  • Patent number: 11185823
    Abstract: A system includes an electrodialysis device with a salinate chamber through which a salinate stream flows. A desalinate chamber is separated from the salinate chamber by a central, ion-selective membrane. A desalinate stream flows through the desalinate chamber. An anolyte chamber and a catholyte chamber are on opposite outer sides of the salinate and desalinate chambers and separated therefrom by first and second ionic exchange membranes. A solvent exchange interface is in contact on a first side with the salinate stream and is in contact a media flow on a second side. The solvent exchange interface moves a solvent from the media flow to the salinate stream.

  • Patent number: 11182114
    Abstract: One embodiment provides a system for facilitating device discovery. During operation, the system detects, by a computing device, a first message which is broadcast from a source device based on a network communication protocol. The system determines a classification which is a type for the source device based on a MAC address of the source device extracted from the first message. The system generates a second message which indicates the MAC address, an IP address of the source device obtained based on the first message, and the classification. The system sends the second message to a device management system, which causes the device management system to add the source device as a managed device. The system enhances device discovery by eliminating a direct scan of all devices on a sub-network by the device management system for devices of a same type as the type for the source device.

  • Patent number: 11157672
    Abstract: One embodiment of the present disclosure provides a system for determining a hybrid-manufacturing plan for manufacturing an integrated circuit (IC). During operation, the system can obtain a set of hybrid-manufacturing constraints for manufacturing the IC. The set of hybrid-manufacturing constraints can include a set of primitives, a set of atoms, and an atom end-state vector. An atom can correspond to a unit of spatial volume of the IC. A primitive can represent an additive, subtractive, or a mixed manufacturing process corresponding to one or more atoms of the IC. Next, the system can determine a plurality of feasible hybrid-manufacturing plans based on the set of manufacturing constraints. Each feasible hybrid-manufacturing plan can represent an ordering of the set of primitives that satisfies the atom end-state vector. The system can then determine costs for manufacturing the IC using the plurality feasible hybrid-manufacturing plans.

  • Patent number: 11151494
    Abstract: A system and method for visualizing parking enforcement officer movement in real time with the aid of a digital computer is provided. A time-based active representational model of the city is created by fusing sensory data collected from various sources around a city with numerical data gleaned from historical and on-going activities, including parking regulation citation and warning numbers, resource allocations, and so on. The model can be used to form quantitative predictions of expected violations, revenue stream, and so forth, that can then be used as recommendations as to where to enforce and when, so as to maximize the utilization of the limited resources represented by the officers on the street. Moreover, the performance of the officers can be weighed against expectations of performance postulated from the quantitative predictions.

  • Patent number: 11141585
    Abstract: A neuromodulator includes an electromagnetic (EM) wave generator configured to generate EM waves remote from a patient and to direct the EM waves to one or more target regions within the patient. Frequencies of the EM waves fall outside a range of frequencies that activates neurons. Intersection of the EM waves in each target region creates envelope-modulated electric and magnetic fields having one or more frequencies that fall within the range of frequencies that activates neurons. The neuromodulator includes control circuitry configured to control parameters of the EM waves produced by the EM wave generator. The neuromodulator may use feedback based on one or more of patient input and/or sensing of physiological signals in order to close the loop and control the EM waves.
