Abstract: In accordance with an embodiment, a video flow transmission method includes: the generating, by an image sensor, a video flow comprising first and second images; hashing, by the image sensor, a portion of the first image based on a first hashing configuration to generate a first hash value, the first hashing configuration defining first positions of pixels to be hashed; hashing, by the image sensor, a portion of the second image based on a second hashing configuration to generate a second hash value, the second hashing configuration being different from the first configuration and defining second positions of pixels to be hashed; and transmitting, by the image sensor, the first and second images, and the first and second hash values, to a second device.

Abstract: In order to protect a trading party from predatory trading strategies employed by some market participants, especially during certain periods when quotes for a particular security are experiencing rapid changes or transitions, embodiments of the present invention facilitate and support various new type of trading orders whose booking and execution behaviors are dynamically varied in response to environmental market conditions and/or predefined rules. For example, the orders may be allowed to trade at more aggressive price levels if the market is relatively stable, and the orders can only trade at less aggressive price levels or be automatically suspended or even cancelled when the market is unstable.

Abstract: Method and system for motor oscillatory state detection. According to various embodiments, the present invention presents a method for determining whether a motor is in an oscillatory state. The method includes powering up a motor for a period of time and then monitoring the movement of the motor during a period after the power if turned off. Based on the movement of the motor and/or impeller during a time period after the power is turned off, whether the motor is in an oscillatory state is determined. The method also includes initiating a process for handle error if the motor is in the oscillation state.

Abstract: The invention relates to a frequency converter designed for supplying an output signal having a radio frequency FR equal to the difference between the frequency FLO of a signal OS originating from an oscillator VCO and the frequency FI of an input signal IS. The frequency converter has two quadratic modules QM1 and QM2 for separating the signal originating from the-oscillator OS and the input signal IS into two components (LO1, LO2) and (FI1, FI2) in phase quadrature, two mixers MX1, and MX2 for multiplying the components thus obtained two-by-two, and combination means COMB for recombining the output signals RS1 and RS2 of the mixers MX1 and MX2. The frequency converter operates internally a good rejection of the image frequency while providing a good performance as regards noise and gain and an improved linearity as compared with known converters. Thus, frequency shifting before transmission in a wireless telephone may be accomplished.
