Providing forward secrecy in a terminating TLS connection proxy
An infrastructure delivery platform provides a RSA proxy service as an enhancement to the TLS/SSL protocol to off-load, from an edge server to an external cryptographic server, the decryption of an encrypted pre-master secret. The technique provides forward secrecy in the event that the edge server is compromised, preferably through the use of a cryptographically strong hash function that is implemented separately at both the edge server and the cryptographic server. To provide the forward secrecy for this particular leg, the edge server selects an ephemeral value, and applies a cryptographic hash the value to compute a server random value, which is then transmitted back to the requesting client. That server random value is later re-generated at the cryptographic server to enable the cryptographic server to compute a master secret. The forward secrecy is enabled by ensuring that the ephemeral value does not travel on the wire. |

Active cooling of a motor having an integrated cooling channel
A motor, comprising an electronics housing having integrated motor electronics, a stator, and a rotor. The stator comprises a stator bushing and a laminated stator core having motor windings. The stator bushing is arranged axially between the electronics housing and the rotor. The motor according to the invention has an air-conveying element connected to the rotor in a rotationally fixed manner and at least one axially extending passage opening arranged in the stator bushing. The air-conveying element is arranged axially between the stator bushing and the rotor and has a circumferential axial intake opening on the side of the stator bushing. During motor operation, the air-conveying element sucks in an axial volumetric air flow at an external wall of the electronics housing through the intake opening and the passage opening. |

Dual rack output pinion drive
The dual output pinion rack drive includes an epicyclic gearbox which permits the division of power of a single motor to first and second spur output pinions which are subjected to slightly different loading conditions based on rack geometry, rack tolerances and gear tolerances. A motor drives an input sun gear which drives planet gears which drive large and small ring gears in opposite rotational directions at similar torque levels while the carrier floats rotationally. None of the gearbox components, the sun gear, the planet gears, the large ring gear, the small ring gear, the planet carrier, and the housing are fixed rotationally. Each ring gear couples to first and second spur output pinions, respectively, and power is transferred through intermediate gear reductions and final planetary gear systems to first and second rack driving output pinions rotating in opposite directions driving the platform up a central rack. |

Motor connection module for suppressing connecting defects
A motor includes a motor unit, a gear housing coupled to the motor unit, and a connector module including a connector housing coupled to the gear housing. The motor unit includes a rotation shaft and a power terminal. The gear housing accommodates a deceleration mechanism that outputs decelerated rotation of the rotation shaft. The connector terminal and the circuit substrate are fixed to the connector housing. The power terminal is connected to a socket of the connector terminal when coupling the connector housing to the gear housing. The connector terminal includes a fixed portion fixed to the connector housing, a substrate connecting portion connected to the circuit substrate, and a supported portion located closer to the socket than the substrate connecting portion. The connector housing includes a terminal supporting portion that supports the supported portion from the rear in the coupling direction. |

Radially offset motor control housing
A motor comprising a rotor, a stator, a motor shell, a pair of motor endshields, and a controller housing is provided. The rotor is rotatable about an axis. The stator presents opposite axial ends. The motor shell extends around the axis to at least partly circumscribe the rotor and stator. Each motor endshield is positioned adjacent a respective one of the stator ends and provides support for the rotor. The fastener extends through and interconnects the stator and endshields. The controller housing defines an electronics compartment positioned radially outside the motor shell. The controller housing includes a connector that receives the fastener so as to fix the controller housing to the stator and endshields. |
