Publication number: 20120159020Abstract: There is a need to cause a delay to occur less frequently than the related art during processing of an input signal in need of relatively fast processing. In a semiconductor device, a conversion portion includes first channels and second channels and A/D converts a signal input to a selected channel. A signal input to the first channel requires faster processing than a signal input to the second channel. The conversion portion receives a scan conversion instruction from a central processing unit, sequentially selects the input channels in a specified selection order, and successively performs A/D conversion. In this case, the conversion portion notifies a peripheral circuit of completion of A/D conversion after completion of A/D conversion on signals input to the first channels and before completion of A/D conversion on input signals input to all input channels.Type: ApplicationFiled: December 20, 2011Publication date: June 21, 2012Applicant: RENESAS ELECTRONICS CORPORATIONInventors: Daijiro HARADA, Takashi UTSUMI

Active components which provide analog signals to the A/D converters are switched off to cause spikes in the analog signals/channels. The spikes are digitized by the A/D converters and sent to the host through a USB interface. The active components are switched on and off in a pattern corresponding to a message, such that the host can determine the message from the resulting spikes. If multiple active components and A/D converters are used, then multiple ‘bits’ can be transmitted simultaneously using the different channels.Type: ApplicationFiled: January 27, 2009Publication date: July 8, 2010Applicant: Sony Computer Entertainment Inc.Inventor: Xiaodong Mao

Publication number: 20100153597Abstract: The illustrative embodiments described herein provide a computer implemented method, apparatus, and computer program product for generating furtive glance cohorts. In an illustrative embodiment, video data of a monitored population is received and processed to form digital video data. The digital video data includes metadata describing glancing patterns associated with one or more subjects from the monitored population. The digital video is analyzed to identify a set of furtive glance patterns from the glancing patterns. One or more furtive glance attributes for the set of furtive glance cohorts are selected from the set of furtive glance patterns. Thereafter, the set of furtive glance cohorts is generated. The set of furtive glance cohorts have members selected from the monitored population and have at least one furtive glance attribute in common.Type: ApplicationFiled: December 15, 2008Publication date: June 17, 2010Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Robert Lee Angell, Robert R.

Publication number: 20100095031Abstract: A dongle module including a digital video differential signal input terminal, a keyboard control signal I/O terminal, a mouse control signal I/O terminal, a processing unit, a transforming unit, a synthesizer unit and a signal I/O terminal is provided. The digital video differential input terminal receives a digital video differential signal, which includes multiple differential data signals, a differential clock signal and multiple low-frequency signals. The processing unit processes the low-frequency signal, a keyboard control signal and a mouse control signal to obtain a digital hybrid data. The transforming unit transforms the digital hybrid data into a differential hybrid signal. The synthesizer unit receives and composes the differential clock signal and the differential hybrid signal into a differential synthesized signal. The signal I/O terminal receives and outputs the differential data signals and the differential synthesized signal.Type: ApplicationFiled: October 15, 2009Publication date: April 15, 2010Applicant: ATEN International Co., Ltd.Inventors: Fu-Chin Shen, Chia-Hsien Tang

Patent number: 7694027Abstract: Videoconferencing through an information handling system is supported with a display, camera and microphone that communicate with the information handling system through a single cable, such as a DisplayPort cable. Visual information is communicated from the information handling system to the display through a unidirectional main link and display control information is communicated between the information handling system and the display through a bidirectional auxiliary link. Peripheral information, such as digitized audio signals captured by the microphone and packetized video information capture by the camera, are communicated to the information handling system through the auxiliary link. Peripheral commands generated at the information handling system, such as camera control commands, are communicated from the information handling system to the peripheral through the auxiliary link.Type: GrantFiled: July 18, 2006Date of Patent: April 6, 2010Assignee: Dell Products L.P.Inventor: Bruce Montag

Patent number: 7685336Abstract: A keyboard-mouse-video (KVM) switch has a server interface, a client interface, a switch circuit and a digital video overlapping circuit. The server interface is connected to plural computers, and the client interface is connected to plural sets of manipulation and display devices. The switch circuit routes paths between the computers and the sets of manipulation and display device. The digital video overlapping circuit overlaps a digital video overlapping image onto a digital video signal received from one of the computers through the server interface. The overlapped digital video signal is then transmitted to one of the sets of manipulation and display device through the client interface.Type: GrantFiled: January 19, 2005Date of Patent: March 23, 2010Assignee: ATEN International Co., Ltd.Inventor: Li-Shan Chiang

Patent number: 7673081Abstract: In a method and system for data and signal transfer between different sub-units of a medically-related system, in particular a CT system, digitized signals and digital data are transmitted together on a transmission line by means of serial multiplexing. The digitized signals and the digital data are transferred combined into individual packets having a length that is so small that the adherence to a predetermined updating rate of the signals is achieved.

Patent number: RE41343Abstract: Monitoring a converter (1) includes detecting whether a value of an input variable (2) for the converter (1) assumes a first prescribed input reference value (41) and checking whether an output variable (3) from the converter (1) likewise assumes a corresponding, second prescribed output reference value (61). This means that the operation of the converter is tested only at occasional instants, specifically only using individual, prescribed values. The fact that only prescribed values (41, 61) are compared with instantaneous values of the input and output variables (2, 3) means that the invention can be implemented using very simple means. The method is particularly suitable for monitoring the operation of a converter (1) in a control or protective device for an electrical switchgear assembly. In this context, when a malfunction in the converter (1) is detected, all protective functions which are dependent on the converter (1) are preferably turned off.Type: GrantFiled: June 10, 2005Date of Patent: May 18, 2010Inventor: Guido Wenning
