Abstract: A modifiable transmitter is used with an operator to control a position of a barrier. The operator includes a controller for comparing radio frequency transmissions received with stored serial numbers so that the controller can move the barrier when a radio frequency transmission matches any one of the stored serial numbers. The transmitter includes a housing that carries an encoder. A function button is carried by the housing, wherein actuation of the button generates in a first non-standard way a new serial number that can be learned by the controller to allow the modifiable transmitter to move the barrier by emitting the radio frequency transmission. A second non-standard way, which can only be implemented after use of the first non-standard way, may also be used to generate a new serial number. A restricted access button may also be activated to generate a new serial number.

Abstract: A programmable remote control automatically learns characteristics necessary to generate an appliance activation signal. A sensor is positioned proximate to the appliance. A sequence of different activation signals is transmitted. A determination as to which signal activated the appliance is made based on a received sensor signal. Data representing the determined activation scheme is associated with an activation input.

Abstract: Provided is a remote control system capable of preventing a key code from being deciphered when the key code is transmitted from a transmitter to a receiver to be registered. In the transmitter, in response to a specified switch operation, a k-th common key code in a table to be used for enciphering a key code is changed to a registration key code stored in advance so that a key code is enciphered through the use of the table including the registration key code. A transmission code is produced by adding a predetermined code to the enciphered key code and the transmission code signal is transmitted to the receiver. This prevents easy deciphering of the key code because the key code is transmitted in a state enciphered.

Abstract: In a method for securing an object against unauthorized use, an interrogation unit (1) transmits an interrogation signal (s) and tests whether a response unit (2), which is to be carried by an authorized user, responds to the interrogation signal with a response signal (r) that contains as information a code authorized for desecuring a security device (3). If so, the security device is desecured. The securing method shall prevent unauthorized persons from establishing a radio link via relay stations between the interrogation unit (1) and the response unit (2) for providing the authorized code via this radio link without being noticed by the authorized user. The securing method prevents the desecuring of the security device (3) if the signal transit time of a signal transmitted as the interrogation signal (s) and received as the response signal (r) by the interrogation unit (1) during a monitoring time interval (t4–t5) is greater than a prescribed value.

Abstract: Methods and apparatus are provided for insuring that a motor vehicle is being operated by an authorized operator. The apparatus includes an electronic control unit (ECU), an engine immobilizer unit, and a shared encryption key. The ECU generates a challenge by combining the output of a pseudo-random number generator and the output of a somewhat random number generator and cycling the combined number through a linear feedback shift register. The ECU sends the challenge to the immobilizer unit where it is encrypted with the shared key and sent back to the ECU as a response. The ECU uses the same key to encrypt the challenge and compares the encrypted challenge to the response. If the response matches the encrypted challenge, engine operation is enabled.

Abstract: A transmitter has a dummy load circuit. The dummy load circuit is driven prior to writing of a rolling code into a memory. It consumes the amount of power corresponding to the amount of power consumed during the writing of the rolling code. The dummy load circuit monitors the condition of decrease in the source voltage of a battery. If the source voltage becomes lower than a predetermined reset voltage, the dummy load circuit resets the transmission data generation controller. With this operation, a wrong rolling code is not written into the memory.

Abstract: An improved electronic lock system is provided for use with real estate lock boxes where there is the need for many people to access the secured compartment of the lock box in a controlled manner. Each user has an identification card with a non-volatile secure memory (known as a “smart card”), for exchanging data with the lock box, and with a portable computer capable of reading data from the smart card; or a cell phone can be used to gain access information from a central computer. The user first inserts the smart card into the connector attached to the lock box; the lock box reads the user's ID stored in the smart card memory and records this information in lock box memory. The lock box then transfers its access code information and other data to the smart card for further processing. The user then inserts the smart card in a portable card reader to learn the access code, or calls a central computer via a mobile phone system and interacts with the computer to elicit the necessary access code information.

Abstract: Secure Home Delivery SystemA system for providing secure delivery or collection of goods too large to be delivered through traditional apertures such as the letterbox, to a location, such as a home, where the goods have previously been remotely ordered using remote means such as the internet or telephone. Access to a secure location, for example, a dedicated receptacle, garage or shed, is achieved by presentation of an access code by the delivery personnel, the origin of which is linked to the order of the goods. The access code may be computed using time-based algorithms that are replicated by the lock at the delivery location, unlocking occurring when the access codes coincide. The lock can provide access to a key safe, which in turns holds keys to a secure location. The system could equally be used for the collection of goods and for providing access to utility meters.

Abstract: A secure system using a continuously-changing key that depends on the user's body part. A preferred embodiment obtains an image of the user's fingerprint and cements it according to a random generator. Only part of the image and not all of the image is sent at one time. The random segmentation insures that part of the image that is sent continuously varies from time to time. Therefore, an unauthorized receiver can receive only part but not all of the image. That only part of the image which is received will usually not be the same at the second as it is at the first time. Therefore, a received code cannot later be used to fool the system with the same credit card.

Abstract: A combination lock is described where the combination that is used to open the lock is generated on a separate computer system using information that is contained in the lock and a series of steps that combine selected items of the information contained in the lock and alter the results of the results of the combination of the information items. The lock incorporates a computer processor which performs the identical steps to generate an authorized combination after a combination is entered into the lock. When the two combinations match, the lock is enabled for opening. At least some of the information items used in the generation of the combinations change with each successful opening of the lock, rendering the combination generated by the computer system useable for only a single opening of the lock.
