Abstract: A laser transmitter projects a beam of laser light outward while raising and lowering the beam. The beam may define a conical surface of varying inclination. The transmitter includes a laser source that directs a beam generally vertically, and a beam diverting element. The beam diverting element is positioned in the path of the beam, intercepting the beam and redirecting it. The beam emerges from the transmitter as a non-vertical beam that is raised and lowered. The diverting element may include a pair of mirrors configured as a pentaprism, with one of the mirrors pivotable. Alternatively, the diverting element may include a plurality of micro mirrors. Also, the diverting element may include a conical reflector and an annular lens which is cyclically raised and lowered. The beam may be raised and lowered cyclically according to a predetermined schedule, or it may be raised and lowered non-cyclically.

Abstract: A method and system for delivering tailored asset information to a device are disclosed. According to one embodiment, a method accesses a database comprising information from a first reporting source about an asset and information from a second reporting source about the asset. A pre-defined user selectable criteria is then utilized to select portions of the information from the first reporting source and the information from the second reporting source. A tailored asset information report is then generated, wherein the tailored asset information report comprises the pre-defined portions of the information about the asset. In so doing, a layout of the tailored asset information report is provided based on a graphical user interface (GUI).

Abstract: A GPS information service system for providing supplemental GPS correction and signal acquisition information to subscribers. A GPS information server broadcasts GPS aiding information encrypted with subscription keys. A remote GPS subscription unit receives the key enablers for the subscription keys in service activation (SAM) messages for the services for which they have subscribed and then uses the subscription keys to decrypt the GPS aiding information. In order to prevent unauthorized access to the information, unsymmetrical signature generation and authentication algorithms are used for generating and authenticating signatures for the SAM messages.

Abstract: A combination laser detector and global navigation satellite antenna has a laser detector positioned in a known and fixed relationship with the nominal phase center of an included global navigation satellite antenna. The offsets for these elements may be fixed, simplifying set up.

Abstract: A system for selection by a user and delivery to the user over an internetwork transmission channel of selected audio data files at a delivery rate of at least twice the delivery rate for normal, audibly perceptible playback of an audio data file. The user registers the user's selection of audio material with a central library of audio and/or text data files, and a digitized and optionally compressed omnibus file containing the user's selections is prepared and transmitted to the user at a high data transfer rate. The user receives downloads the selected data files to a personal computer or to a portable storage and playback unit (SPU) that may store and play back digitized text or audio data, using a docking station. The user carries this SPU until the user has an opportunity to audio process and play back the text or audio data files in audibly perceptible form.

Abstract: A first communication device (e.g., the communication device that is sending data) monitors a radio channel in a predetermined set of radio channels. A message is transmitted on the first radio channel if the first radio channel is unoccupied. A second radio channel from the predetermined set of channels is checked if the first radio channel is occupied. The message is sent on the second radio channel if the second radio channel is unoccupied and the message was not sent on the first radio channel. In one embodiment, the transmission is sent in predetermined limited time blocks and predetermined set of channels is limited to a particular number of channels. In one embodiment a channel occupancy map and channel selection algorithm are utilized to establish the predetermined set of channels.

Abstract: Systems, methods, and devices for performing a trip management function are disclosed. A client computer accesses a server networked therewith to retrieve and store data, such as Web documents, relating to the trip. A wireless device interface allows a portable device, wirelessly coupled with a cellular telephone system with the network, to download the Web document. The portable device has cellular telephone functionality, geo-locating functionality, such as GPS capability, for determining its geo-location, and a processor for processing the Web document to help manage the trip. The Web document can include a set of map tiles, which encompass a particular geo-location area, and which form a dynamic map display. As the geo-location of the device changes, the next sequential map tile is downloaded and processed for displayed thereon.

Abstract: A combination laser system and global navigation satellite system has a laser detector positioned in a known and fixed relationship with the nominal phase center of an included global navigation satellite antenna. The outputs of the laser system and the global navigation satellite system are used together to determine position.

Abstract: An electro-optical total station system includes an EDM reference oscillator trained and disciplined by reference frequency standard information derived from local cellular telephone base station transmission carriers.
