Secure Communications System for Direct Transfer Between Mobile Device

Apparatus and associated methods relate to securely transmitting, directly between two mobile devices, AES-256 encrypted file attachments which are decrypted within an application program (APP) using a decryption key that is available only to the APP. In an illustrative embodiment, the encrypted file may be attached to an e-mail. The e-mail may be transmitted directly to another mobile device via direct Wi-Fi, for example. The e-mail may be transmitted directly to another mobile device using Bluetooth, for example. In encrypted attachment may be deciphered only within the APP running on the receiving mobile device using a private key accessible to only the APP.

Wireless Telemetry Auto Tuning For Torque Measurement System

A torque measurement system that includes a rotor device and a stator device can perform automatic tuning to improve the initial tuning performed during design and assembly. The stator device can include a variable capacitive

Vibrational Alarms Facilitated by Determination of Motor On-Off State in Variable-Duty Multi-Motor Machines

Apparatus and associated methods relate to a vibrational sensing system (VSS) including an accelerometer and a data processor, which determines an “operational state” of a mechanical drive unit, the processor further employing the “operational state”

Virtual Mask Fitting System

Apparatus and associated methods relate to determining a fit-quality metric for a mask/face combination based upon a calculated dead-space volume between a virtual mask and a virtual face virtually aligned so as to create an

Voltage Regulator with Piecewise Linear Loadlines

Apparatus and associated methods relate to providing a piecewise loadline having a number of segments with different slopes and selecting a segment of the piecewise loadline based on an output current of a power supply.
