A pipe tool comprises a head mounted on a shaft. The head has a primary channel having a circular profile of a primary channel diameter and a secondary channel having a circular profile of a secondary channel diameter. The secondary channel diameter is smaller than the primary channel diameter. The head has an intermediate wall having an intermediate wall outside surface defining an inside boundary of the primary channel, and the intermediate wall has an intermediate wall inside surface defining an outside boundary of the secondary channel. An intermediate wall gap passes between the primary channel and the secondary channel. An intermediate wall outside corner is disposed on the intermediate wall gap. An outside wall has an outside wall inside surface bounding the external periphery of the primary channel.

A frequency generation circuit comprises a crystal oscillator (10) for providing an input frequency, a phase-locked loop circuit (28), and a programmable frequency divider (42) for frequency dividing an output from the phase-locked loop circuit. The frequency generation circuit can generate a plurality of different output frequencies for supply to respective DAB and FM tuners (50, 60, 70). The frequency generation circuit can be used, together with a baseband circuit (14), in a radio receiver (1, 2). The same oscillator (10) and phase-locked loop circuit are used to drive the baseband circuit.

A navigation arrangement for a motor vehicle includes a first motor vehicle having a navigation system for ascertaining a suggested route for the first motor vehicle and at least one second motor vehicle having a navigation system for ascertaining a suggested route for the second motor vehicle, and an Internet connection being provided between the first motor vehicle and the second motor vehicle for transmitting information concerning the navigation system of the first motor vehicle from the first motor vehicle to the second motor vehicle.
摘要:
An improved computer system bus is disclosed that transitions between addressed data transfers and handshake data transfers on the fly and that performs burst within dynamic data sizing during a data transfer sequence without prematurely terminating the sequence and that changes between synchronous and asynchronous data transfer sequences on the fly. These capabilities are accomplished by modifying the function of bus signal lines depending upon the type of transfer sequence undertaken. On the fly transition between addressed data transfer and handshake data transfer is accomplished by providing a set of DMA acknowledge signals and modifying their function according to the type of data transfer sequence underway. Burst within dynamic data sizing during a sequence is performed by taking advantage of burst transfer capabilities of the slave device, and the capability of the master device to modify data width on the fly. If the slave supports burst transfer, the bus master proceeds with a burst transfer sequence for the remaining portions of the data while shifting the data to accommodate the data width limitation of the slave device. On the fly transition between a synchronous transfer sequence and an asynchronous transfer sequence is accomplished by modifying the timing of bus acknowledge signals.

In a navigation system for a motor vehicle, the navigation system includes an off-board navigation system that is spatially separate from the motor vehicle, a wireless communication connection between the off-board navigation system and the motor vehicle to transmit a suggested route for the motor vehicle and/or a map display of the environment of the motor vehicle from the off-board navigation system to the motor vehicle, and a man-machine interface arranged in the motor vehicle, to output the suggested route or the map display to an operator of the motor vehicle, in connection or together with an item of additional information, the provision of the additional information being accessible to a third party.

A navigation system is for a motor vehicle. The navigation system includes a motor vehicle, an isolated, immobile memory node for storing navigation data, a wireless communication connections between the isolated, immobile memory node and the motor vehicle for transmitting the navigation data from the isolated, immobile memory node to the motor vehicle and a man-machine interface arranged in the motor vehicle for outputting the navigation data to an operator of the motor vehicle.
摘要:
A voice command acquisition method and system for motor vehicles is improved in that noise source information is obtained directly from the vehicle system bus. Upon receiving an input signal with a voice command, the system bus is queried for one or more possible sources of a noise component in the input signal. In addition to vehicle-internal information (e.g., window status, fan blower speed, vehicle speed), the system may acquire external information (e.g., weather status) in order to better classify the noise component in the input signal. If the noise source is found to be a window, for example, the driver may be prompted to close the window. In addition, if the fan blower is at a high speed level, it may be slowed down automatically.
