Title: Wavelength stabilisation method e.g. for optical transmission systems
Inventor: HILLEBRAND JOACHIM
IPC: G05D25/02
Filed: 1999-10-29
Abstract: A method of wave length stabilisation of light (L1) of a light source (LQ1), in which at least one part of the light (L1) is passed to a filter with a bandpass-type transmission point at the wavelength of the light. By means of two optoelectronic transducers (W), subordinate to the bandpass filter, two electrical output signals (A1,A2) are generated and are passed to a control device (STG), at the output of which a control signal obtained by means of comparison of the two electrical output signals (A1,A2) is outputted and the light source (LQ1) is influenced in such a way by the control signal, via the control input, that its light (L1) wavelength is stabilised. For stabilising light (L2) of at least one additional light source (LQ2), a passband filter (F) with a further bandpass-type transmission point at the wavelength of light of the additional light source is used as a passband filter. The input of the passband filter (F) is switched over from one light source to the other light source and from the output of the control device (STG) a further control signal (SS2) is outputted to a further control input of the additional light source (LQ2).

Patent EP-1136830-A1 (EP)
Inventor: KNIFFLER OLIVER
IPC: G01R23/15
Filed: 2000-03-22
Abstract: The invention relates to a frequency sensor and to a method for monitoring the frequency of digital signals for which the period (TIN) of an input signal (IN) is evaluated. A time base is provided by a counter (BC) which is commutated by an internal clock signal (int_clk). The minimum and maximum frequencies (Fmin, Fmax) of a permitted frequency range are established using the corresponding period (Tmin, Tmax) and are determined with two predetermined values (nL, nH) which, multiplied by the period (Tclk), give the minimum and maximum period (Tmin, Tmax) of the input signal (TIN). A status memory (FSM) of the frequency sensor has three states, an alarm status (1L) for a too low frequency and an alarm status (1H) for a too high frequency being provided in addition to a normal status (0). The device switches to the status (1L) when a count variable reaches the value (nL) and to a status (1H) when the count variable is less than (nH) and a rising edge has been detected. The counter (BC) is reset when the edge rises or falls, respectively.

Abstract: A toast oven is controlled by a microprocessor that is
programmed to selectively determine each toasting time
in accordance with a user selected toasting requirement
and with an initial oven temperature. In this way the
toasting time is automatically adjusted to take into
account the oven temperature at the beginning of each
toasting cycle. The user therefore does not have to make
subjective manual adjustments to produce consistent
toasting results. A time display on a panel 13,
controlled by the microprocessor, indicates the
remaining toasting time during each toasting cycle.

Abstract: The invention relates to flow control in data transmission in telecommunications systems, particularly in wireless telecommunications systems. In the present invention flow control information is tunnelled over a connection leg which does not support flow control on a lower transmission protocol layer underlying a user level. The nodes at the both ends of the leg are arranged to use the flow control information to control the data flow on the lower transmission protocol level of the leg. In other words, the transmission of new data on the lower transmission protocol level is ceased or the data rate decreased when the flow control information activates the flow control in the transmitting node, and similarly, the transmission of new data on the lower transmission protocol level is restarted or the data rate increased when the conveyed flow control information deactivates the flow control.

Abstract: In a conveying system with rail-like guide means (2) and conveying means (1) movable along the guide means (2) independently of one another, a displaceable rail element (5.1-5.4) is provided for a changeover from serial to parallel conveyance. The displaceable rail element (5.1-5.4) connects in a first position with an essentially stationary rail element (3). In this first position it is filled with conveying means (1) being supplied in series along the stationary rail element (3). The conveying means (1) are then blocked on the displaceable rail element (5.1-5.4) and the displaceable rail element (5.1-5.4) is displaced in essence transverse to its length, thereby conveying the conveying means in parallel. For a changeover from parallel to serial conveyance, the displaceable rail element (5.1-5.4) is brought into a second position once again transverse to its own length, in which second position it again connects with an essentially stationary rail element (4, 4') and the conveying means (1) are unblocked and conveyed away in series from the displaceable rail element (5.1-5.4) along the stationary rail element (4, 4'). Advantageously, a plurality of displaceable rail elements (5.1-5.4) is arranged in parallel and displaced simultaneously along a closed in itself displacement path. During parallel conveyance, conveying means (1) are loaded with objects (11), objects are unloaded from conveying means and/or objects (11) loaded on conveying means (1) are processed, buffered or intermediately stored.
