Abstract: Devices, systems, and techniques are disclosed for verifying the occurrence of an acute health event. An example device includes communication circuitry configured to receive a communication indicative of an acute health event of a patient and memory communicatively coupled to the communication circuitry and being configured to store the indication of the acute health event. The device includes processing circuitry communicatively coupled to the communication circuitry and the memory. The processing circuitry is configured to, in response to the communication, verify the acute health event and based on the verification of the acute health event, send an alert regarding the acute health event.

Abstract: A financial instrument, exchange, and method based upon the volatility in the price of an underlying. Such volatility contracts have a creation date, a term expiring at an expiration date, and a settlement price at the expiration date defined as “Svol”, under the formula: Svol?f{Rt1,Rt2,Rt3, . . . , Rtn}, wherein: Svol?0, n>1, t=each of a series of observation points from 1 to “n”; Rt=return of the underlying based upon each of the observation points in time “tn”; and n=total number of observations within the term. The term is selected from the group consisting of days, months, quarters and years. The settlement price is annualized based upon an approximate total number of periods in a calendar year. Rt is selected from the group consisting of: R t = ln ? ( M t M t - 1 ) ? ? and ? R t = ( M t - M t - 1 M t - 1 ) wherein: Mt=mark-to-market price at time “t”; and Mt?1=mark-to-market price at the time immediately prior to time “t”, at time “t?1”.
