Title: Limiting amplifier for PSK receiver
Inventor: DURVAUX MARC MARIE GHISLAIN
IPC: H04L27/233
Filed: 1992-10-16
Abstract: The present receiver includes a radiofrequency part (RF) coupled to a limiting amplifier (SL) which is in turn coupled to a demodulation means (DM) which recovers a digital signal from a received signal obtained by modulating a carrier signal with this digital signal. 
     The limiting amplifier (SL) has an input-output characteristic which is substantially linear for smaller input signals and which strives with a decreasing gain towards a limit value for larger input signals. Due to this input-output characteristic smaller received signals are treated linearly upto the demodulation means (DM). The latter can therefore for these signals compensate for a specific spectrum shaping of the digital signal performed before the actual modulation. In this way the receiver will perform in a nearly optimal way resulting in low bit error rates. 
     For larger received signals the limiting amplifier (SL) is non-linear and such compensation is consequently without effect resulting for these signals in a performance degradation. The latter however is acceptable because these signals are naturally demodulated with less errors.

Patent EP-0549125-A1 (EP)
Inventor: MEDIAVILLA RICARDO
IPC: H04L25/40
Filed: 1992-11-20
Abstract: Improved jitter performance is realized in a desynchronizer for obtaining an asynchronous digital signal, e.g., a DS3 signal, from a received synchronous digital signal, (from 101), e.g., a SONET STS-1 signal. The improved jitter performance results from the use of a unique dynamic bit leaking arrangement (105) in conjunction with a digital phase locked loop (109,110,111) and desynchronizing elastic store (104). An optimum bit leak interval is obtained by controllably leaking a greater number of shorter interval STS-1 bits than the number of received pointer adjustment bits. Additionally, the effect of random pointer adjustments and the superposition of randomly received pointer adjustments on a periodic sequence of received pointer adjustments is minimized by employing a "static" queue of pointer adjustment bits to be leaked. The queue is dynamically maintained at its "static" count so that there are always bits in the queue to be leaked at the desired optimum bit leak interval even in the presence of randomly received pointer adjustments.

Abstract: This invention relates to a double-bulb halogen lamp with a halogen lamp in the external bulb and a lighting system using the same lamp, and more particularly to a double-bulb halogen lamp in which an infrared-ray reflecting film formed on a halogen lamp and a cylindrical external bulb are combined. The invention is characterized by comprising a halogen lamp (1) which has a filament (6) placed in a tubular bulb (2) on whose surface an infrared-ray reflecting film (8) is formed, so that the filament (6) may be almost on the central axis of the bulb (2), and which seals halogen gas in it, and a cylindrical external bulb (10) in which the lamp is placed. With this arrangement, the infrared-ray reflecting film (18) formed on the halogen lamp (1) cuts off the infrared rays emitted from the lamp, so that the cylindrical external bulb (10) is placed the closer to the lamp and the temperature distribution on the external bulb (10) is made uniform. These features enable the entire lamp device to be made more compact.

Abstract: In the radio data system, digital information (AF code and/or PI code) is transmitted within a broadcast signal, from which information those alternative transmitting frequencies can be directly picked up or derived on which the program signal of the current received frequency can also be received. The alternate transmitting frequencies to the current receiving frequencies are found by analysing the AF code and/or the PI code. Thus, a receiving section of the receiver can be successively tuned over a short time to the alternative frequencies whilst determining the reception quality of each alternative frequency and for the current received frequency. The frequency which currently offers the best-possible reception quality is selected as optimum receiving frequency. The reception quality is evaluated by means of the program signal distortion alone or in addition to the received field strength, the bit errors found in the RDS data signal being used as a measure of the program signal distortion. To improve the reception quality, the alternative frequencies in each case transmitted as frequency pairs together with an associated transmitter operating frequency are addressed, and possibly stored, as determined by the transmitter operating frequency immediately preceding or following them in each case. At the receiving end, means for selecting another alternative frequency are provided for the case that the alternative frequency offering the currently best-possible reception only provides an acoustically distorted reproduction.

Abstract: The invention proposes a method of sealing and/or shaping a food product and apparatus for use in performing the method. Food product is placed on a support surface (10), and a moulding surface - comprising a flexible diaphragm (25) is lowered over the food product. Air pressure acting on the diaphragm applies a force to the food product for the purpose of sealing and/or shaping the food product. The arrangement produces a more random appearance to the resulting food product. A plurality of food products are acted on by a respective moulding surface which are carried from a common framework. The support surface is preferably a conveyor belt and the framework is mounted for reciprocal movement so that moulding pressure can be applied to the food product during an indexing movement of the support surface.
