Patent EP-0564937-A1 (EP)
Inventor: BAYES TERENCE
IPC: H04B7/26
Filed: 1993-03-27
Abstract: A code division multiple access (CDMA) system wherein communication between a base station and a plurality of hand sets is effected at a common carrier frequency utilising time division duplex to afford accurate power control and to obviate the 'near far' problem. Preferably a pilot signal is added to the transmissions from the base station. This is used to sound the channel, providing a measure of the channel impulse response from base station to each hand set receiver. This information is then used to set up an inverse filter, which is applied to the receiver signal prior to detection. The detrimental effects of the channel can be removed, restoring orthogonality to a received code set and thus giving optimum capacity. In the reverse link a pilot can be used to predistort each hand set signal prior to transmission, according to the unique channel impulse response measurement made at each hand set. Since the filtering operations are assumed linear the order may be interchanged, and the base station receives each hand set signal with the detrimental effects of the channel precompensated. Orthogonality between hand set transmissions is therefore achieved at the base station receiver. Capacity is therefore balanced in forward and reverse links and the constraint of power control may be somewhat relaxed.

Abstract: The invention relates to a chip-type solid electrolytic capacitor which uses a capacitor element having an anode lead (14) protruding from one end face of an anode body (12) of a valve metal. The capacitor element is covered by an insulating resin cover layer (20) except a cathode end face (10b) and the protruding part of the anode lead (14). A cathode terminal (30) is formed on the cathode end face (10b) and the resin cover layer (20) in an area near the cathode end face (10b), and an anode terminal (22) is formed on the resin cover layer (20) so as to make contact with the protruding anode lead. The anode terminal (22) is made up of a conductive layer (24) which is formed on the resin cover layer (20) only in a limited area so as not to make contact with the anode lead (14) and has a microscopically rough surface, a plating layer (26) which is formed on the conductive layer (24) and the resin cover layer (20) in the area over the aforementioned end face of the anode body (12) and covers the protruding anode lead (14) and a solder layer (28) formed on the plating layer. In the anode terminal (22) the rough surface of the conductive layer (24) enhances the adhesion of the overlaid plating layer (26), and the separation of the conductive layer (24) from the anode lead (14) eliminates the problem about different thermal expansion coefficients of the conductive layer (24) and the anode lead (14). Therefore, when the chip-type capacitor is mounted on a printed circuit board the bonding strength is enhanced.

Abstract: An electronic control for gas furnaces controls a two speed main blower fan and an induction draft fan based on inputs from a room thermostat, a high limit and an ignition control including a gas valve. The control has a circuit board having a power supply for providing 24 volts DC current source to drive DC relays and a 5 volt DC power source to power a microprocessor. 24 volt AC input signals are coupled to the input ports of the microprocessor through current limiting resistors and to AC ground through pull down resistors. AC ground is also connected to the IRQ port of the microprocessor. The output ports of the microprocessor are connected to a relay driver which in turn is connected to relays for energizing and de-energizing the fans. 
     The control calibrates itself on a continuing periodic basis to read the AC inputs synchronously at the peak of their wave and can switch the relays asynchronously based on the Real Time Clock of the microprocessor or can be switched synchronously by providing a selected delay so that contact engagement and disengagement occurs at or near the zero crossing of the AC line voltage wave form. When used with resistive loads the relays are switched in response to a signal from the microprocessor which is delayed based on the mechanical switching time constant of the relays to provide contact closure and opening at the selected point on the AC line voltage wave form. An alternate embodiment shows a feedback network used to calibrate the specific delay period for each relay upon initialization. When used with inductive loads contact closing can be effected synchronously and contact opening asynchronously.

Abstract: Methods and apparatus for controlling a conditioned space (14) to a predetermined set point temperature (58), utilizing a supply (16) of cryogen. Cryogen is drawn from the supply in a flow path (42;202) to provide a cooling mode via a heat exchanger (46;156) disposed in the flow path. A vapor motor (78) in the flow path, downstream from the heat exchanger, drives a fan (76) which moves air between the conditioned space and the heat exchanger. Heat (90) is applied to the cryogen downstream from the heat exchanger, after all cooling modes have been performed, to provide the desired fan horsepower, without interfering with a cooling cycle. A by-pass flow path (124,186) selectively directs cryogen directly to the vapor motor, by-passing the heat exchanger, to provide air circulation in the conditioned space when the temperature of the conditioned space is satisfied.

Abstract: This invention deals with a safe key distribution and authentication in a data communication network (e.g. wireless LAN type of network). 
     The network includes a network manager to which are connected, via a LAN wired circuit, one or more base stations. Individual remote stations are, in turn, wirelessly connected to an installed base station. 
     One essential function for achieving security in such a network, is a mechanism to reliably authenticate the exchanges of data between communicating parties. This involves the establishment of session keys, which keys need to be distributed safely to the network components. An original and safe method is provided with this invention for key distribution and authentication during network installation, said method including using the first installed base station for generating a network key and a backbone key, and then using said first installed base station for subsequent remote station or additional base station installations while avoiding communicating said network key.
