20090072809 | Method for detection of the presence of a load and drive circuit - Methods and apparatuses for detection of a presence of a load. A method may include, for example, applying and subsequently removing a supply voltage across the pair of nodes, comparing an electrical potential at one of the pair of nodes at a time after the supply voltage is removed with a reference value, and generating a signal having a value that depends upon an outcome of the comparison. | 03-19-2009 |
20140009166 | Monitoring Circuit with a Signature Watchdog - A method can be used for monitoring a processing circuit. The processing circuit generates a response to a request and the response is compared with an expected response. A pass pulse is generated when the response matches the expected response. The causing, comparing and generating steps are repeated a number of times A frequency at which pass pulses occur is evaluated. | 01-09-2014 |
20140013150 | Monitoring Circuit with a Window Watchdog - A method of monitoring a processing circuit is disclosed. The processing circuit is operable, in a normal operation mode, to generate a sequence of trigger commands, with at least one trigger command of the sequence of trigger commands including time information. At least one window sequence with a closed window period and an open window period is generated such that the duration of the closed window period and/or the open window period is defined, at least in part, by the time information. It is detected if one trigger command is received within the open window period of the at least one sequence. | 01-09-2014 |
20140268442 | CIRCUIT ARRANGEMENT AND METHOD FOR EVALUATING A SIGNAL - Circuit arrangement including an interface, a protection circuit and a measurement circuit. The interface is configured to receive a signal. The protection circuit is coupled to the interface. The protection circuit is configured to limit a voltage provided by the interface to a protection voltage. The measurement circuit is coupled to the protection circuit and configured to provide at least one of a signal of a first measurement type and a signal of a second measurement type if a voltage provided by the interface is higher than the protection voltage and configured to provide a signal of a second measurement type if the voltage provided by the interface is lower than the protection voltage. | 09-18-2014 |
