Abstract: A hand-portable garden, forestry and/or construction processing device has a cutting tool, an electric drive motor, a motor operating element, and a control device. The cutting tool is designed for cutting through work. The drive motor is designed for driving the cutting tool. The motor operating element is user-adjustable over an adjustment range from a minimum setting to a maximum setting. The control device is designed for controlling a target speed of the drive motor in accordance with a setting of the motor operating element in at least one first operating mode and one second operating mode. In the first operating mode, the target speed increases over at least one segment from a minimum of 0.5 times the adjustment range as the setting increases, wherein the increase changes over the segment by a maximum of 60%. In the second operating mode, the target speed is a minimum of 0.9 times a maximum target speed of the second operating mode as the setting increases from a maximum of 50% of the adjustment range.

Abstract: A process identifier transition monitor captures and assesses activities associated with a microprocessor or a microcontroller. Monitoring and assessment is performed by detection of process identifier transitions, which may be driven by an occurrence of one or more activities, such as execution of application software, system hardware mechanisms, or processor-internal mechanisms. Process identifier transitions are assessed to determine whether such transitions were expected. If a detected process identifier transition was not expected, then a system alert may be transmitted or some other appropriate response taken within the system.

Abstract: To suppress tuning noise interferences, and particularly transients, such as whistles and the like, especially in FM receivers during returning of the receiver, an inter-station retuning muting circuit is, in accordance with the invention, modified by including therein a switchable filter (2) having a low-frequency cut-off (f.sub.g2) which is higher than the frequency of noise interference due to retuning of the receiver, the filter being switched to the higher frequency cut-off level for a period of time (T.sub.E) which exceeds the normal muting time (T.sub.E) of FM receivers.

Abstract: To prevent overriding an electronic car radio theft disabling system by connecting an external battery to a car radio prior to theft thereof, the radio includes a measuring circuit (7, 7') measures the impedance of a connected accessory, for example a loudspeaker or loudspeaker system (8), and if the impedance of connected loudspeaker does not match the impedance stored in a memory (5) of the car radio, operation of the radio is inhibited until the appropriate code word--known only to the proper owner--is reinserted.

Abstract: Upon unauthorized removal of a car radio (2) from the chassis (C) of a car, a memory (5) which has a code stored therein is changed and inhibits operation of the car radio. The memory is retained in a predetermined memory state either by continuously receiving data inputs, for example from a potentiometer slider of a potentiometer (6), or data entered into an RAM energized only upon being properly connected in the vehicle. Alternatively, a user may enter a code, for example by operation of station selector buttons (4) of the car radio (2), and upon operating a set code switch (9), which code is destroyed upon removal of the radio, or upon failure to enter the correct code from time to time.
