Abstract: A circuit for detection of an HDMI source device to an HDMI sink device through an HDMI sink connector without regard for the activity state of the HDMI source device has a pull-up resistor having first and second terminals with the first terminal coupled to a DC power source. A switching device is coupled between the pull-up resistor's second terminal and ground at a circuit node. The switching device is switched on to couple the circuit node to ground when power is applied to a control terminal thereof from the HDMI sink connector power pin, and being switched off otherwise. The circuit node is coupled to a DDC/CEC GROUND pin of the HDMI sink connector. The circuit node is readable as a binary signal to indicate the presence of a source device to the HDMI sink connector, wherein the node exhibits a logic low signal when either the node is grounded by the DDC/CEC GROUND pin connection to a source device or when the switching device is switched on.

Abstract: The invention provides a compound of formula (I) or a salt or solvate thereof: wherein R1, n, X, Y and Z are as defined in the specification, and uses of such compounds. The compounds inhibit GlyT1 transporters and are useful in the treatment of certain neurological and neuropsychiatric disorders, including schizophrenia.

Abstract: A system and method for authenticating records. Certification information may be encoded in graphical form. This graphical form, or design, may be referred to as an “Indicia.” The record at issue may be printed out by a computer or stored electronically and bear on it an indicia that relates to the authenticity of the document. The indicia (and record) may then be scanned and interpreted by the computer to authenticate the record.

Abstract: An electrical power generator for outputting on-site electrical power comprises an engine; an alternator operatively coupled to the engine; a controller, operatively coupled to the engine and alternator for controlling at least one operational parameter relating to the engine or alternator, and a modem operatively coupled to the controller for receiving data from a remote source, the received data then being processed by the controller to control the operation parameter.
