  • Patent number: 9059642
    Abstract: An integrated circuit for digital controlling switching noise spurs in a receiver by shifting a switching frequency (fs) to a clock frequency (fs+?f) to move a Kth harmonic of the switching frequency (fs) is provided. The integrated circuit includes a spur controlled clock that operates the clock frequency (fs+?f), and a DC-DC converter circuitry that includes a first power switch, and a second power switch. The first power switch and the second power switch are driven by the clock frequency (fs+?f). ?f ranges from ( f RF - Kf s ) + BW K ? ? to ? ? ( f RF - ( K - 1 ) ? f s ) - BW K - 1 , and fRF is center frequency of a received channel. None of the harmonics of the clock frequency (fs+?f) is present in a channel of interest. The switching frequency is larger than the channel bandwidth 2BW.

  • Patent number: 8791765
    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.

  • Patent number: 8265556
    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.
