Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

Abstract: A method for selecting an air interface on a multi-mode wireless device capable of communicating over a plurality of air interfaces. The method comprising starting a first application and selecting a first application specific access list of a set of application specific access lists, the first application specific access list corresponding to the first application. The method also comprising selecting a first active network from the first application access specific list, the first network representing an available and most desirable network for the first application in the first application specific access list. The method further activating the first active network for use by the first application and switching from the first active network to a second active network if a user switches from the first application to a second application, wherein the first active network and the second active network are ascertained based on the set of application specific access lists.

Abstract: A wireless communications device and network having the ability to detect when a call session with a public service access point (PSAP) has not transferred location information for the wireless device to the PSAP. In on embodiment, the detection means includes a location request timer (LRT), which is started when the emergency call is initiated. If the LRT expires before a request for location information is received by the wireless communications device, the wireless device concludes that the PSAP does not have the location information. In another embodiment the wireless network determines the PSAP does not have location information without a timer. The location information is then presented to a caller on the wireless device, which allows the caller of the wireless device to relay the information to a human PSAP operator. The location information may also be provided to a human PSAP operator in a automated manner.

Abstract: A wireless communications device having a localized preferred roaming list (WLANL), the WLANL having location specific WLAN AP information associated with it. A mobile wireless device uses the information in the WLANL to manage active searches for WLAN APs. In addition, the WLANL information can be used to mange active sessions, enabling a switch from one air interface to another depending on which air interface is currently the most reliable, has bandwidth available, or other considerations.

Abstract: A system and method are presented for minimizing loss of voice packet during a wireless communications device Candidate Frequency Search (CFS). The method includes monitoring frames in a predetermined sample frame sequence and identifying frames having minimal user information. That is, frames with lower frame rates. The method further includes, in a wireless communications device, performing a CFS responsive to identifying frames having minimal user information. One example of the method includes identifying a lowest frame rate in an initial frame and performing a CFS in a frame following the initial frame. The method includes monitoring forward direction link frames and reverse direction link frames, and simultaneously monitoring forward and reverse direction link frames.

Abstract: Briefly, the location capable mobile handset allows the user to provide a call recipient with the location of an unsuccessful attempted emergency call. In one specific example, the call may be an E911 call to a PSAP dispatcher, however, it will be appreciated that the call may be to request assistance from a family member, or friend. Additionally, the call may be to a towing service. The call could be any call that a mobile handset user wants to send location information to the party that has been called. Returning to the E911 call example, the location information reported to dispatcher can include the location of initial E911 call, current location during a successful E911 call, or ground track information from the initial location to the current location. When an E911 call is unsuccessfully attempted the mobile handset stores the location of the mobile handset at that time. This information can later be transmitted when the mobile handset is in a coverage area.

Abstract: The substrate for implementation of MMIC devices comprises alumina with feedthrough holes drilled therein to provide conduct ion paths from the top surface of the substrate to the bottom surface. A high-temperature to low-temperature fabrication process is used to form circuit traces and components upon the substrate. Each of the thick film deposition processes is followed by a firing process to remove organic materials from the deposited material and to secure the material to the substrate or previous layer. A Ku-band transceiver constructed using the process includes the attachment of six discrete, unpackaged MMIC's and one HEMT. All other devices and traces are patterned on the substrate and the discrete components are directly attached to pads on the substrate.

Abstract: In a radar system, an RF signal is transmitted at a frequency modulated by a sawtooth signal. The transmitted RF signal is mixed with the transmitted signal reflected from an object. The resulting IF signal is analyzed into a Fourier series having a DC coefficient and harmonic frequency coefficients. The range to the object is determined from the harmonic frequency coefficients in multiples of the range resolution determined by the RF bandwidth of the system when the DC coefficient is less than each of the harmonic frequency coefficients. The range to the object is determined to be within 1/2 the range resolution determined by the RF bandwidth when the DC coefficient is greater than each of the harmonic frequency coefficients.
