Abstract: A site access control unit (100) comprising: a structure (102) defining at least one bay (104A), wherein the bay comprises a sensor arrangement (204, 208) configured for at least authentication of a user, wherein the site access control unit further comprises control apparatus (201) configured to: cause the sensor arrangement to scan the user (408, 410); obtain authentication clearance based on authentication data from the scan (408); and transmit an egress control signal (413) to a device (228, 230), for directing the user to leave the bay, when at least the authentication clearance is obtained.

Abstract: Some embodiments are directed to a control system for a sound controller configured to transmit sounds to a vehicle passenger cabin. The system includes a downshift sensor configured to detect a downshift of a vehicle transmission, and an accelerator pedal sensor that is configured to detect whether an accelerator pedal is actuated above a predetermined threshold. A controller controls operation of the sound controller in accordance with a sound control logic that is based on vehicle engine mode, transmission gear selection, accelerator pedal position, and vehicle engine speed. The controller also controls operation of the sound controller in accordance with an audible downshift logic if the downshift sensor detects a downshift of the vehicle transmission and the accelerator pedal sensor detects that the accelerator pedal is not actuated above the predetermined threshold, the audible downshift logic controlling the sound controller to enhance engine sound transmitted to the passenger cabin.

Abstract: The present invention relates to a process for the dyeing of cellulosic fibers in the form of a comminution sheet to produce a dyed cellulose pulp comminution sheet with high moisture content. The dyed cellulose comminution sheet contains (a) a cellulose pulp comminution sheet having a cellulose content of from about 60 weight percent to about 99.9 weight percent cellulose based on the total weight of solids in the cellulose pulp comminution sheet, and a density of from about 0.3 g/cm3 to about 0.95 g/cm3; (b) a moisture content of from about 25 weight percent to about 55 weight percent, based on the total weight of the dyed cellulose comminution sheet, wherein the moisture content does not exceed bleed point of the comminution sheet; and (c) a dye.

Abstract: A modular electric motor. The modular motor includes a plurality of mechanically and electrically coupleable stator sections and mechanically coupleable housing sections. At least one stator section has conductors extending longitudinally therethrough for generating a magnetic field to impart rotative motion in a rotor. A given motor may be assembled to a variety of desired lengths by mechanically and electrically coupling the appropriate number of motor sections. This facilitates construction of a desired horsepower motor for a given application.

Abstract: A system for pumping and heating viscous fluids in a wellbore includes electrical power supplies, a switchboard, conductors, and a submergible pumping system having a pump and a submergible electric motor. The electrical power supplies are coupled to the submergible pumping system through a switchboard and conductors that supply electrical power to the motor. The electrical power supplies provide direct or alternating current and include protective circuitry. The submergible pumping system may be supplied with electrical power to motor stator windings to generate heat to raise the temperature and lower the viscosity of adjacent viscous fluids.
