Abstract: Subscribers can access and listen to their email while they drive, access to the email messages being hands-free so a person can listen to email while they drive. In further accord with the present invention, a selectable avatar speaks the email message. And, the invention provides unified messaging such that SMS and email are unified and present and spoken by the avatar, so the subscriber need not access two devices (an instant message device, and an email device). Additionally, the invention can convert natural language to an acronym to be spoken by the avatar, and can convert acronyms in a message to natural language spoken by the avatar; subscriber selects the desired one of these two.

Abstract: ILLUM-A-FIELDR Modification of Medical and Laboratory Instruments encompasses attaching a LED Assembly to medical, laboratory and other instruments and tools. Power to said assembly is a portable, lightweight, rechargeable power supply. Major advantages include field portability; use in hostile environments including battlefield conditions and civilian emergency situations; can be supplied with extremely long shelf-life batteries; can be used as emergency lighting due to the light output of the device. It has been shown to effectively reduce working time in histology and pathology laboratories. ILLUM-A-FIELDR's ability to work submerged makes this a substantial improvement of medical instruments used in burn centers where patients must remain under water and other applications where a submersible implement would be of benefit.

Abstract: A system for supplementing an audio signal with auxiliary data in an inaudible channel. The system can include an audible radio signal source having at least a left channel and a right channel. A digital signal processor can be programmed to transform the audible radio signal source into a frequency domain representation having multiple frequency component portions of the audible radio signal. A comparator can be coupled to the digital signal processor and can have an established imperceptible IPD. The comparator can identify selected ones of the frequency component portions having corresponding phase values which do not exceed the imperceptible IPD. Finally, an encoder can be configured to encode a digital auxiliary data signal into the audible radio signal by modifying the corresponding phase values to correspond to individual bit values of the digital auxiliary data.
