Abstract: The present invention is a system that allows users to bid on time slots of a video conferencing resource 10 using market orders and limit bid orders denominated in tokens of different values. The users are provided with a display 110 that shows the current bids and orders along with their account balance and allowed to place orders using tokens. The slots are allocated immediately when a market bid equals a market price and allocated to the highest bidder at an end of a bidding period for limit orders when a market order has not already captured the time slot. Winning order holders are informed about the allocation of the time slots with a confirmation display 200. The users allocated the time slots have a priority specified by the cost of the time slot in tokens and can be disabled from using the time slot after use has started.

Abstract: A method of determining whether an individual has Attention Deficit Hyperactivity Disorder (ADHD) comprising: sampling the peripheral skin temperature of a human subject during a predetermined time interval when the subject is in an inactive state to provide a sampled peripheral skin temperature signal containing noise: modulating said sampled peripheral skin temperature signal containing noise with a known reference signal to produce a modulated signal; inputting said modulated signal and said known reference signal to a lock-in amplifier to produce a sampled peripheral skin temperature signal free of said noise; and analyzing the sampled peripheral skin temperature signal for a pre-selected parameter to determine whether said predetermined parameter has a value indicative of ADHD.

Abstract: An electro-optic light modulator of the type including a body of an electro-optic material having opposed surfaces and a pair of planar conductive electrodes on at least one of the surfaces of the body. Polarity-reversing drive circuitry applies a voltage across the electrodes, the polarity of the voltage being reversed at a frequency of about 1 Hz or less with polarity reversal occurring either when the light modulator is turned off or when there is an insignificiant voltage drop across the electrodes. This low frequency of the reversal of the polarity of the voltage substantially eliminates drift of the voltage-transmissivity of the modulator, lowers leakage, and reduces damage to the electrodes during a given period of time of operation.
