Abstract: The present application describes providing an attestation level to a received communication. The attestation level may be used to communicate a level of security to a network or a called party that receives the communication. The attestation level associated with the communication may indicate to a destination network and/or recipient that the phone number associated with the communication is secure and/or the telephone number has not been spoofed.

Abstract: A fixed-wing unmanned aerial vehicle (UAV) includes a propeller gimbal operably coupled to the body of the UAV at the forward end and the propeller gimbal is configured to pivot the propeller about a gimbal pivot axis to change a propeller angle. A controller of the UAV may be configured to control an attitude of flight of the UAV by controlling operation of the motor, the propeller gimbal, and the control surface assembly. The controller may be further configured to determine in-flight trajectory modifications that may require high maneuverability via high angle-of-attack attitudes of flight that are implemented via the propeller gimbal and trajectories determined from a dynamics model of the fixed-wing UAV.

Abstract: The cooling air flow path extends from a blower through a tapered input duct to a large plenum chamber which coaxially surrounds and extends over the top of the deposition apparatus. From this plenum chamber cooling air flows coaxially downward over the surface of the quartz bell jar which forms the reaction chamber, and radially inward through the banks of radiant heater lamps coaxially surrounding the bell jar. Each bank of heater lamps is readily removed for servicing by being rotated into an open position about a pivot axis extending along one verical edge. From the open position, the bank can be slid sideways in slots in the supports and removed from the apparatus.

Abstract: A suspension system for hanging a susceptor inside a reactor for processing semiconductor wafers. A hanger is provided with a flange at its lower end for supporting the susceptor. A collar has an internal flange which engages with another flange at the upper end of the hanger. The collar flange and the hanger flange each have a trucated, conical contact surface which are in substanitally continuous contact with each other. The mating flanges permit the susceptor to self-center and provide for different rates of thermal expansion of the collar and hanger.
