Abstract: The assembly includes a docking console and a manifold. The docking console includes a cartridge support surface having a first end and a second end. The manifold has one or more wells defined therein. The docking console further includes a manifold retention bracket to releasably hold the manifold against a fluid cartridge supported on the cartridge support surface at an interface position such that the one or more wells are in fluid communication with the fluid cartridge and a biased seal bar to press the fluid cartridge against the manifold held by the manifold retention bracket. A hydrophilic porous frit disposed within at least one of the wells and is to permit liquid to flow through the outlet aperture but prevent gas from passing through the outlet aperture.

Abstract: An electric tool is provided with a second switch that is actuated in order for the tool to be used. The second switch is on a second handle that is grasped by the operator with a different hand than the hand that actuates the main trigger switch. Communication between the second switch and the tool occurs with a wireless signal indicating that the second switch has been actuated.

Abstract: A rotary power tool assembly including a hammercase an axis extending between a forward end and a rearward end, a drive mechanism housed within the hammercase, and a hammer driven by the drive mechanism to apply a rotational impact force on an anvil. The anvil includes an output shaft rotatable about the axis, a plurality of anvil jaws extending from the axis, and a flange fixedly connected to an end of the output shaft and extending radially from the axis, wherein the flange supports the plurality of anvil jaws, the flange extending over the plurality of anvil jaws. The anvil includes a magnet attached to the flange opposite to the plurality of anvil jaws. An anvil angle sensor is configured to read and interpret magnetic flux changes of the magnet and determine the position of the anvil rotating about the axis.

Abstract: A security screening installation system for use in a controlled environment is described. In an embodiment, a passive detector apparatus does not produce a magnetic field for detection and relies on detecting changes in the local magnetic field. The apparatus is: (i) battery powered; (ii) light enough to be hand carried by hand and set up by one person; (iii) comprises a single elongate housing; and (iv) operable between a packed state inside a protective case and a ready to use state outside of the protective case. The housing supports at least two magnetic sensors that define a gradiometer which is arranged to produce a signal indicative of an ambient magnetic field or gradient over a zone of sensitivity which extends away from the housing, wherein a size of the zone is large enough to contain a whole body of a person.

Abstract: An electric impact tool in which a rotating mass rotates in a forward direction to impact upon and transfer torque to an anvil, and rotates in a reverse direction opposite the forward direction in response to such impact. A direction sensor monitors the direction of rotation of the rotating mass, and a controller turns an electric motor on and off during respective forward and reverse rotation of the rotating mass. An energy storing mechanism may be used to absorb energy from reverse rotation of the rotating mass and release the absorbed energy to rotate the rotating mass in the forward direction. A controller may be used to store the angular position of the rotating mass upon each impact and turn off the motor prior to the following impact to avoid energizing the motor during stall.

Abstract: A constant power control circuit for an electrosurgical generator and a method for maintaining the electrical power output of an electrosurgical generator at a generally constant value throughout a given tissue impedance range are disclosed. The constant power control circuit and the method recognize and use the unique and simple linear characteristics associated with certain electrosurgical generator designs to monitor and control the electrical power output without having to calculate or monitor the actual output power. The constant power control circuit includes a current sampling circuit, a linear conversion circuit, and a feedback correction circuit.

Abstract: Apparatus monitors RF return current to maximize the AC signal of impedance at two return electrodes. A transformer with driving and driven windings isolates ESU and patient. At ends of the driving winding are signal and ground terminals joined to the return electrodes with capacitors returning current. An AC coupling capacitor at the signal terminal has a timing circuit in sync to the voltage wave and relative to impedance of the return electrodes. Microprocessing the voltage at the signal terminal of the driving winding watches impedance and determines if the RF return current path is adequate. Voltage detection within the timing circuit has a voltage shaping circuit. A voltage comparator after the voltage detection forms a square wave. A current detection circuit and a coupling capacitor allow AC flow to the driving winding. Current shaping circuit in the current detection circuit has a voltage comparator at the output to form a square wave.
