20100127734 | Out-Of-Band Signaling Using Detector with Equalizer, Multiplier and Comparator - Power-down mode is activated when equal voltages are detected on a pair of differential inputs. The voltage difference across the differential inputs is equalized by an equalizer and then applied to a multiplier and smoothed and filtered by a low-pass filter to produce an average signal. The average signal is compared to a reference voltage to detect when the voltage difference across the differential inputs is too small. A power-down signal is activated when the average signal is too small. The reference voltage compared can be generated by an equalizer, multiplier, and low-pass filter to match process, temperature, and supply-voltage variations in the primary signal path. The multipliers can be implemented with Gilbert cells. The equalizers can receive control signals to control attenuation of different frequency components. | 05-27-2010 |
20120087405 | Trace Canceller with Equalizer Adjusted for Trace Length Driving Variable-Gain Amplifier with Automatic Gain Control Loop - Distortions of both amplitude and phase along a transmission line are compensated for by a trace canceller inserted between a transmitter and a receiver. The trace canceller has an equalizer that compensates for a trace length between the transmitter and the trace canceller. A variable gain amplifier between the equalizer and an output buffer has its gain controlled by an automatic gain control circuit that compares low-frequency swings of the input and output of the trace canceller. The gain of the variable gain amplifier is reduced to prevent the output buffer from saturating and clipping peak voltages on its output. Thus both the variable gain amplifier and the output buffer remain in the linear region. Training pulses from the transmitter are passed through the trace canceller without clipping of peak voltages, allowing the transmitter and receiver to adjust transmission parameters to best match the transmission line. | 04-12-2012 |
20130049765 | In-Situ Cable Unplug Detector Operating During Normal Signaling Mode - An in-situ unplug detector circuit detects when a cable is disconnected or unplugged. Detection does not have to wait for normal signaling to pause, such at the end of a frame or timeout. Instead, detection occurs during normal signaling. When the cable is disconnected, the transmitter no longer drives the load at the far end of the cable, and thus can drive the near end to a higher high voltage and to a lower low voltage. The increased voltage swing is detected by a detector at the near end that amplifies the transmitter output to the cable. A fast detector has a higher bandwidth and faster response time than a slow detector, and generates a fast detect signal that crosses over a slow detect signal. When the cable is disconnected, the fast detect signal again crosses over the slow detect signal, and decision logic activates an unplug signal. | 02-28-2013 |

20110228365 | COMPUTER IMPLEMENTED METHOD FOR GENERATING BINARY HOLOGRAMS - A numerical method of recording a two or three dimensional object scene in a binary hologram. When the binary hologram is illuminated with a reference beam, the original object scene can be reconstructed and observed by a viewer. As the hologram is binary, i.e. composed of black or white pixels, it can be printed with commodity printers. The process is simple, fast, and economical, hence decreasing the cost and time for hologram design and production. In addition, with binary holograms, the ability to store the holograms is enhanced and binary holograms facilitate efficient transmission of the holograms. | 09-22-2011 |
