Abstract: Apparatus and method for measuring the time interval
between a first event and a second event in a tester system.
First and second time measurement circuits independently
receive respective first and second events. The time
measurement circuits each includes a coarse counter clocked
by the master clock. The first coarse counter is activated
by an initial event, and the first coarse counter stops
counting upon activation of the first event. The second
coarse counter is also activated by the initial event, and
the second coarse counter stops counting upon activation of
the second event. A first fine counter clocked by the
master clock produces a count value representing the time
interval between the first event and a first leading edge of
the master clock. A second fine counter clocked by the
master clock produces a count value representing the time
interval between the second event and a second leading edge
of the master clock.

Abstract: The signal to interference and noise ratio (SINR) of wireless systems can be
improved, if not optimized, by determining operating parameters used by the base station
to substantially simultaneously control the transmit beam patterns that are each formed to
establish a communication channel between a base station and a respective one of the
wireless terminals as a function of received channel information from at least two of the
wireless terminals. In an exemplary embodiment of the invention, the weight vectors and
the power allocation employed by a base station are determined by the base station using
information supplied by at least each of the wireless terminals served by the base station,
and potentially from wireless terminals served by other base stations, e.g., in neighboring
cells to the cell served by the base station, the information from the other cells being
supplied via the neighboring cell base stations using inter-base-station
communication,
e.g., a wire line connection.

Abstract: The optical printer 1 comprises the fluorescent light-emitting
tube 2 equipped with the anode 11 in a form of dot and the rotatable
rotating filter part 15 equipped with the filters R. G. B. The film 3
is moved relative to the optical printer 1 set at a given position. The
controlling means 30 rotates the rotating filter part 15, and, in
synchronization with that, the fluorescent light-emitting tube 2 is
made to emit light by the image signal of every color of red, green
and blue. The image can be formed by moving the film one time
relative to irradiation with the light in a state of dot transmitted
selectively through each filter of red, green and blue. Since the head
is fixed and the film is moved, room for the movement of the head
which has been conventionally required is not required. Spatial
room for the slide of the filter is not required differently from the
slide-switching type-filter of the conventional art.

Abstract: This invention consists of a portable air pump that conveniently positioned close to a
fire place will accelerate the rate of combustion. 
     With this device there is no longer a need to take care of the fireplace, especially
during the first stage of the combustion process, with the use of certain traditional elements
such as a bellow; rather, this battery run device allows for an air flow to be directed to the
charcoal where the combustion is taking place, in a continuous and unoform manner, thus
allowing for the flame to become stronger. This process may take a few minutes (depending
on the quality of the wood) until the flame is so strong that the device may be switched off 
     Evidently, this process may be repeated when and as necessary, especially if the flame
is becoming weaker or if more wood is being added to the fire place.

Abstract: The present invention concerns a system for generating a band limited burst-like waveform.
The system is responsive to an information bit sequence and a burst control signal and is
essentially characterised by a constellation mapping device feeding a pair of pulse shaping
filters and a pair of appropriately controlled storage devices maintaining burst opening and
burst closing waveforms. The output of the pulse shaping filters and the storage devices are
multiplexed to produce the band limited burst-like waveform. The stored waveforms may
have a sinusoidal form, while the associated control logic may be realised by a finite state
machine. If the invention is used in a wireless transmission system, additional gating
circuitry improves the spectrum characteristics of the emitted signal. Transmission systems
employing offset modulation formats such as OQPSK can easily be implemented in this
framework. The invention more particularly applies to wireline and wireless access systems,
to satellite links, and to mobile radio communications.

Abstract: L'invention se rapporte à un système de chauffage à alimentation propre comportant une chaudière (102) servant à la production de vapeur, un dispositif d'expansion (114) conçu pour extraire de l'énergie mécanique et électrique de la vapeur et un échangeur (116) thermique conçu pour transférer l'énergie thermique issue de la vapeur à l'air ambiant. Un ventilateur (122) monté en position adjacente à l'échangeur thermique force l'air ambiant à se réchauffer devant l'échangeur thermique et à travers tout l'espace à réchauffer. Une pompe (120) électrique renvoie le condensat de l'échangeur thermique vers la chaudière. L'énergie électrique et l'énergie mécanique permettant d'actionner le ventilateur et la pompe sont fournies par le dispositif d'expansion. Ce dernier extrait l'énergie mécanique de la vapeur basse pression fournie par la chaudière de façon à faire fonctionner le ventilateur et il comporte un magnéto conçu pour produire un courant alternatif qui peut être transformé en courant continu destiné à alimenter la pompe. L'énergie électrique produite par le magnéto est également suffisante pour alimenter un robinet (154) d'admission de la vapeur dans le dispositif d'expansion et un robinet (109) de carburant conçu pour réguler le débit de carburant vers le brûleur. Dans une autre réalisation, le système comporte une chaudière (404) à eau haute pression conçue pour la coproduction d'énergie thermique et électrique. L'eau chaude à haute pression subit une expansion (420) qui se traduit par une production d'énergie mécanique destinée à entraîner un générateur et à produire, de ce fait, de l'énergie électrique. L'eau chaude et la vapeur provenant du dispositif d'expansion passent dans un condenseur (426) assurant le transfert de chaleur vers une source d'eau secondaire. Cette eau secondaire chauffée peut servir au chauffage de locaux.

Abstract: A method and apparatus of regulating cycles of a burner in a forced air system. A control unit uses a sensor at an output of a heat exchanger (22) to make measurements of a temperature of air output from the heat exchanger (22). The control unit observes temperature measurements, after the burner (24) has turned on. It initializes a confirmation interval when two consecutive temperature measurements are the same. The invention interrupts firing of the burner (24) for an interrupt interval. The interrupt interval is insufficient to allow the heat exchanger (22) to cool below a temperature useful for heating below which the circulation fan would shut off.
