiment, the second pressure value is a pressure change in a second air chamber. In another embodiment, the second pressure value is an expected pressure change of the air chamber that is calculated based upon changes in ambient temperature and barometric pressure.

A method for increasing the resolution when forming a three-dimensional article through successive fusion of parts of a powder bed, said method comprising providing a vacuum chamber, providing an electron gun, providing a first powder layer on a work table inside said vacuum chamber, directing an electron beam from said electron gun over said work table causing the powder layer to fuse in selected locations to form a first cross section of said three-dimensional article, providing a second powder layer on said work table, directing the electron beam over said work table causing said second powder layer to fuse in selected locations to form a second cross section of said three-dimensional article, reducing the pressure in the vacuum chamber from a first pressure level to a second pressure level between the providing of said first powder layer and said second powder layer.

An object execution method and apparatus is provided for executing an object based on an input pressure level with a haptic feedback indicative of an attribute of the object. An object execution apparatus may include a display unit, an input unit, and a control unit. The display unit may display at least one object. The input unit may detect a selection of an object and / or a pressure level input for executing the object. The control unit may check a reference pressure value preset for the selected object. The reference pressure value may be indicative of attribute information of the object. The control unit may compare an input pressure value of the pressure level input with the reference pressure value, and may determine whether to execute the object based on the comparison result. The input unit comprising a vibration generator may generate a vibration mapped to the reference pressure value.

A computing device with a multi-touch touch interface having a plurality of rows of contact points and a plurality of columns of contact points. For each other row of contact points, every contact point in the row is connected to form a row sensor. For each other column of contact points, every contact point in the column that is not part of a row sensor is connected to form a column sensor. The contact points that are not part of a row sensor and not part of a column sensor are connected together to form at least one shape sensor. A computing device with a multi-touch touch interface having a plurality of contact points has at least one layer of piezoresistive material, an insulating structure disposed between the plurality of contact points and the piezoresistive material, and a gap between the plurality of contact points and piezoresistive material. A method of providing multi-layered password recognition for a computing device having a touch interface first provides a passcode associated with an alphanumeric symbol to the computing device. The alphanumeric symbol is associated with a passcode pressure level. A touch load is applied to the touch interface and a measured pressure level associated with the applied touch load is determined. Then it is determined whether the measured pressure level corresponds to the passcode pressure level associated with the alphanumeric symbol of the passcode.
