Title: Smoke detector
Inventor: MUGGLI JUERG
IPC: G08B17/10
Filed: 1982-11-04
Abstract: A smoke detector is disclosed having a radiation source operated in a pulsed mode. Externally of a direct radiation region of the radiation source there is arranged a radiation receiver which, in the presence of smoke or other particles emanating from a combustion process and located in the radiation region, is impinged by scattered radiation and delivers an output signal to an evaluation circuit. The evaluation circuit contains switching elements which, when the number of source output signals or pulses exceeds a predetermined threshold value for the number of source output pulses, delivers an alarm signal. Near to the radiation receiver there is arranged a reference cell in the direct radiation beam of the radiation source, this reference cell controlling the emission of radiation by the radiation source. Further, there is provided circuitry which, in the presence of a slow change in the amplitude of the receiver output pulse, adjusts an amplitude threshold value set for the amplitude of the receiver output pulse at a rate corresponding to a time-constant of more than one minute. Consequently, there is obtained an output signal of the radiation receiver which is dependent upon the smoke density and which is independent of the contamination or soiling of the smoke detector.

Title: Apparatus and method for collecting oil from water
Inventor: TARVAJNEN TEUVO RAJNE
IPC: E02B15/04
Filed: 1987-04-24
Abstract: The invention relates to preventing oil damage in open water. The invention is based on the fact that the viscosity of oil changes as a function of temperature. Fig. 1 shows the operating principle. The catamaran-type vessel is provided with two cylinders (2) which are kept at a lower temperature than the water, using cooling units (5). The oil (7) floating in the water comes into contact with the cylinder (2), congeals and adheres to the surface of the cylinder. As the cylinder rotates, the oil is transported on the surface of the cylinder until it reaches a heated collection gutter (8) where it is collected. From the gutter it is directed into a collecting tank which is located in the vessel. The dimensions of the vessels, of the cylinders, and of the cooling unit can be chosen freely according to the conditions.

Title: Method and device for speech encryption and decryption in voice transmission
Inventor: BUSHING WOLFRAM
IPC: H04K1/00
Filed: 1994-11-18
Abstract: PCT No. PCT/EP94/03693 Sec. 371 Date May 14, 1996 Sec. 102(e) Date May 14, 1996 PCT Filed Nov. 9, 1994 PCT Pub. No. WO95/15627 PCT Pub. Date Jun. 8, 1995A digitized real voice signal is converted via complex filtering into a complex signal that is subjected to sampling rate reduction, the bandwidth of the respective complex filter corresponding to the sampling rate. The complex signal is phase-modulated by means of a code signal generated by a random-number generator and additively combined with a pilot signal (likewise phase-modulated in a random distribution) to form an encrypted useful signal for transmission. The useful signal is sequentially transmitted together with a preamble for synchronization and signal equalization at the receiver end. At the receiver end, clock synchronization is forced for a phase-modulated pilot signal produced at the receiver end and equalizer coefficients for an equalizer at the receiver end are calculated from the digitized received signal after complex filtering and corresponding sampling rate reduction, during a preamble recognition phase, at which point the phase of the useful signal decryption is initialized. The encrypted, transmitted signal is separated from its phase-modulated pilot signal, which is superimposed at the transmitter end, by linking to the synchronized pilot signal, which is produced at the receiver end, and the phase-modulated, encrypted digital speech signal thus obtained is subsequently decomposed by the code signal produced at the receiving end and clockcontrolled by the preamble.

Title: Method for packaging using resin
Inventor: YAN YUEJUN
IPC: H01L21/56
Filed: 2007-07-03
Granted: 2012-01-18
Abstract: A method for packaging electronic components using resin comprises mounting a plurality of bare components 2 on a common substrate 1 separated by a gap d, individually encapsulating each component 2 with a resin packaging material, solidifying the resin and then cutting the substrate in the gaps to form separate resin encapsulated components. Holes 4 may be formed in the gaps to facilitate cutting. The invention relieves the problem of the resin splitting from the substrate due to different thermal expansions between the resin and substrate materials. This makes it possible to tightly attach the resin to the substrate, and is especially suitable for packaging of large scale bare chips.
