Abstract: Directionally sensitive motion detectors at the entrances to elevator cars provide a running count of passenger population aboard the cars. Passengers wear portable devices that transmit personal IDs, and a check of IDs of passengers on the elevator along with the total passenger count will determine if each of the passengers exiting the elevator corresponds to an ID authorized to enter a particular floor of the building, or determine if each of the passengers aboard the car corresponds to an ID authorized to make a particular trip (the particular elevator at a particular time). Unauthorized exit may cause an alarm or other events. If any passenger does not have an ID authorized for a secure trip, an announcement urges the unauthorized passenger to leave for some period of time, following which an alarm is sounded and the elevator is prevented from moving. Pairs of motion detectors may provide directional sensitivity, or doppler motion detectors may be used.

Abstract: A wireless lockout apparatus, a system and a method for using the same are provided for receiving wireless signals from individual transmitters. When a first signal has a code that matches a reference code in a decoder, the decoder locks out subsequent signals and only allows the first transmitted signal to be routed through the processor. The processor determines which contestant sent the signal by interpreting the coded signal and indicates audibly and/or visually to which contestant the signal corresponded. A master transmitter has a bonus button and a reset button. The bonus button indicates a bonus question condition in a particular game. The reset button unlocks the decoder and allows the system to receive contestants' signals transmitted wirelessly.

Abstract: A system for providing protected two-way communication between a shared control database (“base station”) and at least one remotely located protector module/remote unit uses a two-way pager system in conjunction with a communications host and a security algorithm. The security algorithm has the capability of producing a time-varying password, say every sixty seconds, and can be made part of a microprocessor housed in the protector module. Each protector module has a unique inherently assigned identification number (ID) which is verified and authenticated by the control database each time a message is received from the remotely located associated protector module. In addition, the system makes sure that each communication between the control database and a remote unit has a component which matches a predetermined electronic identification number (EIN).

Abstract: A stealth system and method that allows a resource to be practically invulnerable to fast online brute-force attacks is disclosed. The method for controlling access to a computer resource consists in performing a user authentication procedure upon receiving a request from a user to access the computer resource.

Abstract: An emergency control system for opening or closing a gate resides within a controller for regulating operation of the opening/closing mechanism of the gate. A safety station is in communication with the controller and includes means to signal the emergency control circuit to open or close the gate by using either of two pushbutton switches. Sensing means which detect an unsafe condition in the area of the gate such as human entrapment is connected to the controller and initiates an alarm mode operation of the controller when an unsafe condition is detected and turns on a sound alarm. Pushing either of the safety button switches turns off the sound alarm and moves the gate. Movement of the gate is stopped if the pressed button is released while the gate is in motion which otherwise continues to its limit. The emergency control circuit is responsive to input signals from the safety station only when the controller is in the alarm mode.

Abstract: In an immobilizer controller, a key-side identifying information stored in a key is collated (compared) with an immobilizer-side identifying information stored in the immobilizer controller. In a shift controller, the key-side identifying information is collated with a shift-lock-side identifying information stored in the shift controller. If the identifying informations do not coincide with each other in at least one of the immobilizer controller and the shift controller, neither a fuel-injection-control permitting command nor a shift-lock-cancellation permitting command is output. An engine is maintained in its inoperative state, and a transmission is maintained in a state where rotation of a driving-torque transmitting shaft is prevented. If the identifying informations coincide with each other in the immobilizer controller, it is possible to reinforce security in comparison with the case where the fuel-injection-control permitting command and the shift-lock-cancellation permitting command are output.
