Abstract: A method, apparatus and computer program product to detect whether specific sensitive data of a client is present in a cloud computing infrastructure is implemented without requiring that data be shared with the cloud provider, or that the cloud provider provide the client access to all data in the cloud. Instead of requiring the client to share its database of sensitive information, preferably the client executes a tool that uses a cryptographic protocol, namely, Private Set Intersection (PSI), to enable the client to detect whether their sensitive information is present on the cloud. Any such information identified by the tool is then used to label a document or utterance, send an alert, and/or redact or tokenize the sensitive data.

Abstract: A switched reluctance motor includes a stator, a rotor, and a planetary gear assembly. The rotor defines an internal cavity that houses the planetary gear assembly. The switched reluctance motor receives input and provides output through a common single shaft. The shaft is part of a vehicle driveline and can be positioned to provide driving input to a transmission or drive axle, for example. The planetary gear assembly includes a planet carrier that is fixed for rotation with the shaft and a sun gear that is coupled to the rotor. The planetary gear assembly allows the rotor to rotate at a higher speed than the shaft such that the switched reluctance motor can operate more efficiently for low speed vehicle applications.

Abstract: A simple parking brake includes an electric motor having an internally threaded nut. The internally threaded nut receives an externally threaded shaft. The shaft is pinned to a lever, such that it cannot rotate. The shaft thus moves linearly when the electric motor drives the nut to rotate. As the shaft moves, it drives the brake actuator between a parking position and a release position. A control supplies a pulse to drive the motor in the appropriate direction and for the particular appropriate distance. The pulse length is preferably selected to be longer than that necessary to move the shaft the necessary distance. The motor is preferably sized to stall once the desired park or open position is achieved. In this manner, a simple control is able to control the motor.

A plurality of connecting walls extends between the inner and the outer peripheral walls. The connecting walls cooperate with each other to define a plurality of discrete cooling passages within the cooling space of each jacket portion. First and second end caps are mounted to the plurality of jacket portions to enclose the plurality of discrete cooling passages such that a continuous cooling loop is provided through the plurality of jacket portions and the first and second end caps.

Abstract: A force sensor is incorporated into a disc brake, and is operable to sense the point of force application increase during application of the disc brake. The force will increase sharply once the brake pad initially contacts the rotor. The sensor is able to determine the point of this force increase, and provide this information to a control. The control powers an electric motor for providing electric motor adjustment of the position of the piston which drives the brake pad, to compensate for wear. In a preferred embodiment, the sensor includes a protective cover with a thin anvil between the cover and the sensor. The anvil is operable to transmit the force, and limit the force applied, to protect the sensor.

Abstract: A parking brake system pneumatically actuates an air cylinder to mechanically lock a wheel brake in an applied position in response to a parking demand request. The parking brake system includes a dual hand control that has an electronic control element and a pneumatic control element. The electronic control element communicates with an electronic braking system control unit and the pneumatic control element communicates with a parking brake air reservoir. When the dual hand control is moved to a park position, the electronic control element generates an electronic control signal that applies a parking brake force to the wheel brake. The pneumatic control element generates an air signal that is sent to the air cylinder. The air cylinder includes an extendable shaft that supports a lock member. The air signal moves the lock member into engagement with a brake operating member to lock the wheel brake in the applied condition.
