Abstract: A method for calibrating a radio transceiver begins by injecting a low-frequency tone at a transmit power amplifier input of the radio transceiver, where the low frequency tone is at least an order of magnitude lower than the operating frequency of a local oscillator coupled to the transmitter input. The method continues by upconverting the low-frequency tone to produce a plurality of tones at a transmit power amplifier output and then determining which tone of the plurality of tones is a local oscillator feedthrough tone associated with a transmit power amplifier output and which tone of the plurality of tones is representative of an in-phase and quadrature (I/Q) imbalance associated with the transmit power amplifier output.

Abstract: A glass unit for an illuminated vehicle roof has a glass pane, a plastic film and an outer and an inner polyurethane layer. These components are stacked one on top of the other in a planar manner in the following order: glass pane, inner polyurethane layer, plastic film, outer polyurethane layer. Furthermore, the plastic film has a lower refractive index than the adjacent outer polyurethane layer.

Abstract: Techniques are described for peak-adaptive sampling demodulation for radiofrequency transceivers. For example, a tag input signal is received via an antenna, from which a clock input signal can be extracted. Multiple clock output signals can be generated responsive to the extracted clock input signal, such that each has a different respective phase. A multiphase selector can identify the one of the clock output signals that has the respective phase that is closest to the phase of the tag input signal and is best suited for sampling the peak of the tag input signal, accordingly. A single-path detector can generate a data output signal by using the identified clock output signal to sample the tag input signal, and the detector can filter and amplify the data output signal using small-signal devices.

Abstract: A Force-Mode Distributed Wave Oscillator (FMDWO) that provides accurate multiple phases of an oscillation, a Force Mode Distributed Wave Antenna as a radiating element, a Force-Mode Distributed Oscillator Amplifier (FMDOA) and an array of amplifiers capable of operating as a beam forming phased-array antenna driver. Two distinct force mode mechanisms, one delay-based and the other geometry-based, utilizing inverter amplifiers, inject an oscillation on independent conductor loops or rings via transmission lines forming a differential transmission medium for the oscillation wave. Once the oscillation wave is initiated through the forcing mechanisms, the oscillations continue uninterrupted independent of any external triggering.

Abstract: Integrated mobile phone and medical implant system. The disclosed system integrates the available electronic resources that already exist in compact and portable devices, such as any generic mobile phone, with a body implantable medical device such that the sensory data obtained from the implant device is transmitted through an electronic umbilical cord directly to the mobile device where the data is analyzed and presented in a user-friendly manner to the user/patient and/or transmitted wirelessly to a remote location for further action, if necessary, without the need for additional equipment. With the switch of software application from a drop-down menu, the mobile device of the system functions both as a normal mobile phone, as a medical monitoring device, or both simultaneously without any interference between the two modes of operations. Method for using the integrated system is also disclosed.
