20110260749 | SYNCHRONOUS LOGIC SYSTEM SECURED AGAINST SIDE-CHANNEL ATTACK - An improvement in the security of a logic system from attacks that observable features such as the power supply or electromagnetic radiation, so called, “side-channel attacks”. Specifically, the present invention comprises a technique and method for reducing ability to monitor the relationship between currents in the system and the data in the system by closing the overall clock eye diagram, whilst keeping the eye diagram for connected stages open. The degree of eye closure for connected pipeline stages allows the system to run closer to its maximum operating speed compared to the use of system wide clock jitter, yet the overall closure provides security that is absent from systems with a partially open eye. | 10-27-2011 |
20110285420 | LOGIC SYSTEM WITH RESISTANCE TO SIDE-CHANNEL ATTACK BY EXHIBITING A CLOSED CLOCK-DATA EYE DIAGRAM - An improvement in the security of a logic system by minimising observable features such as the power supply or electromagnetic radiation, so called, “side-channel attacks”. Specifically, the present invention comprises a technique and methods for reducing the ability of an intruder to monitor the relationship between currents in the system and the data in the system through the use of a randomised clock wherein the clock eye diagram is closed and without significant reduction in maximum operating speed compared to the reduction in maximum operating frequency that occurs when using conventional means of additive jitter. A system where the clock eye diagram is completely closed is provably more secure than systems where the clock eye diagram is partially open. | 11-24-2011 |

20100077221 | System and Method for Wirelessly Transacting Access to a Set of Events and Associated Digital Content/Products - One or more content providers push data related to: movies, movie products, digital movie content over a network (e.g., a LAN, a WAN, the Internet, or a wireless network) onto an information filling station which, in turn, wirelessly transacts (over a network based on the 802.11b protocol) and transmits any requested data to a portable computer-based device (e.g., laptop, a pen-based computer device, a PDA, a wireless phone, or a pager). The portable device performs financial transactions for: purchasing movie tickets (directly or via auctions), downloading digital entertainment content of interest (e.g., copy of a movie of interest, copy of a movie identified based on a pre-stored profile, copy of soundtrack of a movie of interest), or movie related products. Any purchased digital content is either transferred wirelessly onto the portable device or, optionally, sent on a storage medium to a physical address associated with the profile. | 03-25-2010 |
20100092170 | Passive Optical Network and Ultrawide Band Adapter - A system includes a passive cable splitter and an ultra wideband adapter located at a customer premises. The passive cable splitter receives a video signal and a modulated ultra wideband data signal from a remotely-located ultra wideband adapter via a first cable.

The ultra wideband adapter located at the customer premises includes a combined signal interface to receive the video signal and the modulated ultra wideband data signal via a third cable. A demodulator extracts a data signal from the modulated ultra wideband data signal to generate a computer readable data signal. The computer readable data signal is output to a computing device via a data connection interface. | 04-15-2010 |

20150071466 | READ-OUT FOR MEMS CAPACITIVE TRANSDUCERS - Amplifier arrangements for read-out of MEMS capacitive transducers, such as low-noise amplifiers. An amplifier circuit has first and second MOS transistors, with the gate of the first transistor driven by the input signal, and the gate of the second transistor driven by a reference. The sources of the first and second transistors are connected via an impedance. Modulation circuitry is arranged to monitor a signal with a value that varies with the input signal and to modulate the back-bias voltage between the bulk and source terminals of the first and second transistors with the applied modulation being equal for each transistor and based on said monitored signal. The back-bias of the first transistor can be increase to extend the input range of the transistor in situations where the input signal may otherwise result in signal clipping, while avoiding noise and power issues for other input signal levels. By applying an equal modulation to the back-bias of each transistor, there is no substantial modulation of the output signal. | 03-12-2015 |
