  • Patent number: 10187075
    Abstract: Residue generation systems for use in continuous-time and hybrid ADCs are described. An exemplary system includes a filter, e.g. a FIR filter, for generating a filtered analog output based on an analog input, a quantizer for generating a digital input to a feedforward DAC based on the filtered analog output generated by the filter, a feedforward DAC for generating a feedforward path analog output based on the digital input generated by the quantizer, and a subtractor for generating a residue signal based on the feedforward path analog output. Providing a filter that filters the analog input before it is quantized advantageously allows blockers to be attenuated before they are sampled and aliased by the quantizer. At least some of the residue generation systems described herein may be implemented with relatively small design and power dissipation overheads.

  • Patent number: 10181860
    Abstract: A residue generation apparatus for use in continuous-time and hybrid ADCs is proposed. The apparatus includes a quantizer for digitizing an analog input to generate a digital output, and means for applying a first transfer function to the digital output from the quantizer to generate a digital input to a feedforward DAC, based on which the DAC can generate a feedforward path analog output. The apparatus further includes means for applying a second, continuous-time, transfer function to the analog input provided to the quantizer to generate a forward path analog output, and a subtractor for generating a residue signal based on a difference between the forward path analog output and the feedforward path analog output. Proposed apparatus allows selecting a combination of the first and second transfer functions so that, when each is applied in its respective path, the residue signal passed to further stages of an ADC is reduced.

  • Patent number: 10130979
    Abstract: A method for improving the flatness of a rolled sheet or strip includes the application of differential cooling. A cooling agent can be selectively applied along the width of the strip. More cooling can be applied to the edges of the strip, where tension is greatest, to increase tension at the edges. The strip can be allowed to lengthen at these edges, which can improve flatness. In some embodiments, a closed loop flatness control system is used to measure the flatness of a strip and automatically adjust the differential cooling based on the measurement.

  • Patent number: 10129395
    Abstract: Systems and methods for visually indicating an occurrence of an incoming call for the hearing impaired are disclosed. A video communication device may be configured to receive an incoming communication to at least two unique identifiers assigned by a video relay service provider. The video communication device can display a unique visual indicator pattern, which may be user-created and user-assigned to the one of the at least two unique identifiers dialed by a caller. The visual indicator pattern may be indicative of the existence an incoming call, the origin of the call, the destination device for the call, the destination ID for the call, or combinations thereof. The video communication device, when receiving an incoming call, may send a wireless notification signal to other communication devices, thereby notifying other devices that a video communication device is receiving an incoming call.

  • Publication number: 20180275650
    Abstract: A controller of a motorcycle determines that the motorcycle is lane-splitting. The controller transmits a notification to vehicles in proximity to the motorcycle. In response to the notifications, the vehicles facilitate lane-splitting by the motorcycle. In particular the vehicles may flash lights to communicate that the vehicle has received the notification and will facilitate lane-splitting. The vehicles may facilitate lane-splitting by refraining from performing lane changes. The vehicles may further notify the motorcycle if lane changes are needed and the motorcycle controller may provide an alert to a rider.

  • Patent number: 10056914
    Abstract: A flash analog-to-digital converter (ADC) includes comparators that convert an analog input signal to a digital output signal. Offsets of these comparators introduce noise and can hurt the performance of the ADC. Thus, these comparators are calibrated using calibration codes. Conventional calibration methods determine these calibration codes by removing the ADC from an input signal. Otherwise, it is difficult to distinguish the noise from the signal in the calibration measurement. In contrast, an embodiment can determine the calibration codes while the ADC converts the input signal to a digital signal. Such an embodiment can be achieved by a frequency-domain technique. In an embodiment employing a frequency-domain power meter, an input signal can be removed from the power measurement. This removal enables accurate measurement of in-band noise without having the measurement be corrupted by input signal power.
