20090002213 - Method and apparatus for a high bandwidth oscilloscope utilizing multiple channel digital bandwidth interleaving: A method of digitizing an analog signal is provided, comprising the steps of separating the analog signal spanning a frequency range into a plurality of frequency bands, each frequency band spanning a corresponding predefined frequency range, at least a portion of each of the plurality of corresponding frequency ranges not... Agent: Lecroy Corporation

20090002214 - Filter with forward coupling: This disclosure relates to techniques and architecture for summing, sampling, and converting signals associated with a capacitive feedforward filter using a quantizer.... Agent: Lee & Hayes, PLLC

20090002215 - Sample and hold circuit for a current mode pipelined analog-to-digital converter: A pipelined current mode analog-to-digital converter, including: a plurality of stages each having a first sample and hold circuit configured to receive an analog signal having a current; the sample and hold circuit having at least first and second outputs; the first output having a current from a current copier... Agent: Steven L. Nichols Rader, Fishman & Grauer PLLC

20090002216 - Method and device for processing an incident signal, in particular for filtering and analogue/digital conversion: The method and device include the filtering and the analog/digital conversion of an intermediate signal. The intermediate signal is processed by a filtering and analog/digital conversion circuit that is configurable using switched passive capacitor technology. The various configurations successively adopted by the circuit provide filtering and analog/digital conversion to be... Agent: Allen, Dyer, Doppelt, Milbrath & Gilchrist P.A.

20090002218 - Direction and holding-style invariant, symmetric design, touch and button based remote user interaction device: A remote control unit selectively transmits a control signal for remotely controlling an electronic device. The unit defines an imaginary cut plane that substantially bisects the unit. The unit includes a plurality of input features collectively disposed symmetrically with respect to the imaginary cut plane. The input features include a... Agent: Gregory A. Stobbs

20090002217 - Touchpad-enabled remote controller and user interaction methods: The handheld case of the remote control unit includes at least one touchpad, and other sensors, such as acceleration sensors, case perimeter sensors, pressure sensors, RF signal sensors. These sensors provide a rich array of sensory inputs that are classified by a pattern recognizer to generate control commands for both... Agent: Harness, Dickey & Pierce, P.L.C

20090002219 - Two way communication between an appliance and a remote control: A method for storing and using information received from a controllable appliance in a controlling device. In response to a detected activation of a key of the controlling device the controlling device transmits a request signal to the controlled appliance for the purpose of retrieving from the controlled appliance data...
