Abstract: A system and method is provided for improving the operating range for UWB communication systems by increasing the margin between true correlation peaks and false correlation peaks in a received UWB signal. A received signal is first correlated with a UWB kernel before being correlated with the PRN code. The UWB kernel is a very short UWB pulse having the same pulse shape as the UWB signal pulses. By pre-correlating the received signal with the UWB kernel at least once prior to correlating with the PRN code, the margin between true correlation peaks and false correlation peaks is substantially improved.

Abstract: An apparatus comprises a radio frequency (RF) signal source; and a controller configured to adjust power of the RF signal source based on a detected parameter. In one embodiment, the apparatus further comprises a proximity sensor configured to determine proximity of the RF signal source to live tissue, and the detected parameter is the proximity determined by the proximity sensor. The RF signal source may be an RF antenna. The controller may be configured to reduce the power of the RF signal source when the proximity is less than a predetermined threshold value. The controller may be configured to reduce the power to a predetermined reduced power level.

Abstract: Embodiments of the invention provide for methods and apparatus for fragmenting a single message and sending the message fragments over multiple independent networks to a single receiving unit. The receiving unit then reassembles the message fragments to generate the original message. One embodiment of an apparatus according to the invention is a wireless radio frequency modem that can both receive and transmit fragmented messages over multiple independent networks.

Abstract: A communication routing arrangement includes two or more wireless routers coupled to a communication network, and a user device adapted to couple with the communication network through a communication path including at least one of the two or more wireless routers. The communication path between the user device and the communication network is selected based on available resources of the two or more wireless routers.

Abstract: A Universal Serial Bus (USB) modem/Wireless Wide Area Network (WWAN) device is provided that when connected to a host device, presents itself as an Ethernet endpoint to the host device, without requiring additional software/drivers to be downloaded to the host device. Embedded in the USB modem/WWAN device are various modules that provide functionality allowing either automatic connection to the Internet or redirection to a local Web User Interface (UI) that a user may employ to configure the USB modem/WWAN device and/or manually connect to the Internet. Additionally, the USB modem/WWAN device employs predetermined rules to determine whether or not/how the redirection occurs, including in scenarios where wireless connectivity to the Internet is unavailable.

Abstract: Methods, systems, devices and computer programs for configuring nodes on a wireless network can include generating a security key for the network, setting the security settings on the access point based on the security key, and saving the security key in a profile data file on a removable memory device along with a portable configuration utility for using the profile data file for configuring other nodes on the network. The removable memory device can then be inserted into other nodes and the portable configuration utility can be run to match the same key on the other network nodes based on the information stored in the profile data file on the removable memory device.

Abstract: A multi-mode modem comprises a first device configured to communicate with a first communication system, a second device configured to communicate with a second communication system, a processor communicatively coupled the first and second devices, and a control function configured to place the device in one of the following communication modes: 1) communication with the first communication system; 2) communication with the second communication system; 3) simultaneous communication with both the first and second communication systems; or 4) gateway communication between the first and second communication systems.

Abstract: A system and method for complete message delivery to a multi-mode communication device is presented. The communication device is adaptable to communicate with one or more carrier networks and one or more data networks. When a new message is received for the communication device, a message notification is sent to the device via a first network. The communication device parses the message notification and retrieves the complete message via a second network. Alternatively, the message notification may be delivered and the complete message may be retrieved via the same network.

Abstract: A system for enhancing location estimates by movable rovers including one or more base stations that engage in two way time transfer (TWTT) with the rovers. Each TWTT operation between a given base station and a given rover provides range measurements and clock differences between the base station and rover. The range measurements are based on the travel time of return TWTT signals and the clock differences are based on a phase offset of a code in the return TWTT signal and/or timing information included in the return TWTT signals.

Abstract: The invention relates to a method for correcting a distortion in an aerial photograph caused by a flight movement in the forward direction. The aerial photograph is captured by a surface sensor, the sensor lines of which sensor are exposed at different, successive exposure times, so that each individual sensor line senses a strip of terrain of the terrain flow over at the different exposure times. A relative flight altitude above the strips of terrain captured by the respective sensor line is assigned to the individual sensor lines. Furthermore, a compensation factor is separately determined for each of the individual sensor lines, wherein the factor depends on an air speed of the flying object, a focal length of the aerial camera and the relative flight altitude assigned to the respective sensor line, and corrects the distortion in the aerial photograph for the lines based on the respective compensation factor.

Abstract: A system and method for provisioning wireless devices such that they are only capable of accessing network services when in a specified location. A device surveys the current location of the device for existing base stations and stores a corresponding network environment profile. After the profile is stored, network services will only be provided to the device if the current network profile matches the stored profile.

Abstract: A system to determine position, frequency and clock offsets over a network utilizing signals of opportunity transmitted by one or more transmitters with known locations, the system includes a base receiver with a clock and a known position that determines ranges to the transmitters, takes a series of samples of the signals of opportunity and time tags the series with times of receipt, calculated times of transmission based on the calculated ranges, or both. The base receiver transmits the time tagged series and, as appropriate, computed ranges to the remote receivers. A given remote receiver saves and time tags samples of the signals of opportunity, correlates the time-tagged series with the saved samples, and calculates a time offset as a time difference of the times of receipt at the remote receiver and either the time of receipt at the base receiver or the time of transmission calculated at the base receiver.
