摘要： This disclosure is directed to methods, computer program products, and systems for calibrating one or more remote sensing devices in an environment. The disclosed technology relates to a calibration device configured to determine measurement data within an environment. The calibration device may transmit the measurement values, or other calibration data items, to a remote sensing device via a wireless link while the remote sensing device stays with a structure in which the remote sensing device is commissioned to operate. In response to receiving the calibration data items, the remote sensing device may adjust one or more settings of the remote sensing device in order to satisfy a calibration threshold.

摘要： Disclosed is a sensor with compensation circuit for compensating offset by use of a switching circuit. The sensor has two operation modes for generating two output voltages, respectively. Offset is compensated by adding the two output voltages, and magnitude of the offset is calculated by subtracting the two output voltages. A noise threshold is set for checking if the circuit is affected by interference. When the circuit is affected by interference, the adding result of the two output voltages will be larger than the noise threshold, the output data will be hold and not updated, then a reminding signal will be issued to show that the circuit is affected by interference, and the output data flickers on a display unit when the adding result of the two output voltages is larger than the noise threshold for showing the circuit is affected by interference.

摘要： The present invention includes a body case having a biological sample sensor mounting portion on one end side, a temperature sensor (A) provided on the one end side inside the body case, a measurement portion connected to the biological sample sensor mounting portion, and a control portion connected to the measurement portion. A temperature sensor (B) is provided on one other end side inside the body case, and when measurement is performed by the measurement portion, temperature change amounts in the two end portions are compared using the temperature sensors (A) and (B). Furthermore, a measurement value obtained by the measurement portion is corrected using temperature information from either one of the temperature sensors (A) or (B) that is provided in the end portion on the side where the temperature change is smaller.

摘要： An apparatus and method is presented for network video management and recording of video signals and video analytics generated by a network of IP-enabled cameras. A set of IP cameras are connected in a LAN to a network video recorder further connected by LAN or WAN to a set of client stations. The client station operates a hybrid program including a web-browser and a native application operating on a computer. The network video recorder operates a media recorder to store video streams from the IP cameras into a media database and further operates a relational database for storing camera configuration data, device drivers, event information and alarms. The network video recorder includes a zero configuration networking discovery service for automatically detecting and downloading default configurations to the cameras. Client stations can stream video directly from IP cameras, receive recorded video streams and query the relational database for cameras and events.

摘要： An angle detecting apparatus is obtained. The angle detecting apparatus is capable of correcting an electrical angle frequency component of an angle signal contained angle signal. An angle detecting apparatus computes an angle signal of a rotary machine from a sine signal and a cosine signal obtained from the angle signal. Offset correction values for the sine signal and the cosine signal are computed from the angle signal. The computed offset correction value for the sine signal is added to the sine signal to correct the sine signal, and the computed offset correction value for the cosine signal is added to the cosine signal to correct the cosine signal.

摘要： A linearity compensation circuit is disclosed for improving the linearity of a sensing signal. The linearity compensation circuit may include a compensator that is capable of receiving a sensing signal from a sensor and generating a compensation signal based on the sensing signal. The linearity compensation circuit may also include an output circuit that is capable of combining the compensation signal and the sensing signal to generate a compensated signal that exhibits an improved linearity. Also disclosed is a sensing apparatus which includes a sensor and the linearity compensation circuit. The sensing apparatus may thus be able to generate a sensing signal that is linear over a wider dynamic range.

摘要： A detection circuit includes a charge amplifier, a calculation unit, and first and second paths. The charge amplifier converts the amount of electric charge generated by a sensor element into a voltage. The first path and the second path each connect the charge amplifier and the calculation unit. The amplification factor of the first path is higher than the amplification factor of the second path. When a voltage output from the first path is lower than a threshold voltage, the calculation unit detects a pressing force by using the output voltage. When the output voltage is equal to or higher than the threshold voltage, the calculation unit detects a pressing force by using a voltage output through the second path.

摘要： A MEMS system includes a proof mass, an anchor, an amplifier, first and second sense elements and their corresponding feedback elements. The proof mass moves responsive to a stimulus. The anchor coupled to the proof mass via a spring. The amplifier receives a proof mass signal from the proof mass and amplifies the signal to generate an output signal. The first sense element is connected between the proof mass and a first input signal and the second sense element is connected between the proof mass and a second input signal. The second input signal has a polarity opposite to the first input signal. The first feedback element is connected between the proof mass and the output signal and its charges change responsive to proof mass displacement. The second feedback element is connected between the proof mass and the output signal and its charges change in response to proof mass displacement.
