Computer apparatus and method for generating documentation using a computed value for a claims cost affected by at least one concurrent, different insurance policy for the same insured

A method for using a digital electrical apparatus to electrically process signals in generating output for insurance documentation for a first insurance policy for a first risk having a claims cost reflecting: a concurrent second insurance policy for a second risk, the second risk being different from the first, the policies being for the same insured person, and the second policy affecting a claims cost of the first policy; the method including the steps of: in a digital electrical computer apparatus comprising a digital computer having a processor, the processor electrically connected to a memory device for storing and retrieving operations including machine-readable signals in the memory device, to an input device for receiving input data and converting the input data into input electrical data, to a visual display unit for converting output electrical data into output having a visual presentation, to a printer for converting the output electrical data into printed documentation, wherein the processor is programmed to control the apparatus to receive the input data and to produce the output data by steps including: inputting actuarial assumptions defining the first insurance policy; and computing a value of a specific financial attribute of the first insurance policy; the method further including the step of inserting the value of the financial attribute in the first insurance policy and other printed documentation related to the first insurance policy.

Use of downhole high pressure gas in a gas-lift well and associated methods

A gas-lift petroleum well and method for producing petroleum products using downhole pressurized gas to provide lift. The gas-lift well having a well casing, a production tubing, a packer, and a gas-lift valve. The well casing extends within a wellbore of the well, and the wellbore extends through oil and gas zones. The production tubing extends within the casing. The tubing having an opening formed therein, which is in fluid communication with an oil zone. The packer is located downhole in the casing and coupled to the tubing. The packer can have an electrically controllable packer valve, which is adapted to control a flow of downhole pressurized gas from one side of the packer to another. The downhole pressurized gas is provided by a gas zone that the wellbore passes through. The downhole gas-lift valve is coupled to the tubing and is adapted to control a flow of downhole pressurized gas into oil in the tubing for lifting the oil. The gas-lift valve can be an electrically controllable valve. The tubing and casing are used as electrical conductors for supplying power and/or communications downhole. The current in the tubing is routed using a ferromagnetic induction choke to create a voltage potential, which provides electrical power to downhole electrical devices. Also, there may be a bypass passageway to route downhole gas to gas-lift valves. There may also be downhole sensors to measure physical quantities (e.g., pressure). Such measurements can be used for feedback control of downhole electrically controllable valves.

Electrical generator having an oscillator containing a freely moving internal element to improve generator effectiveness

An apparatus and method for providing electrical energy to an electrical device by deriving the electrical energy from motion of the device. In one embodiment, the inventive apparatus includes a novel kinetic electrical power generator (KEPG) consisting of an inventive oscillating weight having an internal cavity with a freely movable acceleration element disposed therein, resulting in improved acceleration and oscillation capabilities and lower motion threshold for the weight, a system for converting the weight's oscillating motion into rotational motion, and an electromechanical transducer system for generating electrical energy from the rotational motion. The novel KEPG includes components for modifying the electrical energy for storing and/or feeding the modified electrical energy to the electrical device. Optional components may be included for using the modified electrical energy to recharge one or more rechargeable batteries used in an electric device. Alternate advantageous embodiments of the inventive apparatus include, but are not limited to: a KEPG with multiple inventive oscillating weights to increase velocity and frequency of desirable rotational motion, and a KEPG system utilizing multiple electrically coupled KEPG sub-systems.
