摘要:
A method and system for providing information to an individual using an electronic sign in which the sign displays information in response to the identity of the tag or an account associated with the tag. The information is displayed when the tag, which may be carried by the individual or in a vehicle, approaches the sign. A user can preselect from among various information types he wishes to receive, such as news, weather, sports and personal messages. The user can also select a priority for each information type.
摘要:
A method and system for alerting a driver of a commercial vehicle or private vehicle, such as a truck or automobile, of an approaching emergency vehicle, such as a police or fire vehicle, and vice versa. The system includes a navigation information system in each vehicle, a transmitter in the second vehicle, a receiver in the first vehicle, a processing system, and a warning system in the first vehicle. Each navigation information system provides data that describe the geographic position and speed of the vehicle. The receiver in the first vehicle receives the navigation information transmitted by the second vehicle. The processor and associated electronics in the first vehicle determines the position and direction of travel of the second vehicle relative to the first vehicle. The warning system in the first vehicle provides a suitable indication to alert the driver if it is determined that the two vehicles are likely to collide.
摘要:
Method and apparatus for controlling data communications in response to environmental cues. The transmission and/or reception of data by a computer disposed onboard a vehicle may be controlled to avoid loss of data, unintentional transmission of data, etc., where predetermined environmental conditions are detected. In one embodiment, information is buffered when a predetermined condition is satisfied. The predetermined condition may include, for example, deceleration/acceleration, loss of traction, impact to the vehicle, impaired visibility conditions, loss of air pressure in a tire, engine stall and the like.

A disk and spindle motor assembly of a rotating disk drive is constrained from freely rotating when not in use to reduce fretting of the spindle assembly bearings in the presence of vibration. Preferably, a small electric current is driven through at least one of the spindle motor drive coils to hold the spindle assembly in a fixed angular position while the disk drive is not in use. The spindle motor is preferably a brushless DC motor comprising a multi-phase electrically driven stator and a permanent magnet rotor. Drive transistors normally drive the different phases under control of a processor. To constrain the drive, at least one of the drive transistors for a phase is activated. The rotor is preferably rotated periodically to a different angular position by driving a different phase of the stator. The rotor is alternatively constrained by mechanical means. The exemplary environment is an on-board motor vehicle application.

As a mobile unit approaches a communication dead zone, a call is automatically disconnected in an orderly fashion. The call can be automatically reconnected when the mobile unit exits the communication dead zone. As part of the orderly disconnection, parties to the call are given an audible and/or visual message and/or sensual tactile stimulus letting them know that a dead zone is being approached. The message can also indicate the time before entering the dead zone, and/or what actions will be taken. Similarly, when the mobile unit is about to exit the dead zone, the parties can be given an indication prior to being reconnected.
摘要:
A system for cooling an electronic device containing a heat-generating component, comprises a surface thermally coupled to the heat-generating component to be heated by the component. A fabric material is positioned proximate the surface, and includes a plurality of fibers having heat conductive properties. The fabric material is configured for engaging the heated surface such that the heat conductive fibers of the fabric material are operable for conducting heat away from the surface to cool the component and the electronic device.
摘要:
A method for providing control accesses between a device on a non-proprietary bus and a device on a proprietary bus is disclosed. A gateway controller is connected between a proprietary bus and a non-proprietary bus. A message originated from a device on the non-proprietary bus intended for a device on the proprietary bus is checked by the gateway controller to determine if a transmission of the message should be permitted according to a permitted message bitmap. The permitted message bitmap contains a list of devices on the non-proprietary bus that are previously registered as able to communicate with devices on the proprietary bus and a list of permitted messages associated with each of the devices on the non-proprietary bus. The transmission of the message to the device on the proprietary bus is denied if the message is not registered within the permitted message bitmap.

摘要:
A method for verifying control accesses between a device on a non-proprietary bus and a device on a proprietary bus is disclosed. A gateway controller is connected between a proprietary bus and a non-proprietary bus. A determination is made as to whether or not a non-proprietary device is registered to more than one gateway controller. In response to a determination that the non-proprietary device is registered to more than one gateway controller, another determination is made as to whether or not the non-proprietary device is a portable device. In response to a determination that the non-proprietary device is a portable device, another determination is made as to whether or not a number of acceptable duplication has been exceeded. In response to a determination that the number of acceptable duplication has been exceeded, a flag is set to indicate a control access violation has occurred.

A method for producing a response to driving conditions ahead of a land vehicle such as an automobile includes a second vehicle using information received from a first vehicle traveling ahead of it to adjust vehicle mechanisms such as the suspension to cancel adverse effects of road anomalies sensed by the first vehicle.
