Abstract: A protective device, in particular a shin guard, includes one or more stacked layers that are coupled together and define a first face for contacting the body of a user and an opposite second face for facing outward, with elements engaging the protective device with an anatomical zone. At least one layer is made of a polymeric gel having an elasticity sufficient to return to the initial condition after a deformation caused by an impact, or alternatively of an expanded plastic material that is deformable and elastically compressible. The first face has a three-dimensional conformation, with the areas of contact with the user's body projecting outwards toward the user's body to a greater extent than other areas that are recessed, the recessed areas being interposed between the protruding areas and failing to come in contact with the user's body in the absence of deformations caused by an impact.

Abstract: A system and a method for communicating over a Bluetooth Low Energy (BLE) connection in a vehicle. The method includes the steps of: establishing a Bluetooth Low Energy (BLE) connection between a mobile device and a BLE system in the vehicle, wherein the establishing step includes receiving first credentials of the mobile device at the BLE system; providing second credentials to the mobile device from the vehicle, wherein the second credentials are different than the first credentials; and receiving a message from the mobile device that is encrypted using the first and second credentials.

Abstract: A mobile communication system that includes a vehicle and a mobile device is provided. The method pertains to revoking communication control privileges of the mobile device previously authorized to control the vehicle. The method includes the steps of receiving a revocation request at the vehicle via a user interface device, the revocation request including a request to revoke the communication control privileges of the previously authorized mobile device, wherein the control privileges includes a capacity to remotely command at least one of a plurality of vehicle functions; and based on the revocation request, revoking at the vehicle the communication control privileges of the previously authorized mobile device.

Abstract: An oil-lubricated automotive volumetric vacuum pump includes a circumferential pump room wall surrounding a pump room. A rotor comprises a rotor body with an oil receiving cavity and a guiding slot. The rotor body is adjacent to the pump room wall. The rotor rotates inside the pump room. A vane with a vane body and a vane end portion shifts in the guiding slot. The rotor body, the vane, and the circumferential pump room wall define at least two pump chambers. An oil discharge channel with a flow opening in a plane is arranged at the vane end portion of the vane and/or at the guiding slot. The flow opening opens so that oil can flow from a pump chamber through the oil discharge channel to the oil receiving cavity only in a retracted position of the vane end portion during a final compression phase of the respective pump chamber.
