Health Care - Portable Pump
Design of a battery management embedded process to ensure the ‘ready to deploy’ capability was maximised for a pump(compressor) used by Ambulance Services, Worldwide medical fall teams and Care Homes. The design complexity included the use of deconstruct-able battery packs requiring reduced charge time for the integrated battery system after each deployment i.e. from 16 hours to 3 hours. Regulating the self-discharge by firmware to supply a regular ‘top-up’ charge based on time elapsed without deployment. An energy saving mode that automatically starts after a full charge and seamlessly integrates with the self-discharge ‘top-up’ process. Simple continual indication of the battery remaining capacity and time to full charge that also incorporates the energy saving mode. Counting the number of lifts performed to estimate the depth of dis-charge and the re-charge time required hence extending the life of the battery and minimising the planned maintenance.

Energist (Nov 2022 - July 2023)
Chief Technology Officer
High Profile assignment with a Medical company focused on skin care / rejuvenation for both medical and cosmetic applications. Technology was microwave (High Frequency RF) energy for plasma generation. Product design using SolidWorks and parts supplied from CMM Ltd China. Optimising the creation of Corona discharge to accomplish consistent transfer of plasma thermal energy to the epidermis. Managed an RF cable assembly transfer from Sub-Contract to In-House improving Quality and reducing costs by 50%. Introduced Six Sigma Technology into the Test and CAPA Process. Distributor visits that included Soal in South Korea.
Defence & Security
The design of an encryption/decryption device for a Defence company. This device and its associated circuitry formed a Crypto Kernel. An in-house FPGA was developed using the Advanced Encryption Standard Algorithm The interfaces to the Crypto Kernel Module was provided by the RED Line Interface for plain text, and the BLACK Line Interface for cipher text as shown. Functional Control of the Crypto Kernel Module was performed by the Crypto Management Module. This also included an SNMP interface, allowing the functional state of the equipment to be interrogated by a network management centre.
