Abstract: A system and method for operating a ventilator to compensate for external gas flow reaching a patient from an external device, such as a nebulizer. A control unit of the ventilator monitors the gas flow rate from the ventilator and compares the gas flow rate from the ventilator to an expired gas flow rate from the patient. The difference between the inspired flow rate and the expired flow rate is due to the external device. The control unit modifies the operation of the ventilator to compensate for the external gas flow rate such that the flow of gas reaching the patient is maintained at a desired level.

Abstract: A method for adaptive load control by an electronic device is described. The method includes determining a wiring mode. The method also includes determining a frequency of a power source. The method further includes capturing a voltage waveform. The method additionally includes capturing a current waveform. The method also includes determining a load type of a load based on the voltage waveform and the current waveform. The method further includes determining a power factor based on the voltage waveform, the current waveform and the wiring mode. The method additionally includes operating the load based on the load type, the power factor and the frequency.

Abstract: A beverage holder apparatus includes a chip unit attached to a beverage holder and adapted to communicate with a chip unit reader to perform a payment transaction to purchase the beverage. The chip unit stores an account identifier associated with a financial account, and transmits the stored account identifier to the chip unit reader to perform the payment transaction.

Abstract: Methods and systems for configuration data management are disclosed. In one embodiment, a configuration management system may be configured to store a product operational control file for controlling a product based on configuration data. The configuration management system may define a plurality of orderable items and relationships between the orderable items and the configuration data. The configuration management system may receive an order for the product including a configuration requirement. The configuration requirement may include one or more of the orderable items. The configuration management system may then load the product operational control file and the configuration data onto the ordered product according to the defined relationship between the orderable item and the configuration data, and the configuration requirement of the ordered product.

Abstract: Embodiments of the present invention are directed to a method and system for detecting foreign matter in a container, and in particular to the detection of foreign matter during bottle processing operations. The detection system may include an optically clear container support for supporting the container and a light source for illuminating the container. The container may additionally include an imaging device disposed on an opposite side of the optically clear support from the container, wherein the imaging device captures an image of the illuminated container and container contents through the optically clear support in order to detect foreign matter in the container contents.

Abstract: A visor or cap brim is disclosed that prevents the pressure of the wind from blowing the cap off of the user's head. The visor portion is a generally planar surface that is held out away from the front of the cap portion that sits on the user's head. This creates a single large passage between the visor/bill and the cap and the visor/bill is held at such an angle that it acts a “spoiler” to press the hat down more firmly on the user's head in a high wind while at the same time shading the eyes and forehead from the sun. The visor portion of the cap is removably attached to a semi-rigid headband that encircles the base of the main body of the cap. This attachment is accomplished by a plastic “rivet” type arrangement connected at the terminal ends of a pair of arms attached to the novel visor portion. The visor portion includes a wind or air dam along its upper edge to increase stability and is also slidable up and down the arms.

Abstract: A portable pool cleaning system for the remote cleaning of a swimming pool including a housing and a base. A motor is connected to the housing and is attached to a high pressure pump wherein the pump includes both intake and ports. The first tubing is connected to the intake port and the opposite end is inserted into the swimming pool for the transportation of water from the swimming pool to the pump. A second tubing is connected to an output port of the high pressure pump with the opposite end of the second tubing placed into the swimming pool and attached to a self-propelled cleaning device. The self-propelled cleaning device uses a high pressure water stream as a scrubbing function. The motor is connected to a timer which is connected to a power source. The timer initiates the activation and deactivation of the motor and the self-propelled cleaning device. A means for attaching the base and portable pool cleaning system to the periphery of the swimming pool is also included.

Abstract: A controller for an electronically commutated electrical machine receives a feedback signal indicative of a parameter which it is desired to minimize, e.g. torque ripple, current, voltage, vibration or acoustic noise. The controller computes the amplitude and phase of a set of harmonics in the parameter and sequentially injects harmonics of the correct amplitude and phase to minimize the parameter. An optimizing routine iterates through the set of harmonics to further reduce the parameter.

Abstract: A mounting assembly is used to mount a liquid crystal display (LCD) to a printed circuit board. The mounting assembly includes a display support which is mounted to the printed circuit board and supports the display in spaced relationship to the printed circuit board. A connector with integral spring contacts snaps into an opening into the display support to electrically connect the contacts on the LCD to the contacts on the printed circuit board. The connector extends over a top surface of the LCD display and functions as a mechanical retention element.

Abstract: An apparatus and method for starting a single-phase variable reluctance motor defined by a stator having one or more pairs of projecting poles defining a principal axis and a rotor mounted on a rotatable shaft co-axial with the principal axis of the stator is provided. The apparatus includes a device for preventing the rotor from being halted in a position of zero-developed torque thereby enabling reliable starting of the motor. The device includes a vane defined by a ferromagnetic disk having alternating mark regions and space regions which is mounted to the rotatable shaft and may form part of a rotor position transducer. A permanent magnet is positioned so as to move the vane into a position at which starting torque of the desired direction will be developed when the motor is energized. A further embodiment combines the magnet with a Hall-effect sensor so that, in conjunction with the vane, a rotor position transducer is formed.
