Patent number: 11426599Abstract: A neuromodulator includes one or more coil sets. Each of the coil sets has three coils aligned to produce magnetic and electric fields in three different directions. A plurality of conductors couple the coils of the one or more coil sets to one or more input signals such that each of the coils is independently activated via an individually selectable current applied through the conductors. The individual activation creates a resultant field that is a combination of the magnetic and electric fields in three different directions for each of the coil sets.Type: GrantFiled: November 22, 2019Date of Patent: August 30, 2022Assignee: Palo Alto Research Center IncorporatedInventors: Krishnan Thyagarajan, Bernard D. Casse, Christopher Paulson, George Daniel, Armin R. Volkel

Patent number: 11107645Abstract: A device includes at least one stress-engineered portion and at least one second portion. The stress-engineered portion includes at least one tensile stress layer having a residual tensile stress and at least one compressive stress layer having a residual compressive stress. The tensile stress layer and the compressive stress layer are mechanically coupled such that the at least one tensile stress layer and the at least one compressive stress layer are self-equilibrating. The stress-engineered portion is configured to fracture due to propagating cracks generated in response to energy applied to the stress-engineered portion. Fracture of the stress-engineered portion changes functionality of the device from a first function to a second function, different from the first function.Type: GrantFiled: November 29, 2018Date of Patent: August 31, 2021Assignee: Palo Alto Research Center IncorporatedInventors: Scott J.

Publication number: 20190296931Abstract: Connected consumer device systems are described. The consumer products associated with the systems can be powered or non-powered. The systems include one or more sensors to detect the state of the consumer product. An exemplary consumer product is designed to collect material and then be replaced once a desired amount of material is collected. The sensor is capable of detecting the existence and/or volume of material collected by the consumer product and is capable thereafter to communicate data to a hub and/or computing device. The communicated data can alert a consumer of a suggested action based on the data; for example, replace the consumer product as it has collected material. The communicated data can also trigger access to an e-commerce gateway to order more consumer products.Type: ApplicationFiled: June 11, 2019Publication date: September 26, 2019Inventors: Raj B.
