Characterizing Electric Scooter Riding Behavior To Detect Unsafe And Non-Compliant Use, Gabriel C. Terrell

Defensive Publications Series

The growing popularity of electric scooters has resulted in surfacing individual and public safety concerns associated with riding them. Many of these safety issues are associated with unsafe riding behaviors. While the terms of the riding agreements of scooter companies explicitly prohibit potentially unsafe riding behaviors, automatic and dynamic detection of unsafe riding is not easily possible simply from the location and speed data typically collected by the scooters. This disclosure proposes fitting an electric scooter with a weight-detecting mechanism that allows dynamic determination of riding behavior that indicates unsafe and/or impermissible use. Pattern recognition and/or machine learning is applied …

High-Density Voltage Regulator Using Dual-Fed Bridge Inductor, N/A

Defensive Publications Series

Data centers employ powerful CPUs and GPUs that consume significant amounts of current, e.g., up to a thousand amperes of current. To mitigate the large thermal losses in the power delivery network that occur at such high amperages, voltage regulators (VR) are moved closer to their loads, e.g., vertically below the loads. For a VR to fit in the tight space below the load, it must be of high density and integrate the decoupling capacitors that often occupy the space below the load. This disclosure describes a scalable, dual-fed-bridge (DFB) coupled inductor that is optimized for vertical power delivery. The …

Frequency Division Multiple Supply (Fdms) For Fast-Response Power Delivery, N/A

Defensive Publications Series

Traditional power delivery networks (PDN) to ASICs have a bandwidth that extends to about 100 kHz such that these PDNs respond with adequate speed and meet performance specifications if the transient load current changes at a rate slower than 100 kHz. As ASICs become more computationally powerful, not only does their current consumption go up, their current transients undergo relatively rapid slew, e.g., with a bandwidth exceeding 10 MHz. The bandwidth mismatch between the PDN and the current demand of the ASIC causes a substantial loss in efficiency.

This disclosure describes a PDN comprising an ensemble of three or more …

Board Identifier (Boardid) Locked Firmware Images, Randall R. Spangler

Defensive Publications Series

This publication describes a method for a firmware developer to push out re-writable (RW) firmware images that support legacy-generation, current-generation, and future-generation boards. To do so, the firmware developer uses a minimum of three (3) 32-bit-writable words that describe a board identifier, herein called BoardID. The BoardID contains three (3) fields, which describe a board type, an inverse of the board type, and flags. This BoardID solution allows the firmware developer to push out RW firmware that are not as universal and global as traditional mass-production firmware images and are not as unique as node-locked firmware images.
