A reduced multicubic database interpolation method is provided. The interpolation method is designed to map a function and its associated argument into an interpolated value using a database of points. The database is searched to locate an interpolation cell that includes the function argument. The interpolation cell is used to transform the function argument to reflect translation of the interpolation cell to a unit cell. The interpolated value is then generated as a cubic function using the data points that correspond to vertices of the unit cell. All of the derivatives in the cubic function are simple and the interpolation accuracy order is higher than first-order.

Direct current solar electric heating elements can be powered by an array of photovoltaic panels. The direct current voltage can be low or high with proper electrocution protection. Insertable immersion heating elements can be placed into any existing, gas, propane or electric hot water tank, cooking pot or hot tub. Heating elements in air can also be used for heating ovens, range cook tops and sauna heaters. The output of the photovoltaic panel is interfaced to the electric heater element via either direct connection or using a load-matching controller which maximizes the power delivered to the heater under all sun conditions. The maximum heater temperature is regulated by a thermostat.

A gift transaction processing system/method allowing collection and management of financial and non-financial gifts from gift donors to gift recipients using a distributed communication network is disclosed. The gift donor interacts with a graphical user interface (GUI) client to donate a gift under control of a gifting computing server (GCS). The GCS receives gift donor information and assigns an identification token to the gift donor and associates this token with the received gift donor information. The GCS then sends the token and an HTML document identifying the gift to the client along with a donation application activator. The client receives this information and displays the HTML document at which time the donor selects the donation activator and the client informs the GCS to complete the gift transaction and provide a receipt to the donor via the client.

A heat exchanger which is adapted to an existing water tank to allow it to be heated or cooled using a hot or cold toxic or non-toxic liquid. Solar collectors, other heat sources and heat pumps can provide hot or cold liquids. To transfer this heat economically to an existing hot water tank requires a simple, efficient, heat exchanger, which can be easily adapted to the existing tank. The invention recited fills this need by simply screwing into the existing hot or cold water tank and allows heat or cold to be added or extracted via a simple fluid loop which is double wall isolated for toxic and non-toxic heat exchange fluids.

Delivering heat from modem high temperature solar collectors to hot water storage tanks is more effectively done using unpressurized when cold, self-pressurized on heat up, automatic air eliminating, higher temperature fluid loops. A pressurizing valve, an overflow reservoir and a vacuum relief valve are used. Non-toxic water/antifreeze mixtures are pressurized up to about two atmospheres resulting in a 265° Fahrenheit boiling point. Loss of circulation under full sun results in solar collector boiling under pressure. The steam generated in the solar collector is condensed in the pressurized liquid-to-air radiator, a steam heat pipe, and water is returned to the solar collector to keep it completely full of fluid and steam. A set of pressure-actuated air dampers on the solar collector can also be used to shed the excess solar collector heat.

A method and system for providing customer service evaluations to entities seeking testing of their employees' customer service skills. The method automatically records a mystery shopper's conversation with a targeted employee and attaches a corresponding voice file to a shopping report which can later be completed by the shopper. The mystery shopper first learns of a mystery shopping assignment and then calls a telephone recording system. The shopper is prompted to enter his or her user ID, a call code related to the shopping assignment, and the phone number of the target company. The telephone recording system then connects the shopper to the target company and automatically records the shopper's conversation with an employee of the company. Once the mystery shopper completes the assignment and hangs up, the recording is automatically converted to a voice file and transmitted to a web reporting system along with the call code. The web reporting system uses the call code to locate the shopping report corresponding to the assignment and then attaches the voice file to the shopping report. The mystery shopper may then access the web reporting system via the Internet or other communications network and complete the shopping report. The mystery shopper may also listen to the voice file while filling out the report to assist in its completion. Once the shopping report is completed by the mystery shopper and possibly edited by a supervisor of the mystery shopper, it is made available to the company that requested the evaluation.
