Abstract: Systems and methods of generating metrics for volatility products are disclosed. According to various embodiments, the metric may use a carry of the volatility product and a volatility of the implied volatility to determine the metric. Through the metric, or carry quotient, global interest rate volatility may be searched to identify trades with attractive rolldown and carry characteristics.

Abstract: Load driver system (10) preferably uses a microprocessor controller (20) to generate write/read signals and command signals received by a circuit at write/read and command/status input terminals (16, 17). The circuit (15) responds to the input signals and controls a semiconductor switch (11) that controls the operative state of a load (14). The circuit (15) includes a load shorted high detector (28), a load shorted low detector (29) and a load open detector (30) which are used to detect various faults and provide a predetermined sequence of logic states at the command/status input terminal (17) during read cycles implemented by the controller (20). Thus one input line (terminal 17) is used to both send commands to the semiconductor switch (11) and receive a sequence of logic states indicative of various fault modes. This permits the controller to determine which of several types of faults, if any, has occurred, while minimizing the number of controller-circuit interconnections.

Abstract: A pair of golf gloves for teaching a golfer to maintain his grip about a golf club during a golf swing. The pair of golf gloves comprises of a control-hand glove which fits about a golfer's control hand and a power-hand glove which fits about a golfer's power hand. The control-hand and power-hand gloves are designed with an audible emitter which audibly signals to the golfer when the golfer's hands initially begin to break or separate during the golf swing. The audible emitter consists only of a first cooperating VELCRO.RTM. section strategically attached to the control-hand glove and a second VELCRO.RTM. section strategically attached to the power-hand glove. The first VELCRO.RTM. section located about the palm side of the base area of the thumb of the control-hand glove, and the second VELCRO.RTM. section located about the palm side along the lower base area of the power-hand glove. The cooperating first and second VELCRO.RTM.
