Mobile Apps for Android and iOS. Our inaugural product is ScrollTuner for Android. This is a chromatic musical tuner that analyzes and records your tuning performance while you play real music then lets you go back and review on a graphic display.

As the company’s sole specialist in signal processing and analysis, developed and delivered solutions to critical problems that were limiting product viability in each of the three major sequential product focuses of Cold Bore since it’s inception: 1. Sonic Telemetry for MWD downhole data communication: significantly improved the noise floor operation of sonic sensors; uncovered a fundamental flaw in the down-hole transmitter and redesigned the surface receiver to accommodate; improved receiver algorithm design and demonstrated significantly increased depth of operation during field trials on commercial oil drilling rigs; developed and implemented a Bluetooth based means of interfacing to the drill-pipe mounted telemetry receiver to stationary equipment. Patents filed and granted.2. Sliding Sleeve Fracking Completions Operations: designed and implemented an ambient noise reduction algorithm using multiple sonic sensors to enable detection of weak down-hole sonic events, providing a substantial advantage over competitors. Also developed and implemented method of tracking down-hole collet travel using pressure transient analysis. These systems are still being deployed and providing a revenue stream. Patents pending.3. Zipper-Frac Completions Operations: developed a fault-tolerant sensor-based method of tracking and recording critical operation activities of multiple wells on a well-site. This is a critical/core component of Cold Bore’s primary product and revenue stream, SmartPAD. Patent pending.

DSP / Digital system architect for PMC's latest generation SerDes operating at up to 28Gbps, working closely with the analog architecture and design team. Responsible for overall receiver architecture strategy, equalization, adaptation, timing recovery, and BER performance projections using detailed end-to-end system simulation model of anticipated SerDes links.Strategic investigations into analog equalization architecture alternatives for advanced SerDes products.Strategic investigations into DSP methods that will benefit PMC's wireless product roadmap.Examples of some key accomplishments: A) Selected to be the primary technical DSP lead for the overall architecture design of PMC's latest generation SerDes operating at up to 28Gbps. The new architecture significantly reduces power consumption relative to previous generation, achieving Best-In-Class power performance.B) Developed strategy and algorithm for adapting an analog equalization filter to provide the necessary BER performance over operational data rates ranging from 5Gbps to 28Gbps. A key feature prevents timing recovery from fighting with filter adaptation. Patents filed: US #13/957,852 and #13/941,902C) Conducted performance analysis of end-to-end SerDes link, using customer specified backplane and cable channel models, to demonstrate viability of 1E-18 BER target using a combination of transient and statistical methods in a Matlab environment. Detailed simulation/analysis results were successfully reviewed internally and with customers.
