  • Publication number: 20190246842
    Abstract: An economical blender with a removable, motor driven spindle assembly to perform blending, a motor driven elevator used to lift a cup with food or beverage up to the spindle assembly and a liquid reservoir which allows liquid to be inserted into the food or beverage during blending. The removable spindle assembly has a quick release coupler and a compression spring which connects the quick release coupler to a cup cover. Blending is accomplished by connecting a motor driven inner spindle drive shaft to a concentric outer spindle drive tube through cogged couplers. The outer spindle drive tube powers a blending tool and, like the blending tool, is removable with the spindle assembly for cleaning.

  • Publication number: 20180132663
    Abstract: An easily assembled blender with an internal frame holding a cupholder elevator assembly, a mix motor assembly, a food preparation chamber, a water heater assembly and a steamer assembly. The water heater and steamer assemblies are preferably on modular trays that slide into the internal frame. The water heater preferably also serves as a hot water reservoir and, to avoid overheating, has its heating coil located near its bottom. To resist scale deposits, polytetrafluoroethylene (PTFE) tubing is preferably used to transport steam from the steamer to the food preparation chamber. To expedite manufacture, a spring-biased idler assembly with a drive belt for the cupholder elevator assembly preferably snaps into a lower receiving port on the internal frame. Crisscrossing infrared light beams are preferably placed at the entrance of the food preparation chamber to detect whether the cup entering the chamber is the correct size and detect whether any foreign object is below the food preparation chamber.

  • Patent number: 9579615
    Abstract: A blender for home or commercial use that is rugged enough to blend frozen beverages, simple to use and safe. The blender includes an upper housing with a front housing door that covers the moving blending machinery. The blender also includes a cupholder receiving area which allows the user to safely insert a frozen food or beverage cup inside a cupholder for blending. After the start button is pressed, the cup and cupholder will be lifted together for blending in a balanced, linear motion by an elevator assembly. Dual lead screws or a dual belt drive are preferably used in the elevator assembly to achieve this balanced, linear motion. As the cupholder is lifted upward, a cover will be pressed over the top opening of the inserted cup to prevent spillage during blending. The elevator assembly continues to lift the cupholder upward until the rotating cutter blades of a spindle assembly cut through successive layers of the frozen food or beverage.

  • Patent number: 9420917
    Abstract: A method for blending food or beverages, preferably using a blender that is compact enough for home use, rugged enough to blend frozen beverages, simple to use and safe. The blender includes an upper housing, with a front housing door, that covers the moving blending machinery. The blender also includes a cupholder receiving area which allows the user to safely insert a frozen beverage cup inside a cupholder for blending. After the start button is pressed, a cupholder lip will be grasped by the clamping jaw of an elevator assembly to lift the cupholder up. As the cupholder is lifted upward, a cover will be pressed over the top opening of the inserted cup to prevent spillage during blending. The elevator assembly will then continue to lift the cupholder upward until the rotating cutter blades of a spindle assembly cut through successive layers of the frozen beverage.

  • Patent number: 7959869
    Abstract: An air-transporter conditioner device includes a housing defining an inlet and an outlet. An electro-kinetic system is disposed in the housing to create an airflow moving from the inlet to the outlet. A timer measures a time period corresponding to the electro-kinetic system and causes an indicator light to illuminate when the measured period reaches a threshold. An arc sensing circuit detects arcing between the first and second electrode arrays of the electro-kinetic system. The electro-kinetic system is turned off in response to arcing being detected by the arc sensing circuit. An indicator light can also specify that arcing has been detected.

  • Patent number: 7801645
    Abstract: A robot uses an infrared sensor including an infrared light source which produces pulses of infrared light. Optics focus reflections of the infrared light pulses from different portions of the environment of the robot to different detectors in a 2D array of detectors. The detectors produce an indication of the distance to the closest object in an associated portion of the environment. The robot can use the indications to determine features in the environment. The robot can be controlled to avoid these features.

  • Patent number: 7767165
    Abstract: A personal electro-kinetic electro-static air conditioner includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone, and includes a water retaining element to increase humidity of the output air flow. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first electrode array includes first and second pointed electrodes, and the second electrode array includes annular-like electrodes having a central opening coaxial with the associated pointed electrode. The surface of the annular-like electrodes is smooth and continuous through the opening and into a collar region through which the air flows. A water retaining member is disposed surrounding the output airflow to increase humidity of the output air, which is substantially cleansed of particulate matter, and contains safe amounts of ozone.

  • Patent number: RE41812
    Abstract: An electro-kinetic electro-static air conditioner includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first array comprises one or more wire electrodes spaced staggeringly apart from a second array comprising hollow ā€œUā€-shaped electrodes. Preferably a ratio between effective area of an electrode in the second array compared to effective area of an electrode in the first array exceeds about 15:1 and preferably is about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. A bias electrode, electrically coupled to the second array electrodes, affects net polarity of ions generated. The outflow of ionized air and ozone is thus conditioned.
