Abstract: A diving helmet apparatus includes a diving helmet that is based on a 98th percentile anthropomorphic head form. The helmet is relatively smaller and lighter than convention diving helmets. The center-of-gravity and center-of-buoyancy of the helmet are co-located to reduce diver fatigue. The apparatus has unique neck dam latch devices that use cam mechanisms. The neck dam and the opening in the helmet that receives the diver's head both have a substantially oval shape that contributes to a significant reduction in the volume of the helmet. The apparatus also uses unique face mask latch devices. The neck dam and face mask latch devices allow a diver to easily secure and remove the helmet and face mask without the assistance of dive tenders.

Abstract: A tunable contact microphone is fabricated from nanometer size piezoelectric materials. The piezoelectric nanostructures are deposited on a flexible substrate or tunable resonant backplane. The backplane can be designed to vibrate at fundamental harmonic or sub-harmonic frequencies from 10 Hz to 20 KHz, corresponding to vibration frequencies of the human cranium. The backplane can be attached to a band or other material that will facilitate the attachment to the forehead, behind the ear or throat, with a preferred location being the forehead. When a person speaks, the backplane vibrates causing the nanostructures to generate electricity. The electrical signals are sent to an impedance matching preamplifier. The signal can then be sent to a communications system or fed into the microphone input of a communication system.

Abstract: A padlock having a locking mechanism that can be unlocked using a thumbwheel, by a traveler, or by secured key, by a TSA or government agent. The Padlock has a timer that prevents the lock from unlocking for a set period of time. The padlock also has a switch that activates the activation of the timer. The activation of the timer activates the timer so that the lock cannot be unlocked until the following sequence is completed: first the padlock unlocking mechanism is activated by dialing the correct code on the thumbwheel of the padlock and thereby starting a set time period for the automatic release of the padlock and second by the lock automatically unlocking after the set period expiring. The padlock also has a bypass mechanism that bypasses the timer sequence and thereby unlocks the lock. The padlock may also have at least one light that notifies a handler of the padlock of the activation of the timer and/or the release of the padlock.

Abstract: A system and a method are disclosed for accessing the need and ability of an organization such as a business to use a financial product. The need is related to the length of time it takes the organization to receive payment after making a sale, and whether the organization receives payment for the sale. The need is greatest for an organization with a high bad debt ratio or slow average time until payment is received. The ability of the organization to pay for the financial product is greater when gross profit margin is high. The total volume of sale can also be taken into account in determining whether the organization can use the financial product.
