Abstract:

A safety shutdown system for a rotary drill rig with a power supply, a support frame and a rotary drill spindle and drill tool connected to the support frame. The drill spindle and tool are driven by a drive train that is connected by a clutch with a declutch mechanism to an internal combustion engine and an engine solenoid with a shut-off switch. A brake with a brake solenoid is also provided on the drive train. An infrared beam transmitter is positioned adjacent to the drill tool and an infrared beam receiver is positioned adjacent to the drill tool and on the opposite side of the drill from the transmitter so that the receiver can receive infrared beams emitted from the transmitter. A controller is connected between the clutch solenoid and the engine solenoid. The controller is activated when the infrared beam between the transmitter and the receiver is interrupted.

Abstract:

A method and system for setting the optimal price for a hotel property are described. The method includes the steps of receiving electronic data having marketing information, including, for example, the customers won and lost by competitors. One or more price sensitivity coefficients are calculated based on the market data. The price sensitivity coefficients are used to calculate a predicted share value representing the probability that a next customer will book a property at the subject hotel at a particular price. The price sensitivity coefficients are also used to calculate a price elasticity value representing the responsiveness of demand for the hotel property to a change in the price of that property. The price of the hotel property is set at a point where the price elasticity value is substantially equal to −1.0.
