摘要:
A system includes a system bus having data lines, an acknowledge line, an enable line, and a control line, a data storage device, a controller circuit, and an arrangement coupling the system bus, controller circuit and data storage device. The system bus can carry out a data transfer cycle in which the acknowledge, enable and control lines are actuated and the controller obtains and checks data from the data storage device and supplies it to data lines of the bus, and a verify cycle in which the acknowledge and enable lines are actuated and the control line is deactuated and the controller obtains and checks data from the storage device but does not supply it to the bus. The controller circuit is capable of operating in different modes, in one of which it forcibly sets a false error indication in response to the verify cycle. In response to the acknowledge line and enable line being simultaneously actuated while the control line remains deactuated throughout a cycle, an arrangement supplies a special signal to the controller circuit so that the controller circuit interprets the cycle as a data transfer cycle and does not set a false error indication.

A computer system includes a control circuit having a request input, and a pair of connectors which are electrically coupled to the control circuit and are each connected to the request input of the control circuit, each connector being capable of removably receiving a circuit card. The control circuit includes a checking arrangement for detecting a condition in which the connectors each have therein a card having a request output controlling the request input of the control circuit.

A memory system includes a memory unit with plural addressable storage locations, a connector arrangement for detachably electrically coupling the memory unit to a computer, and a decoding arrangement for determining whether a computer memory address is within a range of addresses to which the memory unit is to respond, the decoding arrangement including a base address register storing a value representing the first address in the range and a size register defining the number of addresses in the range. A method by which a computer can automatically configure this system includes the steps of determining a base address to be associated with the connector, loading into the base address register a value representing the base address, loading into the size register a value representing the maximum range of addresses, thereafter selectively accessing storage locations to determine the actual number of contiguous locations in the memory unit, and then changing the size register, when the actual number of locations is less than the maximum range of addresses, to a value representing the actual number of locations.

Methods and systems for modifying a carrier frequency for a trainable transmitter may include receiving a request to transmit a control signal from the trainable transmitter to a receiver. A transmission of a first control signal may be made using a trained carrier frequency and a control data. At least part of the carrier frequency may be shifted by a frequency increment. A second control signal may then be generated using the carrier frequency shifted by the frequency increment and the control data. The second control signal may then be transmitted.

The present application relates to an in-vehicle control system for synchronizing files with a remote source. The remote source includes a storage device configured to store a first file. The system includes a communications device capable of establishing a wireless communication link with the remote source. The communications device is configured to send, receive, or both send and receive files to and/or from the remote source. The system further includes a memory device configured to store a second file. The system yet further includes a data processing device coupled to the communications device, the data processing device configured to perform a comparison of the first file of the remote source and the second file of the memory device, wherein the data processing device is further configured to synchronize the file of the remote source and the file of the in-vehicle control system based on the comparison.
摘要:
A wireless control system is configured to be trainable to control any number of remotely controlled devices. The system can be configured to gather and learn information relating to a signal transmitted by the original transmitter in a manner that is blind to a user of the system. The system can be designed to learn signals automatically such that fewer steps are necessary for a user to train the system to control a particular remotely controlled device. The system can train to remotely controlled devices in this manner with little or no user action required.

A method for training a trainable transmitter in a vehicle includes receiving a request to enter a training mode of the trainable transmitter from a user. In response to the request, default mode data is retrieved from a memory and transmitted for a predetermined time. Upon expiration of the predetermined time, the trainable transmitter begins a training mode.
