  • Publication number: 20200264558
    Abstract: A two-step optimization process is utilized to define an optimal phase profile for a LCoS spatial light modulator. The two-step optimization process first utilizes a nonlinear constrained optimization (NCO) program to determine the specific parameters required to obtain an optimal phase profile (hologram), where the “optimal phase profile” is typically defined as that profile which achieves maximum diffraction efficiency for optical switching. Following this first step, phase scaling (and perhaps an adjustment in the number of pixels per period) is employed to slightly modify the values of the optimal phase profile to effectively suppress crosstalk peaks. If any orders still exhibit an unacceptable level of crosstalk, these orders are then subtracted from the phase profile to create the final design.

  • Publication number: 20200259465
    Abstract: Disclosed are methods, systems, devices, apparatus, media, and other implementations, including a method for digital predistortion for a power amplifier system. The method includes determining one or more system characteristics for the power amplifier system comprising at least a power amplifier that produces output with non-linear distortions, with the one or more system characteristics corresponding to an estimate for a complex load metric for the power amplifier system coupled to a load. The method further includes determining, based on the one or more system characteristics corresponding to the estimate for the complex load metric, digital predistortion (DPD) coefficients to compensate for the nonlinear behavior of the power amplifier system.

  • Patent number: 10736464
    Abstract: A food preparation device or system which utilizes pre-packaged food containers to prepare a food item for consumption. The food preparation device is structured to receive multiple pre-packaged containers. Additionally, the food preparation device includes one or more processors to verify that each of the multiple containers include one or more ingredients for preparing a selected dish, and further that an order in which the multiple containers are individually received in the base corresponds to a sequence in which the individual food items of the multiple containers are to be introduced into a cooking receptacle during preparation of the dish.

  • Publication number: 20190363676
    Abstract: Disclosed are systems, devices, modules, methods, and other implementations, including a method for digital predistortion that includes receiving, by a digital predistorter, a first signal that depends on amplitude variations based on an input signal, u, with the variations of the first signal corresponding to time variations in non-linear characteristics of a transmit chain that includes a power amplifier. The method further includes receiving, by the digital predistorter, the input signal u, generating, by the digital predistorter, based at least in part on signals comprising the input signal u and the first signal, a digitally predistorted signal v to mitigate the non-linear behavior of the transmit chain, and providing the predistorted signal v to the transmit chain.

  • Patent number: 10367596
    Abstract: A multiple wavelength selective switch has an optics assembly to receive a first input optical signal from a first ingress port and a second input optical signal from a second ingress port. A switch assembly has a single switching mechanism to direct the first input optical signal to the optics assembly as a first output optical signal and the second input optical signal to the optics assembly as a second output optical signal. The switch assembly directs the first output optical signal to a first egress port selected from the first set of egress ports and directs the second output optical signal to a second egress port selected from the second set egress ports. The first egress port and the second egress port have the same wavelength channel. The multiple wavelength selective switch supports an arbitrary number of wavelength channels that can be switched at the same time. Each switch assembly directs signals from a set of ingress ports to a set of egress ports sharing the same wavelength channel.
