Patent number: 10749450Abstract: An electrostatic clutch is described comprising a plurality of micron-scale thickness electrodes, adjacent electrodes being separated by a thin film of dielectric material. A power source and controller apply a voltage across two electrodes, causing an electrostatic force to develop. When engaged, a force can be transferred through the clutch. A tensioning device maintains the alignment of the clutch when the electrodes are disengaged, but permits movement in at least one direction. In some embodiments, multiple clutches are connected to an output to provide variable force control and a broad range of torque input and output values. Moreover, the clutch can be used as an energy-recycling actuator that captures mechanical energy from negative work movements, and returns energy during positive work movements.Type: GrantFiled: June 3, 2019Date of Patent: August 18, 2020Assignee: CARNEGIE MELLON UNIVERSITY, a Pennsylvania Non-Profit CorporationInventors: Carmel Majidi, Steven Collins, Stuart Diller

Patent number: 10039651Abstract: The disclosure describes a direct skeletal attachment (DSA) device including a micro-miniature chainmail skin-to-DSA interface. The interface comprises various porous architectures for skin ingrowth and integration as barriers against pathogens. Failure of skin-to-DSA interfaces can occur due to mismatches in mechanical compliance between pliable skin and more rigid DSA interfaces. To address this problem, in embodiments disclosed herein is an interface having a gradient in mechanical compliance or link mobility, ranging from fully flexible, to less compliant, to rigid where it attaches to the main DSA body.Type: GrantFiled: January 14, 2016Date of Patent: August 7, 2018Assignee: CARNEGIE MELLON UNIVERSITY, a Pennsylvania Non-Profit CorporationInventors: Lee E. Weiss, Gary K. Fedder

Patent number: 9927512Abstract: An indoor ultrasonic location tracking system that can utilize standard audio speakers to provide indoor ranging information to modern mobile devices like smartphones and tablets. The method uses a communication scheme based on linearly increasing frequency modulated chirps in the audio bandwidth just above the human hearing frequency range where mobile devices are still sensitive. The method uses gradual frequency and amplitude changes that minimize human perceivable (psychoacoustic) artifacts derived from the non-ideal impulse response of audio speakers. Chirps also benefit from Pulse Compression, which improves ranging resolution and resilience to both Doppler shifts and multi-path propagation that plague indoor environments. The method supports the decoding of multiple unique identifier packets simultaneously. A Time-Difference-of-Arrival pseudo-ranging technique allows for localization without explicit synchronization with the broadcasting infrastructure.Type: GrantFiled: January 10, 2014Date of Patent: March 27, 2018Assignee: Carnegie Mellon University, a Pennsylvania Non-Profit CorporationInventors: Anthony Rowe, Patrick Lazik

Patent number: 9830813Abstract: Scalable urban traffic control system has been developed to address current challenges and offers a new approach to real-time, adaptive control of traffic signal networks. The methods and system described herein exploit a novel conceptualization of the signal network control problem as a decentralized process, where each intersection in the network independently and asynchronously solves a single-machine scheduling problem in a rolling horizon fashion to allocate green time to its local traffic, and intersections communicate planned outflows to their downstream neighbors to increase visibility of future incoming traffic and achieve coordinated behavior. The novel formulation of the intersection control problem as a single-machine scheduling problem abstracts flows of vehicles into clusters, which enables orders-of-magnitude speedup over previous time-based formulations and is what allows truly real-time (second-by-second) response to changing conditions.Type: GrantFiled: October 12, 2015Date of Patent: November 28, 2017Assignee: CARNEGIE MELLON UNIVERSITY, a Pennsylvania Non-Profit CorporationInventors: Stephen F.

Patent number: 9797187Abstract: Devices that incorporate phase change materials in containment vessels promote conduction of thermal energy between the phase change materials within the containment vessels and the surrounding air. In some embodiments, the containment vessels are transparent to enable visual awareness of the operation and functionality of the PCMs. In some embodiments, the containment vessels are design to passively promote air flow across the surfaces of the containment vessels. In some embodiments, the containment vessels include embedded structures to promote the conduction of thermal energy to and from the interior of the containment vessel. In some of these embodiments, the intent is to target the location of crystal ‘seeds’ and control crystal growth, thus gaining greater control over thermal transfer.Type: GrantFiled: January 14, 2014Date of Patent: October 24, 2017Assignee: Carnegie Mellon University, a Pennsylvania Non-Profit CorporationInventors: Dale Timothy Clifford, Shi-Chune Yao

Publication number: 20170236518Abstract: Disclosed herein is a GPU-accelerated speech recognition engine optimized for faster than real time speech recognition on a scalable server-client heterogeneous CPU-GPU architecture, which is specifically optimized to simultaneously decode multiple users in real-time. In order to efficiently support real-time speech recognition for multiple users, a “producer/consumer” design pattern is applied to decouple speech processes that run at different rates in order to handle multiple processes at the same time. Furthermore, the speech recognition process is divided into multiple consumers in order to maximize hardware utilization. As a result, the platform architecture is able to process more than 45 real-time audio streams with an average latency of less than 0.3 seconds using one-million-word vocabulary language models.Type: ApplicationFiled: February 16, 2017Publication date: August 17, 2017Applicant: CARNEGIE MELLON UNIVERSITY, a Pennsylvania Non-Profit CorporationInventors: Ian Richard Lane, Jungsuk Kim

Publication number: 20170236057Abstract: Disclosed herein is a deep learning model that can be used for performing speech or image processing tasks. The model uses multi-task training, where the model is trained for at least two inter-related tasks. For face detection, the first task is face detection (i.e. face or non-face) and the second task is facial feature identification (i.e. mouth, eyes, nose). The multi-task model improves the accuracy of the task over single-task models.Type: ApplicationFiled: February 16, 2017Publication date: August 17, 2017Applicant: CARNEGIE MELLON UNIVERSITY, a Pennsylvania Non-Profit CorporationInventors: Ian Richard Lane, Bo Yu
