Abstract: Present invention teaches a portable teeth-cleaning device where a flexible water tank is stored inside the main body of the device; when water is being sent into the flexible water tank, getting it ready for use, the tank will expand in volume and come out of the main body. A pump is used to perform the water intake function and the water squirt-out function, via guide channels, with controlling means to control the mechanism of either 3 valves or 2 switch valves to effectuate the intended functions.

Abstract: Disclosed is a system and method for automated serving of one or more items. According to the system and method, a central controller may initially capture order details associated to an order placed by a user for serving an item. A control system may trigger one or more item producing components along with a robot unit to collectively process the order in order to produce the item based upon the order details. Further, the control system may determine a hold zone position available from multiple hold zone positions in a predefined hold zone for holding the item corresponding to the order. Further, the robot unit may move the item produced corresponding to the order in the said hold zone position of the hold zone. The robot unit may dispense the item from the said hold zone position into a delivery bay engine thereby serving the item to the user.

Abstract: An anatomical shaped oxygen face mask with ports allows medical procedures to take place while the mask remains affixed to patient's face covering both mouth and nose. The mask is specially designed to allow the patient to ventilate spontaneously while at the same time allowing access for instruments by means of ports located at the front of the mask. One port may be used for procedures while another port can be used for suctioning of secretion and blood or for providing oxygen.

Abstract: A method for profiling information technology (IT) service contract risks and generating contract prices includes analyzing historical IT service contract risk data to create a set of IT service contract risk profiles, where the historical IT service contract risk data includes contract risks and percent gross profit associated with a historical set of contracts, where each IT service contract risk profile is a probability distribution function of achieving a percent gross profit associated with a subset of contracts corresponding to particular set of contract risk values, and creating a mapping between a particular IT service contract risk profile and a new IT service contract associated with the set of contract risk values for the IT service contract risk profile to determine an optimum price for the new IT service contract.

One port may be used for procedures while an other port can be used for suctioning of secretion and blood.

Abstract: A power generation diode module adapted in a roof tile; the module containing a substrate, multiple GaAs chips being disposed on the substrate, each GaAs chip is disposed with a package; sun light being irradiated into those packages where to be refracted, converged inter the GaAs chip to convert light source into electric power before being transmitted from the substrate to a power consumption object in a house built up with multiple roof tiles.

Abstract: A transportation device adapted with a solar photo module includes a main frame, at least two side frames disposed on both sides of the main frame; a locating gap to accommodate the solar photo module is disposed to each side frame; and the solar photo module absorbs solar energy to convert it into electric power serving auxiliary power for consumption by the transportation device.
