Abstract: A display system comprising a steerable display having a monocular field of view of at least 1 degree, positioned within a scannable field of view of at least 20 degrees, the steerable display positioned for a user. In one embodiment, the steerable display is positioned for the user's fovea.

Abstract: A SCUBA diving flag/float assembly is used to support a GPS antenna on the surface of the water for use by divers in performing underwater navigation. An associated GPS receiver is integrated with a dive flag line take-up mechanism such as a spool or SCUBA diving line reel. The dive flag line and cable interconnecting the GPS receiver to the GPS antenna is integrated within a single assembly, or in an alternate embodiment, braided together forming a single tether. Alternate embodiments include optional sensors such as a flowmeter, compass, tiltmeter, depth gauge and diver techniques to compensate for navigational errors due to a water current pushing a dive flag/float away from a diver. Alternatively, a GPS receiver may be mounted on or in the dive flag/float assembly and navigational information relayed to the diver under the water.

Abstract: A blind spot detection system includes a transmitter directing a circularly polarized signal into a blind spot adjacent a vehicle. A receiver also mounted on the vehicle receives a reflection of the circularly polarized signal which is oppositely circularly polarized. An indicator indicates to the driver of the vehicle when the reflected signal is detected, thereby indicating the presence of an object in the blind spot. An indicator is also directed toward the blind spot generating a warning when the presence of an object in the blind spot is detected and an indication of a turn or lane change by the vehicle is detected, such as turn signal switch activation.

Abstract: A trainable transmitter comprises a transmitter, code-generation circuitry and a removable, plug-in data module. The data module includes information necessary for generating a code for a specific security system, such as a garage door opener. Preferably, the data includes a cryptographic algorithm and the frequency at which the wireless signal is to be generated. The code-generation circuitry accesses the data in the data module to generate a code, which is then transmitted by the transmitter. A variety of data modules are provided. A user installs a data module which corresponds to the security system to be accessed.

Abstract: A safety warning system includes a safety warning transceiver which retransmits safety warning signals received by the safety warning transmitter in order to extend the range of safety warning transmitter systems. The safety warning transceiver also functions as a trainable garage door opener and interacts with the remote keyless entry system of the vehicle. In one embodiment, the safety warning transceiver can be installed and selectively removed from a docking station in the vehicle in order to prevent theft or install the safety warning transceiver into another vehicle.

Abstract: A passive remote keyless entry system includes a plurality of sensors each associated with a door of the vehicle. Each sensor detects the presence and distance of a key fob from the sensor. By monitoring the distance of the key fob from the sensor, the sensor determines if the key fob is approaching or moving away from the associated door. If the sensor determines that the key fob is approaching, an interrogation signal is sent from the security system to the key fob. If the proper code is returned by the key fob, the associated door is unlocked. If the sensor determines that the key fob is moving away from the associated door, the doors are locked. The sensors can also determine whether the key fob is simply passing by, in which case the driver probably does not wish to enter the vehicle.

Abstract: A wireless compass for vehicles includes a compass sensor installed in a first location of a vehicle. The compass sensor sends information regarding the heading of the vehicle via a wireless transmitter. A compass display includes a complementary wireless receiver which receives the data from the compass sensor. The compass display and receiver are located at a second location convenient for the driver. The display displays the heading of the vehicle based upon the data received from the compass sensor.

Abstract: A garage door opener transmitter system includes a sensor for determining the relative direction of the garage door opener receiver. A transmitter then selectively transmits a signal in the direction of the receiver. In one embodiment, the direction of the receiver is determined based upon a compass and the direction of travel of the vehicle at the time the signal is transmitted.
