Patent number: 11701271Abstract: An agent activated non-metal antenna for an ultra-high frequency (UHF) wireless sensor having a radio frequency identification (RFID) tag in electronic communication with the non-metal antenna, and a wireless data communication integrated circuit (IC), includes a conductive stimuli-responsive hydrogel material configured to be inactive prior to an interaction with an activating agent and active upon the interaction with the activating agent. The antenna is further configured to transmit power to turn on the wireless data communication IC only when the non-metal antenna is active upon interaction with the activating agent.Type: GrantFiled: October 28, 2021Date of Patent: July 18, 2023Assignee: Massachusetts Institute of TechnologyInventors: Sanjay E. Sarma, Rahul Bhattacharyya, Joshua E. Siegel, Alex Armengol Urpi, Pankhuri Sen, Sai Nithin Reddy Kantareddy

Patent number: 10637951Abstract: Systems and methods are provided for managing data proxies. The systems and methods enable a proxy management system to store and manage data proxies that digitally represent real-world objects equipped with sensors. The data proxy of an object is made up of data sampled by the object's sensors and data estimated using the sampled data. The sampling rate at which the data is sampled can be optimized such that it conforms with target quality of data (QoD) requirements and/or target data acquisition costs. The QoD requirements can be based on requirements set by each of the applications associated with an object. The proxy management system can use the sampled data and estimated data to (1) ensure that incoming messages, if executed, would not have negative consequences; and (2) monitor objects to determine if and when they are expected to approach undesirable states, or if they have already reached such undesirable states.Type: GrantFiled: April 10, 2017Date of Patent: April 28, 2020Assignee: Massachusetts Institute of TechnologyInventors: Joshua E. Siegel, Sanjay E. Sarma

Patent number: 10315659Abstract: An apparatus for a clutchless manual transmission includes a transmission, a drive shaft, and a motor shaft. The transmission includes an input shaft, an output shaft, and an intermediate gear. The input shaft is coupled to an engine shaft to receive power and the output shaft is coupled to the drive shaft to transmit power to a wheel of a vehicle. The input shaft and output shaft are coupled by a plurality of input and output shaft gears. A first synchronizer is coupled to the output shaft to selectively engage a particular output shaft gear, adjusting the speed of the output shaft relative to the input shaft. The motor shaft receives power from a motor and includes a second synchronizer to selectively engage the engine shaft to the drive shaft via the motor shaft. The apparatus can be used to reduce acceleration and turbo lag in hybrid and high-performance vehicles.Type: GrantFiled: January 25, 2018Date of Patent: June 11, 2019Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Chad L. Jacoby, Jacob M. Jurewicz, Joshua E. Siegel, Amos G. Winter, V, Young Suk Jo, Patricia Yen, Guillermo Pamanes Castillo, Daniel Scott Dorsch

Patent number: 10052824Abstract: Systems, devices, and methods for three-dimensional printing are provided. The systems, devices, and methods provide for high throughput printing by allowing for parallel extrusion within a single vertical layer of the printed object, i.e., parallel extrusion within an x-y coordinate plane. Any advancement of an extruder can be limited to movement along a single axis, or even no axis at all, so that printing occurs more quickly. In some embodiments, the extruder can include a printing plate that includes a plurality of apertures defined by conductive elements extending in a grid-like manner. The printer can be designed such that material is disposed to a build platform through the apertures only when the aperture is heated on all four sides, for instance by running current through the conductive elements that define the aperture. Other systems, devices, and methods for three-dimensional printing are also provided.Type: GrantFiled: May 13, 2015Date of Patent: August 21, 2018Assignee: Massachusetts Institute of TechnologyInventors: Dylan C. Erb, Joshua E. Siegel, Isaac M. Ehrenberg, Pranay Jain

The input shaft includes a transmission input gear and a plurality of input shaft gears. The output shaft includes a transmission output gear and a plurality of output shaft gears. The input shaft and the output shaft are aligned such that the input shaft gears mesh with the output shaft gears. The output shaft includes a first synchronizer configured to selectively engage an output shaft gear from the plurality of output shaft gears to adjust a ratio between an input shaft speed and an output shaft speed. The transmission output gear is operably coupled to the drive gear such that power is transmitted between the transmission output gear and the drive gear when the output shaft gear is engaged.Type: ApplicationFiled: January 25, 2018Publication date: May 31, 2018Inventors: Chad L.
