Abstract: Controlling an actual slip of at least one driven axle of a motor vehicle with at least one axle having at least one wheel and a one drive unit for providing a drive torque for the axle and for the wheel can be carried out by a control device for controlling the drive unit. The control device can be configured for establishing a first actual speed of the motor vehicle; establishing a second actual speed of the at least one wheel; calculating a target speed of the at least one wheel for the established first actual speed taking into account parameters; determining an actual slip of the at least one wheel with respect to a substrate on which the motor vehicle is being moved; when the actual slip exceeds a defined first limit slip, generating a limit torque by which the drive torque produced by the drive unit is adjusted.

Abstract: A method of bootstrapping a device by a bootstrap server, the method comprising: receiving, at the bootstrap server from the device, bootstrap data to enable the bootstrap server to determine that the device is to be provisioned with a device account identifier; verifying, at the bootstrap server, that the device is eligible to obtain a device account identifier based on or in response to the bootstrap data; obtaining, at the bootstrap server, a device account identifier assigned to the device based on or in response to the determination that the device is eligible; provisioning, from the bootstrap server to the device, first credential data comprising the device account identifier assigned to the device.

Abstract: There is disclosed a computer implemented method of bootstrapping a device by a bootstrap server, the method comprising: receiving, at the bootstrap server, credential data comprising a token and certificate data; verifying, with the bootstrap server, whether the token is legitimate; verifying, with the bootstrap server, whether the certificate data is trusted; responsive to verifying that the token is legitimate and that the certificate data is trusted providing, from the bootstrap server to the device, resource credential data to enable the device to authenticate with a first server.

Abstract: A method for operating an electrical machine is used to calculate a value of a first torque which can be provided at a maximum by the electrical machine in a future interval, wherein, by limiting the torque which is provided in the interval to the value, overheating of at least one semiconductor, which is required for transmitting the electrical power, due to a power loss is prevented and/or the threat of overheating and the onset of derating is diagnosed and therefore prevented.

Abstract: A portable handle for rehabilitation of upper extremities to be used in rehabilitation to restore motility of the upper extremities of a patient that requires it, which consists of: a main body that supports structurally the portable handle for rehabilitation of upper extremities, which is hollow inside; means of application of force or pressure located in the front face of the body and are connected in a support that fastens them; a support zone located in the posterior part of said main body to provide a better grip to the user's hand; information processing means located inside the main body and located in a contiguous manner to the means of application of force or pressure; a mean of communication to transmit the magnitude of the force or pressure applied by the means of application of force or pressure; and the means of power supply to allow the operation of the means of processing of information.

Abstract: A valve assembly (20) including a valve body (24) and a position-indicating knob assembly (28) is provided wherein the assembly (28) indicates three different valve positions, namely valve closed, partially opened and full open positions. The preferred assembly (28) includes a rotatable knob (44) including a viewing port (80) therein, together with an indicator ring (40) having three differently colored regions (62-66) corresponding to the different valve positions. A coupling assembly (42, 80, 70, 90) operably couples the knob (44) and indicator (40) so that the individual colored regions (62-66) come into view through the port (80) when the valve body (24) reaches the different valve positions. The assembly (28) is particularly useful with valves requiring greater than one revolution between valve closed and valve full open positions, such as valves used in conjunction with emergency oxygen cylinders on aircraft.

Abstract: An improved crew oxygen mask and stowage assembly combination (10) is provided including a stowage box (12) equipped with a door (22), with a crew mask assembly (14) made up of a mask (48), gas-conveying tubing (50) and valve unit (46). The box (12) also includes a valve-controlling switch lever (44) for selective gas-on or gas-off operation of valve unit (46). In normal conditions, the mask (48) and tubing (50) are stowed within box (12) with lever (44) oriented in the gas-on position, so that the tubing (50) is pressurized and mask (48) may be quickly pulled from the box (12) and used. After such use, the switch lever (44) is shifted to the gas-off position, causing the tubing (50) to be depressurized; this allows easy restowage of the tubing (50) and mask (48) within the box (12). However, when door (22) is closed, the switch lever (44) is cammed back to the gas-on position, thereby repressurizing tubing (50) and returning the combination (10) to a full-ready condition.
