Patent number: 9083536Abstract: A circuit is for monitoring the powering of a remote device through a LAN without generating an extra biasing voltage higher than the DC power supply voltage. DC voltage used for supplying the remote device is applied to the LAN line while an AC voltage is applied to the line for monitoring whether the remote device is connected to the LAN line. The DC voltage is applied to a first or “high” terminal and the AC voltage is applied to the other or “low” terminal of the LAN line through a decoupling capacitor. This arrangement allows the supplying of the remote device with a large DC voltage compatible with a fully integrated AC signal generator, disconnection detector, and PSE controller, and enhances the reliability of the recognition of whether the powered device is connected to, or disconnected from, the LAN line.Type: GrantFiled: May 21, 2007Date of Patent: July 14, 2015Assignee: STMICROELECTRONICS S.R.L.Inventors: Riccardo Russo, Aldo Torazzina

Publication number: 20150194876Abstract: A power supply includes a power supply circuit and a power-on circuit controlling transitioning of the power supply circuit to a turned-on state. The power-on circuit includes a code driver, a controller coupled to the power supply circuit and code driver, and a transducer to detect a wireless control signal and generate an enable signal based thereupon. A transistor has a first conduction terminal coupled to the code driver, a second conduction terminal coupled to the controller, and a control terminal coupled to the transducer to receive the enable signal so the transistor switches based thereupon. The code driver detects a code embedded in the wireless control signal based upon switching of the transistor, and generates a power on signal for the controller based upon the code. The controller causes the power supply circuit to transition from the turned-off state to the turned-on state based upon the power on signal.Type: ApplicationFiled: March 23, 2015Publication date: July 9, 2015Applicant: STMicroelectronics S.r.l.Inventors: Roberto Larosa, Giulio Zoppi, Natale Aiello

Patent number: 9077873Abstract: Image defects in digital images are easily detectable by the human eye but may be difficult to detect in a computer-implemented fashion. In an embodiment of a digital-image-acquisition device, defects are removed on the CFA domain before color interpolation takes place. In order to allow cancellation of couplets of defective pixels, a two pass embodiment is presented. Such embodiment presents methods and systems that can remove both couplets and singlets without damaging the image. The system includes a ring corrector that detects a defect in the ring of pixels that surround a central pixel, a singlet corrector that detects and corrects the central pixel and removes a couplet if the ring corrector is activated, whereas if the ring corrector is switched off, the singlet corrector only removes singlets, and a peak-and-valley detector that avoids overcorrection by avoiding correcting signal peaks or valleys in case of spikes or drops in signal.Type: GrantFiled: December 20, 2012Date of Patent: July 7, 2015Assignee: STMICROELECTRONICS S.R.L.Inventors: Angelo Bosco, Arcangelo Ranieri Bruna, Davide Giacalone
