Title: Registration of mobile packet data terminals after disaster
Inventor: WRIGHT ANDREW S
IPC: H04L69/40
Filed: 1997-05-06
Granted: 2007-11-13
Abstract: Registration attempts by a terminal using a contention protocol to communicate with a central system are controlled by transmitting a registration index from the central system to the terminal at specified temporal periods, and modifying the value of the registration index when the terminal should attempt to register with the central system. A mode flag is transmitted from the central system to the terminal at predetermined temporal intervals, and the value of the mode flag is modified when the central system is recovering from a disaster so that the terminal refrains from immediately attempting to register with the central system.  During disaster recovery, the terminal is able to associate itself with one of a plurality of sub-intervals. The central system transmits a sub-interval designator to the terminal at regular temporal periods during disaster recovery. The central system modifies the value of the sub-interval designator after a predetermined number of the regular temporal periods. The flow of registration attempts by a community of terminals is smoothed from a situation wherein essentially the entire community of terminals is contending to register after a disaster to a situation wherein subsets of the community try to register in respective sub-intervals after the disaster.

Abstract: The invention is directed to improved automatic dispenser apparatus for dispensing sheet material and the like without contact between a user and the dispenser. Proximity detection apparatus is provided to detect the presence of a user in a detection zone generated outside the dispenser. Control apparatus controls actuation of the dispenser in response to the detected user. Preferred forms of the proximity detector include a sensor and a signal detection circuit operatively connected to the sensor. The sensor includes conductors configured to have a capacitance and positioned such that the capacitance is changed by the presence of a user within the detection zone. The signal detection circuit detects the change in capacitance and is provided with an oscillator having a frequency which is affected by the sensor capacitance and a differential frequency discriminator which detects changes in the oscillator frequency. The control apparatus receives the detected frequency change and generates a signal provided to actuate the dispenser to dispense the material. The dispenser control apparatus controls dispenser operation responsive to decreases in battery voltage which occur during the life cycle of the batteries and controls dispenser operation when the batteries near the end of such life cycle. Such control apparatus may be used with any type of battery powered dispenser, including hands-free dispensers and dispensers actuated by direct physical contact with the user.

Abstract: Une cloueuse pneumatique à coup de maillet pour fixer un parquet en bois sur un faux-plancher, qui comprend un mécanisme de distribution de fixations comprenant à son tour un boîtier doté d'une chambre principale pressurisée placée en liaison directe avec une arrivée d'air comprimé, une chambre d'obturation dépressurisable sélectivement quand l'outil est au repos et un cylindre dans lequel un piston doté d'un plongeur fixé au piston est monté sur glissière. Une valve, inclinée en position fermée quand la chambre d'obturation est sous pression ou inclinée vers sa position limite ouverte si la chambre d'obturation est dépressurisée, permet la mise en place sélective d'une communication fluide entre l'intérieur du cylindre et la chambre principale pressurisée. Le piston, en position limite rétractée quand l'outil est au repos, est forcé vers une position limite déployée quand la communication fluide est établie entre la chambre principale et l'intérieur du cylindre, et afin que son plongeur frappe une fixation et l'enfonce dans une planche du faux-plancher. Utilisée une fois que le coup de maillet a induit la dépressurisation de la chambre d'obturation, la valve est déplacée jusqu'à sa position ouverte limite, une fixation sort de l'outil quand on frappe dessus par déploiement du piston frappé par son plongeur, et la chambre d'obturation commence à nouveau à être pressurisée par le liquide comprimé circulant à l'intérieur de la chambre principale par une première arrivée de liquide, qui déclenche le mouvement de la valve vers sa position fermée, et une fois ce mouvement déclenché, une seconde arrivée de liquide s'ouvre pour admettre une quantité supplémentaire d'air comprimé dans la chambre d'obturation et accélérer ainsi la pressurisation de la chambre d'obturation et le déplacement de la valve vers sa position fermée.
