Abstract: A sub-bandgap reference voltage generator includes a reference current generator generating a reference current (proportional to absolute temperature), a voltage generator generating an input voltage (proportional to absolute temperature) from the reference current, and a differential amplifier. The differential amplifier is biased by the reference current and has an input receiving the input voltage and a resistor generating a voltage proportional to absolute temperature summed with the input voltage to produce a temperature insensitive output reference voltage. The reference current generator may generate the reference current as a function of a difference between bias voltages of first and second transistors.

Abstract: Method and system for determining calving information about a moment at which a cow is going to calve, a period in which a cow is going to calve or the moment at which the cow has calved. The system comprises a sensor and a signal processing unit which is configured to process signals obtained with the sensor. With the sensor a heartbeat of the cow is measured so that the signals obtained with the sensor comprise information about the measured heartbeat of the animal. With the signal processing unit an increased heartbeat is recognized according to a predetermined criterion on the basis of signals obtained with the sensor. If the increased heartbeat is recognized with the signal processing unit, the signal processing unit generates an alarm signal which comprises the calving information.

Abstract: The invention relates to a method for the detection of a target nucleotide sequence in a sample based on an oligonucleotide ligation assay wherein probes are used that contain (a combination of) sequence-based identifiers that can identify the sample and the target sequence (i.e. locus and/or allele combination) wherein after the ligation step, the ligated probes, or after amplification, the amplified ligated probes, are restricted using restriction enzymes to cut of part of the probes and continue with those parts (identifiers and target sequence) that contain the relevant information in the sequencing step.

Abstract: A circuit includes a frequency detector generating a comparison signal as a function of a comparison between a reference signal and a feedback signal. An oscillator generates an output signal as a function of the comparison signal. A frequency divider, in operation, divides the output signal by a division value to produce the feedback signal as having a frequency that is a multiple of a frequency of the reference signal. A frequency counter circuit measures the frequency of the reference signal and generates a count signal based thereupon. A control circuit adjusts the division value used by the frequency divider, in operation, based upon the count signal.

Abstract: A wordline coupled to a memory cell is selected in connection with performing a read/write operation at the memory cell. A wordline signal is asserted on the selected wordline. The assertion of the wordline signal has a leading edge and a trailing edge and, between the leading edge and trailing edge, a series of wordline underdrive pulses. Each wordline underdrive pulse causes a wordline voltage to fall from a first voltage level to a second voltage level and then rise from the second voltage level to the first voltage level. The first and second voltage levels are both greater than a ground voltage of the memory cell.

Abstract: Embodiments of present invention are directed to document authentication based on video captures. Instructions may be generated to guide a remotely situated customer through an authentication process in which the customer presents a document (e.g., a driver license, passport, or payment card) to a video capture element of a personal computing device (e.g., a smart phone or tablet computer) in a specified manner so that identifiable feature(s) of that document can be captured in a video file. The video file may then be uploaded to a central server for further processing or archiving. The instructions that guide the customer through the document authentication steps may be either generated locally on the personal computing device via a mobile application or delivered from a remote computer via an Internet browser. With this technique, a banking customer need not physically visit a bank to authenticate certain documents.
