摘要:
A battery pack according to the invention has a housing, at least one rechargeable battery cell, and at least one temperature sensor that is attachable in a thermally conductive fashion to the rechargeable cell. At least one clamping element is provided, which cooperates with the temperature sensor in such a way that it is possible to attach the temperature sensor to the rechargeable cell in a thermally conductive fashion.

A method and an apparatus for production of yarn by friction spinning is disclosed. The friction spinning method employs a perforated friction spinning drum towards which a fibre feed passage projects. An opening roller, known from the open-end rotor spinning process, feeds separated fibres into the fibre feed passage, which fibres are taken up by a transport air flow in the fibre feed passage. This transport air flow is produced by the perforated friction spinning drum which is subjected to underpressure. Fibres leaving an opening of the fibre feed passage are laid in an inclined disposition on the perforated friction spinning drum and transported in this disposition towards a yarn end forming at a yarn formation position. The spun yarn is withdrawn by a withdrawal roller pair. Advantageously, a second friction spinning drum is provided parallel to the first perforated friction spinning drum to cause the fibre twisting-in process to take place in a more accurately defined manner.

The invention relates to a method for reduction of the power consumption of a mobile data memory with a non-contact data transmission by means of a read/write device. According to the invention, the mobile data memory, containing at least one energy store and user, is supplied, at least during a cyclic inactive idle mode, with a first clock frequency from a first oscillator and, for data receipt at least during a cyclic request time, with a second higher clock frequency from a second oscillator. The second clock frequency is determined above all for data modulation of a received signal, obtained from the reception antenna or from a combined transmission/reception antenna on the mobile data memory. The invention further relates to a mobile data memory and an identification system with at least one read/write device and one mobile data memory. The advantage of requiring no battery exchange during the life of the mobile data memory is thus conferred.
摘要:
A method of diagnosing an electronic connection open circuit includes measuring a received signal strength and determining the status of the electronic connection in response to the received signal strength. An open circuit fault signal is communicated where the received signal strength is below a desired signal strength. A user corrects the open circuit fault in response to the detection of an open circuit.

A passive start and entry system (PASE) monitors several RF frequencies to detect a fob signal and for noise at each of the several frequencies. When the PASE system detects noise on the default frequency another RF channel is selected for communication. A vehicle unit sends a signal to a fob indicating which frequency the fob should use to transmit. The fob resets an RF sender to the selected frequency. At the same time the vehicle unit resets the RF receiver to receive on that frequency.
摘要:
A receiver for receiving radio frequency signals from a remote keyless entry system and another system includes a low noise amplifier for amplifying and increasing the range and sensitivity of the receiver, such that the receiver may receive signals at increased distances. A gain of the low noise amplifier is selectively controlled to cycle from a first gain level that provides for increased sensitivity and a second gain level that provides a lower sensitivity and a greater dynamic range or larger signal capacity.
摘要:
A friction spinning machine comprising a perforated roller (6) and an imperforate roller (19) is so designed that high-quality yarn can be produced in various sizes and with adequate strengths at a relatively high rate of output. The adjustment parameters necessary to solve this problem are specified in detail, more particulary those determining the position, orientation and shape of the fibre feed duct (5).
摘要:
A housing for accommodating at least one rechargeable battery cell, having a terminal region for the electrical contacting of the housing to a device that is operated with an electric motor, in particular to a hand tool, and having at least one connecting line at one side of the at least one rechargeable battery cell, with which the at least one rechargeable battery cell is at least mediately electrically contacted at a pole, the at least one connecting line being guided in particular parallel to the extension of the rechargeable battery cell on the side of the rechargeable battery cell situated opposite the point of connection to the rechargeable battery cell. The housing has a separate cable channel in which the at least one connecting line is guided so as to be spatially separated from the at least one rechargeable battery cell.
