Abstract:
An access control system is for at least first and second doors each having a lock adjustable between locked and unlocked states. A key has a code including first and second segments. A first controller coupled with the first door lock has a stored value and is configured to receive the key code and to compare at least the code first segment with the stored value, and unlocks the first lock when the code first segment corresponds with the stored value. A second controller coupled with the second door lock has a stored value and is configured to receive the key code and to compare at least the second code segment with the second stored value, and unlocks the second lock when either the code second segment corresponds with the second stored value or both code segments correspond with separate portions of the second value.
Abstract:
The invention relates to a method of operating an elevator system in a building with at least two storeys (1, 1', 1''), at least one elevator door (3, 3', 3'') and at least one building door (2, 2', 2''). Through opening and/or closing of a building door (2, 2', 2'') the storey (1, 1', 1'') of the opened and/or closed building door (2, 2', 2'') is defined as start storey and a destination call for an elevator cage (7) to the start storey is actuated: As soon as the elevator cage (7) has reached the start storey the elevator door (3, 3', 3'') of the start storey is opened. As soon as at least one user has entered the elevator cage (7) the opened elevator door (3, 3', 3'') is closed and the user is moved by the elevator cage (7) to a destination storey.
Abstract:
A card-reading device comprising at least one card-reading unit (60-75) and at least one display unit (80) for displaying information is characterised in that the at least one display unit (80) displays advertising information or similar when this action is initiated by the insertion or reading-in of a card.
Abstract:
Vorgeschlagen wird ein Handsender (10) zur fernsteuerbaren Auslösung eines technischen Ereignisses in einer von dem Handsender (10) beabstandeten zweiten Vorrichtung (300), insbesondere wobei das Ereignis eine Buchung, insbesondere Zutrittsbuchung und/oder Zeitbuchung, und/oder eine Türöffnung im Rahmen einer Zutrittskontrolle aufweist, wobei der Handsender (10) zur drahtlosen Kommunikation mit einer zweiten Vorrichtung (300) sowohl eine Nahfeldkommunikations-(NFC)-Schnittstelle (12) als auch eine Bluetooth-Schnittstelle (14) aufweist. Somit kann ein Handsender (10) (Transponder) realisiert werden, der, insbesondere als Bluetooth-Transponder, stets als aktiver Transponder zur Verfügung steht. Dabei kann der Transponder jedoch gleichzeitig, insbesondere wahlweise, herkömmliche passive Ausweise ersetzen, nämlich insbesondere als NFC-Transponder, bevorzugt als aktiver NFC-Transponder.
Abstract:
The interface is used for transferring data between receiver terminals at central control units on computer etc., pref. within a telephone extension network and factory terminal units. The system provides exchange of data at a very high data transmission rate e.g. by the current-loop process, and yet avoids the high noise level associated with this transmission method, making possible the use of standard equipment. In the process, each square-wave output pulse corresp. to a data bit and derived from the primary transmission network is converted into a stair-case sinewave, and the sequential waveforms, after smoothing are taken via a transmission line to a receiver-transducer stage, wherein reconversion into the square-wave sequence takes place. The recovered square waveform is then supplied to the receiver of the primary transmission network.
Abstract:
The optical reader is for use with a card carrying 2 tracks of transparent markings at least one of which provides clock signals either as a clock track or as a self-clocking data track. Temporary reversal of movement of a card, e.g. when being manually inserted, may be detected in the usual way using spaced sensors for the clock track. On insertion of a card a switch-over from low power standby pulses to high power pulses at a level above their normally acceptable by the light sources under continuous operation may be made.
Abstract:
Allocated to a person/object (13), a mobile component (15) contains a mobile transmitter for making high-frequency (HF) signals (E1) available that are beamed from a mobile antenna and picked up by a stationary receiver (SR) (18). A signal-rating device (20) captures an HF parameter for an HF signal (E1a) picked up by the SR and detects people/objects by using the captured HF parameter.
Abstract:
A system is proposed for transmission and back transmission of data, preferably within closed line networks, in which a transmitter and a number of receivers (terminals) are in each case provided which are connected to the transmitter in a closed current loop. For data transmission, the transmitter generates a pulsed constant current and, for voltage limitation and stabilisation, makes use of a control circuit in the form of a sample-and-hold circuit which draws surplus constant current from the line when the closed line loop is interrupted by one or more of the connected terminals. An undesirable, excessively high voltage rise is thereby prevented and automatic line balancing is achieved independently of prevailing conditions on the line.
