Abstract: A method and apparatus for measuring a duration of an event using two time-varying waveforms, each waveform having characteristics such that the waveforms intersect at an intersecting point. The duration of the event can be determined based on the characteristics and a value of the intersecting point of the waveforms. The characteristics of the waveforms can be the gradient or the initial value of the waveforms.

Abstract: A fan includes an impeller and an inner rotor motor. The inner rotor motor connects to the impeller and drives it to rotate. The inner rotor motor includes a bushing, a shaft, a magnetic conducting shell, a magnetic element and a stator. The shaft passes through the bushing and is coupled to the impeller. The magnetic conducting shell is coupled to the shaft and telescoped to the bushing. The magnetic element is disposed around outside of the magnetic conducting shell. The stator is disposed around outside of the magnetic element.

Abstract: A serial fan is provided and includes a first fan and a second fan. The first fan includes a first frame, and the second fan includes a second frame. The first frame and the second frame form a frame set. The first frame has at least one first locking portion. The second frame has at least one second locking portion disposed corresponding to the first locking portion. When the first fan and the second fan are assembled, the first locking portion inserts in the second locking portion along a rotational direction so that the first frame and the second frame are connected in series.

Abstract: A switching pre-regulator for a bulk capacitor filter followed by a series pass regulator has a switching element controller that relies upon a large desirable leakage inductance in a main secondary winding of a power transformer acting as a swinging choke input to the bulk capacitive filter. This desirable leakage inductance limits inrush current and supplies some filtering. However, the effective value of the swinging choke is a function of load conditions, and introduces a varying phase shift that would potentially disturb the zero crossing detection used in properly activating the switching element.

Abstract: A fan includes a frame, a motor base, an impeller, an airflow guiding component, and at least one outwardly expanded part. The motor base is disposed in the frame, and the impeller is disposed on the motor base. The outwardly expanded part, connected with the frame, is disposed at an airflow inlet or an airflow outlet, for increasing areas of intake airflow or discharge airflow. One end of the airflow guiding component is connected with the motor base, and the other end is connected with an inner surface of the frame, instead of being connected with the outwardly expanded part, to prevent the fan from forming blocks on the frame during molding process.

Abstract: Zero crossings for a non-symmetrical VIN may be determined by first amplifying and clipping VIN to create a non-symmetrical square wave whose zero crossings are those of VIN. A selected polarity edge of the non-symmetrical square wave may be taken as a 0° indicator and is used to create a fundamental sawtooth ramp of the same frequency and in phase with VIN. The fundamental sawtooth ramp starts at zero volts, linearly ramps to some peak and is AC coupled to a comparator whose other input is zero volts. That creates a square wave that is symmetrical as to its half-cycles, and whose every other edge is synchronous with the start of the fundamental sawtooth ramp, and whose intervening edges occur in the middle of the ramp. The intervening edge is detected and taken as a 180° indicator.

Abstract: A fan includes a frame, an impeller and a motor. The impeller is accommodated in the frame. The motor connects and drives the impeller to rotate, and includes a rotor structure and a stator structure. The dimension Y of the frame and the diameter X of the stator structure meet the equation of Y=CXn? wherein C is a constant, and n is a variable number. A selecting method for motor size of the fan is also disclosed.

Abstract: A fan includes a housing, an impeller and a motor. The housing has a main body, a motor base and at least one supporting member disposed between the main body and the motor base. The impeller is disposed on the motor base and has a hub and a plurality of blades disposed around the hub. The motor is connected to the impeller for driving the impeller to rotate. Each of the blades is connected to the hub at a predetermined angle ranging from 22.5 degrees to 36 degrees.

Abstract: The present invention provides a method for determining cellular response to stimuli. The cells to be tested, for example, may be contained in a section of taste-bud containing lingual epithelium.

Abstract: A method and apparatus for presenting and modifying data from a set of tables in a database is provided. A view that is defined is based on a set of one or more tables that may include relational tables or object tables. The view defines a presentation of data from the one or more tables as a set of objects that reside in the database. Data is read from the one or more rows of the tables based on the view, and is presented as a set of objects that reside in the database. An object id that is based on data from the one or more rows is generated and associated with each object presented. The view may specify which columns from the one or more tables contain values used to generate the object ids. A trigger may associated with the view. The set of objects presented may be presented as objects having an attribute that is a column object. Column objects include user specified object types, collection objects (e.g. nested tables and variable arrays), or references to objects.

Abstract: Methods to reduce the astringency of substances such as foods and beverages are provided. Compositions exhibiting reduced astringency are also provided.

Abstract: A first set of instructions and incoming data are provided to a first processing unit of a data driven processor, to operate upon the incoming data. The first processing unit, in response to recognizing that the first set of instructions will require either reading from or writing to external memory, sets up a logical channel between a second processing unit of the processor and the external memory, to transfer additional data between the external memory and the second processing unit. This capability may be implemented by the addition of a control port, separate from data ports, to the first processing unit, where the control port allows the first processing unit to write addressing information and mode information (including the location of the additional data) for reading or writing the additional data via a memory access unit data channel of the processor.
