Abstract: A charge-injection cell-based temperature sensor (1) is provided. The temperature sensor (1) comprises one or more charge-injection cells (3, 9). The temperature sensor (1) is configured to allow charge to be transferred from one or more source capacitors (Cs,n, Cs,p) to one or more output capacitors (Cout,n, Cout,p) once transistors (M1, M2, M3, M4) of the charge-injection cells are enabled to allow current to flow through them. The temperature sensor (1) further comprises a temperature sensing unit (7) configured to determine one or more charge-injection cell output voltage values to thereby derive a temperature value from the one or more first charge-injection cell output voltage values.

Abstract: To improve the temperature measurement accuracy in a circuit that measures temperature by using an operational amplifier.
An operational amplifier outputs an output voltage corresponding to a difference between terminal voltages of a pair of input terminals. A resistor has one end connected to one of the pair of input terminals. A resistor-side rectification element is connected to another end of the resistor. A terminal-side rectification element is connected to the other one of the pair of input terminals. A switch connects an additional rectification element in parallel with either the resistor-side rectification element or the terminal-side rectification element. A current output section outputs a current corresponding to the output voltage. A difference acquisition section acquires, as temperature data, a difference between a signal corresponding to the current provided when the additional rectification element is not connected to the resistor-side rectification element or the terminal-side rectification element and a signal corresponding to the current provided when the additional rectification element is connected to the resistor-side rectification element or the terminal-side rectification element.-

Abstract: Certain aspects and features provide generation or simulation of sensory data that would otherwise come from Internet-of-things (IoT) sensors in reproducible and controllable way. Thus, the response of a system to very large numbers of sensors can be tested without acquiring and deploying a very large number of sensors for test and development purposes. In some examples, a processing device coupled to a network interface identifies a stored function of time describing a locally sensed property for a simulated sensor. The locally sensed property corresponds to at least one event taking place in a virtual environment. The processing device can determine values of an input variable produced by the stored function of time. The values can be wrapped in a communication protocol to produce messages that are transmitted over the network interface.

Abstract: A converter of a variable frequency drive (VFD) is operated in a ramp-up mode to produce an AC output voltage for accelerating a motor. A loading of the converter is determined concurrent with the ramp-up mode. Transfer of the motor to a bypassed mode is conditioned on whether the determined loading in the ramp-up mode meets a criterion. In some embodiments, conditioning transfer to the bypassed mode comprises foregoing transition to the bypassed mode based on a comparison of the determined loading to an underloading threshold.
