    Abstract: A proxy is utilized to limit the RF bandwidth needed for foreign IP registration. An existing RF login procedure causes the proxy to initiate and complete the foreign IP registration procedure with the foreign agent at the RF site where the mobile node is located. The proxy then acts as a locally connected (i.e., direct ethernet connected) device for each IP address for which it is proxying, and thus there is no need to use RF to register a mobile with the active foreign agent. This allows the use of off-the-shelf home and foreign agents to complete the mobile IP architecture, and reduces the RF bandwidth used, since the RF portion of the registration process (the registration between the active foreign agent and the mobile) is reduced.

    Abstract: A microphone unit comprising a voice input for receiving (22) a voice input signal, an analog to digital converter for creating (26) a digital signal from voice signal, a voice coding device for creating (28) a voice coded signal output from the digital signal, encryption means for encrypting (30) the voice coded signal, and a modulator for generating (32) a transmittable signal that can be supplied (34) to a radio via the microphone input. Additionally, the microphone unit is capable of performing the steps in reverse upon receiving an encrypted signal. The received signal output from the radio is demodulated, un-encrypted, voice decoded, converted from a digital voice signal to an analog voice signal, and output via a speaker which is preferably built into the microphone unit.

    Abstract: The invention is directed to a system for determining a transfer function for emphasizing an electromagnetic signal prior to being processed by determining a discrete transfer function for a processing system, such as a wideband phase modulator; determining a target transfer function such that the target transfer function multiplied by the inverse of the discrete transfer function produces a discrete pre-emphasis transfer function; and transforming any unstable poles and/or zeros in the pre-emphasis transfer function to stable poles and/or zeros. The discrete transfer function may be determined, for example, by using an S-function, input and output signals, the inverse-invariant method, and/or the Steiglitz-McBride algorithm. The transformation of the unstable poles and/or zeros may be accomplished using an all pass filter. The target transfer function may be a low pass FIR filter having a gain of about unity across substantially all of the frequency range of said FIR filter.

    Abstract: A heterojunction P-I-N diode (300) switch comprises a first (20) layer of doped semiconductor material of a first doping type, a second layer (40) of doped semiconductor material of a second doping type and a substrate(50) on which is disposed the first and second layers (20, 40). An intrinsic layer (30) of semiconductor material is disposed between the first layer (20) and second layer (40). The semiconductor material composition of at least one of the first layer (20) and second layer (40) is sufficiently different from that of the intrinsic layer (30) so as to form a heterojunction therebetween, creating an energy barrier in which injected carriers from the junction are confined by the barrier, effectively reducing the series resistance within the I region of the P-I-N diode and the insertion loss relative to that of homojunction P-I-N diodes.

    Abstract: A method for measuring the range and bearing of an object. At least a portion of a first signal is transmitted from a sensor. The transmitted signal is reflected from an object and received by the sensor. At least a portion of the first signal is applied to a first mixer (418) and a second mixer (420). The received signal is also applied to the first mixer (418) and the second mixer (420). A second signal is generated from the first mixer, and a third signal is generated from the second mixer when the portion of the first signal that was transmitted overlaps the reflected signal at least partially. Bearing angle, degree on or off boresight and object range may be determined from the second and third signals, or a combination thereof. Also disclosed is a sensor for object range and bearing measurement.
