Abstract: The invention is an apparatus and method of varying power output and decrease noise generation of spa pumps by powering them with a variable frequency power device, digital signals capable of controlling cascaded pumps using ganged controls, and to decrease safety concerns of spas using an integrated water level and motion detectors.

Abstract: A multi-sensing device is provided which includes a first sensor for sensing a temperature of the fluid flowing through the filter element, a second sensor for sensing a pressure generated by the fluid flowing through the filter element; and an indicator for indicating a condition of the filter system, and a microcontroller operatively coupled to the first and second sensors.

Abstract: A fluid displacing apparatus, system, and method is provided. The apparatus includes a motor having a first shaft, the motor for rotating the first shaft; a first magnetic element coupled to the first shaft such that rotation of the first shaft causes rotation of the first magnetic element; a second magnetic element coupled to a second shaft, and magnetically coupled to the first magnetic element such that rotation of the first magnetic element causes rotation of the second magnetic element; an input section for receiving a fluid; an output section for outputting the fluid; a channel having first and second openings; and an impeller coupled to the second magnetic element such that rotation of the second magnetic element causes rotation of the impeller, thereby the fluid flows in the input section and out the output section. The flow of the fluid across the second opening of the channel encourages another fluid to flow in the first opening, through the channel, and out the second opening.

Abstract: The high speed intelligent cable provided herein is multifunctional, lightweight, flexible and re-configurable. The cable assembly includes a low profile ribbon cable of multiple conductors. Built-in health indicators provide user assessment of, for example, connectivity. Active electronics and embedded intelligent firmware provide various functions, to include built-in test performance capability. Ready cable reconfiguration for system integration, or for other needs, is facilitated by logic and switching circuitry. Still further, built-in automatic multi-functional cable testing may include automatic reconfiguration. Testing and reconfiguration can be remotely activated. The cable described herein can reduce time and manhours needed for testing, installation, and maintenance. The lightweight multi-functional cable makes a positive contribution to the function/mass payload ratio in complex and mass-sensitive applications.

Abstract: A flexible high speed micro-cable and method of making the same are described. The parallel conductors incorporated in the present cable contribute to the flat cross section of the cable, while the unique combination of materials yield a flexible cable with a low profile. The data transfer rate and transmission losses of a cable, as provided herein, exceed High Speed Universal Serial Bus (USB) 2.0 specifications and data transmission is achieved from USB devices. The lower volume and mass of the cable make it ideal for applications needing low mass payload, such as satellites. The flexible nature of the cable allow it to readily conform to a desired structure for mounting or routing. A flexible high speed micro-cable is fabricated from a unique combination of materials and fabrication can be readily automated.
