Abstract: A silicon-based optical modulator exhibiting improved modulation efficiency and control of “chirp” (i.e., time-varying optical phase) is provided by separately biasing a selected, first region of the modulating device (e.g., the polysilicon region, defined as the common node). In particular, the common node is biased to shift the voltage swing of the silicon-based optical modulator into its accumulation region, which exhibits a larger change in phase as a function of applied voltage (larger OMA) and improved extinction ratio. The response in the accumulation region is also relatively linear, allowing for the chirp to be more easily controlled. The electrical modulation input signal (and its inverse) are applied as separate inputs to the second region (e.g., the SOI region) of each arm of the modulator.

Abstract: A shopping cart conveyor that inhibits the loading of a non-compliant shopping cart onto the conveyor. In one aspect, the invention provides a conveyor comprising a track operable to guide the shopping cart between a first location and a second location, a gate assembly including a door movable between a closed position inhibiting entry to the track and an open position allowing entry to the track, a lock for securing the door in the closed position, and a sensor (e.g., an ultrasonic sensor, an optical sensor, a radar sensor, an infrared sensor, an RFID reader, a magnetic sensor, and a mechanical sensor) positioned to detect the presence of a shopping cart. In another aspect, the conveyor is configured to move the gate from the closed position to the open position when the sensor detects the presence of a shopping cart. Preferably this is done using a drive mechanism coupled to the gate.

Abstract: Thrombectomy catheters are presented that have curved tip portions. A suction lumen extends from at or near the proximal end of the catheter to a suction port at or near the tip portion of the catheter. The curves of the thrombectomy catheter can be selected to place a suction port at or near a vessel wall for the more effective removal of thrombus resulting from directing the suction in the direction of the thrombus. In some embodiments, the tip portion of the catheter can be transitioned from a first configuration for delivery of the catheter into the vessel to a second more curved configuration with a desired design for application of suction. The catheter can be moved in a circumferential and/or lateral direction to cover selected portions of the inner vessel wall. In some embodiments, a partially occlusive structure can be used to reduce and/or redirect flow within the vessel to improve performance of the thrombectomy.

Abstract: Disclosed is a method of fabricating an optical waveguide device including the steps of forming a mask over a waveguide core material layer so as to leave a portion of the layer exposed, and exposing the structure to an oxidizing environment to form an oxide layer on the waveguide core material layer at least in the exposed portion thereby defining the lateral dimension of the waveguide core. The resulting waveguide core has extremely smooth surfaces for low optical losses.

Abstract: A 10 MHz channelized orthogonal frequency division multiplexing (OFDM) transmitter is provided that communicates using a modified OFDM packet structure with a half-rate oscillator having standard accuracy. The transmitter has an inverse fast fourier transform (IFFT) data processor that appends an outer pair of data subcarriers on either end of an OFDM subcarrier profile. An IFFT long sync processor appends an outer pair of binary phase shift key (BPSK) subcarriers on either end of an OFDM long sync subcarrier profile. By copying or appending the information of the data subcarriers closest to zero Hz. to more robust locations, 10 MHz channelized OFDM can be achieved with half-rate clocks and 20 PPM oscillators.

Abstract: An on-signal calibration system I and Q signals of a transmitter to remove distortions in the RF output signal. The transmitter generates I and Q values and converts, modulates and combines the I and Q values into the RF output signal for transmission. The calibration system includes a detector, a sampler, a selector, an imbalance estimator, and an IQ corrector. The detector senses the RF output signal and provides a detection signal indicative thereof. The sampler samples the detection signal and provides digital samples. The selector selects from among the digital samples that correspond to predetermined ranges of the I and Q values, or otherwise predetermined selection boxes at predetermined phases. The imbalance estimator determines at least one imbalance estimate based on selected digital samples. The IQ corrector corrects the I and Q values using at least one imbalance estimate.
