Patent number: 11016516Abstract: Energy packet switches (EPS) employing supercapacitors as storage provide aggregation and delivery of energy to users based on shared-capacitance in a digital power grid. The EPS aggregates energy from one or multiple energy sources, stores and dispatches the energy in discrete amounts as energy packets to one or multiple users. The payload of the energy packet is adjusted by the voltages of the supercapacitors which are used as energy containers for both the EPS and the users. The EPS has a control plane where data transmitted is used to control the operation of the EPS, and a power plane to receive and transmit energy between ports. The power and data planes work in parallel and with a parallel data network. Control and management of the EPS are based on a request-grant transport protocol. The data network is used to receive energy requests and grants, and a granting scheme is used to select which loads are granted energy.Type: GrantFiled: July 30, 2019Date of Patent: May 25, 2021Assignee: New Jersey Institute of TechnologyInventors: Roberto Rojas-Cessa, Haim Grebel, Zhengqi Jiang

Patent number: 7459687Abstract: Methods to infer the density of defects in high ? dielectric films in a non-contact, non-invasive and non-destructive manner. THz radiation is employed to measure the change in electrical conductivity of the films before and after illumination with visible light, where the visible light photoionizes the defects thereby changing the electrical conductivity and changing the transmission (or reflection) of THz radiation from the films. The disclosed techniques can be employed to make measurements as soon as wafers are fabricated. The technology is applicable to wafers of any size.Type: GrantFiled: April 6, 2007Date of Patent: December 2, 2008Assignee: New Jersey Institute of TechnologyInventors: John Francis Federici, Haim Grebel, Hakan Altan

Patent number: 7365699Abstract: A dipole array is provided for use as an Ultra Short Pulse (USP) transmitter or receiver in UWB communications systems, which reduces the output pulse dispersion. Instead of having all the dipole elements serially fed by a transmission line, the feeding in the array is made independently through a central point and the radiation is emitted and received broadsided with respect to the array plane. This configuration minimizes the relative time delay between radiating resonance frequencies.Type: GrantFiled: May 17, 2005Date of Patent: April 29, 2008Assignee: New Jersey Institute of TechnologyInventors: Haim Grebel, Nan Ni
