Various embodiments of an electric motor and electronic control for an electric motor are disclosed. An exemplary electric motor comprises a single-phase brushless permanent magnet electric motor. In exemplary embodiments, the electronic motor control is configured to commutate an electric motor at a frequency other than line frequency, perform pulse width modulation, and drive the electric motor with a drive waveform that approximates the counter-electromotive force of the motor.

The present invention relates to a subscription modeling system and methodology. A query processor receives subscription query and subscriber information and transforms the query and subscriber information into data. An index component propagates at least one database with the transformed data; and a matching component that associates the transformed data with event data to generate a database of notification data that can be delivered to subscribers. The invention provides for abstracting subscription and subscriber information (as well as event information if desired) to high-level classes (e.g., data fields)—thus the invention provides for modeling such notification related information as data. Subscription applications can thus be developed at high levels wherein complex subscription queries and subscriber information can be defined as data fields for example. Databases in accordance with the data fields can be propagated with subscription / subscriber specific information. The present invention takes advantages of the processing power associated with database engines (e.g., SQL server) to generate notifications via performing a join operation on the databases (e.g., subscription database(s), subscriber database(s) and event database(s)). Accordingly, notifications are generated en masse as compared to per subscription per subscriber. Thus the present invention provides for a highly scalable and efficient notification system.

An apparatus for processing an input audio signal relies on a cascade of filterbanks, the cascade having a synthesis filterbank for synthesizing an audio intermediate signal from the input audio signal, the input audio signal being represented by a plurality of first subband signals generated by an analysis filterbank, wherein a number of filterbank channels of the synthesis filterbank is smaller than a number of channels of the analysis filterbank. The apparatus furthermore has a further analysis filterbank for generating a plurality of second subband signals from the audio intermediate signal, wherein the further analysis filterbank has a number of channels being different from the number of channels of the synthesis filterbank, so that a sampling rate of a subband signal of the plurality of second subband signals is different from a sampling rate of a first subband signal of the plurality of first subband signals.

New methods and systems for manufacturing a three-dimensional form, comprising steps of providing a plurality of particulates; contacting the particulates with an activation agent; contacting particulates having the activation agent with a binder material that is activatable by the activation agent; at least partially hardening the binder for forming a layer of the three-dimensional form; and repeating these steps to form the remainder of the three-dimensional form. Following sequential application of all required layers and binder material to make the form, the unbound particles are appropriately removed (and optionally re-used), to result in the desired three-dimensional form. The invention also contemplates a novel method for preparing a form, where unbound particulates free of binder material are re-claimed.

A coder codes an information signal. A rate controller controls a coding rate of the coder in accordance with complexity of the information signal. The rate controller controls a coding amount per unit time in the coding process so that an average value of the coding amount can be approximate to an average rate. The coded data is temporarily memorized in a temporary memory unit and processed by an information processing unit such as a recorder and a transmitter. The information processing unit measures an information processing rate in processing the information. The rate controller adjusts the average rate so that the average rate is lower than the information processing rate measured by the information processing unit, or the rate controller compares a threshold value of a used amount of the temporary memory unit which is previously set and an actually used amount of the temporary memory unit and reduces the average rate when the used amount exceeds the threshold value. Thereby, the rate control can be properly executed while the coding amount in accordance with the complexity of the information signal is allocated.

The invention discloses a management method and a device of operation systems in an embedded system, which relate to the field of mobile communication and solve the problems of larger performance loss and higher product complexity caused when a plurality of operation systems run on a single CPU in the prior art. The embedded system in the embodiment comprises at least two operation systems. The method comprises the following steps of: receiving an interrupt instruction; storing the states of the operation systems which run currently; and switching the operation systems which run currently to target operation systems corresponding to the interrupt instruction. The method is mainly applied to the field of the mobile communication.
